舟曲機械密封利用機(ji)(ji)械方式傳(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)(dong)力和(he)運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)，機(ji)(ji)械傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)在機(ji)(ji)械工程中應用非常廣泛，有多種形(xing)式，主要包(bao)括(kuo)皮帶傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、齒(chi)(chi)輪(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、蝸(gua)桿蝸(gua)輪(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、齒(chi)(chi)輪(lun)(lun)齒(chi)(chi)條傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)和(he)螺旋傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)等(deng)(deng)。齒(chi)(chi)輪(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)能(neng)夠(gou)用于(yu)大(da)功(gong)率的(de)(de)(de)場合，傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比(bi)準確，但(dan)一(yi)(yi)般要求較(jiao)高(gao)的(de)(de)(de)制造精度和(he)安(an)裝精度。還有一(yi)(yi)類是靠機(ji)(ji)件間的(de)(de)(de)摩擦力傳(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)(dong)力和(he)運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)摩擦傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)，包(bao)括(kuo)帶傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)和(he)摩擦輪(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)等(deng)(deng)。摩擦傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)容易實現無級變速(su)，可以適應軸(zhou)間距較(jiao)大(da)的(de)(de)(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)場合，而(er)過(guo)載打滑還能(neng)起(qi)到緩沖(chong)和(he)保(bao)護傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)裝置的(de)(de)(de)作用，但(dan)這種傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)一(yi)(yi)般不能(neng)用于(yu)大(da)功(gong)率的(de)(de)(de)場合，也不能(neng)保(bao)證準確的(de)(de)(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比(bi)。

　　傳動形式多，但是舟曲機械密封的更換工作大同小異，首先拆前需確認電機處于檢修狀(zhuang)態，擰下加油螺塞，用(yong)吸管把密封座(zuo)腔內的潤滑油吸出。準備好放置泵(beng)零件的工作臺(tai)及拆裝(zhuang)工具，切勿任(ren)意亂(luan)放亂(luan)用(yong)，避免碰壞泵(beng)的零部(bu)件。

　　拆對分式(shi)聯(lian)軸(zhou)(zhou)器：先把(ba)聯(lian)軸(zhou)(zhou)器的固(gu)定內六角螺釘(ding)擰下(xia)(xia)來，再輕輕把(ba)聯(lian)軸(zhou)(zhou)器的一半(ban)從軸(zhou)(zhou)上慢(man)慢(man)拉下(xia)(xia)，注意不要掉了，再用梅(mei)花扳(ban)手擰下(xia)(xia)泵軸(zhou)(zhou)吊緊(jin)螺栓和(he)擋(dang)塊，讓葉輪慢(man)慢(man)下(xia)(xia)沉(chen)至泵體，然后(hou)拆下(xia)(xia)另外一半(ban)聯(lian)軸(zhou)(zhou)器，拿(na)下(xia)(xia)泵軸(zhou)(zhou)擋(dang)圈(quan)。

　　拆卸舟曲機械密封：抓(zhua)住密封彈簧順(shun)著泵軸往上提，就(jiu)能拆下來了。

　　拆(chai)卸(xie)并清洗軸(zhou)承(cheng)座(zuo)：先輕(qing)輕(qing)松動一下軸(zhou)承(cheng)座(zuo)后用拆(chai)卸(xie)螺(luo)栓頂起軸(zhou)承(cheng)座(zuo)，并且沿著泵軸(zhou)往(wang)上提而(er)卸(xie)下，再用噴氣燃料清洗軸(zhou)承(cheng)及座(zuo)，裝前(qian)晾(liang)干并涂抹少許20號機械油用來潤滑保護。

　　拆密(mi)封座(zuo)：擰下密(mi)封座(zuo)壓緊螺(luo)母，輕(qing)輕(qing)卸下密(mi)封座(zuo)并(bing)清(qing)洗(xi)。

　　舟曲機械密封裝(zhuang)配(pei)：在動、靜(jing)環鏡面上(shang)(shang)涂一層潔凈的(de)20號潤滑油，導軸(zhou)(zhou)承座也抹上(shang)(shang)潤滑油，先把(ba)靜(jing)環輕(qing)(qing)輕(qing)(qing)定位(wei)裝(zhuang)入導軸(zhou)(zhou)承座，再在泵軸(zhou)(zhou)上(shang)(shang)抹上(shang)(shang)潤滑油，把(ba)動環部(bu)分輕(qing)(qing)輕(qing)(qing)裝(zhuang)入泵軸(zhou)(zhou)上(shang)(shang)，用(yong)手輕(qing)(qing)推密封環應能(neng)伸縮自如(ru)，注意(yi)動、靜(jing)環部(bu)分的(de)防轉部(bu)位(wei)需裝(zhuang)配(pei)到位(wei)。

　　裝(zhuang)聯(lian)軸(zhou)器(qi)(qi)(qi)：在(zai)電機軸(zhou)頭上裝(zhuang)上擋圈，裝(zhuang)上一(yi)半聯(lian)軸(zhou)器(qi)(qi)(qi)，再(zai)在(zai)泵(beng)軸(zhou)端和(he)聯(lian)軸(zhou)器(qi)(qi)(qi)槽內裝(zhuang)上擋塊并用梅花(hua)扳手(shou)擰緊螺栓(shuan)；再(zai)裝(zhuang)上另一(yi)半聯(lian)軸(zhou)器(qi)(qi)(qi)擰上內六角螺釘(ding)。安裝(zhuang)聯(lian)軸(zhou)器(qi)(qi)(qi)正確的檢查(cha)要求：對分(fen)式聯(lian)軸(zhou)器(qi)(qi)(qi)上下(xia)間隙需要均勻，用手(shou)盤動(dong)聯(lian)軸(zhou)器(qi)(qi)(qi)幾圈檢查(cha)轉動(dong)的靈活性。

　　裝密(mi)封(feng)座(zuo)(zuo)：先將密(mi)封(feng)座(zuo)(zuo)裝入橡膠油封(feng)，再把密(mi)封(feng)座(zuo)(zuo)裝入泵蓋(gai)(gai)并壓(ya)在軸(zhou)承座(zuo)(zuo)上，擰(ning)緊(jin)螺(luo)母，確保(bao)所有安(an)裝螺(luo)釘(ding)緊(jin)固。當安(an)裝螺(luo)釘(ding)被用作(zuo)密(mi)封(feng)與軸(zhou)之間(jian)的驅動時(shi)(shi)，軸(zhou)應打埋(mai)頭孔(kong)來加固連(lian)接，緊(jin)固壓(ya)蓋(gai)(gai)螺(luo)栓時(shi)(shi)應該平穩緊(jin)固，并且(qie)不要使(shi)壓(ya)蓋(gai)(gai)受彈力。在可(ke)能(neng)的地方使(shi)用4個以上螺(luo)釘(ding)的等間(jian)距壓(ya)蓋(gai)(gai)，緊(jin)固壓(ya)蓋(gai)(gai)螺(luo)栓時(shi)(shi)，用塞(sai)尺檢查軸(zhou)與壓(ya)蓋(gai)(gai)之間(jian)的間(jian)隙(xi)，這在密(mi)封(feng)腔對(dui)壓(ya)蓋(gai)(gai)不導向時(shi)(shi)，顯得特別重要，因(yin)為(wei)壓(ya)蓋(gai)(gai)必須對(dui)中。
