潛水泵通電后不出水的原因及處理方法
1、電源電壓過低、未能起動
潛水泵(beng)因(yin)電源電壓過低(di)未(wei)能起動,應將(jiang)電壓跳到342V以上。
2、定子線圈斷路
處(chu)理(li)方法是檢查(cha)定子(zi)線圈斷路處(chu),修理(li)潛水泵的定子(zi)繞(rao)組。
3、導軸承與軸的間隙太小
充水(shui)式潛水(shui)泵導軸(zhou)(zhou)(zhou)承(cheng)與軸(zhou)(zhou)(zhou)的間(jian)隙太小,運行時(shi)輕易因導軸(zhou)(zhou)(zhou)承(cheng)水(shui)脹(zhang)或發燒,使軸(zhou)(zhou)(zhou)承(cheng)產(chan)生(sheng)抱(bao)軸(zhou)(zhou)(zhou)現象(xiang)。
4、潛水泵使用后長期放置,致使水泵葉輪與口環部位銹蝕,尤其是對導葉式潛水泵
處理方法是拆開水(shui)泵(beng)的(de)(de)上導流(liu)殼,清理銹蝕部位,使潛(qian)(qian)水(shui)泵(beng)能靈活(huo)滾動。同時檢查潛(qian)(qian)水(shui)泵(beng)定(ding)(ding)子(zi)線圈(quan)短路(lu)的(de)(de)原(yuan)因,排出潛(qian)(qian)水(shui)泵(beng)存在的(de)(de)故障,避免潛(qian)(qian)水(shui)泵(beng)定(ding)(ding)子(zi)線圈(quan)再次發(fa)生短路(lu)。假如由于(yu)各種原(yuan)因電(dian)壓調不到342V,而潛(qian)(qian)水(shui)泵(beng)又(you)必需使用,可適當調大潛(qian)(qian)水(shui)泵(beng)保(bao)護(hu)開關(guan)的(de)(de)整定(ding)(ding)電(dian)流(liu)。
5、定子線圈短路
處理(li)方法是檢查定子線圈短(duan)路處,修(xiu)理(li)潛(qian)水泵的定子繞組。
6、充水式潛水泵內腔沖水不足發生抱軸現象
處理(li)方(fang)法是(shi)修理(li)或更換損壞的軸承,同時對充水(shui)式(shi)潛水(shui)泵(beng),應確保內腔(qiang)布滿凈水(shui)。
7、潛水泵的供電電纜過細或過長
潛水泵的供電電纜過(guo)細或過(guo)長(chang),會造成電纜壓降過(guo)大、使潛水泵電壓過(guo)低,無法(fa)起(qi)動。
8、潛水泵葉輪卡住
處(chu)理方法是(shi)(shi)拆卸水(shui)泵(beng)、清除葉輪雜物(wu)、修復水(shui)泵(beng)。但使用時應(ying)(ying)控制(zhi)電(dian)(dian)(dian)流(liu)不(bu)超(chao)過(guo)電(dian)(dian)(dian)念頭的(de)額定電(dian)(dian)(dian)流(liu)的(de)1.1倍(bei),并控制(zhi)使用時間(jian),使電(dian)(dian)(dian)念頭不(bu)致因超(chao)載過(guo)久,造成定子繞(rao)組(zu)過(guo)熱損壞。處(chu)理方法是(shi)(shi)仔細檢查熔(rong)斷器(qi)(qi)、控制(zhi)保(bao)護(hu)開(kai)關和保(bao)護(hu)裝(zhuang)置,檢查是(shi)(shi)否(fou)因電(dian)(dian)(dian)源斷相(xiang)(xiang)或斷電(dian)(dian)(dian),或是(shi)(shi)因熔(rong)斷器(qi)(qi)、開(kai)關和保(bao)護(hu)裝(zhuang)置動(dong)作(zuo)或接(jie)觸不(bu)良(liang)造成斷相(xiang)(xiang)或斷電(dian)(dian)(dian)。當(dang)潛水(shui)泵(beng)的(de)使用場(chang)所距供電(dian)(dian)(dian)電(dian)(dian)(dian)源較遠、電(dian)(dian)(dian)纜(lan)較長(chang)(chang)、電(dian)(dian)(dian)壓降過(guo)大(da)時,應(ying)(ying)適當(dang)加粗電(dian)(dian)(dian)纜(lan)截面:電(dian)(dian)(dian)纜(lan)長(chang)(chang)度假如增加一(yi)倍(bei),電(dian)(dian)(dian)纜(lan)截面也應(ying)(ying)相(xiang)(xiang)應(ying)(ying)增加一(yi)倍(bei)。
9、電源斷相或斷電
電(dian)纜斷(duan)(duan)(duan)(duan)裂、熔(rong)斷(duan)(duan)(duan)(duan)器(qi)熔(rong)斷(duan)(duan)(duan)(duan)、控制保護(hu)開(kai)關接觸(chu)不良、控制保護(hu)裝(zhuang)置動(dong)作等,會造成(cheng)潛(qian)(qian)電(dian)泵(beng)(beng)(beng)不能起(qi)動(dong)。修復因(yin)熔(rong)斷(duan)(duan)(duan)(duan)器(qi)、開(kai)關和保護(hu)裝(zhuang)置造成(cheng)的(de)斷(duan)(duan)(duan)(duan)電(dian)或斷(duan)(duan)(duan)(duan)相處(chu)。處(chu)理方法是(shi)修理導(dao)軸(zhou)(zhou)承:按(an)照劃定要求,適當加大(da)導(dao)軸(zhou)(zhou)承與軸(zhou)(zhou)的(de)間隙,使(shi)潛(qian)(qian)水(shui)泵(beng)(beng)(beng)運行時,軸(zhou)(zhou)承不再(zai)發(fa)生抱軸(zhou)(zhou)現象(xiang)。處(chu)理方法是(shi)按(an)供(gong)電(dian)電(dian)纜的(de)公道選擇要求調換較粗的(de)電(dian)纜,減少電(dian)纜電(dian)壓降。同時檢查潛(qian)(qian)水(shui)泵(beng)(beng)(beng)定子(zi)線(xian)圈斷(duan)(duan)(duan)(duan)路的(de)原因(yin),排(pai)出潛(qian)(qian)水(shui)泵(beng)(beng)(beng)存在(zai)的(de)故障(zhang),避免潛(qian)(qian)水(shui)泵(beng)(beng)(beng)定子(zi)線(xian)圈再(zai)次(ci)發(fa)生斷(duan)(duan)(duan)(duan)路。這樣(yang)可以進步潛(qian)(qian)水(shui)泵(beng)(beng)(beng)的(de)起(qi)動(dong)電(dian)壓,使(shi)潛(qian)(qian)水(shui)泵(beng)(beng)(beng)輕易(yi)起(qi)動(dong)。
