稱多機械密封利用機(ji)(ji)械(xie)(xie)方式傳(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)力(li)和(he)(he)運動(dong)(dong)(dong)(dong)的(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong),機(ji)(ji)械(xie)(xie)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)在機(ji)(ji)械(xie)(xie)工程中應用非(fei)常(chang)廣泛,有多(duo)種形(xing)式,主要包(bao)括皮(pi)帶傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、蝸桿蝸輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒(chi)輪(lun)齒(chi)條傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)(he)螺旋傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)等。齒(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)能夠用于(yu)大功(gong)(gong)率的(de)場(chang)(chang)合,傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)比準確,但一(yi)般要求較高的(de)制造精度(du)和(he)(he)安(an)裝(zhuang)精度(du)。還有一(yi)類是靠機(ji)(ji)件間的(de)摩擦(ca)(ca)(ca)力(li)傳(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)力(li)和(he)(he)運動(dong)(dong)(dong)(dong)的(de)摩擦(ca)(ca)(ca)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong),包(bao)括帶傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)(he)摩擦(ca)(ca)(ca)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)等。摩擦(ca)(ca)(ca)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)容易(yi)實現(xian)無級變速,可以(yi)適(shi)應軸(zhou)間距較大的(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)場(chang)(chang)合,而過載打滑還能起(qi)到緩(huan)沖(chong)和(he)(he)保護傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)裝(zhuang)置的(de)作用,但這種傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)一(yi)般不能用于(yu)大功(gong)(gong)率的(de)場(chang)(chang)合,也不能保證(zheng)準確的(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)比。
傳動形式多,但是稱多機械密封的更換工作(zuo)大(da)同小異,首先(xian)拆前需(xu)確認電機處于檢修狀態,擰下加油(you)螺塞,用吸管把(ba)密封座腔內(nei)的潤(run)滑油(you)吸出(chu)。準備好放置泵(beng)(beng)零件的工作(zuo)臺及(ji)拆裝工具,切勿任意亂放亂用,避免碰壞泵(beng)(beng)的零部件。
拆(chai)(chai)對分式聯(lian)軸(zhou)(zhou)(zhou)器(qi):先(xian)把(ba)聯(lian)軸(zhou)(zhou)(zhou)器(qi)的固定內六角螺釘擰(ning)(ning)下(xia)(xia)(xia)來,再輕(qing)輕(qing)把(ba)聯(lian)軸(zhou)(zhou)(zhou)器(qi)的一半從軸(zhou)(zhou)(zhou)上慢慢拉下(xia)(xia)(xia),注意不要掉了,再用梅(mei)花(hua)扳(ban)手(shou)擰(ning)(ning)下(xia)(xia)(xia)泵(beng)軸(zhou)(zhou)(zhou)吊緊螺栓(shuan)和擋塊,讓葉(xie)輪慢慢下(xia)(xia)(xia)沉至(zhi)泵(beng)體,然后(hou)拆(chai)(chai)下(xia)(xia)(xia)另外一半聯(lian)軸(zhou)(zhou)(zhou)器(qi),拿下(xia)(xia)(xia)泵(beng)軸(zhou)(zhou)(zhou)擋圈。
拆卸稱多機械密封:抓住密封彈簧順(shun)著泵(beng)軸往上提,就能拆下來了。
拆卸并清洗軸(zhou)(zhou)(zhou)承(cheng)座:先(xian)輕輕松動一下(xia)軸(zhou)(zhou)(zhou)承(cheng)座后用拆卸螺栓頂(ding)起(qi)軸(zhou)(zhou)(zhou)承(cheng)座,并且(qie)沿著泵軸(zhou)(zhou)(zhou)往上提而卸下(xia),再(zai)用噴(pen)氣燃(ran)料清洗軸(zhou)(zhou)(zhou)承(cheng)及(ji)座,裝前(qian)晾(liang)干并涂抹(mo)少許20號機械(xie)油用來(lai)潤滑(hua)保(bao)護。
拆密封座(zuo):擰下(xia)密封座(zuo)壓(ya)緊螺母(mu),輕(qing)輕(qing)卸下(xia)密封座(zuo)并清(qing)洗。
稱多機械密封裝配:在動、靜(jing)(jing)環(huan)鏡(jing)面上涂一層潔凈(jing)的(de)20號潤滑油,導(dao)軸承座(zuo)也抹上潤滑油,先把(ba)靜(jing)(jing)環(huan)輕(qing)(qing)(qing)輕(qing)(qing)(qing)定位(wei)裝入導(dao)軸承座(zuo),再在泵軸上抹上潤滑油,把(ba)動環(huan)部(bu)分(fen)輕(qing)(qing)(qing)輕(qing)(qing)(qing)裝入泵軸上,用手輕(qing)(qing)(qing)推密封環(huan)應能(neng)伸縮(suo)自如,注(zhu)意(yi)動、靜(jing)(jing)環(huan)部(bu)分(fen)的(de)防轉部(bu)位(wei)需裝配到(dao)位(wei)。
裝(zhuang)聯(lian)軸(zhou)器:在(zai)電機(ji)軸(zhou)頭(tou)上(shang)(shang)裝(zhuang)上(shang)(shang)擋(dang)圈,裝(zhuang)上(shang)(shang)一半(ban)聯(lian)軸(zhou)器,再在(zai)泵軸(zhou)端和聯(lian)軸(zhou)器槽內(nei)裝(zhuang)上(shang)(shang)擋(dang)塊并用梅花扳手(shou)擰緊螺栓(shuan);再裝(zhuang)上(shang)(shang)另一半(ban)聯(lian)軸(zhou)器擰上(shang)(shang)內(nei)六角螺釘。安(an)裝(zhuang)聯(lian)軸(zhou)器正確的檢查(cha)要(yao)(yao)求:對分(fen)式聯(lian)軸(zhou)器上(shang)(shang)下間隙需要(yao)(yao)均勻,用手(shou)盤動聯(lian)軸(zhou)器幾圈檢查(cha)轉動的靈活性。
裝(zhuang)(zhuang)密(mi)封(feng)(feng)座(zuo):先將密(mi)封(feng)(feng)座(zuo)裝(zhuang)(zhuang)入(ru)橡(xiang)膠油封(feng)(feng),再把密(mi)封(feng)(feng)座(zuo)裝(zhuang)(zhuang)入(ru)泵(beng)蓋(gai)(gai)(gai)并壓(ya)(ya)在軸(zhou)承座(zuo)上(shang),擰緊螺(luo)母,確保所有安(an)裝(zhuang)(zhuang)螺(luo)釘緊固(gu)(gu)。當安(an)裝(zhuang)(zhuang)螺(luo)釘被用作密(mi)封(feng)(feng)與軸(zhou)之(zhi)間(jian)的(de)驅動時(shi)(shi),軸(zhou)應打埋頭孔(kong)來加固(gu)(gu)連接,緊固(gu)(gu)壓(ya)(ya)蓋(gai)(gai)(gai)螺(luo)栓時(shi)(shi)應該平穩緊固(gu)(gu),并且不要使壓(ya)(ya)蓋(gai)(gai)(gai)受彈(dan)力。在可能的(de)地方(fang)使用4個(ge)以上(shang)螺(luo)釘的(de)等間(jian)距(ju)壓(ya)(ya)蓋(gai)(gai)(gai),緊固(gu)(gu)壓(ya)(ya)蓋(gai)(gai)(gai)螺(luo)栓時(shi)(shi),用塞尺檢查軸(zhou)與壓(ya)(ya)蓋(gai)(gai)(gai)之(zhi)間(jian)的(de)間(jian)隙,這在密(mi)封(feng)(feng)腔對壓(ya)(ya)蓋(gai)(gai)(gai)不導向時(shi)(shi),顯得(de)特別重(zhong)要,因為壓(ya)(ya)蓋(gai)(gai)(gai)必須對中。
