How to adjust the pressure of the car direction booster pump

There are two ways to adjust:

1. Lead a thin pipe from the outlet of the pump to the inlet of the pump, install a regulating valve on the pipe, and adjust the outlet pressure of the pump by adjusting the valve;

2. Add a regulating valve to the outlet of the pump and adjust the opening of the valve to adjust the outlet pressure of the pump.

The booster pump is mainly divided into the steering booster pump and the 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.

When the car just starts, the power of the engine in the idle state has not been transmitted to the various power mechanisms, and the direction booster has not played its role for the time being, so you feel struggling, and when you get on the road, the engine power is sufficient, and the power can be used naturally.

Landlord, there are two ways:

1.Add a regulating valve at the outlet of the pump to adjust the opening of the valve to adjust the outlet pressure of the pump; 2.A thin pipe is drawn from the outlet of the pump to the inlet of the pump, a regulating valve is installed on the pipe, and the outlet pressure of the pump is adjusted by adjusting the valve;

Determine the cause first. When the steering wheel sinks, whether both sides sink the same, whether there is a relationship with the engine speed, etc., through which you can roughly determine whether it is a problem with the steering pump or the steering machine. No matter what the problem is, it is not to adjust the pressure of the steering pump, if the car has been driving for a long time, the leakage in the steering pump or the leakage in the steering gear is more likely to increase.

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 driving, especially when turning 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.

A thin pipe is drawn from the outlet of the pump to the inlet of the pump, a regulating valve is installed on the pipe, and the outlet pressure of the pump is adjusted by adjusting the valve; Power steering oil, like any other type of oil in the car, needs to be replaced. In addition, there is another situation, that is, the tire pressure of the car is too low, which will also cause the steering wheel to become heavier, and in severe cases, it may even burst due to insufficient tire pressure.

Hydraulic power steering classification.

There are two kinds of mechanical hydraulic steering and electro-hydraulic steering, and the working principle is similar, both of which provide oil pressure to push the piston through a hydraulic pump (driven by the engine belt), and then generate auxiliary force to push the steering rod to assist the wheel steering.

The difference lies in the different drive methods of the hydraulic oil pumps provided. The mechanical hydraulic pump is driven directly by the engine belt, while the electronic hydraulic pump is electrically driven.

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.

Question: What should I do if the new car is heavy in the pure electric direction.

Can the question be lightened?

Ask about a new car. Can the direction of a new pure electric car be lightened?

Most of them are caused by the incorrect type of booster oil, the viscosity is too thin, or the oil is not of good quality, resulting in a decrease in oil pressure. You only need to change the oil again, and change to the correct type and qualified oil to solve the problem.

The pressure relief valve of the booster pump is inside the pump, and the position in the oil outlet pipe must be disassembled to adjust, by replacing the spring of the pressure relief valve or closing the pressure relief valve.

There is no direction of power assisting, all of which are circulating ball type, rack and tooth fan type mechanical transmission mode, which is more laborious to exert auxiliary force on the steering system, so that the tire steering is the hydraulic pump for you.

Before changing the steering machine, the steering was flexible and easy, and after changing the steering machine without changing the steering pump, it was light to the right and sunk to the left.

People ask how to adjust, and everyone on earth knows what this pump is for.

Regulate the pressure master pump! You probably shouldn't be a stress problem.

Summary. Hello, I am your exclusive technician, attentive, careful, dedicated to answering your car questions, for you to find a timely solution, will provide you with a satisfactory answer! Hope this service can help you!

The directional booster pump of the car cannot be adjusted by external force. The design of the power pump pressure factory has been designed, all hydraulic power assist can not adjust the overall power torque, such as the direction of the weight can be improved by changing the direction oil. Have a great day!

<> "How to do the daily inspection of automobile shock absorbers."

Shock absorbers are used to accelerate the attenuation of frame and body vibration to improve the ride smoothness and comfort of the car, and shock absorbers are installed inside the suspension system of most cars. The shock absorber is mainly used to suppress the impact from the road surface after the spring is absorbed. When passing over uneven roads, although the shock absorbing spring can filter the vibration of the road surface, the spring itself will also have reciprocating motion, and the shock absorber is used to suppress this spring jump.

If the shock absorber fails, the suspension system will sound when the car is passing over a slightly uneven road"Boom, boom"and the more uneven the pavement, the louder the sound. At this time, it may be that the shock absorber is damaged or the shock absorber rubber sleeve is broken. Under normal circumstances, the shock absorber will heat up when it is working, if it does not heat up, it means that the shock absorber is leaking.

On the same day, it was obvious that the shock absorber was leaking, and it must have been damaged, at least the oil seal was broken. It's time to consider replacing the shock absorbers.

The shock absorber can also be checked by yourself, usually by the following methods:

1.Make the car stop after driving 10km on the road surface with poor road conditions, touch the shock absorber shell with your hands, if it is not hot enough, it means that there is no resistance inside the shock absorber, and the shock absorber does not work. At this time, you can add appropriate lubricating oil, and then carry out the test, if the shell is hot, it is a lack of oil inside the shock absorber, and sufficient oil should be added; Otherwise, the shock absorber is out of order.

2.Press the bumper hard and then let go, if the car has 2 or 3 jumps, the shock absorber is working well.

3.When the car is driving slowly and braking urgently, if the car vibrates violently, it means that there is a problem with the shock absorber.

4.Remove the shock absorber to stand upright, and clamp the lower end connecting ring on the vice, pull and press the damping rod several times, at this time there should be stable resistance, the resistance to pull up should be greater than the resistance when pressing down, if the resistance is unstable or no resistance, it may be that the shock absorber is short of oil or the valve parts are damaged, and the parts should be repaired or replaced.
