Why does the hydraulic cylinder move slowly or weakly? How to troubleshoot?

2025-04-28

Slow movement may be caused by many reasons: First, check whether the system pressure has reached the set value and whether the axial piston pump output is normal. Excessive leakage in the oil cylinder is a common cause. Wear of the piston seal will cause the high and low pressure chambers to communicate with each other, and the seals need to be disassembled and replaced. Scratches on the inner wall of the cylinder will also increase leakage. Minor scratches can be repaired by honing, and severe wear requires replacement of the cylinder. Excessive external load or mechanical jamming will increase movement resistance. The guide rails, hinge points and other parts should be checked. Excessive oil viscosity or low oil temperature will increase flow resistance. The appropriate viscosity oil should be selected and preheated. Control valve core jamming or improper flow adjustment will also limit the speed of the oil cylinder. The valve function needs to be checked.
