蓮都機械密封利用(yong)(yong)機械方(fang)式傳(chuan)(chuan)(chuan)(chuan)遞動(dong)力(li)(li)和(he)運動(dong)的傳(chuan)(chuan)(chuan)(chuan)動(dong),機械傳(chuan)(chuan)(chuan)(chuan)動(dong)在機械工程中應用(yong)(yong)非常廣(guang)泛(fan),有(you)多種形式,主要包括(kuo)皮帶(dai)(dai)傳(chuan)(chuan)(chuan)(chuan)動(dong)、齒輪(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)、鏈(lian)傳(chuan)(chuan)(chuan)(chuan)動(dong)、蝸桿蝸輪(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)、齒輪(lun)(lun)齒條傳(chuan)(chuan)(chuan)(chuan)動(dong)和(he)螺旋傳(chuan)(chuan)(chuan)(chuan)動(dong)等(deng)。齒輪(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)能夠用(yong)(yong)于大功率的場(chang)合,傳(chuan)(chuan)(chuan)(chuan)動(dong)比準確(que),但一般要求較高的制造精度(du)和(he)安裝精度(du)。還(huan)有(you)一類是(shi)靠機件間的摩(mo)(mo)擦力(li)(li)傳(chuan)(chuan)(chuan)(chuan)遞動(dong)力(li)(li)和(he)運動(dong)的摩(mo)(mo)擦傳(chuan)(chuan)(chuan)(chuan)動(dong),包括(kuo)帶(dai)(dai)傳(chuan)(chuan)(chuan)(chuan)動(dong)、繩傳(chuan)(chuan)(chuan)(chuan)動(dong)和(he)摩(mo)(mo)擦輪(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)等(deng)。摩(mo)(mo)擦傳(chuan)(chuan)(chuan)(chuan)動(dong)容易實(shi)現(xian)無級變速,可以適應軸間距較大的傳(chuan)(chuan)(chuan)(chuan)動(dong)場(chang)合,而(er)過載打滑還(huan)能起到(dao)緩沖和(he)保(bao)護(hu)傳(chuan)(chuan)(chuan)(chuan)動(dong)裝置的作用(yong)(yong),但這(zhe)種傳(chuan)(chuan)(chuan)(chuan)動(dong)一般不(bu)能用(yong)(yong)于大功率的場(chang)合,也不(bu)能保(bao)證(zheng)準確(que)的傳(chuan)(chuan)(chuan)(chuan)動(dong)比。
傳動形式多,但是蓮都機械密封的(de)(de)(de)更換工(gong)作大同(tong)小異,首先拆前需確認電機處于檢修狀(zhuang)態,擰下加油螺(luo)塞(sai),用吸(xi)管把密封(feng)座腔內的(de)(de)(de)潤滑油吸(xi)出。準備好(hao)放(fang)置泵零(ling)件的(de)(de)(de)工(gong)作臺及拆裝工(gong)具,切勿任(ren)意亂(luan)放(fang)亂(luan)用,避(bi)免(mian)碰壞泵的(de)(de)(de)零(ling)部件。
拆對分(fen)式聯(lian)軸(zhou)器(qi)(qi)(qi):先把聯(lian)軸(zhou)器(qi)(qi)(qi)的固定(ding)內六角螺釘擰(ning)下(xia)(xia)來,再輕輕把聯(lian)軸(zhou)器(qi)(qi)(qi)的一半(ban)從(cong)軸(zhou)上慢(man)慢(man)拉下(xia)(xia),注意不要掉了,再用梅花(hua)扳手擰(ning)下(xia)(xia)泵(beng)軸(zhou)吊緊螺栓(shuan)和擋塊,讓葉輪慢(man)慢(man)下(xia)(xia)沉至泵(beng)體,然后(hou)拆下(xia)(xia)另外一半(ban)聯(lian)軸(zhou)器(qi)(qi)(qi),拿下(xia)(xia)泵(beng)軸(zhou)擋圈。
拆卸蓮都機械密封:抓住密封(feng)彈簧順著泵軸往上提(ti),就能拆下來了(le)。
拆(chai)卸(xie)并(bing)(bing)清洗(xi)軸(zhou)承(cheng)(cheng)座(zuo)(zuo):先輕(qing)輕(qing)松動一(yi)下軸(zhou)承(cheng)(cheng)座(zuo)(zuo)后用拆(chai)卸(xie)螺栓頂起(qi)軸(zhou)承(cheng)(cheng)座(zuo)(zuo),并(bing)(bing)且(qie)沿(yan)著泵軸(zhou)往(wang)上提而卸(xie)下,再(zai)用噴氣燃(ran)料清洗(xi)軸(zhou)承(cheng)(cheng)及座(zuo)(zuo),裝前晾干并(bing)(bing)涂抹少許(xu)20號機械油用來潤滑(hua)保護。
拆密(mi)封(feng)座(zuo):擰下密(mi)封(feng)座(zuo)壓(ya)緊螺母,輕輕卸下密(mi)封(feng)座(zuo)并清洗。
蓮都機械密封裝(zhuang)配(pei):在動、靜環鏡面上(shang)涂一層潔凈的20號(hao)潤(run)滑油(you),導軸承座也抹(mo)上(shang)潤(run)滑油(you),先把(ba)靜環輕(qing)(qing)(qing)輕(qing)(qing)(qing)定位裝(zhuang)入導軸承座,再在泵軸上(shang)抹(mo)上(shang)潤(run)滑油(you),把(ba)動環部分輕(qing)(qing)(qing)輕(qing)(qing)(qing)裝(zhuang)入泵軸上(shang),用手輕(qing)(qing)(qing)推密(mi)封環應能伸縮(suo)自如,注意(yi)動、靜環部分的防轉部位需裝(zhuang)配(pei)到(dao)位。
裝(zhuang)(zhuang)(zhuang)(zhuang)聯(lian)(lian)軸(zhou)(zhou)器(qi):在電機軸(zhou)(zhou)頭上裝(zhuang)(zhuang)(zhuang)(zhuang)上擋(dang)圈,裝(zhuang)(zhuang)(zhuang)(zhuang)上一(yi)半聯(lian)(lian)軸(zhou)(zhou)器(qi),再(zai)在泵軸(zhou)(zhou)端和聯(lian)(lian)軸(zhou)(zhou)器(qi)槽內(nei)裝(zhuang)(zhuang)(zhuang)(zhuang)上擋(dang)塊并用(yong)梅花扳手(shou)擰(ning)緊螺栓(shuan);再(zai)裝(zhuang)(zhuang)(zhuang)(zhuang)上另一(yi)半聯(lian)(lian)軸(zhou)(zhou)器(qi)擰(ning)上內(nei)六角螺釘。安裝(zhuang)(zhuang)(zhuang)(zhuang)聯(lian)(lian)軸(zhou)(zhou)器(qi)正確的檢查(cha)要求:對分式聯(lian)(lian)軸(zhou)(zhou)器(qi)上下(xia)間(jian)隙需要均勻,用(yong)手(shou)盤動聯(lian)(lian)軸(zhou)(zhou)器(qi)幾圈檢查(cha)轉動的靈活性。
裝密(mi)封座:先(xian)將(jiang)密(mi)封座裝入橡膠油封,再把密(mi)封座裝入泵蓋(gai)并壓在(zai)軸(zhou)承座上,擰緊(jin)(jin)螺(luo)母,確保所有安裝螺(luo)釘緊(jin)(jin)固。當安裝螺(luo)釘被用(yong)作密(mi)封與軸(zhou)之間(jian)的(de)驅動(dong)時,軸(zhou)應打埋頭孔來加固連(lian)接(jie),緊(jin)(jin)固壓蓋(gai)螺(luo)栓(shuan)時應該平穩緊(jin)(jin)固,并且不(bu)(bu)要使壓蓋(gai)受彈力。在(zai)可能的(de)地方(fang)使用(yong)4個以(yi)上螺(luo)釘的(de)等間(jian)距壓蓋(gai),緊(jin)(jin)固壓蓋(gai)螺(luo)栓(shuan)時,用(yong)塞尺檢查軸(zhou)與壓蓋(gai)之間(jian)的(de)間(jian)隙,這在(zai)密(mi)封腔(qiang)對壓蓋(gai)不(bu)(bu)導向時,顯(xian)得(de)特(te)別重(zhong)要,因(yin)為壓蓋(gai)必須(xu)對中(zhong)。
