傳動形式多,但是麗江機械密封的(de)更(geng)換工(gong)作(zuo)大同小異,首先拆(chai)前需確認電機處(chu)于檢(jian)修狀態,擰下加油螺塞,用吸管把密封座腔內的(de)潤滑(hua)油吸出。準備好(hao)放置泵零件的(de)工(gong)作(zuo)臺及拆(chai)裝工(gong)具,切(qie)勿任意亂放亂用,避免碰(peng)壞泵的(de)零部件。
拆對分式聯(lian)軸(zhou)器:先(xian)把聯(lian)軸(zhou)器的固定內六角螺釘(ding)擰(ning)下(xia)(xia)(xia)來,再(zai)輕輕把聯(lian)軸(zhou)器的一半從軸(zhou)上慢(man)(man)慢(man)(man)拉下(xia)(xia)(xia),注意不要掉了,再(zai)用梅(mei)花扳手擰(ning)下(xia)(xia)(xia)泵(beng)軸(zhou)吊緊螺栓和擋塊,讓葉(xie)輪慢(man)(man)慢(man)(man)下(xia)(xia)(xia)沉至泵(beng)體,然(ran)后拆下(xia)(xia)(xia)另外一半聯(lian)軸(zhou)器,拿下(xia)(xia)(xia)泵(beng)軸(zhou)擋圈(quan)。
拆卸麗江機械密封:抓住(zhu)密封彈簧(huang)順著泵軸往上(shang)提,就(jiu)能(neng)拆(chai)下來了。
拆(chai)卸并清(qing)洗軸(zhou)承座(zuo):先輕輕松(song)動一下(xia)軸(zhou)承座(zuo)后用拆(chai)卸螺(luo)栓頂(ding)起軸(zhou)承座(zuo),并且沿著泵軸(zhou)往上提而(er)卸下(xia),再(zai)用噴氣燃料清(qing)洗軸(zhou)承及座(zuo),裝前晾(liang)干(gan)并涂抹少(shao)許20號機械油用來潤滑保護。
拆密封座(zuo):擰下(xia)密封座(zuo)壓緊螺(luo)母(mu),輕輕卸下(xia)密封座(zuo)并清洗(xi)。
麗江機械密封裝配:在(zai)(zai)動(dong)、靜環(huan)鏡面(mian)上(shang)涂一層潔(jie)凈(jing)的(de)20號(hao)潤(run)滑(hua)油(you),導(dao)軸(zhou)承(cheng)座也抹上(shang)潤(run)滑(hua)油(you),先(xian)把(ba)靜環(huan)輕(qing)輕(qing)定(ding)位裝入導(dao)軸(zhou)承(cheng)座,再在(zai)(zai)泵軸(zhou)上(shang)抹上(shang)潤(run)滑(hua)油(you),把(ba)動(dong)環(huan)部(bu)分輕(qing)輕(qing)裝入泵軸(zhou)上(shang),用手輕(qing)推密封(feng)環(huan)應能伸縮(suo)自如,注(zhu)意(yi)動(dong)、靜環(huan)部(bu)分的(de)防轉部(bu)位需裝配到位。
裝(zhuang)聯軸(zhou)(zhou)器(qi)(qi):在電機軸(zhou)(zhou)頭上裝(zhuang)上擋圈(quan),裝(zhuang)上一(yi)半聯軸(zhou)(zhou)器(qi)(qi),再(zai)在泵軸(zhou)(zhou)端和聯軸(zhou)(zhou)器(qi)(qi)槽(cao)內裝(zhuang)上擋塊并(bing)用梅花扳手擰(ning)(ning)緊螺栓;再(zai)裝(zhuang)上另一(yi)半聯軸(zhou)(zhou)器(qi)(qi)擰(ning)(ning)上內六角(jiao)螺釘。安(an)裝(zhuang)聯軸(zhou)(zhou)器(qi)(qi)正確的檢查(cha)要求(qiu):對分式聯軸(zhou)(zhou)器(qi)(qi)上下間隙需要均(jun)勻(yun),用手盤(pan)動聯軸(zhou)(zhou)器(qi)(qi)幾圈(quan)檢查(cha)轉動的靈活(huo)性。
裝(zhuang)(zhuang)密封座(zuo):先(xian)將密封座(zuo)裝(zhuang)(zhuang)入(ru)(ru)橡(xiang)膠(jiao)油(you)封,再(zai)把密封座(zuo)裝(zhuang)(zhuang)入(ru)(ru)泵蓋并壓(ya)在軸承座(zuo)上(shang),擰緊螺(luo)(luo)母,確保(bao)所有(you)安裝(zhuang)(zhuang)螺(luo)(luo)釘(ding)(ding)(ding)緊固。當安裝(zhuang)(zhuang)螺(luo)(luo)釘(ding)(ding)(ding)被(bei)用作(zuo)密封與軸之間(jian)的(de)驅動時(shi),軸應(ying)打埋頭(tou)孔來加固連接,緊固壓(ya)蓋螺(luo)(luo)栓時(shi)應(ying)該平穩(wen)緊固,并且(qie)不(bu)要使壓(ya)蓋受彈(dan)力。在可(ke)能的(de)地方使用4個以上(shang)螺(luo)(luo)釘(ding)(ding)(ding)的(de)等(deng)間(jian)距壓(ya)蓋,緊固壓(ya)蓋螺(luo)(luo)栓時(shi),用塞尺檢查軸與壓(ya)蓋之間(jian)的(de)間(jian)隙,這(zhe)在密封腔對壓(ya)蓋不(bu)導向時(shi),顯得特別重要,因為壓(ya)蓋必須對中。
