一、產品簡介(jie)
QKSG系(xi)列潛水電(dian)(dian)泵(beng)由(you)充水式潛水電(dian)(dian)機(ji)和多級(ji)離(li)心泵(beng)組成,裝在(zai)吸罩內潛入水中工作。這(zhe)種潛水電(dian)(dian)泵(beng)較(jiao)傳統離(li)心泵(beng)和深(shen)井泵(beng)具有使(shi)用維護方便,運行(xing)安(an)全可靠,性能穩(wen)定,震動噪(zao)音小(xiao),效率高等優(you)點(dian),改(gai)善了泵(beng)房通風(feng)散(san)熱條件,有利環保,運行(xing)費用低,可實行(xing)自動控制,對水位落差大(da)及有水患威脅(xie)的地(di)方更有獨(du)特的優(you)點(dian),由(you)于電(dian)(dian)機(ji)工作時充滿清水,在(zai)任何(he)情況下都不會產生電(dian)(dian)火(huo)花引爆(bao)瓦斯,屬礦(kuang)用一般安(an)全型(xing)設備(bei)。為煤炭、冶金、電(dian)(dian)力、城(cheng)建、自來水及地(di)下水開發等部門提(ti)供一種新型(xing)排、取水設備(bei)。
QKSG 型潛(qian)水電泵具有兩(liang)個(ge)吸入口(kou)(kou),將兩(liang)組葉輪背靠背地對向(xiang)分布,實際上是兩(liang)臺多級泵并聯連接,各有其(qi)吸水口(kou)(kou)(一(yi)個(ge)在上部,一(yi)個(ge)在下部)。由(you)于兩(liang)組葉輪數量相(xiang)(xiang)等、方向(xiang)相(xiang)(xiang)反,其(qi)產生(sheng)的水推力大小(xiao)相(xiang)(xiang)等方向(xiang)相(xiang)(xiang)反,理論上講總軸向(xiang)水推力為零。
QKSG-D型潛水(shui)電泵(beng)(beng)只有一個吸水(shui)口,兩(liang)組葉(xie)輪(lun)(lun)也是背(bei)靠背(bei)對向(xiang)分布。當泵(beng)(beng)揚(yang)程需葉(xie)輪(lun)(lun)總級(ji)數(shu)為(wei)(wei)偶數(shu)時,每(mei)組葉(xie)輪(lun)(lun)數(shu)量相等(deng)(deng),方(fang)向(xiang)相反(fan),軸(zhou)向(xiang)水(shui)推(tui)力(li)也為(wei)(wei)零。當泵(beng)(beng)揚(yang)程需葉(xie)輪(lun)(lun)級(ji)數(shu)為(wei)(wei)奇數(shu)時,則下(xia)泵(beng)(beng)葉(xie)輪(lun)(lun)多一級(ji),此時下(xia)泵(beng)(beng)末級(ji)葉(xie)輪(lun)(lun)被(bei)設(she)計為(wei)(wei)有平衡孔的平衡葉(xie)輪(lun)(lun)。平衡葉(xie)輪(lun)(lun)產生的水(shui)推(tui)力(li),基本(ben)上(shang)被(bei)消除。于是產生軸(zhou)向(xiang)水(shui)推(tui)力(li)的兩(liang)組葉(xie)輪(lun)(lun)仍(reng)然數(shu)量相等(deng)(deng)、方(fang)向(xiang)相反(fan),總的軸(zhou)向(xiang)力(li)基本(ben)上(shang)為(wei)(wei)零。
軸向力為(wei)零,推力軸承(cheng)載(zai)荷輕,壽(shou)命(ming)長,運行可靠。是本系(xi)列潛水電(dian)泵重要技術特(te)征。
QKSG潛(qian)水電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)是充(chong)水式三(san)相異步(bu)電(dian)(dian)(dian)(dian)(dian)動機(ji)(ji),功(gong)率≥600kW時(shi),在其轉(zhuan)(zhuan)子(zi)下(xia)端(duan)設有一(yi)小泵輪,它使電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)內(nei)部充(chong)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(zhuan)(zhuan)子(zi)上(shang)帶(dai)螺旋水槽,同樣(yang)使充(chong)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(yi)般(ban))型電(dian)(dian)(dian)(dian)(dian)機(ji)(ji),動力電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)為(wei)(wei)4芯(xin)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan),其中(zhong)一(yi)芯(xin)為(wei)(wei)接地;信號電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)為(wei)(wei)8芯(xin)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan),其中(zhong)4芯(xin)為(wei)(wei)溫度,2芯(xin)為(wei)(wei)水位,2芯(xin)備(bei)用(yong)。
