湟中機械密封利用機械方式(shi)傳(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)力和(he)(he)(he)運(yun)動(dong)(dong)(dong)(dong)(dong)的(de)傳(chuan)動(dong)(dong)(dong)(dong)(dong),機械傳(chuan)動(dong)(dong)(dong)(dong)(dong)在機械工程中應用非常廣泛,有多種(zhong)形式(shi),主要(yao)包(bao)括皮(pi)帶傳(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)(chi)輪(lun)(lun)傳(chuan)動(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)動(dong)(dong)(dong)(dong)(dong)、蝸桿蝸輪(lun)(lun)傳(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)(chi)輪(lun)(lun)齒(chi)(chi)條傳(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)(he)(he)螺旋傳(chuan)動(dong)(dong)(dong)(dong)(dong)等。齒(chi)(chi)輪(lun)(lun)傳(chuan)動(dong)(dong)(dong)(dong)(dong)能(neng)(neng)夠用于大功率(lv)的(de)場(chang)(chang)合(he)(he),傳(chuan)動(dong)(dong)(dong)(dong)(dong)比準確(que),但一(yi)般要(yao)求較高的(de)制造精度和(he)(he)(he)安裝(zhuang)精度。還(huan)有一(yi)類是靠機件間的(de)摩擦(ca)力傳(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)力和(he)(he)(he)運(yun)動(dong)(dong)(dong)(dong)(dong)的(de)摩擦(ca)傳(chuan)動(dong)(dong)(dong)(dong)(dong),包(bao)括帶傳(chuan)動(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)(he)(he)摩擦(ca)輪(lun)(lun)傳(chuan)動(dong)(dong)(dong)(dong)(dong)等。摩擦(ca)傳(chuan)動(dong)(dong)(dong)(dong)(dong)容易(yi)實現無(wu)級變(bian)速,可以適應軸間距(ju)較大的(de)傳(chuan)動(dong)(dong)(dong)(dong)(dong)場(chang)(chang)合(he)(he),而(er)過載打滑還(huan)能(neng)(neng)起到(dao)緩沖和(he)(he)(he)保護傳(chuan)動(dong)(dong)(dong)(dong)(dong)裝(zhuang)置(zhi)的(de)作用,但這種(zhong)傳(chuan)動(dong)(dong)(dong)(dong)(dong)一(yi)般不能(neng)(neng)用于大功率(lv)的(de)場(chang)(chang)合(he)(he),也(ye)不能(neng)(neng)保證(zheng)準確(que)的(de)傳(chuan)動(dong)(dong)(dong)(dong)(dong)比。
傳動形式多,但是湟中機械密封的更換工作(zuo)大同小異,首先(xian)拆前需確(que)認(ren)電機(ji)處于檢修狀態,擰下加油(you)螺塞,用(yong)吸管(guan)把密封座腔內的潤滑油(you)吸出(chu)。準(zhun)備好放(fang)置泵零件(jian)的工作(zuo)臺及拆裝工具,切勿(wu)任意亂(luan)放(fang)亂(luan)用(yong),避免碰壞泵的零部件(jian)。
拆(chai)對分式聯軸器(qi)(qi):先把聯軸器(qi)(qi)的固定內六角螺(luo)(luo)釘擰(ning)下(xia)(xia)來,再(zai)輕(qing)輕(qing)把聯軸器(qi)(qi)的一(yi)半從軸上(shang)慢(man)慢(man)拉(la)下(xia)(xia),注意不要掉了(le),再(zai)用梅花扳手擰(ning)下(xia)(xia)泵(beng)軸吊緊螺(luo)(luo)栓和擋塊,讓葉輪(lun)慢(man)慢(man)下(xia)(xia)沉至泵(beng)體,然后拆(chai)下(xia)(xia)另(ling)外一(yi)半聯軸器(qi)(qi),拿(na)下(xia)(xia)泵(beng)軸擋圈(quan)。
拆卸湟中機械密封:抓(zhua)住密封彈簧順著泵(beng)軸往(wang)上提(ti),就能拆下來了(le)。
拆卸(xie)并(bing)清洗(xi)軸(zhou)(zhou)承座:先輕輕松動(dong)一(yi)下(xia)軸(zhou)(zhou)承座后用拆卸(xie)螺栓頂起軸(zhou)(zhou)承座,并(bing)且沿著泵軸(zhou)(zhou)往上提(ti)而(er)卸(xie)下(xia),再(zai)用噴氣(qi)燃料清洗(xi)軸(zhou)(zhou)承及座,裝前晾干(gan)并(bing)涂抹少許20號機械油用來潤(run)滑保護。
拆密(mi)封座:擰下(xia)密(mi)封座壓(ya)緊螺母,輕輕卸下(xia)密(mi)封座并清洗。
湟中機械密封裝(zhuang)配:在(zai)動、靜環(huan)鏡面上涂一層潔凈的20號潤(run)滑(hua)(hua)油,導軸(zhou)(zhou)承座(zuo)也抹上潤(run)滑(hua)(hua)油,先把(ba)靜環(huan)輕(qing)輕(qing)定(ding)位(wei)裝(zhuang)入(ru)導軸(zhou)(zhou)承座(zuo),再在(zai)泵(beng)軸(zhou)(zhou)上抹上潤(run)滑(hua)(hua)油,把(ba)動環(huan)部(bu)(bu)分輕(qing)輕(qing)裝(zhuang)入(ru)泵(beng)軸(zhou)(zhou)上,用手輕(qing)推密封環(huan)應(ying)能伸(shen)縮自如,注意動、靜環(huan)部(bu)(bu)分的防轉部(bu)(bu)位(wei)需裝(zhuang)配到位(wei)。
裝聯(lian)(lian)軸(zhou)器(qi):在電(dian)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),再在泵軸(zhou)端(duan)和聯(lian)(lian)軸(zhou)器(qi)槽內裝上(shang)(shang)擋(dang)塊并(bing)用梅花(hua)扳手擰(ning)緊(jin)螺(luo)栓(shuan);再裝上(shang)(shang)另(ling)一半(ban)聯(lian)(lian)軸(zhou)器(qi)擰(ning)上(shang)(shang)內六角螺(luo)釘。安裝聯(lian)(lian)軸(zhou)器(qi)正確(que)的檢查(cha)要(yao)求(qiu):對(dui)分(fen)式(shi)聯(lian)(lian)軸(zhou)器(qi)上(shang)(shang)下(xia)間隙需(xu)要(yao)均勻,用手盤動聯(lian)(lian)軸(zhou)器(qi)幾圈檢查(cha)轉動的靈活性(xing)。
裝(zhuang)(zhuang)密(mi)封座:先將密(mi)封座裝(zhuang)(zhuang)入橡膠(jiao)油封,再把(ba)密(mi)封座裝(zhuang)(zhuang)入泵(beng)蓋(gai)(gai)(gai)并壓(ya)在(zai)軸承座上,擰緊(jin)(jin)(jin)螺(luo)母,確保所(suo)有安裝(zhuang)(zhuang)螺(luo)釘(ding)(ding)緊(jin)(jin)(jin)固。當(dang)安裝(zhuang)(zhuang)螺(luo)釘(ding)(ding)被(bei)用作密(mi)封與(yu)軸之(zhi)間(jian)的(de)(de)驅動時,軸應打埋頭孔來加固連接,緊(jin)(jin)(jin)固壓(ya)蓋(gai)(gai)(gai)螺(luo)栓時應該平穩緊(jin)(jin)(jin)固,并且(qie)不要使壓(ya)蓋(gai)(gai)(gai)受彈力(li)。在(zai)可(ke)能的(de)(de)地(di)方使用4個以上螺(luo)釘(ding)(ding)的(de)(de)等間(jian)距壓(ya)蓋(gai)(gai)(gai),緊(jin)(jin)(jin)固壓(ya)蓋(gai)(gai)(gai)螺(luo)栓時,用塞尺檢查軸與(yu)壓(ya)蓋(gai)(gai)(gai)之(zhi)間(jian)的(de)(de)間(jian)隙(xi),這(zhe)在(zai)密(mi)封腔(qiang)對(dui)壓(ya)蓋(gai)(gai)(gai)不導(dao)向時,顯得特別重要,因為壓(ya)蓋(gai)(gai)(gai)必須對(dui)中。
