Fuel pump Bosch: characteristics, structure, performance and reviews

The Bosch Fuel pump is a critical component of the power system of the car. With their help, it is the supply of fuel to the engine of a car. This important part serves to connect the fuel tank and engine, located at some distance from each other. In the same brands of fuel pumps was not provided, as fuel came to the engine on the gasoline hose under the action of gravity.

Varieties of fuel pumps

Nowadays, vehicle manufacturers equip their products with fuel pump mechanical or electric type. First used in automobiles carburettor type. They fuel under low pressure is at the carb. Electric fuel pumps, in contrast, organize the flow of fuel to the engine under high pressure.

Now the fuel pumps break often. As a rule, blame yourself careless drivers.

The Main causes of breakage:

• Clogged fuel filters;
• Drive with empty fuel tanks.

In the presence of these reasons for fuel pump Bosch operates at its full capacity, and therefore wears out much faster.

Drivers must fulfill the requirements:

• Provide at least a half fill of the tank;
• Monitor the serviceability of the fuel filter.

Mechanical fuel pumps provide the fuel getting from the fuel tank to the engine. They do not require high pressure, as they are located close to each other.

Electric fuel pump

Electric fuel pump Bosch uses a higher pressure than mechanical. High pressure allows you to push fuel directly into the engine. In the models of previous generations fuel pump operated continuously. In modern gasoline pumps its speed is determined only by the requirements of the device. The fuel pumps of this type controlled by an electronic system of the car. It automatically calculates the position of the throttle, the composition of the exhaust and the proportion of fuel to air mixture.

Be aware that electric fuel pumps are working loud and heated as the engine is supplied with fuel under pressure. Therefore, these pumps are fitted in the tank that makes it possible to achieve cooling of the fuel pump using the fuel. Additionally it can be noted that this arrangement of the pump makes it work almost noiselessly.

The electric pump is controlled by a signal of the motor. After installation of the ignition switch to activate the car's computer gives the signal that the fuel pump is running, and it is the charge of electricity. The engine is located inside the fuel pump some time rotates, raising the pressure in the fuel system. If the signal from the computer on the motor no more than two seconds, the fuel pump is switched off instantly, for safety reasons.

In the first seconds after the start of engine operation, the driver hears how the pump works. The fuel enters the fuel pump at a special tube, after which it enters betfilter, cleansing from contamination of the fuel mixture. With this purpose, the fuel filter needs periodic changing. This allows to achieve effective cleaning of the fuel. In the next stage, pre-cleaned fuel flows to the engine. The fuel pump runs until the engine is turned off.

Pump for Vase

The VAZ-2110 fuel pump electric Bosch used most often, because it has a universal size, constantly has to sell and is not very expensive.

Model Bosch for Vase

For each type of fuel systems manufacturer delivers a standalone unit.

Performance Bosch fuel pump for VAZ-2110 is 3-3. 8 bar.

A Significant number of owners after the failure of the regular pump change the pump from Bosch, working in regimes with high pressure. This parameter is the fuel pump can affect fuel consumption because the car is equipped with the return, through which excess fuel is returned back to the tank. Additionally provided with a regulator of pressure of fuel. Fuel costs can increase when rail fails to create optimal pressure. In the result, the injectors are already functioning correctly – they do not spray, and just pour the fuel that was not consumed.

Design

Device fuel pump Bosch is. The main part is the body that has fittings for inlet and outlet.

Inside it is an electric DC motor with a roller pump, two valves and two studs threaded for connection to power.

The parameters of the model 0580453453

Fuel pump Bosch 2110 can have various options. Different models can be of different length or diameter. To adjust the diameter of the housing by gaskets made of rubber, resistant to gasoline. In addition, the fuel pumps may have different pressure and the location of the chips onterminals. Mesh device has the same number of seats, but may have another form.

The Chip can be converted into a terminal or a variant of VAZ. The length of the fuel pump determines its functioning in conditions of small volume of fuel in the tank.

For Example, for models Bosch 0580453453 length equal to 105 mm, 0580453449 – length 6.5 cm, 0580453465 – length 9,0 cm

The Fuel pump is in the gas tank of a car, being immersed in fuel. Inside is a motor which serves to drive the pumping element. The combination of the components of the fuel pump feeds fuel under high pressure. In the end, the fuel pump makes noise and requires cooling. This problem is solved by immersing the pump in fuel tank. The fuel cools the warmed up equipment and suppressing noise.

The Right choice of fuel pump

Fuel pump for VAZ-2110, bought on the market, will cost two times cheaper than the same model purchased at the specialty shop. However, the store more likely to get a quality item.

Fuel pump Bosch high pressure is enclosed in a rugged hermetically sealed package. The package is a highly refined gasoline. If you feel gasoline smell, there is the tightness of the packing, and there is a risk of corrosion damage in the fuel pump.

Equipment located in the submerged condition, exposed to the lubrication and cooling fuel. If the fuel additives used are low quality, it can be corroded electrical mechanisms of the fuel pump. If the device is operated dry without the use of additional substances brush are erased, and it overheats.

Many car owners intend to replace fuel pump Bosch, the characteristics of which deviated from normal values due to prolonged use. The pump pressure should correspond to 7 atmospheres.

Faulty fuel pumps

Let's Talk about Troubleshooting the fuel pumps, the methods of their Troubleshooting.
the Least prone to failure component of the pump is the motor. The explanation for this is the mode of its operation, allowing to provide an intensive cooling and constant washing. Most often broken centrifugal vane hydromagnesite. Due to the presence of minute solid impurities, appearing in the gas tank along with gasoline, the friction parts of the compressor (rotor, stator, rollers) over time are subjected to considerable wear. At the same time, the seals between them are weaker. As a result of lost efficiency and decreases the operating pressure provided by the fuel pump. This problem occurs due to aging of the fuel pump. In the initial period of use, it is virtually nonexistent. To determine its possible on a special stand to check the performance and provide the pressure on the outlet fitting. If the fuel pump accumulates defects as a result of aging, the car loses throttle response and starts, interruptions in the operation of the internal combustion engine when the latter is transient. If the wear becomes significant, the pressure drop in the circuit may reach such proportions that the engine will fail to start.

Signs of damage

A faulty fuel pump is indicated by the increase of noise during its working. This speaks to the natural wear of the compressor or strong bullies him rubbing parts. The trouble often manifests itself in the winter due to the fact that gasoline gets wet, then becomes ice. The resulting ice crystals fall into the millstone fuel pump, istira and kicking parts of the compressor, forming on the surface of deep cavities. Often defects appear in the guide grooves of the rotor of the supercharger.

Included in the electric fuel pump bearings often become useless early parts of the supercharger. The main cause of problems with the normal functioning of the fuel pump – abrasion of friction parts of the compressor.

Repair of fuel pumps

In the General case, the fuel pump VAZ Bosch along with any other repair is not recommended. In the event of a malfunction they usually need to be replaced. But in real life, if you can skillfully crack the rolling of the pump housing of aluminum, subsequent actions to repair and rebuild the fuel pump is not a problem.

When the fuel pump of high pressure Bosch opened and completely disassembled, all its component parts should be carefully examined. Special attention should be paid to hydromagnesite. If it is repairable, then you can decide to repair the fuel pump.

Definitely need to replace electric motor brushes. You can take them with the same fuel pump. You also need to pierce manifold. Any damage to the armature winding of the motor need rewinding. Doing fast, you need with special attention to the preservation of channels for the fuel, available in the anchor grooves. Centrifugal blower is detachable. Grind the damaged surface of the friction parts of the compressor.

Grain grinding stone should not exceed 50 microns. Small wear on the rotary grooves is not essential to the operationengine, and the processing is not subjected. Just when will be the reverse Assembly, the rotor vane of the pump is placed in its stator by the other party. If there are large fins on the rollers, they need to change, using as donor domestic bearings. In the absence of the possibility of changing the rollers the ends of them need to grind the magnetic table in maganoy the mandrel.

There is another detail, often with severe frosts leading to breakage of the brand new fuel pump. The coupling fork. This component is considered to be irremovable. But even coupling the fork has the ability to replace. This requires turning the complex repairs to the armature of the pump motor.

The Need with utmost care and precision, a special cutter to make the groove in the body of forks made of plastic and the groove tightly to impose new ones.

The updated fork is Fixed using dental cement or by microwindow. Possible and the combination of these two methods. It is not necessary to carve a fork to replace the plastic. Better if it is aluminum or bronze.

Well done repair of the inner can go down the drain if the outer Cup electric fuel pump is securely zavalova. Usually, open and zavaliat the glass back is possible only once. And it demands the highest qualification in carrying out these operations. The opening of the Cup is preferably performed manually, e.g. by a blunt screwdriver. Because under the rolling located a strip of rubber having the form of coils with a circular cross section. We must strive to ensure that it does not hurt. Reverse rolling can be performed method of testing using a lathe. To fix the fuel pump on a lathe, and to secure the pressing of the glass to the body can, and fabricated special tooling.

The Kit

To Do a repair help repair kit, fuel pump Bosch, consisting of rubber products.

All of the above shows that one of your desires is not enough to repair the fuel pump was carried out efficiently. Still requires a high professionalism of the master and special tooling. This method of repair is realizable only equipped workshop. In addition, at larger stations there are a large number of used parts that you can use. If these conditions can be qualitatively repaired two-thirds of the total number of failed fuel pumps.

Real life proves that after restoring the fuel pumps can work for some time.

Reviews

Drivers who used fuel pump Bosch, speak of him mostly sympathetic. Among the advantages it is called low cost, reliability, durability. As noted cons noisy work.
