摘  要：為了解決傳統(tǒng)變頻恒壓供水系統(tǒng)中壓力傳感器帶來(lái)的問(wèn)題，通過(guò)將泵特性?xún)?nèi)置變頻器，設(shè)計(jì)建立了一種無(wú)壓力傳感器的變頻恒壓供水系統(tǒng)。系統(tǒng)取消了對(duì)傳感器的依賴(lài)，實(shí)現(xiàn)了所有部件的真正集成，同時(shí)消除了傳感器故障的風(fēng)險(xiǎn)，增加了可靠性，并且降低了成本與維護(hù)難度。 關(guān)鍵詞：無(wú)傳感器技術(shù)；恒壓供水；變頻調(diào)速；PID Abstract: In order to solve the problems caused by the pressure sensor in the traditional variable frequency constant pressure water supply system, a constant pressure water supply system w[登陸后可查看全文]
