一、產品簡(jian)介
QKSG系列潛(qian)水(shui)(shui)(shui)電(dian)(dian)泵由充水(shui)(shui)(shui)式潛(qian)水(shui)(shui)(shui)電(dian)(dian)機(ji)和多級離心泵組成(cheng),裝在吸罩(zhao)內(nei)潛(qian)入水(shui)(shui)(shui)中(zhong)工作(zuo)。這種潛(qian)水(shui)(shui)(shui)電(dian)(dian)泵較傳統離心泵和深井泵具有(you)使用(yong)維護方便(bian),運行安(an)全可靠,性能穩(wen)定,震動噪音小,效(xiao)率(lv)高等優(you)點,改善了泵房通風散熱條件,有(you)利環保,運行費用(yong)低(di),可實行自動控(kong)制(zhi),對水(shui)(shui)(shui)位(wei)落(luo)差大及有(you)水(shui)(shui)(shui)患威脅的地(di)(di)方更有(you)獨(du)特的優(you)點,由于電(dian)(dian)機(ji)工作(zuo)時充滿清水(shui)(shui)(shui),在任何(he)情況下都不會(hui)產生電(dian)(dian)火(huo)花引爆瓦斯,屬礦用(yong)一般安(an)全型(xing)(xing)設備(bei)。為(wei)煤(mei)炭、冶金、電(dian)(dian)力、城建、自來水(shui)(shui)(shui)及地(di)(di)下水(shui)(shui)(shui)開發等部門提供一種新(xin)型(xing)(xing)排、取水(shui)(shui)(shui)設備(bei)。
QKSG 型潛(qian)水電(dian)泵具有兩(liang)(liang)(liang)個吸入口(kou),將(jiang)兩(liang)(liang)(liang)組葉輪(lun)背(bei)靠背(bei)地對向(xiang)分布(bu),實際(ji)上(shang)是兩(liang)(liang)(liang)臺多(duo)級泵并聯連接,各有其吸水口(kou)(一個在(zai)(zai)上(shang)部,一個在(zai)(zai)下部)。由于兩(liang)(liang)(liang)組葉輪(lun)數量(liang)相(xiang)(xiang)等、方向(xiang)相(xiang)(xiang)反,其產生(sheng)的水推力大小相(xiang)(xiang)等方向(xiang)相(xiang)(xiang)反,理論上(shang)講(jiang)總軸向(xiang)水推力為(wei)零(ling)。
QKSG-D型潛水電(dian)泵只有一個吸水口,兩組葉(xie)輪(lun)(lun)(lun)(lun)也是(shi)背(bei)靠(kao)背(bei)對向(xiang)分布。當泵揚程需(xu)葉(xie)輪(lun)(lun)(lun)(lun)總級(ji)數(shu)(shu)為偶數(shu)(shu)時(shi),每組葉(xie)輪(lun)(lun)(lun)(lun)數(shu)(shu)量相(xiang)等,方向(xiang)相(xiang)反,軸(zhou)向(xiang)水推力(li)(li)也為零。當泵揚程需(xu)葉(xie)輪(lun)(lun)(lun)(lun)級(ji)數(shu)(shu)為奇數(shu)(shu)時(shi),則(ze)下泵葉(xie)輪(lun)(lun)(lun)(lun)多一級(ji),此(ci)時(shi)下泵末級(ji)葉(xie)輪(lun)(lun)(lun)(lun)被設計為有平(ping)衡孔的(de)平(ping)衡葉(xie)輪(lun)(lun)(lun)(lun)。平(ping)衡葉(xie)輪(lun)(lun)(lun)(lun)產生(sheng)的(de)水推力(li)(li),基本(ben)上被消除。于是(shi)產生(sheng)軸(zhou)向(xiang)水推力(li)(li)的(de)兩組葉(xie)輪(lun)(lun)(lun)(lun)仍然數(shu)(shu)量相(xiang)等、方向(xiang)相(xiang)反,總的(de)軸(zhou)向(xiang)力(li)(li)基本(ben)上為零。
軸向力為零(ling),推力軸承載荷輕,壽命長,運行可(ke)靠。是本系列(lie)潛水電(dian)泵重要技術特征。
QKSG潛水(shui)電(dian)(dian)(dian)(dian)機(ji)(ji)是(shi)充(chong)水(shui)式三相異步電(dian)(dian)(dian)(dian)動機(ji)(ji),功率≥600kW時,在其(qi)(qi)轉(zhuan)(zhuan)子下端設有一(yi)小(xiao)泵輪,它使(shi)電(dian)(dian)(dian)(dian)機(ji)(ji)內部充(chong)水(shui)循(xun)環以便對電(dian)(dian)(dian)(dian)機(ji)(ji)進行冷卻;功率<600kW時,轉(zhuan)(zhuan)子上帶螺旋水(shui)槽,同樣使(shi)充(chong)水(shui)循(xun)環以利(li)電(dian)(dian)(dian)(dian)機(ji)(ji)散熱。本(ben)電(dian)(dian)(dian)(dian)機(ji)(ji)屬KY(礦用(yong)一(yi)般)型(xing)電(dian)(dian)(dian)(dian)機(ji)(ji),動力電(dian)(dian)(dian)(dian)纜(lan)(lan)為(wei)(wei)4芯(xin)(xin)電(dian)(dian)(dian)(dian)纜(lan)(lan),其(qi)(qi)中(zhong)一(yi)芯(xin)(xin)為(wei)(wei)接地;信號電(dian)(dian)(dian)(dian)纜(lan)(lan)為(wei)(wei)8芯(xin)(xin)電(dian)(dian)(dian)(dian)纜(lan)(lan),其(qi)(qi)中(zhong)4芯(xin)(xin)為(wei)(wei)溫度,2芯(xin)(xin)為(wei)(wei)水(shui)位,2芯(xin)(xin)備用(yong)。
