Advantages:
(1)Good sealing;
(2)Low pressure when the friction is small;
(3)A small amount of wear can be automatically compensated, long service life.
Disadvantages:
(1)One-way effect, two-way fluid seal with a pair of sealing ring, sealing structure is complex, large size. Between the two sealing rings may produce trapped oil, resulting in reverse pressure damage;
(2)The size of the sealing face is large, and the installation groove should be divided. The groove processing is complex.
Primary use:
The utility model is suitable for sealing the piston and the piston rod which require high comprehensive sealing performance.
