洪山機械密封利用(yong)機械方式(shi)傳(chuan)(chuan)遞動(dong)(dong)(dong)力和(he)運(yun)動(dong)(dong)(dong)的(de)傳(chuan)(chuan)動(dong)(dong)(dong),機械傳(chuan)(chuan)動(dong)(dong)(dong)在機械工程中(zhong)應(ying)用(yong)非(fei)常(chang)廣(guang)泛,有多種形(xing)式(shi),主要包括(kuo)皮帶(dai)傳(chuan)(chuan)動(dong)(dong)(dong)、齒(chi)(chi)輪(lun)(lun)(lun)傳(chuan)(chuan)動(dong)(dong)(dong)、鏈傳(chuan)(chuan)動(dong)(dong)(dong)、蝸桿蝸輪(lun)(lun)(lun)傳(chuan)(chuan)動(dong)(dong)(dong)、齒(chi)(chi)輪(lun)(lun)(lun)齒(chi)(chi)條傳(chuan)(chuan)動(dong)(dong)(dong)和(he)螺(luo)旋傳(chuan)(chuan)動(dong)(dong)(dong)等(deng)。齒(chi)(chi)輪(lun)(lun)(lun)傳(chuan)(chuan)動(dong)(dong)(dong)能夠用(yong)于大(da)(da)功(gong)率(lv)的(de)場(chang)合(he)(he),傳(chuan)(chuan)動(dong)(dong)(dong)比(bi)準(zhun)確(que),但一(yi)般(ban)(ban)要求較(jiao)高(gao)的(de)制造精度和(he)安裝精度。還(huan)有一(yi)類是(shi)靠(kao)機件間的(de)摩(mo)(mo)擦(ca)(ca)力傳(chuan)(chuan)遞動(dong)(dong)(dong)力和(he)運(yun)動(dong)(dong)(dong)的(de)摩(mo)(mo)擦(ca)(ca)傳(chuan)(chuan)動(dong)(dong)(dong),包括(kuo)帶(dai)傳(chuan)(chuan)動(dong)(dong)(dong)、繩傳(chuan)(chuan)動(dong)(dong)(dong)和(he)摩(mo)(mo)擦(ca)(ca)輪(lun)(lun)(lun)傳(chuan)(chuan)動(dong)(dong)(dong)等(deng)。摩(mo)(mo)擦(ca)(ca)傳(chuan)(chuan)動(dong)(dong)(dong)容易實現無(wu)級變速,可以適(shi)應(ying)軸間距較(jiao)大(da)(da)的(de)傳(chuan)(chuan)動(dong)(dong)(dong)場(chang)合(he)(he),而(er)過載打滑還(huan)能起到緩沖和(he)保護傳(chuan)(chuan)動(dong)(dong)(dong)裝置的(de)作用(yong),但這種傳(chuan)(chuan)動(dong)(dong)(dong)一(yi)般(ban)(ban)不(bu)能用(yong)于大(da)(da)功(gong)率(lv)的(de)場(chang)合(he)(he),也不(bu)能保證準(zhun)確(que)的(de)傳(chuan)(chuan)動(dong)(dong)(dong)比(bi)。
傳動形式多,但是洪山機械密封的更換(huan)工作大同(tong)小異,首先拆前需確(que)認(ren)電機處于檢(jian)修狀態,擰下加油螺(luo)塞,用吸管把密封座腔內的潤(run)滑油吸出。準備好放置泵(beng)零(ling)件(jian)的工作臺(tai)及拆裝工具,切勿任意亂放亂用,避(bi)免碰(peng)壞泵(beng)的零(ling)部(bu)件(jian)。
拆對(dui)分式聯軸(zhou)(zhou)器(qi):先把(ba)(ba)聯軸(zhou)(zhou)器(qi)的(de)固定內六角螺釘(ding)擰(ning)下(xia)來,再(zai)輕(qing)輕(qing)把(ba)(ba)聯軸(zhou)(zhou)器(qi)的(de)一半(ban)從(cong)軸(zhou)(zhou)上慢(man)慢(man)拉(la)下(xia),注意不要掉了,再(zai)用梅花扳手擰(ning)下(xia)泵軸(zhou)(zhou)吊緊螺栓和(he)擋塊,讓葉(xie)輪慢(man)慢(man)下(xia)沉至(zhi)泵體,然(ran)后拆下(xia)另外一半(ban)聯軸(zhou)(zhou)器(qi),拿下(xia)泵軸(zhou)(zhou)擋圈。
拆卸洪山機械密封:抓住(zhu)密封彈(dan)簧順著泵軸往上(shang)提,就能拆下(xia)來了(le)。
拆卸并(bing)清洗軸(zhou)承(cheng)座(zuo):先(xian)輕(qing)輕(qing)松動一下(xia)軸(zhou)承(cheng)座(zuo)后用(yong)(yong)拆卸螺(luo)栓頂起軸(zhou)承(cheng)座(zuo),并(bing)且(qie)沿(yan)著泵軸(zhou)往上提而卸下(xia),再(zai)用(yong)(yong)噴氣(qi)燃(ran)料清洗軸(zhou)承(cheng)及座(zuo),裝(zhuang)前晾干并(bing)涂(tu)抹少許20號機械油用(yong)(yong)來潤(run)滑保護。
拆密封座:擰下(xia)密封座壓(ya)緊螺母,輕輕卸下(xia)密封座并清(qing)洗。
洪山機械密封裝(zhuang)(zhuang)配:在(zai)動、靜(jing)環(huan)鏡面上(shang)涂一層潔凈的20號潤滑油,導軸(zhou)承(cheng)座(zuo)也抹上(shang)潤滑油,先把靜(jing)環(huan)輕(qing)(qing)輕(qing)(qing)定位裝(zhuang)(zhuang)入導軸(zhou)承(cheng)座(zuo),再在(zai)泵軸(zhou)上(shang)抹上(shang)潤滑油,把動環(huan)部(bu)分輕(qing)(qing)輕(qing)(qing)裝(zhuang)(zhuang)入泵軸(zhou)上(shang),用手輕(qing)(qing)推(tui)密(mi)封環(huan)應能伸(shen)縮(suo)自如,注意動、靜(jing)環(huan)部(bu)分的防(fang)轉部(bu)位需裝(zhuang)(zhuang)配到位。
裝聯(lian)(lian)軸(zhou)器(qi):在(zai)電機軸(zhou)頭上(shang)(shang)裝上(shang)(shang)擋(dang)圈,裝上(shang)(shang)一半(ban)聯(lian)(lian)軸(zhou)器(qi),再(zai)在(zai)泵(beng)軸(zhou)端和聯(lian)(lian)軸(zhou)器(qi)槽內(nei)裝上(shang)(shang)擋(dang)塊并用梅花扳手擰(ning)緊(jin)螺栓;再(zai)裝上(shang)(shang)另(ling)一半(ban)聯(lian)(lian)軸(zhou)器(qi)擰(ning)上(shang)(shang)內(nei)六角(jiao)螺釘。安裝聯(lian)(lian)軸(zhou)器(qi)正確的(de)檢查(cha)要求(qiu):對分式(shi)聯(lian)(lian)軸(zhou)器(qi)上(shang)(shang)下間隙需(xu)要均勻,用手盤動聯(lian)(lian)軸(zhou)器(qi)幾圈檢查(cha)轉(zhuan)動的(de)靈活(huo)性。
裝密(mi)封(feng)座(zuo):先將密(mi)封(feng)座(zuo)裝入橡膠油(you)封(feng),再把密(mi)封(feng)座(zuo)裝入泵蓋(gai)(gai)并(bing)壓(ya)(ya)在軸承座(zuo)上(shang)(shang),擰(ning)緊螺(luo)母,確保所有安裝螺(luo)釘(ding)(ding)緊固(gu)。當安裝螺(luo)釘(ding)(ding)被用作密(mi)封(feng)與軸之(zhi)間(jian)的(de)驅(qu)動(dong)時,軸應(ying)打埋頭孔(kong)來加固(gu)連接,緊固(gu)壓(ya)(ya)蓋(gai)(gai)螺(luo)栓(shuan)時應(ying)該平穩緊固(gu),并(bing)且不(bu)要(yao)使壓(ya)(ya)蓋(gai)(gai)受(shou)彈(dan)力。在可能的(de)地(di)方使用4個以上(shang)(shang)螺(luo)釘(ding)(ding)的(de)等間(jian)距壓(ya)(ya)蓋(gai)(gai),緊固(gu)壓(ya)(ya)蓋(gai)(gai)螺(luo)栓(shuan)時,用塞尺檢查軸與壓(ya)(ya)蓋(gai)(gai)之(zhi)間(jian)的(de)間(jian)隙,這在密(mi)封(feng)腔對壓(ya)(ya)蓋(gai)(gai)不(bu)導向(xiang)時,顯(xian)得(de)特(te)別(bie)重要(yao),因為壓(ya)(ya)蓋(gai)(gai)必(bi)須對中。
