依安機械密封利用(yong)(yong)機(ji)械(xie)方式傳(chuan)(chuan)(chuan)遞動(dong)(dong)力和運動(dong)(dong)的(de)(de)(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong),機(ji)械(xie)傳(chuan)(chuan)(chuan)動(dong)(dong)在機(ji)械(xie)工程中應用(yong)(yong)非常(chang)廣泛,有(you)多種形(xing)式,主(zhu)要包括皮帶傳(chuan)(chuan)(chuan)動(dong)(dong)、齒(chi)(chi)輪(lun)(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)、鏈傳(chuan)(chuan)(chuan)動(dong)(dong)、蝸桿蝸輪(lun)(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)、齒(chi)(chi)輪(lun)(lun)齒(chi)(chi)條(tiao)傳(chuan)(chuan)(chuan)動(dong)(dong)和螺旋傳(chuan)(chuan)(chuan)動(dong)(dong)等。齒(chi)(chi)輪(lun)(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)能夠用(yong)(yong)于(yu)大功率(lv)的(de)(de)(de)(de)場合,傳(chuan)(chuan)(chuan)動(dong)(dong)比準確,但一(yi)(yi)般要求較高的(de)(de)(de)(de)制(zhi)造精(jing)度和安(an)裝精(jing)度。還(huan)有(you)一(yi)(yi)類是靠機(ji)件(jian)間(jian)的(de)(de)(de)(de)摩擦力傳(chuan)(chuan)(chuan)遞動(dong)(dong)力和運動(dong)(dong)的(de)(de)(de)(de)摩擦傳(chuan)(chuan)(chuan)動(dong)(dong),包括帶傳(chuan)(chuan)(chuan)動(dong)(dong)、繩傳(chuan)(chuan)(chuan)動(dong)(dong)和摩擦輪(lun)(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)等。摩擦傳(chuan)(chuan)(chuan)動(dong)(dong)容(rong)易實(shi)現無級變速,可以適應軸間(jian)距較大的(de)(de)(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)場合,而(er)過載打滑還(huan)能起到緩(huan)沖和保護(hu)傳(chuan)(chuan)(chuan)動(dong)(dong)裝置的(de)(de)(de)(de)作(zuo)用(yong)(yong),但這種傳(chuan)(chuan)(chuan)動(dong)(dong)一(yi)(yi)般不(bu)能用(yong)(yong)于(yu)大功率(lv)的(de)(de)(de)(de)場合,也不(bu)能保證準確的(de)(de)(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)比。
傳動形式多,但是依安機械密封的(de)(de)更換工(gong)作大同小異,首先拆(chai)前需確認電機處于(yu)檢修狀態,擰下(xia)加油螺塞,用吸(xi)管把密(mi)封座腔內的(de)(de)潤滑油吸(xi)出。準備好放(fang)置(zhi)泵(beng)零件(jian)的(de)(de)工(gong)作臺及拆(chai)裝工(gong)具,切勿(wu)任意亂放(fang)亂用,避(bi)免碰壞泵(beng)的(de)(de)零部件(jian)。
拆對(dui)分式聯軸(zhou)器:先把聯軸(zhou)器的固定內六角螺釘擰下來,再輕(qing)輕(qing)把聯軸(zhou)器的一半從軸(zhou)上慢(man)慢(man)拉下,注意不要掉(diao)了,再用梅花(hua)扳手擰下泵軸(zhou)吊緊螺栓和擋(dang)塊,讓葉輪慢(man)慢(man)下沉至泵體(ti),然后拆下另外(wai)一半聯軸(zhou)器,拿下泵軸(zhou)擋(dang)圈。
拆卸依安機械密封:抓住密封彈(dan)簧順(shun)著泵軸往上(shang)提,就(jiu)能拆下來了。
拆卸并(bing)(bing)清(qing)洗軸承(cheng)座(zuo):先輕輕松動一下軸承(cheng)座(zuo)后用拆卸螺栓頂起軸承(cheng)座(zuo),并(bing)(bing)且沿(yan)著泵軸往上(shang)提(ti)而卸下,再用噴氣燃料清(qing)洗軸承(cheng)及座(zuo),裝前晾干并(bing)(bing)涂抹(mo)少許(xu)20號機械油用來潤滑保(bao)護。
拆密封座(zuo)(zuo):擰下密封座(zuo)(zuo)壓緊螺母,輕輕卸下密封座(zuo)(zuo)并清洗。
依安機械密封裝(zhuang)配(pei):在動(dong)、靜環(huan)鏡面(mian)上涂(tu)一層潔凈的(de)20號潤(run)滑(hua)油(you)(you),導(dao)軸(zhou)(zhou)承座(zuo)也抹(mo)上潤(run)滑(hua)油(you)(you),先把靜環(huan)輕(qing)輕(qing)定位裝(zhuang)入(ru)導(dao)軸(zhou)(zhou)承座(zuo),再在泵軸(zhou)(zhou)上抹(mo)上潤(run)滑(hua)油(you)(you),把動(dong)環(huan)部(bu)(bu)分輕(qing)輕(qing)裝(zhuang)入(ru)泵軸(zhou)(zhou)上,用手輕(qing)推密(mi)封環(huan)應能(neng)伸(shen)縮自如,注意動(dong)、靜環(huan)部(bu)(bu)分的(de)防轉部(bu)(bu)位需裝(zhuang)配(pei)到位。
裝(zhuang)聯軸(zhou)器:在(zai)電機軸(zhou)頭(tou)上裝(zhuang)上擋圈,裝(zhuang)上一半聯軸(zhou)器,再在(zai)泵軸(zhou)端和聯軸(zhou)器槽內(nei)裝(zhuang)上擋塊(kuai)并用梅花扳手擰緊螺(luo)栓;再裝(zhuang)上另一半聯軸(zhou)器擰上內(nei)六角螺(luo)釘(ding)。安裝(zhuang)聯軸(zhou)器正確的檢查要(yao)求:對(dui)分式聯軸(zhou)器上下間隙(xi)需要(yao)均(jun)勻,用手盤(pan)動(dong)聯軸(zhou)器幾圈檢查轉(zhuan)動(dong)的靈活性。
裝密(mi)封(feng)座(zuo):先將密(mi)封(feng)座(zuo)裝入橡膠油封(feng),再把密(mi)封(feng)座(zuo)裝入泵蓋(gai)(gai)并壓(ya)在(zai)軸(zhou)(zhou)承座(zuo)上(shang),擰緊(jin)螺(luo)(luo)母(mu),確保(bao)所有安裝螺(luo)(luo)釘(ding)緊(jin)固(gu)。當安裝螺(luo)(luo)釘(ding)被(bei)用(yong)(yong)作(zuo)密(mi)封(feng)與軸(zhou)(zhou)之(zhi)間(jian)(jian)(jian)(jian)的(de)(de)驅動時,軸(zhou)(zhou)應(ying)打埋頭孔來(lai)加固(gu)連接(jie),緊(jin)固(gu)壓(ya)蓋(gai)(gai)螺(luo)(luo)栓時應(ying)該平穩緊(jin)固(gu),并且不要使(shi)壓(ya)蓋(gai)(gai)受(shou)彈力(li)。在(zai)可能(neng)的(de)(de)地方使(shi)用(yong)(yong)4個以上(shang)螺(luo)(luo)釘(ding)的(de)(de)等(deng)間(jian)(jian)(jian)(jian)距壓(ya)蓋(gai)(gai),緊(jin)固(gu)壓(ya)蓋(gai)(gai)螺(luo)(luo)栓時,用(yong)(yong)塞尺檢查軸(zhou)(zhou)與壓(ya)蓋(gai)(gai)之(zhi)間(jian)(jian)(jian)(jian)的(de)(de)間(jian)(jian)(jian)(jian)隙,這在(zai)密(mi)封(feng)腔對壓(ya)蓋(gai)(gai)不導(dao)向(xiang)時,顯得特別重要,因(yin)為壓(ya)蓋(gai)(gai)必須對中。
