Analyze common problems of hydraulic cylinders and their solutions

During the operation of the pressure oil cylinder, some common problems may be encountered, but there are corresponding solutions for all of them.

Oil leakage is one of the common faults of hydraulic cylinders, mainly due to the aging or damage of sealing parts. The solution is to replace the reliable seals, install them in accordance with the operating procedures, and at the same time check whether there are any faults in other components of the hydraulic system.

Another common problem is the unstable movement of the oil cylinder, which may be caused by impurities inside the oil cylinder, overly tight or loose fit between the oil cylinder and the piston rod, or bending of the piston rod, etc. The solution is to clean the impurities inside the cylinder, adjust the fit clearance between the cylinder and the piston rod, and straighten the piston rod.

In addition, the hydraulic cylinder may also experience unstable pressure or insufficient thrust. This is usually caused by insufficient fuel supply, unstable system pressure or internal leakage, etc. The solution is to check whether there is any blockage or leakage in the oil pipes and oil circuits, adjust the pressure of the hydraulic pump, and deal with the leakage problem inside the cylinder in a timely manner.

To sum up, there are corresponding solutions to the common problems of hydraulic cylinders. The key lies in regular inspection and maintenance of the equipment, promptly identifying and addressing issues to ensure its normal operation and extend its service life.
