Causes and solutions to noise
First of all, the function of the filter element should be understood.
Second, when the pressure of the oil return port is too high, it can eliminate the pulse, prevent bubbles and calm the oil surface.
Therefore, the pressure difference between the inside and outside sides of the filter element will be too large when the filter element is blocked by dirty hydraulic oil, so the oil surface is in an unstable state.
Under the condition of the oil level changes, due to the large medial is negative, it would be easy to make the air inlet pipe, with the bubbles with the flow of the hydraulic oil into the pump body, within the pump is extruded and aerodynamic noise generation.
At this point, only one filter element of steering auxiliary pump needs to be replaced, and the steering hydraulic system needs to be thoroughly cleaned, and the pure standard hydraulic oil can be replaced, and the failure can be completely solved.
In fact, not only will the filter block generate noise, but also the pneumatic noise once the filter core is damaged or displaced.
Troubleshooting problems of automobile power pump:
Through a comprehensive view of the car auxiliary pump, check the car auxiliary pump may appear problems
1. Check the pump body, direction machine and hydraulic pipeline for oil leakage;
2. Whether the hydraulic oil in the tank is between the upper and lower limits, and whether the belt is moderately loose;
3. Observe whether the hydraulic oil is metamorphic; if it is black, it is metamorphic;
4. Observe the clarity of the hydraulic oil and the bubbles in the flow.
Solutions to the problem of automobile power pump:
1. Repair or replace pump body, directional machine and hydraulic pipeline to prevent oil leakage.
2. Adjust the oil amount of the hydraulic oil in the tank, and adjust the conveyor belt to loosen to make it moderate.
3. If the hydraulic oil deteriorates, replace the hydraulic oil.
