平遠機械密封利用機械方式傳(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)(dong)力(li)和(he)運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong),機械傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)在機械工程中應用非(fei)常廣泛,有多種形式,主要包括(kuo)皮帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、齒(chi)(chi)輪(lun)(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、蝸桿蝸輪(lun)(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、齒(chi)(chi)輪(lun)(lun)齒(chi)(chi)條傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)和(he)螺旋傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)等。齒(chi)(chi)輪(lun)(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)能夠用于大(da)功率的(de)(de)(de)(de)場(chang)合,傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比準確,但(dan)一(yi)(yi)般要求較高的(de)(de)(de)(de)制造精度(du)和(he)安(an)裝精度(du)。還有一(yi)(yi)類是靠(kao)機件(jian)間的(de)(de)(de)(de)摩(mo)擦(ca)(ca)力(li)傳(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)(dong)力(li)和(he)運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)(de)摩(mo)擦(ca)(ca)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong),包括(kuo)帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)和(he)摩(mo)擦(ca)(ca)輪(lun)(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)等。摩(mo)擦(ca)(ca)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)容易實現無(wu)級變速,可以適應軸間距較大(da)的(de)(de)(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)場(chang)合,而過載打(da)滑還能起到緩沖(chong)和(he)保護傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)裝置的(de)(de)(de)(de)作用,但(dan)這種傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)一(yi)(yi)般不能用于大(da)功率的(de)(de)(de)(de)場(chang)合,也不能保證準確的(de)(de)(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比。
傳動形式多,但是平遠機械密封的(de)更換(huan)工(gong)作(zuo)大同小異(yi),首先拆(chai)前需確認電機處于檢(jian)修狀(zhuang)態(tai),擰下加油螺塞,用吸管把密封座(zuo)腔內(nei)的(de)潤滑(hua)油吸出(chu)。準備(bei)好(hao)放置泵零件(jian)的(de)工(gong)作(zuo)臺及拆(chai)裝(zhuang)工(gong)具,切(qie)勿(wu)任意亂(luan)放亂(luan)用,避免碰(peng)壞泵的(de)零部(bu)件(jian)。
拆對(dui)分式聯(lian)軸(zhou)器:先把聯(lian)軸(zhou)器的(de)固定內六角螺釘擰(ning)下(xia)(xia)來,再輕(qing)輕(qing)把聯(lian)軸(zhou)器的(de)一(yi)半(ban)從軸(zhou)上慢(man)慢(man)拉下(xia)(xia),注意(yi)不(bu)要掉(diao)了,再用梅花扳手擰(ning)下(xia)(xia)泵(beng)軸(zhou)吊緊螺栓和擋(dang)塊,讓葉輪慢(man)慢(man)下(xia)(xia)沉至泵(beng)體,然(ran)后拆下(xia)(xia)另外一(yi)半(ban)聯(lian)軸(zhou)器,拿下(xia)(xia)泵(beng)軸(zhou)擋(dang)圈。
拆卸平遠機械密封:抓住(zhu)密(mi)封彈簧順(shun)著泵軸往上(shang)提,就(jiu)能(neng)拆下來了。
拆卸并清(qing)(qing)洗(xi)軸(zhou)承座:先輕輕松動(dong)一(yi)下軸(zhou)承座后用拆卸螺栓頂起(qi)軸(zhou)承座,并且沿著(zhu)泵(beng)軸(zhou)往上提(ti)而卸下,再用噴氣(qi)燃料清(qing)(qing)洗(xi)軸(zhou)承及座,裝前晾干并涂抹少許20號機械(xie)油用來潤滑保護(hu)。
拆(chai)密(mi)封(feng)座:擰下密(mi)封(feng)座壓緊螺母,輕輕卸下密(mi)封(feng)座并清洗。
平遠機械密封裝(zhuang)配(pei):在(zai)動(dong)、靜環(huan)(huan)鏡(jing)面上(shang)涂一(yi)層潔凈的20號(hao)潤(run)滑油,導(dao)軸(zhou)承(cheng)座也抹(mo)(mo)上(shang)潤(run)滑油,先把靜環(huan)(huan)輕輕定位(wei)裝(zhuang)入導(dao)軸(zhou)承(cheng)座,再在(zai)泵軸(zhou)上(shang)抹(mo)(mo)上(shang)潤(run)滑油,把動(dong)環(huan)(huan)部分(fen)輕輕裝(zhuang)入泵軸(zhou)上(shang),用手輕推密(mi)封環(huan)(huan)應能(neng)伸縮自如,注意(yi)動(dong)、靜環(huan)(huan)部分(fen)的防(fang)轉部位(wei)需裝(zhuang)配(pei)到位(wei)。
裝(zhuang)聯(lian)(lian)軸(zhou)(zhou)器(qi):在電(dian)機(ji)軸(zhou)(zhou)頭上(shang)裝(zhuang)上(shang)擋(dang)圈,裝(zhuang)上(shang)一(yi)半聯(lian)(lian)軸(zhou)(zhou)器(qi),再在泵軸(zhou)(zhou)端和聯(lian)(lian)軸(zhou)(zhou)器(qi)槽內裝(zhuang)上(shang)擋(dang)塊并(bing)用梅花扳手擰緊螺(luo)栓;再裝(zhuang)上(shang)另一(yi)半聯(lian)(lian)軸(zhou)(zhou)器(qi)擰上(shang)內六(liu)角螺(luo)釘。安裝(zhuang)聯(lian)(lian)軸(zhou)(zhou)器(qi)正(zheng)確(que)的檢查要求(qiu):對(dui)分式聯(lian)(lian)軸(zhou)(zhou)器(qi)上(shang)下間(jian)隙需要均勻,用手盤動聯(lian)(lian)軸(zhou)(zhou)器(qi)幾圈檢查轉動的靈活(huo)性。
裝(zhuang)(zhuang)(zhuang)(zhuang)密(mi)封座:先將(jiang)密(mi)封座裝(zhuang)(zhuang)(zhuang)(zhuang)入橡膠(jiao)油封,再把密(mi)封座裝(zhuang)(zhuang)(zhuang)(zhuang)入泵蓋(gai)并壓(ya)(ya)在(zai)軸(zhou)(zhou)承座上,擰緊(jin)螺(luo)母,確保所有安(an)裝(zhuang)(zhuang)(zhuang)(zhuang)螺(luo)釘緊(jin)固。當安(an)裝(zhuang)(zhuang)(zhuang)(zhuang)螺(luo)釘被用作(zuo)密(mi)封與軸(zhou)(zhou)之間的驅(qu)動(dong)時,軸(zhou)(zhou)應打埋(mai)頭孔來(lai)加固連接,緊(jin)固壓(ya)(ya)蓋(gai)螺(luo)栓(shuan)時應該平穩緊(jin)固,并且(qie)不要使壓(ya)(ya)蓋(gai)受彈力。在(zai)可能(neng)的地方使用4個以上螺(luo)釘的等間距壓(ya)(ya)蓋(gai),緊(jin)固壓(ya)(ya)蓋(gai)螺(luo)栓(shuan)時,用塞尺檢查軸(zhou)(zhou)與壓(ya)(ya)蓋(gai)之間的間隙,這在(zai)密(mi)封腔對壓(ya)(ya)蓋(gai)不導向時,顯(xian)得特(te)別(bie)重要,因為壓(ya)(ya)蓋(gai)必(bi)須對中。
