隴南機械密封利用(yong)機(ji)械(xie)方式傳(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)力(li)和(he)運動(dong)(dong)(dong)(dong)(dong)的傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，機(ji)械(xie)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)在(zai)機(ji)械(xie)工程中應(ying)用(yong)非常(chang)廣泛，有多種(zhong)(zhong)形式，主要包(bao)(bao)括皮帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)(chi)輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、鏈(lian)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、蝸桿蝸輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)(chi)輪(lun)齒(chi)(chi)條傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)螺旋傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等。齒(chi)(chi)輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)能(neng)夠用(yong)于大功(gong)率的場合，傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比準確(que)，但(dan)一般要求(qiu)較高的制造精(jing)度和(he)安裝(zhuang)精(jing)度。還有一類是(shi)靠機(ji)件間(jian)的摩擦力(li)傳(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)力(li)和(he)運動(dong)(dong)(dong)(dong)(dong)的摩擦傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，包(bao)(bao)括帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)摩擦輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等。摩擦傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)容(rong)易實現無級變速，可(ke)以適應(ying)軸間(jian)距較大的傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)場合，而過載打滑還能(neng)起到緩(huan)沖(chong)和(he)保護(hu)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)裝(zhuang)置的作用(yong)，但(dan)這種(zhong)(zhong)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)一般不能(neng)用(yong)于大功(gong)率的場合，也(ye)不能(neng)保證準確(que)的傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比。

　　傳動形式多，但是隴南機械密封的(de)更(geng)換工作(zuo)(zuo)大(da)同(tong)小異，首先拆前需確(que)認電機處于檢修(xiu)狀態，擰下(xia)加(jia)油(you)螺(luo)塞，用吸管(guan)把密封(feng)座(zuo)腔內的(de)潤(run)滑油(you)吸出。準備好放置(zhi)泵零(ling)件的(de)工作(zuo)(zuo)臺及拆裝工具，切勿(wu)任意亂放亂用，避免碰壞泵的(de)零(ling)部(bu)件。

　　拆對分式聯(lian)軸器(qi)：先把聯(lian)軸器(qi)的(de)固定內六角(jiao)螺釘擰(ning)下來，再(zai)輕輕把聯(lian)軸器(qi)的(de)一半從軸上(shang)慢(man)慢(man)拉(la)下，注意不要掉了(le)，再(zai)用梅(mei)花(hua)扳手擰(ning)下泵(beng)(beng)軸吊(diao)緊螺栓和擋(dang)塊，讓葉(xie)輪慢(man)慢(man)下沉至泵(beng)(beng)體(ti)，然(ran)后拆下另外(wai)一半聯(lian)軸器(qi)，拿下泵(beng)(beng)軸擋(dang)圈。

　　拆卸隴南機械密封：抓住(zhu)密封(feng)彈簧(huang)順(shun)著泵軸往上提，就能(neng)拆(chai)下來(lai)了。

　　拆卸(xie)并清洗軸承(cheng)座(zuo)：先輕(qing)輕(qing)松動(dong)一下(xia)軸承(cheng)座(zuo)后(hou)用(yong)拆卸(xie)螺栓(shuan)頂起軸承(cheng)座(zuo)，并且沿著泵軸往上提(ti)而卸(xie)下(xia)，再用(yong)噴氣(qi)燃料清洗軸承(cheng)及座(zuo)，裝(zhuang)前晾干(gan)并涂抹少許20號機械油用(yong)來潤滑保(bao)護(hu)。

　　拆密封座：擰下(xia)密封座壓緊螺母，輕輕卸下(xia)密封座并清洗。

　　隴南機械密封裝配(pei)：在動、靜(jing)環鏡(jing)面上涂一層潔凈的20號潤滑油，導軸承座(zuo)也抹上潤滑油，先把靜(jing)環輕(qing)輕(qing)定位裝入導軸承座(zuo)，再(zai)在泵軸上抹上潤滑油，把動環部(bu)分(fen)(fen)輕(qing)輕(qing)裝入泵軸上，用手輕(qing)推密封環應能伸縮(suo)自如，注意(yi)動、靜(jing)環部(bu)分(fen)(fen)的防轉部(bu)位需裝配(pei)到位。

　　裝(zhuang)(zhuang)聯軸(zhou)器(qi)：在(zai)(zai)電機軸(zhou)頭上(shang)(shang)裝(zhuang)(zhuang)上(shang)(shang)擋(dang)圈，裝(zhuang)(zhuang)上(shang)(shang)一半聯軸(zhou)器(qi)，再在(zai)(zai)泵(beng)軸(zhou)端和聯軸(zhou)器(qi)槽(cao)內(nei)裝(zhuang)(zhuang)上(shang)(shang)擋(dang)塊并用梅花扳手擰(ning)緊螺栓；再裝(zhuang)(zhuang)上(shang)(shang)另一半聯軸(zhou)器(qi)擰(ning)上(shang)(shang)內(nei)六角(jiao)螺釘。安裝(zhuang)(zhuang)聯軸(zhou)器(qi)正確(que)的檢(jian)查(cha)(cha)要求：對分式聯軸(zhou)器(qi)上(shang)(shang)下間(jian)隙需要均勻，用手盤動聯軸(zhou)器(qi)幾圈檢(jian)查(cha)(cha)轉動的靈活性。

　　裝(zhuang)(zhuang)密封(feng)座(zuo)：先(xian)將密封(feng)座(zuo)裝(zhuang)(zhuang)入(ru)橡膠油封(feng)，再把密封(feng)座(zuo)裝(zhuang)(zhuang)入(ru)泵蓋(gai)并壓(ya)(ya)在軸承座(zuo)上(shang)(shang)，擰緊(jin)(jin)螺(luo)母(mu)，確(que)保所有安裝(zhuang)(zhuang)螺(luo)釘緊(jin)(jin)固(gu)。當安裝(zhuang)(zhuang)螺(luo)釘被用(yong)(yong)(yong)作密封(feng)與軸之間的(de)驅動時(shi)，軸應(ying)打埋頭孔來加固(gu)連接(jie)，緊(jin)(jin)固(gu)壓(ya)(ya)蓋(gai)螺(luo)栓時(shi)應(ying)該平(ping)穩緊(jin)(jin)固(gu)，并且不要使壓(ya)(ya)蓋(gai)受彈力(li)。在可能的(de)地方使用(yong)(yong)(yong)4個(ge)以上(shang)(shang)螺(luo)釘的(de)等間距(ju)壓(ya)(ya)蓋(gai)，緊(jin)(jin)固(gu)壓(ya)(ya)蓋(gai)螺(luo)栓時(shi)，用(yong)(yong)(yong)塞尺檢查軸與壓(ya)(ya)蓋(gai)之間的(de)間隙，這在密封(feng)腔對壓(ya)(ya)蓋(gai)不導(dao)向時(shi)，顯得特(te)別重要，因為壓(ya)(ya)蓋(gai)必須對中。
