河曲機械密封利用(yong)(yong)(yong)機械方式傳(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)力(li)(li)和運動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)的(de)(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)(yong)(yong)非常廣泛,有多種形(xing)式,主要包(bao)括皮帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、蝸桿(gan)蝸輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)齒(chi)條傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)和螺旋(xuan)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)等(deng)。齒(chi)輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)能夠用(yong)(yong)(yong)于(yu)(yu)大功(gong)(gong)率的(de)(de)場合,傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)比(bi)準(zhun)(zhun)確,但(dan)一般要求較(jiao)高的(de)(de)制(zhi)造精度和安裝(zhuang)精度。還有一類是(shi)靠機件間的(de)(de)摩(mo)(mo)(mo)擦力(li)(li)傳(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)力(li)(li)和運動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)的(de)(de)摩(mo)(mo)(mo)擦傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong),包(bao)括帶傳(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)和摩(mo)(mo)(mo)擦輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)等(deng)。摩(mo)(mo)(mo)擦傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)容易(yi)實現無級變速(su),可以(yi)適應軸間距較(jiao)大的(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)場合,而過載打滑還能起到(dao)緩沖(chong)和保護傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)裝(zhuang)置的(de)(de)作用(yong)(yong)(yong),但(dan)這種傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)一般不(bu)能用(yong)(yong)(yong)于(yu)(yu)大功(gong)(gong)率的(de)(de)場合,也不(bu)能保證(zheng)準(zhun)(zhun)確的(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)比(bi)。
傳動形式多,但是河曲機械密封的(de)更(geng)換工作大同小異,首先(xian)拆前需確認電(dian)機處于檢(jian)修狀態,擰下加油螺塞,用吸管把密封座腔內的(de)潤滑油吸出。準備好放置(zhi)泵零件(jian)的(de)工作臺及拆裝工具,切勿任(ren)意亂放亂用,避免碰(peng)壞泵的(de)零部件(jian)。
拆對(dui)分式聯(lian)(lian)軸(zhou)器(qi)(qi)(qi):先把聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)的固定內六角螺釘擰(ning)下(xia)來,再(zai)輕輕把聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)的一半(ban)從軸(zhou)上慢(man)慢(man)拉(la)下(xia),注(zhu)意(yi)不要掉了,再(zai)用梅花扳手擰(ning)下(xia)泵(beng)軸(zhou)吊緊螺栓(shuan)和(he)擋塊,讓葉輪慢(man)慢(man)下(xia)沉至泵(beng)體,然后拆下(xia)另外(wai)一半(ban)聯(lian)(lian)軸(zhou)器(qi)(qi)(qi),拿下(xia)泵(beng)軸(zhou)擋圈。
拆卸河曲機械密封:抓(zhua)住密封彈簧順著泵軸(zhou)往上提(ti),就能拆下來了(le)。
拆卸并(bing)(bing)清(qing)洗(xi)軸(zhou)(zhou)承(cheng)(cheng)座:先輕輕松動一下軸(zhou)(zhou)承(cheng)(cheng)座后用拆卸螺栓頂(ding)起軸(zhou)(zhou)承(cheng)(cheng)座,并(bing)(bing)且沿著(zhu)泵軸(zhou)(zhou)往(wang)上提而卸下,再用噴(pen)氣燃料清(qing)洗(xi)軸(zhou)(zhou)承(cheng)(cheng)及座,裝(zhuang)前晾(liang)干并(bing)(bing)涂抹少(shao)許20號機械油用來潤滑保(bao)護。
拆密(mi)封(feng)座:擰下密(mi)封(feng)座壓緊螺(luo)母(mu),輕輕卸下密(mi)封(feng)座并清洗。
河曲機械密封裝(zhuang)配:在動、靜環(huan)鏡面上(shang)(shang)涂一(yi)層潔凈的20號潤(run)滑油,導軸(zhou)承座(zuo)也抹上(shang)(shang)潤(run)滑油,先(xian)把(ba)(ba)靜環(huan)輕輕定位裝(zhuang)入導軸(zhou)承座(zuo),再在泵(beng)軸(zhou)上(shang)(shang)抹上(shang)(shang)潤(run)滑油,把(ba)(ba)動環(huan)部(bu)分輕輕裝(zhuang)入泵(beng)軸(zhou)上(shang)(shang),用手(shou)輕推密封(feng)環(huan)應能伸縮自如(ru),注意動、靜環(huan)部(bu)分的防(fang)轉(zhuan)部(bu)位需裝(zhuang)配到位。
裝(zhuang)(zhuang)(zhuang)聯(lian)(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)(qi):在電機(ji)軸(zhou)(zhou)(zhou)頭(tou)上(shang)(shang)裝(zhuang)(zhuang)(zhuang)上(shang)(shang)擋圈,裝(zhuang)(zhuang)(zhuang)上(shang)(shang)一(yi)半聯(lian)(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)(qi),再在泵軸(zhou)(zhou)(zhou)端和聯(lian)(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)(qi)槽內裝(zhuang)(zhuang)(zhuang)上(shang)(shang)擋塊并用梅花(hua)扳(ban)手(shou)擰緊螺栓;再裝(zhuang)(zhuang)(zhuang)上(shang)(shang)另一(yi)半聯(lian)(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)(qi)擰上(shang)(shang)內六角(jiao)螺釘。安裝(zhuang)(zhuang)(zhuang)聯(lian)(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)(qi)正確的(de)檢查要(yao)(yao)求:對(dui)分式聯(lian)(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)(qi)上(shang)(shang)下(xia)間(jian)隙需要(yao)(yao)均勻,用手(shou)盤動(dong)聯(lian)(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)(qi)幾圈檢查轉動(dong)的(de)靈活性。
裝(zhuang)密(mi)封座:先將(jiang)密(mi)封座裝(zhuang)入橡(xiang)膠油封,再把密(mi)封座裝(zhuang)入泵蓋(gai)并壓(ya)在軸承(cheng)座上(shang),擰緊(jin)螺(luo)母,確(que)保所有(you)安(an)裝(zhuang)螺(luo)釘(ding)緊(jin)固(gu)(gu)。當安(an)裝(zhuang)螺(luo)釘(ding)被用(yong)作密(mi)封與軸之(zhi)間的驅動時,軸應打埋(mai)頭孔來(lai)加固(gu)(gu)連接(jie),緊(jin)固(gu)(gu)壓(ya)蓋(gai)螺(luo)栓(shuan)時應該平穩緊(jin)固(gu)(gu),并且不要使壓(ya)蓋(gai)受彈力。在可(ke)能的地方使用(yong)4個以(yi)上(shang)螺(luo)釘(ding)的等(deng)間距壓(ya)蓋(gai),緊(jin)固(gu)(gu)壓(ya)蓋(gai)螺(luo)栓(shuan)時,用(yong)塞尺(chi)檢查軸與壓(ya)蓋(gai)之(zhi)間的間隙,這在密(mi)封腔對(dui)壓(ya)蓋(gai)不導向時,顯得特(te)別(bie)重要,因為(wei)壓(ya)蓋(gai)必須(xu)對(dui)中。
