离心泵被广泛的用在工农业生产上,为了核算抽水成本,就必须了解水泵的抽水量,许多单位都是按水泵铭牌流量来计算水泵的抽水量,这是不准的,这里介绍一简易较准的方法: 根据离心水泵的Q—H特性曲线,知道了水泵运转时的总杨程H,从Q—H曲线上便可得到水泵出水量Q。问题归结到按照水泵的实际工况求H。下面分三种情况来讨论H的计算式 Centrifugal pumps are widely used in industrial and agricultural production. In order to account for pumping costs, it is necessary to understand the pump’s pumping capacity. Many units calculate the pump’s pumping capacity according to the pump’s nameplate flow rate. This is not allowed. Here is a brief introduction. A more accurate method: According to the Q-H characteristic curve of a centrifugal pump, the total Yang Cheng H of the pump is known. From the Q-H curve, the pump output Q can be obtained. The problem boils down to seeking H according to the actual conditions of the pump. The following three situations discuss the formula of H
