Seal ring standards by the cross section can be divided into O type sealing ring, star type sealing ring, X type sealing ring, sealing ring, V type sealing ring, L type sealing ring, U type sealing ring, Y type sealing ring, sealing ring, sealing ring. According to the material can be classified as nitrile rubber sealing ring, natural rubber sealing ring, chloroprene rubber sealing ring, EPDM rubber sealing ring, hydrogenated nitrile rubber sealing ring, silicon rubber sealing ring, fluorine rubber sealing ring, silicon and fluorine rubber sealing ring. Sealing ring standard is ID diameter *CS wire diameter.
Sealing ring device requires that the sealing ring is the most important and effective means to solve the leakage problem of the hydraulic system. If the sealing ring is bad, the sealing ring may not allow leakage, the leakage of oil will pollute the environment, but also may cause the air to enter the oil absorption cavity, the hydraulic pump performance and the hydraulic performance of the hydraulic performance. Therefore, rational selection and design of sealing ring of the device is very important in the design of the hydraulic system, the seal ring device requirements are as follows: < br / > 1 sealing ring in the working pressure and a certain temperature range, should have a good sealing performance, and with the increase of pressure can automatically improve the sealing performance.
2 the friction between the sealing ring device and the moving part is small, and the friction coefficient is stable.
3 sealing ring has a strong anti-corrosion ability, not easy to aging, long working life, good wear resistance, and can automatically compensate for a certain degree of wear.
4 simple structure, easy to use, easy maintenance, so that the sealing ring has a longer life.
