摘  要：水泵運行電費是一筆不小的費用，從節(jié)能方面考慮，在既滿足目前生產的條件下可進行變頻改造。變頻恒壓供水控制系統(tǒng)通過測量的管網壓力，經變頻器的內置PID調節(jié)器運算后，自動調節(jié)輸出頻率，實現(xiàn)管網的恒壓供水。 關鍵詞：設備改造；恒壓供水；變頻調速 Abstract: Water pump running electricity is not a small cost, from the aspect of energy conservation, in both meet the current production conditions can be carried out frequency conversion. Variable frequency constant pressure water supply control sys[登陸后可查看全文]
