由于(yu)用(yong)途不同，要求各異，泵(beng)的形式(shi)也是多(duo)種(zhong)(zhong)多(duo)樣的。用(yong)于(yu)無塔(ta)供水器的泵(beng)，一般叫(jiao)深(shen)井泵(beng)，用(yong)于(yu)農(nong)業排灌的泵(beng)叫(jiao)農(nong)用(yong)排灌泵(beng)。按照不同的分類標準，農(nong)用(yong)水泵(beng)又有許多(duo)種(zhong)(zhong)形式(shi)。
一、按工作原理不(bu)同分類(lei)：
農用(yong)水(shui)泵(beng)(beng)(beng)(beng)(beng)按工作原(yuan)理(li)可分為葉(xie)(xie)(xie)片泵(beng)(beng)(beng)(beng)(beng)，如(ru)離心泵(beng)(beng)(beng)(beng)(beng)、軸(zhou)(zhou)流泵(beng)(beng)(beng)(beng)(beng)、混(hun)流泵(beng)(beng)(beng)(beng)(beng)等(deng)；容積(ji)泵(beng)(beng)(beng)(beng)(beng)，如(ru)柱(zhu)塞泵(beng)(beng)(beng)(beng)(beng)、隔膜泵(beng)(beng)(beng)(beng)(beng)、齒輪泵(beng)(beng)(beng)(beng)(beng)等(deng)；其他類型的(de)泵(beng)(beng)(beng)(beng)(beng)，如(ru)射(she)流泵(beng)(beng)(beng)(beng)(beng)、水(shui)錘泵(beng)(beng)(beng)(beng)(beng)等(deng)。無(wu)塔水(shui)泵(beng)(beng)(beng)(beng)(beng)中常見(jian)的(de)是葉(xie)(xie)(xie)片泵(beng)(beng)(beng)(beng)(beng)，可概括為離心泵(beng)(beng)(beng)(beng)(beng)、軸(zhou)(zhou)流泵(beng)(beng)(beng)(beng)(beng)和臟(zang)泵(beng)(beng)(beng)(beng)(beng)三大類。葉(xie)(xie)(xie)片泵(beng)(beng)(beng)(beng)(beng)的(de)共(gong)同特(te)點是都有(you)一個葉(xie)(xie)(xie)輪或(huo)數個葉(xie)(xie)(xie)輪，葉(xie)(xie)(xie)輪上裝有(you)數量(liang)不等(deng)的(de)葉(xie)(xie)(xie)片，葉(xie)(xie)(xie)片緊固在(zai)泵(beng)(beng)(beng)(beng)(beng)軸(zhou)(zhou)上，栗(li)軸(zhou)(zhou)用(yong)軸(zhou)(zhou)承支承與(yu)(yu)動力機(ji)(ji)軸(zhou)(zhou)相連接(jie)。在(zai)動力機(ji)(ji)的(de)帶動下，葉(xie)(xie)(xie)輪在(zai)旋轉過程中將(jiang)動力機(ji)(ji)的(de)機(ji)(ji)械(xie)能轉換為水(shui)能，通過與(yu)(yu)進(jin)、出(chu)水(shui)管連接(jie)的(de)泵(beng)(beng)(beng)(beng)(beng)殼將(jiang)水(shui)收集起來，并將(jiang)水(shui)的(de)部分動能轉換成(cheng)壓(ya)能，經出(chu)水(shui)管將(jiang)水(shui)從低處輸往高處。
二、按構造及使用要求分類
離(li)心泵(beng)(beng)(beng)、軸流(liu)泵(beng)(beng)(beng)和混流(liu)泵(beng)(beng)(beng)實際(ji)主(zhu)是(shi)根據液(ye)(ye)體從葉(xie)(xie)輪流(liu)毋的方向進行分類的。離(li)心泵(beng)(beng)(beng)是(shi)液(ye)(ye)體受(shou)離(li)心力(li)的作用(yong)，沿(yan)(yan)徑向流(liu)出葉(xie)(xie)輪的一種葉(xie)(xie)片(pian)泵(beng)(beng)(beng)，所(suo)以又叫徑流(liu)泵(beng)(beng)(beng)；軸流(liu)泵(beng)(beng)(beng)是(shi)根據液(ye)(ye)體在(zai)推力(li)的作用(yong)下，沿(yan)(yan)軸向流(liu)出葉(xie)(xie)輪的葉(xie)(xie)片(pian)泵(beng)(beng)(beng)，其原理類似飛機的螺(luo)旋槳(jiang)，故又稱為旋槳(jiang)泵(beng)(beng)(beng)；混流(liu)泵(beng)(beng)(beng)則是(shi)在(zai)離(li)心力(li)和推力(li)的雙重作用(yong)下，液(ye)(ye)體沿(yan)(yan)斜向流(liu)出葉(xie)(xie)輪的一種葉(xie)(xie)片(pian)泵(beng)(beng)(beng)，因此也(ye)有人稱做(zuo)對角線(xian)式(shi)泵(beng)(beng)(beng)。
離心泵(beng)(beng)按(an)其葉(xie)輪進(jin)水方式(shi)(shi)(shi)可分(fen)為單吸泵(beng)(beng)和雙吸泵(beng)(beng)，按(an)葉(xie)輪的數目可分(fen)為單級泵(beng)(beng)（一臺泵(beng)(beng)出只有一個葉(xie)輪）和多級泵(beng)(beng)(將兩個或(huo)兩個以上的葉(xie)輪裝(zhuang)在(zai)同(tong)一根軸(zhou)(zhou)上串(chuan)聯工(gong)作(zuo)，一臺泵(beng)(beng)上裝(zhuang)幾(ji)個葉(xie)輪就叫(jiao)幾(ji)級泵(beng)(beng))，按(an)泵(beng)(beng)軸(zhou)(zhou)的方向(xiang)(xiang)分(fen)為立式(shi)(shi)(shi)和臥式(shi)(shi)(shi)。軸(zhou)(zhou)流泵(beng)(beng)按(an)其泵(beng)(beng)軸(zhou)(zhou)的方向(xiang)(xiang)可分(fen)為立式(shi)(shi)(shi)、臥式(shi)(shi)(shi)和斜式(shi)(shi)(shi)，按(an)葉(xie)片(pian)安裝(zhuang)角是(shi)否可調分(fen)為固(gu)定葉(xie)片(pian)式(shi)(shi)(shi)、半調節式(shi)(shi)(shi)。混流泵(beng)(beng)按(an)泵(beng)(beng)蚰的方向(xiang)(xiang)也(ye)可分(fen)為立式(shi)(shi)(shi)和臥式(shi)(shi)(shi)，按(an)泵(beng)(beng)體的結構可分(fen)為蝸殼式(shi)(shi)(shi)和導葉(xie)式(shi)(shi)(shi)。
根(gen)據(ju)構造和(he)使用的(de)要求，葉片(pian)泵(beng)(beng)(beng)(beng)(beng)(beng)中(zhong)還有(you)長軸井(jing)(jing)泵(beng)(beng)(beng)(beng)(beng)(beng)、潛(qian)水(shui)(shui)(shui)(shui)(shui)(shui)電(dian)泵(beng)(beng)(beng)(beng)(beng)(beng)、自(zi)(zi)吸泵(beng)(beng)(beng)(beng)(beng)(beng)、水(shui)(shui)(shui)(shui)(shui)(shui)輪(lun)泵(beng)(beng)(beng)(beng)(beng)(beng)等。長軸井(jing)(jing)泵(beng)(beng)(beng)(beng)(beng)(beng)有(you)一(yi)個長的(de)傳動軸，根(gen)據(ju)井(jing)(jing)的(de)結構和(he)揚程的(de)高低(di)，又(you)甩分為淺井(jing)(jing)泵(beng)(beng)(beng)(beng)(beng)(beng)和(he)深井(jing)(jing)泵(beng)(beng)(beng)(beng)(beng)(beng)。落水(shui)(shui)(shui)(shui)(shui)(shui)電(dian)泵(beng)(beng)(beng)(beng)(beng)(beng)是馬電(dian)動機(ji)聯(lian)成(cheng)一(yi)體、潛(qian)人水(shui)(shui)(shui)(shui)(shui)(shui)中(zhong)抽水(shui)(shui)(shui)(shui)(shui)(shui)的(de)泵(beng)(beng)(beng)(beng)(beng)(beng)。用來從深井(jing)(jing)中(zhong)抽水(shui)(shui)(shui)(shui)(shui)(shui)的(de)潛(qian)水(shui)(shui)(shui)(shui)(shui)(shui)電(dian)泵(beng)(beng)(beng)(beng)(beng)(beng)叫深井(jing)(jing)潛(qian)水(shui)(shui)(shui)(shui)(shui)(shui)電(dian)泵(beng)(beng)(beng)(beng)(beng)(beng)。自(zi)(zi)吸泵(beng)(beng)(beng)(beng)(beng)(beng)是在泵(beng)(beng)(beng)(beng)(beng)(beng)體內儲(chu)有(you)部分水(shui)(shui)(shui)(shui)(shui)(shui)體，能自(zi)(zi)行排氣充水(shui)(shui)(shui)(shui)(shui)(shui)的(de)離心泵(beng)(beng)(beng)(beng)(beng)(beng)。水(shui)(shui)(shui)(shui)(shui)(shui)輪(lun)泵(beng)(beng)(beng)(beng)(beng)(beng)是用水(shui)(shui)(shui)(shui)(shui)(shui)流(liu)驅動水(shui)(shui)(shui)(shui)(shui)(shui)輪(lun)機(ji)帶動同(tong)軸的(de)水(shui)(shui)(shui)(shui)(shui)(shui)泵(beng)(beng)(beng)(beng)(beng)(beng)抽水(shui)(shui)(shui)(shui)(shui)(shui)的(de)一(yi)種(zhong)葉片(pian)泵(beng)(beng)(beng)(beng)(beng)(beng)。
