How to maintain the steering booster pump
Steering booster pump as the power source of automobile steering is the "heart" of the steering system. In developed countries, the size of the car's power steering loading rate has been close to 100%, at present, many domestic models have begun to use power steering. Therefore, in the process of popularization and use of the steering pump, we must understand and grasp its performance, principles, in order to achieve the correct use and maintenance.
First, the principle of work
The steering pump mainly has the vane, the gear type, the plunger type and so on several kinds of. From the current domestic development point of view, to promote the use of the most for the vane pump. The main parts of stator, rotor, valve plate, blade, pump body and cover etc.. Pump body with flow control valve and safety valve. When the slide valve pump when a certain opening, to achieve the required flow, excess flow back to pump the smoke cavity. If the circuit or plug an accident occurs, the system pressure exceeds the pump the maximum working pressure, open the safety valve, slide valve fully open, all the pressure of oil back to the oil absorption cavity, the system play the role of safety protection.
Two, use and maintenance of matters needing attention
1, the correct choice of the number of hydraulic oil, otherwise it will affect the efficiency and life of the pump.
2, the hydraulic oil must be clean, regular inspection, regular replacement of oil pump oil filter on the road network. The driver must be equipped with a filtering device to ensure the cleanliness of the oil. And often check, clean or replace the filter device to maintain the flow of oil.
3, if the long time does not use the steering pump, restart, not immediately full load work, at least ten minutes of no-load running time.
4, use should always check whether the pump has no leakage phenomenon, the operation is normal, there is no impact or abnormal noise, so that the timely detection and troubleshooting.
