Abstract

Abstract: The seal and friction wear efficiency of the drilling pump piston mainly depended on the contact stress description be-tween the rubber seal ring and the inside hole of cylinder, so the research of contact stress has a realistic and important meaning.In the article, the contact stress description of piston was ob-tained in static and moving process by finite element method.At the same time, the contact stress description was analyzed under changing piston’s size and the pressure.

Key words: drill pump piston, rubber seal ring, contact stress, finite element
