武鄉機械密封利用(yong)機(ji)械(xie)方(fang)式(shi)傳(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)力(li)和(he)運(yun)動(dong)(dong)(dong)的(de)(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)，機(ji)械(xie)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)在機(ji)械(xie)工(gong)程中(zhong)應(ying)用(yong)非常廣(guang)泛，有(you)多種(zhong)形式(shi)，主要(yao)(yao)包括皮帶傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、齒(chi)輪傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、蝸桿蝸輪傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、齒(chi)輪齒(chi)條(tiao)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)和(he)螺(luo)旋傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)等。齒(chi)輪傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)能夠用(yong)于(yu)大功率的(de)(de)場合(he)，傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)比準確，但一(yi)(yi)般(ban)要(yao)(yao)求較(jiao)高的(de)(de)制造(zao)精度和(he)安裝(zhuang)精度。還有(you)一(yi)(yi)類是靠(kao)機(ji)件間(jian)的(de)(de)摩擦(ca)力(li)傳(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)力(li)和(he)運(yun)動(dong)(dong)(dong)的(de)(de)摩擦(ca)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)，包括帶傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)和(he)摩擦(ca)輪傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)等。摩擦(ca)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)容易實現無(wu)級變速，可以適應(ying)軸(zhou)間(jian)距較(jiao)大的(de)(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)場合(he)，而過(guo)載打滑還能起(qi)到緩沖和(he)保(bao)護傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)裝(zhuang)置(zhi)的(de)(de)作用(yong)，但這種(zhong)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)一(yi)(yi)般(ban)不能用(yong)于(yu)大功率的(de)(de)場合(he)，也不能保(bao)證準確的(de)(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)比。

　　傳動形式多，但是武鄉機械密封的(de)(de)(de)(de)更換工作(zuo)大同(tong)小異，首先拆(chai)(chai)前(qian)需確(que)認電機處于(yu)檢(jian)修狀態，擰下加油(you)螺塞，用吸管(guan)把密封(feng)座(zuo)腔內的(de)(de)(de)(de)潤滑油(you)吸出。準(zhun)備好放置(zhi)泵零件的(de)(de)(de)(de)工作(zuo)臺及(ji)拆(chai)(chai)裝(zhuang)工具，切勿任意亂(luan)(luan)放亂(luan)(luan)用，避免(mian)碰壞泵的(de)(de)(de)(de)零部(bu)件。

　　拆對(dui)分式聯軸(zhou)器：先把聯軸(zhou)器的固定內六角(jiao)螺(luo)釘擰(ning)下來，再輕輕把聯軸(zhou)器的一半(ban)從軸(zhou)上(shang)慢(man)慢(man)拉(la)下，注意不要掉了，再用(yong)梅花扳(ban)手(shou)擰(ning)下泵(beng)軸(zhou)吊緊螺(luo)栓和擋(dang)(dang)塊，讓葉輪慢(man)慢(man)下沉至泵(beng)體，然后拆下另(ling)外一半(ban)聯軸(zhou)器，拿下泵(beng)軸(zhou)擋(dang)(dang)圈(quan)。

　　拆卸武鄉機械密封：抓住密封彈簧(huang)順(shun)著泵軸往上(shang)提，就能拆下來了。

　　拆卸并清(qing)洗軸承(cheng)(cheng)座(zuo)：先輕(qing)輕(qing)松動一下軸承(cheng)(cheng)座(zuo)后(hou)用(yong)拆卸螺(luo)栓頂起(qi)軸承(cheng)(cheng)座(zuo)，并且(qie)沿著泵軸往(wang)上提而卸下，再用(yong)噴氣燃料清(qing)洗軸承(cheng)(cheng)及座(zuo)，裝前晾(liang)干(gan)并涂抹少許(xu)20號機械油用(yong)來潤滑保護(hu)。

　　拆密(mi)(mi)封(feng)座：擰下密(mi)(mi)封(feng)座壓緊螺母，輕(qing)輕(qing)卸下密(mi)(mi)封(feng)座并清洗。

　　武鄉機械密封裝配：在動、靜環(huan)(huan)鏡(jing)面(mian)上(shang)(shang)(shang)涂(tu)一層潔凈的20號潤滑(hua)油，導軸承(cheng)座也抹上(shang)(shang)(shang)潤滑(hua)油，先(xian)把靜環(huan)(huan)輕(qing)輕(qing)定(ding)位裝入導軸承(cheng)座，再在泵(beng)軸上(shang)(shang)(shang)抹上(shang)(shang)(shang)潤滑(hua)油，把動環(huan)(huan)部(bu)分輕(qing)輕(qing)裝入泵(beng)軸上(shang)(shang)(shang)，用手輕(qing)推密封環(huan)(huan)應能伸(shen)縮(suo)自如(ru)，注意(yi)動、靜環(huan)(huan)部(bu)分的防轉部(bu)位需裝配到位。

　　裝(zhuang)(zhuang)聯軸(zhou)(zhou)器(qi)(qi)：在電機軸(zhou)(zhou)頭上裝(zhuang)(zhuang)上擋(dang)圈，裝(zhuang)(zhuang)上一(yi)半聯軸(zhou)(zhou)器(qi)(qi)，再在泵軸(zhou)(zhou)端和聯軸(zhou)(zhou)器(qi)(qi)槽內(nei)(nei)裝(zhuang)(zhuang)上擋(dang)塊并用(yong)梅花(hua)扳手擰(ning)緊螺(luo)(luo)栓；再裝(zhuang)(zhuang)上另一(yi)半聯軸(zhou)(zhou)器(qi)(qi)擰(ning)上內(nei)(nei)六(liu)角螺(luo)(luo)釘。安(an)裝(zhuang)(zhuang)聯軸(zhou)(zhou)器(qi)(qi)正確的(de)檢(jian)查要求(qiu)：對(dui)分式聯軸(zhou)(zhou)器(qi)(qi)上下間隙需要均勻，用(yong)手盤動(dong)聯軸(zhou)(zhou)器(qi)(qi)幾圈檢(jian)查轉動(dong)的(de)靈活性。

　　裝密(mi)封(feng)(feng)(feng)座(zuo)：先將密(mi)封(feng)(feng)(feng)座(zuo)裝入橡膠(jiao)油封(feng)(feng)(feng)，再(zai)把(ba)密(mi)封(feng)(feng)(feng)座(zuo)裝入泵(beng)蓋并壓(ya)(ya)在軸(zhou)承座(zuo)上(shang)，擰緊螺母，確保所有(you)安裝螺釘(ding)緊固(gu)。當安裝螺釘(ding)被(bei)用作密(mi)封(feng)(feng)(feng)與軸(zhou)之(zhi)間(jian)的(de)驅動時(shi)(shi)，軸(zhou)應打埋頭孔(kong)來(lai)加固(gu)連接，緊固(gu)壓(ya)(ya)蓋螺栓時(shi)(shi)應該平穩緊固(gu)，并且不要使(shi)壓(ya)(ya)蓋受(shou)彈力。在可能的(de)地(di)方使(shi)用4個以上(shang)螺釘(ding)的(de)等間(jian)距(ju)壓(ya)(ya)蓋，緊固(gu)壓(ya)(ya)蓋螺栓時(shi)(shi)，用塞尺(chi)檢查軸(zhou)與壓(ya)(ya)蓋之(zhi)間(jian)的(de)間(jian)隙，這(zhe)在密(mi)封(feng)(feng)(feng)腔對壓(ya)(ya)蓋不導向(xiang)時(shi)(shi)，顯得特別重要，因為壓(ya)(ya)蓋必須對中。
