方山機械密封利(li)用機械方(fang)式傳(chuan)(chuan)(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)力(li)和(he)(he)運(yun)動(dong)(dong)(dong)(dong)的(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)，機械傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)在機械工程中應(ying)用非(fei)常廣(guang)泛，有(you)多種(zhong)形式，主要包括(kuo)皮(pi)帶傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒輪傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、蝸桿(gan)蝸輪傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒輪齒條傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)(he)螺旋傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)等。齒輪傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)能(neng)夠用于(yu)大功率的(de)場合，傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)比準確(que)，但(dan)一般要求較高的(de)制造精度和(he)(he)安裝精度。還有(you)一類是靠機件(jian)間(jian)的(de)摩(mo)擦力(li)傳(chuan)(chuan)(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)力(li)和(he)(he)運(yun)動(dong)(dong)(dong)(dong)的(de)摩(mo)擦傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)，包括(kuo)帶傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)(he)摩(mo)擦輪傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)等。摩(mo)擦傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)容易實現無級(ji)變速，可以適應(ying)軸間(jian)距(ju)較大的(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)場合，而過載打滑還能(neng)起到緩沖和(he)(he)保護傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)裝置(zhi)的(de)作用，但(dan)這種(zhong)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)一般不能(neng)用于(yu)大功率的(de)場合，也不能(neng)保證準確(que)的(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)比。

　　傳動形式多，但是方山機械密封的(de)更換工作(zuo)大同小異，首先拆前(qian)需確認(ren)電機(ji)處于檢修狀態，擰下加(jia)油(you)螺塞(sai)，用吸管把密封(feng)座腔內的(de)潤滑油(you)吸出。準備好放置泵零件的(de)工作(zuo)臺(tai)及拆裝工具，切勿任意亂放亂用，避免碰壞泵的(de)零部件。

　　拆對分式聯(lian)軸(zhou)器：先把聯(lian)軸(zhou)器的固(gu)定內六角螺釘擰下(xia)(xia)來，再(zai)輕輕把聯(lian)軸(zhou)器的一半從軸(zhou)上慢(man)(man)慢(man)(man)拉(la)下(xia)(xia)，注意不要掉了，再(zai)用梅花扳手擰下(xia)(xia)泵(beng)軸(zhou)吊緊(jin)螺栓和擋(dang)塊，讓葉輪慢(man)(man)慢(man)(man)下(xia)(xia)沉(chen)至(zhi)泵(beng)體(ti)，然后拆下(xia)(xia)另外一半聯(lian)軸(zhou)器，拿下(xia)(xia)泵(beng)軸(zhou)擋(dang)圈。

　　拆卸方山機械密封：抓住密(mi)封(feng)彈簧順著泵(beng)軸往上(shang)提，就能拆下來(lai)了。

　　拆卸并(bing)清洗(xi)軸(zhou)(zhou)(zhou)承(cheng)(cheng)座(zuo)：先輕(qing)輕(qing)松動一下軸(zhou)(zhou)(zhou)承(cheng)(cheng)座(zuo)后用(yong)拆卸螺栓頂起軸(zhou)(zhou)(zhou)承(cheng)(cheng)座(zuo)，并(bing)且沿著泵軸(zhou)(zhou)(zhou)往上(shang)提而卸下，再用(yong)噴氣燃料(liao)清洗(xi)軸(zhou)(zhou)(zhou)承(cheng)(cheng)及座(zuo)，裝前晾干并(bing)涂抹少許20號機械油用(yong)來潤滑保護。

　　拆密(mi)(mi)封(feng)座(zuo)：擰下(xia)密(mi)(mi)封(feng)座(zuo)壓緊螺母，輕(qing)輕(qing)卸下(xia)密(mi)(mi)封(feng)座(zuo)并清洗。

　　方山機械密封裝(zhuang)配：在動(dong)(dong)、靜(jing)環鏡面上(shang)涂一層(ceng)潔凈的20號潤(run)滑油(you)，導(dao)軸承(cheng)(cheng)座也抹上(shang)潤(run)滑油(you)，先(xian)把(ba)靜(jing)環輕(qing)輕(qing)定位裝(zhuang)入(ru)導(dao)軸承(cheng)(cheng)座，再(zai)在泵軸上(shang)抹上(shang)潤(run)滑油(you)，把(ba)動(dong)(dong)環部(bu)分輕(qing)輕(qing)裝(zhuang)入(ru)泵軸上(shang)，用手輕(qing)推(tui)密封環應能伸縮自(zi)如(ru)，注意動(dong)(dong)、靜(jing)環部(bu)分的防轉部(bu)位需裝(zhuang)配到位。

　　裝(zhuang)(zhuang)(zhuang)聯(lian)軸(zhou)(zhou)(zhou)器(qi)：在電機(ji)軸(zhou)(zhou)(zhou)頭(tou)上裝(zhuang)(zhuang)(zhuang)上擋圈，裝(zhuang)(zhuang)(zhuang)上一(yi)半聯(lian)軸(zhou)(zhou)(zhou)器(qi)，再在泵軸(zhou)(zhou)(zhou)端和聯(lian)軸(zhou)(zhou)(zhou)器(qi)槽(cao)內(nei)(nei)裝(zhuang)(zhuang)(zhuang)上擋塊并用梅花扳手(shou)擰(ning)緊螺栓；再裝(zhuang)(zhuang)(zhuang)上另一(yi)半聯(lian)軸(zhou)(zhou)(zhou)器(qi)擰(ning)上內(nei)(nei)六角螺釘。安裝(zhuang)(zhuang)(zhuang)聯(lian)軸(zhou)(zhou)(zhou)器(qi)正確的檢查要(yao)求(qiu)：對分式聯(lian)軸(zhou)(zhou)(zhou)器(qi)上下間隙需要(yao)均勻，用手(shou)盤動聯(lian)軸(zhou)(zhou)(zhou)器(qi)幾圈檢查轉動的靈活(huo)性。

　　裝(zhuang)(zhuang)密封(feng)座(zuo)(zuo)(zuo)：先將密封(feng)座(zuo)(zuo)(zuo)裝(zhuang)(zhuang)入橡膠油(you)封(feng)，再把(ba)密封(feng)座(zuo)(zuo)(zuo)裝(zhuang)(zhuang)入泵蓋并壓(ya)(ya)在軸承座(zuo)(zuo)(zuo)上，擰緊螺(luo)母，確(que)保所(suo)有(you)安(an)裝(zhuang)(zhuang)螺(luo)釘(ding)緊固(gu)。當(dang)安(an)裝(zhuang)(zhuang)螺(luo)釘(ding)被(bei)用(yong)作(zuo)密封(feng)與軸之間(jian)(jian)的驅動時(shi)，軸應打埋頭孔(kong)來(lai)加固(gu)連(lian)接(jie)，緊固(gu)壓(ya)(ya)蓋螺(luo)栓時(shi)應該平穩緊固(gu)，并且不(bu)要(yao)使(shi)壓(ya)(ya)蓋受彈力。在可能的地方使(shi)用(yong)4個(ge)以上螺(luo)釘(ding)的等間(jian)(jian)距壓(ya)(ya)蓋，緊固(gu)壓(ya)(ya)蓋螺(luo)栓時(shi)，用(yong)塞尺(chi)檢(jian)查軸與壓(ya)(ya)蓋之間(jian)(jian)的間(jian)(jian)隙，這在密封(feng)腔對(dui)壓(ya)(ya)蓋不(bu)導向(xiang)時(shi)，顯得(de)特別重要(yao)，因為壓(ya)(ya)蓋必須對(dui)中。
