The steering gear of Baotou Beiben Heavy Truck parts is relatively heavy. Generally, check the following parts:

1. Steering gear fault

Through inspection, if it is found that the steering gear power oil pressure is low, it indicates that the reason for the heavy direction of Baotou Beiben Heavy Truck parts is the steering gear. At this time, professional manufacturers should be invited to repair. Generally speaking, most of the steering gear faults are caused by the piston, cylinder barrel pulling, or the piston upper sealing ring damage, which causes the two piston cavities to be connected, so that the boost pressure cannot be effectively established. In addition, various sealing rings on the piston circumference and the sealing rings on the steering screw are damaged, which will also cause high pressure unloading and lower the boost pressure.

2. Booster pump fault

According to the test, when the pump pressure of Baotou Beiben Heavy Duty Truck accessory booster pump fails to reach the standard value, it is obvious that the heavy direction is related to this. First, check whether the mating surface of the flow control valve and the valve seat and the steel ball of the safety valve are not tightly sealed. If the flow valve or safety valve leaks, it can be repaired by grinding. Secondly, check whether the spring of the safety valve is invalid. This can be checked by adding a gasket behind the spring. If the maximum pump pressure increases significantly after adding a gasket behind the spring, it indicates that the spring is invalid. If there are no problems in these two parts, disassemble the booster pump. Observe whether the cavity wall of the vane pump is worn and strained. Because the cavity wall is strained, the high and low pressure cavities will be connected, and the pressure cannot be established. Generally, the cause of strain is oil dirt. If the direction is suddenly heavy, check whether the pump shaft is broken.

3. The return oil filter in the oil storage tank is blocked. The return oil filter in the oil storage tank is not maintained or replaced for a long time. It causes blockage, impedes the circulation of power oil, increases the return oil back pressure, and also makes the direction heavy.

4. Lack of oil and air in the system

If the power system is short of oil, it will cause air in the system. At this time, not only the steering is heavy, but also there is noise when steering. At this time, exhaust according to the refueling and bleeding procedures.

5. The sealing rings of the two limit valves fail. The two chambers of the piston are connected to each other, resulting in the failure of the booster.
