The material of the first described seal ring is the mixture of teflon and carbon fiber.Oil separator can produce a large amount of heats in the time of work, the temperature upper limit that common fluorine rubber can bear is 120 ℃-150 ℃, and the mixture of teflon and carbon fiber wear resistance under the temperature conditions of 80 ℃-200 ℃ is better, make the working life of sealing circle longer, save cost, and can effectively guarantee the stability of sealing.
The uniform ring-type radiating fin that is provided with on the outer wall of described housing.This ring-type radiating fin contributes to the heat producing while leaving oil separator work, thus the working life that strengthens this oil separator.
The material of described housing is steel.Use steel, reduced manufacture cost.
The bearing at the up and down two ends of described running shaft by being arranged on described housing is fixed in described housing.
Compared with prior art, the utility model has the advantage of: saved original copper alloy bushing, through hole is directly set on housing, by oil sealing being set between through-hole wall and running shaft, in fluid because existing gap to cause between through hole and running shaft, let out preventing, simple in structure, reduce difficulty of processing, save manufacture cost, save complicated assembly technology, oil sealing is arranged on adjacent going out between oil pocket simultaneously, strengthen sealing effect, effectively reduce fluid in let out, thereby reduce the pressure loss in oil hydraulic circuit, the efficiency of hydraulic system is guaranteed.
