一、液下渣漿泵是什么
液(ye)下渣漿泵(beng)是立式單(dan)級單(dan)吸(xi)懸臂式離(li)心泵(beng)結(jie)構,葉輪為半開(kai)式葉輪,在葉輪吸(xi)入邊延伸處(chu)設(she)有攪拌葉片。
液下渣漿泵為單(dan)級、單(dan)吸(xi)(xi)懸臂式結(jie)構,用(yong)(yong)軸(zhou)(zhou)(zhou)承(cheng)座,支承(cheng)座,聯接管(guan)(guan)連接泵(beng)的(de)(de)水力部(bu)件(jian),液(ye)體由(you)出液(ye)管(guan)(guan)部(bu)件(jian)排出,泵(beng)的(de)(de)葉輪(lun)為半開式葉輪(lun),在葉輪(lun)葉片進口(kou)延伸處設有(you)攪拌葉片,該(gai)泵(beng)主要(yao)特點是在液(ye)下(xia)部(bu)位的(de)(de)泵(beng)軸(zhou)(zhou)(zhou),有(you)足夠(gou)的(de)(de)剛(gang)度,葉輪(lun),泵(beng)殼之(zhi)(zhi)間不(bu)設軸(zhou)(zhou)(zhou)承(cheng),不(bu)采用(yong)(yong)軸(zhou)(zhou)(zhou)封,可(ke)以輸(shu)送(song)含(han)有(you)較大(da)濃度固定顆(ke)粒的(de)(de)介質(zhi)。泵(beng)插(cha)入(ru)液(ye)下(xia)的(de)(de)長度在800-2000之(zhi)(zhi)間,如(ru)果(guo)需(xu)要(yao)可(ke)以配帶吸(xi)(xi)入(ru)管(guan)(guan)。軸(zhou)(zhou)(zhou)封采用(yong)(yong)較大(da)泵(beng)插(cha)入(ru)液(ye)體中運行,不(bu)設軸(zhou)(zhou)(zhou)封,傳動(dong)由(you)立式電(dian)動(dong)機安裝(zhuang)在電(dian)機支承(cheng)和支承(cheng)座上,用(yong)(yong)聯軸(zhou)(zhou)(zhou)器與(yu)泵(beng)相連。
二、液下渣漿泵的運行及監控方法有哪些
1、液下渣漿泵(beng)(beng)啟運前應展開(kai)泵(beng)(beng)進口閥(fa),關閉泵(beng)(beng)出口閥(fa)。而(er)后啟動(dong)泵(beng)(beng),泵(beng)(beng)啟動(dong)后再慢慢開(kai)動(dong)泵(beng)(beng)出口閥(fa),泵(beng)(beng)出口閥(fa)開(kai)大(da)小與快慢,應以泵(beng)(beng)不(bu)(bu)振動(dong)和(he)電機(ji)不(bu)(bu)超額(e)定電流來掌握。
2、串聯(lian)用泵(beng)(beng)(beng)(beng)啟動(dong),亦遵循上述(shu)方法。開(kai)啟一級泵(beng)(beng)(beng)(beng)后,即可將末(mo)級泵(beng)(beng)(beng)(beng)出口閥門(men)找(zhao)開(kai)一點(dian)(開(kai)大小以一級泵(beng)(beng)(beng)(beng)電(dian)機(ji)電(dian)流為(wei)(wei)額(e)定電(dian)流1/4為(wei)(wei)宜),而后即可相繼(ji)啟動(dong)二級三級直到末(mo)級泵(beng)(beng)(beng)(beng),串聯(lian)泵(beng)(beng)(beng)(beng)全(quan)部(bu)啟動(dong)后,即可逐(zhu)漸開(kai)大末(mo)級泵(beng)(beng)(beng)(beng)出口閥門(men),閥門(men)開(kai)大小快慢,應以泵(beng)(beng)(beng)(beng)不振動(dong)和(he)任(ren)一級泵(beng)(beng)(beng)(beng)電(dian)機(ji)都不超額(e)定電(dian)流來(lai)掌(zhang)握。
3、液(ye)下渣漿(jiang)泵主要以輸(shu)送流量為目,運行監(jian)控系(xi)統(tong)中最好裝上流量表(計(ji)),以隨時監(jian)控流量是否符(fu)合(he)要求(qiu);裝有(you)旋流器(qi)管路系(xi)統(tong)、沖渣系(xi)統(tong)、壓(ya)濾脫水系(xi)統(tong)中還要求(qiu)管路出口處有(you)一定壓(ya)力(li)。這種(zhong)系(xi)統(tong)中還應裝上壓(ya)力(li)表以監(jian)控壓(ya)力(li)是否符(fu)合(he)要求(qiu)。
4、液下渣(zha)漿泵運(yun)行中除監(jian)控(kong)流(liu)量、壓力外(wai),還要(yao)監(jian)控(kong)電(dian)機不(bu)要(yao)超過電(dian)機額(e)定電(dian)流(liu)。隨時(shi)監(jian)視油封(feng)、軸承(cheng)等(deng)是(shi)否發生導常(chang)現象,泵是(shi)否發生抽空或溢(yi)池等(deng),并(bing)隨時(shi)處(chu)理。
