　　傳動形式多，但是房縣機械密封的更換工(gong)作(zuo)大同(tong)小異，首先拆前需確(que)認電機(ji)處(chu)于檢修狀態，擰(ning)下加(jia)油(you)螺塞，用(yong)吸(xi)管把(ba)密封座(zuo)腔內的潤滑油(you)吸(xi)出。準備好放(fang)置泵零(ling)件的工(gong)作(zuo)臺及(ji)拆裝工(gong)具，切勿任(ren)意亂放(fang)亂用(yong)，避免碰壞泵的零(ling)部(bu)件。

　　拆對分式聯軸(zhou)(zhou)器：先把(ba)聯軸(zhou)(zhou)器的固定內六角螺(luo)釘擰下(xia)(xia)(xia)來，再輕輕把(ba)聯軸(zhou)(zhou)器的一半(ban)從(cong)軸(zhou)(zhou)上慢慢拉(la)下(xia)(xia)(xia)，注意不要掉了，再用梅花扳(ban)手擰下(xia)(xia)(xia)泵(beng)軸(zhou)(zhou)吊緊螺(luo)栓(shuan)和擋塊，讓葉輪(lun)慢慢下(xia)(xia)(xia)沉至泵(beng)體，然后拆下(xia)(xia)(xia)另外一半(ban)聯軸(zhou)(zhou)器，拿(na)下(xia)(xia)(xia)泵(beng)軸(zhou)(zhou)擋圈。

　　拆卸房縣機械密封：抓住密封(feng)彈(dan)簧順著泵軸往(wang)上提(ti)，就能拆(chai)下(xia)來了(le)。

　　拆卸并清洗軸承(cheng)(cheng)(cheng)座(zuo)：先輕輕松動一(yi)下軸承(cheng)(cheng)(cheng)座(zuo)后(hou)用拆卸螺栓頂起軸承(cheng)(cheng)(cheng)座(zuo)，并且沿(yan)著泵軸往(wang)上提而卸下，再用噴氣燃料清洗軸承(cheng)(cheng)(cheng)及座(zuo)，裝前晾干并涂抹少(shao)許(xu)20號機械油用來潤滑(hua)保護(hu)。

　　拆(chai)密(mi)封座(zuo)：擰下密(mi)封座(zuo)壓緊螺母(mu)，輕(qing)(qing)輕(qing)(qing)卸下密(mi)封座(zuo)并(bing)清(qing)洗(xi)。

　　房縣機械密封裝配(pei)：在(zai)(zai)動、靜(jing)(jing)環(huan)(huan)鏡面(mian)上(shang)涂(tu)一(yi)層潔凈(jing)的20號潤(run)滑(hua)油，導軸承(cheng)座也抹上(shang)潤(run)滑(hua)油，先把靜(jing)(jing)環(huan)(huan)輕輕定位(wei)裝入導軸承(cheng)座，再在(zai)(zai)泵軸上(shang)抹上(shang)潤(run)滑(hua)油，把動環(huan)(huan)部分(fen)輕輕裝入泵軸上(shang)，用手輕推密(mi)封環(huan)(huan)應能伸縮自如，注意動、靜(jing)(jing)環(huan)(huan)部分(fen)的防轉部位(wei)需裝配(pei)到(dao)位(wei)。

　　裝(zhuang)(zhuang)聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)：在電機軸(zhou)(zhou)(zhou)(zhou)頭上(shang)(shang)裝(zhuang)(zhuang)上(shang)(shang)擋圈(quan)(quan)，裝(zhuang)(zhuang)上(shang)(shang)一半聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)，再在泵軸(zhou)(zhou)(zhou)(zhou)端和聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)槽內(nei)裝(zhuang)(zhuang)上(shang)(shang)擋塊并用梅花扳手擰緊螺栓；再裝(zhuang)(zhuang)上(shang)(shang)另(ling)一半聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)擰上(shang)(shang)內(nei)六角螺釘。安裝(zhuang)(zhuang)聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)正確的(de)檢查要求：對分式聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)上(shang)(shang)下間隙需要均勻，用手盤(pan)動(dong)(dong)聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)幾圈(quan)(quan)檢查轉(zhuan)動(dong)(dong)的(de)靈活性(xing)。

　　裝密(mi)(mi)(mi)(mi)封(feng)(feng)座(zuo)：先將密(mi)(mi)(mi)(mi)封(feng)(feng)座(zuo)裝入橡膠油(you)封(feng)(feng)，再把密(mi)(mi)(mi)(mi)封(feng)(feng)座(zuo)裝入泵蓋(gai)并(bing)壓(ya)在(zai)軸承(cheng)座(zuo)上(shang)，擰緊螺(luo)(luo)母(mu)，確保所有安裝螺(luo)(luo)釘緊固(gu)。當安裝螺(luo)(luo)釘被用(yong)作(zuo)密(mi)(mi)(mi)(mi)封(feng)(feng)與軸之(zhi)間(jian)(jian)的(de)驅動時(shi)，軸應(ying)打埋頭孔(kong)來(lai)加(jia)固(gu)連接，緊固(gu)壓(ya)蓋(gai)螺(luo)(luo)栓時(shi)應(ying)該(gai)平穩(wen)緊固(gu)，并(bing)且不要使壓(ya)蓋(gai)受彈力(li)。在(zai)可能的(de)地方使用(yong)4個以上(shang)螺(luo)(luo)釘的(de)等間(jian)(jian)距(ju)壓(ya)蓋(gai)，緊固(gu)壓(ya)蓋(gai)螺(luo)(luo)栓時(shi)，用(yong)塞(sai)尺(chi)檢查軸與壓(ya)蓋(gai)之(zhi)間(jian)(jian)的(de)間(jian)(jian)隙(xi)，這(zhe)在(zai)密(mi)(mi)(mi)(mi)封(feng)(feng)腔對壓(ya)蓋(gai)不導向時(shi)，顯(xian)得特(te)別重要，因(yin)為壓(ya)蓋(gai)必須對中。
