發布(bu)時間:2021-06-01 15:17:49 人(ren)氣:172606 來(lai)源:川工密封

  隨州機械密封利用機(ji)械(xie)方式傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)力(li)和(he)運(yun)動(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong),機(ji)械(xie)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)在機(ji)械(xie)工程中應(ying)用非常廣泛,有多種形式,主要(yao)包括(kuo)皮(pi)帶(dai)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、蝸桿蝸輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)(chi)輪(lun)齒(chi)(chi)條(tiao)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)螺旋傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等。齒(chi)(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)能(neng)夠用于大功率的(de)(de)(de)場合,傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比(bi)準確,但(dan)一般(ban)要(yao)求較高的(de)(de)(de)制(zhi)造精度(du)和(he)安裝(zhuang)精度(du)。還有一類是靠機(ji)件間的(de)(de)(de)摩(mo)擦力(li)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)力(li)和(he)運(yun)動(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)摩(mo)擦傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong),包括(kuo)帶(dai)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)摩(mo)擦輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等。摩(mo)擦傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)容易(yi)實現(xian)無級變(bian)速,可以適應(ying)軸(zhou)間距較大的(de)(de)(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)場合,而過載(zai)打(da)滑還能(neng)起(qi)到(dao)緩沖和(he)保護傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)裝(zhuang)置的(de)(de)(de)作用,但(dan)這種傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)一般(ban)不(bu)能(neng)用于大功率的(de)(de)(de)場合,也不(bu)能(neng)保證(zheng)準確的(de)(de)(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比(bi)。

  傳動形式多,但是隨州機械密封的(de)(de)更換工(gong)作(zuo)大同小異,首先拆前需確認電機處于(yu)檢(jian)修狀態,擰下加油螺塞(sai),用吸管把密封座腔(qiang)內(nei)的(de)(de)潤滑油吸出。準(zhun)備好(hao)放(fang)置泵零(ling)件的(de)(de)工(gong)作(zuo)臺及(ji)拆裝工(gong)具(ju),切(qie)勿任意亂放(fang)亂用,避免碰壞泵的(de)(de)零(ling)部件。

  拆對分式聯軸(zhou)器(qi):先把聯軸(zhou)器(qi)的固(gu)定內六角螺釘擰下(xia)(xia)來,再輕(qing)輕(qing)把聯軸(zhou)器(qi)的一半從軸(zhou)上慢慢拉下(xia)(xia),注意不(bu)要(yao)掉了,再用梅花扳手擰下(xia)(xia)泵(beng)軸(zhou)吊緊螺栓和擋塊,讓葉(xie)輪慢慢下(xia)(xia)沉至(zhi)泵(beng)體(ti),然后拆下(xia)(xia)另外一半聯軸(zhou)器(qi),拿下(xia)(xia)泵(beng)軸(zhou)擋圈。

  拆卸隨州機械密封:抓(zhua)住密(mi)封(feng)彈簧順著泵(beng)軸往上提(ti),就(jiu)能拆下來了。

  拆(chai)卸并清(qing)洗軸承座:先輕輕松動一下軸承座后用(yong)拆(chai)卸螺栓(shuan)頂起軸承座,并且沿(yan)著泵軸往上提而卸下,再用(yong)噴氣(qi)燃(ran)料清(qing)洗軸承及(ji)座,裝前晾干并涂(tu)抹少(shao)許20號機械(xie)油用(yong)來潤滑保護。

  拆(chai)密(mi)(mi)封(feng)座(zuo):擰下(xia)密(mi)(mi)封(feng)座(zuo)壓緊螺母,輕輕卸下(xia)密(mi)(mi)封(feng)座(zuo)并清(qing)洗(xi)。

  隨州機械密封裝(zhuang)(zhuang)配:在(zai)動(dong)、靜(jing)(jing)環鏡面上(shang)(shang)涂一層潔凈(jing)的20號潤(run)(run)滑油,導(dao)軸(zhou)(zhou)承座(zuo)也抹上(shang)(shang)潤(run)(run)滑油,先(xian)把(ba)靜(jing)(jing)環輕輕定位裝(zhuang)(zhuang)入導(dao)軸(zhou)(zhou)承座(zuo),再在(zai)泵(beng)軸(zhou)(zhou)上(shang)(shang)抹上(shang)(shang)潤(run)(run)滑油,把(ba)動(dong)環部分輕輕裝(zhuang)(zhuang)入泵(beng)軸(zhou)(zhou)上(shang)(shang),用手輕推密(mi)封環應能(neng)伸縮自如(ru),注意動(dong)、靜(jing)(jing)環部分的防(fang)轉部位需裝(zhuang)(zhuang)配到位。

  裝聯(lian)(lian)(lian)軸(zhou)器(qi)(qi)(qi):在(zai)電機軸(zhou)頭上(shang)(shang)裝上(shang)(shang)擋圈,裝上(shang)(shang)一半聯(lian)(lian)(lian)軸(zhou)器(qi)(qi)(qi),再在(zai)泵軸(zhou)端和聯(lian)(lian)(lian)軸(zhou)器(qi)(qi)(qi)槽內(nei)裝上(shang)(shang)擋塊(kuai)并用梅花扳手擰緊螺栓;再裝上(shang)(shang)另一半聯(lian)(lian)(lian)軸(zhou)器(qi)(qi)(qi)擰上(shang)(shang)內(nei)六角螺釘。安裝聯(lian)(lian)(lian)軸(zhou)器(qi)(qi)(qi)正(zheng)確的檢查要求:對分式聯(lian)(lian)(lian)軸(zhou)器(qi)(qi)(qi)上(shang)(shang)下間隙需要均勻(yun),用手盤動(dong)聯(lian)(lian)(lian)軸(zhou)器(qi)(qi)(qi)幾(ji)圈檢查轉動(dong)的靈(ling)活性。

  裝密(mi)(mi)封座:先將密(mi)(mi)封座裝入橡(xiang)膠(jiao)油封,再把密(mi)(mi)封座裝入泵蓋(gai)(gai)并壓(ya)(ya)(ya)在軸承座上,擰緊螺(luo)母,確保(bao)所(suo)有安(an)裝螺(luo)釘緊固(gu)。當(dang)安(an)裝螺(luo)釘被用作密(mi)(mi)封與軸之間的(de)驅動時(shi),軸應(ying)打埋頭孔來加固(gu)連接(jie),緊固(gu)壓(ya)(ya)(ya)蓋(gai)(gai)螺(luo)栓(shuan)時(shi)應(ying)該平(ping)穩(wen)緊固(gu),并且不要(yao)(yao)使壓(ya)(ya)(ya)蓋(gai)(gai)受彈力。在可能的(de)地方使用4個以上螺(luo)釘的(de)等(deng)間距壓(ya)(ya)(ya)蓋(gai)(gai),緊固(gu)壓(ya)(ya)(ya)蓋(gai)(gai)螺(luo)栓(shuan)時(shi),用塞尺檢查(cha)軸與壓(ya)(ya)(ya)蓋(gai)(gai)之間的(de)間隙(xi),這在密(mi)(mi)封腔(qiang)對(dui)壓(ya)(ya)(ya)蓋(gai)(gai)不導(dao)向(xiang)時(shi),顯得特別重要(yao)(yao),因為壓(ya)(ya)(ya)蓋(gai)(gai)必須對(dui)中(zhong)。
