变频调速泵在成品油管道输送中的优势

Advantages of Variable-speed Pump in Oil Product Transportation

分析了成品油管道输送的特点及管道流量、摩阻、扬程等参数的特性,以兰成渝成品油管道成都—重庆段为例,介绍了变频调速泵的功能,认为变频调速泵可以代替调节阀工作,具有流量-扬程范围宽、适应性强的优势,且工作点可以根据设定值和管路摩阻的情况而自动调节转速,更适用于成品油输送系统。

Characteristics of oil product pipeline transportation is analyzed, including the properties of operating parameters in flow rate, frictional drag and pump discharge head. Taking Chengdu-Chongqing pipeline section in Lanzhou-Chengdu-Chongqing Oil Product Pipeline as an example, the authors present the function of the variable-speed pump and think that it can be worked to substitute governing valve,with the advantages of wide work scope in flow rate-discharge head and better suitability,and its rotary speed can be automatically changed based on set parameters and frictional drag of pipeline, which is more suitable for the pipeline system of oil product transportation.
