房屋建筑的二次增压给水设备可分为二种基本形式,一种是非匹配型,一种是匹配型。匹配型给水设备的特点是:给水泵的供水流量必须按用水系统的流量变化而变化,从而使供、需双方相互匹配。 调频变速泵给水设备是改变水泵扬程的方法,迫使水泵的供水流量按照需方的要求改变,从而达到相互匹配的目的。目前的技术水平尚不允许电机、水泵超过其额定转速的条件运行,因此变速泵给水设备只能在低于额定转速的条
Secondary pressurized water supply equipment for housing construction can be divided into two basic forms, one is a non-matching type and the other is a matching type. The feature of matched water supply equipment is that the water supply flow of the feed water pump must be changed according to the flow rate of the water system, so that the supply and demand sides match each other. FM variable speed pump water supply equipment is a method to change the pump lift, forcing the water pump’s water supply flow to change in accordance with the requirements of the buyer, so as to achieve the purpose of matching each other. The current state of the art still does not allow motors and pumps to operate at more than their rated speeds, so variable-speed pump feedwater equipment can only be operated at speeds below the rated speed.
