一、液下渣漿泵是什么
液下渣漿泵是立式單(dan)級單(dan)吸懸臂式離(li)心泵結構,葉(xie)(xie)輪為半開式葉(xie)(xie)輪,在葉(xie)(xie)輪吸入邊延伸處(chu)設有攪拌葉(xie)(xie)片。
液下渣漿泵為(wei)單(dan)級、單(dan)吸懸臂式結構(gou),用(yong)(yong)軸(zhou)(zhou)(zhou)(zhou)承(cheng)座(zuo),支(zhi)承(cheng)座(zuo),聯(lian)接管(guan)連接泵(beng)(beng)的(de)水力(li)部(bu)件,液體由(you)出(chu)液管(guan)部(bu)件排出(chu),泵(beng)(beng)的(de)葉(xie)(xie)(xie)輪(lun)為(wei)半開式葉(xie)(xie)(xie)輪(lun),在(zai)葉(xie)(xie)(xie)輪(lun)葉(xie)(xie)(xie)片(pian)進口延伸處設(she)有攪拌葉(xie)(xie)(xie)片(pian),該(gai)泵(beng)(beng)主要(yao)特(te)點是在(zai)液下部(bu)位的(de)泵(beng)(beng)軸(zhou)(zhou)(zhou)(zhou),有足夠的(de)剛度(du),葉(xie)(xie)(xie)輪(lun),泵(beng)(beng)殼之間不(bu)設(she)軸(zhou)(zhou)(zhou)(zhou)承(cheng),不(bu)采用(yong)(yong)軸(zhou)(zhou)(zhou)(zhou)封,可(ke)以輸送(song)含有較(jiao)大(da)(da)濃度(du)固定顆粒的(de)介質。泵(beng)(beng)插入液下的(de)長度(du)在(zai)800-2000之間,如(ru)果需要(yao)可(ke)以配(pei)帶吸入管(guan)。軸(zhou)(zhou)(zhou)(zhou)封采用(yong)(yong)較(jiao)大(da)(da)泵(beng)(beng)插入液體中運行,不(bu)設(she)軸(zhou)(zhou)(zhou)(zhou)封,傳動(dong)由(you)立式電動(dong)機安(an)裝在(zai)電機支(zhi)承(cheng)和支(zhi)承(cheng)座(zuo)上,用(yong)(yong)聯(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)與(yu)泵(beng)(beng)相連。
二、液下渣漿泵的運行及監控方法有哪些
1、液(ye)下渣漿(jiang)泵(beng)(beng)(beng)啟運(yun)前(qian)應(ying)展開泵(beng)(beng)(beng)進口(kou)閥(fa),關閉(bi)泵(beng)(beng)(beng)出口(kou)閥(fa)。而后(hou)啟動(dong)泵(beng)(beng)(beng),泵(beng)(beng)(beng)啟動(dong)后(hou)再慢(man)(man)慢(man)(man)開動(dong)泵(beng)(beng)(beng)出口(kou)閥(fa),泵(beng)(beng)(beng)出口(kou)閥(fa)開大小與快慢(man)(man),應(ying)以(yi)泵(beng)(beng)(beng)不(bu)振(zhen)動(dong)和(he)電(dian)機不(bu)超額定電(dian)流來(lai)掌握。
2、串聯用泵(beng)(beng)(beng)啟(qi)動,亦(yi)遵循(xun)上述方(fang)法。開啟(qi)一級(ji)(ji)泵(beng)(beng)(beng)后,即(ji)可將末(mo)(mo)級(ji)(ji)泵(beng)(beng)(beng)出口(kou)閥(fa)門(men)找開一點(開大小(xiao)以一級(ji)(ji)泵(beng)(beng)(beng)電(dian)機電(dian)流(liu)(liu)為(wei)額定(ding)電(dian)流(liu)(liu)1/4為(wei)宜),而后即(ji)可相(xiang)繼啟(qi)動二(er)級(ji)(ji)三級(ji)(ji)直到末(mo)(mo)級(ji)(ji)泵(beng)(beng)(beng),串聯泵(beng)(beng)(beng)全(quan)部(bu)啟(qi)動后,即(ji)可逐漸開大末(mo)(mo)級(ji)(ji)泵(beng)(beng)(beng)出口(kou)閥(fa)門(men),閥(fa)門(men)開大小(xiao)快慢,應(ying)以泵(beng)(beng)(beng)不振動和(he)任一級(ji)(ji)泵(beng)(beng)(beng)電(dian)機都(dou)不超額定(ding)電(dian)流(liu)(liu)來掌(zhang)握。
3、液下渣(zha)漿泵(beng)主要(yao)以輸(shu)送流(liu)量(liang)為目,運行(xing)監控系(xi)統(tong)(tong)(tong)中(zhong)最好裝上流(liu)量(liang)表(biao)(計),以隨時監控流(liu)量(liang)是否符(fu)合要(yao)求(qiu);裝有旋流(liu)器管(guan)路(lu)系(xi)統(tong)(tong)(tong)、沖渣(zha)系(xi)統(tong)(tong)(tong)、壓(ya)濾脫水系(xi)統(tong)(tong)(tong)中(zhong)還要(yao)求(qiu)管(guan)路(lu)出口處有一定壓(ya)力(li)(li)。這種系(xi)統(tong)(tong)(tong)中(zhong)還應裝上壓(ya)力(li)(li)表(biao)以監控壓(ya)力(li)(li)是否符(fu)合要(yao)求(qiu)。
4、液(ye)下(xia)渣漿泵運行中(zhong)除監(jian)控(kong)流(liu)量(liang)、壓力外(wai),還要監(jian)控(kong)電(dian)機不要超過電(dian)機額(e)定電(dian)流(liu)。隨時(shi)監(jian)視油(you)封、軸承(cheng)等是(shi)(shi)否發生導常現(xian)象(xiang),泵是(shi)(shi)否發生抽空或溢(yi)池等,并隨時(shi)處理。
