Cylinder Failure-One of the Common Faults of Concrete Mixing Station

Due to improper assembly and long-term use of the cylinder, the pneumatic actuator (cylinder) is prone to internal and external leakage, insufficient output force and unstable action, poor cushioning effect, piston rod and cylinder head damage and other failures.

(1) Internal and external leakage of the cylinder is generally caused by eccentric installation of the piston rod, insufficient supply of lubricating oil, abrasion or damage of the sealing ring and sealing 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. Always check whether the oil mist sprayer works reliably to ensure good lubrication of the actuator; When the sealing 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; When there are scars on the piston rod, replace it with a new one.

(2) The output force of the cylinder is insufficient and the action is unstable, which is generally caused by the piston or piston rod being stuck, poor lubrication, insufficient gas supply, or condensed water and impurities in the cylinder. In this regard, the center of the piston rod should be adjusted; Check whether the oil mist device works reliably; Whether the gas supply pipeline is blocked. When there are condensed water and impurities in the cylinder, they should be removed in time.

(3) The poor cushioning effect of the cylinder is generally caused by the abrasion of the cushioning sealing ring or the damage of the adjusting screw. At this time, the sealing ring and adjusting screw should be replaced.

(4) The piston rod and cylinder head of the cylinder are damaged, which is generally caused by eccentric installation of the piston rod or ineffective buffering mechanism. In this regard, the center position of the piston rod should be adjusted; Replace the buffer sealing ring or adjusting screw.
