How do you deflate the power steering pump when it is gas?

The way to deflect the booster pump humming is to fill up the steering tank and not start the engine. The left and right steering are dismantled separately, and the steering hose connected to the steering cylinder is disassembled from the iron pipe. Turn the steering wheel, put it left and right twice, and then connect the pipes.

It is important to note that when hitting the steering wheel, you must hit it to the end, so that the gas can be cleaned.

An automotive booster pump is a component that helps improve the performance and stability of a vehicle. It is mainly to assist the driver to adjust the direction of the car, at present, the car has a booster pump, mainly the direction of the booster pump and the brake vacuum 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. Of course, power steering also plays a certain role in the safety and economy of car driving.

Because the booster oil will change the volume of the liquid according to the outside temperature, a slight lack of steering booster oil will cause the booster pump to sound after the cold car starts in the morning, and the sound of the hot car will be reduced.

Insufficient booster oil will also lead to the buzzing of the booster pump, and the booster oil should be added if it is missing, and it should be checked at the maintenance station in time if there is no shortage. If the booster oil is not clean and there are many impurities, change the booster oil.

When the booster pump hums because the bearing is too tight, turn the low shaft of the steering wheel slightly and slowly adjust it until the booster pump no longer sounds.

1. The vehicle starts to do the normal operation of the Yu Peihuo booster pump, the fuel level of the booster tank is normal, and the direction is left and right, and the back and forth is played several times.

2. Then turn off the fire and wait for 5-10 minutes to destroy the hunger bell, and then continue to hit the direction to observe whether there is a small amount of bubbles in the booster fuel tank. If the air bubbles are reduced, the vehicle can be driven normally.

3. If bubbles continue to be generated, it means that the oil inlet pipeline is damaged, and the gasket at the oil inlet pipe or interface needs to be replaced.

The directional booster pump has air, and as long as the wheel is repeatedly hit in place, the air can be exhausted. After changing the booster oil or changing the booster pump, the air can be generated after the car is started to idle in situ for 5 10 minutes, and after the oil becomes hot, the direction or run in situ, and drive normally for a period of time, after 10 20 times to hit the direction, or after 10 15 minutes of driving, the air will automatically cover the mountain and drain clean, or there is an air situation only Li, check the pipeline street, the booster pump itself and the oil storage pot. The booster oil needs to be replaced every 100,000 kilometers or every 6 years to avoid deterioration of the booster oil, affecting the service life of the booster pump and steering gear, or abnormal noise.

Hello, dear, car master exclusive technician for you service, attentive, careful, concentrate on answering your car questions, for you to find the corresponding problem solutions and solutions, will provide you with a satisfactory answer! We hope you find this service helpful. If it helps you, we look forward to your likes and attention.

Happy New Year's Day to you

Dear, hello, the pressure of the car direction booster pump, there is no way to adjust this, this is automatically adjusted.

First, the pressure of the vehicle directional booster pump is automatically adjusted according to the speed of the vehicle's engine and the speed of travel.

Second, if the steering power assist feels particularly heavy, this one should replace the steering power oil first.

Third, check whether there is a problem with the hem of the vehicle's chassis, the ball head of the arm or the rubber plane bearing on the top of the shock absorber? If there is a problem, it will also cause the direction to sink.

After refueling to the marked position, make the engine idle and turn the steering wheel back and forth to the end, and when hitting the bottom, hold it with a force of 10kg for 2 3s, and then refuel to the mark until there are no more air bubbles in the oil pump tank. If this method does not work at this time, it is recommended to go to the store to discharge the steering oil pipe screws, which is relatively more effective in eliminating them.

First of all, fill up the steering tank, do not start the engine, disassemble the steering hose connected to the steering cylinder and the iron pipe respectively; Turn the steering wheel (keep hitting to the left when you put the left steering, you can't hit in the opposite direction, and turn right to the opposite side); It is generally enough to put it twice in a row; Just connect the tubing.

Booster pump: Booster pump is mainly divided into steering booster pump and brake booster pump, among which, the steering booster pump is the "heart" of the steering system as the power source of automobile steering. The brake booster pump is a vacuum chamber with a large diameter, and there is a diaphragm (or piston) equipped with a push rod in the middle, which divides the chamber into two parts, one part is connected to the atmosphere, and the other part is connected to the engine intake pipe through a pipe.

The brake vacuum booster pump does not need to exhaust air; When replacing the brake master cylinder, the air will be exhausted, and the brake master cylinder should be installed to see whether the booster pump push rod is too long and the brake master cylinder will not be exhausted. The brake cylinder can also exhaust air, but it is not ideal. It is best to row at the interface between the master cylinder and the output oil pipe, two people operate, fill up the oil, unscrew the two oil pipes, press and hold the oil pipe interface of the master cylinder with your fingers, and the other continuously press the brake pedal until there is no air to press the brake pedal, and the other to install the oil pipe.

If not, it is necessary to exhaust the air of the four wheels and sub-pumps.

Inject the new booster oil and turn the steering wheel back and forth to let the new oil penetrate, which also serves as a wash. In order to penetrate thoroughly, it is best for the owner to turn the direction left and right sharply, and then slightly turn the direction left and right. However, experts remind that the purpose of hitting the steering wheel back and forth is to drain the old oil in the steering machine, but do not hit the steering wheel for a long time, otherwise it will cause excessive oil pressure and the steering oil will be sprayed.

According to the phenomenon of vehicle booster pump, it is the phenomenon that the internal air is not clean, according to the structure of the hydraulic steering system, after the general replacement of the booster oil, the air exclusion method is: after refueling to the mark, the engine is idling, turning the steering wheel back and forth to the end, when hitting the bottom, keep it for 2 3s with a force of 10kg, and then refuel to the mark, until there is no longer an air bubble in the oil pump tank.

In the past, most cars generally used hydraulic power steering system, so how to correctly use and maintain the hydraulic power steering pump in daily use?

Generally speaking, in normal use and maintenance, for hydraulic power steering pumps, the aspects that need to be paid attention to include the following:

1.Pay attention to choosing the correct type of booster oil when using the hydraulic power steering pump, otherwise it will affect the working efficiency and service life of the power steering pump.

2.Always check the use of booster oil, and the booster oil used must be kept clean. Replace the booster oil regularly, and the owner must have a filter device when filling the booster oil by himself.

3.If the car stops for a long time, when restarting, do not work at full load immediately, at least 10 minutes of no-load operation, and wait for the booster oil and other oils to reach normal working condition before driving.

4.When manipulating the steering of the car, pay attention to whether the power steering system is running normally, whether there is impact or noise, and whether there is leakage in the power assist oil circuit, so as to find and eliminate the fault in time.

Hit the venting screws and hit the direction back and forth. Until only the oil is out and the gas is not out.

Hit the steering wheel to the left and then to the right, and repeat a few times!

1.The directional power pump removes the steering cylinder.

The connected steering hose is ready for exhaust. Pay attention to the booster pump when installing the brake cylinder.

Whether the pushrod is too long while the top of the brake cylinder, the top does not expel air. The brake cylinder can also be vented, but not ideal.

2.The electro-hydraulic power steering system overcomes the shortcomings of the traditional hydraulic power steering system. The hydraulic pump is no longer directly belted by the engine.

Drive, but an electric pump, all working states are calculated by the electronic control unit according to the vehicle speed and other signals of the optimal state.

3.When the steering is at low speed, the electronic control unit drives the electronic hydraulic pump to output high power at high speed, so that the driver can play the rudder and save effort; When the car is running at high speeds, the hydraulic control unit drives the electro-hydraulic pump to run at a lower speed, thus saving some of the engine power without affecting the demand for high-speed steering.

Open the lid of the booster oil can. Then start the car and turn it around.

Summary. Hello dear! We are glad to answer for you, the directional booster pump has air, as long as the wheel is repeated in place, the air can be exhausted.

After changing the booster oil or changing the booster pump, the air can be generated after the car can be started to idle in situ for 5 10 minutes, and after the oil becomes hot, the direction or run on the spot, and drive normally for a period of time, after 10 20 times to hit the direction, or after 10 15 minutes of driving, the air will be automatically discharged. If there is still air after this operation, then it means that there is a problem with your current steering power pump, on the one hand, you need to consider that the type of steering power oil you replaced is not right, or the quality is too poor, and on the other hand, you need to consider that the power steering pump itself is damaged, resulting in air generation inside. Kiss!

How to discharge air from the <> direction booster pump?

How to exhaust air from large trucks.

Hello dear! We are glad to answer for you, the directional booster pump has air, as long as the wheel is repeated in place, the air can be exhausted. After changing the booster oil or changing the booster pump, the air can be generated after the car can be started to idle in situ for 5 10 minutes, and after the oil becomes hot, the direction or run on the spot, and drive normally for a period of time, after 10 20 times to hit the direction, or after 10 15 minutes of driving, the air will be automatically discharged.

On the one hand, you need to consider that the type of steering power oil you replaced is wrong, or the quality is too poor, and on the other hand, you need to consider that the power steering pump itself is damaged or bad, resulting in air generation inside.

There will be no air when there is no oil leakage or no replacement of the power booster pump, steering machine, oil pipe, etc. If you replace the oil pipe, steering machine, and booster pump, you need to exhaust the air.

If it does not turn, the system will not work and will be in a standby state waiting to be called. Due to the working characteristics of electric power steering, I feel that driving such a car, the sense of direction is better, and it is more stable at high speeds, that is, the direction does not drift as the saying goes.

After filling up the booster oil, kill the steering wheel left and right on the spot! Repeat the action! Listen to the sound of the booster pump and empty it without sizzle.

Remove the air inside the steering machine:

1. If there is a lack of oil and air in the steering power system, not only the steering is heavy, but also accompanied by "squeak" noise when steering;

2. If the steering gear is found to be leaking through the test, so that the booster oil pressure cannot be established, the seal on the rack piston should be dismantled and replaced.

When the engine is turned off, fill up the fuel tank, remove the connecting hose between the left and right steering cylinders and the iron pipe, and keep hitting the left direction when putting the left steering, and always hitting the right direction when putting the right steering, (note that you can't play in the opposite direction). Usually, it can be put twice in a row, and then the oil pipe is connected.

During the process, pay attention to check whether you need to refill the oil.

Directional power pump dismantles steeringCylindersThe connected steering hose is ready for exhaust. 。When installing the brake master cylinder, it is necessary to pay attention to whether the push rod of the booster pump is too long and the brake master cylinder is dead, and the air will not be exhausted if the stove collapses. The brake cylinder can also exhaust air, but it is not ideal.

The electro-hydraulic steering power assist system overcomes the shortcomings of traditional hydraulic steering power assist systems. The hydraulic pump used.

No more by engine belts.

Directly driven, but with an electric pump, all working conditions are calculated by the electronic control unit based on signals such as the vehicle's driving speed.

In the case of low-speed and large steering, the electronic control unit drives the electronic hydraulic pump to output more power at high speed, so that the driver can save effort in the direction; When the car is driving at high speed, the hydraulic control unit drives the electro-hydraulic pump to run at a lower speed, which does not affect the need for high-speed steering and saves a part of the engine power.

The effective methods are as follows:

1. The vehicle ** booster pump is running normally, the fuel level of the booster tank is normal, the left and right directions, and the group is playing back and forth several times.

2. Then turn off the fire and wait for 5-10 minutes, then continue to hit the direction to observe whether there are a small number of bubbles in the booster fuel tank. If the air bubbles are reduced, the vehicle can be driven normally.

3. If the code continues to produce bubbles, it means that the oil inlet pipeline is damaged, and the gasket at the oil inlet pipe or interface needs to be replaced.
