潛(qian)水攪拌(ban)(ban)機在污(wu)(wu)水處(chu)理(li)(li)廠適用,潛(qian)水攪拌(ban)(ban)機的工藝流程中推進攪拌(ban)(ban)含有懸浮物的稀(xi)泥漿(jiang)、污(wu)(wu)水、工業過程液體等,能夠(gou)創(chuang)建水流,使攪拌(ban)(ban)功能加強(qiang),不讓(rang)污(wu)(wu)泥進行沉(chen)淀(dian),在市政以(yi)及工業污(wu)(wu)水處(chu)理(li)(li)工藝流程上發(fa)揮了(le)很重要的作用。
潛(qian)水泵(beng)小巧輕便,在(zai)農(nong)村生(sheng)產生(sheng)活中起著重要作用,在(zai)選(xuan)購和使用中應注意以下(xia)幾點:
一、選購
選(xuan)購潛水(shui)泵時(shi)(shi)應留(liu)意其型號、流量和(he)揚程。如選(xuan)用的規格不恰當,將無法獲(huo)得足夠(gou)的出水(shui)量,不能發揮機(ji)組(zu)的效率。另外,還應搞清電(dian)(dian)機(ji)的旋轉(zhuan)(zhuan)(zhuan)方向(xiang),某些(xie)類(lei)型的潛水(shui)泵正轉(zhuan)(zhuan)(zhuan)和(he)反轉(zhuan)(zhuan)(zhuan)時(shi)(shi)皆可(ke)出水(shui),但反轉(zhuan)(zhuan)(zhuan)時(shi)(shi)出水(shui)量小、電(dian)(dian)流大,其反轉(zhuan)(zhuan)(zhuan)會損壞電(dian)(dian)機(ji)繞組(zu)。為防(fang)止潛水(shui)泵在水(shui)下工作時(shi)(shi)漏電(dian)(dian)而(er)引發觸電(dian)(dian)事(shi)故,應裝漏電(dian)(dian)保護開關。
二、安裝
安裝潛(qian)水(shui)泵(beng)時,電(dian)纜線要(yao)架空,電(dian)源(yuan)線不(bu)要(yao)太長。機(ji)組下水(shui)時切勿使電(dian)纜受力,以免引起電(dian)源(yuan)線斷裂。潛(qian)水(shui)泵(beng)不(bu)要(yao)沉(chen)入泥中,否(fou)則(ze)會導致(zhi)散熱不(bu)良而燒(shao)壞(huai)電(dian)機(ji)繞組。
三、使用
1.盡量避免在低壓(ya)時(shi)開機(ji)(ji)。電(dian)(dian)源電(dian)(dian)壓(ya)與(yu)額(e)(e)定(ding)電(dian)(dian)壓(ya)不可相(xiang)差10%,電(dian)(dian)壓(ya)過高會引起電(dian)(dian)機(ji)(ji)過熱(re)而燒壞(huai)(huai)繞組(zu)(zu),電(dian)(dian)壓(ya)過低則(ze)電(dian)(dian)機(ji)(ji)轉(zhuan)(zhuan)速下降(jiang),如達不到額(e)(e)定(ding)轉(zhuan)(zhuan)速的70%時(shi),啟(qi)動(dong)(dong)離心(xin)開關(guan)會閉合,造成啟(qi)動(dong)(dong)繞組(zu)(zu)長時(shi)間通電(dian)(dian)而發熱(re)甚至燒壞(huai)(huai)繞組(zu)(zu)和電(dian)(dian)容器(qi)。轉(zhuan)(zhuan)子泵不要頻繁地開關(guan)電(dian)(dian)機(ji)(ji),這是因為(wei)電(dian)(dian)泵停轉(zhuan)(zhuan)時(shi)會產生回流,若立(li)即開機(ji)(ji),會使(shi)電(dian)(dian)機(ji)(ji)負載啟(qi)動(dong)(dong),導致啟(qi)動(dong)(dong)電(dian)(dian)流過大而燒壞(huai)(huai)繞組(zu)(zu)。
2.切莫讓(rang)水泵(beng)長期超負荷運(yun)(yun)轉(zhuan),不要抽含沙(sha)量大的水,電(dian)泵(beng)脫水運(yun)(yun)行的時(shi)間不宜過長,以免使電(dian)機過熱(re)而燒毀。機組(zu)在(zai)作業中,操作者必(bi)須隨時(shi)觀察其工作電(dian)壓和電(dian)流是(shi)否在(zai)銘牌上規定的數值(zhi)內(nei),若不符合應使電(dian)機停止運(yun)(yun)轉(zhuan),找出(chu)原因(yin)并(bing)排除(chu)故(gu)障。
3.平時多檢查電機,如(ru)發現下(xia)蓋有裂紋、橡膠密封(feng)環(huan)損壞或失效等,應及時更(geng)換或修(xiu)復,以防(fang)水滲入機器(qi)。
