發(fa)布(bu)時間:2021-06-01 15:17:49 人氣:183184 來(lai)源(yuan):川工(gong)密封
堆龍德慶機械密封利用(yong)機(ji)械方式傳(chuan)遞(di)動(dong)(dong)(dong)力(li)和(he)運動(dong)(dong)(dong)的(de)(de)傳(chuan)動(dong)(dong)(dong),機(ji)械傳(chuan)動(dong)(dong)(dong)在機(ji)械工程中(zhong)應(ying)用(yong)非常廣泛,有多種形式,主要包括皮帶傳(chuan)動(dong)(dong)(dong)、齒輪傳(chuan)動(dong)(dong)(dong)、鏈傳(chuan)動(dong)(dong)(dong)、蝸桿(gan)蝸輪傳(chuan)動(dong)(dong)(dong)、齒輪齒條傳(chuan)動(dong)(dong)(dong)和(he)螺旋(xuan)傳(chuan)動(dong)(dong)(dong)等。齒輪傳(chuan)動(dong)(dong)(dong)能(neng)夠用(yong)于大(da)功(gong)率的(de)(de)場(chang)合,傳(chuan)動(dong)(dong)(dong)比準確,但(dan)一般要求(qiu)較高的(de)(de)制(zhi)造精度和(he)安(an)裝精度。還有一類是靠機(ji)件間(jian)的(de)(de)摩擦力(li)傳(chuan)遞(di)動(dong)(dong)(dong)力(li)和(he)運動(dong)(dong)(dong)的(de)(de)摩擦傳(chuan)動(dong)(dong)(dong),包括帶傳(chuan)動(dong)(dong)(dong)、繩傳(chuan)動(dong)(dong)(dong)和(he)摩擦輪傳(chuan)動(dong)(dong)(dong)等。摩擦傳(chuan)動(dong)(dong)(dong)容(rong)易實現無級變(bian)速,可以(yi)適應(ying)軸間(jian)距較大(da)的(de)(de)傳(chuan)動(dong)(dong)(dong)場(chang)合,而過載打滑(hua)還能(neng)起到緩沖(chong)和(he)保(bao)護傳(chuan)動(dong)(dong)(dong)裝置的(de)(de)作用(yong),但(dan)這種傳(chuan)動(dong)(dong)(dong)一般不能(neng)用(yong)于大(da)功(gong)率的(de)(de)場(chang)合,也(ye)不能(neng)保(bao)證準確的(de)(de)傳(chuan)動(dong)(dong)(dong)比。
傳動形式多,但是堆龍德慶機械密封的更(geng)換工作大(da)同(tong)小異(yi),首(shou)先拆(chai)(chai)前(qian)需確(que)認電機處于檢修(xiu)狀(zhuang)態,擰下加油(you)螺塞,用吸管(guan)把密封座(zuo)腔內(nei)的潤滑油(you)吸出(chu)。準備好放置泵(beng)零件的工作臺(tai)及拆(chai)(chai)裝(zhuang)工具,切(qie)勿任意亂放亂用,避(bi)免碰壞泵(beng)的零部件。
拆對分式(shi)聯軸器:先把聯軸器的(de)固定內六(liu)角螺釘擰下(xia)來,再輕輕把聯軸器的(de)一半從軸上慢(man)慢(man)拉下(xia),注意不(bu)要(yao)掉了,再用(yong)梅花扳手擰下(xia)泵(beng)(beng)軸吊緊螺栓和擋塊,讓葉輪(lun)慢(man)慢(man)下(xia)沉至泵(beng)(beng)體,然后拆下(xia)另(ling)外一半聯軸器,拿下(xia)泵(beng)(beng)軸擋圈(quan)。
拆卸堆龍德慶機械密封:抓住密封彈簧(huang)順(shun)著泵軸往上提,就(jiu)能拆下(xia)來了。
拆卸并清洗軸(zhou)承座(zuo)(zuo)(zuo):先輕(qing)輕(qing)松(song)動一下軸(zhou)承座(zuo)(zuo)(zuo)后用拆卸螺栓頂起(qi)軸(zhou)承座(zuo)(zuo)(zuo),并且(qie)沿著泵軸(zhou)往(wang)上提(ti)而卸下,再用噴氣燃料清洗軸(zhou)承及座(zuo)(zuo)(zuo),裝前晾干并涂抹少許20號機械油用來(lai)潤滑(hua)保護。
拆密封(feng)座(zuo):擰下密封(feng)座(zuo)壓(ya)緊螺母,輕(qing)輕(qing)卸(xie)下密封(feng)座(zuo)并(bing)清(qing)洗。
堆龍德慶機械密封裝(zhuang)配(pei):在(zai)動、靜(jing)環(huan)鏡面上(shang)涂一層潔凈的20號潤(run)滑油(you),導軸(zhou)承座也抹上(shang)潤(run)滑油(you),先把靜(jing)環(huan)輕(qing)輕(qing)定位(wei)裝(zhuang)入導軸(zhou)承座,再在(zai)泵軸(zhou)上(shang)抹上(shang)潤(run)滑油(you),把動環(huan)部分(fen)輕(qing)輕(qing)裝(zhuang)入泵軸(zhou)上(shang),用手輕(qing)推密封環(huan)應能伸縮自如(ru),注意動、靜(jing)環(huan)部分(fen)的防(fang)轉部位(wei)需裝(zhuang)配(pei)到位(wei)。
裝(zhuang)(zhuang)(zhuang)(zhuang)聯(lian)軸器(qi):在電機(ji)軸頭上(shang)(shang)(shang)裝(zhuang)(zhuang)(zhuang)(zhuang)上(shang)(shang)(shang)擋(dang)圈(quan),裝(zhuang)(zhuang)(zhuang)(zhuang)上(shang)(shang)(shang)一半聯(lian)軸器(qi),再在泵軸端和(he)聯(lian)軸器(qi)槽內裝(zhuang)(zhuang)(zhuang)(zhuang)上(shang)(shang)(shang)擋(dang)塊并用梅花扳手擰(ning)緊螺栓;再裝(zhuang)(zhuang)(zhuang)(zhuang)上(shang)(shang)(shang)另一半聯(lian)軸器(qi)擰(ning)上(shang)(shang)(shang)內六角(jiao)螺釘。安裝(zhuang)(zhuang)(zhuang)(zhuang)聯(lian)軸器(qi)正確的檢查要求:對(dui)分式聯(lian)軸器(qi)上(shang)(shang)(shang)下間隙(xi)需要均勻,用手盤動聯(lian)軸器(qi)幾圈(quan)檢查轉動的靈(ling)活性。
裝(zhuang)密(mi)封(feng)座(zuo):先將密(mi)封(feng)座(zuo)裝(zhuang)入橡膠油封(feng),再把(ba)密(mi)封(feng)座(zuo)裝(zhuang)入泵蓋并(bing)壓(ya)(ya)在(zai)軸(zhou)承座(zuo)上,擰緊(jin)(jin)(jin)螺(luo)母(mu),確保所有安裝(zhuang)螺(luo)釘緊(jin)(jin)(jin)固(gu)(gu)。當安裝(zhuang)螺(luo)釘被用(yong)作密(mi)封(feng)與軸(zhou)之(zhi)間(jian)的(de)驅(qu)動時,軸(zhou)應打埋頭孔來加(jia)固(gu)(gu)連(lian)接(jie),緊(jin)(jin)(jin)固(gu)(gu)壓(ya)(ya)蓋螺(luo)栓(shuan)時應該平(ping)穩緊(jin)(jin)(jin)固(gu)(gu),并(bing)且不要(yao)使(shi)(shi)壓(ya)(ya)蓋受彈力。在(zai)可能的(de)地方使(shi)(shi)用(yong)4個以上螺(luo)釘的(de)等間(jian)距壓(ya)(ya)蓋,緊(jin)(jin)(jin)固(gu)(gu)壓(ya)(ya)蓋螺(luo)栓(shuan)時,用(yong)塞尺檢查(cha)軸(zhou)與壓(ya)(ya)蓋之(zhi)間(jian)的(de)間(jian)隙,這在(zai)密(mi)封(feng)腔對(dui)壓(ya)(ya)蓋不導向時,顯得特別重要(yao),因為(wei)壓(ya)(ya)蓋必須(xu)對(dui)中。
