通河機械密封利用機械(xie)方式傳(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)力和(he)(he)運動(dong)(dong)(dong)(dong)的(de)(de)(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong),機械(xie)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)在機械(xie)工(gong)程中應(ying)用非常(chang)廣(guang)泛,有(you)多種形(xing)式,主(zhu)要包(bao)括(kuo)皮帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒(chi)輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、蝸(gua)桿蝸(gua)輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒(chi)輪齒(chi)條傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)(he)螺旋傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)等。齒(chi)輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)能(neng)(neng)夠用于大(da)功(gong)率的(de)(de)(de)(de)場(chang)合(he),傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)比(bi)準(zhun)確,但(dan)一(yi)(yi)般要求較(jiao)高的(de)(de)(de)(de)制造精度(du)和(he)(he)安裝精度(du)。還(huan)有(you)一(yi)(yi)類是(shi)靠機件(jian)間的(de)(de)(de)(de)摩(mo)擦(ca)力傳(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)力和(he)(he)運動(dong)(dong)(dong)(dong)的(de)(de)(de)(de)摩(mo)擦(ca)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong),包(bao)括(kuo)帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、繩(sheng)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)(he)摩(mo)擦(ca)輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)等。摩(mo)擦(ca)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)容易實現無級變速,可以適應(ying)軸間距較(jiao)大(da)的(de)(de)(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)場(chang)合(he),而過載打滑(hua)還(huan)能(neng)(neng)起(qi)到緩(huan)沖(chong)和(he)(he)保護傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)裝置(zhi)的(de)(de)(de)(de)作(zuo)用,但(dan)這種傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)一(yi)(yi)般不能(neng)(neng)用于大(da)功(gong)率的(de)(de)(de)(de)場(chang)合(he),也不能(neng)(neng)保證準(zhun)確的(de)(de)(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)比(bi)。
傳動形式多,但是通河機械密封的(de)更換工作大同小異,首先拆前(qian)需確認電機處于檢修狀態,擰(ning)下(xia)加油螺塞(sai),用吸(xi)管把(ba)密封座腔內的(de)潤滑油吸(xi)出。準備(bei)好放置泵(beng)零(ling)件的(de)工作臺(tai)及拆裝(zhuang)工具,切勿任意亂(luan)放亂(luan)用,避免碰壞(huai)泵(beng)的(de)零(ling)部(bu)件。
拆(chai)對(dui)分式聯軸(zhou)(zhou)(zhou)器(qi)(qi):先把聯軸(zhou)(zhou)(zhou)器(qi)(qi)的(de)固(gu)定內(nei)六角螺(luo)釘(ding)擰(ning)下(xia)(xia)(xia)來,再輕輕把聯軸(zhou)(zhou)(zhou)器(qi)(qi)的(de)一半從(cong)軸(zhou)(zhou)(zhou)上慢慢拉下(xia)(xia)(xia),注意不要掉了,再用梅花扳(ban)手(shou)擰(ning)下(xia)(xia)(xia)泵軸(zhou)(zhou)(zhou)吊緊螺(luo)栓和擋塊,讓(rang)葉輪(lun)慢慢下(xia)(xia)(xia)沉至泵體,然后(hou)拆(chai)下(xia)(xia)(xia)另外一半聯軸(zhou)(zhou)(zhou)器(qi)(qi),拿下(xia)(xia)(xia)泵軸(zhou)(zhou)(zhou)擋圈。
拆卸通河機械密封:抓住密封(feng)彈簧順(shun)著泵軸往上提,就(jiu)能拆下來了。
拆卸(xie)(xie)并清洗(xi)軸(zhou)承(cheng)座:先輕輕松動一下(xia)軸(zhou)承(cheng)座后用拆卸(xie)(xie)螺(luo)栓頂起軸(zhou)承(cheng)座,并且沿(yan)著泵(beng)軸(zhou)往上(shang)提而(er)卸(xie)(xie)下(xia),再(zai)用噴氣燃料清洗(xi)軸(zhou)承(cheng)及座,裝前(qian)晾干并涂抹少許(xu)20號機械油用來潤滑保護(hu)。
拆密(mi)封座:擰下(xia)密(mi)封座壓緊螺母,輕輕卸(xie)下(xia)密(mi)封座并清洗。
通河機械密封裝配:在(zai)動、靜(jing)環(huan)鏡面上(shang)涂一層(ceng)潔凈的20號潤(run)滑油(you),導(dao)軸(zhou)承座也抹(mo)上(shang)潤(run)滑油(you),先把(ba)靜(jing)環(huan)輕輕定位(wei)裝入導(dao)軸(zhou)承座,再在(zai)泵軸(zhou)上(shang)抹(mo)上(shang)潤(run)滑油(you),把(ba)動環(huan)部分(fen)輕輕裝入泵軸(zhou)上(shang),用手輕推密封環(huan)應能伸縮自如,注意動、靜(jing)環(huan)部分(fen)的防轉部位(wei)需(xu)裝配到位(wei)。
裝(zhuang)聯(lian)(lian)軸(zhou)(zhou)(zhou)器:在電機軸(zhou)(zhou)(zhou)頭上(shang)(shang)裝(zhuang)上(shang)(shang)擋(dang)圈(quan),裝(zhuang)上(shang)(shang)一半(ban)(ban)聯(lian)(lian)軸(zhou)(zhou)(zhou)器,再(zai)在泵軸(zhou)(zhou)(zhou)端和聯(lian)(lian)軸(zhou)(zhou)(zhou)器槽(cao)內(nei)裝(zhuang)上(shang)(shang)擋(dang)塊并用(yong)梅花扳(ban)手擰(ning)緊(jin)螺栓;再(zai)裝(zhuang)上(shang)(shang)另(ling)一半(ban)(ban)聯(lian)(lian)軸(zhou)(zhou)(zhou)器擰(ning)上(shang)(shang)內(nei)六(liu)角螺釘(ding)。安裝(zhuang)聯(lian)(lian)軸(zhou)(zhou)(zhou)器正確的檢(jian)查要求(qiu):對分式聯(lian)(lian)軸(zhou)(zhou)(zhou)器上(shang)(shang)下間(jian)隙需要均勻,用(yong)手盤(pan)動聯(lian)(lian)軸(zhou)(zhou)(zhou)器幾圈(quan)檢(jian)查轉動的靈活性。
裝密(mi)封(feng)座:先將(jiang)密(mi)封(feng)座裝入橡膠油封(feng),再把密(mi)封(feng)座裝入泵蓋(gai)(gai)并(bing)壓在(zai)軸(zhou)承座上(shang),擰緊螺(luo)(luo)母,確保所(suo)有(you)安裝螺(luo)(luo)釘(ding)(ding)緊固。當安裝螺(luo)(luo)釘(ding)(ding)被用作(zuo)密(mi)封(feng)與軸(zhou)之間(jian)(jian)的(de)(de)驅動時(shi),軸(zhou)應打埋(mai)頭孔來加(jia)固連(lian)接,緊固壓蓋(gai)(gai)螺(luo)(luo)栓時(shi)應該(gai)平穩緊固,并(bing)且(qie)不要使壓蓋(gai)(gai)受彈力。在(zai)可能(neng)的(de)(de)地(di)方使用4個(ge)以上(shang)螺(luo)(luo)釘(ding)(ding)的(de)(de)等間(jian)(jian)距壓蓋(gai)(gai),緊固壓蓋(gai)(gai)螺(luo)(luo)栓時(shi),用塞尺(chi)檢查軸(zhou)與壓蓋(gai)(gai)之間(jian)(jian)的(de)(de)間(jian)(jian)隙,這(zhe)在(zai)密(mi)封(feng)腔對(dui)壓蓋(gai)(gai)不導向時(shi),顯得特(te)別重(zhong)要,因為(wei)壓蓋(gai)(gai)必須對(dui)中。
