摘要:
为检验澡港河泵站扩容工程的双向立式泵装置的水力性能,确保泵站安全可靠运行并高效地发挥经济与社会效益,采用物理模型试验的方法对澡港河泵站扩容工程泵装置性能进行定量分析,研究了澡港河泵站双向立式泵装置能量性能、空化性能与飞逸特性。试验结果表明:澡港河泵站扩容工程双向立式轴流泵装置运行平稳,无不良噪音和振动,水力性能较好。在叶片安放角-4°、扬程2.51 m时,泵装置最高效率为70.1%。在叶片安放角+1°,设计扬程1.82 m时,泵装置原机组流量为20.56 m3/s,必需汽蚀余量为4.06 m,满足泵站设计参数要求。在叶片安放角为-4°、最大扬程3.31 m时,飞逸转速为水泵机组额定转速的1.49倍。
Abstract:
In order to test the hydraulic performance of the bidirectional vertical pump device of the expansion project of the Zaoganghe Pumping Station, to ensure the safe and reliable operation of the pumping station, and effectively play the economic and social benefits, the physical model test method was used to quantitatively analyze the performance of the pump device, and the energy performance, cavitation performance and flow characteristics of the bidirectional pump device of the Zaoganghe Pumping Station were studied. The test results show that the bidirectional vertical pump device of the expansion project of the Zaoganghe Pumping Station runs stably, without adverse noise and vibration, and has good hydraulic performance. When the blade setting angle is -4° and the head is 2.51 m, the maximum efficiency of the pump device is 70.1%. When the blade setting angle is +1° and the design head is 1.82 m, the flow rate of the original pump device is 20.56 m3/s and the necessary cavitation amount is 4.06 m, which meets the design parameters of the pump station. When the blade setting angle is -4° and the maximum head is 3.31 m, the runaway speed is 1.49 times of the rated speed of the pump.
