摘  要：水泵運(yùn)行電費(fèi)是一筆不小的費(fèi)用，從節(jié)能方面考慮，在既滿足目前生產(chǎn)的條件下可進(jìn)行變頻改造。變頻恒壓供水控制系統(tǒng)通過(guò)測(cè)量的管網(wǎng)壓力，經(jīng)變頻器的內(nèi)置PID調(diào)節(jié)器運(yùn)算后，自動(dòng)調(diào)節(jié)輸出頻率，實(shí)現(xiàn)管網(wǎng)的恒壓供水。 關(guān)鍵詞：設(shè)備改造；恒壓供水；變頻調(diào)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.
