萬榮機械密封利用機(ji)(ji)械(xie)方(fang)式傳(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)力(li)和運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)的傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong),機(ji)(ji)械(xie)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)在機(ji)(ji)械(xie)工程(cheng)中應用非常廣泛,有多種形式,主要包(bao)括皮(pi)帶(dai)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、齒輪(lun)(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、蝸(gua)(gua)桿蝸(gua)(gua)輪(lun)(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、齒輪(lun)(lun)齒條傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)和螺旋(xuan)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)等(deng)。齒輪(lun)(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)能(neng)夠用于(yu)大功率的場合,傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)比準確(que),但一般要求較(jiao)高的制造精度和安裝精度。還有一類是靠機(ji)(ji)件(jian)間的摩(mo)(mo)擦(ca)力(li)傳(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)力(li)和運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)的摩(mo)(mo)擦(ca)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong),包(bao)括帶(dai)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)和摩(mo)(mo)擦(ca)輪(lun)(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)等(deng)。摩(mo)(mo)擦(ca)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)容易實現無級變速,可以適應軸間距較(jiao)大的傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)場合,而(er)過載打滑還能(neng)起到緩(huan)沖(chong)和保(bao)護(hu)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)裝置的作用,但這(zhe)種傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)一般不能(neng)用于(yu)大功率的場合,也不能(neng)保(bao)證準確(que)的傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)比。
傳動形式多,但是萬榮機械密封的(de)更換(huan)工作(zuo)大同小異(yi),首先拆前需確認電(dian)機處于(yu)檢修狀態(tai),擰下加油螺塞,用(yong)吸管把密封座腔內的(de)潤滑油吸出。準備好放置(zhi)泵零件的(de)工作(zuo)臺(tai)及拆裝工具(ju),切勿任意亂放亂用(yong),避免(mian)碰壞泵的(de)零部件。
拆對分式聯軸(zhou)(zhou)器(qi)(qi)(qi):先把(ba)聯軸(zhou)(zhou)器(qi)(qi)(qi)的固定內六角螺釘擰下(xia)來,再輕輕把(ba)聯軸(zhou)(zhou)器(qi)(qi)(qi)的一半(ban)從(cong)軸(zhou)(zhou)上慢(man)慢(man)拉(la)下(xia),注意不要掉(diao)了(le),再用梅花扳手擰下(xia)泵軸(zhou)(zhou)吊緊螺栓和擋塊,讓葉輪慢(man)慢(man)下(xia)沉(chen)至泵體(ti),然后(hou)拆下(xia)另外一半(ban)聯軸(zhou)(zhou)器(qi)(qi)(qi),拿下(xia)泵軸(zhou)(zhou)擋圈(quan)。
拆卸萬榮機械密封:抓住(zhu)密封彈簧(huang)順著泵軸往上提(ti),就(jiu)能(neng)拆(chai)下來了。
拆卸并(bing)清(qing)(qing)洗(xi)軸(zhou)(zhou)承座(zuo):先輕(qing)輕(qing)松(song)動一下軸(zhou)(zhou)承座(zuo)后(hou)用拆卸螺(luo)栓頂起(qi)軸(zhou)(zhou)承座(zuo),并(bing)且(qie)沿(yan)著(zhu)泵(beng)軸(zhou)(zhou)往上提而卸下,再用噴氣燃料清(qing)(qing)洗(xi)軸(zhou)(zhou)承及座(zuo),裝前晾干(gan)并(bing)涂(tu)抹少許20號機械油用來潤(run)滑(hua)保護。
拆密(mi)封(feng)座(zuo):擰下密(mi)封(feng)座(zuo)壓緊螺母,輕(qing)輕(qing)卸下密(mi)封(feng)座(zuo)并清洗。
萬榮機械密封裝配(pei):在動(dong)、靜(jing)(jing)環(huan)鏡面上涂(tu)一層潔凈的20號潤滑油(you)(you),導軸承(cheng)座也抹上潤滑油(you)(you),先把靜(jing)(jing)環(huan)輕輕定位裝入(ru)導軸承(cheng)座,再在泵軸上抹上潤滑油(you)(you),把動(dong)環(huan)部分輕輕裝入(ru)泵軸上,用手輕推密封環(huan)應能伸(shen)縮自(zi)如,注意動(dong)、靜(jing)(jing)環(huan)部分的防(fang)轉部位需(xu)裝配(pei)到(dao)位。
裝(zhuang)聯(lian)(lian)軸(zhou)器(qi):在電機軸(zhou)頭上(shang)裝(zhuang)上(shang)擋圈,裝(zhuang)上(shang)一半(ban)聯(lian)(lian)軸(zhou)器(qi),再在泵軸(zhou)端和聯(lian)(lian)軸(zhou)器(qi)槽內(nei)裝(zhuang)上(shang)擋塊并用梅(mei)花扳手擰緊螺栓;再裝(zhuang)上(shang)另(ling)一半(ban)聯(lian)(lian)軸(zhou)器(qi)擰上(shang)內(nei)六(liu)角螺釘。安裝(zhuang)聯(lian)(lian)軸(zhou)器(qi)正確的檢查要求(qiu):對分式聯(lian)(lian)軸(zhou)器(qi)上(shang)下(xia)間隙需要均勻(yun),用手盤動聯(lian)(lian)軸(zhou)器(qi)幾圈檢查轉動的靈活性。
裝(zhuang)密封(feng)座(zuo)(zuo):先將(jiang)密封(feng)座(zuo)(zuo)裝(zhuang)入橡膠油封(feng),再把(ba)密封(feng)座(zuo)(zuo)裝(zhuang)入泵蓋(gai)并壓(ya)(ya)(ya)在(zai)軸(zhou)(zhou)承座(zuo)(zuo)上,擰緊(jin)(jin)(jin)螺母,確(que)保所有安裝(zhuang)螺釘(ding)緊(jin)(jin)(jin)固(gu)(gu)。當安裝(zhuang)螺釘(ding)被用作密封(feng)與(yu)軸(zhou)(zhou)之(zhi)(zhi)間的驅動(dong)時,軸(zhou)(zhou)應打埋頭(tou)孔來加固(gu)(gu)連接,緊(jin)(jin)(jin)固(gu)(gu)壓(ya)(ya)(ya)蓋(gai)螺栓時應該平(ping)穩(wen)緊(jin)(jin)(jin)固(gu)(gu),并且不要使(shi)壓(ya)(ya)(ya)蓋(gai)受彈(dan)力。在(zai)可能(neng)的地方使(shi)用4個以上螺釘(ding)的等(deng)間距壓(ya)(ya)(ya)蓋(gai),緊(jin)(jin)(jin)固(gu)(gu)壓(ya)(ya)(ya)蓋(gai)螺栓時,用塞尺檢查軸(zhou)(zhou)與(yu)壓(ya)(ya)(ya)蓋(gai)之(zhi)(zhi)間的間隙,這在(zai)密封(feng)腔對壓(ya)(ya)(ya)蓋(gai)不導向時,顯(xian)得(de)特別(bie)重要,因為壓(ya)(ya)(ya)蓋(gai)必須對中。
