It is likely that the middle of the cylinder is heavily worn, or the cylinder seal is damaged, and the hydraulic oil leakage occurs halfway through the travel of the cylinder rod.
You can press items after not on the pressure, open the oil cylinder cavity inspection mouth on the pressure again, see whether the oil, if the oil cylinder seal is not good cause pressure can not go up.
In particular, the above methods will have more hydraulic oil loss, inspection must pay attention to safety, people away from the inspection port.
If it is the above mentioned fault, it is recommended to replace the piston seal, if more wear must be removed cylinder repair.
The inspection ideas are as follows:
First, check the amount of oil in the oil tank to ensure that the amount of oil is sufficient.
Check whether the motor steering is consistent with the direction of the oil pump.
Check the pressure regulating valve on the reversing valve.
Four, check whether the oil road is clean, clean the oil road.
Check whether the sealing ring of oil cylinder is intact.
