锅炉给水泵富裕扬程过高的危害

Harm of the Over Affluent Injecting Distance of the Water Pump in Boiler

通过对锅炉给水泵的H—Q曲线及P—Q曲线的研究分析,结论为泵的富裕扬程过高,将使整个系统的效率降低,还会使泵产生气体,发生汽蚀和供水不足,并提出了相应的解决方法。

Through the research and analysis to H - Q and P - Q curves, we come to a conclusion that the over affluent injecting distance of the pump detracts the efficiency of all the system and makes the pump produce gases, thus vapour - rust and insufficiency of water supplying happen. This paper tables a corresponding solution.
