in:2008, based on GB/T 15613-1995 and IEC 60193:1999, the standard was divided into GB/T 15613:1-2008 "Hydraulic turbines, storage pumps and pump-turbine model acceptance tests Part I: General regulations", GB/T 15613:2-2008 "Hydraulic turbines, storage pumps and pump-turbine model acceptance tests Part II: Conventional hydraulic performance Test", GB/T 15613:3-2008 "Hydraulic Turbine, Storage Pump and Pump Turbine Model Acceptance Test Part III: Auxiliary Energy Test" and GB/T 10969-2008 "Technical Conditions for Flow Components of Hydraulic Turbine, Storage Pump and Pump Turbine"; --- This is the second revision: Turbines, storage pumps and pump turbines Model Acceptance Test1 ScopeThis document applies to impulse and reaction turbines, storage pumps and pump turbines tested under laboratory conditions: This document is applicable to the models corresponding to prototypes with unit power greater than 5MW or nominal diameter greater than 3m: the provisions of this document Generally speaking, it is not suitable for the procedure to be completely applied to turbines with smaller unit power or nominal diameter: However, if the supply and demand sides agree, such It can also be implemented by reference to hydraulic machinery: In this document, the term "turbine" includes pump-turbines operating as water turbines, and the term "pump" includes pump-turbines operating as water pumps: Except for matters related to trials, this document does not cover matters of purely commercial interest: As long as the structure or parts of the machine do not affect the performance of the model or the relationship between the model and the prototype, then this document does not deal with hydraulic The detailed structure of the machinery does not involve the mechanical properties of the hydraulic machinery components: This document specifies the procedures for verifying whether the main hydraulic performances of turbines, storage pumps and pump turbines meet the contract guarantee values (see 4:2): Matters related to the model acceptance test conducted: If there is any objection to any step of the test, refer to this document, which contains the rules guiding the test and describes the measurement methods taken: The main purpose of this document is to: --- Define the terms and parameters used; --- In order to determine the hydraulic performance of the model, specify the test method and the measurement parameters involved; --- The calculation method of the specified result and the comparison method with the guaranteed value; ---Determine whether the contract guarantee value within the scope specified in this document is satisfied; --- Define the scope, content and structure of the final report: Guaranteed values can be given in one of the following ways: --- Guaranteed hydraulic performance value of the prototype, calculated and obtained according to the model test results after considering the scale effect; ---Guaranteed value of hydraulic performance of the model: In addition, for the design or operation of the turbine prototype, it is also necessary to determine some auxiliary performance data (see 4:4): and Chapter 4 ~ Chapter 6 The requirements for the main hydraulic performance are different, and the information about the auxiliary performance data given in Chapter 7 is only of a suggestion or guiding nature to the user (see 7:1): If the expected conditions of the field acceptance test (see GB/T 20043-2005) cannot verify the guaranteed value of the prototype, it is more recommended to carry out the model acceptance test: IEC 62097:2019 introduces a consideration model and prototype for pump-turbines, Francis turbines and axial-flow turbines Performance conversion method for flow surface roughness: This method requires model and prototype surface roughness data, and when considering the effect between model and prototype Changes in the nED, QED and PED factors are taken into account in rate corrections: However, for the semi-scroll Francis and axial flow turbines, due to the lack of sufficient numbers However, this conversion method has not been fully validated: In addition, IEC 62097:2019 does not apply to accumulator pumps, bucket turbines and diagonal flow water turbine: Therefore, unless there is a special agreement, it can be assumed that the model and prototype are hydraulically smooth flow, according to the given in Appendix D and Appendix I Conversion formulas and program calculations: Appendix E illustrates the scope of application and limitations of the IEC 60193 and IEC 62097:2019 conversion methods: The method of performance transfer from model to prototype needs to be clearly defined in the main hydraulic performance contract: This document is also applicable to model tests for other purposes, such as comparative tests and research and developmental work: ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T
