Makina Ophikira Ufa Wothira: "Woteteza Wosaoneka" Wolimbana ndi Dzimbiri la Chidebe
Makina ophikira ufa a CTPC mndandanda wa weld ndi zida zophikira zamagetsi zomwe zayambitsidwa ndi Chengdu Changtai Intelligent Equipment Co., Ltd., zoyenera mafakitale opanga chakudya cham'zitini ndi zitini zamafakitale. Pogwiritsa ntchito ukadaulo wamagetsi wothira madzi amagetsi amphamvu kwambiri, ali ndi zabwino monga kupaka utoto wofanana, kugwiritsa ntchito mosavuta, komanso kubwezeretsanso ufa wokha. Kudzera mu kuyika bwino magawo, kukhazikitsa ndi kugwiritsa ntchito kokhazikika, kukonza tsiku ndi tsiku, komanso kuthetsa mavuto, amatha kuteteza dzimbiri ndi dzimbiri mkati mwa zitini.
I. Malo Oyika Zipangizo ndi Ubwino Waukulu
Makina ophikira ufa wa CTPC mndandanda wa weld ndi chinthu chachikulu cha Chengdu Changtai Intelligent Equipment Co., Ltd. Opangidwira makamaka mafakitale opanga chakudya cham'zitini ndi mafakitale, amayang'ana kwambiri kupewa dzimbiri ndi kuteteza dzimbiri ku zomwe zili mkati mwa mipata yophikira ya matupi a zitini, kusinthana ndi chitetezo chamkati cha matupi a zitini ophimbidwa ndi mitundu yosiyanasiyana ya makina ophikira kumbuyo. Poyerekeza ndi njira yachikhalidwe yogwiritsira ntchito guluu, makinawa amagwiritsa ntchito ukadaulo wamagetsi amphamvu kwambiri, wokhala ndi zabwino monga kupaka yunifolomu popanda ma pores abwino, malo ogwirira ntchito opanda fungo, komanso kugwiritsa ntchito mosavuta. Kuphatikiza apo, ufawo ukhoza kubwezeretsedwanso zokha—kuti ufa wamtundu womwewo ukhale wofanana, palibe chifukwa chothira ufa wotsalawo mu chidebe ngati ugwiritsidwanso ntchito mkati mwa masiku asanu ndi awiri, zomwe zimachepetsa kwambiri zinyalala ndi kuipitsa.
II. Mfundo Yogwirira Ntchito, Kapangidwe ka Pakati ndi Njira Yokwanira
(I) Mfundo Yogwirira Ntchito
Ufa wa resin womwe umapopedwa ndi ejector umayikidwa mphamvu pambuyo podutsa mu electrostatic field yamagetsi amphamvu yopangidwa ndi singano yotulutsa mphamvu zamagetsi zambiri. Umalowetsedwa mkati mwa weld ya thupi la chitini motsatira njira ya mpweya, kotero kuti ufawo umamatira mwamphamvu ku thupi la chitini. Kenako, kudzera mu kutentha ndi chowumitsira chothandizira, ufawo umasungunuka ndikukhala pulasitiki, pamapeto pake kupanga filimu yoteteza pa weld.
(II) Kapangidwe ka Pakati
Zipangizozi zimapangidwa ndi zinthu zofunika kwambiri monga cholekanitsa ufa chotchinga ndi kugwedezeka, chidebe chosungiramo ufa, chidebe choperekera ufa, fyuluta yobwezeretsa, ejector, mkono wa ufa, ndi chivundikiro chobwezeretsa. Dzanja la ufa limatha kusintha malo ake opingasa komanso oyima kuti litsimikizire kupopera ufa molondola; chivundikiro chobwezeretsa chimagawidwa m'mitundu yayikulu ndi yaying'ono—chivundikiro chachikulu chili pamtunda wa 10-15mm kuchokera ku chidebe, ndipo chivundikiro chaching'ono chili ndi burashi yobwezeretsa ufa wochulukirapo; bokosi lobwezeretsa ndi kuchotsa chitsulo lili ndi maginito olimba omangidwa mkati, omwe amatha kuyamwa zonyansa zachitsulo mu ufa kuti atsimikizire kuyera kwa chophimba.
(III) Njira Yogwirira Ntchito
- 1. Gawo Lopereka Ufa: Ufa watsopano umalowa mu sikirini yogwedezeka kudzera mu choyatsira ufa ndi valavu yolumikizira chitoliro, kusefa zinyalala, kenako nkugwera mu chidebe chosungiramo ufa. Mpweya wotentha wopangidwa ndi fan yothira madzi umathira ufawo, womwe umalowa mu chidebe choperekera ufa kudzera mu kayendedwe ka mpweya.
- 2. Gawo Lopopera Ufa: Ejector imapanga vacuum kuti ichotse ufa womwe uli mu chidebe choperekera ufa, ndikusakaniza ndi mpweya wopanikizika kuti apange chisakanizo cha ufa ndi mpweya, ndikuupereka ku mlatho wopopera ufa kudzera m'dzanja la ufa. Nthawi yomweyo, jenereta yamagetsi yamphamvu imachaja ufawo.
- 3. Gawo Lomwe Limamatirira: Ufa wodzazidwa umamatirira bwino mkati mwa chidebe cha thupi pogwiritsa ntchito mphamvu yamagetsi yosasunthika, ndipo zitseko zazikulu ndi zazing'ono zobwezeretsa zimatengera ufa wochuluka womwe wafalikira.
- 4. Gawo Lobwezeretsa ndi Kuyenda kwa Madzi: Ufa wobwezeretsedwayo umachotsa zinyalala zachitsulo kudzera m'bokosi lochotsera chitsulo kenako nkulowanso mu chidebe chosungiramo ufa kuti ubwezeretsedwenso.
- 5. Gawo Lophikira: Thupi la chitini chopopera limalowa mu choumitsira, ndipo ufawo umasungunuka ndi kupangidwa pulasitiki kudzera mu kutentha kuti upange chophimba choteteza.
III. Magawo Ofunika ndi Zofunikira Zokhazikitsa
Magawo a magwiridwe antchito a zida ayenera kufananizidwa bwino: mphamvu yamagetsi ndi 380V ya magawo atatu a waya anayi, yokhala ndi zingwe zamagetsi za 4mm²; kuthamanga kwa mpweya wopanikizika kuyenera kufika pa 0.6MPa, ndikugwiritsa ntchito 100-200L/min, ndipo gwero la mpweya liyenera kuziziritsidwa ndi chowumitsira chapadera chozizira musanalowe mu makina. Poyika, tsindikani kwambiri pa nthaka: tengani ndodo zitatu zofiira zamkuwa zokhala ndi mainchesi a 15-20mm ndi kutalika kwa 180cm, sungunulani nati kapena pangani ndodo ya M12 kumapeto kwina, ndikunola kumapeto kwina. Ziyendetseni molunjika mu dothi lonyowa patali ndi 200cm, kenako lumikizani ndikumanga ndodo zitatu zamkuwa ndi zingwe zamkuwa za 60mm², kenako zilumikizeni ku makina ndi zingwe zamkuwa za 10mm². Pa kulumikizana ndi payipi, tikukulimbikitsani kugwiritsa ntchito chitoliro cha PVC cha mainchesi a 100mm kuti musunge kuti muwonetsetse kuti mzere wopangira ndi wabwino.
IV. Mitundu Yogwirira Ntchito ndi Zokonzera Ma Parameter
Ntchitoyi imagawidwa m'njira zodziyimira payokha komanso zamanja, zomwe zimatha kulamulidwa mosavuta kudzera pazenera logwira. Munjira yodziyimira payokha, nthawi yochedwetsa kutsogolo ndi kumbuyo yopopera ufa (kutsogolo 0.1-3s, kumbuyo 3-30s) ndi mphamvu yamagetsi yapamwamba (38-65KV, imakhala ndi phindu lalikulu pamene ufa uli wonyowa) zitha kukhazikitsidwa; munjira yodziyimira payokha, fan yobwezeretsa iyenera kuyatsidwa kaye musanachite ntchito monga kupopera ufa ndi kuyeretsa. Kuthamanga kwa mpweya ndi kayendedwe kake ziyenera kutsatira miyezo: kuthamanga kwa kupopera ufa 0.18-0.2MPa, kuthamanga kwa atomization 0.16-0.18MPa, kuthamanga kwa kuchira 0.3-0.4MPa, ndipo kuyenda konse kwa kupopera ufa + atomization + kukana kwakunja kwa kayendedwe kake kuyenera kukhala kochepera 18L/min.
V. Kuthetsa Mavuto ndi Kuwunika Ubwino
Zolakwika zofala zimatha kuthetsedwa molunjika: makulidwe osafanana a ufa akhoza kusinthidwa mwa kusintha kutalika kwa chivundikiro chachikulu chobwezeretsa kapena valavu yolumikizira ya chidebe choperekera ufa; kugwa kwa ufa kungakhale chifukwa cha mphamvu yokwanira yamagetsi kapena ufa wonyowa, kotero ndikofunikira kuwonjezera mphamvu yamagetsi kapena kuumitsa ufa; kukana bwino kwa utoto kumafuna kuyang'ana kutentha kouma.
Kuyang'anira ubwino kumagawidwa m'magawo awiri: musanaphike, ufa womwe umapopedwa pa chidebecho uyenera kuyang'aniridwa ndi maso mutachichotsa, ndipo uyenera kukhala wofanana makulidwe, kutsogolo ndi kumbuyo, kumanzere ndi kumanja, ndipo usagwe ukagwedezeka pang'onopang'ono ndi dzanja; mutatha kuphika ndi kuziziritsa, dulani mawonekedwe a X pa madigiri 90 m'magawo (kutsogolo, pakati, kumbuyo) kwa chidebecho ndi tsamba, tengani ngodya yakuthwa, ndipo kung'ambikako sikuyenera kupitirira 10mm kuti kusweke—kupitirira 12mm ndi chinthu cholakwika. Kuphatikiza apo, dulani mzere wa chidebecho ndi zokutira pamodzi ndi weld, kenako dulani mopingasa mpaka chitsulo chisweke, chophimbacho chisasweke, ndikukoka chophimba chonsecho pang'onopang'ono pa madigiri 60—kusweka mkati mwa 12mm ndikwabwino, ndipo choipa kwambiri sichiyenera kupitirira 20mm.
VI. Zofunikira pa Kusamalira ndi Kugwiritsa Ntchito Tsiku ndi Tsiku
Kukonza tsiku ndi tsiku kuyenera kuchitika nthawi zonse: kutsuka chinthu choyeretsera ufa ndi mpweya, chinthu choyeretsera fani, mbale yopumira mpweya, ndi bokosi lobwezeretsa ndi kuchotsa chitsulo sabata iliyonse; onani kudalirika kwa waya wothira pansi mwezi uliwonse. Mukagwiritsa ntchito, dziwani kuti chopopera ufa chimapangidwa ndi zinthu zopanda chitsulo, ndipo zomangira ziyenera kumangidwa mosamala kuti zisawonongeke; kuyeretsa ufa wotsala mu chidebe musanasinthe ufa kapena kuzimitsa kwa nthawi yayitali, ndikutseka chitseko chotseka mukatseka kuti ufa usatuluke, kuonetsetsa kuti zida zikugwira ntchito bwino kwa nthawi yayitali ndikumanga mzere wolimba woteteza kuti chakudya chikhale chotetezeka.
