紅原機械密封利用(yong)機械(xie)(xie)(xie)方(fang)式傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)力和運(yun)(yun)動(dong)(dong)(dong)的(de)(de)(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong),機械(xie)(xie)(xie)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)在機械(xie)(xie)(xie)工程中(zhong)應用(yong)非常(chang)廣泛,有多種形式,主要包括皮帶傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、齒(chi)(chi)輪傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、蝸桿蝸輪傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、齒(chi)(chi)輪齒(chi)(chi)條傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)和螺旋傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)等。齒(chi)(chi)輪傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)能夠用(yong)于(yu)大(da)功(gong)率的(de)(de)(de)場(chang)合(he),傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)比準(zhun)確(que),但一(yi)般要求較(jiao)高的(de)(de)(de)制造精度和安裝精度。還(huan)有一(yi)類是靠機件間的(de)(de)(de)摩擦力傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)力和運(yun)(yun)動(dong)(dong)(dong)的(de)(de)(de)摩擦傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong),包括帶傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)和摩擦輪傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)等。摩擦傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)容易(yi)實現無級變速,可以(yi)適應軸間距較(jiao)大(da)的(de)(de)(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)場(chang)合(he),而過載打(da)滑還(huan)能起(qi)到緩沖和保(bao)護傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)裝置的(de)(de)(de)作(zuo)用(yong),但這種傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)一(yi)般不能用(yong)于(yu)大(da)功(gong)率的(de)(de)(de)場(chang)合(he),也不能保(bao)證準(zhun)確(que)的(de)(de)(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)比。
傳動形式多,但是紅原機械密封的更換(huan)工作大同小異,首先拆前需(xu)確認電(dian)機(ji)處(chu)于(yu)檢修狀態,擰下加油螺塞,用吸(xi)(xi)管把密(mi)封座腔內的潤滑(hua)油吸(xi)(xi)出。準備(bei)好放置(zhi)泵(beng)零件的工作臺及(ji)拆裝工具,切勿任意(yi)亂放亂用,避免碰壞泵(beng)的零部(bu)件。
拆對(dui)分(fen)式(shi)聯軸(zhou)器:先(xian)把聯軸(zhou)器的(de)(de)固定(ding)內六(liu)角(jiao)螺釘擰下來(lai),再(zai)輕(qing)輕(qing)把聯軸(zhou)器的(de)(de)一半從(cong)軸(zhou)上慢(man)慢(man)拉下,注意(yi)不(bu)要掉了,再(zai)用(yong)梅(mei)花(hua)扳手(shou)擰下泵(beng)軸(zhou)吊緊(jin)螺栓(shuan)和擋塊,讓葉輪慢(man)慢(man)下沉至泵(beng)體,然后拆下另外(wai)一半聯軸(zhou)器,拿下泵(beng)軸(zhou)擋圈(quan)。
拆卸紅原機械密封:抓住(zhu)密封彈簧順著泵軸往上提,就能拆下來了。
拆(chai)卸(xie)并(bing)清洗軸(zhou)(zhou)承座(zuo):先(xian)輕輕松動一下軸(zhou)(zhou)承座(zuo)后用拆(chai)卸(xie)螺栓頂起軸(zhou)(zhou)承座(zuo),并(bing)且沿著泵軸(zhou)(zhou)往(wang)上(shang)提(ti)而卸(xie)下,再用噴氣燃料清洗軸(zhou)(zhou)承及座(zuo),裝前晾(liang)干并(bing)涂(tu)抹少(shao)許20號(hao)機械油用來(lai)潤滑保護(hu)。
拆密(mi)封座:擰下(xia)密(mi)封座壓(ya)緊螺母,輕輕卸下(xia)密(mi)封座并清洗。
紅原機械密封裝(zhuang)配:在動、靜環鏡(jing)面上涂一(yi)層(ceng)潔凈的20號潤(run)滑油(you)(you),導軸(zhou)(zhou)承座也抹(mo)上潤(run)滑油(you)(you),先把靜環輕(qing)輕(qing)定位裝(zhuang)入(ru)導軸(zhou)(zhou)承座,再在泵軸(zhou)(zhou)上抹(mo)上潤(run)滑油(you)(you),把動環部分(fen)輕(qing)輕(qing)裝(zhuang)入(ru)泵軸(zhou)(zhou)上,用(yong)手輕(qing)推密封環應能伸縮(suo)自如,注意動、靜環部分(fen)的防轉部位需裝(zhuang)配到位。
裝聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi):在(zai)電機軸(zhou)(zhou)(zhou)頭(tou)上(shang)裝上(shang)擋圈,裝上(shang)一半聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi),再在(zai)泵軸(zhou)(zhou)(zhou)端和聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)槽內(nei)裝上(shang)擋塊并用梅花(hua)扳手(shou)擰緊螺栓;再裝上(shang)另一半聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)擰上(shang)內(nei)六角(jiao)螺釘。安裝聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)正確的(de)檢(jian)查(cha)(cha)要求:對分式聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)上(shang)下間隙需要均勻,用手(shou)盤動聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)幾(ji)圈檢(jian)查(cha)(cha)轉動的(de)靈活性。
裝(zhuang)(zhuang)密封(feng)座:先將密封(feng)座裝(zhuang)(zhuang)入(ru)橡膠油封(feng),再把密封(feng)座裝(zhuang)(zhuang)入(ru)泵蓋(gai)(gai)(gai)并壓(ya)(ya)在軸承(cheng)座上(shang)(shang),擰(ning)緊螺母,確保所(suo)有安(an)裝(zhuang)(zhuang)螺釘(ding)(ding)緊固(gu)。當安(an)裝(zhuang)(zhuang)螺釘(ding)(ding)被用(yong)作密封(feng)與軸之(zhi)間(jian)(jian)(jian)的(de)驅動時(shi),軸應(ying)打(da)埋(mai)頭孔來加固(gu)連(lian)接,緊固(gu)壓(ya)(ya)蓋(gai)(gai)(gai)螺栓(shuan)時(shi)應(ying)該平穩緊固(gu),并且不要使壓(ya)(ya)蓋(gai)(gai)(gai)受彈力。在可能的(de)地(di)方使用(yong)4個以(yi)上(shang)(shang)螺釘(ding)(ding)的(de)等(deng)間(jian)(jian)(jian)距壓(ya)(ya)蓋(gai)(gai)(gai),緊固(gu)壓(ya)(ya)蓋(gai)(gai)(gai)螺栓(shuan)時(shi),用(yong)塞(sai)尺檢查軸與壓(ya)(ya)蓋(gai)(gai)(gai)之(zhi)間(jian)(jian)(jian)的(de)間(jian)(jian)(jian)隙,這在密封(feng)腔對壓(ya)(ya)蓋(gai)(gai)(gai)不導(dao)向(xiang)時(shi),顯得特別重要,因為壓(ya)(ya)蓋(gai)(gai)(gai)必須對中。
