潜水(shui)(shui)(shui)电泵(beng)是深(shen)井提(ti)水(shui)(shui)(shui)的(de)重(zhong)要设备(bei)。使(shi)(shi)用(yong)时整个(ge)机组(zu)潜入(ru)水(shui)(shui)(shui)中工(gong)作(zuo)。把地下(xia)水(shui)(shui)(shui)提(ti)取到(dao)地表，是生(sheng)活用(yong)水(shui)(shui)(shui)、矿山(shan)抢险、工(gong)业冷却、农(nong)田灌溉、海(hai)水(shui)(shui)(shui)提(ti)升、轮船调(diao)载，还可用(yong)于(yu)喷泉景观，热水(shui)(shui)(shui)潜水(shui)(shui)(shui)泵(beng)用(yong)于(yu)温泉洗浴(yu)，还可适用(yong)于(yu)从深(shen)井中提(ti)取地下(xia)水(shui)(shui)(shui)，也可用(yong)于(yu)河流、水(shui)(shui)(shui)库、水(shui)(shui)(shui)渠等提(ti)水(shui)(shui)(shui)工(gong)程。主要用(yong)于(yu)农(nong)田灌溉及高山(shan)区人(ren)畜(chu)用(yong)水(shui)(shui)(shui)，亦(yi)可供中央空调(diao)冷却、热泵(beng)机组(zu)、冷泵(beng)机组(zu)、城市、工(gong)厂(chang)、铁路、矿山(shan)、工(gong)地排水(shui)(shui)(shui)使(shi)(shi)用(yong)。一般流量可以达到(dao)(10立方(fang)米~650立方(fang)米)每小时、扬程可达到(dao)1500米。那么，潜水(shui)(shui)(shui)电泵(beng)使(shi)(shi)用(yong)中有哪些注(zhu)意事项(xiang)？

1、不能接地

潜(qian)水(shui)(shui)(shui)电(dian)(dian)泵(beng)采(cai)取保(bao)护(hu)接(jie)(jie)地(di)(di)(di)(di)是国家强制(zhi)性(xing)标准(zhun)的(de)要求(qiu)。只有采(cai)取保(bao)护(hu)接(jie)(jie)地(di)(di)(di)(di)，才能确保(bao)使用时(shi)的(de)人身安全(quan)。如果没有保(bao)护(hu)接(jie)(jie)地(di)(di)(di)(di)，一旦外壳(qiao)(qiao)(qiao)漏(lou)电(dian)(dian)，就造成(cheng)潜(qian)水(shui)(shui)(shui)泵(beng)出(chu)水(shui)(shui)(shui)口处(chu)的(de)水(shui)(shui)(shui)及抽水(shui)(shui)(shui)的(de)水(shui)(shui)(shui)面(mian)带电(dian)(dian)，危及人畜(chu)安全(quan)，同时(shi)浪费(fei)大(da)量电(dian)(dian)能。若将潜(qian)水(shui)(shui)(shui)泵(beng)的(de)金属外壳(qiao)(qiao)(qiao)与符(fu)合国家标准(zhun)的(de)接(jie)(jie)地(di)(di)(di)(di)体(接(jie)(jie)地(di)(di)(di)(di)电(dian)(dian)阻不大(da)于4Ω)接(jie)(jie)地(di)(di)(di)(di)连接(jie)(jie)，当(dang)潜(qian)水(shui)(shui)(shui)泵(beng)外壳(qiao)(qiao)(qiao)漏(lou)电(dian)(dian)时(shi)，电(dian)(dian)流经潜(qian)水(shui)(shui)(shui)泵(beng)金属外壳(qiao)(qiao)(qiao)、保(bao)护(hu)接(jie)(jie)地(di)(di)(di)(di)线、接(jie)(jie)地(di)(di)(di)(di)体、大(da)地(di)(di)(di)(di)、变压器的(de)工作接(jie)(jie)地(di)(di)(di)(di)线和电(dian)(dian)源(yuan)形成(cheng)一个闭合回路，当(dang)漏(lou)电(dian)(dian)流过大(da)时(shi)，特(te)别是火(huo)线碰(peng)壳(qiao)(qiao)(qiao)时(shi)，就能使潜(qian)水(shui)(shui)(shui)泵(beng)的(de)保(bao)护(hu)装置动作(熔断器熔断或(huo)空气开关跳闸)，切(qie)断漏(lou)电(dian)(dian)潜(qian)水(shui)(shui)(shui)泵(beng)的(de)电(dian)(dian)源(yuan)。

2、不安装漏电保(bao)护器

潜(qian)(qian)水电(dian)(dian)(dian)(dian)泵(beng)工作(zuo)在水中(zhong)，容易漏(lou)(lou)(lou)电(dian)(dian)(dian)(dian)造成(cheng)电(dian)(dian)(dian)(dian)能损失甚(shen)至引(yin)发触电(dian)(dian)(dian)(dian)事故。如果(guo)装有(you)漏(lou)(lou)(lou)电(dian)(dian)(dian)(dian)保(bao)护(hu)器，只要潜(qian)(qian)水泵(beng)漏(lou)(lou)(lou)电(dian)(dian)(dian)(dian)值超过漏(lou)(lou)(lou)电(dian)(dian)(dian)(dian)保(bao)护(hu)器的动作(zuo)电(dian)(dian)(dian)(dian)流值(一般不超过30mA)，漏(lou)(lou)(lou)电(dian)(dian)(dian)(dian)保(bao)护(hu)器就会切断潜(qian)(qian)水电(dian)(dian)(dian)(dian)泵(beng)的电(dian)(dian)(dian)(dian)源。

3、电(dian)源电(dian)压异常时(shi)开机

电(dian)压(ya)(ya)(ya)过(guo)高(gao)(gao)和过(guo)低(di)都会使潜水(shui)(shui)泵温(wen)升过(guo)高(gao)(gao)，缩短使用(yong)寿(shou)命甚至烧毁潜水(shui)(shui)泵。农村由于(yu)低(di)压(ya)(ya)(ya)供电(dian)线路(lu)比较(jiao)长，线路(lu)末端(duan)电(dian)压(ya)(ya)(ya)过(guo)低(di)、始端(duan)电(dian)压(ya)(ya)(ya)过(guo)高(gao)(gao)是常(chang)有的(de)事。因(yin)此，在(zai)使用(yong)潜水(shui)(shui)泵的(de)过(guo)程中，操作者必须随时(shi)观(guan)察电(dian)源电(dian)压(ya)(ya)(ya)值，若(ruo)低(di)于(yu)额定(ding)电(dian)压(ya)(ya)(ya)10%以(yi)下(xia)，高(gao)(gao)于(yu)额定(ding)电(dian)压(ya)(ya)(ya)10%以(yi)上，或电(dian)流大(da)于(yu)潜水(shui)(shui)泵额定(ding)电(dian)流的(de)20%时(shi)，应立(li)即(ji)停(ting)机，并(bing)避免电(dian)源电(dian)压(ya)(ya)(ya)异常(chang)时(shi)开机。

4、电机反方向旋转

现在有许多(duo)类型的(de)潜水(shui)泵(beng)(beng)正(zheng)转(zhuan)(zhuan)和反(fan)转(zhuan)(zhuan)皆可(ke)出水(shui)，但反(fan)转(zhuan)(zhuan)时出水(shui)量小、电流大(da)，反(fan)转(zhuan)(zhuan)时间长(zhang)了会损坏电机(ji)绕组。因此，潜水(shui)电泵(beng)(beng)入水(shui)前应(ying)先(xian)接电源检查旋(xuan)转(zhuan)(zhuan)方向是否正(zheng)确。若三(san)(san)相(xiang)潜水(shui)泵(beng)(beng)叶轮(lun)倒(dao)转(zhuan)(zhuan)，应(ying)立即(ji)停(ting)机(ji)，调(diao)换电缆中(zhong)(zhong)三(san)(san)相(xiang)芯线中(zhong)(zhong)任(ren)意(yi)两相(xiang)的(de)接线即(ji)可(ke)。

5、长期超负荷工作

为避免潜(qian)水(shui)电泵(beng)(beng)(beng)长(zhang)期超负荷(he)工作，不要(yao)把(ba)低扬程泵(beng)(beng)(beng)用于(yu)高(gao)扬程工作，不要(yao)抽含沙量大(重(zhong)泥浆)的水(shui)，并随时(shi)观(guan)察(cha)电流值(zhi)是否(fou)在规定的范围(wei)内。若发现电流过大，应停机检(jian)查(cha)。另(ling)外(wai)，潜(qian)水(shui)泵(beng)(beng)(beng)以水(shui)为冷(leng)却源，因此，潜(qian)水(shui)泵(beng)(beng)(beng)脱水(shui)运行的时(shi)间不宜(yi)过长(zhang)。

6、频繁开关

潜(qian)水电(dian)泵不宜过于(yu)频繁启(qi)(qi)动，这(zhei)是(shi)因为潜(qian)水泵停(ting)转(zhuan)时会产生回流，若(ruo)立即开机(ji)，会使电(dian)机(ji)负载启(qi)(qi)动，导致启(qi)(qi)动电(dian)流过大。因此，停(ting)机(ji)后要(yao)等管内(nei)的存水回流完毕才(cai)能再(zai)次启(qi)(qi)动，一般需要(yao)间隔5min左右。

7、在(zai)淤泥环境中使(shi)用

潜(qian)(qian)水(shui)(shui)(shui)电(dian)泵在使(shi)用(yong)时如(ru)果沉(chen)(chen)入(ru)泥中(zhong)，会导致(zhi)散热(re)不良而烧坏电(dian)机绕组。因(yin)此，潜(qian)(qian)水(shui)(shui)(shui)泵一定(ding)不能在淤(yu)(yu)泥环(huan)境(jing)中(zhong)使(shi)用(yong)。为防止潜(qian)(qian)水(shui)(shui)(shui)泵沉(chen)(chen)入(ru)淤(yu)(yu)泥中(zhong)，应在潜(qian)(qian)水(shui)(shui)(shui)泵下水(shui)(shui)(shui)前清除其工作(zuo)环(huan)境(jing)内淤(yu)(yu)泥，有条件时还应采(cai)用(yong)栅栏(lan)护罩(zhao)把潜(qian)(qian)水(shui)(shui)(shui)泵罩(zhao)住，以(yi)避免废弃(qi)物堵住进水(shui)(shui)(shui)栅栏(lan)，导致(zhi)电(dian)机发热(re)、出水(shui)(shui)(shui)不畅。

8、停(ting)用后(hou)长期放(fang)在水中不管不问

潜水(shui)电泵(beng)如果下(xia)井后不(bu)连续使(shi)用，时(shi)间(jian)长了(le)会(hui)锈(xiu)蚀(shi)，导致不(bu)能启动。因此，停用的(de)潜水(shui)泵(beng)切忌放(fang)在(zai)(zai)水(shui)中(zhong)(zhong)不(bu)管(guan)不(bu)问，应每(mei)周开机一(yi)次，运行(xing)5～10min。长期不(bu)用时(shi)，Z好不(bu)长时(shi)间(jian)浸泡在(zai)(zai)水(shui)中(zhong)(zhong)，应放(fang)在(zai)(zai)清水(shui)中(zhong)(zhong)通电运行(xing)几分钟(zhong)，清洗(xi)泵(beng)内外泥浆，然(ran)后提(ti)出水(shui)面擦(ca)干(gan)(gan)，进行(xing)一(yi)次大检(jian)查，拆(chai)开所有(you)部件(jian)进行(xing)检(jian)修(xiu)、擦(ca)洗(xi)、除锈(xiu)去垢，对(dui)易损(sun)件(jian)进行(xing)更换，再重新装配好，涂漆防锈(xiu)后放(fang)在(zai)(zai)干(gan)(gan)燥、无腐蚀(shi)性气(qi)体的(de)库房内
