成都機械密封利用(yong)機械(xie)方式(shi)傳(chuan)(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)力(li)和運動(dong)(dong)(dong)(dong)的(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong),機械(xie)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)在機械(xie)工(gong)程中應用(yong)非常廣(guang)泛,有多種形(xing)式(shi),主要包括(kuo)皮(pi)帶傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、蝸(gua)桿蝸(gua)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒(chi)輪(lun)齒(chi)條(tiao)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)和螺旋(xuan)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)等(deng)。齒(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)能(neng)夠用(yong)于(yu)大(da)(da)功率(lv)的(de)場合(he)(he),傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)比(bi)準確(que),但(dan)一般要求較(jiao)高的(de)制造(zao)精(jing)度和安(an)裝精(jing)度。還(huan)(huan)有一類是靠機件間(jian)的(de)摩擦力(li)傳(chuan)(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)力(li)和運動(dong)(dong)(dong)(dong)的(de)摩擦傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong),包括(kuo)帶傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)和摩擦輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)等(deng)。摩擦傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)容易實現無級變(bian)速,可以適(shi)應軸間(jian)距較(jiao)大(da)(da)的(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)場合(he)(he),而(er)過(guo)載打(da)滑還(huan)(huan)能(neng)起到緩(huan)沖和保護傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)裝置(zhi)的(de)作用(yong),但(dan)這種傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)一般不能(neng)用(yong)于(yu)大(da)(da)功率(lv)的(de)場合(he)(he),也不能(neng)保證(zheng)準確(que)的(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)比(bi)。
傳動形式多,但是成都機械密封的(de)更(geng)換工(gong)作(zuo)大同小異,首先拆(chai)前需確認電機處于檢修狀態,擰下加油(you)螺塞,用吸管把密(mi)封座腔內的(de)潤滑油(you)吸出。準備好放置(zhi)泵零(ling)件的(de)工(gong)作(zuo)臺及(ji)拆(chai)裝工(gong)具,切勿任意(yi)亂放亂用,避(bi)免碰壞泵的(de)零(ling)部件。
拆(chai)對分式聯軸(zhou)(zhou)器(qi):先把聯軸(zhou)(zhou)器(qi)的固定內六角螺(luo)(luo)釘擰(ning)(ning)下來(lai),再(zai)輕輕把聯軸(zhou)(zhou)器(qi)的一半從軸(zhou)(zhou)上慢慢拉下,注(zhu)意(yi)不要(yao)掉了,再(zai)用(yong)梅花扳手擰(ning)(ning)下泵軸(zhou)(zhou)吊緊螺(luo)(luo)栓和擋塊,讓(rang)葉輪慢慢下沉至泵體(ti),然后拆(chai)下另(ling)外一半聯軸(zhou)(zhou)器(qi),拿下泵軸(zhou)(zhou)擋圈。
拆卸成都機械密封:抓住密(mi)封彈簧順著泵軸(zhou)往上提,就能拆下來了(le)。
拆卸并清洗軸(zhou)承座(zuo):先輕(qing)(qing)輕(qing)(qing)松動一下軸(zhou)承座(zuo)后用(yong)(yong)拆卸螺栓(shuan)頂(ding)起軸(zhou)承座(zuo),并且沿著(zhu)泵軸(zhou)往上(shang)提而卸下,再用(yong)(yong)噴氣燃(ran)料清洗軸(zhou)承及座(zuo),裝前晾干(gan)并涂抹少許(xu)20號機械(xie)油用(yong)(yong)來(lai)潤滑保護。
拆密封座:擰下密封座壓(ya)緊螺母,輕輕卸下密封座并清(qing)洗(xi)。
成都機械密封裝(zhuang)配(pei)(pei):在動、靜環(huan)(huan)鏡面上(shang)涂一層潔凈的20號(hao)潤(run)滑(hua)油(you),導(dao)軸承(cheng)座也抹(mo)上(shang)潤(run)滑(hua)油(you),先把靜環(huan)(huan)輕(qing)(qing)輕(qing)(qing)定位裝(zhuang)入(ru)導(dao)軸承(cheng)座,再在泵軸上(shang)抹(mo)上(shang)潤(run)滑(hua)油(you),把動環(huan)(huan)部分輕(qing)(qing)輕(qing)(qing)裝(zhuang)入(ru)泵軸上(shang),用手(shou)輕(qing)(qing)推密封環(huan)(huan)應能伸(shen)縮自如,注意動、靜環(huan)(huan)部分的防轉部位需裝(zhuang)配(pei)(pei)到位。
裝(zhuang)(zhuang)聯(lian)軸(zhou)器(qi):在電機軸(zhou)頭(tou)上裝(zhuang)(zhuang)上擋(dang)圈(quan),裝(zhuang)(zhuang)上一半聯(lian)軸(zhou)器(qi),再(zai)在泵軸(zhou)端和聯(lian)軸(zhou)器(qi)槽內裝(zhuang)(zhuang)上擋(dang)塊并用梅花扳(ban)手擰緊螺栓;再(zai)裝(zhuang)(zhuang)上另(ling)一半聯(lian)軸(zhou)器(qi)擰上內六角螺釘。安(an)裝(zhuang)(zhuang)聯(lian)軸(zhou)器(qi)正(zheng)確(que)的檢查要求:對分(fen)式聯(lian)軸(zhou)器(qi)上下(xia)間隙需要均(jun)勻,用手盤動聯(lian)軸(zhou)器(qi)幾(ji)圈(quan)檢查轉動的靈活性。
裝(zhuang)密(mi)封座:先將(jiang)密(mi)封座裝(zhuang)入(ru)橡膠油封,再把密(mi)封座裝(zhuang)入(ru)泵蓋并(bing)壓(ya)在軸(zhou)承座上,擰緊(jin)螺(luo)(luo)母(mu),確保所有安裝(zhuang)螺(luo)(luo)釘(ding)(ding)(ding)緊(jin)固(gu)。當安裝(zhuang)螺(luo)(luo)釘(ding)(ding)(ding)被用作密(mi)封與軸(zhou)之間的驅(qu)動時,軸(zhou)應打埋頭孔來(lai)加(jia)固(gu)連接,緊(jin)固(gu)壓(ya)蓋螺(luo)(luo)栓時應該平穩緊(jin)固(gu),并(bing)且不要使(shi)壓(ya)蓋受(shou)彈(dan)力。在可能的地方(fang)使(shi)用4個以上螺(luo)(luo)釘(ding)(ding)(ding)的等間距(ju)壓(ya)蓋,緊(jin)固(gu)壓(ya)蓋螺(luo)(luo)栓時,用塞尺(chi)檢查軸(zhou)與壓(ya)蓋之間的間隙,這在密(mi)封腔(qiang)對壓(ya)蓋不導向時,顯得特別(bie)重要,因為壓(ya)蓋必須對中(zhong)。
