Application of ultra-high pressure seal

Ultra-high pressure seals are also divided into static seals and dynamic seals. With the development of sealing technology, new materials, new structures and special processes have been developed. Products with high technical content, ultra-high pressure resistance, long life, low friction, and no leakage. If according to the composition of the hydraulic system, the ultra-high pressure seal is divided into pipeline seal and hydraulic component seal, hydraulic cylinder, hydraulic motor, hydraulic pump, hydraulic valve and so on are common in hydraulic components.

ultra high pressure sealIt is also divided into static sealing and dynamic sealing. With the development of sealing technology, there are now new materials, new structures and special processes. The products have high technical content, and have the characteristics of ultra-high pressure resistance, long life, low friction, and no leakage. The product came out. If according to the composition of the hydraulic system, the ultra-high pressure seal is divided into pipeline seal and hydraulic component seal, hydraulic cylinder, hydraulic motor, hydraulic pump, hydraulic valve and so on are common in hydraulic components.

Hydraulic pumpultra high pressure sealMainly using reciprocating dynamic seal, this structure sealing pressure can reach 600 ~ 700MPa ultra-high pressure sealing effect. For hydraulic cylinders, if the rated working pressure of the design and manufacture exceeds 65MPa, it is very difficult not to use foreign seals when the maximum pressure resistance of domestic seals generally does not exceed 65MPa before the advent of Che's seals,

The hydraulic pipeline system mainly considers the sealing structure of various joints. For example, the sealing pressure of the flaring joint can reach 80 ~ 100MPa, the sealing pressure of the gasket orifice joint can reach 80 ~ 100MPa, and the pressure of the sealing liquid of the O-ring joint can reach 80 ~ 100MPa, even more than 100MPa. For the valve block process orificeultra high pressure sealIn the hydraulic system, there are many common process holes, especially in the design and manufacture of the whole box valve block process holes, which must be blocked after manufacturing.

With the use of ultra-high pressure technology is expanding, ultra-high pressure hydraulic equipment and test equipment will also be increasing, but one of the important factors affecting the technology is ultra-high pressure seal, if the ultra-high pressure seal is reliable, the safety of the equipment is also greatly improved.
