一、產(chan)品簡(jian)介
QKSG系列(lie)潛水(shui)(shui)(shui)(shui)電(dian)(dian)泵(beng)由充水(shui)(shui)(shui)(shui)式潛水(shui)(shui)(shui)(shui)電(dian)(dian)機和多(duo)級離心(xin)泵(beng)組(zu)成,裝在吸罩內潛入水(shui)(shui)(shui)(shui)中工作。這種潛水(shui)(shui)(shui)(shui)電(dian)(dian)泵(beng)較傳(chuan)統離心(xin)泵(beng)和深(shen)井泵(beng)具(ju)有使用(yong)(yong)維護方(fang)便(bian),運(yun)行(xing)安全(quan)(quan)可靠(kao),性能穩定,震動(dong)噪音(yin)小(xiao),效率高等(deng)優(you)點(dian),改善了(le)泵(beng)房通風散熱條件,有利環保,運(yun)行(xing)費用(yong)(yong)低,可實行(xing)自動(dong)控制,對水(shui)(shui)(shui)(shui)位落差大及(ji)有水(shui)(shui)(shui)(shui)患威脅的(de)地方(fang)更有獨特(te)的(de)優(you)點(dian),由于(yu)電(dian)(dian)機工作時充滿清水(shui)(shui)(shui)(shui),在任何情(qing)況下都(dou)不會(hui)產生電(dian)(dian)火花引爆(bao)瓦斯,屬礦用(yong)(yong)一(yi)般安全(quan)(quan)型設備(bei)。為煤炭、冶金、電(dian)(dian)力、城(cheng)建(jian)、自來水(shui)(shui)(shui)(shui)及(ji)地下水(shui)(shui)(shui)(shui)開發等(deng)部門提供一(yi)種新型排、取水(shui)(shui)(shui)(shui)設備(bei)。
QKSG 型潛水電泵(beng)(beng)具有兩個(ge)(ge)吸入口(kou),將兩組(zu)葉(xie)輪背靠背地對(dui)向分布(bu),實際上是兩臺多級泵(beng)(beng)并(bing)聯連接,各有其吸水口(kou)(一個(ge)(ge)在上部(bu),一個(ge)(ge)在下部(bu))。由于兩組(zu)葉(xie)輪數量(liang)相等、方(fang)向相反(fan),其產生的水推(tui)力大小相等方(fang)向相反(fan),理論上講總(zong)軸向水推(tui)力為零(ling)。
QKSG-D型潛水電泵(beng)只有(you)一個吸水口,兩組(zu)(zu)葉(xie)輪(lun)也是(shi)背(bei)靠背(bei)對向(xiang)(xiang)(xiang)分布。當泵(beng)揚(yang)程需葉(xie)輪(lun)總級(ji)(ji)數(shu)為(wei)偶數(shu)時(shi),每(mei)組(zu)(zu)葉(xie)輪(lun)數(shu)量相(xiang)等,方(fang)向(xiang)(xiang)(xiang)相(xiang)反,軸向(xiang)(xiang)(xiang)水推力也為(wei)零。當泵(beng)揚(yang)程需葉(xie)輪(lun)級(ji)(ji)數(shu)為(wei)奇數(shu)時(shi),則下泵(beng)葉(xie)輪(lun)多(duo)一級(ji)(ji),此(ci)時(shi)下泵(beng)末級(ji)(ji)葉(xie)輪(lun)被(bei)設計為(wei)有(you)平(ping)衡孔(kong)的(de)平(ping)衡葉(xie)輪(lun)。平(ping)衡葉(xie)輪(lun)產生(sheng)的(de)水推力,基本(ben)上被(bei)消(xiao)除。于是(shi)產生(sheng)軸向(xiang)(xiang)(xiang)水推力的(de)兩組(zu)(zu)葉(xie)輪(lun)仍(reng)然數(shu)量相(xiang)等、方(fang)向(xiang)(xiang)(xiang)相(xiang)反,總的(de)軸向(xiang)(xiang)(xiang)力基本(ben)上為(wei)零。
軸向力為零,推力軸承載荷(he)輕,壽命長,運行可靠(kao)。是(shi)本系(xi)列(lie)潛水電泵重要(yao)技(ji)術特征。
QKSG潛水(shui)電(dian)(dian)(dian)(dian)機(ji)是充水(shui)式三相異步電(dian)(dian)(dian)(dian)動機(ji),功率(lv)≥600kW時(shi),在其(qi)轉(zhuan)子下端設有一小泵輪,它使(shi)電(dian)(dian)(dian)(dian)機(ji)內部充水(shui)循環以便對(dui)電(dian)(dian)(dian)(dian)機(ji)進(jin)行冷卻;功率(lv)<600kW時(shi),轉(zhuan)子上帶螺(luo)旋(xuan)水(shui)槽,同樣(yang)使(shi)充水(shui)循環以利電(dian)(dian)(dian)(dian)機(ji)散(san)熱。本(ben)電(dian)(dian)(dian)(dian)機(ji)屬KY(礦用一般)型電(dian)(dian)(dian)(dian)機(ji),動力電(dian)(dian)(dian)(dian)纜(lan)為(wei)(wei)4芯電(dian)(dian)(dian)(dian)纜(lan),其(qi)中一芯為(wei)(wei)接地;信號電(dian)(dian)(dian)(dian)纜(lan)為(wei)(wei)8芯電(dian)(dian)(dian)(dian)纜(lan),其(qi)中4芯為(wei)(wei)溫(wen)度,2芯為(wei)(wei)水(shui)位,2芯備(bei)用。
