渣漿陵水泵用陵水機械密封主(zhu)要用(yong)(yong)(yong)于燃煤發電煙氣渣漿裝置中和漿液(ye)循環泵上(shang),也可(ke)以(yi)用(yong)(yong)(yong)于化工(gong)、造紙等行業的(de)行業。在渣漿的(de)工(gong)藝流程中,有(you)(you)的(de)工(gong)位的(de)泵輸(shu)(shu)送(song)的(de)介質(zhi)含有(you)(you)顆粒,有(you)(you)的(de)輸(shu)(shu)送(song)介質(zhi)較干凈(jing),在選(xuan)擇密(mi)封時是有(you)(you)差別的(de)。對有(you)(you)顆粒的(de),泵一般(ban)要求配用(yong)(yong)(yong)雙端面(mian),背對背密(mi)封形式,可(ke)以(yi)有(you)(you)效阻止顆粒進入密(mi)封端面(mian),保證(zheng)密(mi)封的(de)使用(yong)(yong)(yong)壽(shou)命。
想要渣漿陵水泵用陵水機械密封在使用(yong)中(zhong)減(jian)少(shao)故障次(ci)數,首先要選型(xing)正確,然后要掌握安裝和使用(yong)的要領。
為適應(ying)不(bu)同(tong)(tong)(tong)的(de)(de)(de)渣漿(jiang)(jiang)特性,會(hui)設(she)(she)計(ji)不(bu)同(tong)(tong)(tong)類型的(de)(de)(de)離心(xin)式渣漿(jiang)(jiang)泵(beng)(beng)(beng)。對輕(qing)磨(mo)蝕(shi)渣漿(jiang)(jiang),應(ying)該(gai)選用(yong)(yong)(yong)(yong)輕(qing)磨(mo)蝕(shi)渣漿(jiang)(jiang)泵(beng)(beng)(beng),以(yi)降(jiang)低(di)(di)(di)成(cheng)本,延長(chang)泵(beng)(beng)(beng)的(de)(de)(de)使(shi)(shi)用(yong)(yong)(yong)(yong)壽(shou)命(ming)(ming);對重(zhong)磨(mo)蝕(shi)渣漿(jiang)(jiang)應(ying)該(gai)選用(yong)(yong)(yong)(yong)重(zhong)磨(mo)蝕(shi)渣漿(jiang)(jiang)泵(beng)(beng)(beng)。具體選型時可參閱廠(chang)家設(she)(she)計(ji)參考(kao)資(zi)料(liao)(liao)。由(you)于(yu)(yu)不(bu)同(tong)(tong)(tong)的(de)(de)(de)渣漿(jiang)(jiang)特性有(you)不(bu)同(tong)(tong)(tong)的(de)(de)(de)耐磨(mo)材料(liao)(liao)相對應(ying),因此(ci)設(she)(she)計(ji)中(zhong)應(ying)該(gai)根據不(bu)同(tong)(tong)(tong)的(de)(de)(de)渣漿(jiang)(jiang)特性按(an)照廠(chang)家提供的(de)(de)(de)資(zi)料(liao)(liao)選擇(ze)不(bu)同(tong)(tong)(tong)的(de)(de)(de)耐磨(mo)材料(liao)(liao),以(yi)低(di)(di)(di)成(cheng)本取(qu)得(de)更長(chang)的(de)(de)(de)使(shi)(shi)用(yong)(yong)(yong)(yong)壽(shou)命(ming)(ming)。由(you)于(yu)(yu)降(jiang)低(di)(di)(di)泵(beng)(beng)(beng)的(de)(de)(de)轉速和流(liu)量有(you)利于(yu)(yu)提高泵(beng)(beng)(beng)的(de)(de)(de)使(shi)(shi)用(yong)(yong)(yong)(yong)壽(shou)命(ming)(ming)。使(shi)(shi)用(yong)(yong)(yong)(yong)用(yong)(yong)(yong)(yong)于(yu)(yu)輸送(song)輕(qing)磨(mo)蝕(shi)渣漿(jiang)(jiang)的(de)(de)(de)高揚(yang)(yang)程(cheng)渣漿(jiang)(jiang)泵(beng)(beng)(beng)輸送(song)重(zhong)磨(mo)蝕(shi)渣漿(jiang)(jiang),有(you)時可延長(chang)壽(shou)命(ming)(ming),降(jiang)低(di)(di)(di)成(cheng)本。這是(shi)由(you)于(yu)(yu)高揚(yang)(yang)程(cheng)泵(beng)(beng)(beng)在低(di)(di)(di)轉速時揚(yang)(yang)程(cheng)就較(jiao)(jiao)高,而且效率比(bi)較(jiao)(jiao)均衡。如果設(she)(she)計(ji)流(liu)量再小的(de)(de)(de)話,由(you)于(yu)(yu)轉速極低(di)(di)(di),會(hui)使(shi)(shi)該(gai)泵(beng)(beng)(beng)在低(di)(di)(di)成(cheng)本下的(de)(de)(de)使(shi)(shi)用(yong)(yong)(yong)(yong)壽(shou)命(ming)(ming)高于(yu)(yu)使(shi)(shi)用(yong)(yong)(yong)(yong)重(zhong)磨(mo)蝕(shi)渣漿(jiang)(jiang)泵(beng)(beng)(beng)的(de)(de)(de)使(shi)(shi)用(yong)(yong)(yong)(yong)壽(shou)命(ming)(ming)。
在(zai)泵(beng)(beng)的(de)(de)選型設(she)計中(zhong)還應該準確(que)計算泵(beng)(beng)的(de)(de)揚(yang)程,否則泵(beng)(beng)的(de)(de)揚(yang)程過(guo)(guo)高(gao)會(hui)(hui)導致(zhi)泵(beng)(beng)的(de)(de)流量(liang)過(guo)(guo)大,產生(sheng)抽空現象(xiang),會(hui)(hui)夾帶進空氣導致(zhi)泵(beng)(beng)的(de)(de)損(sun)壞(huai),同(tong)時(shi)流量(liang)加大也會(hui)(hui)使泵(beng)(beng)內的(de)(de)礦漿流速過(guo)(guo)高(gao),降低泵(beng)(beng)的(de)(de)使用壽(shou)命(ming)。此(ci)外在(zai)渣漿泵(beng)(beng)選型中(zhong),選擇合(he)適(shi)廠家的(de)(de)渣漿泵(beng)(beng),確(que)保渣漿泵(beng)(beng)的(de)(de)高(gao)質量(liang),也是很重(zhong)要的(de)(de)內容。
渣漿陵水泵用陵水機械密封安裝、使用小技巧:
1、安裝(zhuang)時(shi)在與(yu)密封相接(jie)觸的表面(mian)應涂一層清潔(jie)的潤滑(hua)劑(ji)(ji),以(yi)便能順利(li)裝(zhuang)配。推薦(jian)使用潤滑(hua)劑(ji)(ji):肥皂水(shui)、硅潤滑(hua)脂、乙二(er)酯(zhi)或甘油(you)等(deng)。
2、設(she)備的密封(feng)腔部位在(zai)安裝(zhuang)時應保持(chi)清潔,密封(feng)零件應進行清洗,保持(chi)密封(feng)端面完(wan)好無損,防止(zhi)雜質和灰塵帶入密封(feng)部位;
3、在安裝過程中嚴禁敲打和碰擊,以免使陵水機械密封付破損而造成(cheng)密(mi)封失效(xiao);
4、對易結晶、顆粒介質,對介質溫度>80℃時,應采取相應的沖洗、過濾、冷卻措施,各種輔助裝置請參照陵水機械密封有關標準;
5、安裝靜(jing)環(huan)壓蓋時,擰緊(jin)螺絲(si)必(bi)須(xu)受力均勻,保證靜(jing)環(huan)端(duan)面與軸垂直求;
6、安裝后(hou)用手推(tui)動(dong)動(dong)環,能使動(dong)環在軸(zhou)上靈活(huo)移動(dong),并有一定彈性;
7、安裝后用手(shou)盤動(dong)轉軸(zhou)、轉軸(zhou)應無輕重感覺;
8、設備在運轉前必(bi)須充滿介質,以防(fang)止干摩擦(ca)而(er)使密封失(shi)效(xiao)。
