High-Pressure Sealing Design of Adjustable Pipe Corner Joint
Hydraulic power steering system for medium and heavy duty commercial vehicles has high medium pressure,even reaching 18 MPa,which places high demands on the sealing performance of pipe joint.In Beiqi Foton Motor Co.,Ltd.,there are 3 types of pipe joint seals used for 18 MPa medium pressure at present,including compression sleeve type,copper flat washer type,and copper flat washer vulcanized rubber combination washer type,and there is no pure rubber seal type.In view of this,the literature results were integrated,and a rubber seal design method was proposed,which was combined with a proven copper flat washer pipe joint seal type.Then,the design scheme of high-pressure sealing products for adjustable pipe corner joint has been formed.After sample test and batch verification,it is concluded that the sealing effect of the design scheme is good.
