Efficiency-Reinforcement Design of Hydraulic Reciprocating Sealing Element Driven by TRIZ Technology Evolution
The efficiency reinforcement technologies of sealing is important for improving sealing’s reliability and effectivity which result in zero leakage. Technology evolution of TRIZ can be used to forecast the future technology in products. These future technologies can guide a designer along the right direction of developing a new product. In this paper, the efficiency-reinforcement principle of hydrodynamic reciprocating sealing is discussed, technology evolution of TRIZ is integrated with the efficiency reinforcement design of hydrodynamic reciprocating sealing element to predict its future structure state. A new cross section shape of reciprocating sealing element corresponding to the predicted structure state is presented. The computational model of the new reciprocating seal element is established with ANSYS, and its stress, strain and pressure distribution are also analyzed. The results demonstrated that the presented seal elemente outperforms the old O-ring seal in efficiency reinforcement capacity.
