How to choose a suitable car compressor, varieties and device. Compressors for swing tires. What are there and how to choose a compressor for pumping automotive tires car pump from cigarette lighter diagram of its device

Many car owners have repeatedly come across the problem of a shredded wheel. The reasons for this are enough: puncture, side cut, problems with the base of nipple or spool, descending the tires during the cold season and so on. First of all, it is necessary to eliminate the cause of tire slimming, otherwise this problem may turn into a constant threat to the health of the car itself.

What is it worth pumping tires?

The correct air pressure in tires increases their service life, and is also one of the important items to ensure the maximum capacity of the car. Some drivers probably did not even think about the fact that the rubber is not absolutely hermetic material. Therefore, even a new and whole bus with time can pass the air.

That is why it is necessary to regularly monitor the pressure in the wheels and, if necessary, pump them. Pumping or tire deficiency contributes to rapid wear. Low tire pressure badly affects the car charter and its brake abilities. In this case, the car can stop listening to the steering wheel, which is dangerous for life. Also significantly increases fuel consumption. When the resistance increases, the temperature rises, and the tire may even burst.

On the other hand, if the tires are thrown, the protector is strongly and quickly flashes in the central part. The car acquires signs of tough suspension, the effect of the "ball" is observed, the braking path increases. The controllability of the car is also worse and there is a risk of puncture or explosion of the wheels.

Types of compressors

Constructive compressors can be divided into three groups: piston, membrane, rotary. For passenger cars Mainly uses a piston or membrane compressor, so it is worth considering them in more detail.

The basis of the work of the piston compressor is the piston and the camera. By performing progressive movements, air compression occurs. When the piston moves back the camera is filled with air, and when moving forward, it goes into the bus.

Advantages of the piston device:

• high performance;
• ensuring a large pressure;
• can operate at low temperatures;
• durability.

In such a type of compressor, the location of the rod of the piston plays an important role. In this case, the compressor is in great preference in which the connecting rod is located on the motor shaft. However, it can be connected to the shaft with the help of additional elements, and it does not differ in such a long service life as the first option.

When buying, preference is better to give the steel body of the product. For large loads, the device may overheat, so you need to take breaks for a few minutes.

Membrane compressors are arranged on another principle. Air discharge occurs due to the rubber web. It is this part that performs progressively return movements. If the rubber diaphragm failed, it is easy to replace it with a new one. This type of device is also called vibration.

Advantages of the membrane device:

• reliability;
• durability;
• lack of driving elements;
• maintainability.

The disadvantage is that the unit cannot be used at very low temperatures, since rubber parts quickly freeze. Compared to the piston compressors, the devices have less productivity.

How to pump the wheel with a compressor?

To begin, determine the current and required atmospheric pressure in the tires. Normal indicators for them must be listed in the operating manual. It should be borne in mind that there is no general standard for all wheels, so the pressure is selected individually. The compressor is equipped with a pressure gauge, which shows the air pressure in the wheel.

So, the podachka begins with the fact that it is necessary to gently remove the cap on the valve. Then put on the compressor hose on the valve. The power of the compressor itself is connected, as a rule, through a car cigarette room.

Now you can look at the pressure gauge. If it shows a low pressure, then it is necessary to immediately begin the wheel swap. Focusing on this indicator, the air pressure should be lifted to required level. No need to exceed this indicator, since the pumping is also undesirable.

And also, consider that the tire pressure is measured when the swap process does not go. After that, the hose must be disconnected from the wheel and shut the protective cap nipple. So it should be done with each wheel.

How often do you need to pump tires?

Measuring air pressure in the wheels of the car should be periodic. You should not wait until the wheel is completely lowering, since the abnormal value can lead to more serious consequences. By clicking on the link you can study such information in more detail. At the first signs, you should contact the service or pump the wheels yourself. The procedure should be repeated every month and when changing the ambient temperature.

A good driver has a pressure control in wheels permanently. It depends on the right size, starting from the fuel consumption and ending the car stability on the road. And maintaining the necessary pressure values, it is necessary to regularly pump or even pump the desired wheel. Now for these purposes, special products use, but their abundance and variety of characteristics makes think about how to choose automobile compressorsuitable for your car.

What is it and how the car compressor is arranged

This is a specialized device that serves to pump tires and connected to a used car. Exist various options The design of such products, one of which is shown below.

The principle of operation of any automotive compressor is quite simple - the electric motor is connected to a used car (through the cigarette lighter, or using special clips to AKB). A working electric motor actuates the air compressor in the wheel.

As a rule, a similar device is characterized by a certain set of parameters, among which you need to pay attention to:

1. type of compressor;
2. performance;
3. current consumption;
4. the value of the pressure being created, the type of device controlling its magnitude.

Problem How to choose a car compressor is reduced to the correct estimate of these parameters, after which you can define the device, better than other requirements.

About the types of automotive compressors

The term compressor implies in this case two values:

• finished product, serving to pump tires;
• a device that carries out the air and feed to the wheel.
• The following types of compressors are commonly used:
• membrane;
• piston.

The principle of operation of piston compressors is based on the fact that a special mechanism driven by an electric motor, it sucks the air with the help of the piston and supplies it into the wheels, thereby pumping tires. With sufficient power of the motor and the volume of the cylinder, such a product is able to create a large pressure. Thanks to this, they can enjoy the drivers of light trucks and heavy SUVs, providing pumping tires to the required value.

The disadvantages of this type of compressors include:

• overheating of the engine and the compressor itself (pairs of piston / cylinder), as a result of which is limited to the time of continuous operation. In such cases, it is necessary to take a break at least fifteen minutes before it is re-using;
• cylinder wear and piston. This may be a consequence of getting along with air particles of dust inside. As the details wear, the developed pressure is falling and the tire pumping time increases;
• repair of this type of product is impossible.

At the membrane compressors, the principle of operation is completely different. In this case, the air supply when pumping tires carries out a special web, moving returnable. Among the advantages of this type of compressors should be noted:

1. the presence of only two driving parts, which provides a smaller probability of failure;
2. maintainability, damaged membrane can be replaced.

The disadvantages of such compressors are usually referred to:

1. low pressure generated (no more than four atmospheres) when pumping tires. However, justice should be said that for the normal operation of passenger cars is no longer required;
2. poor work at low temperatures.

About other parameters affecting the choice of automotive compressor

Not only the type of compressor affects the choice. The possibility of its use to pump the tires of your car will depend on:

Developed pressure and control devices

It is always necessary to proceed from what is required to maintain a particular machine. If you have an ordinary passenger car, then there is no need to use a compressor capable of issuing eight atmospheres. After all, it takes no more than three for its normal operation.

But if you are the holder of a heavy SUV, then you need to use a product that provides greater pressure. For these purposes, the piston compressor is best suited. Choosing it, you need to pay attention to the installed pressure gauge. Its scale should allow easy pressure reading, and the instrument itself is to ensure the necessary measurement accuracy.


Usually an arrow meter is used, but there are also digital on some models, which is more convenient.

Performance

It is usually given in reference characteristics. First of all, it must be evaluated to determine the time required for pumping tires. When performing up to forty liters per minute, you can pump thirteen-fourteen inch wheels of the passenger car, and not very fast. Other sizes on the same task will require much longer.

For reference it is worth leading such a digit - the wheel 175/70R13, pumped up to two atmospheres, contains 20 liters of air. So choosing the compressor for its performance should take into account the characteristics of your car.

Consumption current

This parameter affects the power taken from the on-board network. The fact is that if the current consumption does not exceed fifteen amps, it is quite possible to connect through the cigarette lighter. If this parameter is larger, then it is necessary to feed on the compressor (using special clips and wires) to apply directly from the AKB. It is desirable to make the engine to avoid the battery discharge.

Here is a list of data that you need to know to properly choose a car compressor. Of course, there are other parameters, such as such as appearance, Additional functions, dimensions and weight, but those discussed above will be determining when the device you need is selected.

The car compressor has long moved from the discharge of exotic products to the most ordinary, which each driver uses. That's just big choice The various performances are able to put anything in a dead end. If you know the main characteristics for which you need to pay attention, the choice of compressor will not represent any difficulties.

Compressors are in great demand in industry and construction. They are used in medicine and dentistry. In each household refrigerator and air conditioner, the compressor plays the role of the main driving mechanism. The release of compressor technology is considered a separate industry, which is rapidly developing, absorbing the achievements of electronics and new technologies. Knowledge of the device, rules of operation and technical service will help make right choice When buying a compressor, as well as solve problems associated with the rejection of the aggregate failed.

What is the compressor and how it works

The name "Compressor" comes from the Latin word compressio, which means compression. This is a device for creating increased gas pressure and feeding it in the desired direction. Depending on how the task is achieved, the compressors are divided into groups. Distinctive feature Each type of these devices is a constructive solution of the compression and air supply process. In general, all aggregates are divided into two large categories - voluminous and dynamic. Each group, in turn, has its branching.

The variety of compressor machines is due to a wide range of their applications.

Dynamic compressors are based on the principle of compression of gases by means of mechanical energy. There are axial and centrifugal machines depending on the direction of air movement, as well as from the type of rotating wheels. One of the bright representatives of this group is a turbocharger. Its design is based on the interaction of moving air with a fixed lattice and rotating drive blades.

In the compressors of dynamic action, the gas is compressed in due to mechanical energy, which is supplied from the rotating shaft

Volume compressors use the gases property to shrink when the size of the closed space is changed into which it is placed. Reducing the dimensions of the working chamber leads to an increase in pressure. This group includes the majority of household and industrial aggregates, there are more than 10 different types of them:

1. Piston. The most common type of injection machines that serve for gas supply or steam under pressure. Constructive solutions The great set, however, the main feature of the piston pump is considered to compress the working medium due to the reduction of the volume inside the cylinder produced by the progressive return movement of the piston. Such compressors have found use in heavy engineering, in chemical, textile and refrigeration. According to constructive features, piston devices are classified on vertical, horizontal, angular. There are multi-stage piston compressor stations - with a gas compression to a high pressure, there is a risk of explosion or ignition of inhalation of oil accumulating in the pipeline and the surface of the exhaust valves, therefore this procedure is carried out in several steps.

   The piston compressor increases the pressure of the gas due to the reduction of its volume at the workshop of the piston

2. Screw. Experts consider this type of machine the most economical. That is why screw compressors are used on mobile compressor stations, in mobile military equipmentships refrigeration equipment. Compared with other types of injection devices, electricity savings can reach up to 25-30%. In addition, small dimensions are noted, reliability and low cost. The essence of the structure consists of two coaxial-rotating rotors made in the form of the Spiral of Archimedes. Screws move synchronously, not in contact with each other, and do not need lubrication. Inside the rotor housing are the suction and discharge channels of the gas, as well as seals and sliding bearings. Gas is compressed by portions as the cameras are filling and issued in the accumulative tank. Due to this, the unit has high performance. Recently, not only two-channel, but also four-channel compressors, whose productivity is even higher. According to experts, with such a design, additional savings are reached from 10 to 15%.

   Screw compressor pumps air under pressure due to synchronous rotation of two shafts with screw blades

3. Rotary-gear. Characterized by a long service life, relatively simple design, balance and high level of purity of the injected gas. Used to supply air to engines internal combustion, Having pusing the lamellar models. The rotary gear compressor is characterized by optimal pressure dependence on the outlet from the speed of rotating rotors, which favorably affects the change in the mode of operation of the engine. In the process of transferring air from the suction valve to the outlet pressure, it practically does not change, so such devices are called compressors with outdoor compression. As a result, this species functions effectively only for a small level of working pressure change. Other flaws are in the presence of pulsations of the injected air flow and high noise when working. In case of violation of the gaps between the details there is a sharp drop in the aggregate efficiency.

   Rotary-gear compressors can be designed according to a water or air-cooled pattern.

4. Membrane. This variety of volumetric devices, which is very well suited for raising the pressure of a small number of vapors or gases to a low level. As can be seen from the name, the main working mechanism in this type of compressors is the flexible membrane made of rubber, rubberized fabric or metal. Oscillations are caused artificially, with mechanical exposure. It can render a rod, driven by a rod or hydraulics - a liquefit column resting in the lower part of the movable membrane. Instruments of this type are used in industry and in laboratory studies. The duration of operation directly depends on the quality of the material from which the membrane is made. Multilayer composite materials that can withstand multiple oscillations and deformation are often used.

   The membrane compressor compresses the air due to the flexible membrane, which vibrates from the mechanical effects of a row making reciprocating movements

5. Liquid-ring. Used B. agriculture and the food industry (for the production of sugar, yeast, non-alcoholic beverages and bread). Thanks constructive features It is well protected by air from pollution with oil pairs. Despite the low efficiency and enhanced dimensions, the waterproof compressors are distinguished by reliability in operation, there are no noise and, most importantly, gas is compressed with almost no heat release, i.e. isothermally. The principle of operation is based on compressing air mass by more viscous fluid. It is constructively achieved using a cylinder filled with liquid (water), in which the rotor rotates with blades. The sickle space separated by the segments of the blades is the functional volume of the device. The absorbable air is compressed and displaced through the injection pipe of the compressor.

   In industrial compression installations, use the principle of air compression using water

6. Ruts Blowers. Low-pressure compressors patented by the Ruts brothers in 1860 in the United States. A simple and effective design, which has been improved and repeatedly modified over time. Nevertheless, these aggregates are used in technique to today's day. Their output indicators reach 16,000 m 3 / hour and additional pressure of 1,000 mbar. A distinctive feature of RUTS blower is the lack of lubrication in the working mechanism. Minimum of rubber details makes the mechanism very reliable in operation. Low vibration and compactness allow you to use an aggregate to download aggressive and explosive gases. Cases, as a rule, asynchronous electric motor.

7. Spiral. The compression of the working gas environment occurs due to the interaction of two spirals, which are eccentric moving among each other. Since the spirals do not come into contact and the gaps constantly remain between them, the engine test of this type of compressors is large enough. However, when assembling and commissioning, rigid requirements are made to the manufacturer. Violation of technological gaps in several fractions of a millimeter can lead to the functional unusability of the structure. The frequency with which the spiral moves is calculated by several tens of thousands of revolutions per minute. The disadvantage of the spiral design is the need to host the inner "snail" at the initial stage of operation. It is necessary to run a compressor to smooth technological gaps. This affects the overassment of the working pair.

   In a spiral compressor, working gaps are measured by millimeter shares, so such devices require careful guard

8. Rotary. A variety of volume units, in which there are no suction valves, and only injection ones are used. The axis of the rotor (piston) rotates around the axis of the cylinder, which is fixed. As a result, the so-called sickle space is formed, in which gases or steam compression occurs.

   In the compressor with a rolling rotor, the working cylinder is fixed motionless, and the piston rotates around it

Creating a spiral compressor dated 1905. The idea belongs to the engineer from France Leon Kros. But the introduction of the industry was possible only in the middle of the 20th century, when the level of technology did a serious step in the field of material processing. The mass application has received the construction at the end of the century when the spiral compressors began to use in climatic and refrigeration equipment. It turned out that the efficiency and the level of pressure created at this type of aggregates exceed all the other devices known at that time.

In addition to the above classification, there are other ways to separate compressors:

• by type of leading mechanism (electric drive, engine, turbine);
• on the air outlet pressure (compressors of low, medium, high and ultra-high pressure);
• in terms of performance, expressed in the amount of compressible gas (in m 3) during a certain time (min., hour).

How to choose a compressor

Obviously, the choice of compressor depends on the target. No one will apply a car compressor, for example, in the refrigerator or vice versa.

The main consumers of atmospheric injection machines are motorists, builder masters, locksmiths, furniture makers. As practice has shown, the most appropriate screw and piston compressors are most appropriate. Moreover, oil-free uses for small volumes of work - tire swaps, painting of small parts of the body, etc., and more powerful - oil piston and screw compressors are used for piston tool.

Piston injection machines appeared earlier than others and today are the most common.

The working pressure of such aggregates reaches 25-30 atmospheres than other compressors do not boast. The main advantages are low cost, simplicity of design and lightness in repair. In addition, the devices are insensitive to the composition of the air environment - dust, moisture and temperature differences are practically not affected by the quality of work. Service life properly operation And timely service is very long. The disadvantages of piston compressors include the need to regularly replace parts that quickly wear out - piston compression rings, glands and valves, as well as high level Noise pressure that reaches 95 DB (it is comparable to the root of a locomotive running along the railway). On the production, which intensively use such compressors, highlights special rooms to accommodate the "noisy" equipment. Based on the listed features, piston machines are used in the following cases:

Screw compressors are beneficial from piston in that there are no quick-willed parts in the design. Screw block, which is the main work mechanism, is designed for service life of 15-20 years without overhaul. The lack of parts with progressive motion and valves makes screw compressors very reliable and durable. The dynamics of compressed air supply to a lesser extent depends on the speed of rotation of the drive shaft, while in a piston compressor, the slowdown of the piston leads to pressure failures. Due to the fact that there are no pistons and connecting rods in the design, vibration and noise are reduced. Therefore, such aggregates do not require separate room for installation. In addition, the compressor emits a large amount of heat that is formed during the compression of gases. It can be used to heat the working space in the cold season. The cost of screw compressors is an order of magnitude higher than piston devices. This is due to more complex production. But such equipment pays for faster, as it is more productive and economical. The use of "screws" is justified in cases where large quantities of compressed air in uninterrupted mode are needed.

The main parameters for which you should pay attention to when selecting a working tool:

1. The pressure generated by the compressor. One of the most important parametersFor which you can judge the performance characteristics of the product. Pressure is measured in the atmospheres (atm.) Or in bars. To not be confused in units of measure, you need to know that one atmosphere is approximately equal to one bar. Knowing the maximum compressor pressure value, you can determine which tool it is suitable. In practice, the compressor is always acquired. If, for example, pneumatic wrench is driven by air pressure at 6-7 bar, it is recommended to choose a compressor compressing air to 10 bar.

   Wrench is powered by compressed air supplied from the compressor

2. Performance level. It is expressed in the number of liters of air pumped per minute. It should be paid to the fact that the piston machines present the phenomenon of the "air failure" - lowering productivity during operation related to the changes in the external air environment. Therefore, such a compressor is chosen with a reserve of performance up to 20% of the nominal.
3. Power. The value denoting the working potential of the equipment. In simple language, power displays the speed with which the machine can cope with the work. It is measured in watts and is displayed in the technical passport of the device. As in the first two cases, the calculated value of power should include an error in the distinction between the nominal and real meaning. Over time, due to wear of parts and engine generation, power decreases, which can lead to incompatibility with the working tool. Based on this, it is recommended to acquire compressors with a power exceeding the set by 20-25%.
4. The volume of the receiver. Immediately after compression, the air falls into a cumulative metal tank, which serves to stabilize air supply. In technical terminology, it is called the receiver. The larger the volume of the receiver, the less pressure drops will be during operation. But it should also be borne in mind that the compressor will need more time to download the required amount of air into hermetic capacitance.

   Depending on the power and performance, compressors can be equipped with receivers with a volume of 25 to 250 liters.

5. Nominal working voltage and current power. In domestic conditions, where there is no three-phase current connection - single-phase equipment designed for voltage 220 V and current strength 6 A. In domestic networks, the current frequency is 50 Hz. By purchasing an import compressor, you must make sure that it is compatible with these parameters. Otherwise, overheating and premature output of the instrument failure is possible.
6. Weight. As a rule, it is directly related to the capacity and capacity of the compressor. Household models, calculated for home and "garage" applications, have a mass of up to 5 kg. Such a compressor is more mobile, easily moved and transported. Professional models installed inpatient, weigh 20 kg and more.
7. Dimensions. This indicator is directly related to the weight of the compressor. From what sizes will the device, it depends on the convenience of work. If it is often necessary to move, it is advisable to choose a small compressor with a transfer handle. Powerful and heavy devices with large-volume receiver are installed on mobile platforms that are rolled on wheels.
8. Noise pressure indicator. It is believed that comfortable and harmless to health noise level - up to 70 dB. Many manufacturers solving this problem use additional noise-imaging and anti-vibration constructions. Noise level information is reflected in the technical passport of the product.

How to use a compressor

Preparation of the compressor to work is an important stage whose observance is associated with long-term and serviceable operation. It consists of the following consecutive stages:

1. Careful study of the instructions attached to the product by the manufacturer. The data provided in the technical passport must coincide with the data reflected on metal signs. They are located at the bottom of the compressor housing.
2. Checking the configuration and lack of mechanical damage on the housing. When detecting defects of the case, receiver or connecting hoses need to be eliminated.
3. Installation in the working position. Wheels and shock absorbers are put on mobile models in accordance with the package. The unit is located in such a way that the control is carried out freely and easily. No extraneous items on the housing are not allowed. If the compressor has a belt transmission, it is necessary to put it at a distance of at least 1 m from the walls. The floor surface in the room where the work is made should be smooth.
4. Check the oil level in the engine crankcase. The red label indicates the maximum allowable amount of lubrication. If the oil is not enough, it is necessary to accurately add it, without overflowing through the edge and not allowing the hitting of the belt and other parts.

   The oil must be flooded to the level denoted by the Red Tag

5. Connecting the device to network nutrition. Some devices are important not to confuse the connection of phase and zero wires.
6. Connection of the receiver nozzle with a pneumatic tool fitting. For proper connection Air booming starts the engine power relay automatically. Self-adjustment of the relay is invalid and stops warranty obligations from the manufacturer.
7. Instruments equipped with an overload engine protection function are disconnected with too long work or voltage drops on the network. It should be remembered and not to look for the cause of the stop in the mechanical part of the device.
8. After the end of work force aggregate You need to completely disable and release excess air from the accumulative tank (receiver). For this, serves a special valve installed on the tank housing.

   After the end of work, it is necessary to store excess air from the receiver, opening the check valve

In some compressors, instead of the oil level pointer applies probe. To determine the presence of lubrication, the dipstick is lowered into a special opening, closed by a plastic lid.

If it is not possible to connect a car compressor from a regular cigarette lighter or you need to save the battery charge, it is possible (and in some cases recommended) connecting terminals directly to the battery. For this purpose, special clamps are used in the compressor package for tire swap.

Safety technique

Before starting work:

• wear work clothes, shoes and collect hair under the headdress;
• check the completeness and stability of the apparatus;
• make sure the pressure gauge and the pressure fuse switch;
• equip workplace In accordance with personal safety standards.

During working with compression equipment, it is prohibited:

• connect to the electrical network without grounding;
• leave a working compressor without supervision;
• direct the air jet towards people;
• allow children and minors to control the compressor;
• use knowingly defective aggregate.

After completion of work, it is necessary:

Care for compressor

The compressor maintenance consists of the following regulatory work:

The most common breakdowns and repair doof

If the compressor is purchased recently and the warranty service period has not yet ended, all breakdowns are obliged to eliminate employees of the service organization. But if the warranty is over and repairing equipment is independently, learn the table below.

How to make a compressor with your own hands

Folk craftsmen have long learned to make compressors with their own hands. Some independently manufactured devices are capable of performing work not worse than factory. As a rule, gas cylinders or fire extinguishers are used as receivers. And the role of the discharge machine executes the compressor from the served refrigerator.

The simplest apparatus for the production of compressed air consists of a compressor from the old refrigerator, a gas cylinder and a pressure gauge

The performance of such a device will be small, but with it you can apply a uniform layer of paint on any surface. To do this, either the paintopult or airbrush.

Video: how to make a compressor from the old refrigerator

Using a pneumatic tool, as well as sandblasting devices, remember that with a negligent circulation, the compressor from the assistant in the farm can turn into a dangerous device that can cause injury or become a threat to health. Only compliance with safety safety and careful attitude to work guarantees personal security.

The compressor is connected using "crocodiles" to the battery terminals. This type of connection is more reliable than connecting from the cigarette lighter. The fact is that when the compressor is connected from the cigarette lighter, the cigarette lighter itself can be spoiled (the fuse may be poor quality, or may not withstand the load). To the pros, except reliability, you can attribute versatility - once connected and pumped all four tires, as there is no need to open the door with the right either on the left side. It is worth noting that such a reliable type of connection can be convenient not to all motorists. For example, many girls do not like to open the hood and chain the "crocodiles" to the battery terminals. In addition, when connecting, between terminals and "crocodiles" may not be weak. Of course, all this can be avoided by turning your opinion on compressors with another connection.

As mentioned above, such a type of connection is most secure due to the absence of the "spark" effect (stuck the plug into the cigarette lighter and you can safely pump up).

The minuses should include less reliability.

This type of connection is the rarest, but most functional. Compressor with such a connection can be used not only to swipe automotive tires, but also to swing tire strollers, ball, bicycle tires, etc.

Maximum pressure

In general, compressors with such meanings are the optimal choice, since most passenger car tires are enough atmospheres.

These compressors will suit not only car drivers, but also cyclists. The fact is that the tires of some bicycles are pumped up to 9.5 atm.

Pumping rate

It is measured in a liter / minute with standard values \u200b\u200bof 2 atmosphere. This indicator directly affects the tire pumping rate. With this in mind, several groups can be distinguished.

Initial class compressors for pumping speed. In such compressors, a connection from the cigarette lighter is used. In other words, compressors of this class have a small power, therefore, do not need to be connected from the battery using "crocodiles". These compressors will fit novice motorists. For example, I bought a passenger car and you need to buy a compressor for a little money.

Middle class compressors for pumping speed. The number of such compressors is the biggest. Also, the compressors of this class can rightly consider the "golden middle" since such compressors are capable of pumping tires quickly and efficiently and efficiently passenger car. Such compressors should choose not only drivers of sedans, but also drivers of SUVs, crossovers.

Compressors with the highest pump speed. Accordingly, the price increases the greatest speed. The advantage of such compressors should be considered the tire pumping speed, which in some cases significantly reduces the operation time of the compressor and allows you to quickly move into the path. Here, the connection type will be from the battery "directly".

Type of manometer

Pressure gauge is a device that measures air pressure in the compressor. Measured in the usual bars (atm) or in overseas PSI. Types of pressure gauge Two: analog and digital.

There are two types of compressor location: on the housing and on a pneumaticistole or hose. The second option is more convenient, since to control the readings you do not have to run every time to the compressor.

Fasteners on nippel

It is worth saying that this parameter is subjective and when choosing a compressor is not worth paying a lot of attention to this factor.

Fasteners on nipple there are two types: with brass fitting and with a flag clamp. The first is more reliable, but it takes a lot of time to twist and the wheel loses more air when disconnected. The hose with a flag clamp to deliver and remove much faster, but the fastening itself is less reliable, especially when working with high pressure. The clamp is usually plastic and there is a risk that it will break.

Running valve

Price ranges

Entry compressors, possess basic functions. The pumping rate ranges from 10 to 35 liters / minutes. In general, it is worth paying attention to compressors with a pumping rate of 25-30 liters / minute. Compressors with such values \u200b\u200bwill be best selection In the ratio of the price / rate of inflation. Compressors of this price range have analog pressure gauges, and the type of connection from the cigarette lighter. Such compressors will suit most drivers, due to the small price.

Compressors of the average price level having additional features: built-in flashlight, connection "from the battery". In general, the pumping speed of such compressors is 35 liters / minute. Such compressors are a "golden middle" among price categories, due to the ratio of basic parameters to the price. If there are such moneyIt is definitely worth paying attention to these compressors.

Compressors of this price segment have a broader functional. For example, some compressors have in its presence built-in sensors for testing the generator and testing AKB. Functions are good enough, especially in terms of primary diagnostics. The high-speed characteristics of such compressors reach indicators on average 40 liters / minute. In some devices, you can find not only the connection from the battery "directly", but also the presence of a digital manometer that will facilitate control of indicators. In such compressors there are wires with a total of 4-5 meters, which significantly facilitates the carrying of the hose from one bus to another. Such compressors should be purchased to those who are willing to overpay for additional functions of the primary diagnostics of the generator and the battery.

As a rule, compressors of this price range are on average have the rate of pumping 55 liters / minute, connected from the battery "directly", have long hoses of ~ 7 meters necessary drivers of long trucks. Some, stuffed with additional features: digital pressure gauge, generator tester, overheating protection. Also such compressors can be used in wide temperature ranges. Such compressors will suit the drivers of large trucks.

The car compressor came to shift the manual and foot pump to swing tires. The most pleasant advantage of this device is that it is fully automated and in order to pump the wheel does not need to apply physical effort. Convenient when the compressor is always at hand, wherever you are. However, it happens that it fails and then repair may be required.

Why is the compressor today is the essential thing for the driver? After all, there are so many hundred and tires where you can pump tires, and if necessary, make other repairs. Everything is simple. The wheel can make anywhere, for example, in mountainous areas or in the country array, far beyond the city - there will be no specialized workshop there. And then, the control over the situation is better not to miss and independently eliminate the problem, quickly, without excess spending and trouble.

Causes of compressor breakage

The most common cause of the malfunction of the automotive compressor is the banal burnout of the fuses. A block fuse or the one that is located on the wire can be burned. Such a breakdown is not serious and eliminates very quickly. Especially since spare parts to produce repair, you can buy in almost every store, for example here exist.ua.

Also, one of the options in which the compressor fails, implies damage to the power wire. Determine this trouble is very simple. It is enough to visually explore the wire and find the place of donkey or don. With this problem, you can also cope easily and quickly probably every man changed the plug on the iron wire.

There are more serious reasons for the inoperability of automotive compressors. Suppose when fireing a winding of an electric motor or a viburnum, it is rarely possible to save the patient.

If you find that the compressor turns on, but does not give necessary action, that is, does not pump air, look for a problem in the wear of the piston or fluoroplastic ring. In this case, it will be cheaper to purchase a new autocompressor than to repair and buy new spare parts.

But most often the problem is not sharp and requires a small intervention, replacement of spare parts or components. This is usually a failed hose, a valve, dressed on the nipple wheels, rubber ring-gasket, brushes, nozzles.

Features of autocompressors

Due to the fact that in the configuration of the automotive compressor there are various nozzles, it can be used not only for driving a car tires, but still for balls, inflatable boats, bicycles, etc. That is, the compressor plus the nozzle is a universal device that allows you to solve several tasks at once.

In order to repair the compressor, it is important to know its device and features. So, each representative of automotive compressors is equipped:

• Electric motor;
• Pressure gauge;
• Cylinder;
• Piston;
• Other components (cables, brushes, pads, nipples, nozzles).

On its device distinguish the membrane and piston compressors. The principle of operation of the membrane compressor is to compress gas, due to the fact that the translational movements of the membrane reduce the volume of the chamber. The membrane, sandwiched between the cylinder and the lid, begins to fluctuate and acts as a piston.

The piston compressors are equipped with a special piston, which when connecting with crankshaft, sucks air masses. They enjoy much greater popularity among motorists.

To ensure the greatest pressure, piston compressors work in a stepped mode. Thus, the compressed air mass is distilled from one cylinder to another, by means of a cooling tube. The volume of one cylinder is intentionally more than the second, but the latter lives the air, increasing the efficiency of the device.

Weak membrane compressor places

The weakest part of the membrane compressors is a membrane. If foreign particles accumulate in the gas cavity of the unit. Important aspects of working with such a compressor are:

1. Maintain block cleanliness.
2. Exclusion of moisture and dirt in the membrane block.
3. Timely replacement of spare parts (membrane, gas valve, pressure limiter).

Weak Piston Compressor Places

The most common problems with a piston compressor, this is:

• The compressor refuses to start;
• No air emissions in the receiver, although the motor works;
• Knocks out fuses;
• Air pressure drops sharply;
• Incorrect operation of the automatic thermal protection;
• The humidity of the air injected by the compressor is raised;
• Motor operates at elevated vibrations;
• The location of the hose and nozzles wipe and the air pokes.

What if the compressor does not start

If the device refuses to work, you need to produce certain diagnostic actions using an indicator screwdriver. We explore whether there is a phase, and whether the stress is supplied. If everything is in order with the phase, go to check the fuses, perhaps they melt. If it is precisely in this, then just replace the fuse. It is important to remember, making repairs, installed parts must be equivalent.

After replacing, everything should earn, however, it happens that the fuse bravely burns out. This suggests a possible short circuit. Repair needed. Sound the scheme. When defective parts are installed, replace them with new similar spare parts.

The refusal of the compressor can be associated with the failure of the pressure control relay settings. In order to diagnose this problem, do the following: Release the air and start the compressor again. If you hear the sound of the running motor - reset the settings, the motor does not function, you need to replace it. Remember that with intensive work of thermal protection, you need to cool the motor at least 20 minutes, it normalizes the operation of the compressor.

Special attention deserves a situation when when the device is turned on, the fuse and thermal protection fail. If the problem is only that the installed fuse is not designed for the operating power of the unit, then the repair is reduced to a simple replacement of spare parts. But if the relay came out of the order, do not try to climb there yourself. In order to get a skilled renovation, go to the service.

In a situation where the piston is unfamiliar, you need to disassemble the device. When making a repair, release air, clean the valve from dirty formations, if the pressure continues to fall - the problem in the valve, it requires replacement.

Where to take compressor repair spare parts

With such an abundance of automata and places for the sale of components, the head can simply go around. Where to acquire spare parts for repair or new nozzles. In principle, there is no big difference in the sale places of spare parts. This is a matter of convenience for everyone. Someone goes to a specialized store, then on the meal, and someone is convenient and profitable to order spare parts over the Internet. The taste and color as they say.

The main thing, when making the purchase, do not run into the fake. Original spare parts - the key to the long service. Request a certificate or warranty card by purchasing new parts for fixing compressors from the seller.

In general, the repair of the compressor is simple and can be produced, without having appropriate experience or qualifications. Although it is better to prevent breakdown in advance, just causing technique.
