First, the steering gear is out of order
By checking if found to be low power steering oil pressure exergy reasons in Baotou beiben heavy truck steering machine accessories. At this point should ask professional manufacturers to repair. Generally speaking, the steering gear faults are mostly due to the piston, cylinder, piston ring or strain on the damage caused by the piston two cavity exergy boost pressure can not effectively establish the. In addition to a variety of exergy on the circumferential surface of the piston ring, the sealing ring on the steering screw breakage exergy will cause pressure unloading and boost pressure drop at the end of the exergy.
2, the power pump failure
Through the test of the booster pump is not up to the standard value orientation obviously with this heavy exergy. First of all, should check the flow control valve and valve seat meshing surface, safety valve, steel ball is closed. If the flow valve or valve leakage can be repaired by grinding method of exergy. Second, check whether the spring of the safety valve is invalid. This can be through the spring back method and check if the gasket exergy in the spring behind the increase in a gasket exergy maximum pump pressure increase exergy that spring failure. If the two parts are no problem should disassemble the exergy Baotou beiben heavy truck parts cavity wall booster pump vane pump exergy observation whether the wear and tear. Because the cavity wall injury will make the high and low pressure cavity exergy thereby causing pressure build up. The reason for the general strain is oil contamination. If the direction is suddenly heavy exergy should check whether the pump shaft fracture is caused by.
3 、 the oil filter in the oil storage tank is blocked
Baotou beiben heavy truck parts tank return oil filter and long-term maintenance, replacement of exergy blockage caused by poor circulation to help the oil exergy exergy caused by back pressure increasing exergy will also make the direction of heavy.
4, the power system is missing oil
If the power system is short of oil and creates air in the system, it is not only heavy but also noisy when turning. At this point, press the gas and bleed procedures to exhaust.
5, two limit valve sealing ring failure
Causes the piston two cavities to be interlinked, creates the power failure.
