神池機械密封利用(yong)(yong)(yong)機械方式傳(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)力和運動(dong)(dong)的傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong),機械傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)在機械工程中應(ying)用(yong)(yong)(yong)非常廣(guang)泛(fan),有(you)多種形式,主要包(bao)括皮(pi)帶傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)、齒(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)、蝸桿蝸輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)、齒(chi)輪(lun)齒(chi)條傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)和螺旋傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)等(deng)。齒(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)能夠用(yong)(yong)(yong)于大功率的場合(he),傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)比準確,但一般(ban)要求(qiu)較高的制造精度和安裝精度。還有(you)一類是靠機件間(jian)的摩擦力傳(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)力和運動(dong)(dong)的摩擦傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong),包(bao)括帶傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)和摩擦輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)等(deng)。摩擦傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)容易實現(xian)無(wu)級變速,可以適應(ying)軸間(jian)距較大的傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)場合(he),而過載(zai)打滑還能起到緩沖和保護(hu)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)裝置的作用(yong)(yong)(yong),但這種傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)一般(ban)不(bu)能用(yong)(yong)(yong)于大功率的場合(he),也(ye)不(bu)能保證(zheng)準確的傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)比。
傳動形式多,但是神池機械密封的更換工作大(da)同小(xiao)異,首先拆(chai)前需確認電(dian)機處于檢修(xiu)狀(zhuang)態,擰下加油螺塞,用(yong)吸管(guan)把密封座(zuo)腔內的潤滑油吸出。準(zhun)備好(hao)放置泵(beng)零件的工作臺及(ji)拆(chai)裝工具,切勿任意亂放亂用(yong),避(bi)免(mian)碰壞泵(beng)的零部件。
拆對分式(shi)聯軸(zhou)(zhou)(zhou)器:先把聯軸(zhou)(zhou)(zhou)器的固(gu)定內六角螺釘擰下(xia)(xia)來,再輕輕把聯軸(zhou)(zhou)(zhou)器的一半從軸(zhou)(zhou)(zhou)上慢慢拉下(xia)(xia),注意不要掉了,再用梅(mei)花扳手擰下(xia)(xia)泵軸(zhou)(zhou)(zhou)吊緊螺栓(shuan)和擋塊(kuai),讓(rang)葉輪慢慢下(xia)(xia)沉至(zhi)泵體,然后(hou)拆下(xia)(xia)另外一半聯軸(zhou)(zhou)(zhou)器,拿(na)下(xia)(xia)泵軸(zhou)(zhou)(zhou)擋圈。
拆卸神池機械密封:抓(zhua)住密(mi)封彈簧順(shun)著泵軸(zhou)往上(shang)提,就(jiu)能拆下來(lai)了。
拆卸并清洗軸(zhou)承座:先輕輕松(song)動一下軸(zhou)承座后用拆卸螺栓頂起軸(zhou)承座,并且沿著泵軸(zhou)往上提而(er)卸下,再(zai)用噴(pen)氣(qi)燃料清洗軸(zhou)承及座,裝前晾干并涂抹(mo)少許(xu)20號機械(xie)油(you)用來潤滑(hua)保護(hu)。
拆密(mi)封(feng)座:擰下密(mi)封(feng)座壓緊螺母,輕(qing)輕(qing)卸下密(mi)封(feng)座并清洗。
神池機械密封裝(zhuang)(zhuang)配:在動(dong)、靜(jing)環(huan)鏡(jing)面上(shang)涂一層潔凈的20號潤(run)滑(hua)油,導(dao)軸承(cheng)座也抹上(shang)潤(run)滑(hua)油,先把(ba)靜(jing)環(huan)輕(qing)輕(qing)定(ding)位(wei)(wei)裝(zhuang)(zhuang)入導(dao)軸承(cheng)座,再(zai)在泵軸上(shang)抹上(shang)潤(run)滑(hua)油,把(ba)動(dong)環(huan)部分(fen)輕(qing)輕(qing)裝(zhuang)(zhuang)入泵軸上(shang),用手輕(qing)推密(mi)封(feng)環(huan)應能伸(shen)縮自如(ru),注意動(dong)、靜(jing)環(huan)部分(fen)的防轉部位(wei)(wei)需裝(zhuang)(zhuang)配到位(wei)(wei)。
裝聯(lian)(lian)(lian)(lian)軸(zhou)器(qi)(qi):在(zai)電機軸(zhou)頭上(shang)(shang)裝上(shang)(shang)擋圈,裝上(shang)(shang)一半(ban)聯(lian)(lian)(lian)(lian)軸(zhou)器(qi)(qi),再在(zai)泵軸(zhou)端和聯(lian)(lian)(lian)(lian)軸(zhou)器(qi)(qi)槽內裝上(shang)(shang)擋塊并用梅花扳手擰緊螺栓;再裝上(shang)(shang)另一半(ban)聯(lian)(lian)(lian)(lian)軸(zhou)器(qi)(qi)擰上(shang)(shang)內六角螺釘。安裝聯(lian)(lian)(lian)(lian)軸(zhou)器(qi)(qi)正(zheng)確的檢查要(yao)求:對分式(shi)聯(lian)(lian)(lian)(lian)軸(zhou)器(qi)(qi)上(shang)(shang)下間隙需(xu)要(yao)均勻,用手盤動聯(lian)(lian)(lian)(lian)軸(zhou)器(qi)(qi)幾圈檢查轉動的靈活性(xing)。
裝密(mi)封座:先將密(mi)封座裝入(ru)橡膠(jiao)油(you)封,再把(ba)密(mi)封座裝入(ru)泵蓋(gai)(gai)(gai)并(bing)壓(ya)(ya)(ya)(ya)在(zai)軸(zhou)承座上(shang)(shang),擰緊(jin)螺(luo)(luo)(luo)母(mu),確保(bao)所有(you)安裝螺(luo)(luo)(luo)釘緊(jin)固(gu)。當安裝螺(luo)(luo)(luo)釘被用作(zuo)密(mi)封與軸(zhou)之(zhi)間(jian)(jian)(jian)的(de)(de)驅動時(shi),軸(zhou)應(ying)打(da)埋頭孔來加(jia)固(gu)連接(jie),緊(jin)固(gu)壓(ya)(ya)(ya)(ya)蓋(gai)(gai)(gai)螺(luo)(luo)(luo)栓時(shi)應(ying)該平穩緊(jin)固(gu),并(bing)且(qie)不要使(shi)壓(ya)(ya)(ya)(ya)蓋(gai)(gai)(gai)受(shou)彈(dan)力。在(zai)可能的(de)(de)地方使(shi)用4個以上(shang)(shang)螺(luo)(luo)(luo)釘的(de)(de)等間(jian)(jian)(jian)距壓(ya)(ya)(ya)(ya)蓋(gai)(gai)(gai),緊(jin)固(gu)壓(ya)(ya)(ya)(ya)蓋(gai)(gai)(gai)螺(luo)(luo)(luo)栓時(shi),用塞尺檢查軸(zhou)與壓(ya)(ya)(ya)(ya)蓋(gai)(gai)(gai)之(zhi)間(jian)(jian)(jian)的(de)(de)間(jian)(jian)(jian)隙,這在(zai)密(mi)封腔對壓(ya)(ya)(ya)(ya)蓋(gai)(gai)(gai)不導向(xiang)時(shi),顯得特別重要,因(yin)為壓(ya)(ya)(ya)(ya)蓋(gai)(gai)(gai)必須對中。
