Causes and solutions of 16 cylinder fault phenomena

Cylinders are prone to leakage, non-action, crawling and other malfunctions during use. The editor will share with you the "Causes and Solutions to 16 Cylinder Malfunctions", hoping to help all users.

Phenomenon 1: There is leakage from the cylinder piston rod.
Cause of failure 1: The guide sleeve and rod sealing ring are worn, and the piston rod is eccentrically worn. Solution 1: Replace. Improve lubrication conditions. Use rails.
Cause of failure 2: The piston rod is scratched or corroded. Solution 2: Replace. Remove condensation water promptly.

Cause of failure 3: There are impurities between the piston rod and the guide sleeve. Solution 3: Remove impurities. Install the dust boot.




Phenomenon 2: Leakage from the buffer between the cylinder block and end cover.
Cause of failure 1: The sealing ring is damaged. Solution: Replace.
Cause of failure 2: The fixing screw is loose. Solution: Tighten.

Cause of failure 3: The sealing ring is damaged. Solution: Replace.




Phenomenon 3: Leakage in the cylinder and air leakage at both ends of the piston.
Cause of failure 1: The piston sealing ring is damaged. Solution: Replace.
Cause of failure 2: The piston mating surface is defective. Solution: Replace.
Cause of failure 3: Impurities squeezed into the sealing surface. Solution: Remove impurities.

Cause of failure 4: The piston is stuck. Solution: Reinstall to eliminate the eccentric load of the piston rod.




Phenomenon 4: The cylinder does not move
Cause of failure 1: Serious air leakage. Solution: See "External Leakage Phenomenon".
Cause of failure 2: No air pressure or insufficient pressure supply. Solution: See "Fault - Air Circuit - No Air Pressure/Insufficient Air Supply in the Air Circuit"
Failure reason 3: The external load is too large. Solution: Increase the operating pressure and increase the bore diameter.
Cause of failure 4: There is lateral load. Solution: Use guide rails to eliminate.
Cause of failure 5: Installation of different axes. Solution: Ensure that the sliding surface of the guide device is parallel to the cylinder axis.
Cause of failure 6: The piston rod or cylinder tube is corroded, damaged and stuck. Solution: Replace and check the sewage device and lubrication condition.
Cause of failure 7: Condensed water, dust, and sludge are mixed in, which increases the movement resistance. Solution: Check whether the air source treatment system meets the requirements.

Cause of failure 8: Poor lubrication. Solution: Check the oil supply amount, lubricator specifications and installation position.




Phenomenon 5: The cylinder occasionally stops moving
Cause of failure 1: Dust mixed in causing the cylinder to get stuck. Solution: Pay attention to dust.

Cause of failure 2: The electromagnetic reversing valve is not reversing. Solution: See "Fault - Valves - Directional valve does not change direction/pilot valve does not change direction".




Phenomenon 6: The cylinder movement is not smooth
Cause of failure 1: Large change in external load. Solution: Increase the operating pressure or increase the bore diameter.
Cause of failure 2: Insufficient air pressure. Solution: See "Fault - Gas Circuit - Insufficient Air Supply in the Gas Circuit".
Cause of failure 3: The air contains impurities. Solution: Check whether the air source treatment system meets the requirements.

Cause of failure 4: Poor lubrication. Solution: Check whether the oil mist device is working properly.




Phenomenon 7: Cylinder crawling
Cause of failure 1: Use the lowest operating pressure. Solution: Increase the use pressure.
Cause of failure 2: Large leakage in the cylinder. Solution: See "Fault—Cylinder—External Leakage".
Cause of failure 3: The air consumption in the circuit changes greatly. Solution: Add a gas tank
