1. Components of Piston Rod Seal:
Polyurethane, polyformaldehyde, rubber
2. Purpose and function of piston rod Seal:
The rod seal belongs to the dynamic seal. It is the seal that moves with the piston rod. It is one of the important components on the hydraulic support.
3. Use position of piston rod seal:
Guide sleeve, piston
4. Working principle of piston rod seal:
It is used at the contact part between the guide sleeve and the outer cylinder to seal the emulsion in the outer cylinder.
5. What effects will be caused by improper use or operation of piston rod seal:
1. Improper selection of cavity support material will wear the cavity and piston rod.
2. The size of the friction pair is inappropriate, causing wear.
3. Improper thread guide angle of cylinder barrel and piston end wear the Sealing ring.
4. The seal ring is worn due to improper installation guide angle of the seal.
5. The surface of cavity and piston rod is rough, with scratches and worn seals.
6. The outer cylinder leaks and the jack does not maintain pressure.
