It can make the seal effective lubrication and reliably, and must choose China Rubber oil Seal Manufacturers a star ring larger than the axial diameter. Static seal or reciprocating line motion: hole seal: the inner diameter size of the star neck should be related to the trench Adapt, or less than 2% of the outer size of the groove.
Typically smaller seals can meet the needs of static seal, in turn, larger cross-sectional seals should be selected to meet the requirements of the dynamic seal. The shaft seal: the inner diameter dimension of the star system should be equal to or appropriate than the axis outer diameter size 0.
If the diameter of the shaft is selected, the appropriate star seal is selected according to the following criteria 1. 3. Since the pre-compressive tight force generated by the pre-compression can effectively prevent the distortion of the star seal.
In the case of high pressure or large extrusion gap, a rubber material having a higher hardness is required, and the best way to add a PTFE back carriage to prevent high pressure squeezing.
Rotate the seal: the inner diameter of the star-type neck should be 2-5% compared to the sealing axis, as the seal is friction fever when the rotation movement is friction, while the elastomer is heat-retracted.3mm, or the relative axis outer diameter size is 1%, so the sealing ring can be easier to install while obtaining longer Life.
