Symptoms of defect of the Perennzo Pustosterzo pump of the PSL VROM

What is a power steering pump?

The most complex element of power steering is its pump.

Currently, a car that is not equipped with power steering is unimaginable. The booster can be electric (EUR), plumber (gur) or electro -hydraulic (Egur). With these, the power steering remains the most common type at the moment.

The power steering pump is mounted on the car engine and is trained by a transmission belt from the crankshaft pulleys. It has two important tasks, that is to say:

• Guarantees the circulation of fluids in the system;
• It maintains the optimal level of pressure.

If the power steering pump is defective, the car will remain adjustable, but the turn will be difficult. This is especially true at low speeds.

It is not advisable to drive with the defective power steering pump.

What is the role of the power steering pump?

The power steering pump is necessary both to maintain the desired pressure in the system and to circulate the oil. The most common pumps are those with pallets. These are characterized by high efficiency and wear resistance.

Such a power steering pump is made in a metal housing with a rotor of the palette that moves inside.

In the rotation process, the pallets capture the work fluid and send it under pressure to the distributor and then to the hydraulic cylinder. The pump is instructed by an engine tree pulley, so that performance and pressure depend on the number of engine rotations. In order to maintain optimal power pressure pressure, a special valve is used. The pressure created by the pump in the system can reach up to 100-150 bar.

Depending on the type of control, the power steering pumps are divided into adjustable and irregular, as follows:

• Adjustable power steering pumpsAnd – maintain constant pressure by changing the production part of the pump;
• Irregular power steering pumps – Their main feature is that the constant pressure is maintained by a pneumatic or hydraulic flap that works automatically and controls the oil pressure level.

The disadvantage of the pump driven by the engine is the modification of the pressure generated according to the rotation of the engine. For this reason, the force generated by low -speed power steering is insufficient and at high speed is excessive, which leads to such an effect as a «free steering wheel» (in other words, the steering «feedback» is absent).

To eliminate this disadvantage, a pressure regulator is included in the hydraulic start pump device, which maintains it at a certain value. The operation is very simple: when the pressure is overcome, the regulator, on the move, opens the bypass channel between the strengthening and evacuation channels and part of the pressure is issued.

The role and functions of the power steering pump:

• Create and change pressure in the system
• Redditizing the liquid to the coil of the distributor of the luggage rack, which when the steering wheel is rotated, distributes the mixture in the desired room of the hydraulic cylinder.
• Relieves the management

Symptoms pump pump defective power steering

The condition of the power steering pump affects the functioning of other units and solos, therefore the defect of the pump becomes a serious problem that should not, in any form, ignored.

The main symptoms and defects of the power steering pump:

IMPORTANT!

If it is suspected that the power steering pump would be defective or if it does not work correctly, urgently contact a car service. Even if you managed to identify yourself the defect, most likely you will not work to repair it alone and qualitatively. In addition, a defect in the power steering pump is a serious signal to verify the entire set of the management, since the lack of a single component affects the functionality of the entire system.

Causes mechanical or electrical defections

There are many factors that can lead to the power steering pump. However, the most common causes are as follows:

• The life of the power steering pump depends on Respecting the unit management rules. An old oil with wear products obstructs the pump and destroys the elements of the ensemble;
• Driving style. To aggressive leadership, especially in off -road vehicles, the elements of the pump are worn and blocked.
• The voltage of the transmission belt. A strap too narrow uses the bearing and bushes, in the case of the pumps with the bushes.
• Daca Turn the steering wheel into extreme position for more than 5 secondsA critical overload appears on the pump.
• The characteristics of the oil, Do not replace it in time (consult our material The best engine oil).

These causes lead to the premature failure of the power steering pump, as well as the ruin of the hydraulic amplifier.

Main defects in mechanical or electrical power steering pumps

How can you diagnose a defective power steering pump and when you should go to a car service?

Any man is used to his car and will easily make when there are problems with the power steering pump, but it is not necessarily to know how to determine his defect. Therefore, if you suspect that there is something wrong with the power of the power steering, you can also diagnose your defect, knowing that this is a broken power steering pump when:

• The return of the steering wheel produced automatically and a rear part of the hand
• It takes greater effort to rotate the steering wheel
• Being in the central position, the direction becomes more difficult, the driver must make more efforts to turn
• It is difficult to return to the one hand
• During the operation of the hydraulic amplifier, there is a non -specific noise.

In order to diagnose a power steering pump, it is necessary to know how to distinguish between these signs.

Also to know how to check the most recommended power steering pump is to contact an authorized service station. The mechanics will carry out inspections and diagnoses and will also take care of solving the problem.

The specialist’s advice. How to avoid the power of the power steering pump

In order for the pump to work in the optimal parameters and reach its predetermined life period in the technical book, you must do the following things:

• Check and change the power steering oil in time. His condition must be controlled every 15,000 km.
• Use only a high quality and adequate liquid according to tolerant
• Monitor the level of oil in the power steering tank
• In winter, don’t rotate the steering wheel for 1-5 minutes. Wait for the system to heat up
• If a exhaust occurs, do not use seals and additives, but contact an automotive service
• If you hear noise or sound sound, diagnose

It should be noted that the state and life of the self -components depend on your attitude towards the car, the regularity with which the technical inspection, the quality of the spare parts, the technical fluids and the fuels and the lubricants used is carried out.

He faces problems with wisdom and you will not worry in traffic.
