在以水作为动力液介质的液压抽油系统中,常规的O型密封圈及其他密封圈都不能满足高、低压流体之间不串通的密封要求.设计了一种新型的哑铃型密封结构,并分析其密封机制;利用有限元软件分析在液体压力作用下密封圈的接触变形、接触密封界面上的接触应力分布.结果表明,设计的哑铃型密封结构可以满足要求液压抽油系统16 MPa压差的密封要求.

In the hydraulic oil pumping system with water as power fluid,the conventional O-ring and other sealing rings cannot meet the sealing requirements of not collusion for high and low pressure fluid. A new type of dumbbell-shaped seal ring was designed and its sealing mechanism was analyzed. The contact deformation and the contact stress distribution on the contact sealing interface under the action of the liquid pressure were analyzed by finite element analysis software. The results show that the designed dumbbell-shaped sealing structure can meet the sealing requirements of 16 MPa differential pressure of the hydraulic oil pumping system.
