Hydraulic Power Steering Pump with Best Price

Working principle of hydraulic power steering
When driving in a straight line
The steering control valve communicates the working fluid pumped from the Steering Pump with the oil tank. The steering pump is in a unloaded state, and the power steering gear does not assist.
Turn Right:
Turn the steering wheel to the right, and the steering control valve connects the working fluid pumped from the steering pump to the R chamber, and connects the L chamber to the oil tank. Under the action of oil pressure, the piston moves downward, deflecting the left and right wheels to the right through the transmission structure, thereby achieving a right turn.
Turn left:
When turning left, the situation is reversed

MAINTENANCE TIPS

1. Working temperature: steering pump can work at -40 ～ 120 ℃, but working at high temperature for a long time will reduce the service life of the Steering System. It is recommended to take cooling measures at the outlet pipeline of the steering pump. Generally, the outlet pipeline of steering pump for passenger car will passby the front of engine to achieve the purpose of cooling.

2. System cleanliness: steering gear and steering pump are precision hydraulic components. The cleanliness of the system and fluid directly affects the service life of the steering system. It takes a large proportion for the failure of stuck valves, abnormal wear of internal components due to poor cleanliness at the early stage.

3. Duration of steering to lock: less than 10s. In emergent case, correct operation should be: return the steering wheel and steer to lock again.

4. Fluid: It is recommended to use ATF-3 automatic transmission fluid or 8# hydraulic transmission fluid. The fluid in the steering system must be replaced after the 10,000-20,000 km run-in period for new vehicle, and it is recommended to replace it every 50,000 km to ensure the cleanliness of the fluid.
