一、產品簡介
QKSG系列潛(qian)(qian)水(shui)(shui)電(dian)(dian)泵(beng)(beng)由充水(shui)(shui)式潛(qian)(qian)水(shui)(shui)電(dian)(dian)機和(he)多級離(li)心泵(beng)(beng)組成(cheng),裝在吸罩內(nei)潛(qian)(qian)入(ru)水(shui)(shui)中工作(zuo)。這種潛(qian)(qian)水(shui)(shui)電(dian)(dian)泵(beng)(beng)較傳統離(li)心泵(beng)(beng)和(he)深井(jing)泵(beng)(beng)具有(you)(you)使用維(wei)護(hu)方(fang)便(bian),運(yun)行安全(quan)可靠,性能穩定,震動噪音(yin)小(xiao),效(xiao)率高(gao)等優(you)點,改善了泵(beng)(beng)房通風(feng)散熱(re)條件,有(you)(you)利環保(bao),運(yun)行費用低(di),可實行自動控制,對水(shui)(shui)位落差大(da)及(ji)有(you)(you)水(shui)(shui)患威(wei)脅的地方(fang)更(geng)有(you)(you)獨特的優(you)點,由于電(dian)(dian)機工作(zuo)時充滿(man)清水(shui)(shui),在任何情況下(xia)都不(bu)會產生(sheng)電(dian)(dian)火(huo)花引爆瓦斯,屬礦用一般安全(quan)型設(she)(she)備(bei)。為煤炭、冶金、電(dian)(dian)力(li)、城建(jian)、自來水(shui)(shui)及(ji)地下(xia)水(shui)(shui)開(kai)發等部門提供一種新型排、取水(shui)(shui)設(she)(she)備(bei)。
QKSG 型潛水電泵具有兩(liang)個吸入口,將兩(liang)組葉輪(lun)背靠背地對向(xiang)(xiang)分布,實際(ji)上是(shi)兩(liang)臺多(duo)級泵并聯連接,各有其吸水口(一(yi)個在上部,一(yi)個在下部)。由于兩(liang)組葉輪(lun)數量(liang)相等、方(fang)向(xiang)(xiang)相反,其產生的(de)水推力(li)大小相等方(fang)向(xiang)(xiang)相反,理(li)論上講總軸向(xiang)(xiang)水推力(li)為零。
QKSG-D型潛水電泵(beng)只有一(yi)個吸水口(kou),兩組葉(xie)輪(lun)(lun)也(ye)是背(bei)靠背(bei)對向(xiang)(xiang)分布(bu)。當泵(beng)揚程需葉(xie)輪(lun)(lun)總(zong)級(ji)數(shu)為偶數(shu)時,每組葉(xie)輪(lun)(lun)數(shu)量相(xiang)(xiang)等,方向(xiang)(xiang)相(xiang)(xiang)反,軸向(xiang)(xiang)水推(tui)力(li)(li)也(ye)為零。當泵(beng)揚程需葉(xie)輪(lun)(lun)級(ji)數(shu)為奇(qi)數(shu)時,則下泵(beng)葉(xie)輪(lun)(lun)多(duo)一(yi)級(ji),此時下泵(beng)末級(ji)葉(xie)輪(lun)(lun)被(bei)設(she)計為有平衡孔的(de)平衡葉(xie)輪(lun)(lun)。平衡葉(xie)輪(lun)(lun)產(chan)生(sheng)的(de)水推(tui)力(li)(li),基本上(shang)(shang)被(bei)消除。于是產(chan)生(sheng)軸向(xiang)(xiang)水推(tui)力(li)(li)的(de)兩組葉(xie)輪(lun)(lun)仍(reng)然數(shu)量相(xiang)(xiang)等、方向(xiang)(xiang)相(xiang)(xiang)反,總(zong)的(de)軸向(xiang)(xiang)力(li)(li)基本上(shang)(shang)為零。
軸向力(li)為零,推力(li)軸承(cheng)載荷輕(qing),壽命長(chang),運行可(ke)靠。是本系列潛水電(dian)泵重要技術特征。
QKSG潛水電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)是充水式三相(xiang)異(yi)步電(dian)(dian)(dian)(dian)(dian)動機(ji)(ji),功(gong)率≥600kW時(shi),在其轉子下端設有一小泵輪(lun),它使電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)內部充水循環以便對電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)進行冷卻;功(gong)率<600kW時(shi),轉子上帶(dai)螺旋水槽,同樣(yang)使充水循環以利電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)散熱。本電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)屬KY(礦用(yong)一般)型電(dian)(dian)(dian)(dian)(dian)機(ji)(ji),動力電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)為(wei)4芯(xin)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan),其中一芯(xin)為(wei)接地;信(xin)號電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)為(wei)8芯(xin)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan),其中4芯(xin)為(wei)溫度,2芯(xin)為(wei)水位,2芯(xin)備用(yong)。
