Hydraulic Seals Lip Seals

Hydraulic Seals classification lip seal Currently, ceramic factory hydraulic machinery hydraulic cylinders used in combination seals mainly by the ○-ring seals and the square, U-ring, Y-ring, YX-ring and preferably V-ring V-ring sealing performance of other special shapes superimposed on the use of hydraulic seals formed, can be used to determine the number of seals in accordance with the size of the working pressure, they are normally required to be compensated by adjusting the gland the amount of wear of seal rings, its Achilles heel is the structure of complex, often shall support ring, ring and pressure ring of three parts, the larger and with increasing work pressure and seal friction and increased in number. Therefore, only the V-ring adapted to lower velocity and higher working pressure of the hydraulic cylinder adopted. U-ring U-ring seal performance is better, but is easy to roll alone, so be with bronze bearing ring supporting the use of quality, its large and increasing friction with increasing working pressure. So the U-shaped ring only suitable for lower working pressure or lower velocity of the hydraulic cylinder be used. Y Y-shaped seal ring is relying on its opening close to the lip sealing surface and remain sealed, usually can be used alone, preferably the sealing performance, the frictional resistance is small, good pressure resistance, working stability good, long life. Therefore, Y-ring is suitable for high-speed swing, big bore, long stroke hydraulic cylinder use. YX YX-ring-ring is a sectional height to width ratio greater than 2 and work on non-working lip lip unequal height of Y-shaped ring, which is divided into the hole with YX-ring and shaft YX-ring, Like the sealing performance, in addition to all the advantages of having a Y-shaped outer ring, when used alone never YX-ring rolling, to further improve its pressure resistance and job stability. So YX-ring especially suitable for high-pressure, high-speed swing cylinder and rapid movement of adoption. Self-styled compact hydraulic seal: lip seal, with self-sealing pinch-shaped hydraulic seals, as according to its own deformation on the sealing surface higher initial contact stress, no pressure to prevent leakage of fluid. Working hydraulic cylinder, pressure liquid is squeezed and stretched its sealing lip, so close contact with the sealing surface and generate additional stress with high pressure fluid pressure increased and increased, and with the initial contact stress together to prevent pressure leakage of the liquid. Commonly used a combination of seal hydraulic cylinder seals mainly bud-ring, Georgia to circle and Lancaster closure. 1: Lei Lei-ring-ring is usually made of a synthetic rubber ring ○ quality cloth and a rubber ring superposition of Y use configuration, and self-sealing pinch hydraulic seals and self-styled compact hydraulic seals, as lip seals, according to its own deformation on the sealing surface higher initial contact stress, no pressure to prevent leakage of fluid. When the cylinder operating pressure of the liquid through the ring ○ always squeezed and stretched elastic deformation Y-ring seal lips, so close sealing surfaces and produce higher with pressure liquid pressure increased and increased Additional contact stress and contact stress together with the initial pressure of the liquid to prevent leakage. 2: cell to ring grid to circle usually made of synthetic rubber qualitative ○-ring and a square ring filled PTFE quality superposition use constituted, it can be divided into hole grid to ring and the shaft by lattice circle, but its sealing function is the same, according to its own deformation on the sealing surface higher initial contact stress, no pressure to prevent fluid leakage. Hydraulic cylinder working pressure of the liquid ring by elastic deformation ○ start squeezing the maximum square ring, so close contact with the sealing surface and generate additional stress with high pressure liquid pressure increased and increased, and with the initial contact stress together to stop the leak pressure liquid. 3: Stepseal Stepseal generally rectangular shape is made of special synthetic rubber qualitative ○ ring with PTFE quality - trapezoidal ring composed with the same cell to circle divided into hole Manchester Manchester seal and shaft seal, the seal and sealing mechanism of cell to circle the same, but it only has a one-way seal. Self-styled compact hydraulic seal: lip seal, the smaller the area of ??contact with the sealing surface of the lip close fit, it can have a greater compressive deformation, to obtain a better seal. But easy to wear, which wear after sealing action significantly reduced with the use of a ring ○ superposition use, i.e. when the combination seal lip wear even after, since synthetic rubber ○ ring having greater flexibility, it It will force the lip seal lip against the sealing surface, a large enough surface contact stress, achieve sealing effect, and friction is small, smooth, and easy assembly and maintenance. Accordingly, the hydraulic seals currently automatic hydraulic press, household ceramics, plates, dishes type isostatic pressing machine and pressure grouting, pressure grouting sanitary ceramics molding machine is widely used in almost all combinations of seals, As grid to circle and Manchester ring.
