GB/T 15613.2-2008 Model acceptance tests of hydraulic turbines storage pumps and pump-turbine - Part 2: Main hydraulic performance test (English Version)
1 Scope
This part of GB/T 15613 applies to laboratory models of any type of impulse or reaction hydraulic turbine, storage pump or pump-turbine.
This part applies to models of prototype machines either with unit power greater than 10MW or with nominal diameter greater than 3.3m. Full application of the procedures herein prescribed is not generally justified for machines with smaller power or diameter. Nevertheless, this part may be used for such machines by agreement between purchaser and supplier.
In this part, the term "turbine" includes a pump-turbine operating as a turbine and the term "pump" includes a pump-turbine operating as a pump.
This part excludes all matters of purely commercial interest, except those inextricably bound up with the conduct of the tests.
This part 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.
