貢山機械密封利用機械方式傳(chuan)(chuan)(chuan)(chuan)(chuan)遞(di)(di)動(dong)(dong)(dong)力和(he)運動(dong)(dong)(dong)的(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)，機械傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)在機械工程中應用非常廣泛，有多種形式，主要包括皮帶傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、齒輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、蝸(gua)桿(gan)蝸(gua)輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、齒輪(lun)齒條(tiao)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)和(he)螺(luo)旋傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)等(deng)。齒輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)能(neng)夠用于大功(gong)率(lv)的(de)場(chang)合，傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)比(bi)準確，但一(yi)般(ban)要求(qiu)較高的(de)制造精度(du)和(he)安裝(zhuang)精度(du)。還有一(yi)類是(shi)靠機件間(jian)的(de)摩擦(ca)力傳(chuan)(chuan)(chuan)(chuan)(chuan)遞(di)(di)動(dong)(dong)(dong)力和(he)運動(dong)(dong)(dong)的(de)摩擦(ca)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)，包括帶傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)和(he)摩擦(ca)輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)等(deng)。摩擦(ca)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)容易(yi)實現無級變速，可以適應軸間(jian)距較大的(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)場(chang)合，而過載打滑(hua)還能(neng)起(qi)到緩沖和(he)保護傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)裝(zhuang)置的(de)作用，但這種傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)一(yi)般(ban)不能(neng)用于大功(gong)率(lv)的(de)場(chang)合，也不能(neng)保證準確的(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)比(bi)。

　　傳動形式多，但是貢山機械密封的(de)(de)更(geng)換工作(zuo)大同小異(yi)，首先拆(chai)前(qian)需確認(ren)電(dian)機處于(yu)檢修(xiu)狀態，擰下加油螺塞，用(yong)吸管把密封座(zuo)腔內的(de)(de)潤滑(hua)油吸出。準備好放(fang)置泵(beng)零件的(de)(de)工作(zuo)臺及(ji)拆(chai)裝工具(ju)，切勿(wu)任意亂(luan)(luan)放(fang)亂(luan)(luan)用(yong)，避免碰(peng)壞(huai)泵(beng)的(de)(de)零部件。

　　拆對分式(shi)聯(lian)軸(zhou)(zhou)(zhou)器(qi)：先(xian)把(ba)(ba)聯(lian)軸(zhou)(zhou)(zhou)器(qi)的固定內六角螺釘(ding)擰下來，再輕(qing)輕(qing)把(ba)(ba)聯(lian)軸(zhou)(zhou)(zhou)器(qi)的一半從軸(zhou)(zhou)(zhou)上慢慢拉下，注意不(bu)要掉了，再用梅花扳手擰下泵軸(zhou)(zhou)(zhou)吊緊(jin)螺栓和擋(dang)塊，讓葉輪慢慢下沉至泵體，然(ran)后拆下另(ling)外一半聯(lian)軸(zhou)(zhou)(zhou)器(qi)，拿下泵軸(zhou)(zhou)(zhou)擋(dang)圈(quan)。

　　拆卸貢山機械密封：抓(zhua)住密封彈(dan)簧(huang)順(shun)著泵(beng)軸往上提，就(jiu)能(neng)拆下來了。

　　拆(chai)卸并(bing)(bing)清洗軸承座：先輕(qing)輕(qing)松(song)動一下軸承座后用拆(chai)卸螺栓頂起軸承座，并(bing)(bing)且沿著泵軸往上提而卸下，再用噴氣燃(ran)料(liao)清洗軸承及座，裝前(qian)晾干并(bing)(bing)涂抹少許(xu)20號(hao)機械油(you)用來潤滑(hua)保護。

　　拆密封座：擰下密封座壓(ya)緊螺(luo)母(mu)，輕輕卸下密封座并清(qing)洗。

　　貢山機械密封裝配(pei)：在(zai)動、靜(jing)環(huan)鏡面(mian)上涂一層潔(jie)凈的20號潤滑(hua)油，導軸承座也(ye)抹上潤滑(hua)油，先把靜(jing)環(huan)輕(qing)輕(qing)定(ding)位裝入(ru)導軸承座，再在(zai)泵軸上抹上潤滑(hua)油，把動環(huan)部分輕(qing)輕(qing)裝入(ru)泵軸上，用手輕(qing)推密封(feng)環(huan)應(ying)能伸(shen)縮自如，注意動、靜(jing)環(huan)部分的防轉部位需裝配(pei)到位。

　　裝聯軸(zhou)(zhou)器(qi)(qi)：在(zai)電機軸(zhou)(zhou)頭上(shang)(shang)裝上(shang)(shang)擋圈，裝上(shang)(shang)一(yi)半聯軸(zhou)(zhou)器(qi)(qi)，再在(zai)泵軸(zhou)(zhou)端和聯軸(zhou)(zhou)器(qi)(qi)槽內裝上(shang)(shang)擋塊(kuai)并用梅花(hua)扳手擰緊螺栓；再裝上(shang)(shang)另一(yi)半聯軸(zhou)(zhou)器(qi)(qi)擰上(shang)(shang)內六(liu)角螺釘。安裝聯軸(zhou)(zhou)器(qi)(qi)正確的檢查要求：對分式聯軸(zhou)(zhou)器(qi)(qi)上(shang)(shang)下(xia)間隙需要均勻，用手盤動聯軸(zhou)(zhou)器(qi)(qi)幾圈檢查轉動的靈活(huo)性。

　　裝(zhuang)密(mi)封(feng)(feng)座：先將密(mi)封(feng)(feng)座裝(zhuang)入橡膠油封(feng)(feng)，再把密(mi)封(feng)(feng)座裝(zhuang)入泵(beng)蓋(gai)并壓(ya)(ya)在(zai)軸承座上(shang)，擰緊(jin)(jin)螺母，確保(bao)所(suo)有(you)安(an)裝(zhuang)螺釘緊(jin)(jin)固(gu)(gu)。當安(an)裝(zhuang)螺釘被用(yong)作(zuo)密(mi)封(feng)(feng)與軸之間的驅動時(shi)，軸應打埋頭孔來加固(gu)(gu)連接，緊(jin)(jin)固(gu)(gu)壓(ya)(ya)蓋(gai)螺栓時(shi)應該(gai)平穩緊(jin)(jin)固(gu)(gu)，并且不(bu)要使壓(ya)(ya)蓋(gai)受(shou)彈力(li)。在(zai)可能的地(di)方使用(yong)4個(ge)以上(shang)螺釘的等間距壓(ya)(ya)蓋(gai)，緊(jin)(jin)固(gu)(gu)壓(ya)(ya)蓋(gai)螺栓時(shi)，用(yong)塞(sai)尺檢查軸與壓(ya)(ya)蓋(gai)之間的間隙，這在(zai)密(mi)封(feng)(feng)腔(qiang)對(dui)壓(ya)(ya)蓋(gai)不(bu)導向時(shi)，顯得特(te)別重(zhong)要，因為壓(ya)(ya)蓋(gai)必須對(dui)中。
