How to tell how much it costs to break the booster pump

1. Diaphragm pump start-stop load operation: the diaphragm pump is driven by a frequency conversion motor, if the start-stop load is too large or too small, in order to avoid the above situations as much as possible, the hard regulations on the start-up and stop load are controlled at about 30%, and the increase and decrease of the load must be completed in a period of time in the instrument, which effectively achieves the maintenance of the inverter from the process. 2. Operation of air and lubricating oil pressure system of diaphragm pump instrument

The instrument air and lubricating oil pressure of the diaphragm pump are interlocked with the main motor, the oil injection and oil discharge valves of the propellant are air-closed valves, and a certain air pressure must always be maintained, and the small action pressure of the two valves is not lower, so the instrument air pressure is generally maintained above 015MPa, and the instrument air is not stopped even after the pump is stopped, so as not to cause insufficient or excessive liquid in the propulsion fluid cavity, and the air supplied to the valve is through...

If the car booster pump is broken, the owner should pay attention to it and go to the 4S shop or repair shop to find professional personnel to replace it in time. There are cheap and expensive car power steering pumps, the cheap ones are around 300 to 400, and the expensive ones are thousands.

1.When you hit the direction or increase the oil, is there a sound, if there is a sound, listen carefully to see if it is from the booster pump, there will be a sound without the oil-booster pump.

2.Look at the booster pump for oil leakage, and replace it with a booster pump repair kit if there is an oil leak.

3.When the oil is enough, check the booster pump, and then the direction is very heavy when hitting the direction in the case of idling.

4.Slowly refuel to 15 to 2,000 rpm, you refuel while playing the direction, feel whether the direction has become lighter with your refueling, if it becomes lighter, it means that the booster pump has a problem to be replaced.

The following conditions indicate that the booster pump needs to be replaced. 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 turning.

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.

When the power steering pump is broken, the main manifestation is the steering sink.

There will also be the following manifestations:

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 turning.

The booster pump will sound if it is broken, the general cool car will sound badly, and it will not leak oil if it is broken, see if the oil in the oil cup is circulating, if it is not circulating, the booster pump is broken, and the belt can not be very loose or very tight.

Generally, there are very few broken ones, and if the oil leaks, replace them.

The phenomenon that the directional booster pump is broken:

1. When the brake is pressed, you will feel that the brake is obviously stiff, and every time you step on the pedal, the stroke is very small, and there is a feeling of pushing the foot back;

2. The vacuum pump of poor quality will make obvious abnormal noise, sometimes it is a clicking sound, and sometimes it is a popping sound;

3. After pressing the brake pedal, the pedal is neither raised nor assisted, and the phenomenon of not returning to the position appears.

Common causes of steering power pump potato digging round failure:

1. If the oil seal is aging, the oil pipe, the number of screws and the thread is loose, etc., it is okay to replace the new one according to the damaged parts;

2. Observe the oil level regularly, and if it is lower than the specified value, it is necessary to replenish the booster axial oil in time, otherwise the steering wheel will become heavier;

3. If there is oil leakage from the engine block, oil tank, transmission oil tank and cooling oil pipe, you need to go to the 4S shop or maintenance shop to find professional personnel for maintenance.

The first thing to look at is whether the booster pump is leaking oil. If the steering oil is not replaced for a long time, the probability of damage to the booster pump is very high. If it is a mechanical hydraulic steering power system, it is recommended to press the accelerator to steer when parking in place.

If the steering wheel is significantly lighter, there is a problem with the power pump.

The power steering systems on the market today can be broadly divided into three categories: mechanical-hydraulic power steering, electro-hydraulic power steering, and electric power steering. Mechanical hydraulic power steering system is usually composed of hydraulic pump, oil pipe, pressure and flow control valve body, V-shaped transmission belt, oil storage tank and other components.

This system works regardless of whether the car is turning or not, and when the speed of big turns is low, the hydraulic pump needs to output more power to get more power. As a result, resources are wasted to a corresponding extent.

Memories: Driving such a car, especially when turning at low speeds, feels that the direction is heavier and the engine is more laborious. Moreover, the pressure of the hydraulic pump is high, which can easily damage the booster system.

In addition, the mechanical hydraulic power steering system consists of a hydraulic pump, a pipeline, and a cylinder. In order to maintain the pressure, the system always works regardless of whether steering assistance is required or not, and the energy consumption is high, which is also one of the reasons for the consumption of resources. Typically, more economical cars use mechanical-hydraulic powertrains.

Summary. Secondly, the driver becomes significantly heavier when turning the direction, or there is a deviation in the direction of the rotation. If the above phenomenon occurs, it can be judged that the booster pump is broken.

The driver is noisy when he hits the direction and increases the throttle, and the steering wheel is stuck. You should get out of the car to see if the noise is coming from the booster pump.

Secondly, the driver becomes significantly heavier when turning the direction, or there is a deviation in the direction of the rotation. If the above phenomenon occurs, it can be judged that the booster pump is broken.

When the booster pump is found to be broken, it needs to be replaced immediately. Because there will be directional errors in the steering wheel during driving.
