The Cylinder Repairment In The Anodized Aluminum Window Frames

Outside leakage

1. Leakage between piston rod and the front cover

Reason: the piston rod installed eccentric; lack of lubricating oil; between piston rod and seal has impurities; seal aging damage; piston rod with scars

Method: re-install the adjustment; check whether the oil mist is malfunctioning; clean, remove impurities; repair the seal; repair the piston rod

2. Leakage between cylinder and end cap

Cause: The connection thread is loose; the seal is damaged

Method: Re-tighten; replace the seal

3. Buffer throttle leakage

Cause: Seal aging damage

Method: Replace the seal

4. Inside leakage

Pistons’ air run at both ends

Reason: poor cylinder lubrication; sealing surface debris; seal aging damage

Method: Check whether the oil mist is malfunctioning; clean and remove impurities; replace the seal

5. Cylinder output is insufficient

Reason: serious internal and external leakage; load mechanism is not flexible; low working pressure; load capacity of large bore

Method: troubleshoot by internal and external leakage; re-adjust the installation; increase the working pressure; improper selection is not suitable

6. Piston rod damage

(1) surface pull marks

Cause: The piston rod is eccentric; there is a debris between the rod and the seal

Method: polish and repair by sandpaper; replace the piston rod

(2) bending fracture

Reason: eccentric load or lateral load; bear the impact load

Method: Eliminate the eccentric load and lateral load; set the buffer device

Buffer effect is not good

Cause: The cushion seal is not good; the needle stem is damaged; the cylinder is too fast

Method: replace the buffer ring; replace the needle stem; reduce the speed.

7. Cylinder strain

Reason: poor cylinder lubrication; cylinder with debris
