本标准仅从模型与原型水轮机机何相似的要求,规定了原型水轮机通流部件对水力性能有影响的控制尺寸的精度和通流表面质量。
本标准适用于混流式、轴流式、斜流式和水斗式水轮机。贯流式、斜击式水轮机和水泵水轮机可参照使用。
1. Scope
1.1 Based upon the geometrically similar requirement for the model and prototype hydraulic turbine, the standard stipulates the precision and water passage components surface quality of the prototype water passage components of hydraulic turbine to the hydraulic performance.
1.2 This standard is applicable to Francis turbine, axialflow turbine, mixed flow variable pitch turbine and pelton turbine. Throughflow turbine, angular impulse turbine and pump turbine can consult to this standard.
2. Normative standards
The following normative documents contain provision which, through reference in this text, constitute provisions of this national standard. For dated reference, subsequent amendments to, or revisions of, any of these publications do not apply. For undated references, the latest edition of the normative document referred to applies.
