羅平機械密封利用(yong)機械方式傳(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)(dong)力(li)(li)和(he)運動(dong)(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)，機械傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)在機械工程中應用(yong)非常廣泛(fan)，有多種形式，主要(yao)包括皮(pi)帶(dai)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、齒輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、蝸桿蝸輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、齒輪齒條傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)和(he)螺旋傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)等(deng)。齒輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)能(neng)夠用(yong)于(yu)大功率(lv)的(de)(de)(de)場(chang)合，傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比準確，但(dan)一(yi)般(ban)要(yao)求較(jiao)高的(de)(de)(de)制造(zao)精度(du)(du)和(he)安裝(zhuang)精度(du)(du)。還(huan)有一(yi)類(lei)是(shi)靠機件間的(de)(de)(de)摩擦(ca)力(li)(li)傳(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)(dong)力(li)(li)和(he)運動(dong)(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)摩擦(ca)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)，包括帶(dai)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)和(he)摩擦(ca)輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)等(deng)。摩擦(ca)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)容易實現無級變速，可以適應軸間距(ju)較(jiao)大的(de)(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)場(chang)合，而(er)過(guo)載打滑還(huan)能(neng)起到緩沖和(he)保護傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)裝(zhuang)置的(de)(de)(de)作(zuo)用(yong)，但(dan)這(zhe)種傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)一(yi)般(ban)不能(neng)用(yong)于(yu)大功率(lv)的(de)(de)(de)場(chang)合，也(ye)不能(neng)保證準確的(de)(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比。

　　傳動形式多，但是羅平機械密封的(de)更換工作(zuo)大同小(xiao)異(yi)，首先拆(chai)前(qian)需確認(ren)電機(ji)處于檢修狀態，擰下加油螺(luo)塞，用吸管(guan)把密封座腔(qiang)內的(de)潤滑(hua)油吸出。準備好放置(zhi)泵零(ling)件(jian)的(de)工作(zuo)臺及拆(chai)裝工具(ju)，切勿任意亂(luan)放亂(luan)用，避免(mian)碰(peng)壞泵的(de)零(ling)部件(jian)。

　　拆對分(fen)式聯(lian)軸器：先(xian)把聯(lian)軸器的固定(ding)內六角螺釘(ding)擰(ning)下(xia)(xia)來(lai)，再(zai)輕輕把聯(lian)軸器的一半從軸上慢慢拉下(xia)(xia)，注(zhu)意不要掉了，再(zai)用梅花扳手(shou)擰(ning)下(xia)(xia)泵軸吊緊螺栓(shuan)和擋塊(kuai)，讓葉(xie)輪慢慢下(xia)(xia)沉至泵體，然后拆下(xia)(xia)另外一半聯(lian)軸器，拿下(xia)(xia)泵軸擋圈。

　　拆卸羅平機械密封：抓住密封彈簧順(shun)著泵軸往上提，就能(neng)拆下來了。

　　拆卸(xie)(xie)并(bing)清(qing)洗(xi)(xi)軸承(cheng)座(zuo)：先輕輕松(song)動一(yi)下(xia)軸承(cheng)座(zuo)后用拆卸(xie)(xie)螺栓頂(ding)起(qi)軸承(cheng)座(zuo)，并(bing)且沿著泵軸往上提而卸(xie)(xie)下(xia)，再(zai)用噴氣燃料清(qing)洗(xi)(xi)軸承(cheng)及座(zuo)，裝前(qian)晾干并(bing)涂抹少(shao)許20號機械油用來潤滑保護。

　　拆密(mi)封(feng)座(zuo)(zuo)：擰下密(mi)封(feng)座(zuo)(zuo)壓緊(jin)螺母，輕輕卸(xie)下密(mi)封(feng)座(zuo)(zuo)并(bing)清(qing)洗。

　　羅平機械密封裝配(pei)：在動(dong)(dong)、靜(jing)(jing)環(huan)鏡面上涂一(yi)層潔(jie)凈的20號潤滑油，導軸(zhou)承(cheng)座也抹上潤滑油，先(xian)把靜(jing)(jing)環(huan)輕(qing)輕(qing)定位(wei)裝入導軸(zhou)承(cheng)座，再在泵軸(zhou)上抹上潤滑油，把動(dong)(dong)環(huan)部分輕(qing)輕(qing)裝入泵軸(zhou)上，用手輕(qing)推密封(feng)環(huan)應能伸縮自(zi)如(ru)，注意動(dong)(dong)、靜(jing)(jing)環(huan)部分的防轉(zhuan)部位(wei)需(xu)裝配(pei)到位(wei)。

　　裝(zhuang)(zhuang)(zhuang)(zhuang)聯(lian)軸(zhou)(zhou)(zhou)器(qi)：在電機(ji)軸(zhou)(zhou)(zhou)頭上(shang)(shang)(shang)(shang)裝(zhuang)(zhuang)(zhuang)(zhuang)上(shang)(shang)(shang)(shang)擋(dang)圈，裝(zhuang)(zhuang)(zhuang)(zhuang)上(shang)(shang)(shang)(shang)一半(ban)聯(lian)軸(zhou)(zhou)(zhou)器(qi)，再在泵軸(zhou)(zhou)(zhou)端和聯(lian)軸(zhou)(zhou)(zhou)器(qi)槽內裝(zhuang)(zhuang)(zhuang)(zhuang)上(shang)(shang)(shang)(shang)擋(dang)塊并用梅(mei)花扳(ban)手擰(ning)緊螺栓；再裝(zhuang)(zhuang)(zhuang)(zhuang)上(shang)(shang)(shang)(shang)另一半(ban)聯(lian)軸(zhou)(zhou)(zhou)器(qi)擰(ning)上(shang)(shang)(shang)(shang)內六角螺釘。安裝(zhuang)(zhuang)(zhuang)(zhuang)聯(lian)軸(zhou)(zhou)(zhou)器(qi)正確(que)的檢查(cha)要求(qiu)：對分式聯(lian)軸(zhou)(zhou)(zhou)器(qi)上(shang)(shang)(shang)(shang)下間隙(xi)需要均勻(yun)，用手盤動(dong)聯(lian)軸(zhou)(zhou)(zhou)器(qi)幾圈檢查(cha)轉動(dong)的靈活性。

　　裝(zhuang)密(mi)封座(zuo)：先將(jiang)密(mi)封座(zuo)裝(zhuang)入(ru)橡膠油封，再把密(mi)封座(zuo)裝(zhuang)入(ru)泵(beng)蓋并壓(ya)在軸(zhou)承座(zuo)上(shang)，擰緊螺(luo)(luo)母(mu)，確保所有(you)安(an)裝(zhuang)螺(luo)(luo)釘(ding)緊固(gu)。當安(an)裝(zhuang)螺(luo)(luo)釘(ding)被(bei)用(yong)(yong)作密(mi)封與軸(zhou)之間(jian)的驅動時(shi)(shi)，軸(zhou)應打埋頭孔來加固(gu)連(lian)接(jie)，緊固(gu)壓(ya)蓋螺(luo)(luo)栓時(shi)(shi)應該平穩緊固(gu)，并且(qie)不(bu)要(yao)使壓(ya)蓋受彈(dan)力(li)。在可能的地方使用(yong)(yong)4個以上(shang)螺(luo)(luo)釘(ding)的等間(jian)距壓(ya)蓋，緊固(gu)壓(ya)蓋螺(luo)(luo)栓時(shi)(shi)，用(yong)(yong)塞尺檢查軸(zhou)與壓(ya)蓋之間(jian)的間(jian)隙，這在密(mi)封腔對壓(ya)蓋不(bu)導(dao)向時(shi)(shi)，顯得特別重要(yao)，因為壓(ya)蓋必須對中。
