摘要(Abstract):

探讨了ISO 9906和GB/T3216-2005标准中有关流量、扬程和效率值以及NPSHR的判定问题。以标准中性能保证值判定为基础,分析了标准中性能满足的保证条件,分别提出了流量、扬程和效率值以及NPSHR的判定的数学表达式,解决了计算机辅助试验中计算机判定的技术难题。同时,比较了新、旧的判别方法,为进一步理解和贯彻实施这些标准将会起到积极作用。
It has been researched on the verification about the value of capacity,head and efficiency and NPSHR in the ISO9906 and GB/T3216-2005.Based on the guarantee value of performance in the standard,the guarantee condition satified by the performance was analyzed in the standard,and the mathematical expressions about the value verification of capacity,head and efficiency and NPSHR respectively were presented,so that the technical problem on the verification by computer in the computer aided test has been solved.The verification methods in the old and new standard have been compared at the same time.In this way,it will take an active function to understand and excute the those standard.
