小金機械密封利用(yong)(yong)機械(xie)(xie)方式傳遞動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)力和運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)的(de)傳動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)，機械(xie)(xie)傳動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)在機械(xie)(xie)工程中應用(yong)(yong)非常(chang)廣泛，有多(duo)種(zhong)形(xing)式，主要包括(kuo)皮帶傳動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)傳動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、鏈傳動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、蝸桿蝸輪(lun)傳動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)齒(chi)條傳動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)和螺(luo)旋傳動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)等(deng)(deng)。齒(chi)輪(lun)傳動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)能夠(gou)用(yong)(yong)于(yu)大(da)(da)功率的(de)場(chang)合(he)，傳動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)比準(zhun)確，但一般(ban)要求較高的(de)制(zhi)造精度和安裝精度。還(huan)有一類是(shi)靠機件間的(de)摩(mo)擦(ca)力傳遞動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)力和運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)的(de)摩(mo)擦(ca)傳動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)，包括(kuo)帶傳動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、繩(sheng)傳動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)和摩(mo)擦(ca)輪(lun)傳動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)等(deng)(deng)。摩(mo)擦(ca)傳動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)容(rong)易實現無級(ji)變(bian)速(su)，可以(yi)適(shi)應軸間距(ju)較大(da)(da)的(de)傳動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)場(chang)合(he)，而過載打滑還(huan)能起到緩(huan)沖和保護傳動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)裝置的(de)作用(yong)(yong)，但這種(zhong)傳動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)一般(ban)不能用(yong)(yong)于(yu)大(da)(da)功率的(de)場(chang)合(he)，也不能保證準(zhun)確的(de)傳動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)比。

　　傳動形式多，但是小金機械密封的(de)更換工作大同(tong)小異，首先拆(chai)前需確認電機處于(yu)檢修狀(zhuang)態，擰(ning)下加油螺塞，用吸管(guan)把密封座腔內的(de)潤滑(hua)油吸出(chu)。準備(bei)好(hao)放置泵(beng)零(ling)件(jian)的(de)工作臺及拆(chai)裝工具，切勿任(ren)意(yi)亂放亂用，避免碰壞泵(beng)的(de)零(ling)部件(jian)。

　　拆(chai)(chai)對分(fen)式聯(lian)軸(zhou)器：先把聯(lian)軸(zhou)器的固定(ding)內六(liu)角螺(luo)釘擰(ning)(ning)下來，再輕(qing)(qing)輕(qing)(qing)把聯(lian)軸(zhou)器的一(yi)半(ban)從軸(zhou)上慢慢拉下，注意(yi)不要掉了，再用(yong)梅花扳(ban)手擰(ning)(ning)下泵(beng)軸(zhou)吊緊(jin)螺(luo)栓和(he)擋塊(kuai)，讓葉輪慢慢下沉(chen)至泵(beng)體，然后拆(chai)(chai)下另外一(yi)半(ban)聯(lian)軸(zhou)器，拿(na)下泵(beng)軸(zhou)擋圈。

　　拆卸小金機械密封：抓住(zhu)密封彈簧順著泵軸往上提，就能拆(chai)下來(lai)了。

　　拆卸并(bing)(bing)清洗(xi)軸(zhou)承(cheng)(cheng)座(zuo)：先輕輕松動(dong)一下軸(zhou)承(cheng)(cheng)座(zuo)后(hou)用拆卸螺栓頂(ding)起軸(zhou)承(cheng)(cheng)座(zuo)，并(bing)(bing)且沿著泵軸(zhou)往上提(ti)而卸下，再用噴氣(qi)燃料清洗(xi)軸(zhou)承(cheng)(cheng)及(ji)座(zuo)，裝前晾干并(bing)(bing)涂抹少許(xu)20號(hao)機械油用來潤滑(hua)保(bao)護(hu)。

　　拆密封(feng)(feng)座(zuo)(zuo)：擰下密封(feng)(feng)座(zuo)(zuo)壓緊(jin)螺(luo)母，輕輕卸下密封(feng)(feng)座(zuo)(zuo)并清洗。

　　小金機械密封裝配(pei)：在動(dong)、靜環鏡(jing)面(mian)上(shang)涂一層(ceng)潔凈的20號潤滑油(you)，導軸承(cheng)座也抹(mo)上(shang)潤滑油(you)，先把靜環輕(qing)輕(qing)定位裝入導軸承(cheng)座，再在泵軸上(shang)抹(mo)上(shang)潤滑油(you)，把動(dong)環部分(fen)輕(qing)輕(qing)裝入泵軸上(shang)，用手輕(qing)推密封(feng)環應(ying)能(neng)伸縮(suo)自如，注意動(dong)、靜環部分(fen)的防轉部位需裝配(pei)到位。

　　裝(zhuang)聯(lian)軸器：在電機(ji)軸頭上(shang)裝(zhuang)上(shang)擋圈(quan)(quan)，裝(zhuang)上(shang)一半(ban)(ban)聯(lian)軸器，再在泵軸端和聯(lian)軸器槽(cao)內裝(zhuang)上(shang)擋塊并用梅(mei)花扳手(shou)擰緊螺栓；再裝(zhuang)上(shang)另一半(ban)(ban)聯(lian)軸器擰上(shang)內六角螺釘。安裝(zhuang)聯(lian)軸器正(zheng)確(que)的(de)檢查(cha)要(yao)求：對分式聯(lian)軸器上(shang)下間隙需要(yao)均勻，用手(shou)盤(pan)動聯(lian)軸器幾圈(quan)(quan)檢查(cha)轉動的(de)靈活性。

　　裝密封(feng)(feng)(feng)座(zuo)(zuo)：先將密封(feng)(feng)(feng)座(zuo)(zuo)裝入橡膠(jiao)油封(feng)(feng)(feng)，再(zai)把(ba)密封(feng)(feng)(feng)座(zuo)(zuo)裝入泵蓋(gai)并壓(ya)(ya)(ya)在(zai)軸承座(zuo)(zuo)上，擰(ning)緊(jin)螺(luo)母，確(que)保所有安裝螺(luo)釘緊(jin)固(gu)(gu)。當安裝螺(luo)釘被(bei)用(yong)作密封(feng)(feng)(feng)與軸之(zhi)間(jian)的(de)驅動時(shi)，軸應(ying)打埋頭孔來加(jia)固(gu)(gu)連接，緊(jin)固(gu)(gu)壓(ya)(ya)(ya)蓋(gai)螺(luo)栓時(shi)應(ying)該平穩緊(jin)固(gu)(gu)，并且不(bu)(bu)要使(shi)壓(ya)(ya)(ya)蓋(gai)受(shou)彈力(li)。在(zai)可能(neng)的(de)地方使(shi)用(yong)4個以(yi)上螺(luo)釘的(de)等間(jian)距壓(ya)(ya)(ya)蓋(gai)，緊(jin)固(gu)(gu)壓(ya)(ya)(ya)蓋(gai)螺(luo)栓時(shi)，用(yong)塞(sai)尺檢(jian)查軸與壓(ya)(ya)(ya)蓋(gai)之(zhi)間(jian)的(de)間(jian)隙，這在(zai)密封(feng)(feng)(feng)腔對(dui)壓(ya)(ya)(ya)蓋(gai)不(bu)(bu)導向(xiang)時(shi)，顯得特(te)別重要，因為壓(ya)(ya)(ya)蓋(gai)必須對(dui)中。
