摘要
浙江仙居抽水蓄能电站发电电动机单机容量375MW,额定转速375r/min。本文介绍了仙居电站发电电动机镜板泵外循环系统理论、结构与试验验证,及实际运行中镜板泵集油槽密封故障的处理。高速机组镜板泵具有泵压高的特点,需要加强泵的密封及密封结构的强度,进一步提高泵密封结构的可靠性。
The rated speed of the Xianju pumped storage power station generator motor is 375r/min, and its rated unit capacity is 375MW. This paper introduces the runner pump theory, structure, the verification test on the thrust bearing test rig, and the solution to seal failure in the equipment operation. The high-speed runner pump pressure is high. To further improve the reliability of the pump seal structure, so it is necessary to improve the sealing performance and its strength.
