一(yi)、產品簡介
QKSG系(xi)列(lie)潛(qian)水電(dian)(dian)泵(beng)由(you)充水式潛(qian)水電(dian)(dian)機(ji)和(he)多級離心(xin)泵(beng)組成,裝在吸罩內潛(qian)入水中工作。這(zhe)種潛(qian)水電(dian)(dian)泵(beng)較傳統離心(xin)泵(beng)和(he)深井泵(beng)具有(you)(you)使用(yong)維護(hu)方(fang)便,運行安全可靠(kao),性能(neng)穩(wen)定,震動噪音小,效(xiao)率高等優點(dian)(dian),改(gai)善(shan)了(le)泵(beng)房通(tong)風(feng)散熱(re)條件,有(you)(you)利環保,運行費(fei)用(yong)低,可實行自動控制,對水位落差(cha)大及有(you)(you)水患威脅的地方(fang)更有(you)(you)獨特的優點(dian)(dian),由(you)于電(dian)(dian)機(ji)工作時充滿清水,在任何情況下(xia)都不會產生電(dian)(dian)火花引(yin)爆瓦(wa)斯,屬(shu)礦用(yong)一般安全型(xing)設備。為煤炭、冶金、電(dian)(dian)力(li)、城(cheng)建(jian)、自來水及地下(xia)水開發(fa)等部門提供一種新型(xing)排、取水設備。
QKSG 型潛水電泵(beng)具(ju)有兩個(ge)吸入口(kou),將兩組葉(xie)(xie)輪背靠背地(di)對向(xiang)(xiang)分布,實際上(shang)是兩臺多級泵(beng)并聯連接,各有其(qi)吸水口(kou)(一(yi)個(ge)在(zai)上(shang)部,一(yi)個(ge)在(zai)下(xia)部)。由于兩組葉(xie)(xie)輪數(shu)量相等(deng)、方(fang)(fang)向(xiang)(xiang)相反,其(qi)產生的水推(tui)力(li)大小相等(deng)方(fang)(fang)向(xiang)(xiang)相反,理論上(shang)講總(zong)軸向(xiang)(xiang)水推(tui)力(li)為零。
QKSG-D型潛(qian)水(shui)(shui)電泵(beng)(beng)(beng)只有一個吸水(shui)(shui)口,兩組葉(xie)(xie)(xie)輪(lun)(lun)也是(shi)背靠背對向分布。當泵(beng)(beng)(beng)揚程需(xu)葉(xie)(xie)(xie)輪(lun)(lun)總級(ji)數為(wei)偶數時,每(mei)組葉(xie)(xie)(xie)輪(lun)(lun)數量相(xiang)等,方向相(xiang)反(fan),軸向水(shui)(shui)推力(li)也為(wei)零(ling)。當泵(beng)(beng)(beng)揚程需(xu)葉(xie)(xie)(xie)輪(lun)(lun)級(ji)數為(wei)奇數時,則下泵(beng)(beng)(beng)葉(xie)(xie)(xie)輪(lun)(lun)多(duo)一級(ji),此時下泵(beng)(beng)(beng)末級(ji)葉(xie)(xie)(xie)輪(lun)(lun)被(bei)設計為(wei)有平(ping)衡孔的(de)(de)平(ping)衡葉(xie)(xie)(xie)輪(lun)(lun)。平(ping)衡葉(xie)(xie)(xie)輪(lun)(lun)產(chan)生的(de)(de)水(shui)(shui)推力(li),基本上被(bei)消(xiao)除。于是(shi)產(chan)生軸向水(shui)(shui)推力(li)的(de)(de)兩組葉(xie)(xie)(xie)輪(lun)(lun)仍然數量相(xiang)等、方向相(xiang)反(fan),總的(de)(de)軸向力(li)基本上為(wei)零(ling)。
軸向力為零,推力軸承載荷輕,壽命長,運行(xing)可靠(kao)。是(shi)本(ben)系列(lie)潛水電泵重要(yao)技術(shu)特征。
QKSG潛水(shui)電(dian)(dian)(dian)機(ji)是(shi)充水(shui)式三相(xiang)異步電(dian)(dian)(dian)動(dong)機(ji),功(gong)(gong)率(lv)≥600kW時,在(zai)其(qi)轉(zhuan)子下端設(she)有(you)一(yi)(yi)小(xiao)泵輪(lun),它(ta)使電(dian)(dian)(dian)機(ji)內(nei)部充水(shui)循環以便對電(dian)(dian)(dian)機(ji)進行冷卻;功(gong)(gong)率(lv)<600kW時,轉(zhuan)子上帶螺旋水(shui)槽,同樣(yang)使充水(shui)循環以利電(dian)(dian)(dian)機(ji)散熱。本電(dian)(dian)(dian)機(ji)屬(shu)KY(礦用(yong)一(yi)(yi)般)型電(dian)(dian)(dian)機(ji),動(dong)力電(dian)(dian)(dian)纜(lan)(lan)為(wei)(wei)4芯(xin)(xin)電(dian)(dian)(dian)纜(lan)(lan),其(qi)中一(yi)(yi)芯(xin)(xin)為(wei)(wei)接地;信(xin)號(hao)電(dian)(dian)(dian)纜(lan)(lan)為(wei)(wei)8芯(xin)(xin)電(dian)(dian)(dian)纜(lan)(lan),其(qi)中4芯(xin)(xin)為(wei)(wei)溫度,2芯(xin)(xin)為(wei)(wei)水(shui)位,2芯(xin)(xin)備用(yong)。
