真(zhen)空(kong)(kong)引水(shui)(shui)系(xi)統(tong)是(shi)無底閥液上安裝的泵(beng)(beng)(beng)(beng)，利用真(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)輔助引水(shui)(shui)的系(xi)統(tong)。真(zhen)空(kong)(kong)引水(shui)(shui)系(xi)統(tong)分兩部(bu)分：一(yi)部(bu)分是(shi)供水(shui)(shui)泵(beng)(beng)(beng)(beng)及(ji)管(guan)路(lu)；一(yi)部(bu)分是(shi)真(zhen)空(kong)(kong)泵(beng)(beng)(beng)(beng)及(ji)輔助管(guan)路(lu)。真(zhen)空(kong)(kong)系(xi)統(tong)可(ke)實現真(zhen)空(kong)(kong)抽吸和(he)真(zhen)空(kong)(kong)保持功能，解決(jue)水(shui)(shui)泵(beng)(beng)(beng)(beng)啟動前的排氣引水(shui)(shui)工(gong)作程序，實現了供水(shui)(shui)泵(beng)(beng)(beng)(beng)方便、隨(sui)時、快速地啟動。

真空系統可實現(xian)真空抽吸和真空保(bao)持(chi)功能，解決水(shui)泵(beng)(beng)(beng)啟(qi)動(dong)前(qian)的(de)氣(qi)引水(shui)工(gong)作程序，實現(xian)了供水(shui)泵(beng)(beng)(beng)方(fang)便、隨時、快速地啟(qi)動(dong)。并在水(shui)泵(beng)(beng)(beng)運行中隨時抽吸泵(beng)(beng)(beng)內和吸水(shui)管內逸(yi)出空氣(qi)的(de)雙重功能，可防止汽蝕的(de)發生。
水(shui)泵關鍵部(bu)件材(cai)質正確(que)的(de)選擇，有(you)(you)效的(de)延(yan)長了水(shui)泵的(de)使用壽命，降(jiang)低故障率，降(jiang)低維修及備(bei)件費用。潔(jie)凈機封水(shui)的(de)引入(ru)，解決了真空泄露問題，又有(you)(you)效地延(yan)長了機械密封的(de)壽命。供水(shui)泵的(de)維修周期在2年以上(shang)。
真空引(yin)水系(xi)統(tong)操作方便快捷(jie)，故障率低，維修方便，與(yu)無密封自(zi)控自(zi)吸泵相比，節能顯著，真空引(yin)水系(xi)統(tong)在旋流井中(zhong)成功的應用(yong)，為旋流井中(zhong)泵型的選(xuan)擇提供了一個(ge)新方向(xiang)
