Seal is known to all the main role is to prevent leak, so a lot of people find vacuum seal, not leaking is qualified, but the seals as the important role of mechanical equipment, not just that simple. Seal told a group of qualified seal you need to meet the conditions: 1, the first material is close-grained, not easy to leak working medium or material, because the seal itself role is to prevent leakage. 2, working medium for the seals have a good adaptability and stability. 3, with the proper mechanical strength and hardness, almost not affected by the influence of working medium, because of different material seal response to different working conditions is not the same. 4, seal good compressibility, permanent deformation is small. 5, good temperature adaptability, high temperature softening, decomposition of low temperature hardening. 6, small friction coefficient, good abrasion resistance. 7, good corrosion resistance, high temperature softening, don't break, low temperature hardening, not brittle. 8, and the sealing surface of joint flexibility and good elasticity. 9, seal good ozone resistance and aging resistance, long service life. Seal 19 years of development, production experience, with a group of professional technical engineers, can according to customer demand for the customer design suitable seal; The finished product is through experimental test, the machine inspection, artificial one by one review three product checking procedure, ensure the quality of the product.
