連山機械密封利用(yong)(yong)機(ji)械(xie)方式傳(chuan)(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)(dong)力和(he)(he)(he)運動(dong)(dong)(dong)(dong)(dong)(dong)的傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong),機(ji)械(xie)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)在機(ji)械(xie)工程中應(ying)用(yong)(yong)非(fei)常廣泛,有(you)多種形式,主要包(bao)括皮帶(dai)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、齒(chi)(chi)輪傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、鏈(lian)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、蝸桿蝸輪傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、齒(chi)(chi)輪齒(chi)(chi)條傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)和(he)(he)(he)螺(luo)旋傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)等。齒(chi)(chi)輪傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)能夠用(yong)(yong)于(yu)(yu)大(da)功(gong)率(lv)的場(chang)合(he),傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比(bi)準(zhun)確,但一(yi)般(ban)(ban)要求較高(gao)的制造精度和(he)(he)(he)安裝精度。還有(you)一(yi)類是(shi)靠機(ji)件(jian)間的摩擦(ca)(ca)力傳(chuan)(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)(dong)力和(he)(he)(he)運動(dong)(dong)(dong)(dong)(dong)(dong)的摩擦(ca)(ca)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong),包(bao)括帶(dai)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)和(he)(he)(he)摩擦(ca)(ca)輪傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)等。摩擦(ca)(ca)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)容易實現無級變速,可(ke)以適應(ying)軸間距較大(da)的傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)場(chang)合(he),而(er)過載(zai)打滑還能起(qi)到緩(huan)沖和(he)(he)(he)保護傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)裝置的作(zuo)用(yong)(yong),但這種傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)一(yi)般(ban)(ban)不(bu)能用(yong)(yong)于(yu)(yu)大(da)功(gong)率(lv)的場(chang)合(he),也不(bu)能保證準(zhun)確的傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比(bi)。
傳動形式多,但是連山機械密封的(de)更換工(gong)作大同小(xiao)異,首(shou)先拆(chai)前需確認電機(ji)處于檢(jian)修狀(zhuang)態,擰下加油螺塞,用吸管把密封座(zuo)腔內的(de)潤滑油吸出。準備(bei)好放置泵零件的(de)工(gong)作臺及(ji)拆(chai)裝工(gong)具,切勿任意亂放亂用,避免碰壞泵的(de)零部件。
拆(chai)(chai)對分式(shi)聯(lian)軸(zhou)器(qi):先把(ba)聯(lian)軸(zhou)器(qi)的(de)固定內六(liu)角螺(luo)釘擰(ning)下(xia)來,再(zai)輕(qing)輕(qing)把(ba)聯(lian)軸(zhou)器(qi)的(de)一(yi)半(ban)從軸(zhou)上慢(man)慢(man)拉下(xia),注意不要掉了,再(zai)用梅花扳手擰(ning)下(xia)泵(beng)軸(zhou)吊緊螺(luo)栓和擋塊(kuai),讓葉輪(lun)慢(man)慢(man)下(xia)沉至(zhi)泵(beng)體(ti),然后拆(chai)(chai)下(xia)另(ling)外一(yi)半(ban)聯(lian)軸(zhou)器(qi),拿下(xia)泵(beng)軸(zhou)擋圈。
拆卸連山機械密封:抓住密封(feng)彈簧順著(zhu)泵軸往上提,就(jiu)能拆下來了。
拆卸并(bing)清洗(xi)軸(zhou)承座:先輕輕松(song)動一下軸(zhou)承座后(hou)用(yong)拆卸螺栓頂(ding)起軸(zhou)承座,并(bing)且沿著泵軸(zhou)往上(shang)提而卸下,再(zai)用(yong)噴氣燃料(liao)清洗(xi)軸(zhou)承及座,裝前晾(liang)干并(bing)涂(tu)抹少許20號機(ji)械油用(yong)來(lai)潤(run)滑保護。
拆密封座:擰下密封座壓(ya)緊(jin)螺(luo)母,輕輕卸下密封座并清(qing)洗。
連山機械密封裝配(pei):在(zai)(zai)動(dong)、靜(jing)環(huan)(huan)(huan)鏡(jing)面上(shang)涂一層潔凈的20號潤滑(hua)油,導(dao)軸承座也抹上(shang)潤滑(hua)油,先把靜(jing)環(huan)(huan)(huan)輕輕定位(wei)裝入導(dao)軸承座,再在(zai)(zai)泵軸上(shang)抹上(shang)潤滑(hua)油,把動(dong)環(huan)(huan)(huan)部(bu)(bu)分(fen)輕輕裝入泵軸上(shang),用手(shou)輕推(tui)密(mi)封環(huan)(huan)(huan)應(ying)能伸縮自如(ru),注意動(dong)、靜(jing)環(huan)(huan)(huan)部(bu)(bu)分(fen)的防轉部(bu)(bu)位(wei)需裝配(pei)到位(wei)。
裝聯(lian)軸(zhou)器:在電機軸(zhou)頭上(shang)(shang)裝上(shang)(shang)擋圈,裝上(shang)(shang)一(yi)半(ban)聯(lian)軸(zhou)器,再在泵軸(zhou)端和(he)聯(lian)軸(zhou)器槽內(nei)裝上(shang)(shang)擋塊并(bing)用梅花扳手(shou)擰緊螺(luo)栓;再裝上(shang)(shang)另一(yi)半(ban)聯(lian)軸(zhou)器擰上(shang)(shang)內(nei)六角螺(luo)釘。安裝聯(lian)軸(zhou)器正(zheng)確的檢(jian)查要(yao)求:對分式聯(lian)軸(zhou)器上(shang)(shang)下間隙需要(yao)均勻,用手(shou)盤動聯(lian)軸(zhou)器幾圈檢(jian)查轉(zhuan)動的靈活(huo)性。
裝(zhuang)(zhuang)密(mi)封(feng)(feng)座:先將密(mi)封(feng)(feng)座裝(zhuang)(zhuang)入橡膠油封(feng)(feng),再把密(mi)封(feng)(feng)座裝(zhuang)(zhuang)入泵蓋(gai)(gai)并壓(ya)(ya)(ya)(ya)在軸承座上,擰緊螺(luo)母,確保所有安(an)裝(zhuang)(zhuang)螺(luo)釘(ding)緊固(gu)。當安(an)裝(zhuang)(zhuang)螺(luo)釘(ding)被用(yong)作密(mi)封(feng)(feng)與軸之(zhi)間的(de)驅動時,軸應打埋頭(tou)孔來加固(gu)連接(jie),緊固(gu)壓(ya)(ya)(ya)(ya)蓋(gai)(gai)螺(luo)栓時應該(gai)平(ping)穩緊固(gu),并且不要使壓(ya)(ya)(ya)(ya)蓋(gai)(gai)受彈力。在可能的(de)地(di)方(fang)使用(yong)4個以上螺(luo)釘(ding)的(de)等間距(ju)壓(ya)(ya)(ya)(ya)蓋(gai)(gai),緊固(gu)壓(ya)(ya)(ya)(ya)蓋(gai)(gai)螺(luo)栓時,用(yong)塞尺(chi)檢查軸與壓(ya)(ya)(ya)(ya)蓋(gai)(gai)之(zhi)間的(de)間隙,這在密(mi)封(feng)(feng)腔(qiang)對(dui)壓(ya)(ya)(ya)(ya)蓋(gai)(gai)不導向時,顯得(de)特別重要,因為壓(ya)(ya)(ya)(ya)蓋(gai)(gai)必須對(dui)中。
