The automobile compressor has replaced the hand and foot pump for inflating tires. The most pleasant advantage of this device is that it is fully automatic and in order to inflate the tire you do not need to use physical effort. It is convenient to have a compressor always at hand, no matter where you are. However, it happens that it fails and then repairs may be required.
Why is a compressor today a driver's essential item? After all, there are so many service stations and tire shops around where you can pump up tires and, if necessary, make other repairs. It's simple. A tire can go flat anywhere, for example, in a mountainous area or in a suburban area, far outside the city - there is not always a specialized workshop nearby. And then, it’s better not to lose control of the situation and fix the problem yourself, quickly, without unnecessary expenses and hassle.
Causes of compressor failure
The most common cause of failure car compressor is a banal fuse blown. The fuse of the unit or the one located on the wire may burn out. This type of damage is not serious and can be repaired very quickly. Moreover, spare parts for repairs can be bought in almost every store, for example here exist.ua.
Also, one of the options in which the compressor fails involves damage to the power cord. It is very easy to identify this problem. It is enough to visually examine the wire and find the place of the tear or break. This problem can also be dealt with easily and quickly. Surely every man has changed the plug on the iron cord.
There are also more serious reasons for the failure of automobile compressors. For example, if the winding of an electric motor or vibration coil catches fire, it is rarely possible to save the patient.
If you find that the compressor turns on, but does not give the desired effect, 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 car compressor than to carry out repairs and buy new spare parts.
But most often the problem is not acute and requires minor intervention, replacement of a spare part or component. Usually this is a leaky hose, a valve that fits on the wheel nipple, a rubber gasket ring, brushes, and nozzles.
Features of auto compressors
Due to the fact that the car compressor comes with various attachments, it can be used not only for inflating car tires, but also for balls, inflatable boats, bicycles, etc. That is, a compressor plus nozzles is a universal device that allows you to solve several problems at once.
In order to repair a compressor, it is important to know its structure and features. So, each representative of automotive compressors is equipped with:
- Electric motor;
- Pressure gauge;
- Cylinder;
- Piston;
- Other components (cables, brushes, gaskets, nipples, nozzles).
According to their design, they distinguish between membrane and piston compressors. The principle of operation of a membrane compressor is to compress gas due to the fact that forward movements membranes reduce the volume of the chamber. The membrane, sandwiched between the cylinder and the lid, begins to vibrate and acts like a piston.
Piston compressors are equipped with a special piston, which, when connected to the crankshaft, sucks in air masses. They are much more popular among car enthusiasts.
To ensure maximum pressure, piston compressors operate in stepped mode. Yes, compressed air mass is distilled from one cylinder to another via a cooling tube. The volume of one cylinder is intentionally larger than the second, but the latter pressurizes the air, increasing the efficiency of the device.
Weaknesses of a membrane compressor
The weakest part of membrane compressors is the membrane. If foreign particles accumulate in the gas cavity of the unit. Important aspects work with such a compressor are:
- Keeping the block clean.
- Prevents moisture and dirt from entering the membrane block.
- Timely replacement of spare parts (membrane, gas valve, pressure limiter).
Weaknesses of a piston compressor
The most common problems with a piston compressor are:
- The compressor refuses to start;
- There is no release of air into the receiver, although the motor is running;
- Knocks out fuses;
- Air pressure drops sharply;
- Incorrect operation of the thermal protection circuit breaker;
- The humidity of the air pumped by the compressor is increased;
- The motor operates at high vibrations;
- The connection between the hose and the nozzle is worn out and the air is leaking.
What to do if the compressor does not start
If the device refuses to work, you need to perform certain diagnostic actions using an indicator screwdriver. We examine whether there is a phase and whether voltage is supplied. If everything is in order with the phase, proceed to checking the fuses, perhaps they have melted. If this is the case, then simply replace the fuse. It is important to remember that when making repairs, the installed spare parts must be of equal value.
After replacement, everything should work, however, it happens that the fuse blows again. This suggests the possibility short circuit. Repair needed. Call the diagram. When the faulty parts are installed, replace them with new, similar parts.
Compressor failure may be due to a failure in the settings of the pressure control relay. To diagnose this problem, do the following: bleed the air and restart the compressor. If you hear the sound of the motor running, reset the settings, the motor is not functioning, you need to replace it. Remember that when the thermal protection is working intensively, it is necessary to cool the engine for at least 20 minutes, this will normalize the operation of the compressor.
Particular attention is paid to the situation when, when the device is turned on, both the fuse and the thermal protection fail. If the only problem is that the installed fuse is not designed for the operating power of the unit, then the repair comes down to a simple replacement of the spare part. But if the relay fails, do not try to get into it yourself. In order to receive qualified repairs, go to the service center.
In a situation where the piston is faulty, you need to disassemble the device. When making repairs, release the air, clean the valve from dirty formations; if the pressure continues to drop, the problem is in the valve and it needs to be replaced.
Where to get spare parts for compressor repair
With such an abundance of auto stores and places where components are sold, your head can simply spin. Where can I buy spare parts for repairs or new attachments? In principle, there is no big difference in the places where spare parts are sold. It's a matter of convenience for everyone. Some people go to a specialized store, some for meal, while others find it convenient and profitable to order spare parts via the Internet. The taste and color, as they say.
The main thing is not to run into a fake when making a purchase. Original spare parts are the key to their long service life. Ask for a certificate or warranty card when purchasing new parts for repairing compressors from the seller.
In general, compressor repair is simple and can be done without the appropriate experience or qualifications. Although it is better to prevent breakdowns in advance by simply caring for the equipment.
Not really
Air compressor– a mechanism that drives pneumatic devices, often used in screwdrivers, drills, etc. Moreover, this indispensable tool for summer residents - processing, spraying plants, pruning trees, whitewashing - these are just some of the capabilities of this unit. The compressor also inflates tires and is used to blow debris out of hard to reach places Oh. Scroll possible application The machinery on the farm is very large. If you have it, then, of course, you have already appreciated its usefulness. But, as with any technical device, it is possible that the compressor does not turn on. Let's look at the likely reasons why this happens and how to eliminate them.
Design domestic compressor quite complicated, classic scheme devices are being added additional elements, for example, for air humidification, automation of work. This makes it difficult to find the reason why the unit does not start. The fact that the compressor does not turn on can be influenced by external factors and mechanism failures. External factors include low temperature in the room where the unit is installed and insufficient network voltage. Let's talk in more detail about technical problems.
The system supercharger does not start - one of possible reasons. The engine does not turn on if there is no power. You need to check the connection to the outlet, the presence of “zero” and “phase” indicator screwdriver. If everything is in order with this, then we check the condition of the compressor fuses. If there are burnt out ones, they are replaced with elements of a similar model. After this, we try to start the installation again, if this again fails and the fuses “burn out” again - the problem lies in a short circuit at the input of the circuit, it must be eliminated. If everything is in order with the fuses, we check the relay.
Its malfunction is the second possible reason for the air compressor not turning on. The pressure control switch may not work due to burnout of any part of it, or due to incorrect level settings. In the latter case, we release the gas from the cylinder, start the supercharger, and if the engine starts working, then we reconfigure. If not, then you need to repair the relay.
The compressor does not turn on; if the piston system overheats, the thermal protection circuit breaker turns on. You need to give the heater time to cool down, at least 15 minutes.
When the engine hums but does not start, the problems lie either in undervoltage in the network (normally it should be 220V), or problems with high pressure in the receiver. If the voltage matches the desired value, then we bring the pressure back to normal. To do this, turn the automatic switch to “off”, and after 15 seconds to “auto”. It didn’t help - check to see if the control valve is clogged. If everything is fine with it, but the compressor still does not turn on, you need to repair the pressure control relay again. It is best to carry out repairs in specialized centers.
The reason the device does not start may be that when it is turned on, the thermal protection is triggered or the fuse is blown. Let us explain why this happens. The fuse does not match the rated power specified in the documentation, or the network is overloaded. To eliminate the problem, free the network from excess load and replace the fuses with ones that meet the requirements.
The compressor may not turn on due to more serious problems - for example, a broken voltage relay. If there is a suspicion that this is the reason, then it is worth connecting the motor bypassing this circuit element. If it starts without a relay, then that is the problem. Voltage relay repairs are carried out at service centers.
Another one serious reason the unit is not in working condition – the bypass valve is broken. It is also better to fix it at technical support sites for the device.
If all the problems listed above are not found, conduct a visual inspection of all parts of the device; perhaps some of them are cracked, damaged or broken, then it needs to be replaced, even if the damage is minor.
Summarizing all of the above, we can distinguish four main directions for searching for the problem:
electrical problems;
incorrect settings;
part failure;
pollution.
To avoid problems with the operation of the mechanism, you need to follow a number of simple recommendations:
1. Check the oil level regularly, use what is specified in the technical data sheet. After filling, let the compressor run for a few minutes. Idling so that the oil spreads well. It is replaced every 500 hours of operation of the unit.
2. Clean the air inlet filter frequently.
3. Every 16 hours of operation, drain the condensate from the receiver.
4. After work, turn off the power supply and “bleed” the air from the high pressure system.
5. The device must be grounded.
If all these operations are performed from the moment you purchase the unit, then there will be no reason to worry about its operation for a very long time. And to troubleshoot problems, it is better to contact specialists, especially if it concerns the replacement or repair of main parts of the compressor, such as relays or valves.
A car compressor is a device that has significantly simplified the process of inflating tires, which was traditionally done using a hand or foot pump. This unit can operate in automatic mode, has a compact size, and inflating tires with its help does not require the use of physical effort. Although the auto compressor is no different complex design, some of its components may fail over time. To repair a device yourself, you need to have an idea of how it works and on what principle it works.
Compressors for inflating wheels are of membrane type and piston type. Both types of devices are designed for compressing air and differ from each other not only in design, but also in their operating principle.
Membrane devices
If you look at the design of a membrane-type automobile compressor, you can understand that the main element of the unit with which air is compressed is is a membrane. It is made either of rubber or metal.
The membrane autocompressor consists of the following elements:
- an electric motor that drives the compressor unit drive;
- compression chamber on which 2 valves are installed;
- rubber, polymer or metal membrane located in the compression chamber;
- a rod connecting the piston to the membrane;
- a piston connected to a rod and connecting rod;
- connecting rod and crank;
- crankcase, which houses the crank mechanism (crank mechanism).
Auto compressor works according to the following principle. The crank converts the rotation of the drive shaft into reciprocating movements of the connecting rod. The one connected to the piston sets it in motion. The piston, moving up and down, sets the membrane in motion with the help of a rod. Moving down, the membrane creates a vacuum in the compression chamber, due to which the intake valve opens. When the latter is opened, the chamber is filled with air. Moving upward, the membrane provokes the closure 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 downward, a vacuum is again created in the chamber, from which the outlet valve closes and the inlet valve opens. Next, 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 device does not contain any foreign impurities. In addition, in membrane units, air leakage through seals or piston rings is eliminated, which has a positive effect on the performance of the auto compressor.
Piston units
In piston-type tire inflators The main part is the piston.
Consists of this type automobile pump from the following components and parts:
- an electric motor driving the device drive;
- compression chambers (cylinder) with intake and exhaust valves;
- air filter;
- a piston having an o-ring;
- A crankshaft, consisting of a connecting rod and a crank;
- crankcase in which the crankshaft is located;
- a pressure gauge, which is designed to monitor the tire pressure level and can be installed on a cylinder or hose.
The device works as follows. The crankshaft is driven either by a gear transmission or a direct drive. He transforms rotational movements The drive shaft is reciprocating, which causes the piston to move up and down. The piston, moving downwards, creates a vacuum in the cylinder, as a result of which the intake valve opens. The 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 is reached in the compression chamber, the exhaust valve opens, through which air exits the device. Next, as the piston moves downward, the exhaust valve closes and the intake valve opens, and the cycle repeats.
Common problems with reciprocating compressors
Since the design of membrane autocompressors differs significantly from the design of piston compressors, some breakdowns of these devices will be typical only for certain type units.
The most common malfunctions of piston auto compressors that you can fix yourself include the following:
- the device does not turn on;
- the engine of the unit is running, but does not pump air;
- the device does not create the necessary pressure;
- The compressor switches off spontaneously.
The device does not turn on
Compressors for inflating tires have power cable(s) for connection to a 12 V power source. 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 you should check the power cables for damage. They can be “ringed” by a 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 should be replaced.
Advice! Most often, owners of Tornado car pumps encounter 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, the 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 device.
The unit's engine is running, but it is not pumping air.
If, when you turn on the device, you hear the sound of a running engine, but no air comes out of the hose, then in order to diagnose the unit, you'll have to disassemble 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 common cause that the device does not download. To eliminate the malfunction, it is necessary to remove the seal and the disk with the valve from the piston head.
Under the valve there is a small sealing ring which may wear out over time. When it wears out, the valve does not fit tightly and allows air to pass through. As a result, compression of the latter does not occur. Also, sometimes this ring can move from its place seat. If this happens, the valve will also not be able to close. Often the valve plate simply breaks. In this case, it must be replaced. This part, like other spare parts, can be purchased in online stores.
Another reason that the device does not pump may be loose screw, with which the crank is secured to the engine shaft.
If the screw is unscrewed, the motor shaft will rotate, but the crankshaft will remain motionless.
The device does not create the necessary 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, preventing a good fit. To repair a tire inflation compressor, you will need disassemble the piston head and thoroughly clean all parts from accumulated dirt.
Sometimes insufficient air pressure at the inlet from the unit may be due to O-ring deformation, dressed on the piston.
To remove the piston, you need to remove the sleeve jacket and the sleeve itself.
The piston O-ring may become deformed due to overheating of the unit. To straighten the ring, it must first be softened. For this purpose, you can use either solvent 646 or WD-40 fluid. After the ring becomes soft and pliable, it should be leveled, the sleeve and jacket should be put in place. You can check whether the piston moves correctly in the sleeve by turning the engine shaft.
The compressor turns off spontaneously
Some models of auto compressors have overheat protection. For this reason, the device can turn off spontaneously, for example, when long work. But overheating of the unit can also be caused due to manufacturing defects, especially in inexpensive models. There is a flaw in poor fit of the device sleeve to the shirt. In this case, heat removal from the piston block is reduced and, as a result, the piston head and engine overheat.
IN in this case Repairing a car pump will consist of 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 an ordinary beer can. You need to wrap the sleeve with aluminum and insert it tightly into the shirt. After these steps, heat transfer will improve and the compressor will no longer turn off spontaneously.
Malfunctions of membrane autocompressors
Diaphragm autocompressors break down extremely rarely. Although they are characterized by some breakdowns inherent in piston devices: damage power cable or the fuse in the plug used to connect to the cigarette lighter has blown.
But still, the main element of the tire inflator that can fail is membrane. Most often, it is made of rubber or other plastic material, which at low temperatures hardens and becomes inelastic. If such an autocompressor is turned on at low ambient temperatures, the membrane will simply rupture. In this case, car compressor repair of this type will consist of replacing the membrane.
How to change the pressure gauge in a compressor
Replacing the pressure gauge on a car compressor will be necessary if it fails. The measuring device can be installed separately from the unit, on a 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 make a mistake when buying a new pressure gauge, it is recommended to take it with you and ask the seller to select an analogue.
In some cases, choosing the right device can be difficult. It’s easy to get out of this situation: buy 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 bleed a little air from the wheel, you just need to press the pressure gauge button.
Modern compressor equipment is considered very reliable and durable. Thanks to developments in metallurgy, composite materials, electronics, many mechanisms have undergone changes in better side. The same thing happened with compressors. Although the basic units remain the same, the changes are quite obvious.
Compressors are becoming more compact, without losing their former power. Parts are less likely to fail thanks to modern materials, from which they were made. Lubricating fluids are becoming richer in additives, which also extend the life of spare parts. You can increasingly see high-tech control panels - with their help it has become possible to easily start and stop cars. In addition, the remote control can provide all the information about the number of hours worked, the compressed medium produced, and even warn about possible future problems. It became possible to diagnose the unit without disassembling it.
Household compressors are also stuffed with all sorts of sensors, although they cannot yet boast of having such an informative remote control. This is what can create some problems. For example, a temperature sensor, sensing minor deviations from the norm in temperature indicators, can simply signal that proper operation, which causes the engine to stop. In this case, it is quite difficult to figure out what exactly the problem is.
During operation compressor equipment Various breakdowns and malfunctions may occur. Consumers often encounter this problem when the compressor does not gain pressure. Not every owner of compressor equipment knows what to do in such cases.
Typically, such a problem occurs some time after the equipment has been put into operation. At one point, the compressor simply refuses to gain its required pressure. The reason for this could be a variety of circumstances. First of all, you need to check whether the settings of the pressure regulator have gone wrong. After making sure that the settings have not been violated, you can begin to carefully visual inspection the entire compressor. You should look at the threaded connections of the pipes at the inlet to the receiver and at the outlet of the cylinder - vibration could weaken these critical components and it is possible that this is the reason for the lack of pressure. 
Also, do not forget about the screw-in pressure gauge and relief valve - they can also begin to poison from under them for the same reason. The relief valve itself may fail. overpressure– stop closing tightly. Such problems can be easily fixed. In this case, you just need to take the appropriate wrench and tighten the couplings tightly. In some cases, it may be necessary to replace the gasket or additional winding. If threaded connections at first glance, they are tightly screwed in and there are no obvious signs of air leaking through them, but the compressor does not gain pressure, you can use a soap solution even when the unit is turned on paint brush lubricate all connections with it. If there is still a fistula, it will be immediately visible - bubbles will immediately begin to form at the site of the etching. This method is very convenient, since due to the noise during operation of the compressor, it is not possible to hear the escaping air.
You can also soak the soapy liquid under the cylinder head and under the cylinder itself. So etching from these hard-to-reach places turns out to be a very common cause of under-rated pressure and improper operation of the compressor. Fixing such a breakdown is a little more difficult and it is better to seek help from a specialist. But, if you still decide to repair it yourself, then first you will need to remove plastic casing, if available. Next, sequentially unscrew the nuts that tighten the cylinder head to the compressor housing. It happens that the nut does not give in and instead a stud begins to unscrew from the body - this is not a problem, but when reseating the cylinder, it is desirable that the studs are screwed in in their places, and everything is tightened with nuts. Once the cylinder head has been carefully lifted, it is possible to inspect the gasket. A possible defect will be immediately noticeable - the gasket will have a rupture in the wall and the reason for this may be poorly tightened previously mentioned studs and nuts. This can only be corrected by replacing the gasket - some models are equipped with spare sets of gaskets, you can also purchase them in specialized stores or make them yourself. To do this, you will need a piece of aluminum sheet with a thickness of 0.2 -0.15 mm. You need to cut out a new gasket using scissors according to the unsuitable sample, and assemble everything as it was originally. Tighten the nuts evenly, crosswise, being careful not to strip the threads. Afterwards, you should start the compressor and again lubricate all possible places where air has leaked to make sure that the defect has been corrected.
The reason that the compressor does not pump up the required pressure can also be worn out compression rings - this is natural cause for piston compressors. The rings and piston have installed resource work, after which they must be replaced with new products. Otherwise, this becomes an inevitable consequence of a loss of power and is primarily manifested by a lack of pressure.
Loose fit and valve breakage is one of the fairly common problems of piston machines, and such a defect is difficult to determine without disassembling it. Signs of this may include excessive overheating of the compressor, a significant increase in the period of time for pressure build-up in the receiver, and sometimes the inability of the unit to reach its rated pressure. In this case, only replacing the broken valve with a new one will help.
In addition, over time, the power of the electric motor also fades, which can also have a bad effect on the final result - pressure. Few people pay attention air filter at the entrance and this causes various breakdowns. Dusty air deposits carbon deposits on the piston group, which should not happen in the compressor, since this is not an internal combustion engine. Carbon deposits are also deposited on the rings - this leads to an increase in oil consumption and its release into the receiver, and then into the pneumatic line. The temperature rises, the valves begin to overheat, and then break. A dusty compression environment reduces the service life of the main elements of the compressor piston, rings, and cylinder.
Failure to follow operating instructions, including untimely replacement of filters and other replacement parts, can lead to a lack of pressure and even serious damage. That is why it is necessary to comply with all requirements for operating the compressor, as well as carry out regular maintenance. Maintenance and replacement of necessary parts.
