结合管口应力校核浅析旋转设备的管道设计

Brief Analysis of Piping Design of Rotating Equipment Combined with Nozzle Stress Check

旋转设备管口允许受力载荷较低,给应力分析工程师造成了较大的工作难度。本文根据多年应力分析经验,以离心泵为例,结合离心泵管口应力校核,对降低离心泵管口受力载荷提出了管道设计中的一些建议和方法。

The allowable load on the nozzle of rotating equipment is relatively low,which causes great difficulty for the stress analysis engineer.Based on years of stress analysis experience,taking centrifugal pump as an example,combined with stress check of the centrifugal pump nozzle,some suggestions and methods in piping design are put forward to reduce the load on the nozzle of centrifugal pump.
