《GB/T 15469.2-2007水轮机、蓄能泵和水泵水轮机空蚀评定 第2部分：蓄能泵和水泵水轮机的空蚀评定》由TC175（全国水轮机标准化技术委员会）归口，主管部门为中国电器工业协会。
本部分规定了蓄能泵和水泵水轮机在给定条件下(如在合同中规定的功率、水力比能、转速、材料、
运行条件和运行时间等)过流部件因空蚀造成的材料损失的测量和评定方法。
在合同中应规定水力机械在全部或部分运行范围内是否存在空蚀。
无论空蚀是否发生,在合同中都应明确规定空蚀保证值。
本部分中有关电站的描述也适用于蓄能泵站。

Scope

This part specifies the material loss of storage pumps and pump turbines under given conditions (such as power, hydraulic specific energy, speed, materials, operating conditions and operating time, etc. specified in the contract) due to cavitation. Measurement and evaluation methods. Whether there is cavitation in all or part of the operating range of hydraulic machinery should be stipulated in the contract. Regardless of whether cavitation occurs or not, the guaranteed value of cavitation should be clearly specified in the contract. The descriptions of power stations in this section also apply to energy storage pumping stations.
