Problems solved by technology

Each valve has a valve seat, a valve body and a replaceable valve rubber. The valve rubber is a vulnerable part. The erosion and wear of the valve rubber determine the valve structure and the service life of the piston. The valve rubber The damage form is wear and aging, and the valve body and valve rubber will be quickly damaged by the mud. Those skilled in the art urgently need to develop a preparation method for the wear-resistant and corrosion-resistant valve rubber material of the mud pump.

Abstract

The invention belongs to the technical field of high polymer materials, and particularly relates to a preparation method of a wear-resistant and corrosion-resistant valve rubber material for a slurrypump. Chlorinated polyether and acrylate rubber are used for blending modification, and the prepared wear-resistant corrosion-resistant valve rubber material has excellent performance on resisting acid, alkali, muddy water, cement paste and the like. The material has the characteristics of wear resistance, scouring resistance, aging resistance, long service life and the like, and has good tensiletear resistance and high temperature resistance.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to a method for preparing a mud pump wear-resistant and corrosion-resistant valve rubber material. Background technique [0002] The valve assembly is a switch mechanism in the drilling pump that controls the one-way flow of the liquid in the pump. It relies on the hydraulic pressure in the pump to realize the opening and closing of the valve body and the valve seat. It is mainly composed of the valve body assembly and the valve seat. Therefore, those skilled in the art urgently need to develop a preparation method for the wear-resistant and corrosion-resistant valve rubber material of the mud pump. One of the most easily damaged parts of the mud pump is the inlet valve and the outlet valve. Carburizing treatment with the inner diameter. If serious erosion is found during maintenance, it should be replaced in time. The valve rubber in the inlet valve and outlet valve is no...
