摘要

水力机组相对效率试验采用指数流量代替绝对流量

无法得到速度水头

因此引用的工作水头中往往忽略速度水头

造成试验结果存在误差。本文提出一种新的方法

可以有效地对计算工作水头进行修正

与实际工作水头更为接近

试验结果更为精确。

Abstract

The velocity head can not be obtained because the index flow is instead of absolute flow in relative efficiency test and the velocity head is often neglected in the traditional calculation of working head

which cause some error of test result. This paper presents a new method for the correction calculation of working head which makes the value of computation working head is close to the value of practical working head and the test results are more reliable.
