羅平機械密封利用(yong)機械方式(shi)傳(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)力(li)和(he)運動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)的傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)，機械傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)在(zai)機械工(gong)程中應(ying)用(yong)非(fei)常廣(guang)泛，有(you)(you)多種形(xing)式(shi)，主要(yao)包括皮帶(dai)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、齒輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、鏈(lian)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、蝸(gua)桿蝸(gua)輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、齒輪齒條傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)和(he)螺旋傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)等(deng)。齒輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)能夠用(yong)于大功率的場(chang)(chang)合，傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)比(bi)(bi)準確，但一般要(yao)求較高(gao)的制造(zao)精度(du)和(he)安裝精度(du)。還(huan)有(you)(you)一類是靠機件間(jian)的摩擦(ca)力(li)傳(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)力(li)和(he)運動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)的摩擦(ca)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)，包括帶(dai)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)和(he)摩擦(ca)輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)等(deng)。摩擦(ca)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)容易實(shi)現無級變速，可以適應(ying)軸間(jian)距較大的傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)場(chang)(chang)合，而(er)過載打滑還(huan)能起到緩沖和(he)保護傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)裝置的作用(yong)，但這種傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)一般不能用(yong)于大功率的場(chang)(chang)合，也不能保證準確的傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)比(bi)(bi)。

　　傳動形式多，但是羅平機械密封的更換(huan)工(gong)作大同小異，首先拆(chai)前需確認(ren)電機處于檢修狀(zhuang)態，擰下加油螺塞，用吸(xi)管把密封座腔內的潤滑油吸(xi)出。準備好放(fang)置泵零件(jian)的工(gong)作臺(tai)及拆(chai)裝工(gong)具，切勿任意(yi)亂(luan)放(fang)亂(luan)用，避(bi)免碰壞泵的零部(bu)件(jian)。

　　拆(chai)對(dui)分式聯軸(zhou)器(qi)：先把聯軸(zhou)器(qi)的固定(ding)內六角螺釘擰(ning)下(xia)(xia)來，再輕(qing)輕(qing)把聯軸(zhou)器(qi)的一半(ban)從軸(zhou)上慢(man)慢(man)拉下(xia)(xia)，注意不要掉了(le)，再用(yong)梅花扳手擰(ning)下(xia)(xia)泵軸(zhou)吊緊(jin)螺栓(shuan)和擋塊，讓(rang)葉輪慢(man)慢(man)下(xia)(xia)沉至泵體，然后拆(chai)下(xia)(xia)另外一半(ban)聯軸(zhou)器(qi)，拿下(xia)(xia)泵軸(zhou)擋圈(quan)。

　　拆卸羅平機械密封：抓(zhua)住密封彈簧順著(zhu)泵軸往上提，就能拆下來了。

　　拆卸并清(qing)洗軸承(cheng)座(zuo)：先輕(qing)輕(qing)松動一下軸承(cheng)座(zuo)后用(yong)(yong)拆卸螺栓頂(ding)起軸承(cheng)座(zuo)，并且沿著泵軸往上提而卸下，再(zai)用(yong)(yong)噴氣(qi)燃料(liao)清(qing)洗軸承(cheng)及座(zuo)，裝前晾干并涂抹少許(xu)20號機械油用(yong)(yong)來潤滑保護。

　　拆密(mi)(mi)封(feng)座：擰(ning)下(xia)密(mi)(mi)封(feng)座壓緊(jin)螺母，輕輕卸下(xia)密(mi)(mi)封(feng)座并清(qing)洗。

　　羅平機械密封裝(zhuang)(zhuang)配：在(zai)(zai)動(dong)、靜環(huan)(huan)(huan)鏡面上(shang)涂一層潔凈的(de)20號潤滑油，導軸承座(zuo)也抹(mo)上(shang)潤滑油，先把靜環(huan)(huan)(huan)輕(qing)輕(qing)定(ding)位裝(zhuang)(zhuang)入(ru)導軸承座(zuo)，再在(zai)(zai)泵(beng)軸上(shang)抹(mo)上(shang)潤滑油，把動(dong)環(huan)(huan)(huan)部分輕(qing)輕(qing)裝(zhuang)(zhuang)入(ru)泵(beng)軸上(shang)，用手(shou)輕(qing)推密封環(huan)(huan)(huan)應能伸縮自如(ru)，注(zhu)意動(dong)、靜環(huan)(huan)(huan)部分的(de)防轉部位需(xu)裝(zhuang)(zhuang)配到位。

　　裝(zhuang)(zhuang)(zhuang)聯(lian)軸(zhou)器(qi)(qi)：在電機軸(zhou)頭(tou)上(shang)(shang)(shang)裝(zhuang)(zhuang)(zhuang)上(shang)(shang)(shang)擋圈(quan)，裝(zhuang)(zhuang)(zhuang)上(shang)(shang)(shang)一半聯(lian)軸(zhou)器(qi)(qi)，再在泵(beng)軸(zhou)端(duan)和聯(lian)軸(zhou)器(qi)(qi)槽內(nei)裝(zhuang)(zhuang)(zhuang)上(shang)(shang)(shang)擋塊并(bing)用梅花扳手擰緊螺(luo)栓(shuan)；再裝(zhuang)(zhuang)(zhuang)上(shang)(shang)(shang)另一半聯(lian)軸(zhou)器(qi)(qi)擰上(shang)(shang)(shang)內(nei)六角(jiao)螺(luo)釘。安(an)裝(zhuang)(zhuang)(zhuang)聯(lian)軸(zhou)器(qi)(qi)正(zheng)確(que)的檢查(cha)要求：對分式聯(lian)軸(zhou)器(qi)(qi)上(shang)(shang)(shang)下間隙(xi)需(xu)要均(jun)勻，用手盤動聯(lian)軸(zhou)器(qi)(qi)幾(ji)圈(quan)檢查(cha)轉動的靈活性(xing)。

　　裝(zhuang)密(mi)封座：先將密(mi)封座裝(zhuang)入橡膠油封，再(zai)把密(mi)封座裝(zhuang)入泵蓋(gai)(gai)(gai)并(bing)壓(ya)在軸(zhou)承座上，擰緊(jin)(jin)螺(luo)(luo)母(mu)，確保(bao)所有安裝(zhuang)螺(luo)(luo)釘(ding)緊(jin)(jin)固(gu)。當安裝(zhuang)螺(luo)(luo)釘(ding)被用作密(mi)封與(yu)軸(zhou)之間(jian)的(de)驅動時(shi)，軸(zhou)應打埋頭孔來加(jia)固(gu)連接，緊(jin)(jin)固(gu)壓(ya)蓋(gai)(gai)(gai)螺(luo)(luo)栓時(shi)應該平穩緊(jin)(jin)固(gu)，并(bing)且不要使(shi)(shi)壓(ya)蓋(gai)(gai)(gai)受彈(dan)力(li)。在可能的(de)地(di)方使(shi)(shi)用4個以上螺(luo)(luo)釘(ding)的(de)等間(jian)距壓(ya)蓋(gai)(gai)(gai)，緊(jin)(jin)固(gu)壓(ya)蓋(gai)(gai)(gai)螺(luo)(luo)栓時(shi)，用塞(sai)尺檢查軸(zhou)與(yu)壓(ya)蓋(gai)(gai)(gai)之間(jian)的(de)間(jian)隙，這在密(mi)封腔(qiang)對壓(ya)蓋(gai)(gai)(gai)不導向(xiang)時(shi)，顯得特別重要，因為壓(ya)蓋(gai)(gai)(gai)必須對中。
