建華機械密封利用(yong)機(ji)(ji)械(xie)方式(shi)傳(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)(dong)力和(he)(he)運動(dong)(dong)(dong)(dong)(dong)(dong)的(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)，機(ji)(ji)械(xie)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)在機(ji)(ji)械(xie)工程中應(ying)(ying)用(yong)非常廣泛，有多種形式(shi)，主要包(bao)括皮帶傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、齒(chi)(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(gan)蝸輪傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、齒(chi)(chi)輪齒(chi)(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)(chi)輪傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)能夠用(yong)于(yu)大功率的(de)場(chang)合，傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比準確，但(dan)一(yi)般要求較高的(de)制造精(jing)度(du)和(he)(he)安裝精(jing)度(du)。還(huan)有一(yi)類是(shi)靠機(ji)(ji)件間的(de)摩擦力傳(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)(dong)力和(he)(he)運動(dong)(dong)(dong)(dong)(dong)(dong)的(de)摩擦傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)，包(bao)括帶傳(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)(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(wu)級變速，可以(yi)適應(ying)(ying)軸(zhou)間距較大的(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)場(chang)合，而過(guo)載打滑還(huan)能起到(dao)緩沖(chong)和(he)(he)保(bao)護傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)裝置(zhi)的(de)作用(yong)，但(dan)這種傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)一(yi)般不(bu)能用(yong)于(yu)大功率的(de)場(chang)合，也(ye)不(bu)能保(bao)證(zheng)準確的(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比。

　　傳動形式多，但是建華機械密封的更換工作(zuo)大同小異，首先拆前(qian)需確認電(dian)機處于檢(jian)修(xiu)狀態，擰下加油螺塞，用吸管把密封座(zuo)腔(qiang)內的潤滑油吸出(chu)。準備(bei)好放置泵零件的工作(zuo)臺及(ji)拆裝工具，切勿任意(yi)亂放亂用，避(bi)免碰壞泵的零部(bu)件。

　　拆對分式聯(lian)(lian)軸器(qi)：先把聯(lian)(lian)軸器(qi)的固(gu)定內六角螺(luo)釘擰(ning)下來，再輕輕把聯(lian)(lian)軸器(qi)的一(yi)半從軸上慢(man)慢(man)拉下，注(zhu)意不要(yao)掉了，再用梅(mei)花扳(ban)手擰(ning)下泵(beng)軸吊緊螺(luo)栓(shuan)和(he)擋(dang)塊，讓葉(xie)輪慢(man)慢(man)下沉至泵(beng)體(ti)，然后拆下另(ling)外(wai)一(yi)半聯(lian)(lian)軸器(qi)，拿下泵(beng)軸擋(dang)圈(quan)。

　　拆卸建華機械密封：抓住密(mi)封(feng)彈簧順(shun)著泵軸往上(shang)提，就(jiu)能(neng)拆下來(lai)了。

　　拆卸(xie)并(bing)清洗(xi)(xi)軸(zhou)(zhou)承(cheng)座：先輕(qing)輕(qing)松動一下軸(zhou)(zhou)承(cheng)座后用拆卸(xie)螺(luo)栓頂起軸(zhou)(zhou)承(cheng)座，并(bing)且沿(yan)著泵軸(zhou)(zhou)往上提而卸(xie)下，再用噴氣燃料清洗(xi)(xi)軸(zhou)(zhou)承(cheng)及座，裝前晾(liang)干并(bing)涂抹少許20號機械油用來潤滑保(bao)護。

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

　　建華機械密封裝配：在(zai)(zai)動、靜環(huan)鏡面上(shang)涂一層潔凈的(de)20號(hao)潤(run)滑(hua)(hua)油(you)，導軸(zhou)(zhou)承(cheng)座(zuo)也抹上(shang)潤(run)滑(hua)(hua)油(you)，先把靜環(huan)輕輕定位裝入導軸(zhou)(zhou)承(cheng)座(zuo)，再在(zai)(zai)泵軸(zhou)(zhou)上(shang)抹上(shang)潤(run)滑(hua)(hua)油(you)，把動環(huan)部分(fen)輕輕裝入泵軸(zhou)(zhou)上(shang)，用手輕推密封環(huan)應能(neng)伸縮自如(ru)，注意動、靜環(huan)部分(fen)的(de)防轉部位需裝配到位。

　　裝(zhuang)(zhuang)聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)：在電(dian)機軸(zhou)(zhou)頭上(shang)裝(zhuang)(zhuang)上(shang)擋圈，裝(zhuang)(zhuang)上(shang)一(yi)半聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)，再在泵軸(zhou)(zhou)端和聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)槽內裝(zhuang)(zhuang)上(shang)擋塊并用(yong)梅花扳手擰緊(jin)螺栓；再裝(zhuang)(zhuang)上(shang)另一(yi)半聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)擰上(shang)內六角(jiao)螺釘。安裝(zhuang)(zhuang)聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)正確的檢查(cha)要(yao)求：對分(fen)式聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)上(shang)下間隙需要(yao)均勻，用(yong)手盤動聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)幾圈檢查(cha)轉(zhuan)動的靈活性(xing)。

　　裝(zhuang)密封(feng)座(zuo)：先將(jiang)密封(feng)座(zuo)裝(zhuang)入橡膠(jiao)油封(feng)，再把密封(feng)座(zuo)裝(zhuang)入泵蓋(gai)并壓(ya)在軸(zhou)(zhou)(zhou)承座(zuo)上，擰緊螺母，確保所有安(an)(an)裝(zhuang)螺釘(ding)緊固(gu)。當安(an)(an)裝(zhuang)螺釘(ding)被用(yong)作密封(feng)與軸(zhou)(zhou)(zhou)之間的驅動時(shi)，軸(zhou)(zhou)(zhou)應(ying)打埋頭孔來(lai)加固(gu)連接，緊固(gu)壓(ya)蓋(gai)螺栓時(shi)應(ying)該(gai)平(ping)穩緊固(gu)，并且不(bu)要(yao)使壓(ya)蓋(gai)受彈(dan)力。在可能的地方(fang)使用(yong)4個以上螺釘(ding)的等間距壓(ya)蓋(gai)，緊固(gu)壓(ya)蓋(gai)螺栓時(shi)，用(yong)塞尺檢(jian)查軸(zhou)(zhou)(zhou)與壓(ya)蓋(gai)之間的間隙(xi)，這在密封(feng)腔(qiang)對壓(ya)蓋(gai)不(bu)導向時(shi)，顯得特別重要(yao)，因為(wei)壓(ya)蓋(gai)必須對中(zhong)。
