Steering booster pump is broken, the performance of automotive steering booster pump is broken what phenomenon

steering booster pump as the power source of the automobile steering, steering system is the 'heart' part, in the developed countries, the size of automobile power steering loading rate is close to 100%, at present, many domestic models, has started using power steering. Turn the steering wheel steering booster pump can help drivers to reduce the use of force, and improve the safety of car driving, some drivers found playing direction is very heavy, probably because steering booster pump is broken, automotive steering booster pump is broken after will have what performance?

steering booster pump is broken will have the following performance:

the main phenomenon is to sink other such as noise sound leakage, etc.

1, steering noise increase;

2, to have the steering wheel with caton phenomenon;

3, turn the steering wheel obviously heavier;

4, when to appear to prohibit the phenomenon;

troubleshooting methods:

1, prepare new booster pump;

2, or choose to booster pump is removed, the second maintenance; Steering booster pump is broken, and its working performance, pump oil quantity is little, will cause the steering power cylinder piston moving quantity is little, or unable to move, reactions to the play to the tray and effort. And according to the specific worst, may also cause leakage of fuel oil, both of which must be solved. In addition, the cause to heavy relaxation is also linked with the strap.

by trial judge booster pump when the pump pressure can not meet the standard, clear direction and heavy. Should first check the mating surface of flow control valve and valve seat, valve ball is closed lax. If it is a flow valve or valve leakage, can repair by grinding method. If the second check valve spring failure. This can be through the spring gasket method after inspection.

why steering booster water pump bad:

in the mechanical and hydraulic power steering system, power and steering wheel Angle increment (only the size of the The angular velocity) The relevant. That is to say, only when the wheel in turn will provide power. The steering wheel to death without angular velocity, is don't need help, at this time of the hydraulic pump unloading idling. Hydraulic pump working pressure will only because the steering wheel turns too fast, rather than turning Angle is too large. In order to prevent damage of turning resistance moment is too large pump at the same time, each must be installed in the hydraulic system to limit the highest pressure relief valve. So mechanical hydraulic power steering system won't because killing damage of the steering wheel steering system resulted from the damage to the hydraulic pump.

in the electronic hydraulic steering system, hydraulic pump oil from the steering wheel Angle variation ( The angular velocity) And the speed of decision. Turn the steering wheel angular velocity at the same time, the lower the speed, the greater the degree of the motor speed is higher, the hydraulic water pump oil. When the steering wheel, there would be no angular velocity, then don't need steering, hydraulic pump unloading idling. Hydraulic pump's maximum working pressure will appear where he was quickly turn the steering wheel, but also need not worry about the direction of a place too fast will damage the hydraulic pump, because the electronic hydraulic booster will also furnish the relief valve. So electric steering booster pump won't because killing damage of the steering wheel steering system resulted from the damage to the hydraulic pump.

auto steering booster pump is generally not easy bad, if you find that just change the steering booster pump before long, broke down again, probably because the other part, caused by the big dipper hydraulic suggest you troubleshoot the reason in detail.

the steering on the market basically has 3 kinds: mechanical hydraulic booster, hydraulic power, electronic power. Whatever the booster pump, out of the question, can cause to sink and turned to the sound, the greater the lower corner voice grew louder, appear this kind of problem must be repaired as soon as possible, otherwise the booster pump wear metal dust can damage to machine, pipeline cleaning is also very trouble, don't rule out the possibility that need to be replaced.
