Do-it-yourself tornado autocompressor repair

After a long work, the tornado compressor did not break much.
At the bottom of the money 🙂 click - MORE
I began to pump up summer car tires, and instead of the usual rumble, I heard the clanging of metal and then the idling of just the electric motor of my tornado pump.

After disassembling its piston part, it was found that the crankshaft was loosened, one part of it broke off from this and the engine shaft began to spin at idle.
After the repair of the tornado pump, it came to life a little, how long time will tell!

A TORNADO AC580 automobile compressor with a declared malfunction was received for repair - something is not in contact somewhere, in general, it does not work.

By the way, compressors are used not only in automobile pumps. For example, Delaton produces a mind-boggling amount of all kinds of compressor equipment, repairs and maintains it. There is even a whole division of professional compressor units that can be used in a variety of areas of activity: this is cleaning parts from dust with the help of compressors (blowing dust), this is spraying paint under pressure from a compressor, this is a banal inflating birthday balloons. I do not think, of course, that you will need an industrial compressor to inflate birthday balloons, but for other tasks, you may well need a compressor. Let's continue, otherwise I digress.

We connect 12V, turn it on - it really does not turn on. We will repair. First, we disassemble the connector that is inserted into the cigarette lighter.

Unscrew the top:

Here is the error. One of the contacts - minus - is completely torn off. This once again confirms the simple truth that electronics is the science of contacts. Solder it in place.

We connect 12 volts. Turn on. Shakes. With a happy smile, we go to inflate the wheels of our car.

By the way, did you know that there are two types of compressors: rotary (screw) and piston. As I understand it, the automotive compressor that was discussed in this article belongs to the piston group. There is also some intermediate type - a membrane one, but this, as I understand it, is one of the varieties of a piston compressor. In general, if you want to more fully immerse yourself in this topic and understand how screw compressors differ from piston compressors, go to Yandex or Google and read. Reading develops the mind! (With).

The car compressor has replaced the hand and foot pump for tire inflation. The most pleasant advantage of this device is that it is fully automated and no physical effort is required to inflate the wheel. It is 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 a compressor a must-have for a driver today? After all, there are so many service stations and tire shops around where you can pump up tires and, if necessary, make other repairs. Everything is simple. The wheel can be lowered anywhere, for example, in a mountainous area or in a summer cottage, far outside the city - there is not always a specialized workshop nearby. And then, it is better not to lose control over the situation and fix the problem yourself, quickly, without unnecessary expenses and hassle.

The most common cause of a car compressor failure is a banal blown fuse. The fuse of the unit or the one located on the wire may burn out. Such a breakdown is not serious and is very quickly eliminated. Moreover, spare parts for repairs can be bought in almost every store, for example here.

Also, one of the options in which the compressor fails involves damage to the power wire. Determining this problem is very simple. 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, for sure every man changed the plug on the iron wire.

There are more serious reasons for the inoperability of automotive compressors. For example, when a winding of an electric motor or a vibrating coil ignites, it is rarely possible to save a patient.

If you find that the compressor turns on, but does not give the desired action, that is, it does not pump air, look for a problem in the wear of the piston or the PTFE 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 acute and requires a little intervention, replacement of a spare part or component. Usually this is a leaky hose, a valve worn on the nipple of the wheel, a rubber ring-gasket, brushes, nozzles.

Due to the fact that the car compressor comes with various nozzles, it can be used not only for inflating car tires, but also for balls, inflatable boats, bicycles, etc. That is, the compressor plus nozzles is a universal device that allows you to solve several problems 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 with:

• Electric motor;
• pressure gauge;
• cylinder;
• piston;
• Other accessories (cables, brushes, gaskets, nipples, nozzles).

According to their device, diaphragm and piston compressors are distinguished.. The principle of operation of the membrane compressor is to compress the 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 cover, begins to oscillate 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 the highest pressure, reciprocating compressors operate in a stepped mode. So, the compressed air mass is distilled from one cylinder to another, through a cooling tube. The volume of one cylinder is intentionally larger than the second, but the latter compresses the air, increasing the efficiency of the device.

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

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

The most common piston compressor problems are:

• The compressor refuses to start;
• No air is released into the receiver, although the motor is running;
• Knocks out fuses;
• The air pressure drops sharply;
• Incorrect operation of the thermal protection machine;
• The humidity of the air pumped by the compressor is increased;
• The motor runs on high vibrations;
• The junction of the hose and nozzle is worn out and the air poisons.

If the device refuses to work, you need to perform certain diagnostic actions using an indicator screwdriver. We investigate whether there is a phase, and whether voltage is applied. If everything is in order with the phase, proceed to check the fuses, maybe they have melted. If this is the case, then just replace the fuse. It is important to remember that when making repairs, the installed spare parts must be equivalent.

After replacement, everything should work, however, it happens that the fuse blows again. This suggests a possible short circuit. Repair needed. Call the diagram. When the defective parts are installed, replace them with new, similar parts.

The failure of the compressor may be due to a failure in the settings of the pressure control switch. In order to diagnose this problem, do the following: bleed the air and start the compressor again. If you hear the sound of a running motor, reset the settings, the motor does not function, you need to replace it. Remember that during intensive operation of thermal protection, it is necessary to cool the motor for at least 20 minutes, this will normalize the operation of the compressor.

Particular attention deserves the situation when, when the device is turned on, both the fuse and 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 is out of order, do not try to climb there yourself. In order to get a qualified repair, go to the service.

In a situation where the piston is faulty, you need to disassemble the device. When making a repair, release the air, clean the valve from dirty formations, if the pressure continues to drop - the problem is in the valve, it needs to be replaced.

With such an abundance of car dealerships and places for the sale of components, your head can just go round and round. Where to buy repair parts or new nozzles. In principle, there is no big difference in the places of sale of spare parts. It's a matter of convenience for everyone. Someone goes to a specialized store, someone goes to meal, and someone finds 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 compressor repair parts from the seller.

In general, compressor repair is not difficult and can be done without the appropriate experience or qualifications. Although it is better to prevent damage in advance, simply by caring for the equipment.

The automobile Tornado compressor among inexpensive devices is in great demand. It is equipped with a productive pump, has a high pressure ceiling and is equipped with a long hose. The compressor uses components from Asian companies, and assembly production has been established in the United Arab Emirates and China.

Compressors Tornado

Tornado compressors are presented in several "weight" categories: AC 550, AC 580, AC 600, AC 700, etc. Compressors are sold in solid packaging and are well equipped. The kit even includes a waterproof cloth backpack with zippers, equipped with a carrying handle. Also included are three fittings for inflating a variety of inflatable products: balls, pools, boats, mattresses, etc. Automobile compressors can be equipped with both a quick-detachable inflation fitting and a more reliable screw-on one.

Tornado compressors of all modifications are quite powerful. Therefore, they have good performance in small sizes. Compressors easily reach a pressure of 7 kgf / cm2. For most car owners, two atmospheres (kgf / cm2) is enough.For example, the Tornado AC 580 compressor creates two atmospheres in 2.5 minutes, three atmospheres in four minutes. Model AC 600 pumps 35 liters of air per minute.

Operation features

Compressors are created according to the usual scheme. With good care, they can last for several years. However, there are enough complaints about them. Experts advise lubricating rubbing parts and mechanisms after purchase. Sometimes the units fail on the very first days of operation, it's good that dealers give a 1-2 year warranty. Another constructive disadvantage is that the screwing speed of the brass hose tip is slightly lower than the connection speed of the quick-release fitting. Therefore, there is a certain loss of air when disconnecting and attaching the hose to the car wheel.

The manufacturer proposes to connect compressors to the car's electrical network through the cigarette lighter socket. But in this case, it is necessary to take into account what current strength the fuses that protect the cigarette lighter can withstand in a particular car. If the compressor consumes current in excess of the allowable current of the cigarette lighter, drivers will have to be smart with the wires. In order not to burn the cigarette lighter and car wiring, it is more reliable to connect Tornado compressors with terminals directly to the battery.

The weakest point of the younger models is the pressure gauge. Surely many drivers will be puzzled by the rate of deflection of the pressure gauge needle. To find out the tire pressure value, you will have to wait until the arrow stops at a certain value. For example, the arrow “creeps” to the mark of two atmospheres half a minute after the pressure gauge is connected to the wheel valve. Owners of large vehicles with tire pressures up to five atmospheres will have to be even more patient.

Among the advantages, we highlight a high pressure ceiling, good performance, a long pump hose. The disadvantages include insufficient reliability, a shortish power wire, and a slow gauge. In general, the Tornado brand automobile compressor, due to its power, is able to cope with the wheels of light trucks, minibuses and SUVs. Inflates air mattresses and rubber boats very quickly.

Technical characteristics of Tornado compressors

It happens that the wheel of the car poisons a little (lowers) and it has to be pumped up. But here's the bad luck, when you connect the autocompressor, he worked a little and stalled or did not turn on at all. Here we will try to analyze the most common breakdowns and causes associated with the failure of autocompressors and eliminate them.

The first and most common reason, this is a blown fuse in the fuse box of the car or on the wire of the autocompressor, where it is often installed. This breakdown is one of the most frequent, but it belongs to the category (light) and does not require special skills in repairing electromechanical products and disassembling the autocompressor. In the event of a fuse blowing, you only need to replace it with a new one of the appropriate rating.

The second of the more common breakdowns of autocompressors, this is a chafing or breakage of the compressor supply wire. If, after checking and replacing the fuse, the breakdown has not been eliminated, it is worth visually assessing the condition of the supply wire for a break, but if the wire looks intact, then it is worth ringing it with an appropriate tester.

If the device confirms a break, it is worth either replacing the power cable or finding the break, bite off with wire cutters just above this place, strip the wires and solder to the wires remaining at the autocompressor. If the repair of the autocompressor cable did not help, then the winding of the electric motor or the vibrating coil most likely burned out, depending on the modification of the autocompressor, in this case, repairing the autocompressor is useless.

Hi car enthusiasts, pick-ups, if you have a dead car compressor, do not rush to throw it away, I will now tell you how to reanimate it in 5 minutes.

I bought a compressor a month ago and it died after 10 times of use, the motor works, but the wheel does not inflate. Well, I decided to take it apart to see why.

after opening it became clear that he was dry at all! those. no one lubricated it with anything at the factory. Completely disassembled this cylinder

this skirt on the Porsche needs to be very carefully bent around the circumference with a screwdriver or a knife (expand it)

washed with carburetor cleaner and wiped with a cloth

generously lubricated the cylinder, piston. gears and assembled back

check by turning it on and closing the nipple with your finger, creating pressure.

Voila))) shakes like that))) if you hold it with both hands, it will generally be in the red zone (with one finger there is not enough strength to hold the air)

I hope someone useful information and save a couple of thousand rubles)))

Chinese production is always alarming, consider this particular case with the Tornado autocompressor. At first glance, everything is fine. The most popular AC 580 model has a convenient handle, a bag for carrying and storing, a set of fittings for inflating various inflatable products, a maximum pressure of 7 kgf / cm², and, according to numerous reviews, reaching 1 atm. takes a little over a minute.

But is the Tornado car compressor really that good?

The accumulated already rich experience with this brand made it possible to identify a number of shortcomings.

Of course, the unit is not characterized by one minus. There are also many advantages.

• Democratic price - where as, but on average a little higher than 800 rubles.
• Quite extensive coverage of wheel radii: R12-R17.
• The soft rubber of the shock absorbers perfectly dampens the vibration of the Tornado autocompressor.
• The models use powerful engines.
• A performance of 35 l / min is quite sufficient for most city cars.

In general, if the Tornado automobile compressors created by the American genius would come to us from the homeland of this very genius, there would be no problems. Alas, the Celestial Empire is making its own contribution to the decline in product quality, and domestic craftsmen are increasing this decline.

dismantled the Chinese car pump Tornado AC-580, review, review of the tornado compressor.

The automobile compressor is a device that greatly simplifies the process of tire inflation, which was traditionally performed using a hand or foot pump. This unit can operate in automatic mode, has a compact size, and inflation of tires with its help does not require the use of physical effort. Although the autocompressor does not have a complex design, some of its components may fail over time. In order to repair the device yourself, you need to have an idea of ​​how it works and on what principle it works.

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

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

The membrane autocompressor consists of the following elements:

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

• 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 (KShM).

Autocompressor 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 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 exhaust 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 at the outlet of the apparatus does not have any impurities. In addition, in membrane units, air leakage through seals or piston rings is excluded, which has a positive effect on the performance of the autocompressor.

In piston type tire inflation machines the main part is the piston.

This type of automobile pump consists of the following components and parts:

• an electric motor that drives the drive of the device;
• compression chambers (cylinder) with intake and exhaust valves;
• air filter;
• a piston having a sealing ring;
• KShM, consisting of a connecting rod and a crank;
• crankcase, which houses the crankshaft;
• pressure gauge, which is designed to monitor the level of tire pressure and can be mounted on a cylinder or hose.

The device works as follows. The KShM is driven by either a gear transmission or a direct drive. It converts the rotational motion of the drive shaft into reciprocating motion, which causes the piston to move up and down. The piston, moving down, 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 the air exits the apparatus. Further, when the piston moves down, the exhaust valve closes, and the intake valve opens, and the cycle repeats.

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

The most common malfunctions of piston autocompressors that you can fix with your own hands include the following:

• the device does not turn on;
• the engine of the unit works, but the air does not pump;
• the device does not create the necessary pressure;
• the compressor turns off by itself.

Tire inflation compressors 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 out” by a tester. Also, if the compressor is connected to the cigarette lighter, then you need check the integrity of the fuseinstalled in the plug. If a fuse is blown, it must be replaced.

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 autocompressor, since the repair of the car compressor engine will cost 80% of the cost of a new device.

If, when the device is turned on, the sound of a running engine is heard, but air does not come out of the hose, then in order to diagnose the unit, you have to parse it:

• unscrew the 4 screws holding the crankcase cover;

• also unscrew the 4 screws mounted on the piston 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 disk with the valve from the piston head.

Under the valve is a small sealing ringwhich may wear out over time. When it is worn, the valve does not fit snugly and lets air through. As a result, the compression of the latter does not occur. Also, sometimes this ring can be displaced from its seat. If this happens, the valve will also fail 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 fixed to the motor shaft.

If the screw is loosened, then the motor shaft will rotate, and the crankshaft will remain stationary.

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

Sometimes insufficient air pressure at the inlet from the unit may be due to O-ring deformationdressed on the piston.

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

Piston sealing ring may be deformed due to overheating of the unit. To align the ring, it must first be softened. Either thinner 646 or WD-40 can be used for this purpose. 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 in the sleeve moves correctly by turning the engine shaft.

Some models of autocompressors have overheating protection. For this reason, the device may turn off spontaneously, for example, during prolonged operation. But overheating of the unit can also be caused due to factory 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 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 an ordinary beer can. Aluminum should be wrapped around the sleeve, and tightly inserted into the shirt. After these actions, heat transfer will improve, and the compressor will stop spontaneously turning off.

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 the tire inflation apparatus that can fail is membrane. Most often, it is made of rubber or other plastic material, which coarsens and becomes inelastic at low temperatures. If such an autocompressor is turned on at a low ambient temperature, the membrane will simply break. In this case, the repair of an automobile compressor of this type will consist in replacing the membrane.

Replacing the pressure gauge on the car compressor will be required if it fails. This gauge can be installed separately from the machine, 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.

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