弹性金属塑料瓦运行与技术分析

本对弹性金属塑料瓦（以下简称塑料瓦）的机理作了简要说明，列举了塑料瓦的优点，汇总了我国部分水电站塑料瓦的运行情况，对运行中出现的一些问题作了简要分析，提出了塑料瓦安全运行须注意的几项问题，并着重就塑料瓦面型线如何设计，塑料瓦摩擦损耗是否比钨金瓦低、以及塑料内应否添加填料等问题作了技术分析。

Operation and Technic Analysis of EMP-Segments

his paper briefly introduces the theoretical mechanism of elastic metallic plastic segments(EMP-segments),lists the advantages of EMP-segments,collects operation data for EMP-segments operated in many hydropower stations of China,makes brief analysis for some problems emerged and puts forward some matters needing attention in operation.This paper also makes emphatically the technic analysis for some issues of EMP-segents such as design of surface shape,friction loss of EMP segments in comparison with babbitt segments and stuffing in plastics of EMP-segments.
