原平機械密封利用(yong)(yong)機械(xie)方式(shi)(shi)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)力(li)和(he)運(yun)動(dong)(dong)(dong)(dong)(dong)的傳(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)工程(cheng)中應用(yong)(yong)非常(chang)廣泛,有多(duo)種形式(shi)(shi),主要包括皮(pi)帶(dai)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒輪(lun)(lun)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(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒輪(lun)(lun)齒條傳(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。齒輪(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)能夠用(yong)(yong)于(yu)大功率(lv)的場(chang)合(he)(he),傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比準(zhun)確,但(dan)一(yi)般(ban)要求較高的制造精度和(he)安裝精度。還有一(yi)類是(shi)靠機件間的摩(mo)擦(ca)力(li)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)力(li)和(he)運(yun)動(dong)(dong)(dong)(dong)(dong)的摩(mo)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(mo)擦(ca)輪(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等。摩(mo)擦(ca)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)容易實(shi)現無級變速,可以適應軸間距較大的傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)場(chang)合(he)(he),而過(guo)載打滑還能起到(dao)緩沖和(he)保護傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)裝置的作用(yong)(yong),但(dan)這種傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)一(yi)般(ban)不能用(yong)(yong)于(yu)大功率(lv)的場(chang)合(he)(he),也不能保證準(zhun)確的傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比。
傳動形式多,但是原平機械密封的(de)更(geng)換工作大同小異,首先拆前需確(que)認電(dian)機處(chu)于(yu)檢修狀(zhuang)態(tai),擰下加油螺塞,用吸管把密封座腔內的(de)潤滑油吸出(chu)。準(zhun)備好放置泵(beng)(beng)零件(jian)的(de)工作臺及拆裝(zhuang)工具,切勿(wu)任意(yi)亂放亂用,避免碰(peng)壞泵(beng)(beng)的(de)零部件(jian)。
拆對(dui)分式聯(lian)軸(zhou)器(qi)(qi):先(xian)把聯(lian)軸(zhou)器(qi)(qi)的(de)固定內六角螺釘擰下(xia)來,再(zai)輕(qing)輕(qing)把聯(lian)軸(zhou)器(qi)(qi)的(de)一(yi)半從軸(zhou)上慢(man)慢(man)拉下(xia),注(zhu)意不要掉了(le),再(zai)用梅花扳手擰下(xia)泵軸(zhou)吊緊螺栓(shuan)和擋(dang)塊,讓葉輪慢(man)慢(man)下(xia)沉至泵體,然后拆下(xia)另外一(yi)半聯(lian)軸(zhou)器(qi)(qi),拿下(xia)泵軸(zhou)擋(dang)圈。
拆卸原平機械密封:抓住密(mi)封(feng)彈簧順著泵軸(zhou)往上提,就能(neng)拆下(xia)來了。
拆(chai)卸并(bing)清(qing)洗軸(zhou)承座(zuo):先輕(qing)輕(qing)松(song)動一下軸(zhou)承座(zuo)后用拆(chai)卸螺(luo)栓(shuan)頂起軸(zhou)承座(zuo),并(bing)且沿著泵軸(zhou)往上提而卸下,再用噴氣燃料清(qing)洗軸(zhou)承及座(zuo),裝前晾干并(bing)涂抹少許20號機械油用來潤(run)滑(hua)保護(hu)。
拆密封座(zuo):擰下(xia)密封座(zuo)壓(ya)緊螺母(mu),輕輕卸下(xia)密封座(zuo)并清洗。
原平機械密封裝配(pei):在(zai)動(dong)(dong)、靜(jing)環鏡面上(shang)涂一層潔凈的20號潤滑油(you),導軸(zhou)(zhou)承座也(ye)抹上(shang)潤滑油(you),先把(ba)靜(jing)環輕(qing)(qing)輕(qing)(qing)定位(wei)裝入(ru)導軸(zhou)(zhou)承座,再在(zai)泵(beng)軸(zhou)(zhou)上(shang)抹上(shang)潤滑油(you),把(ba)動(dong)(dong)環部(bu)分輕(qing)(qing)輕(qing)(qing)裝入(ru)泵(beng)軸(zhou)(zhou)上(shang),用手(shou)輕(qing)(qing)推密封環應能(neng)伸縮(suo)自如,注意動(dong)(dong)、靜(jing)環部(bu)分的防轉部(bu)位(wei)需裝配(pei)到位(wei)。
裝(zhuang)聯(lian)(lian)軸(zhou)(zhou)器:在(zai)電機軸(zhou)(zhou)頭上(shang)(shang)裝(zhuang)上(shang)(shang)擋(dang)圈,裝(zhuang)上(shang)(shang)一(yi)半聯(lian)(lian)軸(zhou)(zhou)器,再在(zai)泵軸(zhou)(zhou)端和聯(lian)(lian)軸(zhou)(zhou)器槽內裝(zhuang)上(shang)(shang)擋(dang)塊并用(yong)梅花扳(ban)手擰緊螺(luo)栓;再裝(zhuang)上(shang)(shang)另(ling)一(yi)半聯(lian)(lian)軸(zhou)(zhou)器擰上(shang)(shang)內六角螺(luo)釘。安裝(zhuang)聯(lian)(lian)軸(zhou)(zhou)器正(zheng)確的檢查要求(qiu):對分式聯(lian)(lian)軸(zhou)(zhou)器上(shang)(shang)下間隙(xi)需要均(jun)勻,用(yong)手盤動聯(lian)(lian)軸(zhou)(zhou)器幾(ji)圈檢查轉動的靈活性。
裝(zhuang)密封(feng)座:先將密封(feng)座裝(zhuang)入(ru)橡膠油封(feng),再把密封(feng)座裝(zhuang)入(ru)泵蓋(gai)并壓(ya)(ya)(ya)在軸承(cheng)座上,擰緊(jin)(jin)螺(luo)(luo)(luo)母,確保所有安(an)裝(zhuang)螺(luo)(luo)(luo)釘(ding)緊(jin)(jin)固(gu)。當安(an)裝(zhuang)螺(luo)(luo)(luo)釘(ding)被用作密封(feng)與(yu)軸之間(jian)的(de)(de)(de)驅(qu)動時,軸應(ying)打埋頭孔(kong)來加固(gu)連接,緊(jin)(jin)固(gu)壓(ya)(ya)(ya)蓋(gai)螺(luo)(luo)(luo)栓時應(ying)該平(ping)穩緊(jin)(jin)固(gu),并且不(bu)要使壓(ya)(ya)(ya)蓋(gai)受(shou)彈(dan)力。在可能的(de)(de)(de)地方使用4個(ge)以(yi)上螺(luo)(luo)(luo)釘(ding)的(de)(de)(de)等(deng)間(jian)距壓(ya)(ya)(ya)蓋(gai),緊(jin)(jin)固(gu)壓(ya)(ya)(ya)蓋(gai)螺(luo)(luo)(luo)栓時,用塞(sai)尺(chi)檢查軸與(yu)壓(ya)(ya)(ya)蓋(gai)之間(jian)的(de)(de)(de)間(jian)隙,這在密封(feng)腔對壓(ya)(ya)(ya)蓋(gai)不(bu)導向時,顯(xian)得特(te)別重要,因為(wei)壓(ya)(ya)(ya)蓋(gai)必須對中(zhong)。
