水轮发电机组在安装位置校动平衡的方法很多,近来多采用“三次试加重法”。这个方法作图(或配合计算)求解比较准确可靠。其具体步骤可见水电部第十二工程局富春江水工机械厂编写的《水轮发电机校动平衡》和武汉水利电力学院编写的《水力机组安装与检修》讲义中有关章节。这个方法对其振动值的测量方法要求不甚严格,可用百分表或简单的测振仪进行振动值的测量。但是它由于要分别装、拆试重三次起动机组,
There are many ways to balance the hydro-generating set at the installation site. Recently, the “three-try-plus-weight method” has been widely adopted. This method of mapping (or with the calculation) to solve more accurate and reliable. The specific steps can be found in the twelfth Engineering Bureau of the Ministry of Water Resources Fuchunjiang Hydraulic Machinery Plant prepared by the “hydro-mechanical balance” and water conservancy and Electric Power Institute of Wuhan prepared “installation and maintenance of hydraulic units” in the relevant chapters. This method of measuring the vibration value of its less stringent requirements, you can use a dial indicator or a simple vibration meter vibration measurement. However, it is due to be installed separately, demolition test three times to start the unit,
