長垣機械密封利用機(ji)械(xie)方式(shi)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)力和(he)(he)運動(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，機(ji)械(xie)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)在(zai)機(ji)械(xie)工程中應用非常廣泛，有(you)多種形式(shi)，主要(yao)包括皮(pi)帶(dai)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、蝸(gua)桿蝸(gua)輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)齒(chi)條傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)(he)螺旋傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等。齒(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)能(neng)夠用于(yu)大功(gong)率的(de)(de)(de)場(chang)合(he)，傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比(bi)準確，但一(yi)(yi)般要(yao)求較(jiao)高的(de)(de)(de)制造精度和(he)(he)安裝精度。還有(you)一(yi)(yi)類是(shi)靠機(ji)件間的(de)(de)(de)摩擦力傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)力和(he)(he)運動(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)摩擦傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，包括帶(dai)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)(he)摩擦輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等。摩擦傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)容易實(shi)現無級變速，可以適應軸間距較(jiao)大的(de)(de)(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)場(chang)合(he)，而(er)過載打(da)滑還能(neng)起(qi)到緩沖和(he)(he)保護(hu)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)裝置的(de)(de)(de)作用，但這種傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)一(yi)(yi)般不能(neng)用于(yu)大功(gong)率的(de)(de)(de)場(chang)合(he)，也不能(neng)保證(zheng)準確的(de)(de)(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比(bi)。

　　傳動形式多，但是長垣機械密封的更換工作大同(tong)小異(yi)，首(shou)先拆前(qian)需確(que)認(ren)電機處于檢修狀態，擰(ning)下加油(you)螺塞，用吸管把密(mi)封座腔(qiang)內的潤滑油(you)吸出。準備好放置泵(beng)零(ling)件的工作臺(tai)及拆裝工具，切勿任意亂放亂用，避免碰壞泵(beng)的零(ling)部件。

　　拆(chai)對分式聯軸(zhou)(zhou)器(qi)：先把(ba)聯軸(zhou)(zhou)器(qi)的固定內六角螺釘擰下來，再輕輕把(ba)聯軸(zhou)(zhou)器(qi)的一半從軸(zhou)(zhou)上慢(man)慢(man)拉下，注意不要(yao)掉了，再用(yong)梅花(hua)扳手(shou)擰下泵(beng)軸(zhou)(zhou)吊緊螺栓和擋塊，讓葉輪慢(man)慢(man)下沉(chen)至泵(beng)體，然(ran)后拆(chai)下另外一半聯軸(zhou)(zhou)器(qi)，拿下泵(beng)軸(zhou)(zhou)擋圈(quan)。

　　拆卸長垣機械密封：抓(zhua)住密(mi)封彈簧順著泵軸(zhou)往上提(ti)，就能拆下來了。

　　拆(chai)卸并清(qing)洗軸(zhou)承座：先輕輕松動一下軸(zhou)承座后用(yong)拆(chai)卸螺栓頂(ding)起軸(zhou)承座，并且沿(yan)著泵軸(zhou)往上提而卸下，再用(yong)噴氣(qi)燃料清(qing)洗軸(zhou)承及(ji)座，裝前晾干并涂抹少(shao)許20號機械(xie)油用(yong)來(lai)潤滑保(bao)護(hu)。

　　拆(chai)密(mi)封(feng)座：擰(ning)下(xia)密(mi)封(feng)座壓緊螺母，輕(qing)(qing)輕(qing)(qing)卸下(xia)密(mi)封(feng)座并清洗。

　　長垣機械密封裝配(pei)：在(zai)動、靜(jing)環(huan)(huan)鏡面上(shang)涂一(yi)層潔凈的20號潤滑油，導軸(zhou)承(cheng)座也抹上(shang)潤滑油，先把(ba)靜(jing)環(huan)(huan)輕(qing)輕(qing)定位裝入導軸(zhou)承(cheng)座，再在(zai)泵軸(zhou)上(shang)抹上(shang)潤滑油，把(ba)動環(huan)(huan)部(bu)分輕(qing)輕(qing)裝入泵軸(zhou)上(shang)，用(yong)手輕(qing)推密封(feng)環(huan)(huan)應能(neng)伸縮(suo)自(zi)如，注意動、靜(jing)環(huan)(huan)部(bu)分的防轉部(bu)位需裝配(pei)到位。

　　裝(zhuang)(zhuang)聯軸(zhou)器(qi)(qi)(qi)：在電機軸(zhou)頭上(shang)裝(zhuang)(zhuang)上(shang)擋圈(quan)，裝(zhuang)(zhuang)上(shang)一半(ban)聯軸(zhou)器(qi)(qi)(qi)，再在泵軸(zhou)端和聯軸(zhou)器(qi)(qi)(qi)槽(cao)內裝(zhuang)(zhuang)上(shang)擋塊并用(yong)梅花扳手(shou)擰緊螺(luo)栓；再裝(zhuang)(zhuang)上(shang)另一半(ban)聯軸(zhou)器(qi)(qi)(qi)擰上(shang)內六角(jiao)螺(luo)釘。安裝(zhuang)(zhuang)聯軸(zhou)器(qi)(qi)(qi)正(zheng)確的檢(jian)查要求：對分式聯軸(zhou)器(qi)(qi)(qi)上(shang)下(xia)間隙需要均勻，用(yong)手(shou)盤動(dong)聯軸(zhou)器(qi)(qi)(qi)幾圈(quan)檢(jian)查轉動(dong)的靈活性。

　　裝密(mi)(mi)封(feng)座：先將密(mi)(mi)封(feng)座裝入(ru)橡膠油(you)封(feng)，再把密(mi)(mi)封(feng)座裝入(ru)泵(beng)蓋并壓(ya)在(zai)(zai)軸(zhou)承座上，擰(ning)緊螺(luo)(luo)母(mu)，確保(bao)所有(you)安(an)裝螺(luo)(luo)釘(ding)緊固(gu)。當安(an)裝螺(luo)(luo)釘(ding)被用作密(mi)(mi)封(feng)與(yu)軸(zhou)之間的驅動(dong)時，軸(zhou)應打(da)埋頭孔來(lai)加固(gu)連接(jie)，緊固(gu)壓(ya)蓋螺(luo)(luo)栓時應該平穩緊固(gu)，并且不要使壓(ya)蓋受彈力(li)。在(zai)(zai)可能(neng)的地方(fang)使用4個以上螺(luo)(luo)釘(ding)的等間距壓(ya)蓋，緊固(gu)壓(ya)蓋螺(luo)(luo)栓時，用塞尺檢查軸(zhou)與(yu)壓(ya)蓋之間的間隙，這在(zai)(zai)密(mi)(mi)封(feng)腔對壓(ya)蓋不導向時，顯得(de)特別重要，因為壓(ya)蓋必須對中。
