?What qualified hydraulic seals

??Hydraulic seals manufacturers tell you: Qualified seal ten essential conditions?

??1. material dense, difficult to leakage of the working medium or material. Because the seal itself role is to prevent leakage.

??2. The working medium has good adaptability and stability.

??3. have suitable mechanical strength and hardness, hardly affected by the working medium. Such as conventional seals are made of nitrile, silicone, EPDM, fluorine rubber and so on. Different materials for different working conditions is not quite the same reaction, such as nitrile material relatively oil resistant, high temperature resistant silicone, resistant to ozone.

??4. The good compression permanent deformation.

??5. The temperature adaptability, does not soften at high temperatures, it does not decompose at low temperatures without hardening.

??6. The friction coefficient, good wear resistance.

??7. good corrosion resistance, does not soften at high temperatures, it does not decompose at low temperatures without hardening, non-brittle fracture.

??8. bonded with the sealing surface softness and elasticity.

??9. For the ozone resistance and good resistance to aging, long service life.

??10. Good processing performance, low prices.

??Hydraulic seals have classified?

??Hydraulic seals manufacturers tell you: According to the structure can be divided into lip seals, combination seals, lip seal structure can be divided according to Lei-ring, T-ring, Y-ring and other derivative products, the overall piston seal (pneumatic), automatic compensation slim compact seal PZ (pneumatic) and the like; a combination of a seal according to the structure can be divided into coaxial combination seal, V-seal combination, a combination of multi-functional compact seals.
