Mute method for preventing dormancy of submerged water pump in secondary water supply system
The invention provides a mute anti-flooding pump dormancy method in a secondary water supply system, which comprises the following steps: S1, only one pump in the secondary water supply system works, and the water outlet pressure of the secondary water supply system reaches the target pressure and is kept unchanged; s2, the actual output power P1 of the pump is obtained, and the dormancy power P of the pump is calculated by combining the actual output power P1 with the rated output power P2 of the pump; s3, judging whether the output efficiency eta of the pump is smaller than the sleep power P or not, and if yes, enabling the pump to automatically sleep after sleep delay; otherwise, not sleeping. According to the scheme, the comparison result of the dormancy power P calculated according to the actual output power P1 and the rated output power P2 and the output efficiency eta serves as the basis for judging whether the pump is dormant or not, and the situation that when the pump is controlled to be dormant through the set dormancy frequency in the prior art is avoided; the situation that the frequency converter does not sleep at night due to the fact that the operation frequency of the frequency converter is higher than the sleep frequency occurs, and the secondary water supply system operates more reliably at night.
本发明提供一种二次供水系统中静音防淹水泵休眠方法,包括:S1:二次供水系统中只有一台泵工作,二次供水系统出水压力达到目标压力并维持不变;S2:获取泵的实际输出功率P1,并结合泵的额定输出功率P2计算泵的休眠功率P;S3:判断泵的输出效率η是否小于休眠功率P,若小于,经过休眠延时后,泵自动休眠;否则不休眠。本方案将根据实际输出功率P1和额定输出功率P2计算得到的休眠功率P与输出效率η的比较结果作为判断泵是否休眠的依据,杜绝了现有的通过设定的休眠频率控制泵休眠时,会出现由于变频器的运行频率高于休眠频率导致的夜间不休眠的情况发生,使得二次供水系统在夜间的运行更可靠。
