Hydraulic steering units: common causes and troubleshooting
Hydraulic steering units ----common causes and troubleshooting
Steering oil leakage
Cause of failure The rubber ring at the journal is damaged or the rubber ring at the overflow valve is damaged or the valve body, the spacer, the stator and the back cover are leaking.
Remove method Clean the dirt by replacing the rubber ring or the joint surface; if it is scratched, it should be ground flat and tighten the bolts (7 bolts should be tightened every 2 times in order) To gradually tighten, the tightening torque is: 40 ~ 50 Nm).
The steering wheel turns heavy when the load is light and the load is light
1 Cause of failure The system relief valve pressure is lower than the working pressure of the steering system, or the relief valve is stuck by dirt.
2Remedy Adjust the system relief valve pressure to the specified value. If the relief valve is stuck by dirt, clean the system relief valve.
Cause of failure The fuel tank is not full, the oil suction filter is clogged or the viscosity of the oil is too high;
Remedy Refueling to the specified oil level, cleaning or replacing the filter element, use the recommended oil, etc. to eliminate;
The cause of the failure The oil pump is excessively worn, the internal leakage is too large, and the volumetric efficiency is reduced. When the system is working, the oil supply of the oil pump is less than the nominal flow of the steering gear, so that the system pressure cannot be established, and the steering is heavy;
Remove method Replace the oil pump;
The cause of the fault is that the one-way valve steel ball and the valve seat are not tightly sealed, the one-way valve steel ball falls into the valve sleeve and the valve body ring groove or the steel ball is worn, resulting in the check valve being closed when the power steering is not tight, the oil enters and exits Road connection
Remove method Replace the check valve;
The cause of the failure The steering safety valve is opened prematurely. One possibility is that the safety valve spring is broken or deformed, and the other may be that the impurity is stuck to the valve core;
Remove method Replace the safety valve or safety valve spring, and the other is to clean the impurities between the valve core and the valve sleeve.
1 Cause of failure The two-way buffer valve fails (the steel ball is stuck by dirt or the spring fails);
Remedy Clean the two-way cushion valve or replace its spring.
No human steering when steering the steering wheel
1 cause of failure The viscosity of the oil is too small;
2Remedy Use the recommended steering hydraulic oil
