青羊機械密封利用(yong)機(ji)械(xie)(xie)方式(shi)傳(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)力和(he)(he)(he)運(yun)動(dong)(dong)(dong)(dong)(dong)的(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，機(ji)械(xie)(xie)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)在機(ji)械(xie)(xie)工程中(zhong)應(ying)用(yong)非常廣泛，有多種(zhong)形式(shi)，主要(yao)包(bao)括皮帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、鏈(lian)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、蝸(gua)桿蝸(gua)輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)齒(chi)條傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)(he)(he)螺旋傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等。齒(chi)輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)能夠用(yong)于大功(gong)率的(de)(de)場(chang)合(he)，傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比準確(que)，但(dan)一般要(yao)求較(jiao)(jiao)高的(de)(de)制造精度和(he)(he)(he)安(an)裝精度。還有一類是靠機(ji)件間的(de)(de)摩擦(ca)(ca)(ca)力傳(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)力和(he)(he)(he)運(yun)動(dong)(dong)(dong)(dong)(dong)的(de)(de)摩擦(ca)(ca)(ca)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，包(bao)括帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)(he)(he)摩擦(ca)(ca)(ca)輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等。摩擦(ca)(ca)(ca)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)容易實現無級(ji)變速，可(ke)以適應(ying)軸間距較(jiao)(jiao)大的(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)場(chang)合(he)，而過載打(da)滑(hua)還能起(qi)到緩沖(chong)和(he)(he)(he)保護傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)裝置的(de)(de)作用(yong)，但(dan)這種(zhong)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)一般不(bu)能用(yong)于大功(gong)率的(de)(de)場(chang)合(he)，也(ye)不(bu)能保證準確(que)的(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比。

　　傳動形式多，但是青羊機械密封的(de)更換(huan)工作大同小異，首先拆(chai)前需(xu)確(que)認(ren)電機(ji)處(chu)于檢修狀態，擰下加油(you)螺(luo)塞，用吸管把密封座(zuo)腔內(nei)的(de)潤滑油(you)吸出。準備(bei)好放置泵零件(jian)的(de)工作臺及拆(chai)裝(zhuang)工具，切勿任意亂放亂用，避免碰壞泵的(de)零部(bu)件(jian)。

　　拆(chai)對分(fen)式聯(lian)軸(zhou)(zhou)器(qi)：先把(ba)聯(lian)軸(zhou)(zhou)器(qi)的固定(ding)內六角螺釘擰(ning)下來，再(zai)輕輕把(ba)聯(lian)軸(zhou)(zhou)器(qi)的一(yi)半從(cong)軸(zhou)(zhou)上慢慢拉(la)下，注意(yi)不要掉了(le)，再(zai)用(yong)梅花扳手擰(ning)下泵(beng)軸(zhou)(zhou)吊緊(jin)螺栓和擋(dang)塊，讓葉(xie)輪慢慢下沉至泵(beng)體，然后(hou)拆(chai)下另外一(yi)半聯(lian)軸(zhou)(zhou)器(qi)，拿下泵(beng)軸(zhou)(zhou)擋(dang)圈(quan)。

　　拆卸青羊機械密封：抓住密封彈簧順著泵軸往(wang)上提(ti)，就能拆下來了。

　　拆(chai)卸并(bing)(bing)(bing)清洗軸承(cheng)座(zuo)：先(xian)輕(qing)輕(qing)松動一下軸承(cheng)座(zuo)后用(yong)拆(chai)卸螺栓頂起軸承(cheng)座(zuo)，并(bing)(bing)(bing)且沿著(zhu)泵軸往上提而(er)卸下，再用(yong)噴氣燃(ran)料清洗軸承(cheng)及(ji)座(zuo)，裝前晾干并(bing)(bing)(bing)涂(tu)抹少(shao)許20號機(ji)械(xie)油用(yong)來潤滑保護。

　　拆密封座：擰下密封座壓緊螺母，輕輕卸下密封座并清洗。

　　青羊機械密封裝配：在動、靜(jing)環(huan)鏡面上涂一層潔凈的(de)(de)20號潤滑(hua)油(you)，導軸承(cheng)座也抹上潤滑(hua)油(you)，先把(ba)靜(jing)環(huan)輕輕定位裝入導軸承(cheng)座，再在泵(beng)軸上抹上潤滑(hua)油(you)，把(ba)動環(huan)部分(fen)輕輕裝入泵(beng)軸上，用手輕推密封環(huan)應能伸縮(suo)自如(ru)，注意動、靜(jing)環(huan)部分(fen)的(de)(de)防(fang)轉部位需(xu)裝配到(dao)位。

　　裝(zhuang)(zhuang)聯(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)(qi)：在電(dian)機(ji)軸(zhou)(zhou)(zhou)(zhou)(zhou)頭上(shang)裝(zhuang)(zhuang)上(shang)擋(dang)圈，裝(zhuang)(zhuang)上(shang)一半聯(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)(qi)，再在泵軸(zhou)(zhou)(zhou)(zhou)(zhou)端和聯(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)(qi)槽內裝(zhuang)(zhuang)上(shang)擋(dang)塊(kuai)并用(yong)梅(mei)花扳手擰(ning)緊螺(luo)栓；再裝(zhuang)(zhuang)上(shang)另一半聯(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)(qi)擰(ning)上(shang)內六角螺(luo)釘。安裝(zhuang)(zhuang)聯(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)(qi)正(zheng)確的檢查要(yao)求(qiu)：對分式(shi)聯(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)(qi)上(shang)下間隙需要(yao)均勻(yun)，用(yong)手盤動聯(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)(qi)幾(ji)圈檢查轉動的靈活性。

　　裝(zhuang)(zhuang)密封座(zuo)(zuo)(zuo)：先將(jiang)密封座(zuo)(zuo)(zuo)裝(zhuang)(zhuang)入(ru)(ru)橡膠油封，再把密封座(zuo)(zuo)(zuo)裝(zhuang)(zhuang)入(ru)(ru)泵蓋(gai)(gai)并(bing)壓(ya)(ya)在軸承座(zuo)(zuo)(zuo)上(shang)，擰緊螺(luo)(luo)母，確保所有安裝(zhuang)(zhuang)螺(luo)(luo)釘緊固(gu)。當安裝(zhuang)(zhuang)螺(luo)(luo)釘被用作密封與(yu)軸之(zhi)間(jian)的驅動(dong)時，軸應打埋頭孔(kong)來加固(gu)連接，緊固(gu)壓(ya)(ya)蓋(gai)(gai)螺(luo)(luo)栓時應該平穩(wen)緊固(gu)，并(bing)且不(bu)要使(shi)壓(ya)(ya)蓋(gai)(gai)受彈力。在可能的地方使(shi)用4個以(yi)上(shang)螺(luo)(luo)釘的等間(jian)距壓(ya)(ya)蓋(gai)(gai)，緊固(gu)壓(ya)(ya)蓋(gai)(gai)螺(luo)(luo)栓時，用塞(sai)尺檢查軸與(yu)壓(ya)(ya)蓋(gai)(gai)之(zhi)間(jian)的間(jian)隙，這在密封腔對(dui)壓(ya)(ya)蓋(gai)(gai)不(bu)導向時，顯得特別重要，因(yin)為壓(ya)(ya)蓋(gai)(gai)必須(xu)對(dui)中。
