相城機械密封利(li)用機械方(fang)式(shi)傳(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)力(li)和(he)(he)運動(dong)(dong)(dong)(dong)(dong)的(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，機械傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)在機械工程中應用非常廣(guang)泛，有(you)(you)多種形式(shi)，主要包括(kuo)皮帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)(chi)(chi)輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、蝸桿蝸輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)(chi)(chi)輪齒(chi)(chi)(chi)條傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)(he)螺旋傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等。齒(chi)(chi)(chi)輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)能(neng)(neng)夠用于大(da)功率的(de)(de)場(chang)合，傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比準確，但一(yi)般要求較高的(de)(de)制(zhi)造(zao)精度和(he)(he)安裝(zhuang)精度。還(huan)有(you)(you)一(yi)類是靠(kao)機件間的(de)(de)摩(mo)擦(ca)力(li)傳(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)力(li)和(he)(he)運動(dong)(dong)(dong)(dong)(dong)的(de)(de)摩(mo)擦(ca)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，包括(kuo)帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)(he)摩(mo)擦(ca)輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等。摩(mo)擦(ca)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)容(rong)易實現無級變速，可以適應軸間距(ju)較大(da)的(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)場(chang)合，而過載打滑還(huan)能(neng)(neng)起到緩沖和(he)(he)保(bao)護(hu)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)裝(zhuang)置的(de)(de)作用，但這種傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)一(yi)般不能(neng)(neng)用于大(da)功率的(de)(de)場(chang)合，也不能(neng)(neng)保(bao)證準確的(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比。

　　傳動形式多，但是相城機械密封的更換工作大同小異，首先拆前需確認(ren)電機處(chu)于(yu)檢(jian)修狀態，擰下加油螺塞，用吸管把密封(feng)座腔(qiang)內的潤(run)滑油吸出(chu)。準備好放(fang)置泵零件的工作臺及拆裝(zhuang)工具，切(qie)勿任(ren)意亂放(fang)亂用，避(bi)免碰壞泵的零部件。

　　拆對分式聯(lian)(lian)軸(zhou)器(qi)(qi)：先把聯(lian)(lian)軸(zhou)器(qi)(qi)的固定內六角螺(luo)(luo)釘(ding)擰下(xia)來，再輕輕把聯(lian)(lian)軸(zhou)器(qi)(qi)的一半從軸(zhou)上(shang)慢慢拉下(xia)，注意(yi)不要(yao)掉(diao)了(le)，再用梅花扳手擰下(xia)泵軸(zhou)吊緊螺(luo)(luo)栓和擋塊，讓(rang)葉輪慢慢下(xia)沉至泵體，然(ran)后拆下(xia)另(ling)外一半聯(lian)(lian)軸(zhou)器(qi)(qi)，拿下(xia)泵軸(zhou)擋圈(quan)。

　　拆卸相城機械密封：抓住密封彈簧順著泵軸往上(shang)提，就能(neng)拆下來了。

　　拆卸(xie)并清洗軸承(cheng)座：先輕(qing)(qing)輕(qing)(qing)松動一下軸承(cheng)座后用拆卸(xie)螺栓頂起軸承(cheng)座，并且沿(yan)著泵軸往上(shang)提而卸(xie)下，再(zai)用噴氣燃料清洗軸承(cheng)及座，裝前晾(liang)干并涂抹少許20號機械油用來潤滑保護。

　　拆密封座(zuo)：擰下密封座(zuo)壓緊螺母，輕輕卸下密封座(zuo)并清洗。

　　相城機械密封裝配：在動、靜(jing)環(huan)(huan)鏡面上(shang)涂一層潔凈的20號潤滑(hua)(hua)油，導(dao)軸承座(zuo)也抹上(shang)潤滑(hua)(hua)油，先把(ba)靜(jing)環(huan)(huan)輕(qing)輕(qing)定位裝入(ru)(ru)導(dao)軸承座(zuo)，再在泵軸上(shang)抹上(shang)潤滑(hua)(hua)油，把(ba)動環(huan)(huan)部分輕(qing)輕(qing)裝入(ru)(ru)泵軸上(shang)，用手輕(qing)推密封環(huan)(huan)應(ying)能伸(shen)縮自如，注意(yi)動、靜(jing)環(huan)(huan)部分的防轉部位需裝配到位。

　　裝(zhuang)聯(lian)(lian)軸器(qi)：在電機軸頭上裝(zhuang)上擋圈，裝(zhuang)上一(yi)半聯(lian)(lian)軸器(qi)，再(zai)在泵(beng)軸端和聯(lian)(lian)軸器(qi)槽內(nei)裝(zhuang)上擋塊并用梅(mei)花扳手(shou)擰(ning)緊螺(luo)栓；再(zai)裝(zhuang)上另(ling)一(yi)半聯(lian)(lian)軸器(qi)擰(ning)上內(nei)六角螺(luo)釘(ding)。安裝(zhuang)聯(lian)(lian)軸器(qi)正確(que)的檢(jian)查要求：對分式聯(lian)(lian)軸器(qi)上下間隙需(xu)要均勻，用手(shou)盤(pan)動聯(lian)(lian)軸器(qi)幾圈檢(jian)查轉(zhuan)動的靈活性。

　　裝密(mi)(mi)封(feng)(feng)(feng)座：先(xian)將密(mi)(mi)封(feng)(feng)(feng)座裝入(ru)橡(xiang)膠(jiao)油封(feng)(feng)(feng)，再(zai)把密(mi)(mi)封(feng)(feng)(feng)座裝入(ru)泵蓋(gai)并壓(ya)(ya)在軸(zhou)承座上(shang)，擰緊(jin)螺(luo)(luo)母(mu)，確保(bao)所(suo)有(you)安裝螺(luo)(luo)釘(ding)(ding)緊(jin)固(gu)。當安裝螺(luo)(luo)釘(ding)(ding)被用作密(mi)(mi)封(feng)(feng)(feng)與軸(zhou)之(zhi)(zhi)間的(de)(de)驅(qu)動(dong)時，軸(zhou)應打(da)埋頭孔(kong)來加固(gu)連接，緊(jin)固(gu)壓(ya)(ya)蓋(gai)螺(luo)(luo)栓時應該平穩緊(jin)固(gu)，并且不要(yao)使壓(ya)(ya)蓋(gai)受(shou)彈力。在可能的(de)(de)地(di)方使用4個以(yi)上(shang)螺(luo)(luo)釘(ding)(ding)的(de)(de)等(deng)間距壓(ya)(ya)蓋(gai)，緊(jin)固(gu)壓(ya)(ya)蓋(gai)螺(luo)(luo)栓時，用塞尺檢查軸(zhou)與壓(ya)(ya)蓋(gai)之(zhi)(zhi)間的(de)(de)間隙，這在密(mi)(mi)封(feng)(feng)(feng)腔對壓(ya)(ya)蓋(gai)不導向時，顯(xian)得特別重要(yao)，因為壓(ya)(ya)蓋(gai)必須對中。
