摘要
针对低比转速化工离心泵存在效率过低,扬程曲线有驼峰,大流量运行时过载,易发生汽蚀,腐蚀严重寿命短5大难题,从提高效率、可靠性和运行寿命的角度进行了分析和研究,给出了相应的设计方法和措施,可为低比转速化工离心泵设计提供参考依据。
Abstract： Focusing on the five vital problems of the low specific-speed chemical centrifugal pupm： low efficiency, camel＇ s hump in a head-flow curve, easy to overload during large flow running, easy to occur Serious cavitations and a short life cause by heavy corrosion, the paper studied from the views of improving efficiency, reliability and running life and gave out the corresponding design methods. These can be used to guide in design the low specific-speed chemical centrifugal pump.
