清(qing)水(shui)(shui)泵(beng)是(shi)供輸(shu)送清(qing)水(shui)(shui)及(ji)物理化學性(xing)質(zhi)類似于清(qing)水(shui)(shui)的其他液體之用(yong)，適(shi)用(yong)于工業和城市給(gei)排(pai)水(shui)(shui)、高(gao)層建(jian)筑增壓送水(shui)(shui)、園林噴灌、消(xiao)防增壓、遠(yuan)距離輸(shu)送、暖通制冷循環、農田灌溉、浴室等冷暖水(shui)(shui)循環增壓及(ji)設備配套。

清(qing)水(shui)(shui)泵(beng)(beng)分立(li)式(shi)(shi)清(qing)水(shui)(shui)泵(beng)(beng)、臥式(shi)(shi)清(qing)水(shui)(shui)泵(beng)(beng)、單級清(qing)水(shui)(shui)泵(beng)(beng)、多級清(qing)水(shui)(shui)泵(beng)(beng)、離心(xin)式(shi)(shi)清(qing)水(shui)(shui)泵(beng)(beng)、自(zi)吸(xi)式(shi)(shi)清(qing)水(shui)(shui)泵(beng)(beng)。

果園單相清水(shui)泵(beng)分為(wei)自吸式水(shui)泵(beng)、充水(shui)式水(shui)泵(beng)和潛水(shui)式水(shui)泵(beng)，選擇原(yuan)則是：

1、自吸式(shi)清水(shui)(shui)(shui)泵：水(shui)(shui)(shui)源質量(liang)好相對(dui)固定工(gong)作位(wei)置，吸程(cheng)在(zai)(zai)3.5米以(yi)內管道(dao)穩定，用在(zai)(zai)水(shui)(shui)(shui)井生活供水(shui)(shui)(shui)、果園(yuan)灌溉時可減少泵水(shui)(shui)(shui)時充水(shui)(shui)(shui)麻煩，實際揚程(cheng)在(zai)(zai)22米以(yi)下，工(gong)作效率(lv)稍差化工(gong)泵。一次投入運行(xing)時應先加入循環排空用水(shui)(shui)(shui)，水(shui)(shui)(shui)泵才能完成自吸。

2、充水(shui)(shui)式清(qing)水(shui)(shui)泵：水(shui)(shui)源水(shui)(shui)質好移(yi)動(dong)性大管(guan)道相對不固定，吸(xi)程2.5米(mi)內實際揚程在32米(mi)內，水(shui)(shui)泵流量可根據需要而任意(yi)調節，適應種(zhong)果專業(ye)戶作噴灑(sa)農藥、灌(guan)溉供水(shui)(shui)，工作效率(lv)較高(gao)。吸(xi)水(shui)(shui)管(guan)應保證密封良好。

3、潛(qian)水(shui)(shui)式(shi)清水(shui)(shui)泵(beng)：水(shui)(shui)源充足揚程低，閥門(men)(men)適用于(yu)農田果園水(shui)(shui)量大的灌溉。因(yin)潛(qian)水(shui)(shui)泵(beng)整機放入水(shui)(shui)中(zhong)工作(zuo)軸向推水(shui)(shui)上升，減少出水(shui)(shui)量將(jiang)加(jia)大水(shui)(shui)泵(beng)負荷。所以在潛(qian)水(shui)(shui)泵(beng)出水(shui)(shui)管中(zhong)不要裝閥門(men)(men)，防(fang)止因(yin)閥門(men)(men)關閉開機水(shui)(shui)泵(beng)阻力過大燒壞電機。
