孝感機械密封利用機(ji)械(xie)方(fang)式傳(chuan)(chuan)(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)力和(he)運(yun)動(dong)(dong)(dong)的(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)，機(ji)械(xie)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)在機(ji)械(xie)工程中應(ying)用非常廣泛，有(you)(you)多種(zhong)形式，主要包括皮帶傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、齒(chi)輪傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、蝸桿(gan)蝸輪傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、齒(chi)輪齒(chi)條(tiao)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)和(he)螺旋傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)等(deng)。齒(chi)輪傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)能(neng)(neng)夠用于(yu)大功率的(de)場(chang)合，傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)比(bi)準(zhun)確，但(dan)一般要求(qiu)較高的(de)制造精度(du)和(he)安裝(zhuang)精度(du)。還(huan)有(you)(you)一類是(shi)靠機(ji)件間的(de)摩擦力傳(chuan)(chuan)(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)力和(he)運(yun)動(dong)(dong)(dong)的(de)摩擦傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)，包括帶傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)和(he)摩擦輪傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)等(deng)。摩擦傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)容易實現無(wu)級(ji)變速，可(ke)以適(shi)應(ying)軸間距較大的(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)場(chang)合，而(er)過(guo)載打滑(hua)還(huan)能(neng)(neng)起到緩沖和(he)保護傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)裝(zhuang)置的(de)作用，但(dan)這種(zhong)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)一般不能(neng)(neng)用于(yu)大功率的(de)場(chang)合，也不能(neng)(neng)保證準(zhun)確的(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)比(bi)。

　　傳動形式多，但是孝感機械密封的(de)更換工作(zuo)大(da)同小異(yi)，首先拆前需確認電機處于檢修狀(zhuang)態，擰下(xia)加油螺塞，用(yong)(yong)吸管把密封座(zuo)腔內的(de)潤滑油吸出。準備好放(fang)置(zhi)泵(beng)零件的(de)工作(zuo)臺及拆裝工具，切勿任意(yi)亂(luan)放(fang)亂(luan)用(yong)(yong)，避(bi)免(mian)碰壞(huai)泵(beng)的(de)零部件。

　　拆對分(fen)式(shi)聯(lian)軸器：先把聯(lian)軸器的(de)(de)固定(ding)內六角螺釘擰(ning)下來(lai)，再輕(qing)(qing)輕(qing)(qing)把聯(lian)軸器的(de)(de)一半從軸上慢慢拉(la)下，注意不要(yao)掉了(le)，再用(yong)梅花扳手(shou)擰(ning)下泵軸吊(diao)緊螺栓和擋(dang)塊，讓葉輪慢慢下沉(chen)至(zhi)泵體，然后拆下另外一半聯(lian)軸器，拿(na)下泵軸擋(dang)圈。

　　拆卸孝感機械密封：抓住密封(feng)彈簧順著泵軸(zhou)往上提，就能拆(chai)下來了(le)。

　　拆卸并清洗軸(zhou)承(cheng)座(zuo)：先(xian)輕(qing)輕(qing)松動一下(xia)軸(zhou)承(cheng)座(zuo)后用(yong)拆卸螺栓(shuan)頂起(qi)軸(zhou)承(cheng)座(zuo)，并且沿著泵軸(zhou)往上提(ti)而卸下(xia)，再用(yong)噴氣燃料清洗軸(zhou)承(cheng)及座(zuo)，裝前晾干并涂抹少(shao)許20號(hao)機械油用(yong)來潤(run)滑保護(hu)。

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

　　孝感機械密封裝(zhuang)配：在動(dong)、靜(jing)環(huan)(huan)鏡面(mian)上(shang)(shang)涂一層潔凈(jing)的20號潤(run)(run)滑(hua)油，導(dao)軸承座(zuo)(zuo)也抹上(shang)(shang)潤(run)(run)滑(hua)油，先把(ba)靜(jing)環(huan)(huan)輕輕定位裝(zhuang)入導(dao)軸承座(zuo)(zuo)，再在泵軸上(shang)(shang)抹上(shang)(shang)潤(run)(run)滑(hua)油，把(ba)動(dong)環(huan)(huan)部(bu)(bu)分輕輕裝(zhuang)入泵軸上(shang)(shang)，用(yong)手輕推密封環(huan)(huan)應能伸縮(suo)自(zi)如，注意動(dong)、靜(jing)環(huan)(huan)部(bu)(bu)分的防轉部(bu)(bu)位需裝(zhuang)配到(dao)位。

　　裝(zhuang)聯(lian)(lian)軸(zhou)器(qi)(qi)：在電(dian)機軸(zhou)頭上裝(zhuang)上擋(dang)圈，裝(zhuang)上一(yi)半聯(lian)(lian)軸(zhou)器(qi)(qi)，再在泵軸(zhou)端和聯(lian)(lian)軸(zhou)器(qi)(qi)槽內裝(zhuang)上擋(dang)塊并用梅花扳手擰(ning)緊螺栓；再裝(zhuang)上另一(yi)半聯(lian)(lian)軸(zhou)器(qi)(qi)擰(ning)上內六角螺釘。安裝(zhuang)聯(lian)(lian)軸(zhou)器(qi)(qi)正(zheng)確的(de)檢查要求：對(dui)分(fen)式聯(lian)(lian)軸(zhou)器(qi)(qi)上下間隙(xi)需要均勻，用手盤(pan)動(dong)(dong)聯(lian)(lian)軸(zhou)器(qi)(qi)幾圈檢查轉(zhuan)動(dong)(dong)的(de)靈活性。

　　裝(zhuang)密(mi)封(feng)座：先(xian)將密(mi)封(feng)座裝(zhuang)入橡膠油封(feng)，再把密(mi)封(feng)座裝(zhuang)入泵蓋(gai)并壓(ya)(ya)在軸(zhou)承座上(shang)，擰(ning)緊螺(luo)母(mu)，確(que)保所有安(an)(an)裝(zhuang)螺(luo)釘(ding)緊固(gu)。當安(an)(an)裝(zhuang)螺(luo)釘(ding)被用作密(mi)封(feng)與軸(zhou)之間的驅動時(shi)(shi)(shi)，軸(zhou)應(ying)(ying)打埋頭孔來加固(gu)連接(jie)，緊固(gu)壓(ya)(ya)蓋(gai)螺(luo)栓(shuan)時(shi)(shi)(shi)應(ying)(ying)該平穩(wen)緊固(gu)，并且(qie)不(bu)要(yao)使(shi)壓(ya)(ya)蓋(gai)受彈力。在可(ke)能(neng)的地方使(shi)用4個以上(shang)螺(luo)釘(ding)的等(deng)間距壓(ya)(ya)蓋(gai)，緊固(gu)壓(ya)(ya)蓋(gai)螺(luo)栓(shuan)時(shi)(shi)(shi)，用塞尺檢查軸(zhou)與壓(ya)(ya)蓋(gai)之間的間隙，這在密(mi)封(feng)腔對(dui)壓(ya)(ya)蓋(gai)不(bu)導向時(shi)(shi)(shi)，顯得特別重要(yao)，因為壓(ya)(ya)蓋(gai)必須對(dui)中(zhong)。
