一(yi)、產(chan)品簡介
QKSG系列潛(qian)水(shui)電(dian)泵(beng)(beng)由充(chong)水(shui)式潛(qian)水(shui)電(dian)機和(he)多級(ji)離心泵(beng)(beng)組成,裝(zhuang)在(zai)吸(xi)罩(zhao)內潛(qian)入水(shui)中工作。這種(zhong)潛(qian)水(shui)電(dian)泵(beng)(beng)較傳統離心泵(beng)(beng)和(he)深井泵(beng)(beng)具有使(shi)用維護方(fang)便,運行安全可靠(kao),性能穩定(ding),震(zhen)動噪音小,效率(lv)高等優(you)(you)點(dian),改善(shan)了泵(beng)(beng)房通風散熱條件,有利環保,運行費用低,可實行自(zi)動控制,對水(shui)位落差大及有水(shui)患威脅的地方(fang)更有獨(du)特的優(you)(you)點(dian),由于電(dian)機工作時充(chong)滿清水(shui),在(zai)任何情(qing)況下(xia)都(dou)不(bu)會產生(sheng)電(dian)火花引爆(bao)瓦斯,屬礦用一般安全型設備。為煤(mei)炭、冶(ye)金、電(dian)力(li)、城建、自(zi)來水(shui)及地下(xia)水(shui)開發等部門提供(gong)一種(zhong)新(xin)型排、取水(shui)設備。
QKSG 型(xing)潛(qian)水電(dian)泵具有兩(liang)個(ge)吸(xi)入口,將兩(liang)組(zu)(zu)葉輪背(bei)靠背(bei)地對(dui)向(xiang)分布,實際上(shang)是兩(liang)臺(tai)多級(ji)泵并(bing)聯連接,各有其吸(xi)水口(一(yi)(yi)個(ge)在(zai)上(shang)部,一(yi)(yi)個(ge)在(zai)下部)。由(you)于(yu)兩(liang)組(zu)(zu)葉輪數量相(xiang)等(deng)、方向(xiang)相(xiang)反(fan),其產生的水推力(li)大小相(xiang)等(deng)方向(xiang)相(xiang)反(fan),理論上(shang)講總軸(zhou)向(xiang)水推力(li)為零。
QKSG-D型潛水(shui)電泵只有一(yi)個(ge)吸水(shui)口(kou),兩組(zu)(zu)葉(xie)(xie)輪(lun)(lun)(lun)也是(shi)背靠背對(dui)向分(fen)布。當(dang)泵揚程需葉(xie)(xie)輪(lun)(lun)(lun)總級數為(wei)偶數時(shi)(shi),每組(zu)(zu)葉(xie)(xie)輪(lun)(lun)(lun)數量相(xiang)等(deng),方(fang)向相(xiang)反,軸向水(shui)推(tui)(tui)力也為(wei)零。當(dang)泵揚程需葉(xie)(xie)輪(lun)(lun)(lun)級數為(wei)奇數時(shi)(shi),則下泵葉(xie)(xie)輪(lun)(lun)(lun)多一(yi)級,此時(shi)(shi)下泵末(mo)級葉(xie)(xie)輪(lun)(lun)(lun)被(bei)設計為(wei)有平衡孔的(de)平衡葉(xie)(xie)輪(lun)(lun)(lun)。平衡葉(xie)(xie)輪(lun)(lun)(lun)產(chan)生的(de)水(shui)推(tui)(tui)力,基本上被(bei)消除。于是(shi)產(chan)生軸向水(shui)推(tui)(tui)力的(de)兩組(zu)(zu)葉(xie)(xie)輪(lun)(lun)(lun)仍然數量相(xiang)等(deng)、方(fang)向相(xiang)反,總的(de)軸向力基本上為(wei)零。
軸向力為零,推(tui)力軸承載荷輕,壽命長,運行可靠。是(shi)本系列潛水電泵重(zhong)要技術(shu)特征。
QKSG潛水(shui)(shui)(shui)電(dian)(dian)(dian)(dian)(dian)機是充(chong)水(shui)(shui)(shui)式三相(xiang)異(yi)步電(dian)(dian)(dian)(dian)(dian)動機,功率≥600kW時,在其(qi)轉(zhuan)子下端設有一(yi)(yi)小泵輪,它(ta)使電(dian)(dian)(dian)(dian)(dian)機內部充(chong)水(shui)(shui)(shui)循環以便對電(dian)(dian)(dian)(dian)(dian)機進行冷卻;功率<600kW時,轉(zhuan)子上帶螺旋水(shui)(shui)(shui)槽,同樣使充(chong)水(shui)(shui)(shui)循環以利(li)電(dian)(dian)(dian)(dian)(dian)機散熱。本電(dian)(dian)(dian)(dian)(dian)機屬KY(礦(kuang)用一(yi)(yi)般)型(xing)電(dian)(dian)(dian)(dian)(dian)機,動力電(dian)(dian)(dian)(dian)(dian)纜為(wei)(wei)4芯電(dian)(dian)(dian)(dian)(dian)纜,其(qi)中一(yi)(yi)芯為(wei)(wei)接地(di);信號電(dian)(dian)(dian)(dian)(dian)纜為(wei)(wei)8芯電(dian)(dian)(dian)(dian)(dian)纜,其(qi)中4芯為(wei)(wei)溫度,2芯為(wei)(wei)水(shui)(shui)(shui)位,2芯備用。
