标准摘要
[中文适用范围]： 为制定适用于反动水轮机、蓄能泵和水泵水轮机空化点蚀的保证提供基础。它解决了某些特定机器上空化点蚀数量的测量和评估 [外文原描述]： IEC 60609-1:2004 provides a basis for the formulation of guarantees applied to cavitation pitting for reaction hydraulic turbines, storage pumps and pump-turbines. It addresses the measurement and evaluation of the amount of cavitation pitting on certain specified machine components for given conditions, which are defined in the contract by output, specific hydraulic energy (E), speed, material, operation, etc. The cavitation-pitting evaluation is based on the loss of material during a given time and under accurately defined operating conditions. All wetted surfaces are considered
