海寧機械密封利用(yong)(yong)機(ji)(ji)械方(fang)式傳(chuan)(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)力(li)和運動(dong)(dong)(dong)(dong)(dong)的(de)(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong),機(ji)(ji)械傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)在機(ji)(ji)械工程(cheng)中(zhong)應用(yong)(yong)非常廣泛,有多種形式,主要(yao)包括皮帶傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、蝸(gua)(gua)桿蝸(gua)(gua)輪(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)(lun)齒(chi)條傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和螺旋傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等。齒(chi)輪(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)能(neng)夠(gou)用(yong)(yong)于(yu)大功率(lv)的(de)(de)場(chang)(chang)合,傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比準確(que),但一般要(yao)求較高的(de)(de)制造精度(du)(du)和安裝精度(du)(du)。還(huan)有一類是(shi)靠(kao)機(ji)(ji)件間(jian)的(de)(de)摩擦力(li)傳(chuan)(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)力(li)和運動(dong)(dong)(dong)(dong)(dong)的(de)(de)摩擦傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong),包括帶傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和摩擦輪(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等。摩擦傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)容易實(shi)現無級變速,可以適應軸間(jian)距(ju)較大的(de)(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)場(chang)(chang)合,而過載打(da)滑還(huan)能(neng)起到緩沖(chong)和保(bao)護傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)裝置(zhi)的(de)(de)作用(yong)(yong),但這種傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)一般不能(neng)用(yong)(yong)于(yu)大功率(lv)的(de)(de)場(chang)(chang)合,也不能(neng)保(bao)證準確(que)的(de)(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比。
傳動形式多,但是海寧機械密封的(de)(de)更換工作(zuo)大同小異,首先拆前需(xu)確(que)認電機處于檢修狀態,擰(ning)下(xia)加油螺塞,用吸管把密封座腔內的(de)(de)潤滑油吸出。準備(bei)好放置泵零(ling)件的(de)(de)工作(zuo)臺及拆裝工具(ju),切勿任意亂(luan)放亂(luan)用,避免碰壞泵的(de)(de)零(ling)部件。
拆對分式聯(lian)(lian)軸(zhou)(zhou)器:先把聯(lian)(lian)軸(zhou)(zhou)器的(de)固定(ding)內(nei)六角(jiao)螺釘擰下(xia)來,再輕(qing)(qing)輕(qing)(qing)把聯(lian)(lian)軸(zhou)(zhou)器的(de)一半(ban)從軸(zhou)(zhou)上慢(man)(man)(man)慢(man)(man)(man)拉下(xia),注意不要(yao)掉了,再用梅(mei)花扳(ban)手擰下(xia)泵(beng)軸(zhou)(zhou)吊(diao)緊螺栓和擋(dang)塊,讓葉(xie)輪慢(man)(man)(man)慢(man)(man)(man)下(xia)沉(chen)至泵(beng)體,然后(hou)拆下(xia)另外一半(ban)聯(lian)(lian)軸(zhou)(zhou)器,拿下(xia)泵(beng)軸(zhou)(zhou)擋(dang)圈(quan)。
拆卸海寧機械密封:抓住(zhu)密封彈簧順著泵(beng)軸往上提,就能拆下(xia)來(lai)了。
拆卸并(bing)清洗軸(zhou)(zhou)承座(zuo):先輕(qing)(qing)輕(qing)(qing)松動一下軸(zhou)(zhou)承座(zuo)后用拆卸螺(luo)栓頂起(qi)軸(zhou)(zhou)承座(zuo),并(bing)且沿著泵軸(zhou)(zhou)往上(shang)提而卸下,再用噴氣(qi)燃料(liao)清洗軸(zhou)(zhou)承及(ji)座(zuo),裝前晾干并(bing)涂抹少許20號機械油(you)用來潤滑保護。
拆(chai)密封座:擰下(xia)密封座壓緊螺母,輕(qing)輕(qing)卸(xie)下(xia)密封座并清洗(xi)。
海寧機械密封裝配:在動、靜環(huan)鏡面上(shang)(shang)(shang)涂一層潔凈的(de)20號(hao)潤滑油(you)(you),導(dao)軸承座也抹(mo)(mo)上(shang)(shang)(shang)潤滑油(you)(you),先把(ba)(ba)靜環(huan)輕(qing)(qing)輕(qing)(qing)定位裝入導(dao)軸承座,再在泵軸上(shang)(shang)(shang)抹(mo)(mo)上(shang)(shang)(shang)潤滑油(you)(you),把(ba)(ba)動環(huan)部(bu)分輕(qing)(qing)輕(qing)(qing)裝入泵軸上(shang)(shang)(shang),用手輕(qing)(qing)推密封環(huan)應能伸(shen)縮自(zi)如,注(zhu)意(yi)動、靜環(huan)部(bu)分的(de)防轉部(bu)位需(xu)裝配到位。
裝(zhuang)(zhuang)(zhuang)聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi):在電(dian)機(ji)軸(zhou)(zhou)(zhou)頭上裝(zhuang)(zhuang)(zhuang)上擋圈,裝(zhuang)(zhuang)(zhuang)上一(yi)(yi)半聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi),再在泵軸(zhou)(zhou)(zhou)端和聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)槽內裝(zhuang)(zhuang)(zhuang)上擋塊并用梅(mei)花扳手(shou)擰(ning)緊螺(luo)栓(shuan);再裝(zhuang)(zhuang)(zhuang)上另一(yi)(yi)半聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)擰(ning)上內六角螺(luo)釘。安裝(zhuang)(zhuang)(zhuang)聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)正確的檢(jian)查要求:對分式聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)上下間(jian)隙需要均勻,用手(shou)盤動聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)幾(ji)圈檢(jian)查轉動的靈活性(xing)。
裝(zhuang)(zhuang)(zhuang)密(mi)(mi)封(feng)座:先將密(mi)(mi)封(feng)座裝(zhuang)(zhuang)(zhuang)入(ru)橡(xiang)膠(jiao)油封(feng),再把密(mi)(mi)封(feng)座裝(zhuang)(zhuang)(zhuang)入(ru)泵蓋并壓(ya)在軸(zhou)承座上,擰緊(jin)(jin)螺(luo)母(mu),確(que)保所有安(an)裝(zhuang)(zhuang)(zhuang)螺(luo)釘緊(jin)(jin)固(gu)(gu)。當安(an)裝(zhuang)(zhuang)(zhuang)螺(luo)釘被用(yong)作密(mi)(mi)封(feng)與軸(zhou)之間(jian)的驅(qu)動時(shi),軸(zhou)應(ying)打埋頭(tou)孔來加固(gu)(gu)連接,緊(jin)(jin)固(gu)(gu)壓(ya)蓋螺(luo)栓(shuan)時(shi)應(ying)該平穩(wen)緊(jin)(jin)固(gu)(gu),并且不要使壓(ya)蓋受(shou)彈力(li)。在可能(neng)的地方使用(yong)4個以上螺(luo)釘的等間(jian)距壓(ya)蓋,緊(jin)(jin)固(gu)(gu)壓(ya)蓋螺(luo)栓(shuan)時(shi),用(yong)塞尺檢查軸(zhou)與壓(ya)蓋之間(jian)的間(jian)隙,這在密(mi)(mi)封(feng)腔對壓(ya)蓋不導向時(shi),顯得特別重要,因為壓(ya)蓋必(bi)須對中。
