　　傳動形式多，但是北海街道機械密封的(de)(de)更換工(gong)作(zuo)大同小(xiao)異，首先拆前需確認電機處于檢修狀態，擰(ning)下加油螺塞，用(yong)吸(xi)管(guan)把密封座腔內的(de)(de)潤滑(hua)油吸(xi)出。準(zhun)備好放置泵(beng)零(ling)(ling)件的(de)(de)工(gong)作(zuo)臺及拆裝工(gong)具，切勿任意亂放亂用(yong)，避免碰壞(huai)泵(beng)的(de)(de)零(ling)(ling)部(bu)件。

　　拆對分(fen)式聯軸(zhou)(zhou)器(qi)：先把聯軸(zhou)(zhou)器(qi)的固定內六角(jiao)螺(luo)釘(ding)擰(ning)下(xia)來(lai)，再輕(qing)輕(qing)把聯軸(zhou)(zhou)器(qi)的一半(ban)從軸(zhou)(zhou)上慢(man)慢(man)拉下(xia)，注意(yi)不要掉了，再用梅花(hua)扳手(shou)擰(ning)下(xia)泵(beng)軸(zhou)(zhou)吊緊螺(luo)栓和擋(dang)塊，讓葉輪慢(man)慢(man)下(xia)沉至泵(beng)體，然后拆下(xia)另外(wai)一半(ban)聯軸(zhou)(zhou)器(qi)，拿下(xia)泵(beng)軸(zhou)(zhou)擋(dang)圈。

　　拆卸北海街道機械密封：抓住密封(feng)彈簧順著泵(beng)軸(zhou)往上提，就能拆下(xia)來了。

　　拆卸(xie)(xie)并清(qing)洗軸(zhou)承(cheng)座：先輕輕松動(dong)一下軸(zhou)承(cheng)座后用拆卸(xie)(xie)螺栓頂起軸(zhou)承(cheng)座，并且沿著泵(beng)軸(zhou)往上提(ti)而卸(xie)(xie)下，再用噴氣燃料清(qing)洗軸(zhou)承(cheng)及座，裝前晾干(gan)并涂(tu)抹少許20號機械油用來潤滑保(bao)護。

　　拆密封座：擰下密封座壓緊(jin)螺母，輕(qing)(qing)輕(qing)(qing)卸下密封座并(bing)清洗。

　　北海街道機械密封裝配：在動、靜環(huan)(huan)(huan)(huan)鏡面上涂一(yi)層(ceng)潔凈的20號潤滑油，導軸(zhou)承(cheng)(cheng)座也(ye)抹上潤滑油，先(xian)把靜環(huan)(huan)(huan)(huan)輕輕定(ding)位裝入導軸(zhou)承(cheng)(cheng)座，再在泵(beng)(beng)軸(zhou)上抹上潤滑油，把動環(huan)(huan)(huan)(huan)部分(fen)輕輕裝入泵(beng)(beng)軸(zhou)上，用手輕推密封環(huan)(huan)(huan)(huan)應能(neng)伸(shen)縮自如，注(zhu)意動、靜環(huan)(huan)(huan)(huan)部分(fen)的防轉部位需裝配到位。

　　裝(zhuang)聯軸(zhou)(zhou)(zhou)器(qi)：在(zai)電(dian)機軸(zhou)(zhou)(zhou)頭上裝(zhuang)上擋圈，裝(zhuang)上一半聯軸(zhou)(zhou)(zhou)器(qi)，再在(zai)泵軸(zhou)(zhou)(zhou)端和聯軸(zhou)(zhou)(zhou)器(qi)槽內裝(zhuang)上擋塊并用(yong)梅花扳(ban)手擰(ning)緊螺(luo)(luo)栓(shuan)；再裝(zhuang)上另(ling)一半聯軸(zhou)(zhou)(zhou)器(qi)擰(ning)上內六角螺(luo)(luo)釘。安裝(zhuang)聯軸(zhou)(zhou)(zhou)器(qi)正確的(de)檢查(cha)要求：對分式聯軸(zhou)(zhou)(zhou)器(qi)上下(xia)間隙需要均勻，用(yong)手盤動聯軸(zhou)(zhou)(zhou)器(qi)幾圈檢查(cha)轉(zhuan)動的(de)靈活性。

　　裝(zhuang)密(mi)(mi)封座：先(xian)將密(mi)(mi)封座裝(zhuang)入橡膠油封，再(zai)把(ba)密(mi)(mi)封座裝(zhuang)入泵(beng)蓋(gai)并(bing)壓(ya)(ya)在軸承座上，擰緊(jin)螺(luo)(luo)母，確保所(suo)有安裝(zhuang)螺(luo)(luo)釘緊(jin)固(gu)。當(dang)安裝(zhuang)螺(luo)(luo)釘被用作密(mi)(mi)封與軸之(zhi)(zhi)間的驅(qu)動時(shi)，軸應打埋頭(tou)孔來加固(gu)連接(jie)，緊(jin)固(gu)壓(ya)(ya)蓋(gai)螺(luo)(luo)栓時(shi)應該平穩(wen)緊(jin)固(gu)，并(bing)且不(bu)(bu)要使壓(ya)(ya)蓋(gai)受彈力。在可能的地方使用4個以上螺(luo)(luo)釘的等間距壓(ya)(ya)蓋(gai)，緊(jin)固(gu)壓(ya)(ya)蓋(gai)螺(luo)(luo)栓時(shi)，用塞尺檢查軸與壓(ya)(ya)蓋(gai)之(zhi)(zhi)間的間隙(xi)，這在密(mi)(mi)封腔對(dui)壓(ya)(ya)蓋(gai)不(bu)(bu)導向時(shi)，顯得特別重要，因為壓(ya)(ya)蓋(gai)必須對(dui)中。
