摘要
针对空调水系统,基于水泵性能曲线和管网特性曲线,分析了水泵选型是否需要考虑扬程和总流量的富裕量以及并联水泵选型是否要对额定流量进行附加;讨论了确定管网增加并联水泵运行台数导致总流量衰减和减少并联水泵运行台数有可能导致超载;阐述了水泵变速调节,系统流量的影响因素及变化规律。
In view of air-conditioning water system, based on the pump performance curve and the pipe network characteristics curve, whether the head and the total flow affluence need to be taken into account and whether the additional to the rated flow should be considered for parallel pump selection are analyzed;the total flow decay due to increasing the number of parallel pumps operating in the pipe network and the overload due to decreasing the number of parallel pumps operating are discussed;the influencing factors and change laws of the system flow due to variable speed regulation of pumps are elaborated.
