城固機械密封利(li)用(yong)機(ji)械方(fang)式傳(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)力和(he)運動(dong)(dong)(dong)(dong)的(de)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)，機(ji)械傳(chuan)(chuan)動(dong)(dong)(dong)(dong)在(zai)機(ji)械工程中應用(yong)非(fei)常廣泛，有多種形式，主(zhu)要(yao)包括(kuo)皮帶(dai)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒(chi)輪傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、蝸(gua)桿(gan)蝸(gua)輪傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒(chi)輪齒(chi)條傳(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)螺旋傳(chuan)(chuan)動(dong)(dong)(dong)(dong)等。齒(chi)輪傳(chuan)(chuan)動(dong)(dong)(dong)(dong)能(neng)夠用(yong)于大(da)功率的(de)場合(he)，傳(chuan)(chuan)動(dong)(dong)(dong)(dong)比準(zhun)確(que)，但一般要(yao)求較高的(de)制造(zao)精度(du)和(he)安裝精度(du)。還有一類是靠機(ji)件間的(de)摩擦(ca)力傳(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)力和(he)運動(dong)(dong)(dong)(dong)的(de)摩擦(ca)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)，包括(kuo)帶(dai)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)摩擦(ca)輪傳(chuan)(chuan)動(dong)(dong)(dong)(dong)等。摩擦(ca)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)容易(yi)實現無(wu)級變(bian)速，可以(yi)適應軸(zhou)間距較大(da)的(de)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)場合(he)，而(er)過載打滑還能(neng)起到緩(huan)沖和(he)保護傳(chuan)(chuan)動(dong)(dong)(dong)(dong)裝置(zhi)的(de)作用(yong)，但這種傳(chuan)(chuan)動(dong)(dong)(dong)(dong)一般不能(neng)用(yong)于大(da)功率的(de)場合(he)，也(ye)不能(neng)保證準(zhun)確(que)的(de)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)比。

　　傳動形式多，但是城固機械密封的更換(huan)工作(zuo)大同小(xiao)異，首先(xian)拆(chai)前需確認電機處于檢(jian)修狀態，擰下加油螺塞，用(yong)吸管(guan)把密封座腔內的潤滑油吸出。準備好放置泵零(ling)件的工作(zuo)臺及拆(chai)裝(zhuang)工具，切(qie)勿(wu)任(ren)意(yi)亂(luan)放亂(luan)用(yong)，避免碰壞泵的零(ling)部件。

　　拆(chai)對分式(shi)聯(lian)軸(zhou)器(qi)：先把(ba)聯(lian)軸(zhou)器(qi)的固定內六角螺釘擰下(xia)來，再(zai)輕(qing)輕(qing)把(ba)聯(lian)軸(zhou)器(qi)的一半(ban)(ban)從軸(zhou)上慢(man)慢(man)拉下(xia)，注意不要掉了，再(zai)用梅花扳手擰下(xia)泵(beng)軸(zhou)吊(diao)緊螺栓和(he)擋(dang)塊，讓葉(xie)輪慢(man)慢(man)下(xia)沉至泵(beng)體，然(ran)后拆(chai)下(xia)另(ling)外一半(ban)(ban)聯(lian)軸(zhou)器(qi)，拿下(xia)泵(beng)軸(zhou)擋(dang)圈。

　　拆卸城固機械密封：抓住密封(feng)彈簧順著泵軸往上提，就(jiu)能(neng)拆下來(lai)了。

　　拆(chai)卸(xie)(xie)(xie)并(bing)清(qing)洗(xi)軸(zhou)(zhou)承(cheng)座：先輕輕松動(dong)一下軸(zhou)(zhou)承(cheng)座后(hou)用(yong)拆(chai)卸(xie)(xie)(xie)螺(luo)栓頂(ding)起(qi)軸(zhou)(zhou)承(cheng)座，并(bing)且沿著(zhu)泵(beng)軸(zhou)(zhou)往上提而卸(xie)(xie)(xie)下，再用(yong)噴氣燃(ran)料清(qing)洗(xi)軸(zhou)(zhou)承(cheng)及(ji)座，裝(zhuang)前(qian)晾干(gan)并(bing)涂抹少許20號機械油用(yong)來潤滑保護。

　　拆密封(feng)座(zuo)(zuo)：擰下(xia)密封(feng)座(zuo)(zuo)壓(ya)緊螺母(mu)，輕輕卸下(xia)密封(feng)座(zuo)(zuo)并(bing)清洗。

　　城固機械密封裝(zhuang)(zhuang)配：在(zai)動(dong)(dong)、靜環(huan)鏡面上(shang)(shang)涂一層(ceng)潔凈(jing)的20號潤滑油(you)，導(dao)軸(zhou)承座也抹上(shang)(shang)潤滑油(you)，先把(ba)靜環(huan)輕(qing)輕(qing)定位(wei)裝(zhuang)(zhuang)入導(dao)軸(zhou)承座，再在(zai)泵軸(zhou)上(shang)(shang)抹上(shang)(shang)潤滑油(you)，把(ba)動(dong)(dong)環(huan)部(bu)分輕(qing)輕(qing)裝(zhuang)(zhuang)入泵軸(zhou)上(shang)(shang)，用手輕(qing)推(tui)密封(feng)環(huan)應能伸縮自如，注意動(dong)(dong)、靜環(huan)部(bu)分的防轉部(bu)位(wei)需裝(zhuang)(zhuang)配到位(wei)。

　　裝聯(lian)軸(zhou)(zhou)器(qi)：在電機軸(zhou)(zhou)頭上(shang)裝上(shang)擋(dang)圈，裝上(shang)一(yi)半聯(lian)軸(zhou)(zhou)器(qi)，再(zai)在泵(beng)軸(zhou)(zhou)端和聯(lian)軸(zhou)(zhou)器(qi)槽內裝上(shang)擋(dang)塊(kuai)并用梅花扳手(shou)擰(ning)緊螺(luo)栓(shuan)；再(zai)裝上(shang)另一(yi)半聯(lian)軸(zhou)(zhou)器(qi)擰(ning)上(shang)內六角螺(luo)釘。安(an)裝聯(lian)軸(zhou)(zhou)器(qi)正確(que)的檢(jian)查要(yao)求：對分式聯(lian)軸(zhou)(zhou)器(qi)上(shang)下(xia)間隙(xi)需要(yao)均勻，用手(shou)盤動(dong)聯(lian)軸(zhou)(zhou)器(qi)幾圈檢(jian)查轉動(dong)的靈活性。

　　裝(zhuang)密封(feng)座：先將密封(feng)座裝(zhuang)入橡(xiang)膠油(you)封(feng)，再把密封(feng)座裝(zhuang)入泵蓋(gai)并(bing)壓(ya)(ya)(ya)在軸承座上(shang)(shang)，擰緊螺母，確保(bao)所有(you)安(an)(an)裝(zhuang)螺釘(ding)緊固。當安(an)(an)裝(zhuang)螺釘(ding)被用作密封(feng)與軸之間(jian)(jian)的驅動時，軸應打(da)埋(mai)頭孔來加固連接(jie)，緊固壓(ya)(ya)(ya)蓋(gai)螺栓(shuan)時應該平穩(wen)緊固，并(bing)且不要使壓(ya)(ya)(ya)蓋(gai)受彈力。在可能的地方使用4個(ge)以上(shang)(shang)螺釘(ding)的等間(jian)(jian)距(ju)壓(ya)(ya)(ya)蓋(gai)，緊固壓(ya)(ya)(ya)蓋(gai)螺栓(shuan)時，用塞尺(chi)檢查軸與壓(ya)(ya)(ya)蓋(gai)之間(jian)(jian)的間(jian)(jian)隙，這在密封(feng)腔(qiang)對壓(ya)(ya)(ya)蓋(gai)不導向時，顯得特別重要，因為壓(ya)(ya)(ya)蓋(gai)必須對中(zhong)。
