莒縣如何對機械密封進行更換工作

發布時間:2021-06-01 15:17:49 人氣:172599 來(lai)源(yuan):川工密(mi)封

  莒縣機械密封利用機(ji)械方式(shi)傳(chuan)遞動(dong)(dong)(dong)(dong)(dong)力(li)和運動(dong)(dong)(dong)(dong)(dong)的(de)傳(chuan)動(dong)(dong)(dong)(dong)(dong),機(ji)械傳(chuan)動(dong)(dong)(dong)(dong)(dong)在機(ji)械工程中應用非常廣(guang)泛,有多種形式(shi),主(zhu)要(yao)包括皮帶傳(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)傳(chuan)動(dong)(dong)(dong)(dong)(dong)、鏈(lian)傳(chuan)動(dong)(dong)(dong)(dong)(dong)、蝸(gua)桿蝸(gua)輪(lun)傳(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)齒(chi)條傳(chuan)動(dong)(dong)(dong)(dong)(dong)和螺旋傳(chuan)動(dong)(dong)(dong)(dong)(dong)等。齒(chi)輪(lun)傳(chuan)動(dong)(dong)(dong)(dong)(dong)能夠用于大功率(lv)的(de)場合,傳(chuan)動(dong)(dong)(dong)(dong)(dong)比準確(que),但(dan)一(yi)般要(yao)求較高的(de)制造精(jing)度和安(an)裝精(jing)度。還有一(yi)類(lei)是靠機(ji)件間的(de)摩擦力(li)傳(chuan)遞動(dong)(dong)(dong)(dong)(dong)力(li)和運動(dong)(dong)(dong)(dong)(dong)的(de)摩擦傳(chuan)動(dong)(dong)(dong)(dong)(dong),包括帶傳(chuan)動(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)動(dong)(dong)(dong)(dong)(dong)和摩擦輪(lun)傳(chuan)動(dong)(dong)(dong)(dong)(dong)等。摩擦傳(chuan)動(dong)(dong)(dong)(dong)(dong)容(rong)易實現(xian)無級變速(su),可以適(shi)應軸間距較大的(de)傳(chuan)動(dong)(dong)(dong)(dong)(dong)場合,而過載打(da)滑還能起到緩沖(chong)和保護傳(chuan)動(dong)(dong)(dong)(dong)(dong)裝置的(de)作用,但(dan)這種傳(chuan)動(dong)(dong)(dong)(dong)(dong)一(yi)般不能用于大功率(lv)的(de)場合,也不能保證準確(que)的(de)傳(chuan)動(dong)(dong)(dong)(dong)(dong)比。

  傳動形式多,但是莒縣機械密封的(de)更換工作大(da)同小異,首(shou)先拆(chai)前需確認(ren)電機處于(yu)檢(jian)修(xiu)狀態,擰下加油(you)螺塞,用吸管把(ba)密(mi)封座腔內的(de)潤滑油(you)吸出(chu)。準備好放(fang)置泵零件的(de)工作臺(tai)及拆(chai)裝工具,切勿任意亂放(fang)亂用,避免(mian)碰壞泵的(de)零部(bu)件。

  拆對(dui)分式(shi)聯(lian)軸器(qi)(qi):先把(ba)聯(lian)軸器(qi)(qi)的固定內六角(jiao)螺(luo)釘擰下(xia)來(lai),再(zai)輕(qing)輕(qing)把(ba)聯(lian)軸器(qi)(qi)的一半從軸上慢(man)慢(man)拉(la)下(xia),注意不(bu)要(yao)掉(diao)了(le),再(zai)用梅花扳手擰下(xia)泵(beng)(beng)軸吊緊螺(luo)栓和擋(dang)塊,讓葉輪慢(man)慢(man)下(xia)沉至泵(beng)(beng)體,然后拆下(xia)另外一半聯(lian)軸器(qi)(qi),拿下(xia)泵(beng)(beng)軸擋(dang)圈。

  拆卸莒縣機械密封:抓住密封彈簧(huang)順著泵軸往上提(ti),就能拆下來了。

  拆卸(xie)并(bing)(bing)清洗軸(zhou)承座:先輕(qing)輕(qing)松動(dong)一下軸(zhou)承座后用拆卸(xie)螺栓(shuan)頂起軸(zhou)承座,并(bing)(bing)且沿著泵軸(zhou)往上(shang)提而卸(xie)下,再用噴氣燃(ran)料清洗軸(zhou)承及座,裝前(qian)晾干并(bing)(bing)涂抹少許20號(hao)機械油用來(lai)潤(run)滑(hua)保護(hu)。

  拆密封(feng)座:擰下密封(feng)座壓緊螺母,輕輕卸下密封(feng)座并清(qing)洗。

  莒縣機械密封裝配:在(zai)動、靜環(huan)(huan)鏡面上(shang)(shang)涂一層潔凈的20號(hao)潤滑油(you)(you),導(dao)軸(zhou)(zhou)承座也抹上(shang)(shang)潤滑油(you)(you),先把靜環(huan)(huan)輕輕定位裝入導(dao)軸(zhou)(zhou)承座,再在(zai)泵(beng)軸(zhou)(zhou)上(shang)(shang)抹上(shang)(shang)潤滑油(you)(you),把動環(huan)(huan)部分輕輕裝入泵(beng)軸(zhou)(zhou)上(shang)(shang),用手(shou)輕推(tui)密封環(huan)(huan)應能伸縮自如,注(zhu)意動、靜環(huan)(huan)部分的防轉部位需裝配到位。

  裝聯(lian)(lian)軸(zhou)(zhou)器:在電機軸(zhou)(zhou)頭上(shang)裝上(shang)擋圈(quan),裝上(shang)一半聯(lian)(lian)軸(zhou)(zhou)器,再(zai)在泵軸(zhou)(zhou)端(duan)和聯(lian)(lian)軸(zhou)(zhou)器槽內裝上(shang)擋塊并(bing)用梅花扳手擰緊螺栓;再(zai)裝上(shang)另一半聯(lian)(lian)軸(zhou)(zhou)器擰上(shang)內六角螺釘(ding)。安裝聯(lian)(lian)軸(zhou)(zhou)器正(zheng)確的檢查要求:對分(fen)式聯(lian)(lian)軸(zhou)(zhou)器上(shang)下(xia)間隙需要均(jun)勻,用手盤動(dong)聯(lian)(lian)軸(zhou)(zhou)器幾(ji)圈(quan)檢查轉動(dong)的靈活性。

  裝密(mi)(mi)封(feng)座(zuo)(zuo):先將(jiang)密(mi)(mi)封(feng)座(zuo)(zuo)裝入橡膠油(you)封(feng),再把密(mi)(mi)封(feng)座(zuo)(zuo)裝入泵蓋(gai)(gai)并壓(ya)在軸承(cheng)座(zuo)(zuo)上(shang),擰緊螺(luo)(luo)母,確(que)保所有(you)安(an)(an)裝螺(luo)(luo)釘緊固(gu)。當安(an)(an)裝螺(luo)(luo)釘被用作密(mi)(mi)封(feng)與(yu)(yu)軸之(zhi)間(jian)(jian)的(de)驅動時,軸應打埋頭孔來(lai)加固(gu)連(lian)接,緊固(gu)壓(ya)蓋(gai)(gai)螺(luo)(luo)栓(shuan)時應該平穩緊固(gu),并且不(bu)要使壓(ya)蓋(gai)(gai)受彈力(li)。在可能的(de)地方使用4個以(yi)上(shang)螺(luo)(luo)釘的(de)等間(jian)(jian)距(ju)壓(ya)蓋(gai)(gai),緊固(gu)壓(ya)蓋(gai)(gai)螺(luo)(luo)栓(shuan)時,用塞尺檢查軸與(yu)(yu)壓(ya)蓋(gai)(gai)之(zhi)間(jian)(jian)的(de)間(jian)(jian)隙,這(zhe)在密(mi)(mi)封(feng)腔對壓(ya)蓋(gai)(gai)不(bu)導向(xiang)時,顯得(de)特別重要,因為壓(ya)蓋(gai)(gai)必(bi)須對中。
