The hydraulic steering gear is a group of gear mechanism that completes the rotation movement to the linear movement, and it is also the deceleration transmission device in the steering system. It is an important component in the steering system. Today, Xiaobian makes a brief introduction to the fault judgment and elimination methods of hydraulic steering gear.
1, first check whether the oil pump drive belt is too loose, and then check the oil tank memory and whether the oil is cloudy and there is no foam, if found foam, should check the joint and the collection pipe fastening screw is loose, should replace the oil and oil seal if necessary.
2, turning the steering wheel is heavy, you can check whether the adjustment screw is improperly adjusted or the steering gear is too tight. Disassemble the hydraulic steering gear if necessary, check whether the metal seal ring is worn or broken, and whether the steering screw thrust bearing nut is loose.
3, decompose the oil pump, check whether the bypass valve is stuck, whether the safety valve is loose, whether the stator and blade are worn, and whether there is dirt in the tank.
4, one person with the hand to turn the steering wheel back and forth, the other person with the hand to grasp the rocker arm shaft, if you feel a large amount of open, that is, the mesh gap is too large, should be adjusted.
The above four points are small series for the hydraulic steering gear fault judgment and elimination method, I believe you have a certain understanding after reading, if you want to consult more information about the hydraulic steering gear, you can pay attention to the company's website.
