雙流機械密封利用(yong)機械方(fang)式(shi)(shi)傳(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)(dong)力(li)和運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)，機械傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)在機械工程中應用(yong)非常廣(guang)泛，有(you)(you)多種(zhong)形(xing)式(shi)(shi)，主要(yao)包括皮(pi)帶(dai)(dai)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、齒輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、蝸(gua)桿(gan)蝸(gua)輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、齒輪(lun)齒條傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)和螺旋傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)等。齒輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)能(neng)夠用(yong)于(yu)大(da)功(gong)率的(de)(de)(de)場(chang)合，傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比(bi)準(zhun)確(que)，但一般要(yao)求較高的(de)(de)(de)制造精度(du)和安裝精度(du)。還有(you)(you)一類是(shi)靠機件間的(de)(de)(de)摩擦力(li)傳(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)(dong)力(li)和運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)摩擦傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)，包括帶(dai)(dai)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)和摩擦輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)等。摩擦傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)容易實(shi)現無級(ji)變速，可以適應軸間距較大(da)的(de)(de)(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)場(chang)合，而(er)過載打滑還能(neng)起到緩沖(chong)和保護(hu)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)裝置的(de)(de)(de)作(zuo)用(yong)，但這種(zhong)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)一般不能(neng)用(yong)于(yu)大(da)功(gong)率的(de)(de)(de)場(chang)合，也不能(neng)保證(zheng)準(zhun)確(que)的(de)(de)(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比(bi)。

　　傳動形式多，但是雙流機械密封的(de)更換(huan)工(gong)(gong)作(zuo)大同小(xiao)異，首先拆前需確認電機處于檢修狀態(tai)，擰(ning)下加油螺(luo)塞，用(yong)吸(xi)管(guan)把密封座(zuo)腔(qiang)內(nei)的(de)潤(run)滑油吸(xi)出。準(zhun)備(bei)好放(fang)置泵零(ling)件的(de)工(gong)(gong)作(zuo)臺及拆裝工(gong)(gong)具，切勿任意亂(luan)放(fang)亂(luan)用(yong)，避免碰壞(huai)泵的(de)零(ling)部件。

　　拆對分式聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)：先(xian)把聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)的(de)固(gu)定內六角螺釘(ding)擰下(xia)來，再(zai)輕(qing)輕(qing)把聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)的(de)一(yi)半從軸(zhou)(zhou)上慢(man)(man)慢(man)(man)拉(la)下(xia)，注意不要掉了，再(zai)用梅(mei)花扳手擰下(xia)泵軸(zhou)(zhou)吊緊螺栓和擋塊(kuai)，讓葉輪慢(man)(man)慢(man)(man)下(xia)沉至(zhi)泵體，然后拆下(xia)另(ling)外一(yi)半聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)，拿下(xia)泵軸(zhou)(zhou)擋圈(quan)。

　　拆卸雙流機械密封：抓住密封彈簧順著泵軸往上提，就能(neng)拆下來了(le)。

　　拆卸(xie)并清(qing)洗(xi)軸(zhou)承(cheng)座(zuo)：先輕輕松動一下(xia)軸(zhou)承(cheng)座(zuo)后用(yong)拆卸(xie)螺栓頂起軸(zhou)承(cheng)座(zuo)，并且沿著(zhu)泵軸(zhou)往上提(ti)而卸(xie)下(xia)，再用(yong)噴氣燃料清(qing)洗(xi)軸(zhou)承(cheng)及(ji)座(zuo)，裝前晾干(gan)并涂抹少許20號機械油(you)用(yong)來潤滑保護。

　　拆(chai)密封(feng)(feng)座(zuo)：擰下密封(feng)(feng)座(zuo)壓緊螺(luo)母，輕(qing)輕(qing)卸(xie)下密封(feng)(feng)座(zuo)并清洗。

　　雙流機械密封裝(zhuang)配(pei)：在動(dong)、靜環(huan)鏡(jing)面(mian)上(shang)涂(tu)一層潔凈的20號潤(run)(run)滑(hua)油(you)，導軸(zhou)(zhou)承(cheng)座也抹(mo)上(shang)潤(run)(run)滑(hua)油(you)，先(xian)把(ba)靜環(huan)輕(qing)(qing)輕(qing)(qing)定位裝(zhuang)入(ru)導軸(zhou)(zhou)承(cheng)座，再在泵(beng)軸(zhou)(zhou)上(shang)抹(mo)上(shang)潤(run)(run)滑(hua)油(you)，把(ba)動(dong)環(huan)部分輕(qing)(qing)輕(qing)(qing)裝(zhuang)入(ru)泵(beng)軸(zhou)(zhou)上(shang)，用手輕(qing)(qing)推(tui)密封環(huan)應(ying)能伸縮自如，注(zhu)意動(dong)、靜環(huan)部分的防轉(zhuan)部位需裝(zhuang)配(pei)到位。

　　裝聯軸(zhou)(zhou)(zhou)器(qi)(qi)：在電機(ji)軸(zhou)(zhou)(zhou)頭上(shang)(shang)裝上(shang)(shang)擋(dang)圈(quan)(quan)，裝上(shang)(shang)一半聯軸(zhou)(zhou)(zhou)器(qi)(qi)，再在泵軸(zhou)(zhou)(zhou)端(duan)和聯軸(zhou)(zhou)(zhou)器(qi)(qi)槽(cao)內裝上(shang)(shang)擋(dang)塊并用(yong)梅花扳手(shou)擰緊螺(luo)栓；再裝上(shang)(shang)另(ling)一半聯軸(zhou)(zhou)(zhou)器(qi)(qi)擰上(shang)(shang)內六(liu)角螺(luo)釘。安裝聯軸(zhou)(zhou)(zhou)器(qi)(qi)正(zheng)確的檢(jian)查要求：對分式聯軸(zhou)(zhou)(zhou)器(qi)(qi)上(shang)(shang)下間隙需要均勻，用(yong)手(shou)盤動聯軸(zhou)(zhou)(zhou)器(qi)(qi)幾圈(quan)(quan)檢(jian)查轉動的靈活(huo)性。

　　裝密封(feng)座(zuo)：先將(jiang)密封(feng)座(zuo)裝入(ru)橡(xiang)膠油封(feng)，再把密封(feng)座(zuo)裝入(ru)泵蓋并壓(ya)在軸(zhou)承座(zuo)上，擰緊(jin)(jin)螺母，確保所(suo)有安裝螺釘(ding)緊(jin)(jin)固(gu)(gu)(gu)。當安裝螺釘(ding)被用作密封(feng)與(yu)軸(zhou)之間(jian)的驅動(dong)時，軸(zhou)應打(da)埋(mai)頭孔(kong)來加固(gu)(gu)(gu)連接(jie)，緊(jin)(jin)固(gu)(gu)(gu)壓(ya)蓋螺栓(shuan)時應該平穩(wen)緊(jin)(jin)固(gu)(gu)(gu)，并且不要(yao)使壓(ya)蓋受彈力。在可能的地方使用4個以(yi)上螺釘(ding)的等間(jian)距壓(ya)蓋，緊(jin)(jin)固(gu)(gu)(gu)壓(ya)蓋螺栓(shuan)時，用塞(sai)尺(chi)檢查(cha)軸(zhou)與(yu)壓(ya)蓋之間(jian)的間(jian)隙，這在密封(feng)腔對壓(ya)蓋不導向時，顯得特別重要(yao)，因為(wei)壓(ya)蓋必須對中。
