當陽機械密封利(li)用(yong)機械(xie)方式傳(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)力和運動(dong)(dong)(dong)(dong)的(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)，機械(xie)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)在機械(xie)工程中應(ying)用(yong)非常(chang)廣泛(fan)，有多種形式，主要包括皮(pi)帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒(chi)(chi)(chi)輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、蝸桿蝸輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒(chi)(chi)(chi)輪(lun)齒(chi)(chi)(chi)條傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)和螺旋傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)等。齒(chi)(chi)(chi)輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)能(neng)(neng)夠(gou)用(yong)于大(da)功率的(de)場合(he)，傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)比準確，但(dan)一般要求較高(gao)的(de)制造精(jing)度和安裝(zhuang)精(jing)度。還有一類是靠機件間(jian)的(de)摩(mo)(mo)(mo)擦力傳(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)力和運動(dong)(dong)(dong)(dong)的(de)摩(mo)(mo)(mo)擦傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)，包括帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)和摩(mo)(mo)(mo)擦輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)等。摩(mo)(mo)(mo)擦傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)容易實現無級(ji)變速(su)，可以適應(ying)軸間(jian)距較大(da)的(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)場合(he)，而(er)過載打滑還能(neng)(neng)起到緩沖和保護傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)裝(zhuang)置的(de)作(zuo)用(yong)，但(dan)這種傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)一般不能(neng)(neng)用(yong)于大(da)功率的(de)場合(he)，也(ye)不能(neng)(neng)保證準確的(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)比。

　　傳動形式多，但是當陽機械密封的(de)更換工作大同小異，首先拆(chai)前需確認電機處于檢修狀態，擰下加(jia)油(you)螺塞，用吸(xi)管把密封座腔內的(de)潤(run)滑油(you)吸(xi)出。準(zhun)備好放(fang)(fang)置泵(beng)零(ling)件的(de)工作臺及拆(chai)裝(zhuang)工具，切勿任(ren)意亂(luan)放(fang)(fang)亂(luan)用，避免碰壞(huai)泵(beng)的(de)零(ling)部(bu)件。

　　拆對分式(shi)聯(lian)軸(zhou)(zhou)器：先把聯(lian)軸(zhou)(zhou)器的固(gu)定內六角螺釘(ding)擰下(xia)來(lai)，再輕輕把聯(lian)軸(zhou)(zhou)器的一半從軸(zhou)(zhou)上(shang)慢慢拉下(xia)，注(zhu)意不要掉了，再用梅花扳(ban)手(shou)擰下(xia)泵軸(zhou)(zhou)吊緊螺栓和擋(dang)塊(kuai)，讓葉輪慢慢下(xia)沉(chen)至泵體，然后拆下(xia)另外一半聯(lian)軸(zhou)(zhou)器，拿下(xia)泵軸(zhou)(zhou)擋(dang)圈(quan)。

　　拆卸當陽機械密封：抓住(zhu)密封彈(dan)簧順著泵軸往(wang)上提(ti)，就能拆下來了。

　　拆卸并清洗軸(zhou)承(cheng)座(zuo)：先輕輕松動一下軸(zhou)承(cheng)座(zuo)后用(yong)拆卸螺栓頂起軸(zhou)承(cheng)座(zuo)，并且沿著泵軸(zhou)往上(shang)提而卸下，再用(yong)噴氣燃料清洗軸(zhou)承(cheng)及座(zuo)，裝(zhuang)前晾干并涂抹少許20號機械油(you)用(yong)來(lai)潤滑保(bao)護。

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

　　當陽機械密封裝配：在動、靜(jing)(jing)環(huan)鏡面上(shang)涂一層潔凈(jing)的20號潤(run)滑(hua)油，導(dao)軸(zhou)承(cheng)座(zuo)也抹上(shang)潤(run)滑(hua)油，先把(ba)(ba)靜(jing)(jing)環(huan)輕(qing)(qing)輕(qing)(qing)定位(wei)(wei)裝入導(dao)軸(zhou)承(cheng)座(zuo)，再在泵軸(zhou)上(shang)抹上(shang)潤(run)滑(hua)油，把(ba)(ba)動環(huan)部(bu)分輕(qing)(qing)輕(qing)(qing)裝入泵軸(zhou)上(shang)，用手(shou)輕(qing)(qing)推密(mi)封(feng)環(huan)應(ying)能伸縮自如，注意動、靜(jing)(jing)環(huan)部(bu)分的防轉部(bu)位(wei)(wei)需裝配到位(wei)(wei)。

　　裝(zhuang)聯(lian)(lian)(lian)軸(zhou)器：在電(dian)機軸(zhou)頭上(shang)(shang)(shang)裝(zhuang)上(shang)(shang)(shang)擋圈(quan)，裝(zhuang)上(shang)(shang)(shang)一半(ban)聯(lian)(lian)(lian)軸(zhou)器，再在泵(beng)軸(zhou)端和聯(lian)(lian)(lian)軸(zhou)器槽(cao)內裝(zhuang)上(shang)(shang)(shang)擋塊并(bing)用(yong)梅花扳手擰緊螺栓；再裝(zhuang)上(shang)(shang)(shang)另(ling)一半(ban)聯(lian)(lian)(lian)軸(zhou)器擰上(shang)(shang)(shang)內六角螺釘。安裝(zhuang)聯(lian)(lian)(lian)軸(zhou)器正確的檢(jian)查要求：對分(fen)式聯(lian)(lian)(lian)軸(zhou)器上(shang)(shang)(shang)下間隙需要均勻，用(yong)手盤動聯(lian)(lian)(lian)軸(zhou)器幾圈(quan)檢(jian)查轉動的靈活性。

　　裝(zhuang)密(mi)(mi)(mi)封座(zuo)：先(xian)將密(mi)(mi)(mi)封座(zuo)裝(zhuang)入橡膠油封，再把密(mi)(mi)(mi)封座(zuo)裝(zhuang)入泵蓋(gai)并壓(ya)在軸承座(zuo)上，擰(ning)緊(jin)螺母，確保(bao)所有安裝(zhuang)螺釘(ding)緊(jin)固。當安裝(zhuang)螺釘(ding)被用作密(mi)(mi)(mi)封與軸之(zhi)間的(de)(de)驅動時，軸應(ying)打埋(mai)頭孔來加固連接，緊(jin)固壓(ya)蓋(gai)螺栓時應(ying)該平穩(wen)緊(jin)固，并且不(bu)要使壓(ya)蓋(gai)受彈(dan)力(li)。在可(ke)能的(de)(de)地方使用4個以上螺釘(ding)的(de)(de)等(deng)間距壓(ya)蓋(gai)，緊(jin)固壓(ya)蓋(gai)螺栓時，用塞(sai)尺檢查軸與壓(ya)蓋(gai)之(zhi)間的(de)(de)間隙，這在密(mi)(mi)(mi)封腔對壓(ya)蓋(gai)不(bu)導(dao)向時，顯(xian)得特別重要，因(yin)為壓(ya)蓋(gai)必須對中(zhong)。
