Analysis ofAnalysis of hydraulic O-ring

 

With the gap in the cylinder head and the piston rod 0.03 ~ 0.05mm. O-ring seal mounted hydraulic easy extrusion, clamping cylinder working stroke short at 15 ~ 20mm, less seal wear.

 

The axial length of the aperture, hydraulic O-ring seals share the axial width of 7.3mm, and in the middle of the guide and does not affect the carrying capacity.

 

According to field experience, many hydraulic cylinder O-ring seal for the piston rod, cylinder head aperture sliding seals, pressure 3MPa, general use leakage occurs 2 to 3 years after the sudden damage minimal.According to field experience, many hydraulic cylinder O-ring seal for the piston rod, cylinder head aperture sliding seals, pressure 3MPa, general use leakage occurs 2 to 3 years after the sudden damage minimal.

 

O and Y-type combination of mutually complementary, hydraulic O-ring is not easy to suddenly breakdown, easy to wear leakage. Y-leakage is not easy, easy to breakdown. The principle is: Even if the O-ring hydraulic seal after 2 to 3 years of use greater wear, oil pressure P1 through the O-seal, due to the resistance effect of a pressure drop P2, the hydraulic system of the Y-type seal commutation impact effect is greatly reduced, Y-type seal easy breakdown, oil leakage was blocked Y-type seal. Seal persistent strengthening of 4 to 5 times, the elimination of a large number of oil spills caused by the sudden breakdown of the oil seal is possible.
