道滘鎮機械密封利用機(ji)械(xie)方(fang)式傳(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)力和運動(dong)(dong)(dong)(dong)的(de)(de)(de)(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)，機(ji)械(xie)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)在機(ji)械(xie)工程中應(ying)用非常廣泛，有(you)(you)多種形式，主(zhu)要包(bao)括(kuo)皮帶(dai)(dai)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、蝸(gua)桿蝸(gua)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒(chi)輪(lun)齒(chi)條傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)和螺(luo)旋傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)等(deng)。齒(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)能(neng)夠用于(yu)大功率的(de)(de)(de)(de)場合(he)，傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)比準(zhun)(zhun)確，但一般要求較高的(de)(de)(de)(de)制造精(jing)度和安裝精(jing)度。還有(you)(you)一類是(shi)靠機(ji)件間的(de)(de)(de)(de)摩(mo)(mo)擦(ca)(ca)(ca)力傳(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)力和運動(dong)(dong)(dong)(dong)的(de)(de)(de)(de)摩(mo)(mo)擦(ca)(ca)(ca)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)，包(bao)括(kuo)帶(dai)(dai)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)和摩(mo)(mo)擦(ca)(ca)(ca)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)等(deng)。摩(mo)(mo)擦(ca)(ca)(ca)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)容易實(shi)現無(wu)級變速(su)，可(ke)以適應(ying)軸間距較大的(de)(de)(de)(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)場合(he)，而過載打滑還能(neng)起到緩沖和保護(hu)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)裝置的(de)(de)(de)(de)作用，但這種傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)一般不能(neng)用于(yu)大功率的(de)(de)(de)(de)場合(he)，也不能(neng)保證準(zhun)(zhun)確的(de)(de)(de)(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)比。

　　傳動形式多，但是道滘鎮機械密封的更換工作大同小異，首先拆(chai)前需確認電機處于檢(jian)修狀態，擰(ning)下(xia)加(jia)油(you)螺塞，用吸管(guan)把(ba)密封座腔內的潤滑油(you)吸出。準(zhun)備好放(fang)置(zhi)泵(beng)零(ling)件的工作臺及(ji)拆(chai)裝工具，切勿(wu)任意亂放(fang)亂用，避(bi)免碰壞泵(beng)的零(ling)部件。

　　拆(chai)對(dui)分式聯軸(zhou)器(qi)(qi)：先把聯軸(zhou)器(qi)(qi)的(de)固定內六(liu)角螺釘擰(ning)下來，再輕輕把聯軸(zhou)器(qi)(qi)的(de)一半(ban)從(cong)軸(zhou)上(shang)慢(man)慢(man)拉下，注意不要掉了，再用梅花扳手擰(ning)下泵軸(zhou)吊(diao)緊(jin)螺栓和擋塊，讓葉輪慢(man)慢(man)下沉至(zhi)泵體(ti)，然后拆(chai)下另(ling)外(wai)一半(ban)聯軸(zhou)器(qi)(qi)，拿下泵軸(zhou)擋圈。

　　拆卸道滘鎮機械密封：抓住(zhu)密封彈簧順著泵軸往上提，就能拆下來(lai)了。

　　拆卸(xie)并(bing)清洗軸承座(zuo)：先輕輕松動一(yi)下軸承座(zuo)后用(yong)拆卸(xie)螺栓(shuan)頂起軸承座(zuo)，并(bing)且沿著泵(beng)軸往上提而(er)卸(xie)下，再(zai)用(yong)噴(pen)氣燃料清洗軸承及座(zuo)，裝(zhuang)前晾(liang)干并(bing)涂(tu)抹少許20號機械油用(yong)來潤滑保護。

　　拆密(mi)封(feng)(feng)座(zuo)：擰下(xia)密(mi)封(feng)(feng)座(zuo)壓緊螺母，輕(qing)輕(qing)卸下(xia)密(mi)封(feng)(feng)座(zuo)并(bing)清洗。

　　道滘鎮機械密封裝配(pei)：在動、靜環(huan)鏡面上(shang)涂一層潔凈(jing)的(de)20號潤滑油(you)(you)，導軸(zhou)承座也抹(mo)上(shang)潤滑油(you)(you)，先把(ba)靜環(huan)輕(qing)(qing)輕(qing)(qing)定(ding)位(wei)裝入(ru)導軸(zhou)承座，再(zai)在泵軸(zhou)上(shang)抹(mo)上(shang)潤滑油(you)(you)，把(ba)動環(huan)部分(fen)輕(qing)(qing)輕(qing)(qing)裝入(ru)泵軸(zhou)上(shang)，用手輕(qing)(qing)推密封環(huan)應能伸縮(suo)自如，注意(yi)動、靜環(huan)部分(fen)的(de)防轉(zhuan)部位(wei)需(xu)裝配(pei)到位(wei)。

　　裝(zhuang)(zhuang)(zhuang)聯(lian)(lian)軸(zhou)器(qi)：在電(dian)機(ji)軸(zhou)頭上(shang)裝(zhuang)(zhuang)(zhuang)上(shang)擋(dang)圈(quan)，裝(zhuang)(zhuang)(zhuang)上(shang)一半聯(lian)(lian)軸(zhou)器(qi)，再(zai)在泵軸(zhou)端(duan)和(he)聯(lian)(lian)軸(zhou)器(qi)槽內(nei)裝(zhuang)(zhuang)(zhuang)上(shang)擋(dang)塊(kuai)并(bing)用梅花扳(ban)手擰緊螺(luo)栓；再(zai)裝(zhuang)(zhuang)(zhuang)上(shang)另(ling)一半聯(lian)(lian)軸(zhou)器(qi)擰上(shang)內(nei)六角(jiao)螺(luo)釘。安裝(zhuang)(zhuang)(zhuang)聯(lian)(lian)軸(zhou)器(qi)正確的檢查要(yao)求：對分(fen)式(shi)聯(lian)(lian)軸(zhou)器(qi)上(shang)下間隙需要(yao)均勻，用手盤(pan)動聯(lian)(lian)軸(zhou)器(qi)幾圈(quan)檢查轉(zhuan)動的靈活性(xing)。

　　裝(zhuang)(zhuang)密封(feng)座：先將密封(feng)座裝(zhuang)(zhuang)入橡膠油封(feng)，再把密封(feng)座裝(zhuang)(zhuang)入泵蓋(gai)并壓在軸(zhou)承(cheng)座上，擰緊(jin)(jin)(jin)螺母(mu)，確保(bao)所有安裝(zhuang)(zhuang)螺釘緊(jin)(jin)(jin)固。當安裝(zhuang)(zhuang)螺釘被用作密封(feng)與軸(zhou)之間(jian)的驅動時，軸(zhou)應(ying)打埋(mai)頭孔來加(jia)固連接，緊(jin)(jin)(jin)固壓蓋(gai)螺栓時應(ying)該平穩緊(jin)(jin)(jin)固，并且不(bu)要使(shi)壓蓋(gai)受彈力。在可能的地(di)方使(shi)用4個以上螺釘的等間(jian)距壓蓋(gai)，緊(jin)(jin)(jin)固壓蓋(gai)螺栓時，用塞尺檢查軸(zhou)與壓蓋(gai)之間(jian)的間(jian)隙，這(zhe)在密封(feng)腔(qiang)對壓蓋(gai)不(bu)導向時，顯得特別重(zhong)要，因為壓蓋(gai)必須(xu)對中。
