安陸機械密封利用(yong)機械方式(shi)(shi)傳(chuan)(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)力(li)(li)和(he)(he)(he)(he)(he)運(yun)動(dong)(dong)(dong)的(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong),機械傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)在機械工程(cheng)中應(ying)用(yong)非常廣泛(fan),有多種形式(shi)(shi),主要包括(kuo)皮(pi)帶傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、齒(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、蝸(gua)桿(gan)蝸(gua)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、齒(chi)輪(lun)齒(chi)條(tiao)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)和(he)(he)(he)(he)(he)螺旋傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)等(deng)。齒(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)能夠(gou)用(yong)于大(da)功率的(de)場(chang)合,傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)比準確,但一般要求較高的(de)制造精(jing)度(du)(du)和(he)(he)(he)(he)(he)安裝(zhuang)精(jing)度(du)(du)。還(huan)有一類(lei)是靠機件間的(de)摩(mo)(mo)擦(ca)力(li)(li)傳(chuan)(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)力(li)(li)和(he)(he)(he)(he)(he)運(yun)動(dong)(dong)(dong)的(de)摩(mo)(mo)擦(ca)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong),包括(kuo)帶傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)和(he)(he)(he)(he)(he)摩(mo)(mo)擦(ca)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)等(deng)。摩(mo)(mo)擦(ca)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)容易實現無級變速,可以適(shi)應(ying)軸間距較大(da)的(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)場(chang)合,而過載打滑還(huan)能起到緩沖和(he)(he)(he)(he)(he)保護傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)裝(zhuang)置的(de)作用(yong),但這種傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)一般不(bu)能用(yong)于大(da)功率的(de)場(chang)合,也不(bu)能保證準確的(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)比。
傳動形式多,但是安陸機械密封的(de)更換工(gong)(gong)作(zuo)大同小異,首先(xian)拆(chai)(chai)前需確認電(dian)機(ji)處于檢修狀態,擰(ning)下加油螺塞,用(yong)吸管把密(mi)封座(zuo)腔(qiang)內的(de)潤滑油吸出。準(zhun)備好放(fang)(fang)置泵零件(jian)(jian)的(de)工(gong)(gong)作(zuo)臺(tai)及拆(chai)(chai)裝工(gong)(gong)具,切(qie)勿(wu)任意亂放(fang)(fang)亂用(yong),避免碰(peng)壞(huai)泵的(de)零部件(jian)(jian)。
拆(chai)對分式聯軸(zhou)器:先把聯軸(zhou)器的固(gu)定內六角螺釘擰下(xia)(xia)(xia)來,再輕輕把聯軸(zhou)器的一半(ban)(ban)從軸(zhou)上慢(man)慢(man)拉下(xia)(xia)(xia),注意不要掉了(le),再用梅花扳手擰下(xia)(xia)(xia)泵(beng)軸(zhou)吊(diao)緊(jin)螺栓和擋塊,讓葉輪慢(man)慢(man)下(xia)(xia)(xia)沉至泵(beng)體,然后拆(chai)下(xia)(xia)(xia)另外一半(ban)(ban)聯軸(zhou)器,拿下(xia)(xia)(xia)泵(beng)軸(zhou)擋圈。
拆卸安陸機械密封:抓住密(mi)封彈簧(huang)順著(zhu)泵軸往上提,就能拆下來了(le)。
拆卸(xie)并(bing)清洗軸(zhou)承(cheng)座(zuo)(zuo):先輕輕松動一下(xia)軸(zhou)承(cheng)座(zuo)(zuo)后用拆卸(xie)螺栓(shuan)頂起軸(zhou)承(cheng)座(zuo)(zuo),并(bing)且(qie)沿著泵軸(zhou)往上(shang)提(ti)而卸(xie)下(xia),再(zai)用噴氣燃(ran)料清洗軸(zhou)承(cheng)及座(zuo)(zuo),裝前晾干并(bing)涂抹少許20號機械油用來潤滑保護(hu)。
拆密(mi)(mi)封(feng)座(zuo):擰下(xia)密(mi)(mi)封(feng)座(zuo)壓緊(jin)螺母(mu),輕輕卸下(xia)密(mi)(mi)封(feng)座(zuo)并(bing)清洗。
安陸機械密封裝(zhuang)配(pei):在動、靜環(huan)(huan)鏡面上涂一層潔凈的20號(hao)潤(run)滑油,導(dao)軸(zhou)(zhou)承(cheng)(cheng)座(zuo)也(ye)抹(mo)上潤(run)滑油,先把靜環(huan)(huan)輕(qing)輕(qing)定位(wei)裝(zhuang)入(ru)導(dao)軸(zhou)(zhou)承(cheng)(cheng)座(zuo),再在泵軸(zhou)(zhou)上抹(mo)上潤(run)滑油,把動環(huan)(huan)部分(fen)輕(qing)輕(qing)裝(zhuang)入(ru)泵軸(zhou)(zhou)上,用手輕(qing)推密封環(huan)(huan)應(ying)能伸縮自如,注意動、靜環(huan)(huan)部分(fen)的防轉(zhuan)部位(wei)需(xu)裝(zhuang)配(pei)到(dao)位(wei)。
裝(zhuang)(zhuang)聯軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi):在(zai)電機(ji)軸(zhou)(zhou)(zhou)(zhou)頭上(shang)(shang)裝(zhuang)(zhuang)上(shang)(shang)擋圈(quan),裝(zhuang)(zhuang)上(shang)(shang)一半(ban)聯軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi),再在(zai)泵軸(zhou)(zhou)(zhou)(zhou)端和聯軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)槽內裝(zhuang)(zhuang)上(shang)(shang)擋塊并用梅花扳手擰緊螺栓(shuan);再裝(zhuang)(zhuang)上(shang)(shang)另一半(ban)聯軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)擰上(shang)(shang)內六角(jiao)螺釘。安裝(zhuang)(zhuang)聯軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)正確的檢查要求(qiu):對分式聯軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)上(shang)(shang)下間隙需要均勻(yun),用手盤動(dong)聯軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)幾圈(quan)檢查轉動(dong)的靈活(huo)性。
裝(zhuang)密(mi)封座:先將(jiang)密(mi)封座裝(zhuang)入橡膠油封,再把密(mi)封座裝(zhuang)入泵蓋并壓在軸(zhou)承座上,擰緊(jin)(jin)螺(luo)母(mu),確保(bao)所有安(an)裝(zhuang)螺(luo)釘緊(jin)(jin)固(gu)(gu)(gu)。當安(an)裝(zhuang)螺(luo)釘被用(yong)作密(mi)封與軸(zhou)之(zhi)間(jian)的(de)驅(qu)動時(shi)(shi),軸(zhou)應打埋頭孔來(lai)加固(gu)(gu)(gu)連接,緊(jin)(jin)固(gu)(gu)(gu)壓蓋螺(luo)栓(shuan)時(shi)(shi)應該平穩緊(jin)(jin)固(gu)(gu)(gu),并且不(bu)要使壓蓋受彈力(li)。在可能的(de)地方(fang)使用(yong)4個以(yi)上螺(luo)釘的(de)等間(jian)距壓蓋,緊(jin)(jin)固(gu)(gu)(gu)壓蓋螺(luo)栓(shuan)時(shi)(shi),用(yong)塞尺檢(jian)查(cha)軸(zhou)與壓蓋之(zhi)間(jian)的(de)間(jian)隙,這在密(mi)封腔(qiang)對壓蓋不(bu)導向時(shi)(shi),顯得特別重(zhong)要,因為壓蓋必(bi)須(xu)對中。
