汶川機械密封利用機(ji)(ji)械方式傳(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)力和(he)(he)運(yun)動(dong)(dong)(dong)(dong)(dong)的傳(chuan)動(dong)(dong)(dong)(dong)(dong)，機(ji)(ji)械傳(chuan)動(dong)(dong)(dong)(dong)(dong)在(zai)機(ji)(ji)械工程中應用非常廣泛(fan)，有(you)多種形式，主要包(bao)括(kuo)(kuo)皮帶(dai)傳(chuan)動(dong)(dong)(dong)(dong)(dong)、齒輪傳(chuan)動(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)動(dong)(dong)(dong)(dong)(dong)、蝸(gua)桿蝸(gua)輪傳(chuan)動(dong)(dong)(dong)(dong)(dong)、齒輪齒條傳(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)(he)螺旋傳(chuan)動(dong)(dong)(dong)(dong)(dong)等。齒輪傳(chuan)動(dong)(dong)(dong)(dong)(dong)能夠(gou)用于大(da)(da)功(gong)率的場(chang)(chang)合(he)，傳(chuan)動(dong)(dong)(dong)(dong)(dong)比(bi)準確，但(dan)一(yi)(yi)般要求較高的制造精度和(he)(he)安裝精度。還有(you)一(yi)(yi)類是(shi)靠(kao)機(ji)(ji)件間的摩(mo)擦力傳(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)力和(he)(he)運(yun)動(dong)(dong)(dong)(dong)(dong)的摩(mo)擦傳(chuan)動(dong)(dong)(dong)(dong)(dong)，包(bao)括(kuo)(kuo)帶(dai)傳(chuan)動(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)(he)摩(mo)擦輪傳(chuan)動(dong)(dong)(dong)(dong)(dong)等。摩(mo)擦傳(chuan)動(dong)(dong)(dong)(dong)(dong)容(rong)易實現無級變速，可以(yi)適應軸間距較大(da)(da)的傳(chuan)動(dong)(dong)(dong)(dong)(dong)場(chang)(chang)合(he)，而過載打滑還能起到緩沖和(he)(he)保護傳(chuan)動(dong)(dong)(dong)(dong)(dong)裝置的作用，但(dan)這種傳(chuan)動(dong)(dong)(dong)(dong)(dong)一(yi)(yi)般不能用于大(da)(da)功(gong)率的場(chang)(chang)合(he)，也不能保證(zheng)準確的傳(chuan)動(dong)(dong)(dong)(dong)(dong)比(bi)。

　　傳動形式多，但是汶川機械密封的更換工作大同(tong)小異(yi)，首(shou)先(xian)拆(chai)前需確認電機處(chu)于檢修狀(zhuang)態，擰下加油(you)螺塞，用吸管(guan)把密封座腔內的潤滑(hua)油(you)吸出。準備好(hao)放置(zhi)泵零(ling)(ling)件(jian)(jian)的工作臺及拆(chai)裝工具，切(qie)勿任意亂放亂用，避免(mian)碰壞泵的零(ling)(ling)部件(jian)(jian)。

　　拆對分式聯(lian)(lian)(lian)軸(zhou)器：先把(ba)聯(lian)(lian)(lian)軸(zhou)器的(de)固定內六(liu)角螺釘擰下(xia)(xia)(xia)來，再輕輕把(ba)聯(lian)(lian)(lian)軸(zhou)器的(de)一半(ban)從軸(zhou)上慢(man)(man)慢(man)(man)拉下(xia)(xia)(xia)，注意不要掉了，再用梅花扳手擰下(xia)(xia)(xia)泵軸(zhou)吊緊螺栓和(he)擋(dang)塊(kuai)，讓葉輪(lun)慢(man)(man)慢(man)(man)下(xia)(xia)(xia)沉(chen)至泵體，然(ran)后(hou)拆下(xia)(xia)(xia)另(ling)外一半(ban)聯(lian)(lian)(lian)軸(zhou)器，拿下(xia)(xia)(xia)泵軸(zhou)擋(dang)圈。

　　拆卸汶川機械密封：抓住(zhu)密封彈簧順著泵軸往(wang)上(shang)提，就(jiu)能拆下來了。

　　拆(chai)卸(xie)(xie)并(bing)清(qing)洗軸(zhou)(zhou)承(cheng)座(zuo)：先輕輕松動一下軸(zhou)(zhou)承(cheng)座(zuo)后用(yong)拆(chai)卸(xie)(xie)螺(luo)栓頂起軸(zhou)(zhou)承(cheng)座(zuo)，并(bing)且沿著泵軸(zhou)(zhou)往(wang)上提而(er)卸(xie)(xie)下，再用(yong)噴氣(qi)燃料(liao)清(qing)洗軸(zhou)(zhou)承(cheng)及座(zuo)，裝前晾干并(bing)涂抹少許20號機(ji)械油用(yong)來潤滑保護。

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

　　汶川機械密封裝(zhuang)(zhuang)配：在(zai)動、靜環(huan)(huan)鏡面(mian)上(shang)(shang)涂一(yi)層潔凈的(de)(de)20號潤滑(hua)油(you)，導軸(zhou)(zhou)承(cheng)座也抹上(shang)(shang)潤滑(hua)油(you)，先把靜環(huan)(huan)輕輕定位裝(zhuang)(zhuang)入導軸(zhou)(zhou)承(cheng)座，再(zai)在(zai)泵軸(zhou)(zhou)上(shang)(shang)抹上(shang)(shang)潤滑(hua)油(you)，把動環(huan)(huan)部分(fen)輕輕裝(zhuang)(zhuang)入泵軸(zhou)(zhou)上(shang)(shang)，用手輕推密封(feng)環(huan)(huan)應能伸縮自(zi)如，注意動、靜環(huan)(huan)部分(fen)的(de)(de)防(fang)轉部位需裝(zhuang)(zhuang)配到位。

　　裝(zhuang)聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)：在(zai)電機軸(zhou)(zhou)(zhou)頭上(shang)(shang)裝(zhuang)上(shang)(shang)擋(dang)圈(quan)，裝(zhuang)上(shang)(shang)一(yi)半聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)，再(zai)在(zai)泵軸(zhou)(zhou)(zhou)端和聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)槽內(nei)裝(zhuang)上(shang)(shang)擋(dang)塊并用梅花扳手(shou)擰緊螺栓；再(zai)裝(zhuang)上(shang)(shang)另(ling)一(yi)半聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)擰上(shang)(shang)內(nei)六角螺釘(ding)。安(an)裝(zhuang)聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)正確(que)的檢(jian)查要(yao)求：對分式聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)上(shang)(shang)下間隙需(xu)要(yao)均勻，用手(shou)盤(pan)動(dong)(dong)聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)幾圈(quan)檢(jian)查轉動(dong)(dong)的靈活性。

　　裝(zhuang)密封(feng)座：先將密封(feng)座裝(zhuang)入(ru)橡(xiang)膠油封(feng)，再把(ba)密封(feng)座裝(zhuang)入(ru)泵蓋(gai)(gai)并壓(ya)(ya)(ya)在軸承座上，擰緊(jin)(jin)螺(luo)母(mu)，確保所(suo)有(you)安(an)(an)裝(zhuang)螺(luo)釘(ding)緊(jin)(jin)固。當安(an)(an)裝(zhuang)螺(luo)釘(ding)被用作密封(feng)與(yu)軸之間的(de)(de)驅動時，軸應打埋頭(tou)孔來加固連接，緊(jin)(jin)固壓(ya)(ya)(ya)蓋(gai)(gai)螺(luo)栓時應該平穩緊(jin)(jin)固，并且不要使(shi)壓(ya)(ya)(ya)蓋(gai)(gai)受彈力。在可能的(de)(de)地(di)方(fang)使(shi)用4個以上螺(luo)釘(ding)的(de)(de)等間距(ju)壓(ya)(ya)(ya)蓋(gai)(gai)，緊(jin)(jin)固壓(ya)(ya)(ya)蓋(gai)(gai)螺(luo)栓時，用塞尺檢查軸與(yu)壓(ya)(ya)(ya)蓋(gai)(gai)之間的(de)(de)間隙，這在密封(feng)腔對(dui)壓(ya)(ya)(ya)蓋(gai)(gai)不導(dao)向時，顯得特別重(zhong)要，因為壓(ya)(ya)(ya)蓋(gai)(gai)必須對(dui)中。
