讓您潛水泵延年益壽的7個細節問題
現在市(shi)面上相關的潛(qian)水(shui)泵(beng)(beng)保(bao)(bao)(bao)護(hu)(hu)器(qi)很多，有漏(lou)(lou)水(shui)型(xing)潛(qian)水(shui)泵(beng)(beng)保(bao)(bao)(bao)護(hu)(hu)器(qi)、過(guo)熱型(xing)潛(qian)水(shui)泵(beng)(beng)保(bao)(bao)(bao)護(hu)(hu)器(qi)。其保(bao)(bao)(bao)護(hu)(hu)項(xiang)目涵蓋潛(qian)水(shui)泵(beng)(beng)油室(shi)漏(lou)(lou)水(shui)保(bao)(bao)(bao)護(hu)(hu)、電機漏(lou)(lou)水(shui)保(bao)(bao)(bao)護(hu)(hu)、線盒浸(jin)水(shui)保(bao)(bao)(bao)護(hu)(hu)、絕(jue)緣(yuan)電阻保(bao)(bao)(bao)護(hu)(hu)，繞(rao)組(zu)過(guo)熱保(bao)(bao)(bao)護(hu)(hu)、軸承(cheng)過(guo)熱保(bao)(bao)(bao)護(hu)(hu)等(deng)。但(dan)是為延(yan)長潛(qian)水(shui)泵(beng)(beng)的使(shi)用壽命，避免安全事故(gu)的發生(sheng)我們使(shi)用當中(zhong)還需要注意(yi)如下七個(ge)細(xi)節問(wen)題。
1、確認正確的(de)電(dian)機的(de)旋轉(zhuan)方向
應搞清電(dian)(dian)(dian)機(ji)的(de)旋轉(zhuan)(zhuan)方向，現(xian)在(zai)有許(xu)多(duo)類型的(de)潛水泵(beng)正轉(zhuan)(zhuan)和反(fan)轉(zhuan)(zhuan)時皆可出水，但(dan)反(fan)轉(zhuan)(zhuan)時出水量(liang)小、電(dian)(dian)(dian)流大，其反(fan)轉(zhuan)(zhuan)時間(jian)長了(le)會損壞電(dian)(dian)(dian)機(ji)繞(rao)組(zu)。
2、禁止電(dian)源電(dian)壓異常開機
由于(yu)(yu)(yu)低(di)壓(ya)(ya)供電(dian)(dian)線路比較長，線路的末端電(dian)(dian)壓(ya)(ya)過(guo)(guo)低(di)是常有(you)的事。當相電(dian)(dian)壓(ya)(ya)低(di)于(yu)(yu)(yu)198伏，線電(dian)(dian)壓(ya)(ya)低(di)于(yu)(yu)(yu)342伏時，潛(qian)水泵電(dian)(dian)機(ji)轉(zhuan)速(su)(su)下降，當達不到額定(ding)轉(zhuan)速(su)(su)的 70%時，啟(qi)動離(li)心開(kai)關會(hui)閉合，造成啟(qi)動繞組(zu)長時間通電(dian)(dian)而發熱(re)甚(shen)至燒壞繞組(zu)和電(dian)(dian)容器(qi)。相反，電(dian)(dian)壓(ya)(ya)過(guo)(guo)高(gao)引(yin)起電(dian)(dian)機(ji)過(guo)(guo)熱(re)而燒壞繞組(zu)。因(yin)此，潛(qian)水泵在作業中(zhong)，操作者必須(xu)隨(sui)時觀察(cha)電(dian)(dian)源電(dian)(dian)壓(ya)(ya)值，若低(di)于(yu)(yu)(yu)額定(ding)電(dian)(dian)壓(ya)(ya)10%以下，高(gao)于(yu)(yu)(yu)額定(ding)電(dian)(dian)壓(ya)(ya)10%以上，應使電(dian)(dian)機(ji)停止運轉(zhuan)，找出原(yuan)因(yin)并排除故障。
3、電纜(lan)線安(an)裝(zhuang)與潛水電泵的(de)絕緣(yuan)電阻要(yao)求
安裝潛(qian)(qian)水泵(beng)時，電(dian)(dian)(dian)纜線要架空(kong)，電(dian)(dian)(dian)源線不要太長。潛(qian)(qian)水泵(beng)下水或提出時切勿(wu)使(shi)電(dian)(dian)(dian)纜受力，以免引起電(dian)(dian)(dian)源線斷裂。潛(qian)(qian)水泵(beng)工作時不要沉入泥中(zhong)，否則(ze)會導致電(dian)(dian)(dian)機(ji)散熱不良而(er)燒壞電(dian)(dian)(dian)機(ji)繞組。安裝時，電(dian)(dian)(dian)機(ji)的絕緣電(dian)(dian)(dian)阻不應低于0.5兆歐。
4、漏電(dian)保護器的安裝
漏(lou)電(dian)(dian)保(bao)(bao)護(hu)(hu)器也叫(jiao)保(bao)(bao)命器，它的作用從“保(bao)(bao)命器”這三個字就(jiu)可以理解(jie)。因為潛水(shui)泵(beng)在水(shui)下(xia)工(gong)作，容(rong)易漏(lou)電(dian)(dian)造(zao)成電(dian)(dian)能損失甚(shen)至引發觸電(dian)(dian)事故(gu)。如果裝有漏(lou)電(dian)(dian)保(bao)(bao)護(hu)(hu)器，只(zhi)要潛水(shui)泵(beng)漏(lou)電(dian)(dian)值超過(guo)漏(lou)電(dian)(dian)保(bao)(bao)護(hu)(hu)器的動作電(dian)(dian)流(liu)值（一般不超過(guo)30毫安(an)），漏(lou)電(dian)(dian)保(bao)(bao)護(hu)(hu)器就(jiu)會切斷潛水(shui)泵(beng)的電(dian)(dian)源，確保(bao)(bao)安(an)全，同(tong)時(shi)避免(mian)漏(lou)電(dian)(dian)、浪費電(dian)(dian)能。
5、避免頻繁開關(guan)
不要頻(pin)繁地開(kai)關潛(qian)水泵，這是因(yin)為電泵停(ting)轉時會產生回流，若立(li)即(ji)開(kai)機(ji)，會使電機(ji)負(fu)載啟(qi)動，導致啟(qi)動電流過大而燒(shao)壞繞組。由于啟(qi)動時電流很大，頻(pin)繁啟(qi)動也會燒(shao)壞潛(qian)水泵電動機(ji)繞組。
6、莫讓潛水電泵長期超負荷工作
為避免潛水電泵(beng)長(chang)期超(chao)負荷工(gong)作，不要抽含沙量(liang)大的(de)水并隨時(shi)觀(guan)察(cha)電流值是否在銘牌上規定的(de)數值，若發(fa)現(xian)電流過(guo)大，應(ying)停(ting)機檢查(cha)。另外(wai)，電泵(beng)脫水運行的(de)時(shi)間不宜(yi)過(guo)長(chang)，以免使電機過(guo)熱而燒毀。
7、注重日常維護
平時要經常檢查電機，如發現下蓋有裂紋、橡膠密(mi)封(feng)環(huan)損(sun)壞或失效等，應及時更換或修復，避免水滲入(ru)潛水泵。
潛水(shui)(shui)泵保護器(qi)的運用和注重一些日常的保護能(neng)更(geng)好的延長(chang)潛水(shui)(shui)泵的使用壽命。
