若自來水供水因故壓力不足或短時缺水時，可能影響產(chǎn)品質(zhì)量，嚴重時使產(chǎn)品報廢和設(shè)備損壞。又如當發(fā)生火警時，若供水壓力不足或無水供應(yīng)，不能迅速滅火，可能引起重大經(jīng)濟損失和人員傷亡。所以某些用水區(qū)采用恒壓供水系統(tǒng)，具有較大的經(jīng)濟和社會意義。
在舊加壓設(shè)備中，恒壓供水一般采用起動或停止加壓站的水泵和調(diào)節(jié)出口閥開度來實現(xiàn)。控制系統(tǒng)是采用繼電接觸器控制線路，這種系統(tǒng)線路復(fù)雜，維護困難，操作麻煩，工人要24小時值班看守，勞動強度大。所以有必要對之進行改造，提高自動化水平。
本文介紹的用于某自來水加壓站快速起動恒壓供水監(jiān)控系統(tǒng)，采用松下電工生產(chǎn)的FP3型可編程序控制器（PLC）進行控制，用研華工控機進行監(jiān)控，自動化程度高，整個工作程序自動完成，能清楚地顯示各個設(shè)備的實時狀態(tài)，并自動調(diào)節(jié)水壓
