Power steering pump
1. Working principle
There are several types of steering pumps, such as vane, gear and
plunger. From the current domestic development point of view, the
most widely used is the vane pump. The main parts are stator,
rotor, oil distribution plate, blade, pump body and back cover. The
pump body is equipped with flow control valve and safety valve.
When the pump works, the slide valve has a certain degree of
opening, so that the flow rate reaches the specified requirements,
and the excess flow rate returns to the smoking chamber of the
pump. If the oil circuit is blocked or an accident occurs, so that
the system pressure exceeds the maximum working pressure of the
pump, the safety valve is opened, the slide valve is fully opened,
and all the pressure oil is returned to the oil suction chamber,
which plays a safety role in protecting the system.
2. Precautions for use and maintenance
1. Correctly select the grade of hydraulic oil used, otherwise it
will affect the efficiency and life of the pump.
2. The hydraulic oil used must be cleaned, checked regularly, and
the oil filter on the oil suction path of the oil pump should be
replaced regularly. The driver must be equipped with a filter
device when refueling to ensure the cleanliness of the oil. And
often check, clean or replace the filter device to keep the oil
passage open.
3. If the steering pump is not used for a long time, it should not
work at full load immediately when restarted, and there should be
at least ten minutes of no-load running time.
4. When using, you should always check the steering pump for
leakage, whether it is running normally, and whether there is
impact or abnormal noise, so as to find and eliminate the fault in
time.
