延川機械密封利用(yong)機(ji)械(xie)方式(shi)傳(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)(dong)力和(he)運動(dong)(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)，機(ji)械(xie)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)在機(ji)械(xie)工程(cheng)中(zhong)應用(yong)非常廣泛，有多種(zhong)形式(shi)，主(zhu)要包(bao)括(kuo)皮帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、蝸桿蝸輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)齒(chi)條(tiao)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)和(he)螺旋傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)等(deng)。齒(chi)輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)能(neng)夠用(yong)于(yu)大功(gong)(gong)率的(de)(de)(de)場(chang)(chang)合(he)，傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比(bi)準確，但(dan)一般要求較高的(de)(de)(de)制造精(jing)度和(he)安裝精(jing)度。還有一類是(shi)靠機(ji)件(jian)間的(de)(de)(de)摩擦力傳(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)(dong)力和(he)運動(dong)(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)摩擦傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)，包(bao)括(kuo)帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、繩(sheng)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)和(he)摩擦輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)等(deng)。摩擦傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)容易實現無級變速，可以(yi)適應軸(zhou)間距較大的(de)(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)場(chang)(chang)合(he)，而過載打(da)滑還能(neng)起到緩沖和(he)保護傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)裝置的(de)(de)(de)作用(yong)，但(dan)這種(zhong)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)一般不能(neng)用(yong)于(yu)大功(gong)(gong)率的(de)(de)(de)場(chang)(chang)合(he)，也不能(neng)保證準確的(de)(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比(bi)。

　　傳動形式多，但是延川機械密封的更換工作大同小(xiao)異，首先(xian)拆前需確認電(dian)機處于檢修狀態，擰下(xia)加油螺塞，用吸(xi)管把密封座(zuo)腔內的潤滑油吸(xi)出(chu)。準備好放置泵零(ling)件(jian)的工作臺及(ji)拆裝工具，切勿任(ren)意亂放亂用，避免碰(peng)壞泵的零(ling)部(bu)件(jian)。

　　拆對分(fen)式聯(lian)軸(zhou)器(qi)：先(xian)把聯(lian)軸(zhou)器(qi)的固(gu)定內(nei)六(liu)角螺釘擰下來，再輕輕把聯(lian)軸(zhou)器(qi)的一(yi)半(ban)從(cong)軸(zhou)上慢(man)慢(man)拉下，注(zhu)意不要掉了，再用(yong)梅花(hua)扳手擰下泵(beng)軸(zhou)吊緊螺栓和擋塊，讓葉輪慢(man)慢(man)下沉(chen)至泵(beng)體，然(ran)后拆下另外一(yi)半(ban)聯(lian)軸(zhou)器(qi)，拿(na)下泵(beng)軸(zhou)擋圈。

　　拆卸延川機械密封：抓住密封彈(dan)簧順(shun)著泵軸往上提，就能拆下來(lai)了。

　　拆卸(xie)并(bing)清洗(xi)軸(zhou)(zhou)承座(zuo)：先(xian)輕輕松(song)動一下(xia)軸(zhou)(zhou)承座(zuo)后用拆卸(xie)螺栓頂起(qi)軸(zhou)(zhou)承座(zuo)，并(bing)且(qie)沿(yan)著泵軸(zhou)(zhou)往上提(ti)而卸(xie)下(xia)，再用噴氣燃料(liao)清洗(xi)軸(zhou)(zhou)承及座(zuo)，裝(zhuang)前晾(liang)干并(bing)涂抹(mo)少(shao)許(xu)20號機械(xie)油用來潤滑保護(hu)。

　　拆密封(feng)(feng)座：擰(ning)下密封(feng)(feng)座壓(ya)緊螺(luo)母，輕(qing)輕(qing)卸下密封(feng)(feng)座并清洗(xi)。

　　延川機械密封裝(zhuang)(zhuang)配(pei)：在動(dong)、靜環(huan)鏡面上涂一層潔凈的20號潤滑油(you)(you)，導軸(zhou)(zhou)承座(zuo)也抹(mo)上潤滑油(you)(you)，先把靜環(huan)輕輕定位裝(zhuang)(zhuang)入導軸(zhou)(zhou)承座(zuo)，再(zai)在泵軸(zhou)(zhou)上抹(mo)上潤滑油(you)(you)，把動(dong)環(huan)部(bu)分(fen)輕輕裝(zhuang)(zhuang)入泵軸(zhou)(zhou)上，用(yong)手(shou)輕推密封(feng)環(huan)應能伸縮自如，注意動(dong)、靜環(huan)部(bu)分(fen)的防轉部(bu)位需裝(zhuang)(zhuang)配(pei)到(dao)位。

　　裝(zhuang)聯(lian)軸器(qi)：在電(dian)機軸頭上裝(zhuang)上擋圈，裝(zhuang)上一(yi)(yi)半聯(lian)軸器(qi)，再在泵(beng)軸端和聯(lian)軸器(qi)槽內(nei)裝(zhuang)上擋塊并用梅(mei)花(hua)扳手擰緊螺(luo)栓(shuan)；再裝(zhuang)上另一(yi)(yi)半聯(lian)軸器(qi)擰上內(nei)六角螺(luo)釘。安裝(zhuang)聯(lian)軸器(qi)正確的檢查(cha)要求：對分式聯(lian)軸器(qi)上下間隙需要均勻，用手盤動(dong)聯(lian)軸器(qi)幾圈檢查(cha)轉動(dong)的靈(ling)活(huo)性(xing)。

　　裝(zhuang)密(mi)封座(zuo)：先將密(mi)封座(zuo)裝(zhuang)入橡膠(jiao)油封，再(zai)把(ba)密(mi)封座(zuo)裝(zhuang)入泵(beng)蓋(gai)并(bing)(bing)壓(ya)(ya)在軸承(cheng)座(zuo)上，擰緊螺(luo)母，確保所(suo)有安裝(zhuang)螺(luo)釘(ding)緊固。當安裝(zhuang)螺(luo)釘(ding)被用(yong)作密(mi)封與軸之(zhi)間(jian)(jian)的驅動時(shi)(shi)，軸應打埋頭孔來(lai)加固連接(jie)，緊固壓(ya)(ya)蓋(gai)螺(luo)栓(shuan)時(shi)(shi)應該平穩(wen)緊固，并(bing)(bing)且不(bu)要使壓(ya)(ya)蓋(gai)受(shou)彈力。在可能的地(di)方使用(yong)4個(ge)以上螺(luo)釘(ding)的等間(jian)(jian)距壓(ya)(ya)蓋(gai)，緊固壓(ya)(ya)蓋(gai)螺(luo)栓(shuan)時(shi)(shi)，用(yong)塞尺檢查軸與壓(ya)(ya)蓋(gai)之(zhi)間(jian)(jian)的間(jian)(jian)隙，這在密(mi)封腔對(dui)壓(ya)(ya)蓋(gai)不(bu)導向時(shi)(shi)，顯得特(te)別重要，因為壓(ya)(ya)蓋(gai)必須(xu)對(dui)中。
