房縣機械密封利用(yong)機械方式傳(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)力(li)和(he)運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)的(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong),機械傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)在機械工程中應用(yong)非(fei)常廣泛,有多種(zhong)形式,主要(yao)包(bao)括皮帶(dai)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、齒輪(lun)(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、鏈(lian)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、蝸(gua)桿蝸(gua)輪(lun)(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、齒輪(lun)(lun)齒條傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)和(he)螺旋傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)等。齒輪(lun)(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)能夠(gou)用(yong)于大(da)功(gong)率的(de)場合(he)(he),傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)比準確,但(dan)一般要(yao)求較高(gao)的(de)制造精度(du)和(he)安裝精度(du)。還有一類是靠機件間的(de)摩(mo)擦力(li)傳(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)力(li)和(he)運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)的(de)摩(mo)擦傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong),包(bao)括帶(dai)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)和(he)摩(mo)擦輪(lun)(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)等。摩(mo)擦傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)容易實現(xian)無級變速,可以適應軸間距較大(da)的(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)場合(he)(he),而過載打滑還能起到緩沖和(he)保(bao)(bao)護傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)裝置的(de)作用(yong),但(dan)這種(zhong)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)一般不能用(yong)于大(da)功(gong)率的(de)場合(he)(he),也不能保(bao)(bao)證準確的(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)比。
傳動形式多,但是房縣機械密封的更換工作大同小異,首先拆前需確認電機處于檢修(xiu)狀(zhuang)態,擰下加油螺塞,用(yong)吸管把密封座(zuo)腔內的潤滑油吸出。準備(bei)好放(fang)置(zhi)泵零件的工作臺及拆裝工具,切勿任意(yi)亂(luan)放(fang)亂(luan)用(yong),避免(mian)碰壞泵的零部件。
拆(chai)對分式(shi)聯軸(zhou)器:先把聯軸(zhou)器的固定內六角螺釘(ding)擰(ning)下來,再輕輕把聯軸(zhou)器的一半從(cong)軸(zhou)上(shang)慢(man)慢(man)拉下,注意不要掉了,再用梅(mei)花(hua)扳手擰(ning)下泵軸(zhou)吊緊螺栓和擋(dang)塊,讓葉輪(lun)慢(man)慢(man)下沉至泵體,然后拆(chai)下另外一半聯軸(zhou)器,拿(na)下泵軸(zhou)擋(dang)圈。
拆卸房縣機械密封:抓住密封彈簧順(shun)著泵軸往(wang)上提,就能拆下(xia)來了。
拆卸(xie)并(bing)(bing)清洗(xi)(xi)軸(zhou)承(cheng)座:先輕(qing)輕(qing)松動一下(xia)軸(zhou)承(cheng)座后用拆卸(xie)螺栓頂起軸(zhou)承(cheng)座,并(bing)(bing)且(qie)沿著泵軸(zhou)往上提而卸(xie)下(xia),再用噴氣燃料(liao)清洗(xi)(xi)軸(zhou)承(cheng)及座,裝前晾干并(bing)(bing)涂抹少(shao)許20號機械油(you)用來潤滑保(bao)護。
拆密封(feng)座(zuo):擰下(xia)密封(feng)座(zuo)壓緊(jin)螺(luo)母,輕輕卸下(xia)密封(feng)座(zuo)并清洗。
房縣機械密封裝配:在動、靜(jing)環鏡面上涂一層(ceng)潔凈的20號潤滑油,導軸承座也抹上潤滑油,先(xian)把(ba)靜(jing)環輕(qing)(qing)輕(qing)(qing)定位(wei)(wei)裝入(ru)導軸承座,再在泵(beng)軸上抹上潤滑油,把(ba)動環部分(fen)輕(qing)(qing)輕(qing)(qing)裝入(ru)泵(beng)軸上,用(yong)手輕(qing)(qing)推密封環應能伸縮自(zi)如(ru),注意(yi)動、靜(jing)環部分(fen)的防轉(zhuan)部位(wei)(wei)需裝配到位(wei)(wei)。
裝(zhuang)聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)(qi):在電機軸(zhou)(zhou)(zhou)頭上(shang)裝(zhuang)上(shang)擋圈,裝(zhuang)上(shang)一(yi)半(ban)聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)(qi),再在泵(beng)軸(zhou)(zhou)(zhou)端和聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)槽內裝(zhuang)上(shang)擋塊并用(yong)梅花(hua)扳手擰緊螺栓;再裝(zhuang)上(shang)另一(yi)半(ban)聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)擰上(shang)內六(liu)角螺釘。安(an)裝(zhuang)聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)正確的檢(jian)查要求:對分式聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)上(shang)下間隙需要均(jun)勻,用(yong)手盤動聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)幾圈檢(jian)查轉(zhuan)動的靈活性。
裝密(mi)封(feng)(feng)座(zuo):先將密(mi)封(feng)(feng)座(zuo)裝入橡膠油封(feng)(feng),再把密(mi)封(feng)(feng)座(zuo)裝入泵蓋并壓(ya)(ya)在軸(zhou)承座(zuo)上(shang),擰緊螺(luo)(luo)(luo)(luo)母,確保所有安(an)裝螺(luo)(luo)(luo)(luo)釘(ding)緊固(gu)(gu)。當安(an)裝螺(luo)(luo)(luo)(luo)釘(ding)被用(yong)作密(mi)封(feng)(feng)與軸(zhou)之(zhi)(zhi)間的(de)(de)驅動時(shi),軸(zhou)應打埋頭孔來加(jia)固(gu)(gu)連接,緊固(gu)(gu)壓(ya)(ya)蓋螺(luo)(luo)(luo)(luo)栓時(shi)應該平穩緊固(gu)(gu),并且不(bu)要使壓(ya)(ya)蓋受彈力(li)。在可能的(de)(de)地方(fang)使用(yong)4個以上(shang)螺(luo)(luo)(luo)(luo)釘(ding)的(de)(de)等間距(ju)壓(ya)(ya)蓋,緊固(gu)(gu)壓(ya)(ya)蓋螺(luo)(luo)(luo)(luo)栓時(shi),用(yong)塞尺(chi)檢查軸(zhou)與壓(ya)(ya)蓋之(zhi)(zhi)間的(de)(de)間隙,這在密(mi)封(feng)(feng)腔(qiang)對壓(ya)(ya)蓋不(bu)導(dao)向時(shi),顯得特(te)別(bie)重要,因(yin)為壓(ya)(ya)蓋必須對中。
