ZYB Vane type automotive steering oil pumpDetailed product description：

Product Features

ZYB blade type automotive steering oil pump is the power source of the automotive power steering system. When the engine speed of a car changes, the output flow of the steering oil pump can be maintained at a stable value, which has the characteristics of a wide range of operating speeds, stable pressure with small pulsation, low noise, and small size.  
The ZYB blade type automotive steering oil pump has passed reliability tests and evaluations conducted by Changchun and Chongqing Automotive Research Institute, as well as the Technical Center of China National Heavy Duty Truck Group. Through road tests of 30000 kilometers for buses, 50000 kilometers for trucks, and 80000 kilometers for Beijing Jeep.

Working principle
The steering oil pump, driven by the engine, supplies oil to the power steering system. As the engine speed changes, the flow rate through the throttle hole changes, resulting in a change in the pressure difference between the two ends of the throttle hole. This causes the force on the steady flow valve to change with the speed. When the speed of the steering oil pump exceeds a certain value (usually around 000 revolutions per minute), as the speed increases, the opening of the stabilizing valve gradually increases, and the overflow increases, so that the output of the steering oil pump has a relatively stable flow rate, which can maintain good stability of the steering wheel.  
When the external load exceeds the maximum pressure of the steering oil pump, the safety valve opens to unload, which can prevent system overload and protect the hydraulic steering system.
