Pumping tires! Which car compressor to choose. Compressors for tire inflation. What are and how to choose a compressor for inflating car tires Car compressor how to use

home / Terms

A car compressor is a device that has greatly simplified the tire inflation process, which has traditionally been done with a hand or foot pump. This unit can operate in automatic mode, has compact dimensions, and inflation of tires with its help does not require the use of physical efforts. Although the autocompressor is not complex in design, some of its components may fail over time. To repair the device yourself, you need to have an idea of how it works and how it works.

Compressors for pumping wheels are of diaphragm type and piston type. Both types of devices are designed to compress air and differ from each other not only structurally, but also in the principle of operation.

Membrane devices

If you look at the device of a membrane-type automobile compressor, you can understand that the main element of the unit, with the help of which air is compressed, is the membrane... It is made either from rubber or metal.

The diaphragm autocompressor consists of the following elements:

an electric motor that drives the drive of the compressor unit;

a compression chamber with 2 valves;
rubber, polymer or metal membrane located in the compression chamber;
a rod connecting the piston to the diaphragm;
a piston connected to a rod and a connecting rod;
connecting rod and crank;
the crankcase in which the crank mechanism (KShM) is located.

Autocompressor works according to the following principle... The crank converts the rotation of the drive shaft into the reciprocating motion of the connecting rod. The one connected to the piston sets it in motion. The piston, moving up and down, drives the diaphragm with the help of a rod. Moving down, the diaphragm creates a vacuum in the compression chamber, which opens the intake valve. When the latter is opened, the chamber is filled with air. Moving up, the membrane provokes the closing of the intake valve, and the process of air compression begins. When a certain degree of compression is reached, the exhaust valve opens, after which air under pressure enters the hose connected to the tire. When the membrane moves down, a vacuum is again created in the chamber, from which the outlet valve closes, and the inlet valve opens. Further, the entire process described above is repeated.

Important! Due to the fact that the compression chamber is hermetically separated from the crankcase, the air leaving the apparatus does not have any foreign matter. In addition, in the membrane units, air leakage through the oil seals or piston rings is excluded, which has a positive effect on the performance of the autocompressor.

Piston units

Piston type tire inflators the main part is the piston.

Consists given view car pump from the following assemblies and parts:

an electric motor driving the drive of the apparatus;
compression chambers (cylinder) with inlet and outlet valves;
air filter;
a piston having an o-ring;
KShM, consisting of a connecting rod and a crank;
the crankcase in which the KShM is located;
pressure gauge, which is designed to monitor the level of pressure in the tires and can be installed on the cylinder or hose.

The device works as follows... The KShM is driven either by a gear transmission or by a direct drive. It converts the rotary motion of the drive shaft into reciprocating, which causes the piston to move up and down. The piston, moving downward, creates a vacuum in the cylinder, as a result of which the intake valve opens. Air, passing through the filter and the opened valve, enters the cylinder. Due to the upward movement of the piston, the air in the cylinder is compressed. When a certain pressure level in the compression chamber is reached, the exhaust valve opens, through which air exits the apparatus. Further, when the piston moves down, the exhaust valve closes, and the intake valve opens, and the cycle repeats.

Common Reciprocating Compressor Problems

Since the design of diaphragm autocompressors is significantly different from the piston device, then some breakdowns of these devices will be characteristic only for a certain type of units.

The most common malfunctions of piston autocompressors that can be eliminated by hand include the following:

the device does not turn on;
the engine of the unit works, but does not pump air;
the device does not create the required pressure;
the compressor shuts down spontaneously.

The device does not turn on

Tire inflation compressors have power cable (s) to connect to a 12 V power supply. Some models of devices are connected to the car's cigarette lighter, and some to the battery.

If the electric pump does not turn on, then first of all, check the power cables for damage. They can be “ringed” by the tester. Also, if the compressor is connected to the cigarette lighter, then you need check the integrity of the fuse installed in the plug. If the fuse blows, it must be replaced.

Advice! Most often, owners of Tornado auto pumps face a blown fuse. Therefore, before connecting the device to the cigarette lighter, it is necessary to check the voltage in the latter.

In extreme cases, the device may not turn on due to failure of the electric motor... Most often, motor windings burn out due to overheating. It is easier to buy a new car compressor, since repairing a car compressor engine will cost 80% of the cost of a new unit.

The engine of the unit is running, but no air is pumping

If, when the device is turned on, the sound of a running engine is heard, but no air comes out of the hose, then, in order to diagnose the unit, you will have to parse it:

unscrew the 4 screws holding the crankcase cover;

you should also unscrew the 4 screws installed on the piston head;

remove the cylinder head.

A valve is installed in the cylinder head, which is a common reason that the device does not pump... To eliminate the malfunction, it is necessary to remove the seal and the valve disc from the piston head.

There is a small sealing ring that can wear out over time. When it is worn out, the valve does not fit tightly and allows air to pass through. As a result, no compression of the latter occurs. Also, sometimes this ring can be displaced from its seat. If this happens, the valve will also not be able to close. It is not uncommon for a valve plate to simply break. In this case, it must be replaced. This detail, like other spare parts, can be purchased in online stores.

Another reason that the device does not pump may be loose screw, by means of which the crank is fixed to the motor shaft.

If the screw is unscrewed, then the motor shaft will rotate, and the KShM will remain stationary.

The device does not create the required pressure

If, when trying to inflate the tires, it is not possible to achieve the required pressure, then the cause of the problem may be, as in the previous case, the valves. Various contaminants can accumulate under them, interfering with a good fit. To repair the tire inflation compressor, you will need disassemble the piston head and clean all parts well from accumulated dirt.

Sometimes insufficient air pressure at the inlet from the unit may be due to deformation of the o-ring wearing a piston.

To remove the piston, you need to remove the liner jacket and the liner itself.

The piston o-ring may be deformed due to overheating of the unit... To align the ring, you must first soften it. Either Thinner 646 or WD-40 fluid can be used for this purpose. After the ring becomes soft and pliable, it should be aligned, and the sleeve and jacket installed in place. You can check whether the piston moves in the liner correctly by turning the engine shaft.

Compressor shuts down spontaneously

Some models of autocompressors have overheating protection... For this reason, the device can turn off spontaneously, for example, during prolonged operation. But overheating of the unit can also be caused by a factory defect, especially in inexpensive models. There is a flaw in poor fit of the sleeve of the apparatus to the shirt... In this case, the heat removal from the piston unit is reduced and, as a result, the piston head and the engine overheat.

In this case, the repair of an automobile pump will consist in eliminating the gap between the sleeve and the jacket (you can use thin sheet aluminum or thermal paste). Thin sheet aluminum can be “mined” by cutting a regular beer can. You need to wrap the sleeve with aluminum, and insert it tightly into the shirt. After these actions, the heat transfer will improve, and the compressor will stop spontaneously turning off.

Diaphragm autocompressors malfunctions

Diaphragm autocompressors break very rarely... Although they are characterized by some breakdowns inherent in piston devices: damage to the power cable or blown fuse in the plug used to connect to the cigarette lighter.

But still, the main element of a tire inflator that can fail is membrane... Most often, it is made of rubber or other plastic material, which, when low temperatures coarsens and becomes inelastic. If such an autocompressor is turned on at a low ambient temperature, then the membrane will simply rupture. In this case, car compressor repair of this type will consist in replacing the membrane.

How to change the pressure gauge in the compressor

Replacing the pressure gauge on a car compressor will be required if it fails. This gauge can be mounted separately from the unit, on the hose, or on the cylinder head.

If the pressure gauge shows incorrect values or does not work at all, it should be unscrewed, and buy similar, with appropriate thread and scale.

Advice! In order not to be mistaken when buying a new pressure gauge, it is recommended to take it with you and ask the seller to choose an analogue.

In some cases, it can be difficult to find the right device. It is easy to get out of this situation: purchase a pressure gauge for a car compressor and tee with matching thread... Attach a pressure gauge with a tee to the end of the hose as shown in the following photos.

Advice! It is recommended to purchase a pressure gauge with a valve installed on it. It will be useful if the tire pressure is exceeded. To slightly deflate the wheel, you just need to press the pressure gauge button.

Hand and foot pumps from car trunks have practically gone down in history, although we all remember them perfectly. Almost every driver now uses a car compressor. It is often compact, works very quickly, as it is powered by the vehicle's 12 Volt on-board network. It does not take a lot of effort and time to inflate the tire. And even if the wheel is flat where there is no car service or tire fitting, you alone will easily pump it up.

Choosing a car compressor these days is not a difficult task. Specialized stores offer a huge number of them. You just need to know if this device is suitable for your car brand in terms of technical characteristics, namely, the volume of tires and the weight of the car.

Automotive compressors are divided into diaphragm and reciprocating. Diaphragm compressors are almost never used due to their low reliability, and their tire inflation rate is low.

It is much better to have a reciprocating compressor. It consists of an electric motor and a cylinder with a piston. Almost all car compressors have a built-in pressure gauge. It is required to monitor the tire inflation pressure. The most reliable in operation is a piston compressor, in which the piston rod is driven directly from the electric motor shaft. However, if there are intermediate drive elements (often made of plastic), this reduces the efficiency of the compressor and shortens its service life. Fluoroplastic piston ring and the aluminum cylinder also improves the durability and life of the compressor due to the lack of any lubrication of this mechanism.

When buying a car compressor, you should take into account the accuracy of the measuring device - a pressure gauge. It should have a well-readable scale. The values on it must be indicated both in the usual bars (ATM) and foreign PSI.

You also need to find out maximum pressure and compressor performance. After all, the speed of inflation of the wheel depends on this. Tires passenger cars mobiles, (except for large SUVs), are pumped with a pressure of up to 2.5-3 atm. To maintain this inflation pressure in the tire, the compressor needs to take a certain amount of time, depending on the performance of the device and the size of the wheel. Therefore, the most optimal options for passenger cars with wheels from R13 to R16 is a compressor with a capacity of 30 to 40 liters per minute. They will quickly inflate tires without much power consumption and can be plugged into a cigarette lighter socket or 12 volt on-board socket.

SUVs, vans, minibuses and trucks need more efficient compressors that consume more power. They are connected directly from the battery terminals. This is not very convenient, however, it is required by the safety of the standard car wiring, which may not withstand the increased load required to power the compressor.

Of course, at the time of choosing a compressor, like any other technique, the trademark plays an important role. A lot of manufacturers offer their products in this segment, but reliability, quality and functionality are important to us. And these indicators are not provided by all. One of the best manufacturers on the market, experts recognize the BERKUT trademark, which has been producing compressors since 2002. BERKUT offers models with different capacities from 40 to 98 l / min. It is very convenient and simple to choose a model. The lineup represented by a scale from R14, R15 up to BERKUT R24. All BERKUT automobile compressors are characterized by high reliability and are designed for a long uninterrupted service life, the manufacturer maintains a guarantee and maintenance of this equipment for the entire service life of the device.

And finally, a tip: check your tire pressure at least once a month. The exact value can only be obtained with cold tires. When the tires are hot, the pressure level in them rises by 10-15%. Also, different levels of pressure in the tires of the front and rear axles are permissible. However, the pressure in the tires on one axle should not differ.

Almost every car owner is familiar with the principle of operation of an autocompressor. It is not enough just to watch the video and read specialized forums, you also need to understand all the intricacies of its work. The device of a car compressor for tires is quite simple, this device is designed to inflate them.

Each car owner needs to buy it, since during operation vehicle tires tend to deflate. The choice must be approached very responsibly and not be guided solely by the cost of the device. Before buying, it is imperative that you familiarize yourself with all the characteristics that the compressor must meet.

Automotive compressor device

It is important to always keep the tire pressure at a certain level in order to operate the vehicle comfortably and safely. These norms are usually spelled out in the instructions for the car.

The tire pressure drops below the recommended level for various reasons. Tire punctures become a headache for the car owner, as well as the fact that even buying high-quality rubber does not completely insure against the fact that compressed air may sooner or later begin to penetrate the tire walls.

Sometimes it is not possible to enter the service station and check the condition of the wheels in a short period of time, and if necessary, pump them up. Therefore, buying a car compressor (tire pump) will be justified. The autocompressor device is very simple. It consists of the following parts:

Cylinder.
Pressure gauge with scale.
The engine that powers the compressor.

The functionality of the selected device will depend on the quality of these parts. The design of the compressor is usually simple and the device is driven by a motor. Today, reciprocating compressors, which are much more convenient than diaphragm ones, are more popular.

In turn, they are of two types: stationary (they are usually used at car services, they are also often used in order to slightly lower the wheels of SUVs while driving off-road), and portable (they are connected to the car, if necessary, through a cigarette lighter or to the battery itself ).

The design of an automobile compressor and its varieties

There are two types of compressors on sale today:

Reciprocating.
Membrane.

The piston compressor consists of a small piston and a special compression chamber. Outwardly, it is very similar to a device of a different type, but at the same time it has a completely different filling. One of the most important factors to look out for when buying is the type of material from which the piston itself is made.

To save money, most manufacturers use conventional galvanizing instead of high-strength alloy steel in their work. Many make some parts of the device from plastic, which greatly reduces the wear resistance of the compressor and its durability.

Therefore, the wear of such a device can come very quickly and there is no way to repair it. Such products are popular due to their relatively low cost, but it is better to save money by simply buying a better device.

Pros of using:

The device can be operated regardless of the ambient temperature and season.
His high power(more than 8 atmospheres).

Disadvantages:

It is impossible to change parts for it, since the piston cannot be repaired.
If the compressor is actively used, overheating is possible, so the device must be given time to cool down periodically.

The design of the membrane compressor is somewhat different. During its operation, air enters the tire due to its injection using a membrane sheet. The mode of its movement is reciprocating and there are no parts in the device that rub during operation.

Therefore, such compressors break down much less often and, if necessary, a damaged membrane can be replaced without any problems. If desired, each car owner can assemble a homemade membrane compressor, which in performance will not be inferior to the purchased unit.

Very reliable, low risk of breakage.
To be repaired if necessary.

Its power is much lower than that of a piston.
Do not use the device at low temperatures.

In order for the purchase to bring maximum pleasure, and the device itself performs all the functions assigned to it, you need to take a responsible attitude to the choice. It is imperative to study specifications of each compressor and choose the one that will work as efficiently as possible and will have more advantages than disadvantages.

Principle of operation

Automotive compressors have the following indicators:

Their performance.
The pressure that they are capable of pumping.
Pressure gauge.

Pressure. When buying a compressor, many car owners pay attention solely to the maximum pressure that it can deliver. You need to understand that many unscrupulous manufacturers can deliberately overestimate the characteristics. If a pressure of more than 8 atmospheres is indicated on the device, this is unreliable information.

Performance. Compressor capacity can be measured in liters / minute. Therefore, when buying, you need to take into account this parameter in terms of tire diameter. For large tires, you will need to buy a compressor that is capable of pumping about 70 liters; for small tires, a device with lower performance will be sufficient.

Food method. By this parameter, all compressors can be divided into several types:

They work from a cigarette lighter (such devices are suitable for inflating small tires, since they have very little power).
From car battery(have good power and are preferred). When buying, the kit necessarily includes special adapters and clips to make it easier to connect to the battery. The vehicle engine must be started during the tire inflation process, otherwise the result of the work will not be very high quality.
From the mains (they can be additionally charged, but at the same time the charge may not be more than 3 wheels, and then you will need to charge the device again).

Pressure gauge. It must be accurate to exclude the possibility of any error. All pressure gauges are divided into classes in accordance with the error that is permissible for them. Therefore, when choosing, it is advisable to focus on this indicator and purchase a device with a minimum value. They all fall into two groups:

With arrows (equipped with several scales at once, which greatly complicates the process of reading information during operation).
Digital (since, as the wheel is inflated, the device creates a certain vibration, so the arrows can jump, in this case it is more expedient to use a digital compressor). This device gives information to the nearest hundredths. The advantage of this type of pressure gauge is also the ability to limit the pressure, and after inflating the wheel to a certain level, the device will turn itself off.

After purchasing the device, you can go to a service station and check the accuracy of the pressure gauge to be sure that it gives reliable information.

Compressor selection

To make sure that the purchase is of high quality, you need to conduct a careful visual inspection compressor... Verified manufacturers mark the body and all hoses accordingly, the information on the stamp can be easily read.

The appearance of the device will inspire reliability, and the materials from which the compressor is made will be durable. When buying, you need to pay attention to:

The performance of the selected model.
Compressor continuous running time.
For what size of tires this device is suitable.
How high is the pressure it can pump into an inflated tire.
The length of the wire and hose (so that it is convenient to reach each wheel).

The plastic housing of the compressor can become unusable very soon, so it is preferable to choose a device with a metal housing. If the choice nevertheless fell on a plastic one, it must necessarily be non-flammable, resistant to mechanical damage and resistant to sudden temperature changes.

The same requirements are set for hoses, this is a very important part of the system, so it is better if they are made of high quality rubber. Its main function is to transmit high pressure, therefore, the failure of this part of the compressor can cause a lot of inconvenience to the car owner.

The modern market presents many models of compressors. They can be used not only for inflating tires, but also for other purposes:

For purging.
In the process of applying anti-corrosion compounds to the body.
For applying a primer.
To use it to remove dirt and grease from the engine.
For inflating flat tires.
In the process of working with pneumatic tools and a wrench.

Many manufacturers are equipping car compressors with additional features to expand their range of applications and make the process of use easier and more convenient. Often car owners do not pay attention to additional options but sometimes they can be very useful.

Here is some of them:

Automatic shutdown function - if the device is equipped with a special temperature sensor, it can turn off when the compressor overheats. Most devices turn off if the wheel is inflated to a certain pressure.

Some manufacturers have equipped the compressor with a special valve that is responsible for bleeding air.

Air evacuation- will be a great advantage if you need to roll up air mattresses, etc. An always useful function is the built-in flashlight, which greatly facilitates work in the dark. Some of the adapters that come with your compressor will be very useful.

Pumps from the last century, which had to be worked by hand, are already gone. More relevant today modern devices... These are electric car compressors. Even a fragile girl can handle them. How to choose the right ones what they are, how the owners speak about them - let's try to answer these difficult questions.

How an auto compressor works

The device of most models is generally universal. They consist of an engine, a cylinder and a pressure gauge. These nodes are considered basic, and the operation of the product depends on how high-quality they are.

Varieties of car compressors

Today there are only 2 types of tire inflation devices.

This equipment is of the piston and diaphragm type. What to prefer, considering that you need an automobile compressor from the cigarette lighter?

Piston pump

So, a piston-type device is equipped with its own chamber and piston. The system of this pump is analogous to the engine internal combustion... Yes, and appearance it looks a lot like a motor. But there are a lot of differences in the internal equipment. In this case, the quality of the materials and the degree of processing of the piston and chamber are important.

Ideally, a steel connecting rod is securely attached to a shiny metal shaft. However, most manufacturers, in order to save money, use not alloyed, but the most ordinary steel, or they make these assemblies from plastic. The overall quality is often lame. Such devices wear out quickly, and it is almost impossible to repair them.

However, if you buy a more expensive model, it will work very well. Such a product can serve for a very long time if not subjected to significant stress and properly operated.

Motorists are very positive about devices with a Teflon ring on the piston. Here, among other fairly high characteristics, a longer service life can be observed. And the device itself practically does not require any maintenance.

Yes, such a car works from a cigarette lighter, but it can also be connected directly to the battery.

Membrane equipment

These have a radically different design and operating principle.

For swapping, a special canvas is used here. With the help of reciprocating movements, it pumps air.

Motorists are not very flattering about these pumps. There are some problems with them in winter period... When the temperature is low enough, the membrane becomes hard and then breaks under stress. These compressors are not recommended.

Although such equipment is much less likely to fail. There are no rubbing parts here. Of the moving parts, only bearings are here. And the maintainability is much higher than that of the piston "brothers", and the membrane is easy to replace.

The disadvantages include low pumping speed and high price. In addition, it is very difficult to find a membrane compressor for an automobile from a cigarette lighter on sale.

How to choose a quality compressor

When choosing this device, you should pay close attention to a variety of factors.

We'll go over them in order. Among important parameters is the level of pressure that the device can give out. The connection method, the accuracy of the measuring device, and the scale are also important.

Pressure

Giving an answer to the question of which car compressor in the cigarette lighter is better, most turn Special attention to the maximum pressure that the unit is capable of. This is not entirely correct. Many manufacturers of these products deliberately overestimate the performance. On most models, the manufacturer indicates a maximum pressure level of 20 atmospheres. This is simply unrealistic for a device of this size and power. The maximum limit is 8 atmospheres.

Performance

This characteristic is measured in liters per minute.

Therefore, if you choose an automobile compressor from a cigarette lighter, you must take this into account. The fit of the tire is also important. For example, for a 14-inch tire, a pump with a capacity of up to 40 liters will suffice. If the tire has larger size, then more efficient equipment is needed.

Here, the manufacturer often indicates the volume, without specifically mentioning whether it is an ordinary volume or under pressure. The first indicator is often interesting. It is very important to clarify this before purchasing.

Compressor power

There are also two available options: this is a battery equipment or a compressor for car tires from the cigarette lighter. In the first case, the device is simply charged. It is equipped with a built-in battery, but the charge is only enough for 2, maximum - for 3 wheels.

The second option is much more preferable.

Such a pump can be connected either directly to the cigarette lighter, or using terminals directly to the battery. The device for the cigarette lighter has less power, but has the advantage of being connected.

Pressure gauge accuracy

Here, devices are also divided into two types. These are instruments with a dial or digital pressure gauge.

If we talk about accuracy, then this is very important characteristic... Errors should be as small as possible. There are several pressure gauges of different accuracy classes. So, the best is the device with a small number of errors.

Speaking of accuracy, the best compressor for car tires is from a cigarette lighter with pressure. The thing is that the pump vibrates very much during operation. On an ordinary pointer indicator, the arrow jumps and twitches. In addition, there are two scales on the dial. These are bar and psi, which greatly overloads the dial.

Compressors and brands

Let's try to highlight a few major brands. Let's look at the characteristics of the equipment. Let's draw some conclusions.

Zeus ZAC201

This device is fully suitable for working with car tires. The pressure that this device creates is 10 atmospheres. The unit capacity is up to 30 l / min. This figure allows the pump to run continuously for half an hour. Owners have been using car compressors from the Zeus ZAC201 cigarette lighter for several years. There are no drawbacks to devices from this manufacturer. The compressor comes with a variety of attachments.

So, you can swing not only the wheels of the car, but also much more. The device is designed to be powered from a car cigarette lighter. The body of the device is made of metal and can easily withstand pressure. Pressure control is carried out using a built-in pressure gauge. The model is equipped with an LED flashlight that can operate in two modes.

The pump is a piston type with a power of 120 watts. In order to be able to use the device as safely as possible, it is equipped with a fuse, as well as a drain valve. Also, manufacturers have provided emergency indication. The cord is 3 m long, and the length of the air hose is 1 m. This is quite enough for comfortable use of the device.

Those who already use car compressors from the Zeus ZAC201 cigarette lighter, the reviews are generally positive. The pressure is sufficient to inflate the tire to its normal value. Overall, it is a durable device. For many, it has been working effectively for several years.

"Continental"

This renowned manufacturer automotive rubber also manufactures pumps. The compressor of this brand is a small plastic box. It gives out pressure up to 8 atmospheres. The pneumatic hose is 70 cm long and the power cord is 3.5 m long. The device is connected to the cigarette lighter. At its price, an automobile compressor from the Continental cigarette lighter will be an excellent purchase. And the compact body of the device does not take up much space in the trunk. Although the pressure level is not too high.

Compressor "Berkut R15"

This is a product domestic manufacturer... Its voltage is 12 V, the compressor is connected to the cigarette lighter. The maximum possible pressure of this equipment is 10 atm. The performance is quite high for devices of this type - 40 liters of air pass through the pump in one minute. The device can work continuously for 30 minutes. Its price is about 2000 rubles.

In the delivery set you will find a compressor, as well as a set with adapters for pumping balls and other rubber products. There is also an adapter for connecting the device to the car battery.

The device is equipped with a pressure relief valve for safe operation.

It is located at the end of the pneumatic hose. The cord that connects to the cigarette lighter is made taking into account the fact that it can be used outside in the cold.

Among the advantages are noted: high build quality and excellent performance. Among the shortcomings, the low accuracy of the manometer was noted. This is a fairly powerful and quiet compressor, which is suitable for both passenger cars and off-road.

"Jock 950LED"

Here, too, the maximum pressure is 10 atmospheres. Opening hours are also 30 minutes. Compressor capacity - 40 l / min. The device is completed with a set of adapters for balls, as well as a handy bag. The pressure gauge can be found on the housing. The hose is not removable. For convenient storage of the device, the manufacturer has equipped the case with special grooves. For ease of use, the place where the fitting is pressed into the hose is hidden by means of There is also a pressure relief valve.

To protect the on-board network of your car from overloads, the device is equipped with a fuse. Of the advantages of this device, only: a built-in flashlight and a comfortable safety valve are noted. Among the disadvantages is poor performance, not specified switches, manometer error. Although at its affordable price of 1450 rubles. is a good buy.

Outcomes

In general, today the choice of such equipment is quite large. Many devices have excellent power and performance characteristics. They do their job well, they are compact and many of the devices are versatile. You can purchase an automobile compressor from a cigarette lighter. The price of these devices is on average low, and hand swinging wheels is no longer very popular today.

Recently, the tire inflation compressor has become more than popular among motorists. He replaced the pump not so long ago. The main advantage of compressors is that tire inflation takes a little time and does not require any force. But it is advisable to first figure out how to use the compressor correctly in order to get the most out of it and not reduce its working life.

Compressors are piston and diaphragm. They work differently, but they perform the same task.

Membranes are cheaper, but generally they are not recommended for Russian conditions, since the membrane is made of rubber, and in winter conditions and low temperatures, it cracks, allowing air to pass through. Ultimately, such an electric pump can only be thrown away. The resource of piston analogs is much longer.

Instructions for use

In fact, using a car compressor is not at all difficult; all you need to do is know the whole process and do not forget the recommendations.

Tire inflation process

The compressor has a power cable. If it is a cheap model, then it will have a cigarette lighter socket. On more expensive devices, this wire is bifurcated, with terminals for connecting to battery... This increases the power. Of course, when it comes to a high-quality battery. You can choose one at http://www.rimir.by, where a wide range of batteries is presented.

First you need to connect a wire so that the electric pump has something to power from.
Then you need to screw the compressor hose tightly to the wheel nipple. At this stage, you can see the pressure in the tires on the pressure gauge and understand how much it needs to be raised.
Now is the last stage. It is necessary to switch the device switch to operating mode. Tire inflation starts. The main thing here is not to overdo it and pump up the wheel to the required volume - it can be tracked on the pressure gauge.

Also, do not forget about the very important rule exploitation. It is necessary to inflate the wheels or simply check the tire pressure in a place where the conditions are the same as when operating the car. Also, the tires should not be cold after the ride.

In order for the tires to return to normal temperature, it is necessary to wait about half an hour after use, depending on the weather. If you do not follow this rule, then the pressure will be incorrect, and besides, it may differ in each wheel. If the wheels are pumped up in the cold, then when the temperature changes to positive pressure, it will rise, and this can lead to sad consequences.

Features of operation of different compressors

If you have a membrane compressor, then you must adhere to the following recommendations:

It does not need to be heavily overloaded, otherwise the device may fail due to excessive loads.
It shouldn't work for more than 15 minutes.
The most favorable conditions for this type of device are regions with a warm climate.

In the cold, they can fail. As mentioned above, this is due to the fact that the rubber membrane begins to harden at low temperatures and then crack. The protective layer of the wires also suffers, which is why the wires themselves short-circuit. Ultimately, this blows the fuse in the cigarette lighter.

Reciprocating compressors have no such problems. They work without problems in any conditions, both in frost and heat. However, it is also impossible to operate them without interruptions, since a large load occurs due to the piston.

In fact, the device of compressors is the simplest, so everyone can understand how it works and learn how to use it correctly. You just need to learn about the main points and listen to the recommendations, then the device will last a long time and will not cause problems.
