单螺杆泵转子表面的磨损是造成该种泵失效的主要原因。本课题在研究单螺杆系转子磨损失效机理的基础上，探讨了几种可行的表面修复方法，通过大量的试验研究，确定了单螺杆泵转子磨损表面的金属刷镀修复工艺，为解决生产实际问题提供了可靠途径。
Single screw pump rotor surface wear and tear is the main reason for failure of the pump. Based on the study of the wear failure mechanism of the single-screw rotor, several feasible methods of surface repair are discussed in this paper. Through a large number of experimental studies, the metal brush plating repair process of the single screw pump rotor wear surface is determined. The problem provides a reliable way.
