溧阳球阀接力器开启时间过长问题研究与试验

Research and Test of Too Long Opening Time Problem about Liyang Spherical Valve Servomotor

溧阳抽水蓄能电站在6#机球阀安装结束后进行了无水调试试验,试验过程中出现了球阀开启时间较长的问题。经过现场对试验数据的研究和对球阀接力器结构尺寸的计算,在对球阀接力器结构进行优化改进之后,6#机球阀的开启时间达到了球阀开启时间的要求。

An anhydrous test was conducted after installation of No. 6 machine spherical valve in Liyang pumped- storage power station,appearing a problem that opening time of spherical valve was too long during the test. Through researching the test data on-site and calculating the dimension of spherical valve servomotor structure,the opening time of No. 6 spherical valve reached the demands for spherical valve opening time after the servomotor structure of spherical valve was optimized and improved.
