曲面铲磨机的液压系统及其周期进给的PC控制

Hydraulic system. for curve relief grinder and its PC control of periodic feed

曲面铲磨机是一种对大型水轮机叶轮表面补焊后进行修磨的设备。本文对其修磨原理、对液压系统的要求及液压系统的设计组成进行了说明，并对其周期进给的ＰＣ控制功能作了实际试验验证，进而指出其实际应用的可能性。

Curve relief grinder is an equipmentfor relief grinding impelled surface of large waterturbine after repairing welding. This paper describes the principle of relief grinding and thedesign of hydraulic system, and experimentallyverifies the function of PC control of periodicfeed, and thus points out possibilities for its actual application.
