空化性能是水轮机主要性能参数之一。本文介绍了中国水轮机标准化委员会国家标准修订工作组对1995年实行的GB15469《反击式水轮机空蚀评定》标准的修订过程,说明了2008年标准与1995年标准和国际电工委员会IEC60609—1:2004《反击式水轮机、蓄能泵和水泵水轮机空蚀评定》标准的异同。GB15469—2008版标准的贯彻实施将对我国水轮机开发与制造水平起到促进作用。
Cavitation performance is one of the main performance parameters of the turbine. This paper introduces the revision process of China National Standard Revision Committee of Turbine Standardization Committee on the standard GB15469 “Impact Hydraulic Turbine Cavitation Assessment” practiced in 1995, and describes the standards of 2008 and 1995 and IEC60609-1: 2004 Standard of International Electrotechnical Commission The similarities and differences of standards of assessment of cavitation of impact turbine, storage pump and pump turbine. GB15469-2008 version of the standard implementation of the turbine development and manufacturing in China will play a facilitating role.
