方山機械密封利用(yong)機械(xie)方式傳(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)(dong)力和(he)運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)的(de)(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(zai)機械(xie)工程中(zhong)應(ying)用(yong)非常(chang)廣(guang)泛(fan)，有(you)多種形式，主要(yao)包括(kuo)皮帶傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、鏈(lian)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、蝸(gua)桿蝸(gua)輪(lun)(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)(lun)(lun)齒(chi)條(tiao)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)和(he)螺旋傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)等。齒(chi)輪(lun)(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)能(neng)夠用(yong)于大功率(lv)的(de)(de)(de)場(chang)合，傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比(bi)準(zhun)確，但一(yi)般(ban)要(yao)求較(jiao)高的(de)(de)(de)制造(zao)精度(du)和(he)安裝精度(du)。還有(you)一(yi)類是靠機件間的(de)(de)(de)摩擦(ca)力傳(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)(dong)力和(he)運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)摩擦(ca)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)，包括(kuo)帶傳(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)摩擦(ca)輪(lun)(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)等。摩擦(ca)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)容易實現無(wu)級變速，可(ke)以適(shi)應(ying)軸間距較(jiao)大的(de)(de)(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)場(chang)合，而過載(zai)打滑還能(neng)起到緩沖和(he)保護傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)裝置的(de)(de)(de)作用(yong)，但這種傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)一(yi)般(ban)不能(neng)用(yong)于大功率(lv)的(de)(de)(de)場(chang)合，也不能(neng)保證準(zhun)確的(de)(de)(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比(bi)。

　　傳動形式多，但是方山機械密封的更(geng)換工作大同小異，首(shou)先(xian)拆前需確(que)認(ren)電機處于檢修狀態，擰(ning)下加(jia)油螺塞，用吸(xi)管把(ba)密封座腔內的潤滑(hua)油吸(xi)出。準(zhun)備好放置泵(beng)零件(jian)的工作臺(tai)及拆裝工具(ju)，切勿任意亂放亂用，避免碰壞(huai)泵(beng)的零部件(jian)。

　　拆(chai)對分式聯(lian)軸(zhou)器：先把聯(lian)軸(zhou)器的(de)固定內六角(jiao)螺(luo)釘擰下(xia)來，再(zai)輕(qing)輕(qing)把聯(lian)軸(zhou)器的(de)一半從軸(zhou)上慢(man)慢(man)拉下(xia)，注意不要掉(diao)了(le)，再(zai)用(yong)梅花(hua)扳(ban)手擰下(xia)泵(beng)(beng)軸(zhou)吊緊螺(luo)栓和(he)擋(dang)(dang)塊(kuai)，讓葉輪慢(man)慢(man)下(xia)沉至泵(beng)(beng)體，然后拆(chai)下(xia)另外(wai)一半聯(lian)軸(zhou)器，拿下(xia)泵(beng)(beng)軸(zhou)擋(dang)(dang)圈。

　　拆卸方山機械密封：抓(zhua)住密封彈簧(huang)順著(zhu)泵(beng)軸往上提，就能拆下來了。

　　拆卸(xie)并(bing)(bing)清(qing)洗軸承(cheng)座(zuo)：先輕輕松動一下軸承(cheng)座(zuo)后(hou)用拆卸(xie)螺栓頂起軸承(cheng)座(zuo)，并(bing)(bing)且(qie)沿著泵軸往上提而卸(xie)下，再(zai)用噴(pen)氣燃料清(qing)洗軸承(cheng)及座(zuo)，裝前晾干并(bing)(bing)涂抹少許20號機(ji)械油用來潤滑保護。

　　拆密(mi)封座：擰(ning)下密(mi)封座壓緊(jin)螺(luo)母，輕(qing)輕(qing)卸下密(mi)封座并清洗。

　　方山機械密封裝(zhuang)配(pei)：在(zai)(zai)動、靜環鏡面上(shang)涂一層(ceng)潔凈(jing)的(de)20號潤(run)滑油，導軸(zhou)承座(zuo)也抹上(shang)潤(run)滑油，先把靜環輕(qing)輕(qing)定位裝(zhuang)入導軸(zhou)承座(zuo)，再在(zai)(zai)泵軸(zhou)上(shang)抹上(shang)潤(run)滑油，把動環部(bu)分輕(qing)輕(qing)裝(zhuang)入泵軸(zhou)上(shang)，用(yong)手輕(qing)推密封(feng)環應(ying)能伸縮(suo)自(zi)如，注意動、靜環部(bu)分的(de)防轉部(bu)位需裝(zhuang)配(pei)到(dao)位。

　　裝(zhuang)(zhuang)(zhuang)聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)：在(zai)電機(ji)軸(zhou)頭上裝(zhuang)(zhuang)(zhuang)上擋(dang)圈，裝(zhuang)(zhuang)(zhuang)上一半(ban)聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)，再(zai)在(zai)泵軸(zhou)端和聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)槽內裝(zhuang)(zhuang)(zhuang)上擋(dang)塊并用梅(mei)花扳手(shou)擰(ning)緊螺栓；再(zai)裝(zhuang)(zhuang)(zhuang)上另一半(ban)聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)擰(ning)上內六角螺釘。安裝(zhuang)(zhuang)(zhuang)聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)正確的檢查(cha)要求(qiu)：對分式聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)上下間隙需(xu)要均勻(yun)，用手(shou)盤動(dong)聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)幾圈檢查(cha)轉動(dong)的靈活性(xing)。

　　裝密(mi)(mi)封座：先將密(mi)(mi)封座裝入橡膠油封，再(zai)把密(mi)(mi)封座裝入泵蓋并壓(ya)(ya)(ya)在(zai)軸(zhou)承(cheng)座上(shang)，擰緊螺母，確保(bao)所(suo)有(you)安(an)裝螺釘緊固。當安(an)裝螺釘被(bei)用作密(mi)(mi)封與軸(zhou)之間(jian)的(de)驅(qu)動時(shi)，軸(zhou)應打(da)埋頭孔來加固連接，緊固壓(ya)(ya)(ya)蓋螺栓時(shi)應該平(ping)穩緊固，并且不要使壓(ya)(ya)(ya)蓋受彈力。在(zai)可(ke)能的(de)地方(fang)使用4個以上(shang)螺釘的(de)等間(jian)距壓(ya)(ya)(ya)蓋，緊固壓(ya)(ya)(ya)蓋螺栓時(shi)，用塞尺檢查(cha)軸(zhou)與壓(ya)(ya)(ya)蓋之間(jian)的(de)間(jian)隙，這在(zai)密(mi)(mi)封腔對壓(ya)(ya)(ya)蓋不導向時(shi)，顯得特別重要，因為(wei)壓(ya)(ya)(ya)蓋必須對中。
