在进行机组甩负荷试验时,预先必需知道水轮机调节保证计算值。其中关于计算水锤升压的常用公式。有摩尔根史密斯公式、列宁格勒金属工厂公式等,近来常采用《水轮机设计手册》中的公式。经实测证实,蜗壳压力上升实测值一般均大于计算值,具体试验数据可参见水电部长沙勘测设计院《一九六五年调节保证试验总结报告》。使用上
When carrying out unit load shedding test, it is necessary to know in advance the calculation of turbine regulation guarantee. One of the commonly used formula for calculating water hammer boost. There are Morgan Stanley formula, Leningrad metal factory formula, etc., recently used “turbine design manual” formula. The measured results confirmed that the volute pressure rise measured values are generally greater than the calculated value, the specific test data can be found in the Ministry of Water Resources Changsha Survey and Design Institute “1965 Regulation Guarantee Test Summary Report.” Use on
