??Correlation between hydraulic seals

??At present, China produced more messy hydraulic seal performance standards are different, using a hydraulic seal is reliable, reasonable, a great impact on the system. Hydraulic seal structure of the new standards and old standards exist, the reference data are inconsistent experience inconsistent conclusions. Hydraulic seal groove dimensions, hydraulic seal groove surface roughness and hydraulic seal tolerances, materials, etc., pay attention to the correlation between them.

??We note that the seal groove dimensions to solve the problems, often overlook the radial dimension grooves and cylinder plunger or lever radial dimension tolerances associated.

??Groove dimensions can decide elongation of hydraulic seals, hydraulic seals compression ratio. After the hydraulic seal sealed groove cross section subjected to compressive stress elastically deformed. Hydraulic seals by its own elastic force can also act as a seal. Hydraulic seals seals fail prematurely under high pressure reciprocating friction state, the friction heat generated by rubbing Momo will accelerate the thermal deformation of the rubber material aging hydraulic seals, sealing materials as far as possible by the small heat, consider the installation of hydraulic seals get along heat. Film seal off the oil can cause damage to the phenomenon of accelerated wear rate.

??Hydraulic seal because of its small size, simple structure, low cost, process performance, wide range of features, really widely promoted in the sealing device.
