O-ring is a kind of vulcanized rubber sealing ring with annular cross-section, and its cross-section structure is O-ring, so it is called O-ring. Its sealing effect industry widely uses hydraulic press and automatic control principle system software.

#To prevent the O-ring from bending and destroying, what should be paid attention to in the design of the sealing ring?

1. Minimize the surface roughness of the hydraulic cylinder and the surface of the hydraulic cylinder.

2. Sealing rings with similar friction-resistant seals can be used in substitution.

3. The design plan of the inner hole specification and size is well-balanced, and the sealing part should be sufficiently wiped with grease every time during installation;

4. The precision of installing pipe trenches in the same boat needs to be considered from two aspects: convenient production and processing and no distortion;

5. Raise the cross-sectional diameter of the seal. The cross-sectional diameter of the sealing ring for dynamic sealing should generally exceed the specification and model of the static seal. In addition, the sealing ring should be prevented from being used as a seal for a large diameter piston rod;

6. The sealing ring material is made of low friction materials, and the sealing ring can be used to maintain the efficiency of the flat gasket.
