摘要
本文介绍了大型轴流转浆式水轮机原型试验的原理和方法。通过超声波流量计的测流方法,实现了大型水轮机组绝对效率特性的原型测试。通过对纪村水电站原型机组测试结果的分析,确定最优的协联关系曲线,调整机组最佳的运行工况,产生较明显的经济效益。
The principle and method for the prototype test on large-size Kaplan turbine generator unit is introduced herein; with which the prototype test on the characteristics of the absolute efficiency of large-size turbine generator unit is realized through a method of flow rate measurement based on ultrasonic flow-meter. On the basis of the analysis on the test result of the prototype u- nit of Datang Jicun Hydropower Station, the optimal combination curve is determined and the optimal operation condition for the unit is adjusted, and then more obvious economic benefit is obtained as well.
