为制定适用于反作用水轮机、蓄能泵和水泵水轮机的空化点蚀保证提供了依据。它涉及在给定条件下，对特定机器部件上的气蚀点蚀量的测量和评估，这些条件在合同中通过输出、比水力能（E）、速度、材料、操作等进行定义。气蚀点蚀评估基于给定时间和精确定义的操作条件下的材料损失。 考虑所有湿润表面

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
