濱海機械密封利用機(ji)(ji)械方式傳(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)力和運動(dong)(dong)的(de)(de)(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong),機(ji)(ji)械傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)在機(ji)(ji)械工程中應(ying)用非常廣(guang)泛(fan),有多種形式,主(zhu)要包括(kuo)(kuo)皮帶(dai)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)、齒輪(lun)(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)、蝸桿蝸輪(lun)(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)、齒輪(lun)(lun)(lun)齒條傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)和螺(luo)旋傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)等。齒輪(lun)(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)能(neng)夠用于大功(gong)率的(de)(de)(de)場(chang)合,傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)比準確,但一(yi)(yi)般(ban)要求較(jiao)高的(de)(de)(de)制(zhi)造(zao)精度和安裝(zhuang)精度。還(huan)有一(yi)(yi)類(lei)是(shi)靠機(ji)(ji)件間的(de)(de)(de)摩(mo)擦(ca)(ca)(ca)力傳(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)力和運動(dong)(dong)的(de)(de)(de)摩(mo)擦(ca)(ca)(ca)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong),包括(kuo)(kuo)帶(dai)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)和摩(mo)擦(ca)(ca)(ca)輪(lun)(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)等。摩(mo)擦(ca)(ca)(ca)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)容易實現無(wu)級變速,可以適應(ying)軸(zhou)間距較(jiao)大的(de)(de)(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)場(chang)合,而過載打滑還(huan)能(neng)起到緩(huan)沖和保護傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)裝(zhuang)置(zhi)的(de)(de)(de)作用,但這種傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)一(yi)(yi)般(ban)不(bu)能(neng)用于大功(gong)率的(de)(de)(de)場(chang)合,也(ye)不(bu)能(neng)保證準確的(de)(de)(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)比。
傳動形式多,但是濱海機械密封的更換工(gong)(gong)作(zuo)大同(tong)小異,首(shou)先拆前需確(que)認電機處(chu)于檢修狀(zhuang)態,擰下加油(you)螺(luo)塞,用吸管(guan)把(ba)密封座腔內的潤滑油(you)吸出(chu)。準備(bei)好放(fang)置泵零(ling)件的工(gong)(gong)作(zuo)臺及拆裝工(gong)(gong)具,切勿(wu)任意亂放(fang)亂用,避免(mian)碰(peng)壞泵的零(ling)部件。
拆對分式聯(lian)(lian)軸器(qi):先(xian)把(ba)(ba)聯(lian)(lian)軸器(qi)的(de)固(gu)定內(nei)六(liu)角螺(luo)釘(ding)擰(ning)(ning)下(xia)(xia)來(lai),再輕輕把(ba)(ba)聯(lian)(lian)軸器(qi)的(de)一半從軸上慢(man)慢(man)拉(la)下(xia)(xia),注意不要掉了,再用(yong)梅花扳(ban)手擰(ning)(ning)下(xia)(xia)泵(beng)軸吊(diao)緊螺(luo)栓和擋塊,讓葉輪(lun)慢(man)慢(man)下(xia)(xia)沉至泵(beng)體,然后拆下(xia)(xia)另外一半聯(lian)(lian)軸器(qi),拿下(xia)(xia)泵(beng)軸擋圈(quan)。
拆卸濱海機械密封:抓住密封(feng)彈簧順著泵軸往上提,就(jiu)能拆下來了。
拆(chai)卸(xie)并清洗軸(zhou)承座(zuo):先輕(qing)輕(qing)松動一下軸(zhou)承座(zuo)后用拆(chai)卸(xie)螺栓頂起軸(zhou)承座(zuo),并且沿著泵軸(zhou)往上提而卸(xie)下,再用噴氣燃(ran)料清洗軸(zhou)承及座(zuo),裝前晾干并涂(tu)抹少(shao)許20號機(ji)械油用來潤滑(hua)保護。
拆(chai)密(mi)(mi)封(feng)座:擰下密(mi)(mi)封(feng)座壓緊螺母,輕輕卸下密(mi)(mi)封(feng)座并清洗。
濱海機械密封裝配(pei):在動(dong)、靜環鏡面上涂一層潔凈的20號潤滑(hua)油(you),導(dao)(dao)軸(zhou)承座也抹上潤滑(hua)油(you),先(xian)把(ba)靜環輕(qing)(qing)輕(qing)(qing)定位(wei)裝入導(dao)(dao)軸(zhou)承座,再在泵軸(zhou)上抹上潤滑(hua)油(you),把(ba)動(dong)環部分(fen)(fen)輕(qing)(qing)輕(qing)(qing)裝入泵軸(zhou)上,用手輕(qing)(qing)推(tui)密封環應能(neng)伸縮自如(ru),注意動(dong)、靜環部分(fen)(fen)的防(fang)轉(zhuan)部位(wei)需裝配(pei)到位(wei)。
裝(zhuang)聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi):在(zai)電(dian)機軸(zhou)(zhou)(zhou)頭上(shang)裝(zhuang)上(shang)擋圈,裝(zhuang)上(shang)一(yi)半(ban)聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi),再在(zai)泵軸(zhou)(zhou)(zhou)端和聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)槽內(nei)裝(zhuang)上(shang)擋塊并用梅花扳手擰(ning)緊螺(luo)栓;再裝(zhuang)上(shang)另一(yi)半(ban)聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)擰(ning)上(shang)內(nei)六角螺(luo)釘。安(an)裝(zhuang)聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)正確(que)的檢查要求:對分式(shi)聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)上(shang)下(xia)間隙需要均勻,用手盤動(dong)聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)幾圈檢查轉動(dong)的靈活性。
裝(zhuang)密封(feng)座(zuo):先將密封(feng)座(zuo)裝(zhuang)入橡膠油封(feng),再(zai)把密封(feng)座(zuo)裝(zhuang)入泵蓋(gai)并壓(ya)(ya)在(zai)(zai)軸(zhou)(zhou)承座(zuo)上(shang),擰緊螺(luo)(luo)(luo)母,確(que)保所有安裝(zhuang)螺(luo)(luo)(luo)釘(ding)(ding)緊固(gu)。當安裝(zhuang)螺(luo)(luo)(luo)釘(ding)(ding)被用作密封(feng)與(yu)軸(zhou)(zhou)之(zhi)間(jian)(jian)的驅動(dong)時(shi),軸(zhou)(zhou)應(ying)打埋(mai)頭孔來加固(gu)連接,緊固(gu)壓(ya)(ya)蓋(gai)螺(luo)(luo)(luo)栓時(shi)應(ying)該平穩緊固(gu),并且不要使壓(ya)(ya)蓋(gai)受彈力。在(zai)(zai)可(ke)能的地方(fang)使用4個以(yi)上(shang)螺(luo)(luo)(luo)釘(ding)(ding)的等間(jian)(jian)距(ju)壓(ya)(ya)蓋(gai),緊固(gu)壓(ya)(ya)蓋(gai)螺(luo)(luo)(luo)栓時(shi),用塞尺檢查(cha)軸(zhou)(zhou)與(yu)壓(ya)(ya)蓋(gai)之(zhi)間(jian)(jian)的間(jian)(jian)隙,這(zhe)在(zai)(zai)密封(feng)腔(qiang)對壓(ya)(ya)蓋(gai)不導向(xiang)時(shi),顯得(de)特別(bie)重要,因為壓(ya)(ya)蓋(gai)必須對中。
