寧波機械密封利用(yong)機械(xie)方式傳(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)(dong)力和(he)(he)運(yun)(yun)動(dong)(dong)(dong)(dong)(dong)(dong)的(de)(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)，機械(xie)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)在機械(xie)工程中(zhong)應用(yong)非(fei)常廣(guang)泛，有(you)多種(zhong)形式，主要(yao)包括皮帶(dai)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、齒(chi)輪傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、蝸桿蝸輪傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、齒(chi)輪齒(chi)條傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)和(he)(he)螺旋傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)等。齒(chi)輪傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)能夠用(yong)于(yu)大(da)功率(lv)的(de)(de)場合(he)，傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比準(zhun)確，但一(yi)般(ban)要(yao)求較高的(de)(de)制造(zao)精度(du)和(he)(he)安裝精度(du)。還有(you)一(yi)類是靠機件(jian)間的(de)(de)摩擦力傳(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)(dong)力和(he)(he)運(yun)(yun)動(dong)(dong)(dong)(dong)(dong)(dong)的(de)(de)摩擦傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)，包括帶(dai)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)和(he)(he)摩擦輪傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)等。摩擦傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)容易實現無級(ji)變(bian)速，可以適(shi)應軸(zhou)間距(ju)較大(da)的(de)(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)場合(he)，而(er)過載打(da)滑還能起到緩沖和(he)(he)保(bao)(bao)護傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)裝置(zhi)的(de)(de)作用(yong)，但這種(zhong)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)一(yi)般(ban)不能用(yong)于(yu)大(da)功率(lv)的(de)(de)場合(he)，也不能保(bao)(bao)證(zheng)準(zhun)確的(de)(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比。

　　傳動形式多，但是寧波機械密封的(de)更(geng)換(huan)工作大同小異，首先拆(chai)(chai)前需(xu)確認電機處于檢修狀態，擰下加(jia)油螺塞，用吸管把密封座腔內的(de)潤滑油吸出。準備好放置泵零件(jian)的(de)工作臺及拆(chai)(chai)裝工具，切勿任意(yi)亂(luan)放亂(luan)用，避(bi)免碰壞泵的(de)零部件(jian)。

　　拆(chai)對分式(shi)聯軸(zhou)器(qi)：先把聯軸(zhou)器(qi)的固定內(nei)六角螺釘擰(ning)下(xia)(xia)來，再輕輕把聯軸(zhou)器(qi)的一半從軸(zhou)上慢慢拉下(xia)(xia)，注意不(bu)要掉了，再用梅花扳手擰(ning)下(xia)(xia)泵(beng)軸(zhou)吊緊螺栓(shuan)和擋塊，讓(rang)葉輪慢慢下(xia)(xia)沉至(zhi)泵(beng)體，然后(hou)拆(chai)下(xia)(xia)另外(wai)一半聯軸(zhou)器(qi)，拿下(xia)(xia)泵(beng)軸(zhou)擋圈(quan)。

　　拆卸寧波機械密封：抓(zhua)住密(mi)封(feng)彈簧(huang)順(shun)著泵軸往上提，就能拆下來了(le)。

　　拆卸(xie)并(bing)清洗(xi)軸(zhou)承(cheng)座(zuo)(zuo)：先輕(qing)輕(qing)松動一下軸(zhou)承(cheng)座(zuo)(zuo)后用(yong)(yong)拆卸(xie)螺栓頂(ding)起軸(zhou)承(cheng)座(zuo)(zuo)，并(bing)且(qie)沿著泵軸(zhou)往上提而卸(xie)下，再用(yong)(yong)噴氣燃料(liao)清洗(xi)軸(zhou)承(cheng)及座(zuo)(zuo)，裝前(qian)晾干并(bing)涂抹(mo)少許20號機(ji)械油用(yong)(yong)來潤滑保(bao)護。

　　拆密封(feng)(feng)座：擰下密封(feng)(feng)座壓(ya)緊螺母(mu)，輕輕卸(xie)下密封(feng)(feng)座并清洗。

　　寧波機械密封裝(zhuang)(zhuang)配：在(zai)動、靜環鏡面上涂一層潔凈的20號潤(run)滑(hua)(hua)油，導軸(zhou)承座也抹上潤(run)滑(hua)(hua)油，先把(ba)靜環輕輕定位裝(zhuang)(zhuang)入導軸(zhou)承座，再在(zai)泵(beng)軸(zhou)上抹上潤(run)滑(hua)(hua)油，把(ba)動環部分輕輕裝(zhuang)(zhuang)入泵(beng)軸(zhou)上，用手(shou)輕推密(mi)封環應(ying)能伸縮自如，注意(yi)動、靜環部分的防轉部位需(xu)裝(zhuang)(zhuang)配到位。

　　裝(zhuang)聯(lian)軸(zhou)器：在電機軸(zhou)頭(tou)上(shang)(shang)(shang)裝(zhuang)上(shang)(shang)(shang)擋(dang)圈，裝(zhuang)上(shang)(shang)(shang)一半聯(lian)軸(zhou)器，再在泵軸(zhou)端和聯(lian)軸(zhou)器槽內(nei)裝(zhuang)上(shang)(shang)(shang)擋(dang)塊并用梅花(hua)扳手擰(ning)緊螺(luo)(luo)栓(shuan)；再裝(zhuang)上(shang)(shang)(shang)另一半聯(lian)軸(zhou)器擰(ning)上(shang)(shang)(shang)內(nei)六角(jiao)螺(luo)(luo)釘。安裝(zhuang)聯(lian)軸(zhou)器正確的檢(jian)(jian)查要求(qiu)：對分式聯(lian)軸(zhou)器上(shang)(shang)(shang)下(xia)間隙(xi)需要均勻，用手盤動(dong)聯(lian)軸(zhou)器幾圈檢(jian)(jian)查轉動(dong)的靈(ling)活性。

　　裝密封(feng)(feng)座(zuo)(zuo)：先(xian)將密封(feng)(feng)座(zuo)(zuo)裝入(ru)橡膠油封(feng)(feng)，再把密封(feng)(feng)座(zuo)(zuo)裝入(ru)泵(beng)蓋并壓(ya)在軸承座(zuo)(zuo)上，擰(ning)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(bei)用(yong)(yong)作密封(feng)(feng)與(yu)軸之間(jian)(jian)的(de)驅動時，軸應打埋頭孔來加固(gu)連接(jie)，緊固(gu)壓(ya)蓋螺(luo)(luo)栓時應該平穩緊固(gu)，并且不要使壓(ya)蓋受彈力。在可能的(de)地(di)方使用(yong)(yong)4個以上螺(luo)(luo)釘的(de)等間(jian)(jian)距壓(ya)蓋，緊固(gu)壓(ya)蓋螺(luo)(luo)栓時，用(yong)(yong)塞尺檢查軸與(yu)壓(ya)蓋之間(jian)(jian)的(de)間(jian)(jian)隙，這在密封(feng)(feng)腔(qiang)對壓(ya)蓋不導向時，顯得(de)特別重要，因為壓(ya)蓋必須對中。
