太倉機械密封利用機(ji)械方式傳(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)力和(he)(he)運(yun)動(dong)(dong)(dong)(dong)(dong)的(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong),機(ji)械傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)在機(ji)械工程中應(ying)用非常廣泛,有多種形式,主要包括(kuo)皮帶(dai)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、蝸(gua)桿蝸(gua)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)(chi)輪(lun)齒(chi)(chi)條(tiao)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)(he)螺旋傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等。齒(chi)(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)能(neng)夠用于大(da)(da)功(gong)率的(de)場(chang)合(he),傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比準確,但一般要求較(jiao)高的(de)制(zhi)造精(jing)度和(he)(he)安(an)裝精(jing)度。還(huan)(huan)有一類是靠(kao)機(ji)件間的(de)摩(mo)擦(ca)(ca)力傳(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)力和(he)(he)運(yun)動(dong)(dong)(dong)(dong)(dong)的(de)摩(mo)擦(ca)(ca)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong),包括(kuo)帶(dai)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)(he)摩(mo)擦(ca)(ca)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等。摩(mo)擦(ca)(ca)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)容易實現無級變速(su),可以適應(ying)軸間距較(jiao)大(da)(da)的(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)場(chang)合(he),而(er)過載(zai)打滑還(huan)(huan)能(neng)起到(dao)緩沖和(he)(he)保護傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)裝置的(de)作用,但這種傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)一般不能(neng)用于大(da)(da)功(gong)率的(de)場(chang)合(he),也不能(neng)保證準確的(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比。
傳動形式多,但是太倉機械密封的(de)更換工(gong)作大同小異,首先拆前需確(que)認電機處于(yu)檢修狀態,擰下加油螺塞,用吸管把密封座(zuo)腔內的(de)潤滑油吸出。準備好放置泵(beng)零(ling)件的(de)工(gong)作臺(tai)及拆裝(zhuang)工(gong)具,切勿任意(yi)亂放亂用,避免(mian)碰壞泵(beng)的(de)零(ling)部件。
拆對分式(shi)聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi):先(xian)把聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)的固定內六角螺釘擰下(xia)(xia)來(lai),再輕輕把聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)的一(yi)半(ban)從軸(zhou)(zhou)(zhou)上慢(man)(man)(man)(man)慢(man)(man)(man)(man)拉(la)下(xia)(xia),注意(yi)不要掉了,再用梅花(hua)扳手擰下(xia)(xia)泵軸(zhou)(zhou)(zhou)吊緊螺栓(shuan)和擋塊,讓葉輪慢(man)(man)(man)(man)慢(man)(man)(man)(man)下(xia)(xia)沉(chen)至泵體,然后拆下(xia)(xia)另(ling)外一(yi)半(ban)聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi),拿(na)下(xia)(xia)泵軸(zhou)(zhou)(zhou)擋圈。
拆卸太倉機械密封:抓住密封彈簧順(shun)著泵軸往上提,就(jiu)能拆下(xia)來了(le)。
拆卸(xie)并清(qing)洗軸承座(zuo)(zuo):先輕輕松動一下軸承座(zuo)(zuo)后用(yong)拆卸(xie)螺栓頂(ding)起(qi)軸承座(zuo)(zuo),并且沿(yan)著泵(beng)軸往上提而卸(xie)下,再用(yong)噴氣燃料清(qing)洗軸承及座(zuo)(zuo),裝前(qian)晾干(gan)并涂抹少許20號(hao)機械油用(yong)來潤滑保護。
拆密(mi)封(feng)座:擰(ning)下(xia)密(mi)封(feng)座壓緊螺母(mu),輕輕卸下(xia)密(mi)封(feng)座并清洗。
太倉機械密封裝(zhuang)配:在(zai)(zai)動、靜環(huan)鏡面上(shang)涂一(yi)層(ceng)潔凈的20號潤滑油(you),導(dao)軸(zhou)(zhou)承座也(ye)抹(mo)上(shang)潤滑油(you),先把靜環(huan)輕(qing)(qing)輕(qing)(qing)定(ding)位(wei)(wei)裝(zhuang)入導(dao)軸(zhou)(zhou)承座,再在(zai)(zai)泵軸(zhou)(zhou)上(shang)抹(mo)上(shang)潤滑油(you),把動環(huan)部分(fen)輕(qing)(qing)輕(qing)(qing)裝(zhuang)入泵軸(zhou)(zhou)上(shang),用手輕(qing)(qing)推(tui)密封環(huan)應能伸縮自如,注意動、靜環(huan)部分(fen)的防轉部位(wei)(wei)需裝(zhuang)配到位(wei)(wei)。
裝聯(lian)軸(zhou)(zhou)(zhou)器(qi):在電機軸(zhou)(zhou)(zhou)頭上(shang)裝上(shang)擋(dang)圈(quan),裝上(shang)一(yi)半(ban)聯(lian)軸(zhou)(zhou)(zhou)器(qi),再在泵(beng)軸(zhou)(zhou)(zhou)端和聯(lian)軸(zhou)(zhou)(zhou)器(qi)槽內裝上(shang)擋(dang)塊(kuai)并(bing)用梅(mei)花扳手擰(ning)緊螺栓(shuan);再裝上(shang)另一(yi)半(ban)聯(lian)軸(zhou)(zhou)(zhou)器(qi)擰(ning)上(shang)內六角(jiao)螺釘。安(an)裝聯(lian)軸(zhou)(zhou)(zhou)器(qi)正確的(de)檢查(cha)要(yao)求:對分(fen)式聯(lian)軸(zhou)(zhou)(zhou)器(qi)上(shang)下間隙需要(yao)均(jun)勻,用手盤(pan)動聯(lian)軸(zhou)(zhou)(zhou)器(qi)幾圈(quan)檢查(cha)轉動的(de)靈活性。
裝(zhuang)密封(feng)座:先將密封(feng)座裝(zhuang)入橡膠油封(feng),再把(ba)密封(feng)座裝(zhuang)入泵蓋并(bing)壓(ya)在(zai)(zai)軸(zhou)(zhou)承座上,擰緊(jin)(jin)螺(luo)(luo)母,確保所有(you)安裝(zhuang)螺(luo)(luo)釘(ding)(ding)緊(jin)(jin)固(gu)。當安裝(zhuang)螺(luo)(luo)釘(ding)(ding)被用作(zuo)密封(feng)與軸(zhou)(zhou)之間(jian)的(de)(de)驅動時,軸(zhou)(zhou)應(ying)打埋頭孔來加固(gu)連接,緊(jin)(jin)固(gu)壓(ya)蓋螺(luo)(luo)栓時應(ying)該平穩緊(jin)(jin)固(gu),并(bing)且(qie)不要(yao)使(shi)壓(ya)蓋受(shou)彈力。在(zai)(zai)可(ke)能的(de)(de)地方(fang)使(shi)用4個以上螺(luo)(luo)釘(ding)(ding)的(de)(de)等間(jian)距壓(ya)蓋,緊(jin)(jin)固(gu)壓(ya)蓋螺(luo)(luo)栓時,用塞尺檢查軸(zhou)(zhou)與壓(ya)蓋之間(jian)的(de)(de)間(jian)隙,這在(zai)(zai)密封(feng)腔(qiang)對(dui)壓(ya)蓋不導向時,顯得特別重要(yao),因為壓(ya)蓋必須對(dui)中。
