Causes of cylinder failure

1. The internal and external leakage of the cylinder is generally caused by the eccentric installation of the piston rod, insufficient supply of lubricating oil, wear or damage of the seal ring and seal ring, impurities in the cylinder and scars on the piston rod. Therefore, when the cylinder leaks internally and externally, the center of the piston rod should be readjusted to ensure the coaxiality of the piston rod and the cylinder; the lubricator must be checked frequently to ensure that the actuator is well lubricated; When the ring and sealing ring are worn or damaged, they must be replaced in time; if there are impurities in the cylinder, they should be removed in time; if there is a scratch on the piston rod, they should be replaced with new ones.
2. Insufficient output force and unstable movement of the cylinder are generally caused by the piston or piston rod being stuck, poor lubrication, insufficient air supply, or condensed water and impurities in the cylinder. In this regard, the center of the piston rod should be adjusted; check whether the lubricator works reliably; whether the gas supply line is blocked. When there is condensed water and impurities in the cylinder, it should be removed in time.
3. The cushioning effect of the cylinder is poor, which is generally caused by the wear of the cushion seal ring or the damage of the adjusting screw. At this time, the sealing ring and adjusting screw should be replaced.
4. Damage to the piston rod and cylinder head of the cylinder is generally caused by the eccentric installation of the piston rod or the failure of the buffer mechanism. In this regard, the center position of the piston rod should be adjusted; the buffer seal ring or the adjusting screw should be replaced.
