水轮机的泥砂磨损,是水电站运行中一个很重要的问题。目前,国内有关单位正结合黄河等多泥砂河流的特点对其进行研究。国外,如苏联、日本、英国等也有不少文献介绍这方面的运行和试验研究情况。本文系根据国外资料,对影响水轮机磨损的主要因素及其磨损方法的推测,介绍一些情况并进行综合评述。 The sand abrasion of the turbine is a very important issue in the operation of the hydropower station. At present, relevant units in China are studying the characteristics of many muddy sand rivers such as the Yellow River. Overseas, such as the Soviet Union, Japan, the United Kingdom and many other literature also introduces the operation and experimental research in this area. In this paper, based on foreign data, the main factors that affect the wear of hydraulic turbine and its wear and tear of the method of speculation, introduce some of the situation and make a comprehensive review.
