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. However, often motorists are not aware of what such a device is and what it is used for.
In order to ensure optimal cooling of engine parts that heat up during its operation, a special electric pump is used. Gazelle and other car models are equipped with such systems that, in addition to the main one, can also perform a number of other functions:
- air heating in the ventilation, air conditioning and heating system;
- cooling of gases that are formed in the recirculation system;
- oil cooling;
- cooling of the working fluid used in the operation of an automatic transmission ;
- turbocharged air cooling .
What can they be?
Depending on how the effect is provided, a different electric pump can be installed. "Gazelle" may have different models of such devices, but the most common are the following:
- Liquid . Such a system provides for the removal of heat from excessively heated engine elements using a fluid flow.
- Aerial . The same mechanics of work, but using air flow.
- Combined . Provides a combination of the previous two options.
On modern cars, the most often installed liquid electric pump. "Gazelle" with the help of such a system provides uniform and efficient cooling, and also does not make so much noise, which is also important for many motorists. That is why in the future we will consider the principle of operation of cooling systems on 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:
- coolant radiator;
- heater heat exchanger;
- radiator fan;
- oil radiator;
- thermostat;
- expansion tank;
In addition, a centrifugal pump (electric pump) is installed in the car. "Gazelle" today is equipped with the most popular version of such devices, which is widely used in other cars.
It is also worth noting the fact that the so-called cooling shirt is mandatory included in the scheme.
Device purpose
The radiator is used to cool a heated liquid with a stream of air, and in order to provide increased heat transfer, it is equipped with a special tubular device. Together with the main radiator, it is often also envisaged to install additional equipment, such as an exhaust gas recirculation radiator and an oil cooler. The latter is used in order to reduce the temperature of the oil in the lubrication system.
The heater's heat exchanger is used to heat the air that passes through it. To ensure a more efficient operation of this element, it is customary to install it directly in the place where the heated coolant exits the engine.
To compensate for the change in the volume of liquid due to temperature, it is customary to install a special expansion tank in the system , as a result of which refueling 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 such a device provide for the presence of a different drive: a belt, gear and many others. In some models of engines equipped with a turbocharger, to ensure normal cooling of the charge air and the turbocharger, it is customary to install an additional pump connected by the control unit.
The thermostat allows you to adjust the total amount of coolant that passes through the radiator, due to which the optimal temperature regime is maintained. It is customary to mount the thermostat in the pipe, installing between the cooling jacket and the radiator.
It is customary to install a thermostat on sufficiently powerful engines equipped with an electric heating system, with the help of which a two-stage regulation of the temperature of the liquid is achieved. For such control, its design provides for three different operating positions, and when the engine is fully loaded with electric heating, it is fully opened, after which the temperature of the liquid decreases to 90 ° C, and the tendency of the engine to possible detonation also decreases. In other situations, the fluid 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 operation algorithm is implemented 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.
Coolant is transported through the system through forced circulation provided by the electric pump ("Gazelle"). Repair of such equipment in the event of a malfunction should be carried out as soon as possible, since otherwise the engine may fail quickly enough due to excessive temperature rise.
The principle of operation of this device is such that the fluid moves through the “cooling jacket”, while providing cooling of the engine and, accordingly, heating of the coolant. She herself can move along or across, depending on the technology used.
Depending on the temperature, the fluid circulates in a large or small circle. After starting the engine, both the equipment itself and the coolant inside it have a low temperature. To accelerate heating, the liquid begins to move in 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 in a large circle, directly through the radiator. If necessary, the liquid can additionally be cooled also by air flow from the fan.
After complete cooling of the electric pump from the Gazelle, the VAZ-2114 again supplies liquid to the "cooling jacket", and during the operation of the engine, such a cycle is repeated many times.
Why install the pump on other cars?
The Gazelle electric pump circuit provides for its installation on many other domestic cars, which modern drivers quickly understood and adopted. With the onset of cold weather, each person begins to think about how to prepare his "iron horse" for the winter, because hardly anyone wants to freeze while moving. Of course, each domestic car also has its own stove, but its power is often not enough, and the Gazelle electric pump on the VAZ-2107 can significantly increase the efficiency of the heating system.
What gives an additional pump?
Increasing the efficiency of the heating system at idle is the main task for which the electric pump ("Gazelle") is installed. Repair of such a device is not required so often, and its effectiveness is significantly higher compared to the standard heating system for cars, so such a simple tool has become extremely widespread today.
If the stove normally blows idle with warm air, and the hot one turns on only after the start of movement, it means that the cooling system does not have enough good fluid circulation. The electric pump from the Gazelle on the VAZ-2109 and other similar vehicles provides much faster antifreeze movement, which will positively affect the temperature of the air from the stove even during parking.
It is worth noting that many people consider the installation of an additional pump another Kulibin idea, who are trying by some means to improve their cars with new methods, but in fact the use of such technology has long been practiced by such well-known companies as BMW and Mercedes Benz.
What can be installed?
Some people prefer to install devices from foreign manufacturers (for example, Bosch equipment). But many often use the Gazelle electric pump. Reviews about this device from people who use it are often quite positive, since it allows you to significantly improve the performance of the car for a small amount.
The Gazelle pump is a standard centrifugal pump. The flow of fluid by the blades during operation is discarded to the periphery from the center, which provides a vacuum at the inlet and increases the pumping force of the fluid. It is worth noting that the installed electric pump from the Gazelle to the VAZ cannot pump air because of too large gaps between the casing and the impeller.
What can they be?
"Gazelle" pumps can be very different, and their first difference lies in the year of manufacture. More modern models vibrate much less, and, in principle, connecting an electric pump ("Gazelle") from new models will save you from a lot of trouble and problems. The main problem that is most often found in such devices is their leakage, which leads to rather unpleasant consequences and the need for repairs. Fortunately, the procedure is relatively quick and cheap, since many workshops easily operate the Gazelle electric pump, the installation of which is now more and more often practiced by modern motorists.
It is worth noting that if you can choose a really high-quality device and at the same time carry out the installation procedure correctly, the probability of its breakdown will be minimized.
How is the installation done?
Now let's talk about how to connect an electric pump from the Gazelle. Immediately it is worth saying that the procedure is quite responsible, therefore, if you are not confident in your abilities, it is best to entrust it to some specialists.
Before installing an additional electric pump (“Gazelle”), try to wait a while until the antifreeze cools in the car, then pour it from the unit into some clean container (the container does not have to be clean if you fill in a new one later) .
Now unscrew the top four screws on the pump and lubricate the rubber gasket with sealant. During the assembly of the pump, instead of self-tapping screws, thin long bolts with nuts should be installed.
Many people think about where it is better to put an additional pump - in the gap of the outlet or supply pipe. In fact, there is no difference in where it will be placed, the main thing is to install it during the main stream. Although it is worth saying that most motorists who practice this option of upgrading their heating system say that it is best to install a new pump to the radiator of the stove.
Mounting is carried out by one of the following devices:
- washer tank mounting pin;
- Shumka standard mount mounted on the motor shield;
- studs near the battery.
The most common is the last option, which was considered above, where the device is located so that the horizontal pipe of the pump looks towards the block (for this, the iron clamp is unclenched first).
The electric pump is connected to any place convenient for you. Someone puts it on the recirculation button, someone sets the mirror to be heated, the SAUO block when the stove is activated, and many other elements.
Now disconnect the white / cyan and yellow / cyan wires from the recirculation valve, and then reconnect them as follows:
- white / blue connects to terminal 85 of the relay;
- yellow / blue connects to terminal 30;
- terminal 87 is combined with the wire of the electric pump;
The general installation procedure is as follows:
- A hose is disconnected from the outlet nozzle of the head of the unit, through which liquid is supplied to the heater, after which it is connected to the horizontal nozzle of the electric pump. The length of this hose is enough to carry out such an operation, so you should not worry about this.
- Connect a hose to the vertical pipe, which is connected from two S-shaped hoses 2108 (or another suitable one), they often stand in the cabin between the heater radiator and the faucet. The second end is connected to the block column to the place where the regular one was previously connected. Ultimately, all the clamps are pulled out, and the main thing is to remember to tighten the drain plug in the block.
- Antifreeze is poured to the limit value, the engine is spinning and all the equipment is viewed completely for leaks. Then the pump is turned on and a repeated elimination of possible leaks is carried out with a lift of various clamps. After about half an hour of engine operation, the antifreeze level is brought to a normal level.
Conclusion
Such a 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 warmed-up engine, the air starts to go much warmer from the stove, but at the same time it can hum and vibrate a little during operation, which creates unnecessary noise if the machine is turned off.
Such a pump consumes only 0.25 mA, due to which you can not worry about the fact that your device will quickly discharge the battery. Such modernization will be useful to many, and especially those who live in the northern regions. Instead of an additional pump, the VAZ-2110 can be equipped with a high-performance pump like the LUZAR "TURBO", 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 remodel a VAZ stove so that the air flows on the sides and legs become much more efficient, or install an additional heater. But in any case, the option of installing an additional pump is the most effective means.
Basically, the use of such modernization is relevant for those people who spend a long time in the winter in a car and suffer from a lack of hot air inside the cabin. That is why in their case, it is important to modernize the equipment with an additional pump, with which it will be possible to increase the efficiency of the air conditioner and the engine cooling system, which is also important. The main advantage of using this technology is that a person can get efficient heating even while the car is standing still and not moving, which is rarely provided for in standard cars.
