德清機械密封利用(yong)機(ji)(ji)械方式傳(chuan)遞動(dong)(dong)(dong)(dong)(dong)力(li)和(he)運(yun)動(dong)(dong)(dong)(dong)(dong)的傳(chuan)動(dong)(dong)(dong)(dong)(dong)，機(ji)(ji)械傳(chuan)動(dong)(dong)(dong)(dong)(dong)在機(ji)(ji)械工程中應用(yong)非常(chang)廣泛，有(you)多種形式，主要(yao)包括(kuo)皮(pi)帶傳(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)(chi)輪(lun)(lun)傳(chuan)動(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)動(dong)(dong)(dong)(dong)(dong)、蝸(gua)桿蝸(gua)輪(lun)(lun)傳(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)(chi)輪(lun)(lun)齒(chi)(chi)條傳(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)螺旋(xuan)傳(chuan)動(dong)(dong)(dong)(dong)(dong)等。齒(chi)(chi)輪(lun)(lun)傳(chuan)動(dong)(dong)(dong)(dong)(dong)能夠用(yong)于大(da)功率(lv)的場合(he)，傳(chuan)動(dong)(dong)(dong)(dong)(dong)比準(zhun)確，但一(yi)般(ban)要(yao)求較(jiao)高的制(zhi)造精(jing)(jing)度(du)和(he)安裝精(jing)(jing)度(du)。還(huan)有(you)一(yi)類是靠機(ji)(ji)件間的摩(mo)擦(ca)力(li)傳(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)動(dong)(dong)(dong)(dong)(dong)，包括(kuo)帶傳(chuan)動(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)摩(mo)擦(ca)輪(lun)(lun)傳(chuan)動(dong)(dong)(dong)(dong)(dong)等。摩(mo)擦(ca)傳(chuan)動(dong)(dong)(dong)(dong)(dong)容(rong)易實(shi)現無級變速，可以(yi)適應軸間距較(jiao)大(da)的傳(chuan)動(dong)(dong)(dong)(dong)(dong)場合(he)，而過載(zai)打滑還(huan)能起到(dao)緩沖和(he)保護傳(chuan)動(dong)(dong)(dong)(dong)(dong)裝置的作(zuo)用(yong)，但這種傳(chuan)動(dong)(dong)(dong)(dong)(dong)一(yi)般(ban)不能用(yong)于大(da)功率(lv)的場合(he)，也不能保證(zheng)準(zhun)確的傳(chuan)動(dong)(dong)(dong)(dong)(dong)比。

　　傳動形式多，但是德清機械密封的更換(huan)工(gong)作大同小(xiao)異，首先(xian)拆前需確認電機處于檢修狀態，擰(ning)下(xia)加油螺塞(sai)，用(yong)吸(xi)管把密封座腔內的潤滑油吸(xi)出。準備好放置泵零(ling)件的工(gong)作臺及(ji)拆裝工(gong)具，切勿任意(yi)亂放亂用(yong)，避免碰(peng)壞泵的零(ling)部(bu)件。

　　拆對分式聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器：先把(ba)聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器的(de)固定內六(liu)角螺釘擰下來，再輕輕把(ba)聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器的(de)一(yi)半從軸(zhou)(zhou)(zhou)(zhou)上慢慢拉下，注意不要掉了(le)，再用梅花扳手擰下泵軸(zhou)(zhou)(zhou)(zhou)吊緊螺栓和擋塊，讓葉輪慢慢下沉至泵體(ti)，然后拆下另外一(yi)半聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器，拿下泵軸(zhou)(zhou)(zhou)(zhou)擋圈。

　　拆卸德清機械密封：抓住密封彈(dan)簧順(shun)著泵(beng)軸往上(shang)提(ti)，就能(neng)拆下來了(le)。

　　拆(chai)卸并(bing)清(qing)洗軸(zhou)(zhou)(zhou)承(cheng)座：先輕輕松動(dong)一下(xia)(xia)軸(zhou)(zhou)(zhou)承(cheng)座后用(yong)(yong)拆(chai)卸螺(luo)栓頂起軸(zhou)(zhou)(zhou)承(cheng)座，并(bing)且(qie)沿著泵軸(zhou)(zhou)(zhou)往上提而卸下(xia)(xia)，再用(yong)(yong)噴(pen)氣燃料清(qing)洗軸(zhou)(zhou)(zhou)承(cheng)及座，裝前晾(liang)干并(bing)涂抹少許20號(hao)機(ji)械(xie)油用(yong)(yong)來潤滑保護(hu)。

　　拆密(mi)封(feng)(feng)座(zuo)：擰下密(mi)封(feng)(feng)座(zuo)壓緊螺母，輕輕卸下密(mi)封(feng)(feng)座(zuo)并清洗。

　　德清機械密封裝(zhuang)配(pei)：在(zai)動、靜(jing)環鏡面上涂(tu)一層潔凈的(de)20號潤滑油，導軸(zhou)承座也抹(mo)上潤滑油，先(xian)把靜(jing)環輕(qing)(qing)(qing)輕(qing)(qing)(qing)定位裝(zhuang)入導軸(zhou)承座，再在(zai)泵軸(zhou)上抹(mo)上潤滑油，把動環部分(fen)輕(qing)(qing)(qing)輕(qing)(qing)(qing)裝(zhuang)入泵軸(zhou)上，用手輕(qing)(qing)(qing)推密封環應能伸(shen)縮自如，注意動、靜(jing)環部分(fen)的(de)防轉部位需裝(zhuang)配(pei)到(dao)位。

　　裝(zhuang)(zhuang)聯軸器(qi)(qi)(qi)：在電機軸頭上(shang)(shang)裝(zhuang)(zhuang)上(shang)(shang)擋圈，裝(zhuang)(zhuang)上(shang)(shang)一半(ban)聯軸器(qi)(qi)(qi)，再(zai)在泵軸端和聯軸器(qi)(qi)(qi)槽(cao)內裝(zhuang)(zhuang)上(shang)(shang)擋塊并(bing)用梅(mei)花扳(ban)手擰(ning)緊螺(luo)栓；再(zai)裝(zhuang)(zhuang)上(shang)(shang)另一半(ban)聯軸器(qi)(qi)(qi)擰(ning)上(shang)(shang)內六角(jiao)螺(luo)釘。安(an)裝(zhuang)(zhuang)聯軸器(qi)(qi)(qi)正確的檢查(cha)要求：對分式聯軸器(qi)(qi)(qi)上(shang)(shang)下(xia)間隙需要均勻，用手盤動聯軸器(qi)(qi)(qi)幾圈檢查(cha)轉動的靈活性。

　　裝密(mi)(mi)封(feng)座：先將(jiang)密(mi)(mi)封(feng)座裝入橡膠油封(feng)，再(zai)把密(mi)(mi)封(feng)座裝入泵蓋(gai)(gai)并壓(ya)在(zai)軸承座上，擰(ning)緊(jin)螺母，確保所有安裝螺釘緊(jin)固(gu)(gu)(gu)。當(dang)安裝螺釘被用(yong)作密(mi)(mi)封(feng)與軸之(zhi)間(jian)的驅動時(shi)(shi)，軸應(ying)打埋頭(tou)孔來加(jia)固(gu)(gu)(gu)連接，緊(jin)固(gu)(gu)(gu)壓(ya)蓋(gai)(gai)螺栓時(shi)(shi)應(ying)該平穩緊(jin)固(gu)(gu)(gu)，并且(qie)不(bu)要(yao)(yao)使壓(ya)蓋(gai)(gai)受彈力(li)。在(zai)可能(neng)的地方使用(yong)4個(ge)以上螺釘的等間(jian)距壓(ya)蓋(gai)(gai)，緊(jin)固(gu)(gu)(gu)壓(ya)蓋(gai)(gai)螺栓時(shi)(shi)，用(yong)塞尺檢查軸與壓(ya)蓋(gai)(gai)之(zhi)間(jian)的間(jian)隙，這在(zai)密(mi)(mi)封(feng)腔對(dui)壓(ya)蓋(gai)(gai)不(bu)導向時(shi)(shi)，顯得特別(bie)重要(yao)(yao)，因為壓(ya)蓋(gai)(gai)必須對(dui)中。
