摘　　要：输送高温高压的介质时,需要对离心泵口进行详细的管道应力分析。在管口计算受力不能满足泵口许用受力的要求时,需要增加管道长度来提升管道自补偿能力。如何有效增加管道长度提高管道柔性是本文探讨的核心。本文用CAESAR Ⅱ软件建模,对计算结果进行分析,并利用经验公式进行计算,有效地指导管道走向。对原始管道经过两次再设计,使管口受力满足要求。Centrifugal pump nozzles required de tailed stress analysis, especially during transferring media with high temperature and high pressure. Normally, the length of the pipe is increased to enhance the flexibility of the pipeline. How to increase the pipe length effectively is the core of the discussion. The CAESAR II software is used to analyse the calculation results, and the empirical formula is used to calculate, in order to effectively guide the pipes. After two redesigns, the force and moment of the nozzles meets the requirements.
