离心泵出口管线设计压力的选取探讨

Design and Selection of Nitrogen Seal System for Storage Tanks

针对离心泵出口管线设计压力,本文分析了影响该设计压力的主要因素——离心泵吸入侧所连容器最大压力及离心泵进出口最大压差的设计和选择,给出了一种较为合理的计算方法,安全性更高,为工程设计提供了一定参考。

For the design pressure of centrifugal pump outlet pipeline,the max maximum operating pressure for suction side vessel and the maximum pressure difference between the inlet and outlet are main influencing factors.This paper analyzes their design and selection,gives a more reasonable calculation method with higher security and provides a certain reference for engineering design.
