Cylinder failure

Due to improper cylinder assembly and long-term use, pneumatic executive components (cylinders) are prone to internal and external leakage, insufficient output force and uneven action, poor buffering effect, piston rod and cylinder head damage and other failure phenomena。

(1) The internal and external leakage of the cylinder is generally caused by eccentric piston rod installation, insufficient supply of lubricating oil, wear or damage of the sealing ring and the sealing ring, impurities in the cylinder and the piston rod are scarred。所以，When the cylinder appears internal and external leakage，The center of the piston rod should be re-adjusted，To ensure the concentricity of piston rod and cylinder;Check the reliability of the oil mist regularly，To ensure that the actuator is well lubricated;When the sealing ring and sealing ring are worn or damaged，Must be replaced in time;If there are impurities in the cylinder，Should be removed in time;When there is a scar on the piston rod，Should be renewed。

(2) The insufficient output force and unstable action of the cylinder are generally caused by the piston or piston rod being stuck, poor lubrication, insufficient air supply, or condensate and impurities in the cylinder。In this regard, the center of the piston rod should be adjusted;Check whether the oil mist works reliably;Whether the gas supply line is blocked。When there is condensate and impurities in the cylinder memory, it should be removed in time。

(3) The buffer effect of the cylinder is poor, generally due to the wear of the buffer seal or the damage of the adjusting screw。At this time, the sealing ring and adjusting screws should be replaced。

(4) The piston rod and cylinder head of the cylinder are damaged, generally due to the piston rod installation eccentric or the buffer mechanism does not work。In this regard, the central position of the piston rod should be adjusted;Replace the buffer seal or adjusting screw。
