Commonly used self-sealing compression type hydraulic seals are mainly O-ring seals, round seal rings and square seal rings, etc. They have the advantages of simple structure, easy manufacture, low cost, etc., so they are widely used in hydraulic transmission systems. Dynamic sealing element and static sealing element. They are typically 10 to 25% radially
compressively deformed in the seal groove and create a high initial contact stress on the seal surface to prevent leakage of pressure free liquid.
When the hydraulic cylinder is working, the pressure liquid squeezes the self-sealing compression type hydraulic seal to further deform it, and generates a large pressure with the pressure liquid on the sealing surface, which is strictly speaking pressure. Increased and increased additional contact stress, together with the initial contact stress, prevents leakage of pressurized liquid. However, when the working pressure is greater than 10Mpa, in order to prevent a part of the synthetic rubber self-sealing type compression type hydraulic seal from being squeezed into the sealing gap and being cut off in the reciprocating motion of the hydraulic cylinder, leakage is required, and the self-sealing pressure of the synthetic rubber is required. A compression resin retaining ring is provided on the pressure side of the tight hydraulic seal, such as a nylon retaining ring, a polyoxymethylene retaining ring and a filled PTFE retaining ring. Since the synthetic rubber self-sealing compression type hydraulic seal has a large compression deformation when working, its static friction resistance is particularly large, and it is usually more than twice the dynamic friction resistance. Such a large static friction resistance in some low-pressure hydraulic transmission systems is bound to cause low-pressure creep and difficult operation, which is why the self-sealing compression type hydraulic seal is rarely used as a dynamic seal.
