In order to clarify the hydraulic performance of the submersible tubular pump device in Yangzhou Gate Pumping Station, the internal flow and hydraulic performance of the submersible tubular pump device were analyzed by numerical simulation combined with physical model test. The influence of the front and rear bulbs body on the energy performance of the pump device was compared and analyzed through the comprehensive characteristic index C.P.I, and the scheme of the submersible tubular pump device with the rear bulb body was optimized. The maximum efficiency of the submersible tubular pump device with the rear bulb body is 78.86 %, the flow rate is 314.86 L/s, the lift is 3.594 m, and the blade placement angle is +2°. When the blade angle is -4°, the runway speed of the prototype pump device is 295.19 r/min, which is 1.75 times the rated speed of the prototype pump device. The streamline of straight pipe inlet is smooth under each flow rate conditions, the local area of guide vane appears backflow and the spiral flow inside straight outlet conduit is obvious under small flow rate conditions. With the increase of flow rate, the proportion of hydraulic loss of bulb body and outlet conduit decreases firstly and then increases, and the proportion of hydraulic loss of bulb body and outlet conduit in the whole flow conduits of pump device is the largest. The research results can provide reference for pumping station engineering.

为明晰扬州闸泵站潜水贯流泵装置的水力性能,采用数值模拟结合物理模型试验的方法分析该潜水贯流泵装置内流及水力性能,通过综合特性指标C.P.I对比分析了前后置灯泡体对泵装置能量性能的影响,优选了灯泡体后置的潜水贯流泵装置方案,灯泡体后置的潜水贯流泵装置最高效率达78.86%,此时流量为314.86 L/s,扬程为3.594 m,叶片安放角为+2°。在叶片安放角为-4°时,原型泵的飞逸转速达295.19 r/min,该飞逸转速为原型泵额定转速的1.75倍。各流量工况时直管式进水流道流线平顺,小流量工况时导叶体局部区域出现了回流且直管式出水流道内部螺旋状水流明显。随着流量的增大,灯泡体和出水流道的水力损失占比呈先减小后增大的趋势,灯泡体和出水流道占泵装置整个流道的水力损失比例最大。研究结果可为工程实践提供参考。

为明晰扬州闸泵站潜水贯流泵装置的水力性能,采用数值模拟结合物理模型试验的方法分析该潜水贯流泵装置内流及水力性能,通过综合特性指标C.P.I对比分析了前后置灯泡体对泵装置能量性能的影响,优选了灯泡体后置的潜水贯流泵装置方案,灯泡体后置的潜水贯流泵装置最高效率达78.86%,此时流量为314.86 L/s,扬程为3.594 m,叶片安放角为+2°。在叶片安放角为-4°时,原型泵的飞逸转速达295.19 r/min,该飞逸转速为原型泵额定转速的1.75倍。各流量工况时直管式进水流道流线平顺,小流量工况时导叶体局部区域出现了回流且直管式出水流道内部螺旋状水流明显。随着流量的增大,灯泡体和出水流道的水力损失占比呈先减小后增大的趋势,灯泡体和出水流道占泵装置整个流道的水力损失比例最大。研究结果可为工程实践提供参考。

In order to clarify the hydraulic performance of the submersible tubular pump device in Yangzhou Gate Pumping Station, the internal flow and hydraulic performance of the submersible tubular pump device were analyzed by numerical simulation combined with physical model test. The influence of the front and rear bulbs body on the energy performance of the pump device was compared and analyzed through the comprehensive characteristic index C.P.I, and the scheme of the submersible tubular pump device with the rear bulb body was optimized. The maximum efficiency of the submersible tubular pump device with the rear bulb body is 78.86 %, the flow rate is 314.86 L/s, the lift is 3.594 m, and the blade placement angle is +2°. When the blade angle is -4°, the runway speed of the prototype pump device is 295.19 r/min, which is 1.75 times the rated speed of the prototype pump device. The streamline of straight pipe inlet is smooth under each flow rate conditions, the local area of guide vane appears backflow and the spiral flow inside straight outlet conduit is obvious under small flow rate conditions. With the increase of flow rate, the proportion of hydraulic loss of bulb body and outlet conduit decreases firstly and then increases, and the proportion of hydraulic loss of bulb body and outlet conduit in the whole flow conduits of pump device is the largest. The research results can provide reference for pumping station engineering.
