雙塔機械密封利用(yong)(yong)機械(xie)(xie)方式傳(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)力(li)和(he)(he)運(yun)(yun)動(dong)(dong)(dong)的(de)(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong),機械(xie)(xie)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)在(zai)機械(xie)(xie)工程中(zhong)應用(yong)(yong)非常廣(guang)泛,有(you)多種形式,主(zhu)要(yao)(yao)包括皮帶(dai)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、齒(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、蝸(gua)桿蝸(gua)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、齒(chi)輪(lun)齒(chi)條傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)和(he)(he)螺旋傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)等。齒(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)能(neng)夠用(yong)(yong)于(yu)(yu)大(da)功率的(de)(de)場合(he)(he),傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)比準確,但一(yi)般要(yao)(yao)求較高的(de)(de)制造精(jing)度和(he)(he)安裝精(jing)度。還有(you)一(yi)類是靠機件間(jian)的(de)(de)摩擦力(li)傳(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)力(li)和(he)(he)運(yun)(yun)動(dong)(dong)(dong)的(de)(de)摩擦傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong),包括帶(dai)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)和(he)(he)摩擦輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)等。摩擦傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)容易實現(xian)無級(ji)變速,可以適應軸間(jian)距(ju)較大(da)的(de)(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)場合(he)(he),而(er)過載打滑還能(neng)起到緩沖(chong)和(he)(he)保(bao)護傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)裝置的(de)(de)作用(yong)(yong),但這種傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)一(yi)般不能(neng)用(yong)(yong)于(yu)(yu)大(da)功率的(de)(de)場合(he)(he),也不能(neng)保(bao)證(zheng)準確的(de)(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)比。
傳動形式多,但是雙塔機械密封的更換工(gong)(gong)作(zuo)大同(tong)小異,首先拆前需確認電(dian)機(ji)處(chu)于檢修狀(zhuang)態,擰下加油螺塞(sai),用吸(xi)管把密封座腔內的潤(run)滑油吸(xi)出。準備好放置泵零件(jian)的工(gong)(gong)作(zuo)臺(tai)及(ji)拆裝工(gong)(gong)具,切勿任意(yi)亂放亂用,避免碰壞泵的零部(bu)件(jian)。
拆對分式(shi)聯軸(zhou)(zhou)器(qi):先把聯軸(zhou)(zhou)器(qi)的(de)(de)固定內六角螺(luo)(luo)釘擰下來(lai),再輕輕把聯軸(zhou)(zhou)器(qi)的(de)(de)一半(ban)從(cong)軸(zhou)(zhou)上(shang)慢(man)(man)慢(man)(man)拉下,注意不要掉了(le),再用梅花扳手(shou)擰下泵軸(zhou)(zhou)吊緊螺(luo)(luo)栓和擋塊,讓葉輪慢(man)(man)慢(man)(man)下沉(chen)至泵體,然后拆下另外(wai)一半(ban)聯軸(zhou)(zhou)器(qi),拿下泵軸(zhou)(zhou)擋圈(quan)。
拆卸雙塔機械密封:抓住(zhu)密封彈(dan)簧順著(zhu)泵(beng)軸往(wang)上提,就能拆下來了。
拆(chai)卸并清(qing)洗軸承座(zuo)(zuo):先輕輕松動一下(xia)軸承座(zuo)(zuo)后用拆(chai)卸螺(luo)栓頂起軸承座(zuo)(zuo),并且沿著泵(beng)軸往上(shang)提(ti)而卸下(xia),再用噴氣燃料(liao)清(qing)洗軸承及座(zuo)(zuo),裝(zhuang)前晾干并涂抹(mo)少(shao)許(xu)20號機械油(you)用來潤滑保(bao)護。
拆密(mi)(mi)封(feng)座:擰(ning)下密(mi)(mi)封(feng)座壓(ya)緊螺(luo)母(mu),輕輕卸(xie)下密(mi)(mi)封(feng)座并(bing)清洗(xi)。
雙塔機械密封裝(zhuang)(zhuang)配(pei):在動、靜(jing)環(huan)(huan)鏡面上(shang)涂一層潔凈的20號潤滑(hua)油(you),導(dao)軸(zhou)承(cheng)座也抹(mo)(mo)上(shang)潤滑(hua)油(you),先把靜(jing)環(huan)(huan)輕(qing)輕(qing)定位裝(zhuang)(zhuang)入導(dao)軸(zhou)承(cheng)座,再在泵軸(zhou)上(shang)抹(mo)(mo)上(shang)潤滑(hua)油(you),把動環(huan)(huan)部分輕(qing)輕(qing)裝(zhuang)(zhuang)入泵軸(zhou)上(shang),用手輕(qing)推密封環(huan)(huan)應能伸縮(suo)自如,注意動、靜(jing)環(huan)(huan)部分的防轉部位需裝(zhuang)(zhuang)配(pei)到位。
裝(zhuang)聯(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi):在電機(ji)軸(zhou)(zhou)(zhou)(zhou)(zhou)頭(tou)上(shang)裝(zhuang)上(shang)擋圈(quan),裝(zhuang)上(shang)一半聯(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi),再在泵軸(zhou)(zhou)(zhou)(zhou)(zhou)端和聯(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)槽(cao)內裝(zhuang)上(shang)擋塊并用梅花扳手(shou)(shou)擰(ning)緊螺栓(shuan);再裝(zhuang)上(shang)另一半聯(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)擰(ning)上(shang)內六(liu)角螺釘。安裝(zhuang)聯(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)正確的檢查要(yao)(yao)求:對分式聯(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)上(shang)下間隙(xi)需要(yao)(yao)均勻,用手(shou)(shou)盤動聯(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)幾圈(quan)檢查轉動的靈活性。
裝(zhuang)密封(feng)座(zuo):先(xian)將密封(feng)座(zuo)裝(zhuang)入(ru)橡膠油封(feng),再(zai)把密封(feng)座(zuo)裝(zhuang)入(ru)泵蓋(gai)(gai)(gai)并壓(ya)(ya)(ya)在(zai)軸(zhou)承座(zuo)上(shang),擰(ning)緊螺母(mu),確保所有安裝(zhuang)螺釘(ding)緊固(gu)(gu)。當(dang)安裝(zhuang)螺釘(ding)被用作(zuo)密封(feng)與軸(zhou)之(zhi)(zhi)間的驅動時(shi)(shi),軸(zhou)應打(da)埋頭孔來加固(gu)(gu)連(lian)接,緊固(gu)(gu)壓(ya)(ya)(ya)蓋(gai)(gai)(gai)螺栓(shuan)(shuan)時(shi)(shi)應該平(ping)穩緊固(gu)(gu),并且不要使壓(ya)(ya)(ya)蓋(gai)(gai)(gai)受彈力。在(zai)可能的地方使用4個以上(shang)螺釘(ding)的等間距壓(ya)(ya)(ya)蓋(gai)(gai)(gai),緊固(gu)(gu)壓(ya)(ya)(ya)蓋(gai)(gai)(gai)螺栓(shuan)(shuan)時(shi)(shi),用塞尺(chi)檢查軸(zhou)與壓(ya)(ya)(ya)蓋(gai)(gai)(gai)之(zhi)(zhi)間的間隙,這在(zai)密封(feng)腔對壓(ya)(ya)(ya)蓋(gai)(gai)(gai)不導向時(shi)(shi),顯得特別(bie)重(zhong)要,因為壓(ya)(ya)(ya)蓋(gai)(gai)(gai)必須對中。
