电液转换器和放大器是电液调速器中最重要元件,它们的性能好坏直接影响机组运行质量。据不完全统计,因电调故障而影响机组正常运行的,大部分是放大器和电液转换器调整质量不佳而引起的,因此对它们特性的调整和试验是势在必行。而在试验方法上,目前很多参考书上都是设单独电源(将 Electro-hydraulic converters and amplifiers are the most important components of the electro-hydraulic governor, and their performance directly affects the running quality of the unit. According to incomplete statistics, most of the problems that affect the normal operation of the unit due to the failure of the ESC are caused by poor quality adjustment of the amplifier and the electro-hydraulic converter. Therefore, adjustment and testing of their characteristics are imperative. In the test method, many reference books are currently set up a separate power supply (will
