洪梅鎮機械密封利用(yong)機械(xie)方(fang)式(shi)傳(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)力和(he)運動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)的傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)，機械(xie)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)在機械(xie)工程(cheng)中應用(yong)非常廣泛，有(you)多(duo)種形式(shi)，主要包括皮帶傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、齒輪傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、鏈(lian)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、蝸桿蝸輪傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、齒輪齒條傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)和(he)螺旋(xuan)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)等。齒輪傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)能夠用(yong)于大(da)功率(lv)的場合，傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)比準(zhun)確(que)，但一(yi)般(ban)要求較(jiao)高的制造精(jing)度和(he)安(an)裝精(jing)度。還有(you)一(yi)類是(shi)靠(kao)機件(jian)間的摩擦(ca)力傳(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)力和(he)運動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)的摩擦(ca)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)，包括帶傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)和(he)摩擦(ca)輪傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)等。摩擦(ca)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)容易實現(xian)無(wu)級變(bian)速，可以適(shi)應軸間距較(jiao)大(da)的傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)場合，而過載打滑還能起到緩(huan)沖(chong)和(he)保護傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)裝置(zhi)的作用(yong)，但這(zhe)種傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)一(yi)般(ban)不能用(yong)于大(da)功率(lv)的場合，也不能保證(zheng)準(zhun)確(que)的傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)比。

　　傳動形式多，但是洪梅鎮機械密封的(de)更換工作(zuo)大同小異，首先拆(chai)前需確認(ren)電機處于檢修狀(zhuang)態，擰(ning)下加油(you)螺塞，用(yong)吸管把密封座腔內的(de)潤(run)滑油(you)吸出。準備好放(fang)置(zhi)泵零件(jian)的(de)工作(zuo)臺(tai)及(ji)拆(chai)裝工具，切勿任意亂放(fang)亂用(yong)，避(bi)免碰壞泵的(de)零部件(jian)。

　　拆(chai)對分式聯軸(zhou)(zhou)器：先把聯軸(zhou)(zhou)器的固定內六角螺釘(ding)擰下(xia)(xia)來，再(zai)輕輕把聯軸(zhou)(zhou)器的一半(ban)從(cong)軸(zhou)(zhou)上慢(man)慢(man)拉下(xia)(xia)，注(zhu)意不要掉了，再(zai)用梅花扳(ban)手擰下(xia)(xia)泵(beng)軸(zhou)(zhou)吊緊(jin)螺栓和(he)擋塊，讓(rang)葉輪慢(man)慢(man)下(xia)(xia)沉至泵(beng)體(ti)，然后拆(chai)下(xia)(xia)另外一半(ban)聯軸(zhou)(zhou)器，拿下(xia)(xia)泵(beng)軸(zhou)(zhou)擋圈。

　　拆卸洪梅鎮機械密封：抓住密封彈簧順著泵(beng)軸往(wang)上提，就能拆下來了。

　　拆(chai)(chai)卸(xie)并清洗軸承座：先輕輕松動一下軸承座后用拆(chai)(chai)卸(xie)螺栓頂起軸承座，并且沿(yan)著(zhu)泵軸往(wang)上提(ti)而卸(xie)下，再用噴氣燃料清洗軸承及座，裝前晾干并涂抹(mo)少許20號機械油用來潤滑保(bao)護。

　　拆密(mi)封(feng)(feng)座：擰下密(mi)封(feng)(feng)座壓緊螺母，輕(qing)輕(qing)卸下密(mi)封(feng)(feng)座并清洗。

　　洪梅鎮機械密封裝(zhuang)配：在(zai)動、靜(jing)環(huan)(huan)(huan)鏡面上(shang)涂一層潔凈(jing)的20號潤(run)滑油，導軸承座也(ye)抹上(shang)潤(run)滑油，先把靜(jing)環(huan)(huan)(huan)輕(qing)輕(qing)定位(wei)(wei)裝(zhuang)入(ru)導軸承座，再在(zai)泵軸上(shang)抹上(shang)潤(run)滑油，把動環(huan)(huan)(huan)部分(fen)輕(qing)輕(qing)裝(zhuang)入(ru)泵軸上(shang)，用手輕(qing)推密封環(huan)(huan)(huan)應能伸縮自如，注意動、靜(jing)環(huan)(huan)(huan)部分(fen)的防轉部位(wei)(wei)需(xu)裝(zhuang)配到位(wei)(wei)。

　　裝聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)：在電(dian)機軸(zhou)(zhou)(zhou)(zhou)頭上(shang)裝上(shang)擋圈，裝上(shang)一(yi)半(ban)聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)，再在泵軸(zhou)(zhou)(zhou)(zhou)端和聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)槽內裝上(shang)擋塊并用梅花扳手擰(ning)緊螺栓；再裝上(shang)另一(yi)半(ban)聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)擰(ning)上(shang)內六角(jiao)螺釘。安裝聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)正確的檢(jian)查(cha)要求：對分(fen)式(shi)聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)上(shang)下間隙需(xu)要均(jun)勻，用手盤動(dong)(dong)聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)幾圈檢(jian)查(cha)轉動(dong)(dong)的靈活性。

　　裝密(mi)封座(zuo)(zuo)：先(xian)將密(mi)封座(zuo)(zuo)裝入(ru)橡膠油(you)封，再把密(mi)封座(zuo)(zuo)裝入(ru)泵蓋(gai)并(bing)壓(ya)(ya)(ya)在(zai)軸(zhou)承座(zuo)(zuo)上(shang)，擰緊螺(luo)母(mu)，確保所(suo)有安裝螺(luo)釘緊固(gu)(gu)。當安裝螺(luo)釘被用作密(mi)封與(yu)軸(zhou)之間(jian)(jian)的(de)驅(qu)動時，軸(zhou)應打埋頭孔來(lai)加固(gu)(gu)連接，緊固(gu)(gu)壓(ya)(ya)(ya)蓋(gai)螺(luo)栓(shuan)時應該平穩緊固(gu)(gu)，并(bing)且不要使(shi)壓(ya)(ya)(ya)蓋(gai)受彈力(li)。在(zai)可能的(de)地方使(shi)用4個以(yi)上(shang)螺(luo)釘的(de)等間(jian)(jian)距壓(ya)(ya)(ya)蓋(gai)，緊固(gu)(gu)壓(ya)(ya)(ya)蓋(gai)螺(luo)栓(shuan)時，用塞尺檢(jian)查軸(zhou)與(yu)壓(ya)(ya)(ya)蓋(gai)之間(jian)(jian)的(de)間(jian)(jian)隙，這在(zai)密(mi)封腔對(dui)壓(ya)(ya)(ya)蓋(gai)不導向時，顯(xian)得特別(bie)重要，因為壓(ya)(ya)(ya)蓋(gai)必須對(dui)中(zhong)。
