1.儲(chu)水(shui)(shui)(shui)法(fa)充(chong)水(shui)(shui)(shui)用(yong)一個(ge)大木桶或水(shui)(shui)(shui)缸儲(chu)水(shui)(shui)(shui)，把(ba)它安(an)放在水(shui)(shui)(shui)泵(beng)附近，并使(shi)桶底(di)(di)稍高(gao)于水(shui)(shui)(shui)泵(beng)的出(chu)水(shui)(shui)(shui)口;或是(shi)在靠近泵(beng)房(fang)的一側修筑出(chu)水(shui)(shui)(shui)池(chi)時，將池(chi)底(di)(di)略降(jiang)低，形成一儲(chu)水(shui)(shui)(shui)池(chi)。用(yong)水(shui)(shui)(shui)管(guan)把(ba)桶(或池(chi))和(he)泵(beng)體充(chong)水(shui)(shui)(shui)孔連接起(qi)來(lai)。停機(ji)前，利用(yong)出(chu)水(shui)(shui)(shui)管(guan)流出(chu)的水(shui)(shui)(shui)把(ba)桶灌滿備(bei)用(yong)，下次起(qi)動時，便(bian)可自流充(chong)水(shui)(shui)(shui)。這種方法(fa)充(chong)水(shui)(shui)(shui)，使(shi)用(yong)簡便(bian)。　　
2.自吸(xi)離心(xin)泵(beng)這種(zhong)泵(beng)型(xing)(xing)是我(wo)國近(jin)(jin)幾年來，設計(ji)制造、推廣(guang)使(shi)用(yong)(yong)的一種(zhong)新(xin)型(xing)(xing)農(nong)用(yong)(yong)水泵(beng)。它不(bu)(bu)(bu)用(yong)(yong)底閥，起動前，向泵(beng)內灌(guan)入少量的水，起動時，就(jiu)能自動抽(chou)真空引水。停(ting)機后，下次再起動時，就(jiu)不(bu)(bu)(bu)需(xu)要再進行灌(guan)水。因此，使(shi)用(yong)(yong)很方(fang)便。我(wo)省近(jin)(jin)幾年來研制的SS型(xing)(xing)自吸(xi)式離心(xin)泵(beng)，規格(ge)有2、3、4寸，適合(he)于(yu)果園、農(nong)田(tian)灌(guan)溉(gai)之用(yong)(yong)。另外，為了發展噴灌(guan)技術，我(wo)國已聯合(he)設計(ji)并制出六種(zhong)規格(ge)的自吸(xi)噴灌(guan)泵(beng)系列產(chan)品。這種(zhong)泵(beng)型(xing)(xing)不(bu)(bu)(bu)僅用(yong)(yong)在農(nong)業上，還在建筑工地(di)上得到廣(guang)泛的應用(yong)(yong)。　
3.泵(beng)前水(shui)(shui)(shui)(shui)(shui)(shui)(shui)柜(ju)引水(shui)(shui)(shui)(shui)(shui)(shui)(shui)法在水(shui)(shui)(shui)(shui)(shui)(shui)(shui)泵(beng)前安裝一(yi)個圓筒(tong)形(xing)(xing)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)柜(ju)，柜(ju)頂為半球(qiu)形(xing)(xing)突(tu)起，柜(ju)內中部裝置一(yi)段吸(xi)(xi)(xi)上管(guan)，其(qi)管(guan)口(kou)低(di)于筒(tong)身高度，柜(ju)身下(xia)部出口(kou)與水(shui)(shui)(shui)(shui)(shui)(shui)(shui)泵(beng)吸(xi)(xi)(xi)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)管(guan)連接。水(shui)(shui)(shui)(shui)(shui)(shui)(shui)柜(ju)第一(yi)次使用前，從充(chong)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)口(kou)將水(shui)(shui)(shui)(shui)(shui)(shui)(shui)柜(ju)充(chong)滿水(shui)(shui)(shui)(shui)(shui)(shui)(shui)，然后封(feng)閉(bi)充(chong)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)口(kou)。啟動水(shui)(shui)(shui)(shui)(shui)(shui)(shui)泵(beng)運行(xing)，瞬間水(shui)(shui)(shui)(shui)(shui)(shui)(shui)泵(beng)將水(shui)(shui)(shui)(shui)(shui)(shui)(shui)柜(ju)內的(de)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)抽走，水(shui)(shui)(shui)(shui)(shui)(shui)(shui)位逐(zhu)漸下(xia)降(jiang)，容積逐(zhu)漸增(zeng)大(da)，形(xing)(xing)成真空狀態(tai)，產生吸(xi)(xi)(xi)力，從而把(ba)吸(xi)(xi)(xi)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)池的(de)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)吸(xi)(xi)(xi)到水(shui)(shui)(shui)(shui)(shui)(shui)(shui)柜(ju)中來，水(shui)(shui)(shui)(shui)(shui)(shui)(shui)泵(beng)繼(ji)續運行(xing)，水(shui)(shui)(shui)(shui)(shui)(shui)(shui)就源源不斷地被抽送(song)出去。　　　　
4.利用發動(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)排氣(qi)(qi)(qi)(qi)抽真(zhen)(zhen)空充水(shui)(shui)(shui)(shui)法把小型發動(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)的消(xiao)聲器卸下來，裝(zhuang)上特制的廢(fei)(fei)(fei)(fei)氣(qi)(qi)(qi)(qi)引(yin)(yin)水(shui)(shui)(shui)(shui)裝(zhuang)置(zhi)，利用發動(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)工作(zuo)過程(cheng)中排出的廢(fei)(fei)(fei)(fei)氣(qi)(qi)(qi)(qi)，抽走水(shui)(shui)(shui)(shui)泵(beng)(beng)(beng)中的空氣(qi)(qi)(qi)(qi)，使水(shui)(shui)(shui)(shui)泵(beng)(beng)(beng)產(chan)生(sheng)一定的真(zhen)(zhen)空度。操作(zuo)時(shi)，先(xian)起動(dong)(dong)(dong)(dong)發動(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)，然(ran)后把廢(fei)(fei)(fei)(fei)氣(qi)(qi)(qi)(qi)引(yin)(yin)水(shui)(shui)(shui)(shui)裝(zhuang)置(zhi)的手(shou)把向下壓緊，關(guan)(guan)閉(bi)廢(fei)(fei)(fei)(fei)氣(qi)(qi)(qi)(qi)排出口(kou)(kou)，從發動(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)排出的廢(fei)(fei)(fei)(fei)氣(qi)(qi)(qi)(qi)，經由廢(fei)(fei)(fei)(fei)氣(qi)(qi)(qi)(qi)噴射嘴排出，由于廢(fei)(fei)(fei)(fei)氣(qi)(qi)(qi)(qi)射流速(su)度大，壓力(li)低(di)，因而(er)產(chan)生(sheng)吸出作(zuo)用。當見到有連(lian)續不斷的氣(qi)(qi)(qi)(qi)水(shui)(shui)(shui)(shui)混(hun)合泡出現時(shi)，水(shui)(shui)(shui)(shui)泵(beng)(beng)(beng)就開始吸水(shui)(shui)(shui)(shui)。然(ran)后關(guan)(guan)閉(bi)泵(beng)(beng)(beng)體上的充水(shui)(shui)(shui)(shui)排氣(qi)(qi)(qi)(qi)孔，隨即提起手(shou)柄，打開廢(fei)(fei)(fei)(fei)氣(qi)(qi)(qi)(qi)排出口(kou)(kou)，水(shui)(shui)(shui)(shui)泵(beng)(beng)(beng)則轉(zhuan)入(ru)正(zheng)常工作(zuo)。這種充水(shui)(shui)(shui)(shui)方法，只適(shi)用于小型汽油(you)或柴油(you)發動(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)作(zuo)動(dong)(dong)(dong)(dong)力(li)的小口(kou)(kou)徑水(shui)(shui)(shui)(shui)泵(beng)(beng)(beng)。
