曲松機械密封利用機(ji)械方式傳(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)力(li)(li)和(he)(he)運動(dong)(dong)(dong)的(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong),機(ji)械傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)在(zai)機(ji)械工程(cheng)中應用非常廣泛,有多種(zhong)形式,主要包(bao)括(kuo)(kuo)皮帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)、齒(chi)輪(lun)(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)、蝸(gua)桿蝸(gua)輪(lun)(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)、齒(chi)輪(lun)(lun)齒(chi)條傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)和(he)(he)螺旋(xuan)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)等。齒(chi)輪(lun)(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)能夠(gou)用于大(da)功率(lv)的(de)(de)場(chang)合(he),傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)比準確,但一般(ban)要求較高的(de)(de)制(zhi)造精度和(he)(he)安裝(zhuang)精度。還(huan)有一類是靠機(ji)件間(jian)的(de)(de)摩(mo)(mo)(mo)擦(ca)力(li)(li)傳(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)力(li)(li)和(he)(he)運動(dong)(dong)(dong)的(de)(de)摩(mo)(mo)(mo)擦(ca)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong),包(bao)括(kuo)(kuo)帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)、繩(sheng)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)和(he)(he)摩(mo)(mo)(mo)擦(ca)輪(lun)(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)等。摩(mo)(mo)(mo)擦(ca)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)容易實現無級變(bian)速(su),可以適(shi)應軸(zhou)間(jian)距較大(da)的(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)場(chang)合(he),而過載打滑還(huan)能起到緩沖和(he)(he)保(bao)護傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)裝(zhuang)置(zhi)的(de)(de)作用,但這(zhe)種(zhong)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)一般(ban)不能用于大(da)功率(lv)的(de)(de)場(chang)合(he),也不能保(bao)證準確的(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)比。
傳動形式多,但是曲松機械密封的更換工(gong)作大同小異,首先拆(chai)前需確認(ren)電機處于(yu)檢修狀態,擰下加油(you)螺塞,用吸管把(ba)密封座腔內的潤滑油(you)吸出。準備好(hao)放置(zhi)泵零件(jian)的工(gong)作臺及拆(chai)裝(zhuang)工(gong)具(ju),切(qie)勿(wu)任意(yi)亂放亂用,避(bi)免碰壞泵的零部件(jian)。
拆對(dui)分(fen)式聯(lian)軸器:先把聯(lian)軸器的固定內六角螺釘擰下(xia)(xia)來,再(zai)輕輕把聯(lian)軸器的一半從軸上慢慢拉(la)下(xia)(xia),注意不要(yao)掉了(le),再(zai)用(yong)梅花扳手擰下(xia)(xia)泵(beng)軸吊緊螺栓和擋塊,讓葉輪慢慢下(xia)(xia)沉至(zhi)泵(beng)體,然后拆下(xia)(xia)另(ling)外一半聯(lian)軸器,拿下(xia)(xia)泵(beng)軸擋圈。
拆卸曲松機械密封:抓住密封彈簧(huang)順著泵軸往上(shang)提,就能拆(chai)下(xia)來了。
拆(chai)卸(xie)(xie)并清洗軸承座(zuo):先輕(qing)(qing)輕(qing)(qing)松動一下軸承座(zuo)后用拆(chai)卸(xie)(xie)螺栓頂起軸承座(zuo),并且沿著泵(beng)軸往(wang)上(shang)提而卸(xie)(xie)下,再用噴氣燃料清洗軸承及座(zuo),裝前晾(liang)干(gan)并涂抹(mo)少(shao)許20號機械油(you)用來(lai)潤滑保護。
拆密(mi)封座:擰下密(mi)封座壓(ya)緊(jin)螺母,輕(qing)輕(qing)卸下密(mi)封座并清洗(xi)。
曲松機械密封裝配(pei):在(zai)動(dong)(dong)、靜(jing)環鏡面(mian)上涂一層潔凈的(de)20號(hao)潤滑油,導軸(zhou)(zhou)承(cheng)座也抹上潤滑油,先把(ba)靜(jing)環輕(qing)輕(qing)定(ding)位裝入(ru)導軸(zhou)(zhou)承(cheng)座,再在(zai)泵軸(zhou)(zhou)上抹上潤滑油,把(ba)動(dong)(dong)環部(bu)分輕(qing)輕(qing)裝入(ru)泵軸(zhou)(zhou)上,用手輕(qing)推密封環應能伸縮自如,注(zhu)意動(dong)(dong)、靜(jing)環部(bu)分的(de)防(fang)轉部(bu)位需裝配(pei)到位。
裝(zhuang)(zhuang)(zhuang)聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi):在(zai)電機軸(zhou)(zhou)頭(tou)上(shang)裝(zhuang)(zhuang)(zhuang)上(shang)擋(dang)圈,裝(zhuang)(zhuang)(zhuang)上(shang)一(yi)半(ban)聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi),再(zai)在(zai)泵軸(zhou)(zhou)端和聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)槽內裝(zhuang)(zhuang)(zhuang)上(shang)擋(dang)塊并(bing)用梅花扳手擰緊(jin)螺栓;再(zai)裝(zhuang)(zhuang)(zhuang)上(shang)另一(yi)半(ban)聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)擰上(shang)內六角螺釘。安裝(zhuang)(zhuang)(zhuang)聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)正(zheng)確的(de)檢查要(yao)求:對分式聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)上(shang)下間隙需要(yao)均(jun)勻,用手盤(pan)動(dong)聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)幾圈檢查轉(zhuan)動(dong)的(de)靈活(huo)性(xing)。
裝(zhuang)(zhuang)密(mi)封(feng)座(zuo)(zuo):先將密(mi)封(feng)座(zuo)(zuo)裝(zhuang)(zhuang)入(ru)橡膠(jiao)油封(feng),再把密(mi)封(feng)座(zuo)(zuo)裝(zhuang)(zhuang)入(ru)泵蓋(gai)(gai)并壓(ya)(ya)(ya)在軸(zhou)承座(zuo)(zuo)上,擰(ning)緊(jin)螺母,確保所有(you)安裝(zhuang)(zhuang)螺釘(ding)(ding)緊(jin)固。當安裝(zhuang)(zhuang)螺釘(ding)(ding)被用作(zuo)密(mi)封(feng)與(yu)軸(zhou)之(zhi)間(jian)的驅動時,軸(zhou)應打埋頭孔來加(jia)固連接,緊(jin)固壓(ya)(ya)(ya)蓋(gai)(gai)螺栓時應該平(ping)穩緊(jin)固,并且不要(yao)使(shi)壓(ya)(ya)(ya)蓋(gai)(gai)受(shou)彈(dan)力。在可能的地(di)方使(shi)用4個以上螺釘(ding)(ding)的等間(jian)距壓(ya)(ya)(ya)蓋(gai)(gai),緊(jin)固壓(ya)(ya)(ya)蓋(gai)(gai)螺栓時,用塞(sai)尺檢查(cha)軸(zhou)與(yu)壓(ya)(ya)(ya)蓋(gai)(gai)之(zhi)間(jian)的間(jian)隙,這(zhe)在密(mi)封(feng)腔對壓(ya)(ya)(ya)蓋(gai)(gai)不導向時,顯得特別重(zhong)要(yao),因(yin)為(wei)壓(ya)(ya)(ya)蓋(gai)(gai)必(bi)須對中(zhong)。
