一、真空排水系統說明
1、真空引水裝置的組(zu)成
真空泵2臺(1用1備,也可以同時啟動),氣水分離器1個、液位自動控制系統1套、PLC電控箱1個、前置分離器1個(主要是用于防止水進入真空泵內)及深圳恒才真空泵廠家配套的相應閥門、管件等,如詳情圖所示,真空排水系統_引水真空機組_負壓引水機組。
2、真空引水裝置原理
(1)真空泵主機(ji),兩(liang)臺(tai)(一備(bei)一用),電機(ji):寬頻50HZ/60HZ通用,寬電壓(ya)200-480V。;
(2)真(zhen)空(kong)(kong)(kong)引水(shui)時(shi),真(zhen)空(kong)(kong)(kong)泵啟動,管路頂部的(de)空(kong)(kong)(kong)腔形成(cheng)真(zhen)空(kong)(kong)(kong),水(shui)被吸入空(kong)(kong)(kong)腔內(nei),空(kong)(kong)(kong)腔上(shang)部安裝有(you)液位(wei)自(zi)動控(kong)制系(xi)統(tong)(tong)(tong),當(dang)其感(gan)應(ying)到液位(wei)時(shi),水(shui)已(yi)經充滿空(kong)(kong)(kong)腔,液位(wei)自(zi)動控(kong)制系(xi)統(tong)(tong)(tong)發信號(hao)給集(ji)(ji)控(kong)系(xi)統(tong)(tong)(tong),集(ji)(ji)控(kong)系(xi)統(tong)(tong)(tong)啟動主水(shui)泵,開始引水(shui),水(shui)泵引水(shui)時(shi),真(zhen)空(kong)(kong)(kong)泵停止運行,處于(yu)待機(ji)狀態(tai);
(3)空腔抽真(zhen)空過程中可(ke)(ke)能會有(you)少量的(de)水(shui)被帶出,為(wei)防止進入到(dao)真(zhen)空泵里,在真(zhen)空泵前(qian)加裝前(qian)置(zhi)分離器(qi),并配有(you)高液位(wei)開關,可(ke)(ke)檢測高液位(wei),高液位(wei)報(bao)警(jing);
(4)真空(kong)泵停(ting)止運行,程序設定前置分離器(qi)排(pai)水,即打(da)開排(pai)水電(dian)動閥,同時(shi)打(da)開破(po)真空(kong)電(dian)動閥,進(jin)行排(pai)水,排(pai)水時(shi)間設定的較長,保證前置分離器(qi)的水完(wan)全排(pai)掉;
(5)汽水分離器配(pei)有低液(ye)位開關,檢測其液(ye)位過低并報(bao)警;
(6)就地(di)PLC控制箱(xiang)有遠程/本(ben)地(di)/停止選擇按鈕,當選擇遠程時具有鎖定(ding)功(gong)能;
(7)提供兩臺泵(beng)的運行點(dian)、故障點(dian)、遠程點(dian)、啟停點(dian)、手(shou)自(zi)動啟停點(dian)等給(gei)集控(kong)系統;
(8)提(ti)供前置(zhi)分離器高液位信號給(gei)集控(kong)系統(tong),并報警;
(9)提供汽水(shui)分離器低(di)液位信號(hao)(缺水(shui))給集控系統(tong),并報警;
(10)可提供MODBUS、RS485通訊協議。真空排水系統_引水真空機組_負壓引水機組
