臨渭機械密封利用機(ji)械方式(shi)傳(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)力(li)和(he)運動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)的(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)，機(ji)械傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)在機(ji)械工程中應(ying)用非常廣泛，有多種形式(shi)，主要(yao)包(bao)括皮帶(dai)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、蝸桿蝸輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)齒(chi)條(tiao)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)和(he)螺旋傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)等(deng)。齒(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)能(neng)(neng)夠用于大(da)(da)功率的(de)場合，傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)比準確，但一般(ban)要(yao)求較(jiao)(jiao)高的(de)制造精(jing)(jing)度和(he)安裝精(jing)(jing)度。還(huan)有一類是靠(kao)機(ji)件間的(de)摩(mo)擦力(li)傳(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)力(li)和(he)運動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)的(de)摩(mo)擦傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)，包(bao)括帶(dai)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、繩(sheng)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)和(he)摩(mo)擦輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)等(deng)。摩(mo)擦傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)容易(yi)實現無(wu)級(ji)變速(su)，可(ke)以適(shi)應(ying)軸間距較(jiao)(jiao)大(da)(da)的(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)場合，而過載打滑還(huan)能(neng)(neng)起到緩沖和(he)保(bao)護(hu)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)裝置的(de)作用，但這種傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)一般(ban)不能(neng)(neng)用于大(da)(da)功率的(de)場合，也不能(neng)(neng)保(bao)證準確的(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)比。

　　傳動形式多，但是臨渭機械密封的更換工作(zuo)大同小異，首先(xian)拆(chai)前需確認電機處于檢修狀態，擰下加油螺塞，用吸(xi)管把(ba)密封座腔內的潤滑油吸(xi)出(chu)。準備(bei)好放置泵零(ling)件的工作(zuo)臺及拆(chai)裝(zhuang)工具，切勿任意亂(luan)放亂(luan)用，避(bi)免碰(peng)壞泵的零(ling)部件。

　　拆對(dui)分式聯(lian)(lian)軸(zhou)(zhou)(zhou)器：先把(ba)聯(lian)(lian)軸(zhou)(zhou)(zhou)器的固定內六角螺釘(ding)擰下(xia)來(lai)，再輕(qing)輕(qing)把(ba)聯(lian)(lian)軸(zhou)(zhou)(zhou)器的一半從軸(zhou)(zhou)(zhou)上(shang)慢慢拉下(xia)，注意不要掉了，再用梅花扳(ban)手擰下(xia)泵軸(zhou)(zhou)(zhou)吊(diao)緊螺栓和擋(dang)塊，讓葉輪慢慢下(xia)沉至泵體，然后(hou)拆下(xia)另外一半聯(lian)(lian)軸(zhou)(zhou)(zhou)器，拿(na)下(xia)泵軸(zhou)(zhou)(zhou)擋(dang)圈。

　　拆卸臨渭機械密封：抓住密封彈簧順著泵(beng)軸往上提，就能拆下來了。

　　拆卸并清洗(xi)軸承(cheng)座：先(xian)輕輕松動一(yi)下軸承(cheng)座后用拆卸螺栓頂起軸承(cheng)座，并且沿著泵軸往上提而卸下，再用噴氣燃料清洗(xi)軸承(cheng)及座，裝前晾干并涂抹少許(xu)20號機(ji)械油用來潤滑保護。

　　拆密封(feng)座：擰下密封(feng)座壓緊螺母，輕輕卸下密封(feng)座并清(qing)洗。

　　臨渭機械密封裝(zhuang)(zhuang)(zhuang)配：在動(dong)(dong)、靜環(huan)(huan)鏡面上(shang)涂一層潔凈(jing)的20號潤(run)滑(hua)油(you)，導(dao)軸承座(zuo)也抹(mo)上(shang)潤(run)滑(hua)油(you)，先(xian)把(ba)靜環(huan)(huan)輕(qing)輕(qing)定位(wei)裝(zhuang)(zhuang)(zhuang)入導(dao)軸承座(zuo)，再在泵(beng)軸上(shang)抹(mo)上(shang)潤(run)滑(hua)油(you)，把(ba)動(dong)(dong)環(huan)(huan)部(bu)(bu)分輕(qing)輕(qing)裝(zhuang)(zhuang)(zhuang)入泵(beng)軸上(shang)，用手(shou)輕(qing)推密封環(huan)(huan)應能伸縮(suo)自如，注(zhu)意動(dong)(dong)、靜環(huan)(huan)部(bu)(bu)分的防轉部(bu)(bu)位(wei)需裝(zhuang)(zhuang)(zhuang)配到位(wei)。

　　裝(zhuang)聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)：在(zai)(zai)電機軸(zhou)(zhou)(zhou)頭上(shang)(shang)裝(zhuang)上(shang)(shang)擋(dang)圈，裝(zhuang)上(shang)(shang)一(yi)(yi)半聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)，再在(zai)(zai)泵軸(zhou)(zhou)(zhou)端和聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)槽內裝(zhuang)上(shang)(shang)擋(dang)塊(kuai)并用梅(mei)花扳手擰緊螺栓(shuan)；再裝(zhuang)上(shang)(shang)另一(yi)(yi)半聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)擰上(shang)(shang)內六角螺釘。安裝(zhuang)聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)正(zheng)確的(de)檢(jian)查要求：對分式(shi)聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)上(shang)(shang)下間(jian)隙需要均勻，用手盤動聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)幾圈檢(jian)查轉動的(de)靈活性(xing)。

　　裝(zhuang)(zhuang)密封(feng)座(zuo)：先(xian)將(jiang)密封(feng)座(zuo)裝(zhuang)(zhuang)入橡膠油封(feng)，再把密封(feng)座(zuo)裝(zhuang)(zhuang)入泵蓋(gai)并壓(ya)(ya)(ya)在(zai)(zai)軸(zhou)(zhou)承座(zuo)上(shang)(shang)，擰緊(jin)(jin)螺(luo)母，確保所(suo)有(you)安裝(zhuang)(zhuang)螺(luo)釘緊(jin)(jin)固(gu)。當(dang)安裝(zhuang)(zhuang)螺(luo)釘被(bei)用作密封(feng)與(yu)(yu)軸(zhou)(zhou)之(zhi)間的(de)驅(qu)動時(shi)，軸(zhou)(zhou)應打埋頭孔來加固(gu)連(lian)接，緊(jin)(jin)固(gu)壓(ya)(ya)(ya)蓋(gai)螺(luo)栓時(shi)應該平穩緊(jin)(jin)固(gu)，并且(qie)不要(yao)使壓(ya)(ya)(ya)蓋(gai)受彈力。在(zai)(zai)可能的(de)地方使用4個(ge)以上(shang)(shang)螺(luo)釘的(de)等間距壓(ya)(ya)(ya)蓋(gai)，緊(jin)(jin)固(gu)壓(ya)(ya)(ya)蓋(gai)螺(luo)栓時(shi)，用塞尺檢查軸(zhou)(zhou)與(yu)(yu)壓(ya)(ya)(ya)蓋(gai)之(zhi)間的(de)間隙，這在(zai)(zai)密封(feng)腔對壓(ya)(ya)(ya)蓋(gai)不導向(xiang)時(shi)，顯得特別重要(yao)，因為(wei)壓(ya)(ya)(ya)蓋(gai)必須對中。
