竖井贯流泵能量特性试验研究

Experimental Study on Equipment Energy Characteristic for Shaft Tubular Pump

结合江苏某竖井贯流式泵站,对两种不同转轮在相同进、出水流道情况下进行了能量特性试验研究。试验研究表明,竖井贯流式水泵在超低扬程(1～2m)的调水工程中具有很好的水力性能,其模型泵装置的最高效率达69%左右,该项试验研究为今后竖井贯流泵的进一步开发研究获得了良好的开端。

Based on some shaft through flow pumping station,the energy characteristictests are carried out for two different runners at the same inlet and outlet flowconditions.The tests show that the shaft through flow pump has good hydraulicperformance for super-low head (1～2m) engineering, with model pumping stationefficiency 69% maximum which is helpful for its further development..
