The internal and external leakage of the cylinder is generally caused by the eccentric installation of the piston rod, the insufficient supply of lubricating oil, the wear or damage of the sealing ring and the sealing ring, the impurities in the cylinder and the scar on the piston rod. Therefore, when internal and external leakage occurs in the cylinder, the center of the piston rod should be re-adjusted to ensure the coaxiality of the piston rod and the cylinder; it is necessary to check whether the lubricator works reliably to ensure that the actuators are well lubricated; When the rings and sealing rings 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 are scars on the piston rod, they should be replaced.
Insufficient output force and unstable action of the cylinder are generally caused by the stuck piston or piston rod, 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 air supply line is blocked. When there is condensed water and impurities in the cylinder, it should be removed in time.
The poor buffering effect of the cylinder is generally caused by the wear of the buffer sealing ring or the damage of the adjusting screw. At this time, the sealing ring and adjusting screw should be replaced.
The damage to the piston rod and cylinder head of the cylinder is generally caused by the eccentric installation of the piston rod or the ineffectiveness of the buffer mechanism. In this regard, the center position of the piston rod should be adjusted; the buffer sealing ring or adjusting screw should be replaced.
