呼圖壁機械密封利用(yong)(yong)(yong)(yong)機(ji)械(xie)方式傳(chuan)(chuan)(chuan)遞(di)動(dong)(dong)力和(he)(he)運動(dong)(dong)的(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong),機(ji)械(xie)傳(chuan)(chuan)(chuan)動(dong)(dong)在(zai)機(ji)械(xie)工程中(zhong)應(ying)用(yong)(yong)(yong)(yong)非常廣(guang)泛(fan),有(you)多種形式,主要包括皮帶傳(chuan)(chuan)(chuan)動(dong)(dong)、齒輪(lun)(lun)(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)、鏈(lian)傳(chuan)(chuan)(chuan)動(dong)(dong)、蝸桿蝸輪(lun)(lun)(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)、齒輪(lun)(lun)(lun)齒條傳(chuan)(chuan)(chuan)動(dong)(dong)和(he)(he)螺旋傳(chuan)(chuan)(chuan)動(dong)(dong)等(deng)。齒輪(lun)(lun)(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)能(neng)夠(gou)用(yong)(yong)(yong)(yong)于大(da)功(gong)率的(de)(de)場合(he),傳(chuan)(chuan)(chuan)動(dong)(dong)比準(zhun)確(que),但一般(ban)要求較(jiao)(jiao)高的(de)(de)制造精度和(he)(he)安裝精度。還有(you)一類是靠機(ji)件(jian)間(jian)的(de)(de)摩擦力傳(chuan)(chuan)(chuan)遞(di)動(dong)(dong)力和(he)(he)運動(dong)(dong)的(de)(de)摩擦傳(chuan)(chuan)(chuan)動(dong)(dong),包括帶傳(chuan)(chuan)(chuan)動(dong)(dong)、繩(sheng)傳(chuan)(chuan)(chuan)動(dong)(dong)和(he)(he)摩擦輪(lun)(lun)(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)等(deng)。摩擦傳(chuan)(chuan)(chuan)動(dong)(dong)容易實(shi)現無級變速,可以(yi)適應(ying)軸間(jian)距較(jiao)(jiao)大(da)的(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)場合(he),而(er)過載打滑(hua)還能(neng)起到緩沖和(he)(he)保護傳(chuan)(chuan)(chuan)動(dong)(dong)裝置的(de)(de)作用(yong)(yong)(yong)(yong),但這種傳(chuan)(chuan)(chuan)動(dong)(dong)一般(ban)不能(neng)用(yong)(yong)(yong)(yong)于大(da)功(gong)率的(de)(de)場合(he),也不能(neng)保證準(zhun)確(que)的(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)比。
傳動形式多,但是呼圖壁機械密封的(de)更換工作(zuo)大同小異(yi),首先(xian)拆前需(xu)確(que)認電機(ji)處于檢修狀(zhuang)態(tai),擰(ning)下加油螺塞(sai),用吸管把密封座腔內的(de)潤滑油吸出。準備好放置泵零(ling)件(jian)的(de)工作(zuo)臺及拆裝(zhuang)工具(ju),切勿任意亂放亂用,避(bi)免(mian)碰壞泵的(de)零(ling)部件(jian)。
拆對分式聯(lian)軸器:先(xian)把聯(lian)軸器的固定內六角螺(luo)釘擰(ning)下(xia)來,再輕(qing)輕(qing)把聯(lian)軸器的一(yi)半從軸上慢慢拉下(xia),注意不要掉(diao)了,再用梅花扳手(shou)擰(ning)下(xia)泵軸吊緊(jin)螺(luo)栓和(he)擋(dang)(dang)塊,讓葉輪慢慢下(xia)沉至泵體,然后拆下(xia)另外一(yi)半聯(lian)軸器,拿下(xia)泵軸擋(dang)(dang)圈(quan)。
拆卸呼圖壁機械密封:抓住密封彈簧順著泵(beng)軸(zhou)往上(shang)提,就(jiu)能拆(chai)下來了。
拆卸并(bing)清(qing)(qing)洗(xi)軸(zhou)(zhou)承座(zuo):先輕輕松動一下軸(zhou)(zhou)承座(zuo)后(hou)用拆卸螺(luo)栓頂起(qi)軸(zhou)(zhou)承座(zuo),并(bing)且(qie)沿著泵(beng)軸(zhou)(zhou)往上(shang)提(ti)而卸下,再用噴氣燃料清(qing)(qing)洗(xi)軸(zhou)(zhou)承及座(zuo),裝前晾干并(bing)涂抹少許20號機械油用來潤滑(hua)保(bao)護(hu)。
拆(chai)密封(feng)(feng)座:擰下密封(feng)(feng)座壓緊螺母(mu),輕(qing)輕(qing)卸下密封(feng)(feng)座并清(qing)洗。
呼圖壁機械密封裝配:在動(dong)、靜(jing)環(huan)鏡面(mian)上(shang)涂(tu)一層潔凈的20號潤(run)滑(hua)油,導(dao)軸(zhou)承座也抹上(shang)潤(run)滑(hua)油,先把(ba)靜(jing)環(huan)輕輕定(ding)位裝入導(dao)軸(zhou)承座,再(zai)在泵軸(zhou)上(shang)抹上(shang)潤(run)滑(hua)油,把(ba)動(dong)環(huan)部分(fen)輕輕裝入泵軸(zhou)上(shang),用手輕推密(mi)封環(huan)應能伸縮自(zi)如(ru),注意動(dong)、靜(jing)環(huan)部分(fen)的防轉(zhuan)部位需(xu)裝配到位。
裝(zhuang)聯(lian)軸(zhou)(zhou)器(qi):在電(dian)機(ji)軸(zhou)(zhou)頭上(shang)裝(zhuang)上(shang)擋圈,裝(zhuang)上(shang)一半(ban)聯(lian)軸(zhou)(zhou)器(qi),再在泵軸(zhou)(zhou)端和聯(lian)軸(zhou)(zhou)器(qi)槽內裝(zhuang)上(shang)擋塊并用梅花扳(ban)手擰緊螺栓(shuan);再裝(zhuang)上(shang)另(ling)一半(ban)聯(lian)軸(zhou)(zhou)器(qi)擰上(shang)內六角螺釘。安裝(zhuang)聯(lian)軸(zhou)(zhou)器(qi)正確的檢查(cha)(cha)要求:對分式聯(lian)軸(zhou)(zhou)器(qi)上(shang)下(xia)間隙需要均勻,用手盤動聯(lian)軸(zhou)(zhou)器(qi)幾(ji)圈檢查(cha)(cha)轉動的靈活(huo)性。
裝密封座:先將密封座裝入橡膠油封,再把密封座裝入泵蓋(gai)(gai)(gai)并壓(ya)(ya)(ya)在軸承座上(shang),擰緊螺(luo)母,確(que)保(bao)所有(you)安裝螺(luo)釘緊固(gu)。當安裝螺(luo)釘被用作密封與軸之間(jian)的驅(qu)動時,軸應打埋頭(tou)孔(kong)來加固(gu)連接,緊固(gu)壓(ya)(ya)(ya)蓋(gai)(gai)(gai)螺(luo)栓(shuan)(shuan)時應該平穩緊固(gu),并且不要(yao)使壓(ya)(ya)(ya)蓋(gai)(gai)(gai)受彈力。在可(ke)能的地(di)方(fang)使用4個以上(shang)螺(luo)釘的等間(jian)距壓(ya)(ya)(ya)蓋(gai)(gai)(gai),緊固(gu)壓(ya)(ya)(ya)蓋(gai)(gai)(gai)螺(luo)栓(shuan)(shuan)時,用塞(sai)尺檢查軸與壓(ya)(ya)(ya)蓋(gai)(gai)(gai)之間(jian)的間(jian)隙(xi),這在密封腔(qiang)對壓(ya)(ya)(ya)蓋(gai)(gai)(gai)不導向時,顯(xian)得特別重要(yao),因為壓(ya)(ya)(ya)蓋(gai)(gai)(gai)必須對中。
