GRS China Manufacture Nice Quality Cylinder Rotary Hydraulic Oil
Seal
In addition to the general requirements of the sealing ring
material, the sealing ring should also pay attention to the
following conditions:
(1) Full of elasticity and resilience;
(2) Appropriate mechanical strength, including expansion strength,
elongation and tear resistance.
(3) The performance is stable, it is not easy to swell in the
medium, and the thermal shrinkage effect (Joule effect) is small.
(4) It is easy to process and shape, and can maintain precise
dimensions.
(5) Does not corrode the contact surface, does not pollute the
medium, etc.
The most suitable and commonly used material to meet the above
requirements is rubber, so the sealing ring is mostly made of
rubber. There are many types of rubber, and new types of rubber are
constantly appearing. When designing and selecting, one should
understand the characteristics of various rubbers and choose them
reasonably.
Commonly used in the manufacture of reciprocating seals in
hydraulic systems. It is widely used in the sealing of hydraulic
cylinders in construction machinery.
O-ring
Mainly used for static sealing and reciprocating motion sealing.
When used for rotary motion sealing, it is limited to low-speed
rotary sealing devices.
Rectangular sealing ring
It is generally installed in a groove with a rectangular
cross-section on the outer circle or the inner circle for sealing.
Y type sealing ring
It is widely used in reciprocating sealing devices.
In addition, there is a spring tension (spring energy storage)
sealing ring, which is a spring added to the PTFE sealing material,
there are O-shaped springs, V-shaped springs, and U-shaped springs.
