Analysis and troubleshooting methods of common cylinder faults

1. Accident phenomenon: external leakage.
External leakage can be divided into air leakage at the piston rod end, air leakage between the cylinder barrel and the cylinder head, air leakage at the buffer adjustment area, etc.
Cause Analysis:                                                                                                         Troubleshooting methods
1) Installation of the piston rod eccentrically

2) Insufficient supply of lubricating oil 2) Check whether the oil mist device is malfunctioning

3) The piston seal is worn 3) Replace the seal

4) There are impurities on the mating surface of the piston rod bearing 4) Clean and remove the impurities, and install and replace the dust cover

5) The piston rod is damaged 5) Replace the piston rod

2. Accident phenomenon: internal leakage.
Internal leakage is generally caused by air leakage from both ends of the piston.
Cause analysis:                                                                                                                        Troubleshooting method:
1) The piston seal is damaged 1) Replace the seal

2) Poor lubrication &nbs
