Abstract

The resin piston pairs have been widely used in machinery industry. A prediction method of the resin piston wear is presented. The eccentric wear form and stress of the piston are given. On this basis, the mathematical model of resin piston wear is established. Taking the resin piston wear of the concrete pumping system as an example, the predicted and practical wear amount are compared. The result shows that the prediction error rate of the wear amount is less than 1% which fully meets the engineering requirements. This example shows that the proposed prediction method of resin piston wear is valid. This paper provides a technical support for optimizing structure of resin piston and improving service performance and life of mechanical products.
