萊陽機械密封利用(yong)機(ji)械(xie)(xie)方式傳(chuan)(chuan)(chuan)遞動(dong)(dong)力和(he)運(yun)動(dong)(dong)的(de)傳(chuan)(chuan)(chuan)動(dong)(dong),機(ji)械(xie)(xie)傳(chuan)(chuan)(chuan)動(dong)(dong)在(zai)機(ji)械(xie)(xie)工程中應用(yong)非常廣泛(fan),有多種形式,主要包(bao)括皮帶傳(chuan)(chuan)(chuan)動(dong)(dong)、齒(chi)輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)、鏈傳(chuan)(chuan)(chuan)動(dong)(dong)、蝸(gua)桿蝸(gua)輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)、齒(chi)輪(lun)齒(chi)條傳(chuan)(chuan)(chuan)動(dong)(dong)和(he)螺旋(xuan)傳(chuan)(chuan)(chuan)動(dong)(dong)等。齒(chi)輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)能夠用(yong)于大(da)功率(lv)的(de)場合,傳(chuan)(chuan)(chuan)動(dong)(dong)比準確,但一般要求較高的(de)制(zhi)造(zao)精(jing)度(du)和(he)安(an)裝(zhuang)精(jing)度(du)。還有一類(lei)是靠機(ji)件間(jian)(jian)的(de)摩擦(ca)力傳(chuan)(chuan)(chuan)遞動(dong)(dong)力和(he)運(yun)動(dong)(dong)的(de)摩擦(ca)傳(chuan)(chuan)(chuan)動(dong)(dong),包(bao)括帶傳(chuan)(chuan)(chuan)動(dong)(dong)、繩傳(chuan)(chuan)(chuan)動(dong)(dong)和(he)摩擦(ca)輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)等。摩擦(ca)傳(chuan)(chuan)(chuan)動(dong)(dong)容(rong)易實現無級變速(su),可以(yi)適應軸間(jian)(jian)距較大(da)的(de)傳(chuan)(chuan)(chuan)動(dong)(dong)場合,而過載打滑還能起到緩沖和(he)保護傳(chuan)(chuan)(chuan)動(dong)(dong)裝(zhuang)置的(de)作(zuo)用(yong),但這種傳(chuan)(chuan)(chuan)動(dong)(dong)一般不(bu)能用(yong)于大(da)功率(lv)的(de)場合,也不(bu)能保證準確的(de)傳(chuan)(chuan)(chuan)動(dong)(dong)比。
傳動形式多,但是萊陽機械密封的(de)(de)更換(huan)工(gong)作大同(tong)小異,首(shou)先拆(chai)前需確(que)認(ren)電(dian)機處(chu)于檢修(xiu)狀態,擰下加油螺塞,用(yong)吸(xi)管把密封座(zuo)腔(qiang)內(nei)的(de)(de)潤(run)滑(hua)油吸(xi)出。準備好放置泵(beng)零件的(de)(de)工(gong)作臺(tai)及拆(chai)裝(zhuang)工(gong)具,切勿任意亂放亂用(yong),避免碰(peng)壞泵(beng)的(de)(de)零部件。
拆對分(fen)式聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi):先把聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)的固定(ding)內六角螺釘擰(ning)下(xia)(xia)(xia)來,再(zai)輕輕把聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)的一半從軸(zhou)(zhou)(zhou)上慢慢拉下(xia)(xia)(xia),注意不要(yao)掉了,再(zai)用梅花扳手擰(ning)下(xia)(xia)(xia)泵軸(zhou)(zhou)(zhou)吊緊螺栓和擋塊,讓(rang)葉輪慢慢下(xia)(xia)(xia)沉至泵體,然后拆下(xia)(xia)(xia)另(ling)外(wai)一半聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi),拿(na)下(xia)(xia)(xia)泵軸(zhou)(zhou)(zhou)擋圈。
拆卸萊陽機械密封:抓住密(mi)封彈(dan)簧順(shun)著(zhu)泵軸往上(shang)提,就能拆(chai)下來了(le)。
拆(chai)卸(xie)并清洗軸承座:先輕(qing)輕(qing)松(song)動一下軸承座后(hou)用拆(chai)卸(xie)螺栓頂起軸承座,并且沿著泵(beng)軸往上提而卸(xie)下,再用噴氣(qi)燃料清洗軸承及座,裝前晾(liang)干并涂抹(mo)少許20號機械油用來(lai)潤滑保(bao)護。
拆密(mi)封(feng)(feng)座(zuo):擰下密(mi)封(feng)(feng)座(zuo)壓緊螺母,輕(qing)輕(qing)卸下密(mi)封(feng)(feng)座(zuo)并清(qing)洗(xi)。
萊陽機械密封裝配:在動、靜環(huan)鏡面上涂(tu)一層(ceng)潔凈(jing)的20號潤(run)滑油,導軸(zhou)承(cheng)座也抹上潤(run)滑油,先把靜環(huan)輕(qing)輕(qing)定位裝入(ru)(ru)導軸(zhou)承(cheng)座,再在泵軸(zhou)上抹上潤(run)滑油,把動環(huan)部分輕(qing)輕(qing)裝入(ru)(ru)泵軸(zhou)上,用手輕(qing)推密封(feng)環(huan)應(ying)能伸縮(suo)自如,注意動、靜環(huan)部分的防轉部位需裝配到位。
裝聯(lian)(lian)軸器(qi):在電(dian)機(ji)軸頭(tou)上(shang)裝上(shang)擋(dang)圈,裝上(shang)一半(ban)聯(lian)(lian)軸器(qi),再在泵軸端和聯(lian)(lian)軸器(qi)槽內裝上(shang)擋(dang)塊并用梅花扳手(shou)擰緊螺栓;再裝上(shang)另一半(ban)聯(lian)(lian)軸器(qi)擰上(shang)內六角螺釘。安裝聯(lian)(lian)軸器(qi)正(zheng)確(que)的(de)檢查要求:對分式聯(lian)(lian)軸器(qi)上(shang)下(xia)間(jian)隙需要均勻,用手(shou)盤(pan)動(dong)聯(lian)(lian)軸器(qi)幾圈檢查轉動(dong)的(de)靈(ling)活性(xing)。
裝(zhuang)密(mi)封座(zuo)(zuo):先(xian)將密(mi)封座(zuo)(zuo)裝(zhuang)入(ru)橡(xiang)膠油封,再把密(mi)封座(zuo)(zuo)裝(zhuang)入(ru)泵蓋(gai)(gai)并壓(ya)在軸(zhou)承座(zuo)(zuo)上(shang),擰緊螺(luo)(luo)母(mu),確保所有安(an)裝(zhuang)螺(luo)(luo)釘緊固(gu)。當安(an)裝(zhuang)螺(luo)(luo)釘被用(yong)(yong)作密(mi)封與軸(zhou)之間(jian)的驅(qu)動(dong)時,軸(zhou)應打埋頭孔來加(jia)固(gu)連接,緊固(gu)壓(ya)蓋(gai)(gai)螺(luo)(luo)栓時應該平穩(wen)緊固(gu),并且不要(yao)使壓(ya)蓋(gai)(gai)受彈力(li)。在可能(neng)的地方使用(yong)(yong)4個(ge)以上(shang)螺(luo)(luo)釘的等間(jian)距壓(ya)蓋(gai)(gai),緊固(gu)壓(ya)蓋(gai)(gai)螺(luo)(luo)栓時,用(yong)(yong)塞尺檢(jian)查(cha)軸(zhou)與壓(ya)蓋(gai)(gai)之間(jian)的間(jian)隙,這在密(mi)封腔對壓(ya)蓋(gai)(gai)不導向時,顯得特別重(zhong)要(yao),因為壓(ya)蓋(gai)(gai)必(bi)須對中。
