Operation control method for multi-pump parallel constant-pressure water supply system
The invention provides an operation control method for a multi-pump parallel constant-pressure water supply system, which comprises the following steps of: S1, operating the system at a set lift H0, and monitoring the total flow Qt of a water outlet of the system in real time; s2, when the total flow Qt is increased, the single-pump efficiency eta is calculated, and eta nlt is judged; if yes, adding one water pump to operate, and if not, continuing to operate according to the current number of water pumps; or when the total flow Qt is reduced, the single-pump efficiency eta is calculated, and eta nlt is judged; if yes, one water pump is reduced to operate, and if not, the water pumps with the current number continue to operate. According to the scheme, the current single pump efficiency is calculated and compared with the single pump efficiency after pump addition/reduction, and the automatic pump addition/reduction logic is executed according to the comparison result, so that compared with the traditional method for executing pump addition/reduction by setting the operation frequency, the system is always maintained to work in a high-efficiency area, and the energy consumption of the system is reduced.
本发明提供一种多泵并联恒压供水系统运行控制方法，其包括：S1：系统在设定扬程H0下运行，并实时监测系统出水口的总流量Qt；S2：当总流量Qt变大时，计算单泵效率η并判断ηn<ηn+1是否成立，若成立，则增加一台水泵运行，否则继续以当前数量的水泵运行；或当总流量Qt变小时，计算单泵效率η并判断ηn<ηn‑1是否成立，若成立，则减少一台水泵运行，否则继续以当前数量的水泵运行。本方案通过计算并比较当前的单泵效率与加/减泵后的单泵效率，并根据比较结果执行自动加减泵逻辑，与传统的通过设定运行频率来执行加减泵相比，使系统始终维持在高效区工作，降低系统能耗。
