摘要
本文在肯定IEC60193的同时,指出了其存在的部分问题,并结合新修订的国家标准对这些问题加以修正,从水轮机公称直径的定义、流道测量偏差要求的表述及空化系数定义等三个方面提出了比较符合中国实际的定义或表述。
This paper affn-ms the achievements of the IEC 60193, meanwhile, it points out some problems which exist in it, and considering the amendment by the New Chinese National Standard. It puts forward the definition or description which is in accord with actual situation of China from the three aspects of the definition for nominal diameter of the hydraulic turbines, the statement for requirement of the water passage flow measurement deviation and the definition of the cavitation sigma.
