梅江機械密封利用機(ji)(ji)械方式傳(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)力(li)和運動(dong)(dong)(dong)(dong)(dong)的傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，機(ji)(ji)械傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)在機(ji)(ji)械工程(cheng)中應用非常(chang)廣泛，有多種形式，主要包括皮帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒輪(lun)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(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒輪(lun)齒條傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和螺旋傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等(deng)(deng)。齒輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)能(neng)夠(gou)用于大(da)功(gong)率(lv)的場(chang)合，傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比(bi)(bi)準確，但(dan)一(yi)般要求較高的制造精度和安裝(zhuang)精度。還有一(yi)類(lei)是靠機(ji)(ji)件間的摩擦(ca)力(li)傳(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)力(li)和運動(dong)(dong)(dong)(dong)(dong)的摩擦(ca)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，包括帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和摩擦(ca)輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等(deng)(deng)。摩擦(ca)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)容易(yi)實(shi)現(xian)無(wu)級變速，可以適應軸間距較大(da)的傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)場(chang)合，而(er)過載打滑還能(neng)起到緩沖和保護傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)裝(zhuang)置(zhi)的作用，但(dan)這種傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)一(yi)般不(bu)(bu)能(neng)用于大(da)功(gong)率(lv)的場(chang)合，也不(bu)(bu)能(neng)保證準確的傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比(bi)(bi)。

　　傳動形式多，但是梅江機械密封的更換工(gong)作大同小異，首(shou)先拆前需確認電機處(chu)于檢修狀態，擰下(xia)加油螺塞，用吸(xi)管把密(mi)封座腔內(nei)的潤滑油吸(xi)出。準備(bei)好放(fang)置(zhi)泵(beng)(beng)零件(jian)的工(gong)作臺及拆裝工(gong)具，切勿任(ren)意亂放(fang)亂用，避(bi)免碰壞泵(beng)(beng)的零部件(jian)。

　　拆對(dui)分式聯(lian)軸(zhou)(zhou)器(qi)：先把聯(lian)軸(zhou)(zhou)器(qi)的固(gu)定內六角螺釘擰下(xia)來，再(zai)輕輕把聯(lian)軸(zhou)(zhou)器(qi)的一(yi)半從軸(zhou)(zhou)上慢(man)慢(man)拉(la)下(xia)，注意不要掉(diao)了，再(zai)用梅花(hua)扳手擰下(xia)泵(beng)軸(zhou)(zhou)吊緊(jin)螺栓和擋(dang)塊，讓(rang)葉輪(lun)慢(man)慢(man)下(xia)沉至泵(beng)體(ti)，然后拆下(xia)另外一(yi)半聯(lian)軸(zhou)(zhou)器(qi)，拿(na)下(xia)泵(beng)軸(zhou)(zhou)擋(dang)圈。

　　拆卸梅江機械密封：抓住密封彈(dan)簧順(shun)著泵軸(zhou)往上提，就能拆(chai)下(xia)來了。

　　拆卸(xie)并(bing)清洗軸(zhou)(zhou)承(cheng)座(zuo)：先輕輕松動一(yi)下軸(zhou)(zhou)承(cheng)座(zuo)后用(yong)拆卸(xie)螺栓頂起軸(zhou)(zhou)承(cheng)座(zuo)，并(bing)且沿著泵軸(zhou)(zhou)往上提而卸(xie)下，再用(yong)噴(pen)氣(qi)燃料清洗軸(zhou)(zhou)承(cheng)及座(zuo)，裝(zhuang)前晾干并(bing)涂抹少許20號(hao)機械(xie)油用(yong)來潤滑保護。

　　拆密封(feng)座(zuo)：擰下密封(feng)座(zuo)壓(ya)緊螺母，輕輕卸(xie)下密封(feng)座(zuo)并清洗。

　　梅江機械密封裝(zhuang)(zhuang)配：在動(dong)、靜環(huan)鏡(jing)面(mian)上涂一層潔凈的20號潤(run)(run)滑油(you)，導軸承(cheng)(cheng)座也抹上潤(run)(run)滑油(you)，先把靜環(huan)輕(qing)輕(qing)定(ding)位裝(zhuang)(zhuang)入導軸承(cheng)(cheng)座，再在泵(beng)軸上抹上潤(run)(run)滑油(you)，把動(dong)環(huan)部(bu)(bu)分輕(qing)輕(qing)裝(zhuang)(zhuang)入泵(beng)軸上，用手輕(qing)推密封環(huan)應能伸縮自如，注意動(dong)、靜環(huan)部(bu)(bu)分的防轉部(bu)(bu)位需裝(zhuang)(zhuang)配到(dao)位。

　　裝聯(lian)(lian)軸器(qi)：在電(dian)機軸頭上(shang)裝上(shang)擋圈(quan)，裝上(shang)一(yi)半聯(lian)(lian)軸器(qi)，再(zai)在泵軸端和聯(lian)(lian)軸器(qi)槽(cao)內裝上(shang)擋塊(kuai)并用梅花扳手(shou)(shou)擰(ning)緊螺栓(shuan)；再(zai)裝上(shang)另一(yi)半聯(lian)(lian)軸器(qi)擰(ning)上(shang)內六角(jiao)螺釘。安裝聯(lian)(lian)軸器(qi)正確的(de)檢查要(yao)求：對分式聯(lian)(lian)軸器(qi)上(shang)下間隙需要(yao)均勻，用手(shou)(shou)盤動(dong)聯(lian)(lian)軸器(qi)幾圈(quan)檢查轉動(dong)的(de)靈活性。

　　裝(zhuang)密封(feng)座(zuo)：先將密封(feng)座(zuo)裝(zhuang)入橡(xiang)膠油封(feng)，再把密封(feng)座(zuo)裝(zhuang)入泵蓋(gai)(gai)并壓(ya)在軸(zhou)承(cheng)座(zuo)上，擰緊螺母，確保所有安(an)裝(zhuang)螺釘(ding)緊固(gu)。當安(an)裝(zhuang)螺釘(ding)被(bei)用(yong)作密封(feng)與軸(zhou)之(zhi)間(jian)的驅(qu)動(dong)時(shi)，軸(zhou)應(ying)打埋頭孔(kong)來(lai)加固(gu)連接，緊固(gu)壓(ya)蓋(gai)(gai)螺栓(shuan)時(shi)應(ying)該平穩緊固(gu)，并且不(bu)要(yao)使(shi)壓(ya)蓋(gai)(gai)受(shou)彈力(li)。在可能的地方使(shi)用(yong)4個以上螺釘(ding)的等間(jian)距壓(ya)蓋(gai)(gai)，緊固(gu)壓(ya)蓋(gai)(gai)螺栓(shuan)時(shi)，用(yong)塞尺檢查(cha)軸(zhou)與壓(ya)蓋(gai)(gai)之(zhi)間(jian)的間(jian)隙，這在密封(feng)腔對壓(ya)蓋(gai)(gai)不(bu)導(dao)向時(shi)，顯(xian)得特別重要(yao)，因為壓(ya)蓋(gai)(gai)必須對中。
