頭屯河機械密封利用(yong)機(ji)械方式傳(chuan)遞動(dong)(dong)(dong)力(li)和(he)運(yun)動(dong)(dong)(dong)的(de)傳(chuan)動(dong)(dong)(dong),機(ji)械傳(chuan)動(dong)(dong)(dong)在機(ji)械工程中應用(yong)非常廣(guang)泛,有多種形式,主(zhu)要(yao)(yao)包括(kuo)皮(pi)帶傳(chuan)動(dong)(dong)(dong)、齒輪傳(chuan)動(dong)(dong)(dong)、鏈傳(chuan)動(dong)(dong)(dong)、蝸桿蝸輪傳(chuan)動(dong)(dong)(dong)、齒輪齒條傳(chuan)動(dong)(dong)(dong)和(he)螺旋傳(chuan)動(dong)(dong)(dong)等(deng)(deng)。齒輪傳(chuan)動(dong)(dong)(dong)能(neng)夠用(yong)于大(da)(da)功率的(de)場(chang)合,傳(chuan)動(dong)(dong)(dong)比準確,但(dan)一般要(yao)(yao)求較高的(de)制(zhi)造精度和(he)安裝精度。還(huan)有一類是靠(kao)機(ji)件間的(de)摩(mo)擦(ca)力(li)傳(chuan)遞動(dong)(dong)(dong)力(li)和(he)運(yun)動(dong)(dong)(dong)的(de)摩(mo)擦(ca)傳(chuan)動(dong)(dong)(dong),包括(kuo)帶傳(chuan)動(dong)(dong)(dong)、繩傳(chuan)動(dong)(dong)(dong)和(he)摩(mo)擦(ca)輪傳(chuan)動(dong)(dong)(dong)等(deng)(deng)。摩(mo)擦(ca)傳(chuan)動(dong)(dong)(dong)容易(yi)實(shi)現(xian)無(wu)級變速,可以適應軸間距較大(da)(da)的(de)傳(chuan)動(dong)(dong)(dong)場(chang)合,而過載打滑還(huan)能(neng)起到(dao)緩沖和(he)保護傳(chuan)動(dong)(dong)(dong)裝置(zhi)的(de)作(zuo)用(yong),但(dan)這種傳(chuan)動(dong)(dong)(dong)一般不能(neng)用(yong)于大(da)(da)功率的(de)場(chang)合,也不能(neng)保證準確的(de)傳(chuan)動(dong)(dong)(dong)比。
傳動形式多,但是頭屯河機械密封的更換工(gong)作(zuo)大同小異,首先拆(chai)(chai)前需確認(ren)電機處于檢修狀(zhuang)態,擰下加油(you)螺塞,用吸管把密(mi)封座腔內的潤滑油(you)吸出。準備好放(fang)置泵(beng)(beng)零(ling)件(jian)的工(gong)作(zuo)臺及(ji)拆(chai)(chai)裝工(gong)具,切勿(wu)任意(yi)亂放(fang)亂用,避免碰(peng)壞泵(beng)(beng)的零(ling)部件(jian)。
拆對分式聯(lian)軸(zhou)(zhou)(zhou)(zhou)器:先把聯(lian)軸(zhou)(zhou)(zhou)(zhou)器的固定內六角螺釘擰下(xia)(xia)來,再輕(qing)(qing)輕(qing)(qing)把聯(lian)軸(zhou)(zhou)(zhou)(zhou)器的一半從軸(zhou)(zhou)(zhou)(zhou)上慢(man)慢(man)拉(la)下(xia)(xia),注意不要(yao)掉了,再用梅(mei)花(hua)扳(ban)手擰下(xia)(xia)泵(beng)(beng)軸(zhou)(zhou)(zhou)(zhou)吊緊螺栓和擋塊,讓葉(xie)輪慢(man)慢(man)下(xia)(xia)沉至泵(beng)(beng)體,然后拆下(xia)(xia)另外一半聯(lian)軸(zhou)(zhou)(zhou)(zhou)器,拿下(xia)(xia)泵(beng)(beng)軸(zhou)(zhou)(zhou)(zhou)擋圈。
拆卸頭屯河機械密封:抓住密封彈簧順著泵軸往上提,就能拆下來了(le)。
拆卸(xie)并(bing)清洗軸(zhou)(zhou)承座:先輕輕松動一下軸(zhou)(zhou)承座后(hou)用(yong)拆卸(xie)螺(luo)栓頂起軸(zhou)(zhou)承座,并(bing)且(qie)沿著(zhu)泵軸(zhou)(zhou)往上提(ti)而卸(xie)下,再用(yong)噴氣燃(ran)料清洗軸(zhou)(zhou)承及(ji)座,裝(zhuang)前(qian)晾(liang)干并(bing)涂抹少(shao)許20號(hao)機械油用(yong)來(lai)潤(run)滑(hua)保(bao)護。
拆(chai)密(mi)封座(zuo):擰(ning)下(xia)(xia)密(mi)封座(zuo)壓緊螺母,輕輕卸下(xia)(xia)密(mi)封座(zuo)并(bing)清洗。
頭屯河機械密封裝(zhuang)(zhuang)配:在(zai)動(dong)(dong)、靜(jing)環鏡面上涂一層潔凈的(de)20號潤滑(hua)(hua)油(you)(you),導(dao)軸(zhou)(zhou)承(cheng)(cheng)座(zuo)也抹(mo)上潤滑(hua)(hua)油(you)(you),先(xian)把靜(jing)環輕(qing)輕(qing)定(ding)位裝(zhuang)(zhuang)入導(dao)軸(zhou)(zhou)承(cheng)(cheng)座(zuo),再在(zai)泵(beng)軸(zhou)(zhou)上抹(mo)上潤滑(hua)(hua)油(you)(you),把動(dong)(dong)環部(bu)分輕(qing)輕(qing)裝(zhuang)(zhuang)入泵(beng)軸(zhou)(zhou)上,用手輕(qing)推密封環應能伸(shen)縮自如,注意動(dong)(dong)、靜(jing)環部(bu)分的(de)防轉(zhuan)部(bu)位需裝(zhuang)(zhuang)配到位。
裝聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)(qi):在電機軸(zhou)(zhou)(zhou)(zhou)頭上(shang)(shang)裝上(shang)(shang)擋圈,裝上(shang)(shang)一半聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)(qi),再(zai)在泵軸(zhou)(zhou)(zhou)(zhou)端和聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)(qi)槽內裝上(shang)(shang)擋塊并(bing)用梅花扳手(shou)擰(ning)緊螺栓;再(zai)裝上(shang)(shang)另一半聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)(qi)擰(ning)上(shang)(shang)內六角(jiao)螺釘。安(an)裝聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)(qi)正確(que)的檢(jian)查要求:對分式聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)(qi)上(shang)(shang)下間(jian)隙(xi)需要均勻(yun),用手(shou)盤動聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)(qi)幾(ji)圈檢(jian)查轉(zhuan)動的靈活性。
裝(zhuang)(zhuang)密(mi)(mi)(mi)封(feng)(feng)座(zuo):先將密(mi)(mi)(mi)封(feng)(feng)座(zuo)裝(zhuang)(zhuang)入橡(xiang)膠油封(feng)(feng),再把密(mi)(mi)(mi)封(feng)(feng)座(zuo)裝(zhuang)(zhuang)入泵蓋并壓(ya)在(zai)軸(zhou)(zhou)承座(zuo)上(shang)(shang),擰緊螺(luo)(luo)母,確(que)保所有(you)安裝(zhuang)(zhuang)螺(luo)(luo)釘緊固(gu)。當(dang)安裝(zhuang)(zhuang)螺(luo)(luo)釘被用(yong)作密(mi)(mi)(mi)封(feng)(feng)與軸(zhou)(zhou)之間(jian)的(de)驅動時,軸(zhou)(zhou)應(ying)打埋頭孔來加固(gu)連接,緊固(gu)壓(ya)蓋螺(luo)(luo)栓時應(ying)該平穩緊固(gu),并且不(bu)要(yao)使(shi)壓(ya)蓋受彈力。在(zai)可(ke)能的(de)地方使(shi)用(yong)4個以(yi)上(shang)(shang)螺(luo)(luo)釘的(de)等間(jian)距壓(ya)蓋,緊固(gu)壓(ya)蓋螺(luo)(luo)栓時,用(yong)塞(sai)尺檢(jian)查軸(zhou)(zhou)與壓(ya)蓋之間(jian)的(de)間(jian)隙,這在(zai)密(mi)(mi)(mi)封(feng)(feng)腔對壓(ya)蓋不(bu)導向時,顯得特(te)別重(zhong)要(yao),因(yin)為(wei)壓(ya)蓋必須對中。
