變頻調(diào)速恒壓供水設(shè)備以其節(jié)能、安全、高品質(zhì)的供水質(zhì)量等優(yōu)點(diǎn)，使供水行業(yè)的技術(shù)裝備水平從90年代初開始經(jīng)歷了一次飛躍。恒壓供水調(diào)速系統(tǒng)實(shí)現(xiàn)水泵電機(jī)無級調(diào)速，依據(jù)用水量的變化自動(dòng)調(diào)節(jié)系統(tǒng)的運(yùn)行參數(shù)，在用水量的變化自動(dòng)調(diào)節(jié)系統(tǒng)的運(yùn)行參數(shù)，在用水量發(fā)生變化時(shí)保持水壓恒定以滿足用水要求，是當(dāng)今最先進(jìn)、合理的節(jié)能型供水系統(tǒng)。
變頻恒壓供水自動(dòng)控制系統(tǒng)工作原理如下：
系統(tǒng)正常運(yùn)行時(shí)，用戶用水管網(wǎng)上的壓力傳感器對用戶的用水水壓進(jìn)行數(shù)據(jù)采樣，并將壓力信號轉(zhuǎn)換為電信號，傳輸至PID調(diào)節(jié)器，然后與用戶設(shè)定的壓力值進(jìn)行比較和運(yùn)算，并將比較和運(yùn)算的結(jié)果轉(zhuǎn)換為頻率調(diào)節(jié)信號和水泵啟動(dòng)臺(tái)數(shù)信號分別送至變頻器和可編程控制器（PLC）；變頻器據(jù)以調(diào)節(jié)水泵電機(jī)的電源頻率，進(jìn)而調(diào)整水泵的轉(zhuǎn)速；可編程控制器械根據(jù)PID調(diào)節(jié)器傳輸過來的水泵啟動(dòng)臺(tái)數(shù)信號控制水泵的運(yùn)轉(zhuǎn)。通過對水泵的啟動(dòng)和停止臺(tái)數(shù)及其中變頻泵轉(zhuǎn)速的調(diào)節(jié)，將用戶管網(wǎng)中的水壓恒移穩(wěn)于用戶預(yù)先設(shè)計(jì)的壓力值，使供水泵組“提升”的水量與用戶管網(wǎng)不斷變化的用水量保持一致，達(dá)到“變量恒壓供水”的目的。
以下為韓國SEOHO電氣株式會(huì)社研發(fā)的SOHO-SM矢量變頻器在某市市政供水工程中的應(yīng)用系統(tǒng)由可編程控制器，SOHO-SM變頻器和電動(dòng)機(jī)組成，采用可編程序控制器（PLC）控制變頻調(diào)速器，具有控制水泵恒壓供水的功能。通過安裝在管網(wǎng)上的壓力傳感器，把水壓轉(zhuǎn)換成4～20mA的模擬信號，通過PLC內(nèi)置的PID控制器，來改變電動(dòng)水泵轉(zhuǎn)速。當(dāng)用戶用水量增大，管網(wǎng)壓力低于設(shè)定壓力時(shí)，變頻調(diào)速的輸出頻率將增大，水泵轉(zhuǎn)速提高，供水量加大，當(dāng)達(dá)到設(shè)定壓力時(shí)，電動(dòng)水泵的轉(zhuǎn)速不在變化，使管網(wǎng)壓力恒定在設(shè)定壓力上；反之已然。這樣通過閉環(huán)PID控制就達(dá)到恒壓供水的目的。

當(dāng)電機(jī)出現(xiàn)故障（即：過壓、過流、過載、電機(jī)過熱保護(hù)）后，系統(tǒng)會(huì)自動(dòng)停止運(yùn)行，當(dāng)系統(tǒng)恢復(fù)后，再重新按操作步驟進(jìn)行操作。
二、SOHO-SM系列變頻器在紡織機(jī)械中的應(yīng)用
棉紡織設(shè)備的大部分機(jī)器采用了變頻調(diào)速技術(shù)、可編程控器(PLC)技術(shù)，也已有相當(dāng)一部分的產(chǎn)品采用了工控機(jī)、單片機(jī)、交流伺服系統(tǒng)、觸摸屏人機(jī)界面以及現(xiàn)場總線技術(shù)，實(shí)現(xiàn)了紡機(jī)產(chǎn)品的機(jī)電一體化，SOHO-SM變頻器在紡織設(shè)備上應(yīng)用很普及，從清花、梳棉、并條、粗紗、細(xì)紗、絡(luò)筒、整經(jīng)、漿紗、無梭織機(jī)等均已采用。按使用情況可分為三種類型：
第一類：一臺(tái)主機(jī)選用一臺(tái)SOHO-SM變頻器控制一臺(tái)電動(dòng)機(jī)，如并條機(jī)、粗紗機(jī)、細(xì)紗機(jī)等。
