一、產(chan)品(pin)簡(jian)介
QKSG系列潛水(shui)(shui)電(dian)(dian)(dian)(dian)泵由充水(shui)(shui)式潛水(shui)(shui)電(dian)(dian)(dian)(dian)機(ji)(ji)和多級離心泵組成,裝在(zai)吸罩(zhao)內潛入(ru)水(shui)(shui)中工(gong)作。這種(zhong)潛水(shui)(shui)電(dian)(dian)(dian)(dian)泵較傳統離心泵和深(shen)井(jing)泵具有使用(yong)維護方便,運行安(an)全可靠(kao),性能(neng)穩定,震動噪音小,效率高等(deng)(deng)優點(dian),改善了泵房通風散熱條件(jian),有利環保,運行費用(yong)低,可實行自動控制,對水(shui)(shui)位落差(cha)大及(ji)有水(shui)(shui)患(huan)威脅(xie)的地(di)方更有獨特(te)的優點(dian),由于(yu)電(dian)(dian)(dian)(dian)機(ji)(ji)工(gong)作時充滿清水(shui)(shui),在(zai)任何情況下都(dou)不會產生電(dian)(dian)(dian)(dian)火花引爆瓦斯,屬礦用(yong)一(yi)般(ban)安(an)全型(xing)設(she)備。為(wei)煤炭、冶金、電(dian)(dian)(dian)(dian)力(li)、城建、自來水(shui)(shui)及(ji)地(di)下水(shui)(shui)開發等(deng)(deng)部(bu)門提(ti)供一(yi)種(zhong)新型(xing)排、取水(shui)(shui)設(she)備。
QKSG 型潛(qian)水電泵具有兩個吸入口(kou),將兩組葉(xie)輪背靠(kao)背地對(dui)向(xiang)分(fen)布(bu),實際上是兩臺多級泵并聯連接,各有其吸水口(kou)(一(yi)個在(zai)上部,一(yi)個在(zai)下部)。由于兩組葉(xie)輪數量相等、方(fang)向(xiang)相反(fan),其產(chan)生的(de)水推力大小(xiao)相等方(fang)向(xiang)相反(fan),理(li)論上講(jiang)總軸向(xiang)水推力為零(ling)。
QKSG-D型潛水(shui)(shui)電泵(beng)只有(you)一個(ge)吸水(shui)(shui)口,兩組(zu)葉輪(lun)(lun)也是背靠背對向(xiang)(xiang)(xiang)分布。當泵(beng)揚程(cheng)需葉輪(lun)(lun)總級(ji)數(shu)(shu)(shu)為(wei)偶數(shu)(shu)(shu)時(shi),每組(zu)葉輪(lun)(lun)數(shu)(shu)(shu)量相(xiang)等,方(fang)向(xiang)(xiang)(xiang)相(xiang)反(fan),軸(zhou)(zhou)向(xiang)(xiang)(xiang)水(shui)(shui)推(tui)力(li)也為(wei)零(ling)。當泵(beng)揚程(cheng)需葉輪(lun)(lun)級(ji)數(shu)(shu)(shu)為(wei)奇數(shu)(shu)(shu)時(shi),則下泵(beng)葉輪(lun)(lun)多(duo)一級(ji),此時(shi)下泵(beng)末(mo)級(ji)葉輪(lun)(lun)被(bei)設計為(wei)有(you)平(ping)(ping)衡孔(kong)的平(ping)(ping)衡葉輪(lun)(lun)。平(ping)(ping)衡葉輪(lun)(lun)產生(sheng)的水(shui)(shui)推(tui)力(li),基(ji)本(ben)上(shang)被(bei)消除。于是產生(sheng)軸(zhou)(zhou)向(xiang)(xiang)(xiang)水(shui)(shui)推(tui)力(li)的兩組(zu)葉輪(lun)(lun)仍(reng)然數(shu)(shu)(shu)量相(xiang)等、方(fang)向(xiang)(xiang)(xiang)相(xiang)反(fan),總的軸(zhou)(zhou)向(xiang)(xiang)(xiang)力(li)基(ji)本(ben)上(shang)為(wei)零(ling)。
軸向力為(wei)零,推力軸承(cheng)載(zai)荷(he)輕(qing),壽命長,運行可靠。是本系列潛(qian)水電泵重要(yao)技(ji)術特征。
QKSG潛水(shui)電(dian)(dian)(dian)(dian)機(ji)(ji)是充水(shui)式三(san)相異步電(dian)(dian)(dian)(dian)動機(ji)(ji),功率≥600kW時(shi),在(zai)其轉子(zi)下端設有一小泵輪,它使電(dian)(dian)(dian)(dian)機(ji)(ji)內(nei)部充水(shui)循(xun)環以(yi)便對電(dian)(dian)(dian)(dian)機(ji)(ji)進行冷卻;功率<600kW時(shi),轉子(zi)上(shang)帶螺(luo)旋(xuan)水(shui)槽(cao),同樣(yang)使充水(shui)循(xun)環以(yi)利(li)電(dian)(dian)(dian)(dian)機(ji)(ji)散熱。本電(dian)(dian)(dian)(dian)機(ji)(ji)屬KY(礦用一般)型(xing)電(dian)(dian)(dian)(dian)機(ji)(ji),動力電(dian)(dian)(dian)(dian)纜(lan)(lan)為(wei)4芯(xin)電(dian)(dian)(dian)(dian)纜(lan)(lan),其中(zhong)(zhong)一芯(xin)為(wei)接地;信號(hao)電(dian)(dian)(dian)(dian)纜(lan)(lan)為(wei)8芯(xin)電(dian)(dian)(dian)(dian)纜(lan)(lan),其中(zhong)(zhong)4芯(xin)為(wei)溫度(du),2芯(xin)為(wei)水(shui)位(wei),2芯(xin)備用。
