一、產品簡介
QKSG系列潛(qian)水(shui)(shui)(shui)電(dian)(dian)泵由(you)充水(shui)(shui)(shui)式潛(qian)水(shui)(shui)(shui)電(dian)(dian)機(ji)和多級離(li)心(xin)泵組成,裝在(zai)吸罩內(nei)潛(qian)入水(shui)(shui)(shui)中(zhong)工(gong)作(zuo)。這種潛(qian)水(shui)(shui)(shui)電(dian)(dian)泵較傳統(tong)離(li)心(xin)泵和深(shen)井泵具有(you)使用(yong)維護方便，運(yun)行安(an)全可靠，性能穩定，震動噪(zao)音小，效率(lv)高等(deng)優(you)(you)點，改善了泵房通風散熱條(tiao)件，有(you)利環保，運(yun)行費(fei)用(yong)低，可實行自動控制，對水(shui)(shui)(shui)位落差大及有(you)水(shui)(shui)(shui)患威(wei)脅的(de)地(di)方更(geng)有(you)獨(du)特的(de)優(you)(you)點，由(you)于電(dian)(dian)機(ji)工(gong)作(zuo)時(shi)充滿清水(shui)(shui)(shui)，在(zai)任何情況(kuang)下(xia)都不會產(chan)生(sheng)電(dian)(dian)火花(hua)引爆瓦斯(si)，屬(shu)礦用(yong)一般安(an)全型(xing)設備。為煤炭、冶金、電(dian)(dian)力、城建、自來水(shui)(shui)(shui)及地(di)下(xia)水(shui)(shui)(shui)開發等(deng)部門提供一種新型(xing)排、取水(shui)(shui)(shui)設備。
QKSG 型(xing)潛(qian)水(shui)電(dian)泵具有兩個(ge)吸入口(kou)，將兩組葉輪(lun)背靠背地對向分(fen)布，實際(ji)上(shang)(shang)是兩臺多級泵并聯連(lian)接，各有其吸水(shui)口(kou)（一個(ge)在(zai)上(shang)(shang)部，一個(ge)在(zai)下部）。由(you)于兩組葉輪(lun)數量相等(deng)、方(fang)向相反，其產生的(de)水(shui)推力大小(xiao)相等(deng)方(fang)向相反，理論上(shang)(shang)講總軸向水(shui)推力為零。
QKSG-D型潛水電泵(beng)(beng)只有(you)一個吸水口，兩(liang)組葉(xie)(xie)輪(lun)(lun)也是(shi)背靠背對向(xiang)(xiang)分布。當泵(beng)(beng)揚程需葉(xie)(xie)輪(lun)(lun)總級數(shu)為(wei)偶數(shu)時(shi)，每(mei)組葉(xie)(xie)輪(lun)(lun)數(shu)量相等(deng)，方(fang)向(xiang)(xiang)相反，軸向(xiang)(xiang)水推力也為(wei)零(ling)。當泵(beng)(beng)揚程需葉(xie)(xie)輪(lun)(lun)級數(shu)為(wei)奇數(shu)時(shi)，則下泵(beng)(beng)葉(xie)(xie)輪(lun)(lun)多一級，此時(shi)下泵(beng)(beng)末(mo)級葉(xie)(xie)輪(lun)(lun)被(bei)設計為(wei)有(you)平(ping)衡(heng)孔的(de)平(ping)衡(heng)葉(xie)(xie)輪(lun)(lun)。平(ping)衡(heng)葉(xie)(xie)輪(lun)(lun)產(chan)生的(de)水推力，基本上被(bei)消除(chu)。于是(shi)產(chan)生軸向(xiang)(xiang)水推力的(de)兩(liang)組葉(xie)(xie)輪(lun)(lun)仍然數(shu)量相等(deng)、方(fang)向(xiang)(xiang)相反，總的(de)軸向(xiang)(xiang)力基本上為(wei)零(ling)。
軸向力為零，推力軸承(cheng)載荷輕(qing)，壽命長，運行(xing)可(ke)靠。是(shi)本系列潛(qian)水電泵重(zhong)要技(ji)術特征(zheng)。
QKSG潛水(shui)(shui)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)是充(chong)水(shui)(shui)式三相異(yi)步電(dian)(dian)(dian)(dian)(dian)(dian)動機(ji)(ji)，功率≥600kW時，在其(qi)轉子(zi)下端設有(you)一小(xiao)泵(beng)輪，它使電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)內(nei)部充(chong)水(shui)(shui)循環以便對電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)進行冷卻；功率<600kW時，轉子(zi)上帶螺(luo)旋水(shui)(shui)槽，同(tong)樣使充(chong)水(shui)(shui)循環以利電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)散熱。本電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)屬(shu)KY(礦用(yong)一般(ban))型(xing)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)，動力電(dian)(dian)(dian)(dian)(dian)(dian)纜為(wei)(wei)4芯(xin)電(dian)(dian)(dian)(dian)(dian)(dian)纜，其(qi)中一芯(xin)為(wei)(wei)接地；信號電(dian)(dian)(dian)(dian)(dian)(dian)纜為(wei)(wei)8芯(xin)電(dian)(dian)(dian)(dian)(dian)(dian)纜，其(qi)中4芯(xin)為(wei)(wei)溫度，2芯(xin)為(wei)(wei)水(shui)(shui)位(wei)，2芯(xin)備用(yong)。
