Common faults of cylinder and their elimination methods

1. Internal air leakage and blowby usually occur between the front cavity and the back cavity of the cylinder, which are caused by the damage of piston sealing ring, cylinder head and axial sealing ring.

2. External leakage. When working, gas leaks from the inside of the cylinder to the outside. The reasons include the damage of the sealing ring of the dust-proof ring, impurities on the surface of the shaft center, deformation of the cylinder barrel and other fault problems.

3. Poor and unsmooth operation, which is caused by problems such as shaft and load link, mismatch between fittings, cylinder deformation, etc.

4. Bad buffering, damaged, unsmooth and deformed buffering surface, sealing ring and screw cone.

5. Bending fracture of piston rod is caused by deformation or damage of buffer sealing ring, screw cone surface and hole cone surface.

6. The cylinders are out of sync. The reason for the failure is that the output pipeline is not the same length, the friction coefficient of the cylinders is different, and the speed regulating throttle valve is not installed during installation.

7. Insufficient output force, such as insufficient air supply pressure, greater load force than cylinder, air leakage of cylinder, etc.
