定襄機械密封利用(yong)機械(xie)(xie)方(fang)式(shi)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)力和(he)運動(dong)(dong)(dong)(dong)的(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong),機械(xie)(xie)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)在機械(xie)(xie)工程中(zhong)應用(yong)非常廣(guang)泛(fan),有多種(zhong)形式(shi),主要(yao)包(bao)(bao)括(kuo)皮帶傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、蝸桿蝸輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒輪(lun)齒條(tiao)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)螺(luo)旋(xuan)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)等。齒輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)能夠用(yong)于大(da)功率的(de)場(chang)(chang)合,傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)比(bi)準確,但一(yi)般要(yao)求較高的(de)制造精度和(he)安(an)裝(zhuang)精度。還有一(yi)類是靠機件間的(de)摩(mo)擦(ca)(ca)力傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)力和(he)運動(dong)(dong)(dong)(dong)的(de)摩(mo)擦(ca)(ca)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong),包(bao)(bao)括(kuo)帶傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)摩(mo)擦(ca)(ca)輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)等。摩(mo)擦(ca)(ca)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)容易(yi)實現無(wu)級變速,可以適應軸間距(ju)較大(da)的(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)場(chang)(chang)合,而過載(zai)打滑還能起到緩沖和(he)保護傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)裝(zhuang)置的(de)作用(yong),但這種(zhong)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)一(yi)般不能用(yong)于大(da)功率的(de)場(chang)(chang)合,也不能保證準確的(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)比(bi)。
傳動形式多,但是定襄機械密封的更換工作大同(tong)小異,首先拆前需確認電機處于檢(jian)修(xiu)狀態,擰(ning)下(xia)加油螺塞,用(yong)吸(xi)(xi)管把密封座腔內的潤滑油吸(xi)(xi)出。準(zhun)備好放置(zhi)泵零(ling)件的工作臺及(ji)拆裝工具,切勿(wu)任意亂(luan)放亂(luan)用(yong),避免碰壞泵的零(ling)部件。
拆對分式聯(lian)軸器(qi)(qi):先把聯(lian)軸器(qi)(qi)的固定內(nei)六角螺釘(ding)擰下(xia)(xia)(xia)來,再輕輕把聯(lian)軸器(qi)(qi)的一半從軸上慢(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)泵軸吊緊螺栓和擋(dang)塊,讓葉輪慢(man)(man)慢(man)(man)下(xia)(xia)(xia)沉至泵體,然(ran)后拆下(xia)(xia)(xia)另外一半聯(lian)軸器(qi)(qi),拿下(xia)(xia)(xia)泵軸擋(dang)圈。
拆卸定襄機械密封:抓住(zhu)密封(feng)彈簧順著泵軸往上提(ti),就能拆下來了(le)。
拆卸(xie)并清洗(xi)軸承(cheng)座:先(xian)輕輕松動一下(xia)軸承(cheng)座后用(yong)拆卸(xie)螺(luo)栓頂起軸承(cheng)座,并且沿(yan)著泵(beng)軸往上提而卸(xie)下(xia),再用(yong)噴氣燃料清洗(xi)軸承(cheng)及座,裝(zhuang)前晾干(gan)并涂(tu)抹少(shao)許20號(hao)機(ji)械(xie)油用(yong)來潤滑保(bao)護。
拆密封座:擰下(xia)密封座壓(ya)緊螺母,輕(qing)輕(qing)卸下(xia)密封座并清洗(xi)。
定襄機械密封裝(zhuang)配:在動、靜(jing)環(huan)(huan)鏡面上(shang)涂(tu)一層潔凈的20號(hao)潤滑油,導軸(zhou)承座也抹(mo)上(shang)潤滑油,先把靜(jing)環(huan)(huan)輕(qing)(qing)輕(qing)(qing)定位裝(zhuang)入導軸(zhou)承座,再在泵軸(zhou)上(shang)抹(mo)上(shang)潤滑油,把動環(huan)(huan)部(bu)分輕(qing)(qing)輕(qing)(qing)裝(zhuang)入泵軸(zhou)上(shang),用(yong)手(shou)輕(qing)(qing)推(tui)密封環(huan)(huan)應(ying)能伸縮自如(ru),注意動、靜(jing)環(huan)(huan)部(bu)分的防轉部(bu)位需裝(zhuang)配到位。
裝(zhuang)(zhuang)聯(lian)軸(zhou)器(qi):在電機軸(zhou)頭(tou)上(shang)裝(zhuang)(zhuang)上(shang)擋圈,裝(zhuang)(zhuang)上(shang)一半聯(lian)軸(zhou)器(qi),再(zai)在泵(beng)軸(zhou)端和聯(lian)軸(zhou)器(qi)槽(cao)內裝(zhuang)(zhuang)上(shang)擋塊并(bing)用梅花扳手(shou)擰緊(jin)螺(luo)栓;再(zai)裝(zhuang)(zhuang)上(shang)另一半聯(lian)軸(zhou)器(qi)擰上(shang)內六角螺(luo)釘。安裝(zhuang)(zhuang)聯(lian)軸(zhou)器(qi)正確的檢查要求:對分(fen)式聯(lian)軸(zhou)器(qi)上(shang)下(xia)間(jian)隙(xi)需要均勻,用手(shou)盤動聯(lian)軸(zhou)器(qi)幾(ji)圈檢查轉動的靈(ling)活(huo)性。
裝密封(feng)(feng)座:先將密封(feng)(feng)座裝入橡膠油封(feng)(feng),再把(ba)密封(feng)(feng)座裝入泵蓋(gai)并壓(ya)(ya)(ya)在(zai)軸(zhou)承座上,擰緊螺母,確保所有安(an)裝螺釘緊固(gu)。當安(an)裝螺釘被用作密封(feng)(feng)與軸(zhou)之(zhi)間的(de)驅動時(shi),軸(zhou)應打埋頭孔(kong)來加固(gu)連接,緊固(gu)壓(ya)(ya)(ya)蓋(gai)螺栓(shuan)時(shi)應該(gai)平穩(wen)緊固(gu),并且不(bu)要(yao)使壓(ya)(ya)(ya)蓋(gai)受(shou)彈力。在(zai)可能的(de)地方使用4個以上螺釘的(de)等間距壓(ya)(ya)(ya)蓋(gai),緊固(gu)壓(ya)(ya)(ya)蓋(gai)螺栓(shuan)時(shi),用塞尺檢查軸(zhou)與壓(ya)(ya)(ya)蓋(gai)之(zhi)間的(de)間隙(xi),這在(zai)密封(feng)(feng)腔(qiang)對壓(ya)(ya)(ya)蓋(gai)不(bu)導向時(shi),顯(xian)得特別重要(yao),因(yin)為壓(ya)(ya)(ya)蓋(gai)必須對中。
