Steering booster pump, as the power source of automobile steering, is the "heart" part of steering system. It is a set of gear mechanism that completes the motion from rotation to linear motion (or approximately linear motion) and is also the deceleration gear in the steering system. Steering pump mainly has blade, gear type, plunger blade, gear type, type and so on. From the current domestic development point of view, the most widely used vane pump. The main parts are stator, rotor, stator, rotor, oil distribution plate, blade, oil distribution plate, blade, pump body and back cover, etc. The pump body is equipped with a flow control valve and a safety valve. When the pump works, the slide valve has a certain opening, so that the flow reaches the specified requirements, and the excess flow returns to the smoking chamber of the pump. If the oil blockage or accident occurs, so that the system pressure exceeds the maximum working pressure of the pump, the safety valve is opened, the slide valve is all opened, all the pressure oil is back to the oil suction chamber, and the system plays a role of safety protection.
