一、產品簡介
QKSG系列潛(qian)水(shui)(shui)(shui)電(dian)泵(beng)由充水(shui)(shui)(shui)式潛(qian)水(shui)(shui)(shui)電(dian)機和多級離心(xin)(xin)泵(beng)組成,裝在吸罩內潛(qian)入水(shui)(shui)(shui)中工作(zuo)。這種潛(qian)水(shui)(shui)(shui)電(dian)泵(beng)較傳統(tong)離心(xin)(xin)泵(beng)和深(shen)井泵(beng)具(ju)有使用維護(hu)方便,運行(xing)安全(quan)可靠,性能穩(wen)定,震動噪音小,效(xiao)率高等優點(dian)(dian),改善了泵(beng)房通(tong)風(feng)散熱條件,有利環(huan)保,運行(xing)費用低,可實(shi)行(xing)自(zi)(zi)動控制,對水(shui)(shui)(shui)位落差大及有水(shui)(shui)(shui)患威脅(xie)的(de)地方更有獨特的(de)優點(dian)(dian),由于電(dian)機工作(zuo)時充滿清水(shui)(shui)(shui),在任何情況下都不(bu)會產生(sheng)電(dian)火花引爆瓦(wa)斯,屬礦用一般(ban)安全(quan)型設備。為煤(mei)炭、冶(ye)金、電(dian)力、城(cheng)建、自(zi)(zi)來水(shui)(shui)(shui)及地下水(shui)(shui)(shui)開(kai)發等部門提供(gong)一種新型排(pai)、取水(shui)(shui)(shui)設備。
QKSG 型潛水(shui)(shui)電泵具有(you)兩(liang)個(ge)(ge)吸(xi)入口,將(jiang)兩(liang)組葉輪背靠背地對向(xiang)分布,實際上(shang)是兩(liang)臺多級泵并聯連接,各有(you)其吸(xi)水(shui)(shui)口(一個(ge)(ge)在(zai)上(shang)部,一個(ge)(ge)在(zai)下(xia)部)。由于兩(liang)組葉輪數量(liang)相等(deng)、方向(xiang)相反(fan),其產生的水(shui)(shui)推力(li)大小相等(deng)方向(xiang)相反(fan),理論上(shang)講總軸向(xiang)水(shui)(shui)推力(li)為(wei)零(ling)。
QKSG-D型潛水電泵(beng)只有(you)一(yi)個吸水口,兩組葉(xie)(xie)輪(lun)(lun)也是背(bei)靠背(bei)對向(xiang)分(fen)布(bu)。當(dang)泵(beng)揚程(cheng)需葉(xie)(xie)輪(lun)(lun)總級(ji)數為(wei)(wei)偶數時,每組葉(xie)(xie)輪(lun)(lun)數量(liang)相等(deng),方向(xiang)相反,軸(zhou)向(xiang)水推(tui)(tui)力(li)也為(wei)(wei)零(ling)。當(dang)泵(beng)揚程(cheng)需葉(xie)(xie)輪(lun)(lun)級(ji)數為(wei)(wei)奇數時,則下(xia)泵(beng)葉(xie)(xie)輪(lun)(lun)多一(yi)級(ji),此時下(xia)泵(beng)末級(ji)葉(xie)(xie)輪(lun)(lun)被設計為(wei)(wei)有(you)平衡(heng)孔的(de)平衡(heng)葉(xie)(xie)輪(lun)(lun)。平衡(heng)葉(xie)(xie)輪(lun)(lun)產(chan)生的(de)水推(tui)(tui)力(li),基(ji)(ji)本(ben)上被消除。于是產(chan)生軸(zhou)向(xiang)水推(tui)(tui)力(li)的(de)兩組葉(xie)(xie)輪(lun)(lun)仍然數量(liang)相等(deng)、方向(xiang)相反,總的(de)軸(zhou)向(xiang)力(li)基(ji)(ji)本(ben)上為(wei)(wei)零(ling)。
軸(zhou)向力為(wei)零,推力軸(zhou)承載荷輕(qing),壽命長,運(yun)行可靠。是(shi)本系列潛水電泵重要技術(shu)特征。
QKSG潛水電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)是充水式(shi)三相異步(bu)電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)機(ji)(ji),功(gong)率(lv)≥600kW時(shi),在(zai)其轉子(zi)下端(duan)設(she)有(you)一(yi)小泵輪,它使(shi)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)內(nei)部充水循環以(yi)便(bian)對(dui)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)進行冷卻;功(gong)率(lv)<600kW時(shi),轉子(zi)上帶螺旋(xuan)水槽,同樣使(shi)充水循環以(yi)利電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)散熱。本(ben)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)屬KY(礦(kuang)用一(yi)般)型電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji),動(dong)力電(dian)(dian)(dian)(dian)(dian)(dian)纜為(wei)(wei)4芯(xin)(xin)電(dian)(dian)(dian)(dian)(dian)(dian)纜,其中一(yi)芯(xin)(xin)為(wei)(wei)接地(di);信號電(dian)(dian)(dian)(dian)(dian)(dian)纜為(wei)(wei)8芯(xin)(xin)電(dian)(dian)(dian)(dian)(dian)(dian)纜,其中4芯(xin)(xin)為(wei)(wei)溫(wen)度,2芯(xin)(xin)為(wei)(wei)水位(wei),2芯(xin)(xin)備用。
