| 摘 要： | 利用泵站现场管路条件，对镇江市江滨泵站6号泵进行了单泵实际水力特性测试。用数据分析了该泵站的运行状况，指出在单泵和双泵全速运行时。流量会分别偏离设计点近1．4和1.2倍，使实际汽蚀余量低于临界汽蚀余量。水泵运行在遭受汽蚀危害的状态；而且运行时扬程高于泵站需要的装置扬程。造成能源浪费。通过对该泵站水泵运行的分析，提出了4点改进的途径。

| Abstract: | By using the field pipeline, the hydraulic characteristics of the No.6 pump is measured, which is set in Zhenjiang Jiangbin pumping station. The operation condition of this station is analyzed, when one pump or two pumps run at full speed, the flow rate deviate from the design one by nearly 1.4 and 1.2 times, and the real NPSH was lower than the critical one, which result in cavitation in pump; and the water head is higher than needed, which cause energy waste. Four improvements were proposed based on the results. |
