西充機械密封利用(yong)機械(xie)方式傳(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)力(li)和(he)(he)運(yun)動(dong)(dong)(dong)(dong)(dong)的(de)(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，機械(xie)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)在機械(xie)工程中應用(yong)非常廣泛，有多(duo)種(zhong)形式，主要(yao)包括(kuo)皮帶傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、鏈(lian)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、蝸桿蝸輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)(chi)輪(lun)齒(chi)(chi)條(tiao)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)(he)螺旋傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等。齒(chi)(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)能(neng)夠用(yong)于大(da)功率(lv)的(de)(de)場(chang)合，傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比準確，但一般要(yao)求較高的(de)(de)制造精度和(he)(he)安裝精度。還有一類是靠機件間(jian)的(de)(de)摩(mo)擦(ca)力(li)傳(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)力(li)和(he)(he)運(yun)動(dong)(dong)(dong)(dong)(dong)的(de)(de)摩(mo)擦(ca)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，包括(kuo)帶傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)(he)摩(mo)擦(ca)輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等。摩(mo)擦(ca)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)容(rong)易實現(xian)無級變速，可以適應軸間(jian)距較大(da)的(de)(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)場(chang)合，而(er)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)(dong)裝置的(de)(de)作用(yong)，但這種(zhong)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)一般不能(neng)用(yong)于大(da)功率(lv)的(de)(de)場(chang)合，也不能(neng)保證準確的(de)(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比。

　　傳動形式多，但是西充機械密封的(de)更換工(gong)(gong)作大同(tong)小異，首先拆前需確認電機(ji)處于(yu)檢(jian)修(xiu)狀態，擰下(xia)加油(you)螺(luo)塞(sai)，用(yong)吸(xi)管把(ba)密封(feng)座腔(qiang)內的(de)潤滑(hua)油(you)吸(xi)出。準備好放(fang)置泵零(ling)件(jian)的(de)工(gong)(gong)作臺(tai)及拆裝(zhuang)工(gong)(gong)具，切勿任(ren)意亂放(fang)亂用(yong)，避免(mian)碰壞(huai)泵的(de)零(ling)部件(jian)。

　　拆(chai)對(dui)分式聯(lian)軸(zhou)器(qi)：先把聯(lian)軸(zhou)器(qi)的(de)固(gu)定內六角(jiao)螺釘(ding)擰下來，再(zai)輕輕把聯(lian)軸(zhou)器(qi)的(de)一(yi)半從軸(zhou)上(shang)慢(man)慢(man)拉下，注意(yi)不(bu)要掉了，再(zai)用梅(mei)花扳手擰下泵軸(zhou)吊緊螺栓和擋塊，讓葉輪慢(man)慢(man)下沉至泵體，然后拆(chai)下另(ling)外一(yi)半聯(lian)軸(zhou)器(qi)，拿下泵軸(zhou)擋圈。

　　拆卸西充機械密封：抓住密封彈簧順著泵軸往上提(ti)，就能拆下來了(le)。

　　拆(chai)卸并(bing)(bing)清(qing)洗(xi)軸(zhou)(zhou)(zhou)承(cheng)座(zuo)：先輕(qing)輕(qing)松動一下軸(zhou)(zhou)(zhou)承(cheng)座(zuo)后用拆(chai)卸螺栓(shuan)頂(ding)起軸(zhou)(zhou)(zhou)承(cheng)座(zuo)，并(bing)(bing)且沿(yan)著泵(beng)軸(zhou)(zhou)(zhou)往上(shang)提而卸下，再(zai)用噴氣燃料(liao)清(qing)洗(xi)軸(zhou)(zhou)(zhou)承(cheng)及座(zuo)，裝(zhuang)前(qian)晾干并(bing)(bing)涂抹(mo)少許20號機械(xie)油用來潤滑保護(hu)。

　　拆密封(feng)座(zuo)(zuo)：擰下密封(feng)座(zuo)(zuo)壓緊螺母，輕輕卸(xie)下密封(feng)座(zuo)(zuo)并清(qing)洗(xi)。

　　西充機械密封裝(zhuang)(zhuang)配(pei)：在(zai)動、靜(jing)(jing)環(huan)(huan)鏡面上(shang)涂一層潔凈的20號潤(run)滑油，導(dao)軸(zhou)承(cheng)座(zuo)也抹上(shang)潤(run)滑油，先把靜(jing)(jing)環(huan)(huan)輕輕定位裝(zhuang)(zhuang)入導(dao)軸(zhou)承(cheng)座(zuo)，再在(zai)泵軸(zhou)上(shang)抹上(shang)潤(run)滑油，把動環(huan)(huan)部分輕輕裝(zhuang)(zhuang)入泵軸(zhou)上(shang)，用手輕推(tui)密(mi)封環(huan)(huan)應能伸縮自(zi)如，注意動、靜(jing)(jing)環(huan)(huan)部分的防轉部位需裝(zhuang)(zhuang)配(pei)到(dao)位。

　　裝(zhuang)(zhuang)聯(lian)軸(zhou)(zhou)器(qi)：在電機軸(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)器(qi)，再在泵(beng)軸(zhou)(zhou)端和聯(lian)軸(zhou)(zhou)器(qi)槽內裝(zhuang)(zhuang)上(shang)擋(dang)塊并用梅花扳手(shou)擰緊螺栓；再裝(zhuang)(zhuang)上(shang)另(ling)一半聯(lian)軸(zhou)(zhou)器(qi)擰上(shang)內六角螺釘(ding)。安裝(zhuang)(zhuang)聯(lian)軸(zhou)(zhou)器(qi)正確的(de)(de)檢查要求：對(dui)分式聯(lian)軸(zhou)(zhou)器(qi)上(shang)下間(jian)隙(xi)需(xu)要均(jun)勻，用手(shou)盤(pan)動(dong)聯(lian)軸(zhou)(zhou)器(qi)幾(ji)圈檢查轉(zhuan)動(dong)的(de)(de)靈活性。

　　裝(zhuang)(zhuang)密封(feng)座：先將密封(feng)座裝(zhuang)(zhuang)入橡膠油(you)封(feng)，再把(ba)密封(feng)座裝(zhuang)(zhuang)入泵蓋(gai)(gai)(gai)(gai)并壓(ya)(ya)在軸(zhou)(zhou)承(cheng)座上(shang)，擰緊(jin)(jin)螺(luo)母，確保(bao)所有安(an)裝(zhuang)(zhuang)螺(luo)釘(ding)緊(jin)(jin)固(gu)。當安(an)裝(zhuang)(zhuang)螺(luo)釘(ding)被用(yong)作密封(feng)與軸(zhou)(zhou)之(zhi)間的驅動(dong)時，軸(zhou)(zhou)應(ying)打埋頭(tou)孔來(lai)加固(gu)連接，緊(jin)(jin)固(gu)壓(ya)(ya)蓋(gai)(gai)(gai)(gai)螺(luo)栓(shuan)時應(ying)該平穩緊(jin)(jin)固(gu)，并且不(bu)要(yao)使壓(ya)(ya)蓋(gai)(gai)(gai)(gai)受彈力。在可能(neng)的地方使用(yong)4個以上(shang)螺(luo)釘(ding)的等間距壓(ya)(ya)蓋(gai)(gai)(gai)(gai)，緊(jin)(jin)固(gu)壓(ya)(ya)蓋(gai)(gai)(gai)(gai)螺(luo)栓(shuan)時，用(yong)塞尺檢查軸(zhou)(zhou)與壓(ya)(ya)蓋(gai)(gai)(gai)(gai)之(zhi)間的間隙，這在密封(feng)腔對壓(ya)(ya)蓋(gai)(gai)(gai)(gai)不(bu)導向時，顯得特別重要(yao)，因為壓(ya)(ya)蓋(gai)(gai)(gai)(gai)必須對中。
