What are the faults of hydraulic steering system?

[LeLuna]

Common faults of hydraulic steering system include heavy steering; steering wheel deviation; steering wheel self-rotation, unable to return to neutral position; severe steering wheel shaking; no dead point in steering wheel rotation, etc. The specific common faults of hydraulic steering system are as follows: 1. Insufficient oil suction: lack of oil in the tank or insufficient oil in the tank, resulting in the oil pump being unable to suck oil. 2. Oil pump failure: excessive wear of the oil pump, excessive internal leakage, reduced volumetric efficiency, when the system is working, the oil supply of the oil pump is less than the nominal flow of the steering gear, making the system pressure unable to be established. 3. The manual steering check valve is not installed: debris pads the check valve steel ball, making the steel ball and the valve seat not tightly sealed; the check valve steel ball falls between the valve sleeve and the valve body ring groove, resulting in the check valve not being tightly closed during power steering, and the oil inlet and outlet L4 are connected.
