How to protect the power booster pump from wearing? How can a car booster pump be broken

At the same time, in order to prevent excessive rotational resistance torque from damaging the oil pump, a safety valve must be installed in each hydraulic system to limit the maximum pressure.

Carry out maintenance frequently, and replace bad parts in time.

Many parts of the car will have certain problems if they are not well cared for for a long time, and the protection system will wear out relatively quickly in the outermost part.

Be sure to maintain it regularly, don't wait for the parts to go wrong.

Regular maintenance, go to the 4S shop for repairs.

Buy some instruments related to steering assistance.

The car booster pump is an important component in modern automobiles, which can help the driver control the steering wheel of the car more easily. However, there are times when a car's booster pump malfunctions, making it difficult for the driver to control the directional trap disc. So, why do car booster pumps break?

First of all, automotive booster pumps can fail due to wear and tear. As the car is used for more time, parts such as seals and bearings of the booster pump will continue to wear out, which will lead to a gradual decline in the performance of the booster pump. If these worn parts are not replaced in time, they will eventually lead to the complete failure of the booster pump.

Secondly, the car booster pump may fail due to oil problems. If the car's booster pump is not full of oil or the quality of the oil is not good, this will lead to a decrease in the efficiency of the booster pump and even lead to damage to the booster pump. Therefore, it is very important to check and replace the booster pump fluid in time to protect the normal operation of the booster pump.

Finally, automotive booster pumps can also malfunction due to other issues, such as incorrect installation of the booster pump, damage to the transmission belt of the booster pump, and so on. Therefore, if you find that there is a problem with the car booster pump, you should find a professional car maintenance technician in time to check and repair it.

In short, the automotive booster pump is a very important component in the car, and if it fails, it will seriously affect the safety and driving experience of the driver. Therefore, we should regularly inspect and maintain the car booster pump to ensure the normal operation of the car.

Due to the recent extremely cold weather, many customers are constantly inquiring about steering system failures.

The question is roughly as follows:

Unassisted, Abnormal Noise, Unassisted Cold Cars, Unassisted Hot Cars, or Unassisted Hot Cars.

The direction is heavy, or the idle speed is high, the power assist effect will be good, or the high-pressure oil pipe will explode, etc.

Here's why. The oil pipe is aging, the oil pot is too dirty, and the quality of the booster oil is not good; The long-term maintenance of the booster pump leads to serious wear and tear of the pump, and the unclean oil circuit leads to the blockage of the fuel injection valve, which affects the normal operation.

1.Abnormal sound of the power steering pump (abnormal sound when idle steering).

1: There are white bubbles on the oil surface of the oil pot (mixed with air).

Cause analysis. 1) Whether there is a leakage point at the connection between the oil pot and the hose.

Whether there is a leak point at the connection between the rubber hose and the booster pump.

Whether there is a leak point in the hose itself.

Is the hose aged, elastic or loose, and can it act as a seal?

2.The oil in the oil pot is spewed outward.

Cause analysis. Whether the inlet pipe has been removed or crushed.

3: There are impurities mixed in the oil circuit.

Check the location: The filter at the bottom of the oil pot is free of impurities.

The liquid guesses whether there are impurities in the spool valve of the booster pump.

Two: resteering.

1.When steering, the oil inlet pipe of the booster pump is squeezed, and the position is checked: whether the oil inlet hose is aged, resulting in poor oil suction of the booster pump.

Solution: Replace the oil pipe.

2.The oil in the oil pot does not flow well.

Check the location: The strainer at the bottom of the oil pot is not too dirty.

Solution: Remove the strainer at the bottom of the oil pot and clean it with detergent.

3.There is a "squeak" sound in the direction, and the high-pressure oil pipe will shake when it is severe.

Check the location: whether there is air in the oil circuit.

Solution: Check the oil leakage of the oil system and replace the corresponding accessories.

4: Heat up within 4-5 minutes after the booster pump is installed.

Check the position: If the oil circuit is blocked, check the two inlet and outlet ports of the oil circuit and the steering gear, as well as the oil return pipe between the two cylinders and the rotary valve of the steering gear.

Solution: Clean the oil circuit to solve the blockage.

5: Steering left and right is heavy.

Check the parts: check the inner and outer ball tie rods, and check whether the knuckle kingpin and bushing are worn.

Assist the internal grinding of the pump.

6.One-way steering is heavy.

Check the parts: check whether the mechanical parts are worn or faulty, and check whether the steering valve and oil circuit of the steering gear are blocked.

Solution: Check for blockage.

7: Unpowered steering.

Check the location: whether the booster oil is sufficient.

Troubleshooting solution: clean the booster pump slide valve.

8: The turning gap is too large or there is abnormal noise when turning or turning.

Check the inner and outer tie rod ball joints.

If the booster pump is broken, it will have an impact on driving, the steering wheel will rotate very heavily, and there will be potential safety hazards during driving.

The problem of the booster pump will mainly cause steering heave and steering noise, the louder the corner at low speed, the louder the sound, it must be repaired as soon as possible, otherwise the metal scraps worn by the booster pump will damage the steering machine, and the pipeline cleaning is also very troublesome, and it needs to be replaced in serious cases.

Classification of automotive power assist pumps:

1. Mechanical hydraulic power steering system.

2. Electro-hydraulic power steering system.

3. Electric power steering system.

The role of the booster pump:

The steering power assist is mainly to assist the driver to adjust the direction of the car and reduce the force of hitting the steering wheel for the driver. Power steering also plays a certain role in the safety and economy of car driving. Raid the stool skin.

Extended Information: Performance of a Broken Power Steering Pump:

The most important phenomenon is the steering sinking, and others such as noise, abnormal noise, and oil leakage.

1. The noise increases when turning;

2. There is a jamming phenomenon on the steering wheel when turning;

3. The steering wheel becomes significantly heavier when steering;

4. The phenomenon of inaccurate pointing occurs when the steering is rough and clear;

Working principle of mechanical hydraulic power steering system:

The mechanical hydraulic power steering system is generally composed of hydraulic pumps, oil pipes, pressure and flow control valve bodies, V-shaped transmission belts, oil storage tanks and other components.

This system works regardless of whether the car is steering or not, and when the speed of the large steering is low, the hydraulic pump needs to output more power to obtain greater assistance.

So, it's also a waste of resources to a certain extent. When cornering at low speeds, I feel that the direction is heavier and the engine is more laborious. And because the pressure of the hydraulic pump is very high, it is also relatively easy to damage the booster system.

The mechanical hydraulic power steering system consists of a hydraulic pump and a pipeline and a cylinder, in order to maintain pressure, regardless of whether the steering power is required, the system must always be in working condition, and the energy consumption is high, which is also a reason for resource consumption.

Generally, economic cars use more mechanical hydraulic power assist systems.
