水轮机、蓄能泵和水泵水轮机 模型验收试验

[中文适用范围]： 本国际标准适用于任何类型的脉冲式或反动式水轮机、蓄能泵或水泵水轮机的实验室模型。本标准适用于单位功率大于5MW或参考直径大于3m的样机型号。对于功率和尺寸较小的机器来说，完全应用本文规定的程序通常是不合理的。然而，经买方和供应商同意，该标准可用于此类机器。在本标准中，术语“水轮机”包括作为水轮机运行的水泵水轮机，术语“泵”包括作为泵运行的水泵水轮机。本标准排除所有纯粹商业利益的事项，与测试的进行密不可分的事项除外。该标准既不涉及机器的结构细节，也不涉及其部件的机械性能，只要这些不影响模型性能或模型与原型性能之间的关系即可。 [外文原描述]： IEC 60193:1999 applies to laboratory models of any type of impulse or reaction hydraulic turbine, storage pump or pump-turbine. This standard applies to models of prototype machines either with unit power greater than 5 MW or with reference diameter greater than 3 m. Full application of the procedures herein prescribed is not generally justified for machines with smaller power and size. Nevertheless, this standard may be used for such machines by agreement between purchaser and supplier. In this standard, the term "turbine" includes a pump-turbine operating as a turbine and the term "pump" includes a pump-turbine operating as a pump. This standard excludes all matters of purely commercial interest, except those inextricably bound up with the conduct of the tests. This standard is concerned with neither the structural details of the machines nor the mechanical properties of their components, so long as these do not affect model performance or the relationship between model and prototype performances. The main objectives of this standard are: – to define the terms and quantities used; – to specify methods of testing and of measuring the quantities involved, in order to ascertain the hydraulic performance of the model; – to specify the methods of computation of results and of comparison with guarantees; – to determine if the contract guarantees, which fall within the scope of this standard, have been fulfilled; – to define the extent, content and structure of the final report. The guarantees can be given in one of the following ways: – guarantees for prototype hydraulic performance, computed from model test results considering scale effects; – guarantees for model hydraulic performance.
