清水(shui)泵(beng)是供輸送(song)清水(shui)及(ji)物理(li)化學性質類(lei)似(si)于清水(shui)的(de)其他(ta)液體之用，適用于工(gong)業和(he)城市給排(pai)水(shui)、高層建(jian)筑增壓送(song)水(shui)、園(yuan)林噴灌、消防增壓、遠(yuan)距離輸送(song)、暖通制(zhi)冷循環、農田灌溉、浴(yu)室等冷暖水(shui)循環增壓及(ji)設備配套。

清(qing)(qing)水(shui)(shui)(shui)(shui)泵(beng)分立式清(qing)(qing)水(shui)(shui)(shui)(shui)泵(beng)、臥式清(qing)(qing)水(shui)(shui)(shui)(shui)泵(beng)、單級(ji)清(qing)(qing)水(shui)(shui)(shui)(shui)泵(beng)、多級(ji)清(qing)(qing)水(shui)(shui)(shui)(shui)泵(beng)、離(li)心(xin)式清(qing)(qing)水(shui)(shui)(shui)(shui)泵(beng)、自吸式清(qing)(qing)水(shui)(shui)(shui)(shui)泵(beng)。

果園單相清水(shui)泵(beng)分為(wei)自(zi)吸式水(shui)泵(beng)、充水(shui)式水(shui)泵(beng)和潛(qian)水(shui)式水(shui)泵(beng)，選擇原則是(shi)：

1、自吸(xi)(xi)式(shi)清水(shui)(shui)泵(beng)(beng)：水(shui)(shui)源質量好相對固定(ding)(ding)工作位置，吸(xi)(xi)程(cheng)在3.5米以內管道穩定(ding)(ding)，用(yong)在水(shui)(shui)井(jing)生活供水(shui)(shui)、果(guo)園灌溉時可減(jian)少(shao)泵(beng)(beng)水(shui)(shui)時充水(shui)(shui)麻(ma)煩(fan)，實際揚程(cheng)在22米以下，工作效率稍(shao)差(cha)化工泵(beng)(beng)。一次(ci)投入(ru)(ru)運(yun)行時應先加入(ru)(ru)循環排空用(yong)水(shui)(shui)，水(shui)(shui)泵(beng)(beng)才(cai)能完成自吸(xi)(xi)。

2、充水(shui)式(shi)清水(shui)泵：水(shui)源(yuan)水(shui)質好移(yi)動性大管道相對(dui)不固(gu)定(ding)，吸程2.5米內實際揚(yang)程在32米內，水(shui)泵流量可根(gen)據需(xu)要(yao)而(er)任(ren)意調(diao)節，適應種果專業戶作(zuo)噴灑農(nong)藥、灌溉供水(shui)，工作(zuo)效率較高。吸水(shui)管應保(bao)證密封良好。

3、潛(qian)水(shui)(shui)式(shi)清水(shui)(shui)泵(beng)(beng)(beng)(beng)：水(shui)(shui)源充足揚程(cheng)低，閥門(men)(men)(men)適用于農田果園水(shui)(shui)量大的灌溉。因潛(qian)水(shui)(shui)泵(beng)(beng)(beng)(beng)整機放入(ru)水(shui)(shui)中(zhong)工(gong)作軸(zhou)向(xiang)推水(shui)(shui)上(shang)升，減少出水(shui)(shui)量將加大水(shui)(shui)泵(beng)(beng)(beng)(beng)負荷。所以在潛(qian)水(shui)(shui)泵(beng)(beng)(beng)(beng)出水(shui)(shui)管中(zhong)不要裝閥門(men)(men)(men)，防止因閥門(men)(men)(men)關閉開機水(shui)(shui)泵(beng)(beng)(beng)(beng)阻(zu)力過大燒壞(huai)電機。
