真空引水系統是無底閥液上安裝的泵，采用真空泵輔助引水的系統。本實用新型分為兩個部分：一部分為供水泵和管道，一部分為真空泵和輔管。真空系統可實現真空抽吸和真空保持功能，解決水泵啟動前的排氣引水工作程序，實(真空引水器)現了供水泵方便、隨時、快速地啟動。
給水(shui)(shui)(shui)泵(beng)及輔助(zhu)管路由進水(shui)(shui)(shui)管、給水(shui)(shui)(shui)泵(beng)、出水(shui)(shui)(shui)管、機封(feng)沖洗水(shui)(shui)(shui)管組成(cheng)。泵(beng)工作時，水(shui)(shui)(shui)通過(guo)進水(shui)(shui)(shui)管通過(guo)出水(shui)(shui)(shui)管輸送給用戶。
真(zhen)(zhen)空(kong)(kong)泵(beng)(beng)(真(zhen)(zhen)空(kong)(kong)引水(shui)(shui)(shui)(shui)器)及輔助管(guan)(guan)(guan)路由真(zhen)(zhen)空(kong)(kong)罐(guan)、真(zhen)(zhen)空(kong)(kong)泵(beng)(beng)、氣(qi)水(shui)(shui)(shui)(shui)分(fen)離器、水(shui)(shui)(shui)(shui)箱、水(shui)(shui)(shui)(shui)箱補(bu)水(shui)(shui)(shui)(shui)管(guan)(guan)(guan)路、控(kong)制柜、聯接管(guan)(guan)(guan)路與儀表閥(fa)門組(zu)成(cheng)。進料泵(beng)(beng)在起動(dong)前，進水(shui)(shui)(shui)(shui)管(guan)(guan)(guan)、給(gei)水(shui)(shui)(shui)(shui)泵(beng)(beng)、出(chu)水(shui)(shui)(shui)(shui)管(guan)(guan)(guan)內的氣(qi)體經水(shui)(shui)(shui)(shui)泵(beng)(beng)排(pai)出(chu)，首先進入(ru)真(zhen)(zhen)空(kong)(kong)罐(guan)(抽水(shui)(shui)(shui)(shui)至(zhi)一(yi)定程(cheng)度(du)，將水(shui)(shui)(shui)(shui)留在真(zhen)(zhen)空(kong)(kong)罐(guan)中)，再進入(ru)真(zhen)(zhen)空(kong)(kong)泵(beng)(beng)的作用(yong)下(xia)進入(ru)氣(qi)水(shui)(shui)(shui)(shui)分(fen)離器，*后(hou)排(pai)入(ru)大氣(qi)。真(zhen)(zhen)空(kong)(kong)罐(guan)底有聯接管(guan)(guan)(guan)與進水(shui)(shui)(shui)(shui)管(guan)(guan)(guan)相連，構成(cheng)平衡管(guan)(guan)(guan)路，保持真(zhen)(zhen)空(kong)(kong)罐(guan)中的真(zhen)(zhen)空(kong)(kong)度(du)。完成(cheng)引水(shui)(shui)(shui)(shui)后(hou)，給(gei)水(shui)(shui)(shui)(shui)泵(beng)(beng)可(ke)以隨時啟(qi)(qi)動(dong)，在運(yun)行(xing)過程(cheng)中，真(zhen)(zhen)空(kong)(kong)度(du)低(di)于*低(di)值(zhi)時，真(zhen)(zhen)空(kong)(kong)泵(beng)(beng)啟(qi)(qi)動(dong)，將系統的真(zhen)(zhen)空(kong)(kong)度(du)抽至(zhi)*高值(zhi)后(hou)真(zhen)(zhen)空(kong)(kong)泵(beng)(beng)停止。真(zhen)(zhen)空(kong)(kong)度(du)的*低(di)值(zhi)要保證給(gei)水(shui)(shui)(shui)(shui)泵(beng)(beng)在任意(yi)時刻啟(qi)(qi)動(dong)上水(shui)(shui)(shui)(shui)。
