池州機械密封利用機(ji)械(xie)方式傳(chuan)遞動(dong)(dong)(dong)力和運動(dong)(dong)(dong)的(de)(de)(de)傳(chuan)動(dong)(dong)(dong),機(ji)械(xie)傳(chuan)動(dong)(dong)(dong)在(zai)機(ji)械(xie)工程(cheng)中應用非常(chang)廣泛,有(you)(you)多種(zhong)形式,主(zhu)要包括皮帶傳(chuan)動(dong)(dong)(dong)、齒(chi)輪(lun)傳(chuan)動(dong)(dong)(dong)、鏈傳(chuan)動(dong)(dong)(dong)、蝸桿(gan)蝸輪(lun)傳(chuan)動(dong)(dong)(dong)、齒(chi)輪(lun)齒(chi)條傳(chuan)動(dong)(dong)(dong)和螺旋傳(chuan)動(dong)(dong)(dong)等。齒(chi)輪(lun)傳(chuan)動(dong)(dong)(dong)能(neng)夠用于大功率的(de)(de)(de)場合(he),傳(chuan)動(dong)(dong)(dong)比準(zhun)確,但(dan)一般要求較高的(de)(de)(de)制造精度(du)和安裝精度(du)。還(huan)有(you)(you)一類是靠機(ji)件間的(de)(de)(de)摩擦(ca)(ca)力傳(chuan)遞動(dong)(dong)(dong)力和運動(dong)(dong)(dong)的(de)(de)(de)摩擦(ca)(ca)傳(chuan)動(dong)(dong)(dong),包括帶傳(chuan)動(dong)(dong)(dong)、繩傳(chuan)動(dong)(dong)(dong)和摩擦(ca)(ca)輪(lun)傳(chuan)動(dong)(dong)(dong)等。摩擦(ca)(ca)傳(chuan)動(dong)(dong)(dong)容易(yi)實現(xian)無級變速,可(ke)以適(shi)應軸間距較大的(de)(de)(de)傳(chuan)動(dong)(dong)(dong)場合(he),而(er)過載打滑還(huan)能(neng)起到(dao)緩沖和保護傳(chuan)動(dong)(dong)(dong)裝置的(de)(de)(de)作用,但(dan)這種(zhong)傳(chuan)動(dong)(dong)(dong)一般不能(neng)用于大功率的(de)(de)(de)場合(he),也(ye)不能(neng)保證準(zhun)確的(de)(de)(de)傳(chuan)動(dong)(dong)(dong)比。
傳動形式多,但是池州機械密封的(de)更換工(gong)作(zuo)大同小異,首(shou)先拆前需確認電機處于檢修狀態,擰下加油(you)螺(luo)塞(sai),用吸管把密封(feng)座腔(qiang)內的(de)潤滑(hua)油(you)吸出。準備好(hao)放(fang)置泵(beng)零(ling)件的(de)工(gong)作(zuo)臺及拆裝工(gong)具(ju),切勿任(ren)意亂放(fang)亂用,避免碰壞泵(beng)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)的固定內六角螺釘擰下(xia)(xia)來,再輕輕把聯軸(zhou)(zhou)器(qi)的一半(ban)(ban)從軸(zhou)(zhou)上慢(man)慢(man)拉下(xia)(xia),注意(yi)不(bu)要掉了,再用(yong)梅花扳手擰下(xia)(xia)泵軸(zhou)(zhou)吊(diao)緊螺栓和擋塊,讓葉(xie)輪慢(man)慢(man)下(xia)(xia)沉至泵體,然后拆(chai)下(xia)(xia)另外一半(ban)(ban)聯軸(zhou)(zhou)器(qi),拿下(xia)(xia)泵軸(zhou)(zhou)擋圈。
拆卸池州機械密封:抓住密封彈簧順著泵軸往上(shang)提,就能拆下來(lai)了。
拆(chai)卸(xie)并(bing)清洗軸(zhou)承(cheng)(cheng)座(zuo):先(xian)輕輕松動一下(xia)軸(zhou)承(cheng)(cheng)座(zuo)后(hou)用拆(chai)卸(xie)螺栓頂起軸(zhou)承(cheng)(cheng)座(zuo),并(bing)且沿著泵(beng)軸(zhou)往上提而卸(xie)下(xia),再用噴氣燃(ran)料(liao)清洗軸(zhou)承(cheng)(cheng)及座(zuo),裝前晾干(gan)并(bing)涂(tu)抹少許20號機械油(you)用來潤滑(hua)保(bao)護。
拆密封座:擰下密封座壓(ya)緊螺母,輕(qing)輕(qing)卸下密封座并清洗。
池州機械密封裝(zhuang)(zhuang)配(pei):在(zai)動(dong)(dong)、靜環(huan)(huan)鏡(jing)面上(shang)(shang)(shang)涂一(yi)層潔凈的20號潤(run)滑油,導軸承座(zuo)(zuo)也抹上(shang)(shang)(shang)潤(run)滑油,先(xian)把(ba)靜環(huan)(huan)輕輕定位(wei)(wei)裝(zhuang)(zhuang)入導軸承座(zuo)(zuo),再在(zai)泵軸上(shang)(shang)(shang)抹上(shang)(shang)(shang)潤(run)滑油,把(ba)動(dong)(dong)環(huan)(huan)部分(fen)輕輕裝(zhuang)(zhuang)入泵軸上(shang)(shang)(shang),用(yong)手輕推密(mi)封環(huan)(huan)應(ying)能(neng)伸(shen)縮自如,注意動(dong)(dong)、靜環(huan)(huan)部分(fen)的防轉部位(wei)(wei)需裝(zhuang)(zhuang)配(pei)到位(wei)(wei)。
裝(zhuang)聯(lian)軸器(qi)(qi):在電(dian)機(ji)軸頭上(shang)裝(zhuang)上(shang)擋圈,裝(zhuang)上(shang)一半聯(lian)軸器(qi)(qi),再(zai)在泵(beng)軸端(duan)和聯(lian)軸器(qi)(qi)槽內裝(zhuang)上(shang)擋塊并用(yong)梅(mei)花扳(ban)手擰(ning)緊螺(luo)栓(shuan);再(zai)裝(zhuang)上(shang)另一半聯(lian)軸器(qi)(qi)擰(ning)上(shang)內六角螺(luo)釘(ding)。安裝(zhuang)聯(lian)軸器(qi)(qi)正確的檢(jian)查要(yao)求:對分式(shi)聯(lian)軸器(qi)(qi)上(shang)下間(jian)隙需(xu)要(yao)均(jun)勻,用(yong)手盤動聯(lian)軸器(qi)(qi)幾圈檢(jian)查轉動的靈活性。
裝(zhuang)(zhuang)(zhuang)密(mi)封(feng)座(zuo):先(xian)將密(mi)封(feng)座(zuo)裝(zhuang)(zhuang)(zhuang)入橡膠油封(feng),再把(ba)密(mi)封(feng)座(zuo)裝(zhuang)(zhuang)(zhuang)入泵蓋并(bing)壓(ya)在軸(zhou)承座(zuo)上,擰(ning)緊螺(luo)母,確保所有安裝(zhuang)(zhuang)(zhuang)螺(luo)釘(ding)緊固(gu)(gu)。當安裝(zhuang)(zhuang)(zhuang)螺(luo)釘(ding)被用作(zuo)密(mi)封(feng)與(yu)(yu)軸(zhou)之(zhi)間(jian)的(de)驅(qu)動時,軸(zhou)應打埋頭孔來加固(gu)(gu)連接(jie),緊固(gu)(gu)壓(ya)蓋螺(luo)栓時應該平穩緊固(gu)(gu),并(bing)且不要使壓(ya)蓋受彈力。在可能的(de)地方使用4個以上螺(luo)釘(ding)的(de)等間(jian)距壓(ya)蓋,緊固(gu)(gu)壓(ya)蓋螺(luo)栓時,用塞(sai)尺檢查軸(zhou)與(yu)(yu)壓(ya)蓋之(zhi)間(jian)的(de)間(jian)隙,這在密(mi)封(feng)腔(qiang)對壓(ya)蓋不導向時,顯得(de)特別重要,因(yin)為壓(ya)蓋必須(xu)對中。
