摘要
针对简单的采用“横加法”来确定因分支管路长度以及各水泵入口点高差的不同,给各并联水泵运行工作点带来的影响进行了理论分析;同时给出了在考虑这些影响因素后各泵真实工作点的确定方法,为并联系统中水泵的合理选择和正确操作提供可参考的依据。
The affects on every parallel connection pump working point are theory, analyzed, which are cansed by using the simply ＂borizontal addition ＂to make sure of the differences of both branch pipe length and every pump intake level;A certain method to confirm ev- ery pump real working point after considering these factors of influence was pointed out. some reference evidences for reasonably choosing and correctly operating the pump in parallel connection system are offered.
