合作機械密封利用(yong)機械(xie)方(fang)式傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)力和(he)運(yun)動(dong)(dong)(dong)(dong)(dong)的(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong),機械(xie)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)在機械(xie)工(gong)程中應用(yong)非(fei)常廣泛,有多種形式,主要包括皮帶(dai)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)輪傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、蝸(gua)桿蝸(gua)輪傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)輪齒(chi)條傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)螺旋(xuan)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等。齒(chi)輪傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)能夠用(yong)于大(da)功率(lv)的(de)場(chang)合(he),傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比準確,但一(yi)般要求較高的(de)制造精度和(he)安(an)裝精度。還有一(yi)類(lei)是(shi)靠機件間的(de)摩擦(ca)力傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)力和(he)運(yun)動(dong)(dong)(dong)(dong)(dong)的(de)摩擦(ca)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong),包括帶(dai)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)摩擦(ca)輪傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等。摩擦(ca)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)容易實(shi)現無級變速,可以適應軸(zhou)間距較大(da)的(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)場(chang)合(he),而過載打滑還能起(qi)到緩(huan)沖和(he)保(bao)護(hu)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)裝置的(de)作(zuo)用(yong),但這種傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)一(yi)般不能用(yong)于大(da)功率(lv)的(de)場(chang)合(he),也不能保(bao)證準確的(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比。
傳動形式多,但是合作機械密封的(de)(de)更換工(gong)作(zuo)大同小異,首先(xian)拆前需確認電(dian)機處于檢修狀(zhuang)態,擰下加油螺塞,用吸(xi)(xi)管把密封(feng)座腔內的(de)(de)潤(run)滑(hua)油吸(xi)(xi)出。準備好(hao)放置(zhi)泵零件(jian)的(de)(de)工(gong)作(zuo)臺及拆裝工(gong)具(ju),切(qie)勿(wu)任(ren)意(yi)亂(luan)放亂(luan)用,避免(mian)碰壞泵的(de)(de)零部件(jian)。
拆對分(fen)式聯軸(zhou)器(qi)(qi):先(xian)把(ba)聯軸(zhou)器(qi)(qi)的(de)固定內(nei)六角螺(luo)釘擰(ning)下(xia)來,再輕(qing)(qing)輕(qing)(qing)把(ba)聯軸(zhou)器(qi)(qi)的(de)一(yi)半(ban)從軸(zhou)上(shang)慢慢拉下(xia),注意(yi)不要掉(diao)了,再用梅花扳手(shou)擰(ning)下(xia)泵(beng)軸(zhou)吊緊(jin)螺(luo)栓和擋(dang)塊,讓葉輪慢慢下(xia)沉至(zhi)泵(beng)體(ti),然后拆下(xia)另外一(yi)半(ban)聯軸(zhou)器(qi)(qi),拿下(xia)泵(beng)軸(zhou)擋(dang)圈(quan)。
拆卸合作機械密封:抓住密封彈簧(huang)順著泵軸往上提,就能拆(chai)下來(lai)了(le)。
拆(chai)(chai)卸(xie)并(bing)清洗軸(zhou)承(cheng)座(zuo):先輕輕松動一下軸(zhou)承(cheng)座(zuo)后用(yong)(yong)拆(chai)(chai)卸(xie)螺栓頂(ding)起軸(zhou)承(cheng)座(zuo),并(bing)且沿著(zhu)泵軸(zhou)往上提而(er)卸(xie)下,再用(yong)(yong)噴氣(qi)燃料清洗軸(zhou)承(cheng)及座(zuo),裝前晾(liang)干并(bing)涂抹少許20號機械油用(yong)(yong)來潤滑保護。
拆(chai)密封(feng)(feng)座(zuo):擰下(xia)密封(feng)(feng)座(zuo)壓緊螺母,輕(qing)輕(qing)卸下(xia)密封(feng)(feng)座(zuo)并清(qing)洗。
合作機械密封裝(zhuang)(zhuang)配:在(zai)動、靜(jing)環(huan)鏡面上(shang)涂(tu)一(yi)層潔凈的20號潤滑(hua)油(you),導(dao)軸(zhou)承座也抹(mo)上(shang)潤滑(hua)油(you),先把(ba)靜(jing)環(huan)輕輕定(ding)位(wei)裝(zhuang)(zhuang)入導(dao)軸(zhou)承座,再(zai)在(zai)泵軸(zhou)上(shang)抹(mo)上(shang)潤滑(hua)油(you),把(ba)動環(huan)部分輕輕裝(zhuang)(zhuang)入泵軸(zhou)上(shang),用手輕推(tui)密封環(huan)應能(neng)伸縮自如,注(zhu)意動、靜(jing)環(huan)部分的防(fang)轉部位(wei)需裝(zhuang)(zhuang)配到(dao)位(wei)。
裝(zhuang)聯(lian)(lian)(lian)軸(zhou)(zhou)器:在電機軸(zhou)(zhou)頭上(shang)裝(zhuang)上(shang)擋圈,裝(zhuang)上(shang)一(yi)半聯(lian)(lian)(lian)軸(zhou)(zhou)器,再在泵(beng)軸(zhou)(zhou)端和聯(lian)(lian)(lian)軸(zhou)(zhou)器槽內裝(zhuang)上(shang)擋塊并用梅花扳手(shou)擰(ning)緊螺(luo)栓;再裝(zhuang)上(shang)另一(yi)半聯(lian)(lian)(lian)軸(zhou)(zhou)器擰(ning)上(shang)內六(liu)角螺(luo)釘。安裝(zhuang)聯(lian)(lian)(lian)軸(zhou)(zhou)器正確的檢查要(yao)求:對分式聯(lian)(lian)(lian)軸(zhou)(zhou)器上(shang)下間隙需要(yao)均勻,用手(shou)盤動(dong)(dong)聯(lian)(lian)(lian)軸(zhou)(zhou)器幾圈檢查轉動(dong)(dong)的靈活(huo)性。
裝密封座(zuo):先將(jiang)密封座(zuo)裝入橡膠(jiao)油(you)封,再(zai)把密封座(zuo)裝入泵蓋(gai)(gai)(gai)并壓(ya)在軸(zhou)(zhou)(zhou)承座(zuo)上,擰緊螺母,確保(bao)所有(you)安裝螺釘緊固(gu)。當(dang)安裝螺釘被用(yong)作密封與(yu)(yu)軸(zhou)(zhou)(zhou)之(zhi)間(jian)的(de)驅動時,軸(zhou)(zhou)(zhou)應打埋頭孔來加固(gu)連(lian)接(jie),緊固(gu)壓(ya)蓋(gai)(gai)(gai)螺栓時應該平穩緊固(gu),并且不要使壓(ya)蓋(gai)(gai)(gai)受彈(dan)力。在可能(neng)的(de)地方使用(yong)4個以上螺釘的(de)等間(jian)距壓(ya)蓋(gai)(gai)(gai),緊固(gu)壓(ya)蓋(gai)(gai)(gai)螺栓時,用(yong)塞尺檢查(cha)軸(zhou)(zhou)(zhou)與(yu)(yu)壓(ya)蓋(gai)(gai)(gai)之(zhi)間(jian)的(de)間(jian)隙,這(zhe)在密封腔(qiang)對壓(ya)蓋(gai)(gai)(gai)不導向時,顯(xian)得(de)特別重要,因為壓(ya)蓋(gai)(gai)(gai)必須對中(zhong)。
