傳動形式多,但是吳興機械密封的(de)更換工(gong)作大同小異,首先拆前需確認電機處于檢修狀態,擰下加油(you)螺塞,用(yong)吸(xi)管把(ba)密(mi)封座腔內的(de)潤滑油(you)吸(xi)出(chu)。準備好放(fang)置泵零(ling)件的(de)工(gong)作臺及拆裝(zhuang)工(gong)具,切勿(wu)任意(yi)亂(luan)(luan)放(fang)亂(luan)(luan)用(yong),避免碰壞泵的(de)零(ling)部件。
拆對(dui)分式聯軸(zhou)器(qi)(qi)(qi):先(xian)把(ba)聯軸(zhou)器(qi)(qi)(qi)的固定內六角螺釘擰下(xia)來,再輕(qing)(qing)輕(qing)(qing)把(ba)聯軸(zhou)器(qi)(qi)(qi)的一(yi)半(ban)從軸(zhou)上慢(man)慢(man)拉下(xia),注意不要掉了,再用梅花扳手擰下(xia)泵(beng)軸(zhou)吊緊螺栓和擋(dang)塊,讓葉輪慢(man)慢(man)下(xia)沉至(zhi)泵(beng)體,然后拆下(xia)另外一(yi)半(ban)聯軸(zhou)器(qi)(qi)(qi),拿下(xia)泵(beng)軸(zhou)擋(dang)圈。
拆卸吳興機械密封:抓住密封(feng)彈簧順著泵(beng)軸往上提,就能拆下來(lai)了(le)。
拆(chai)卸并清洗軸(zhou)(zhou)承(cheng)座(zuo):先(xian)輕輕松動一下軸(zhou)(zhou)承(cheng)座(zuo)后用(yong)拆(chai)卸螺栓(shuan)頂起(qi)軸(zhou)(zhou)承(cheng)座(zuo),并且沿著泵軸(zhou)(zhou)往上提而卸下,再用(yong)噴氣燃料清洗軸(zhou)(zhou)承(cheng)及(ji)座(zuo),裝前晾干并涂抹少許20號機(ji)械油用(yong)來潤滑保護。
拆密封(feng)(feng)座:擰下密封(feng)(feng)座壓緊螺母,輕輕卸下密封(feng)(feng)座并清洗。
吳興機械密封裝(zhuang)配(pei)(pei):在動、靜(jing)環(huan)(huan)鏡面上涂一層(ceng)潔凈的20號潤滑(hua)油,導軸承座也抹上潤滑(hua)油,先(xian)把(ba)靜(jing)環(huan)(huan)輕(qing)輕(qing)定(ding)位裝(zhuang)入(ru)導軸承座,再在泵軸上抹上潤滑(hua)油,把(ba)動環(huan)(huan)部(bu)分(fen)輕(qing)輕(qing)裝(zhuang)入(ru)泵軸上,用手輕(qing)推密封(feng)環(huan)(huan)應能伸縮(suo)自如,注意動、靜(jing)環(huan)(huan)部(bu)分(fen)的防轉部(bu)位需裝(zhuang)配(pei)(pei)到位。
裝(zhuang)(zhuang)聯(lian)軸器(qi):在(zai)電機軸頭上裝(zhuang)(zhuang)上擋圈,裝(zhuang)(zhuang)上一(yi)半聯(lian)軸器(qi),再(zai)在(zai)泵(beng)軸端和(he)聯(lian)軸器(qi)槽內(nei)裝(zhuang)(zhuang)上擋塊并用梅花扳(ban)手擰緊螺(luo)栓;再(zai)裝(zhuang)(zhuang)上另一(yi)半聯(lian)軸器(qi)擰上內(nei)六角螺(luo)釘。安裝(zhuang)(zhuang)聯(lian)軸器(qi)正確的檢(jian)查要(yao)求:對分式聯(lian)軸器(qi)上下間隙(xi)需(xu)要(yao)均勻,用手盤動聯(lian)軸器(qi)幾圈檢(jian)查轉(zhuan)動的靈活性。
裝(zhuang)密封座:先將密封座裝(zhuang)入(ru)橡膠油封,再(zai)把密封座裝(zhuang)入(ru)泵蓋(gai)(gai)并壓(ya)在軸(zhou)承座上,擰緊(jin)螺(luo)母,確保所有安裝(zhuang)螺(luo)釘緊(jin)固。當安裝(zhuang)螺(luo)釘被用作密封與軸(zhou)之(zhi)間的驅(qu)動時(shi),軸(zhou)應打埋頭孔來(lai)加固連(lian)接,緊(jin)固壓(ya)蓋(gai)(gai)螺(luo)栓時(shi)應該(gai)平穩緊(jin)固,并且(qie)不要使(shi)壓(ya)蓋(gai)(gai)受彈力。在可能的地(di)方(fang)使(shi)用4個(ge)以上螺(luo)釘的等間距壓(ya)蓋(gai)(gai),緊(jin)固壓(ya)蓋(gai)(gai)螺(luo)栓時(shi),用塞尺(chi)檢(jian)查軸(zhou)與壓(ya)蓋(gai)(gai)之(zhi)間的間隙(xi),這在密封腔對(dui)壓(ya)蓋(gai)(gai)不導向(xiang)時(shi),顯得特別重要,因為壓(ya)蓋(gai)(gai)必須對(dui)中。
