For the insulation of the car's interior electric pump. "Gazelle", electric pump: characteristics, repair, connection, reviews

Most modern cars use a specialized electric pump. "Gazelle" is equipped with one of the best such devices in terms of price and quality, so many are interested in its installation. At the same time, often motorists do not know what a device is and what it is used for.

In order to ensure the optimal cooling of the engine parts that are heated during operation, a special electric pump is used. "Gazelle" and other models of cars are equipped with such systems that, besides the main one, can also perform a number of other functions:

• Heating of air in the ventilation, air conditioning and heating system;
• Cooling of gases that form in the recirculation system;
• Cooling oil;
• Cooling of the working fluid used in the automatic transmission;
• Air cooling in turbocharging.

How can they be?

Depending on how the effect is achieved, a different electric pump can be installed. "Gazelle" may have different models of such devices, but the most common are the following:

• The liquid . Such a system provides for the removal of heat from excessively heated engine components by the flow of liquid.
• The air . The same mechanics work, but with the use of air flow.
• Combined . It provides for combining the previous two options.

On modern cars, the most often installed liquid electric pump. "Gazelle" with the help of such a system is provided with a uniform and effective cooling, and also does not so much noise, which is also important for many motorists. That is why in the future we will consider the operation of cooling systems using the example of such equipment.

Design options

The structure of the cooling system is quite similar for diesel and gasoline engines, and it includes a large number of elements, including:

• Radiator of a cooling liquid;
• Heat exchanger for the heater;
• Radiator fan;
• oil radiator;
• thermostat;
• expansion tank;

Among other things, a centrifugal pump (electric pump) is installed in the car. "Gazelle" today is equipped with the most popular version of such devices, which was widely used in other cars.

Also worth noting is the fact that the circuit necessarily includes the so-called cooling jacket.

Purpose of the device

The radiator is used to cool the heated liquid with a stream of air, and in order to provide increased heat transfer, it is equipped with a special tubular device. In addition to the main radiator, installation of additional equipment, such as an exhaust gas recirculation and oil cooler, is often envisaged. The latter is used to ensure a reduction in the temperature of the oil in the lubricating system.

The heat exchanger of the heater is used to heat the air that passes through it. To ensure more efficient operation of this element, it is customary to install it directly at the point where the heated coolant exits the engine.

In order to compensate for the change in the volume of the liquid due to temperature, it is customary to install a special expansion tank into the system , so that the filling will be carried out through it.

In order for the liquid to circulate normally in the system, an electric pump ("Gazelle") can be installed in it. The characteristics of this device include the presence of a different drive: belt, gear and many more. In some engine models equipped with a turbocharger, it is customary to install an additional pump connected by the control unit to ensure the normal cooling of the charge air and the turbocharger.

The thermostat allows you to regulate the total amount of coolant that passes through the radiator, thereby maintaining the optimum temperature regime. The thermostat is mounted in a pipe fitting between the cooling jacket and the radiator.

On sufficiently powerful engines it is customary to install a thermostat equipped with an electric heating system, by means of which it is possible to regulate the temperature of the liquid two-stage. For this control, three different operating positions are provided in its design, and when fully loaded to the engine by electric heating, it is fully opened, after which the temperature of the liquid decreases to 90 ° C, and the propensity of the engine for possible detonation decreases. In other situations, the liquid that is pumped by the electric pump ("Gazelle"), the temperature characteristics should be at 105 ° C.

How does the cooling system work? Description of the circulation path

The cooling operation is mainly provided by the engine management system. In modern drives, the algorithm works on the basis of a mathematical model that takes into account many different parameters, after which optimal activation conditions are set, as well as the operating time of the structural elements.

Cooling fluid is transported through the system through forced circulation, which is provided by an electric pump ("Gazelle"). Repair of such equipment in case of malfunctions should be carried out in the shortest possible time, otherwise the engine can quickly fail due to excessive temperature rise.

The principle of operation of this device is such that the liquid moves through the "cooling jacket" while cooling the engine and, accordingly, heating the coolant. It itself can move along or across, depending on the technology used.

Depending on the temperature, the liquid circulates in a large or small circle. After starting the engine, both the equipment itself and the coolant contained in it have a low temperature. To accelerate the warm-up, the liquid begins to move along a small circle without getting into the radiator.

During its heating, the thermostat gradually begins to open, as a result of which it moves already along a large circle, directly through the radiator. If necessary, the liquid can additionally be cooled also by the airflow from the fan.

After the complete cooling of the electric pump from the Gazelle to the VAZ-2114, it again supplies the liquid to the cooling jacket, and this cycle is repeated many times during the engine operation.

Why install the pump on other cars?

The scheme of the electric pump from "Gazelle" provides for its installation on many other domestic cars, which was quickly understood and adopted by modern drivers. With the onset of cold weather, each person begins to think about how to prepare his "iron horse" for the winter, because hardly anyone will want to freeze during the movement. Of course, every domestic car is equipped with its own stove, but its power is often not enough, and the electric pump from Gazelle to VAZ-2107 can significantly increase the efficiency of the heating system.

What does the additional pump give?

Increasing the efficiency of the heating system at idle is the main task for which an electric pump ("Gazelle") is installed. The repair of such a device is not required so often, and its efficiency is much higher compared with the standard system of heating cars, so this simple tool has become extremely widespread to date.

If the stove normally blows at idle with warm air, and hot starts only after the start of the movement, then the cooling system does not have enough good circulation of the liquid. The electric pump from "Gazelle" on VAZ-2109 and other similar cars provides much faster movement of antifreeze, which will positively affect the temperature of the air from the stove, even during parking.

It should be noted that many people consider the installation of an additional pump as another idea for the kulibins, who are trying to improve their cars with new methods by some means, but in fact the use of such technology has long been practiced by such well-known companies as BMW and Mercedes Benz.

What can I install?

Some prefer to install devices from foreign manufacturers (for example, equipment from Bosch). But many more often use an electric pump "Gazelle". Reviews about this device from people who use it, often quite positive, as it allows for a small amount to significantly improve the performance of the car.

Pump "Gazelle" is a standard centrifugal pump. The flow of liquid by the blades during work is thrown to the periphery from the center, which provides a vacuum at the inlet and increases the force of pumping the liquid. It should be noted that the installed electric pump from Gazelle to the VAZ can not pump air because of too large gaps between the hull and the impeller.

How can they be?

"Gazelle" pumps can be very different, and the first difference is in the year of release. More modern models are much less vibrant, and, in principle, connecting the electric pump ("Gazelle") from the new models will save you a lot of hassle and problems. The main problem that most often occurs in such devices is their leakage, which leads to rather unpleasant consequences and the need for repair. Fortunately, the procedure is relatively fast and cheap, as many workshops easily service an electric pump to the "Gazelle", the installation of which is increasingly practiced today by motorists.

It should be noted that if you can choose a really high-quality device and at the same time correctly carry out the installation procedure, the probability of failure will be minimized.

How is the installation carried out?

Now let's talk about how to connect the electric pump from the "Gazelle". Immediately it is worth mentioning that the procedure is quite responsible, therefore, if you are not sure of your abilities, it is best to entrust it to some specialists.

Before you install an additional electric pump ("Gazelle"), try to wait a little while the antifreeze cools down in the car, then drain it from the unit into some clean container (the container does not have to be clean if you later fill it with a new one) .

Now unscrew the upper four screws on the pump and lubricate the rubber seal with a sealant. In the process of assembling the pump, instead of screws, thin long bolts with nuts should be installed.

Many people think about where it is best to put an additional pump - in the gap of the outgoing or supply nozzle. In fact, there is no difference in where it will be put, the main thing is to install it during the main thread. Although it should be said that the majority of motorists practicing this option to modernize their heating system, say that it is best to install a new pump up to the radiator of the stove.

Mounting is performed by one of the following devices:

• A washer of a fastening of a tank of a washer;
• Fixation of staff noise, installed on the motor shield;
• Hairpins near the battery.

The most common is the last option, which was discussed above, where the device is positioned so that the horizontal branch pipe of the pump looks toward the block (the iron clamp is previously unclipped).

The electric pump is connected to any location convenient for you. Someone puts it on the recirculation button, someone sets on heating the mirrors, the SAUO unit when the stove is activated, and many other elements.

Now disconnect the white / blue and yellow / blue wires from the recirculation valve, and then reconnect them as follows:

• White / blue is connected to terminal 85 of the relay;
• Yellow / blue is connected to terminal 30;
• Terminal 87 is combined with the electric pump wire;

The general installation order is:

1. From the outlet of the head of the unit the hose is cut off, through which the liquid is supplied to the heater, after which it is connected to the horizontal branch pipe of the electric pump. The length of this hose is enough to perform such an operation, so you should not worry about it.
2. To the vertical connection, connect a hose that is connected from two S-shaped hoses 2108 (or other suitable), they often stand in the passenger compartment between the radiator of the heater and the faucet. The second end is connected to the block column to the place where the original one was previously connected. In the end, all the clamps are stretched, the main thing is not to forget to screw the drain plug in the block.
3. Fills the antifreeze to the limit value, turns the ICE and looks through all the equipment for leakage. Then the pump is turned on and repeated elimination of possible leaks with suspenders of various clamps is carried out. Approximately in half an hour of work of the engine the level of antifreeze is brought to a normal level.

Conclusion

This refinement shows itself only from the best side, which is confirmed by numerous reviews of motorists. When you turn on the pump from the "Gazelle", even on a slightly warm engine, the air starts to go from the stove much warmer, but while doing this, it can hum and vibrate a little, which creates unnecessary noise if the machine is muffled.

This pump consumes only 0.25 mA, so you do not have to worry about the fact that your device will quickly drain the battery. Such modernization will be useful for many, and especially for those who live in the northern regions. Instead of an additional pump, a higher capacity pump like LUZAR "TURBO" can be installed on the VAZ-2110, which also has many positive qualities.

There are also many other options for how you can make the work of a regular stove much more productive. For example, some people remake the VAZ stove so that air flows on the sides and legs become much more effective, or install an additional heater. But in any case, the option of installing an additional pump is the most effective tool.

In general, the use of such modernization is actual for those people who spend a long time in the winter in the car and suffer from a shortage of hot air inside the cabin. That is why, in their case, it is important to modernize the equipment with an additional pump, with the help of which it will be possible to increase the efficiency of the air conditioner and the engine cooling system, which is also very important. The most important advantage of using this technology is that a person can receive efficient heating even while the machine is stationary and does not move, which is rarely provided for in standard cars.
