孝感機械密封利用機械方式傳(chuan)(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)力(li)(li)和(he)(he)運動(dong)(dong)(dong)(dong)的(de)(de)(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong),機械傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)在機械工(gong)程中應用非常廣泛,有多種(zhong)形式,主要包括皮帶傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒輪(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、蝸(gua)桿蝸(gua)輪(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒輪(lun)(lun)齒條傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)(he)螺旋傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)等。齒輪(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)能夠用于(yu)大(da)功率的(de)(de)(de)場(chang)(chang)合,傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)比(bi)準(zhun)確,但一般(ban)要求較高的(de)(de)(de)制造精(jing)度(du)和(he)(he)安裝(zhuang)精(jing)度(du)。還有一類是靠機件間的(de)(de)(de)摩(mo)擦(ca)力(li)(li)傳(chuan)(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)力(li)(li)和(he)(he)運動(dong)(dong)(dong)(dong)的(de)(de)(de)摩(mo)擦(ca)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong),包括帶傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)(he)摩(mo)擦(ca)輪(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)等。摩(mo)擦(ca)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)容易(yi)實現(xian)無級變速,可以適應軸間距較大(da)的(de)(de)(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)場(chang)(chang)合,而過載打滑還能起到緩沖和(he)(he)保(bao)(bao)護(hu)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)裝(zhuang)置(zhi)的(de)(de)(de)作用,但這(zhe)種(zhong)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)一般(ban)不能用于(yu)大(da)功率的(de)(de)(de)場(chang)(chang)合,也不能保(bao)(bao)證準(zhun)確的(de)(de)(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)比(bi)。
傳動形式多,但是孝感機械密封的更(geng)換工作(zuo)大同小異,首先拆前需確認電(dian)機(ji)處于檢修(xiu)狀態,擰下加(jia)油(you)螺塞,用吸管把密封座腔(qiang)內的潤滑(hua)油(you)吸出。準備好放(fang)置泵零件(jian)的工作(zuo)臺及拆裝工具,切(qie)勿(wu)任意亂放(fang)亂用,避免碰壞泵的零部(bu)件(jian)。
拆對分(fen)式聯(lian)軸(zhou)器(qi):先(xian)把聯(lian)軸(zhou)器(qi)的固定內(nei)六角螺釘(ding)擰下(xia)來,再輕輕把聯(lian)軸(zhou)器(qi)的一(yi)半從軸(zhou)上(shang)慢(man)慢(man)拉下(xia),注意不要(yao)掉了,再用梅花扳手擰下(xia)泵(beng)(beng)(beng)軸(zhou)吊(diao)緊螺栓和擋塊,讓葉(xie)輪慢(man)慢(man)下(xia)沉(chen)至泵(beng)(beng)(beng)體,然后拆下(xia)另外(wai)一(yi)半聯(lian)軸(zhou)器(qi),拿下(xia)泵(beng)(beng)(beng)軸(zhou)擋圈。
拆卸孝感機械密封:抓住密封(feng)彈簧(huang)順著泵軸往上提,就能拆下來了。
拆(chai)卸并清(qing)洗軸(zhou)(zhou)承座:先(xian)輕輕松(song)動一(yi)下軸(zhou)(zhou)承座后用(yong)拆(chai)卸螺(luo)栓頂(ding)起軸(zhou)(zhou)承座,并且沿著泵軸(zhou)(zhou)往上提(ti)而卸下,再用(yong)噴氣燃料清(qing)洗軸(zhou)(zhou)承及座,裝前晾干并涂抹(mo)少許20號(hao)機(ji)械油用(yong)來(lai)潤(run)滑(hua)保護。
拆密(mi)(mi)(mi)封(feng)座(zuo):擰(ning)下密(mi)(mi)(mi)封(feng)座(zuo)壓緊螺(luo)母,輕輕卸下密(mi)(mi)(mi)封(feng)座(zuo)并清(qing)洗。
孝感機械密封裝配:在動、靜(jing)環(huan)鏡(jing)面上涂一層潔凈的20號潤(run)滑油,導(dao)軸承座(zuo)也抹(mo)上潤(run)滑油,先(xian)把靜(jing)環(huan)輕輕定位裝入(ru)導(dao)軸承座(zuo),再在泵(beng)(beng)軸上抹(mo)上潤(run)滑油,把動環(huan)部分輕輕裝入(ru)泵(beng)(beng)軸上,用手輕推密封(feng)環(huan)應(ying)能伸縮自如(ru),注意動、靜(jing)環(huan)部分的防轉部位需(xu)裝配到位。
裝(zhuang)(zhuang)聯(lian)(lian)(lian)軸(zhou)器:在電機軸(zhou)頭上(shang)(shang)(shang)裝(zhuang)(zhuang)上(shang)(shang)(shang)擋(dang)圈,裝(zhuang)(zhuang)上(shang)(shang)(shang)一(yi)半聯(lian)(lian)(lian)軸(zhou)器,再(zai)在泵軸(zhou)端(duan)和聯(lian)(lian)(lian)軸(zhou)器槽內裝(zhuang)(zhuang)上(shang)(shang)(shang)擋(dang)塊并用梅(mei)花(hua)扳手擰緊螺栓;再(zai)裝(zhuang)(zhuang)上(shang)(shang)(shang)另一(yi)半聯(lian)(lian)(lian)軸(zhou)器擰上(shang)(shang)(shang)內六(liu)角(jiao)螺釘。安(an)裝(zhuang)(zhuang)聯(lian)(lian)(lian)軸(zhou)器正確的(de)檢查要求:對分式(shi)聯(lian)(lian)(lian)軸(zhou)器上(shang)(shang)(shang)下間(jian)隙需要均勻(yun),用手盤(pan)動(dong)(dong)聯(lian)(lian)(lian)軸(zhou)器幾(ji)圈檢查轉(zhuan)動(dong)(dong)的(de)靈活性(xing)。
裝(zhuang)密封(feng)(feng)座:先將密封(feng)(feng)座裝(zhuang)入橡(xiang)膠油封(feng)(feng),再把密封(feng)(feng)座裝(zhuang)入泵蓋(gai)(gai)并壓(ya)(ya)(ya)在(zai)軸(zhou)承座上,擰緊螺(luo)(luo)(luo)母,確(que)保(bao)所有(you)安裝(zhuang)螺(luo)(luo)(luo)釘(ding)緊固(gu)。當安裝(zhuang)螺(luo)(luo)(luo)釘(ding)被(bei)用作密封(feng)(feng)與軸(zhou)之(zhi)間的驅動時,軸(zhou)應打埋頭孔來(lai)加固(gu)連接,緊固(gu)壓(ya)(ya)(ya)蓋(gai)(gai)螺(luo)(luo)(luo)栓時應該平(ping)穩緊固(gu),并且(qie)不(bu)要使(shi)壓(ya)(ya)(ya)蓋(gai)(gai)受彈力。在(zai)可能的地方使(shi)用4個(ge)以(yi)上螺(luo)(luo)(luo)釘(ding)的等間距壓(ya)(ya)(ya)蓋(gai)(gai),緊固(gu)壓(ya)(ya)(ya)蓋(gai)(gai)螺(luo)(luo)(luo)栓時,用塞(sai)尺檢查軸(zhou)與壓(ya)(ya)(ya)蓋(gai)(gai)之(zhi)間的間隙(xi),這在(zai)密封(feng)(feng)腔對(dui)壓(ya)(ya)(ya)蓋(gai)(gai)不(bu)導向時,顯得(de)特別重(zhong)要,因(yin)為壓(ya)(ya)(ya)蓋(gai)(gai)必須對(dui)中。
