（4）無(wu)密(mi)封自(zi)控自(zi)吸(xi)泵(beng)的吸水管末端安裝吸水底閥。吸水底閥事實上是一種止回閥，吸水底閥可以確保水流只能從水池進入吸水管而不可以倒流，假如吸水管中充滿水，自吸泵軸線標高與水池的工作水位，但是由于有吸水底閥的作用，吸水管中的水不會流到水池，能使吸水管中一直都有水充滿，確保高吸程自吸泵能自動并且快速的啟動。

大流量自吸(xi)泵(beng)我們建議(yi)先把(ba)泵(beng)體(ti)中加(jia)水加(jia)到可以(yi)從進水口向(xiang)水池倒流為止，接著送電(dian)啟動(dong)自吸(xi)泵(beng)與真空(kong)泵(beng)一同啟動(dong)，由于自吸(xi)泵(beng)本身也(ye)會有自吸(xi)能力(li)，兩(liang)臺泵(beng)一起運行在自吸(xi)高度(du)超出8米(mi)的(de)(de)(de)工況自吸(xi)性(xing)能(neng)會有比較(jiao)明顯的(de)(de)(de)改變，在(zai)防汛車上(shang)使(shi)用(yong)的(de)(de)(de)應該配(pei)置(zhi)一(yi)個1寸小潛水泵(beng)(beng)來作(zuo)為一(yi)次使(shi)用(yong)驗收，前提是先把里面(mian)加好(hao)水，這樣自吸(xi)泵(beng)(beng)與真空泵(beng)(beng)同時(shi)會發揮出它們的(de)(de)(de)自吸(xi)性(xing)能(neng)，上(shang)水的(de)(de)(de)時(shi)間也會大(da)大(da)地縮短(duan)，將螺絲松掉后將蓋(gai)板打開就(jiu)能(neng)為自吸(xi)泵(beng)(beng)加水，加好(hao)水后將螺絲擰(ning)緊就(jiu)能(neng)實現兩臺泵(beng)(beng)同時(shi)運(yun)行。
