M'mafakitale apadziko lonse lapansi a migodi, migodi, ndi kukonza zinthu zosiyanasiyana, ma crushers ndiye zida zofunika kwambiri pakupanga zinthu, ndipo zida zawo zosweka—kuphatikizapo mbale za jaw, ma cone liners, blow bars, ndi nsonga za hammer—ndizo zofunika kwambiri. Kwa ogwiritsa ntchito, kusintha pafupipafupi zida zosweka sikuti kumangowonjezera ndalama zogulira mwachindunji komanso kumayambitsa nthawi yosakonzekera, yomwe ingachepetse kugwira ntchito bwino kwa zinthu ndi 15-25% pachaka, malinga ndi ziwerengero za makampani. Ogwiritsa ntchito ambiri amangoyang'ana kwambiri pamtengo wogulira zida zosweka, koma amanyalanyaza zomwe zimayambitsa kulephera msanga, zomwe zimapangitsa kuti pakhale kusintha kobwerezabwereza komanso kukwera kwa ndalama. Nkhaniyi ikufotokoza zomwe zimayambitsa kulephera kwa zida zosweka, ndipo imagawana njira zovomerezeka ndi makampani kuti ziwonjezere nthawi yogwirira ntchito, kuthandiza ogwiritsa ntchito kukonza mtengo wonse wa umwini (TCO) ndikuwonjezera kupitiriza kwa ntchito.
Zifukwa Zazikulu Zolepheretsa Kuvala Ziwalo Mwamsanga
Kumvetsetsa njira zolephera ndi gawo loyamba pakuwonjezera nthawi yogwira ntchito ya zida zosweka. Deta ya makampani ikuwonetsa kuti kulephera kwa zida zosweka msanga kupitirira 90% kumachokera ku zifukwa zinayi zazikulu, zomwe zambiri mwa izo ndi zodziwikiratu komanso zopewera.
Chifukwa chachikulu, chomwe chimayambitsa kuwonongeka kwa magawo opitilira 80%, ndi kuwonongeka kwa mamba. Izi zimachitika pamene tinthu ta mchere tolimba, towawa mu chakudya timakanda, kudula, ndikuwononga pamwamba pa gawo losweka panthawi yophwanya. Kuopsa kwa kuwonongeka kwa mamba kumalumikizidwa mwachindunji ndi kuuma kwa chakudya: mwachitsanzo, miyala ya silika yayitali monga granite, basalt, ndi chitsulo imayambitsa kuwonongeka mwachangu kuposa zinthu zofewa monga miyala yamchere kapena malasha. Ngakhale pazinthu zomwe sizimawonongeka kwambiri, kusinthasintha kwa mamba a chakudya ndi tinthu tating'onoting'ono kwambiri kumatha kufulumizitsa kuwonongeka kwa mamba, chifukwa zinyalala zazing'ono zimagwira ntchito ngati sandpaper pakati pa zigawo zophwanya.
Njira yachiwiri yolephera kwambiri ndi kulephera kutopa chifukwa cha impact fatigue. Izi zimachitika makamaka mu nsagwada zophwanyika, impact crushers, ndi hammer crushers, komwe ziwalo zosweka zimakumana ndi mphamvu zambiri mobwerezabwereza kuchokera ku zinthu zodyetsera. Pakapita nthawi, katundu wozungulira wa impact umapanga ming'alu yaying'ono pamwamba pa gawolo; ming'aluyi imakula ndikugwiritsa ntchito nthawi zonse, zomwe zimapangitsa kuti chigambacho chisweke, chisweke, kapena kusweka kwathunthu kwa gawolo. Kulephera kulephera nthawi zambiri kumawonjezeka chifukwa cha zinthu zazikulu zodyetsera, zinthu zakunja zomwe sizingasweke (monga zidutswa zachitsulo kapena zobowola) mu chakudya, komanso kuchuluka kosasinthasintha kwa chakudya komwe kumayambitsa kuchuluka kwadzidzidzi kwa zinthu.
Chachitatu, kuwonongeka kwa zinthu zowononga ndi chinthu chomwe nthawi zambiri sichimaganiziridwa koma chimakhudza kwambiri ntchito za migodi. Pokonza miyala yokhala ndi sulfure yambiri, mchere wa asidi, kapena zinthu zonyowa, dzimbiri la mankhwala limafooketsa kapangidwe ka chitsulo cha gawo lowonongeka. Kudzimbiritsa kumapanga mabowo ndi malo obowoka pamwamba, zomwe sizimangochepetsa makulidwe ogwira ntchito a gawolo komanso zimakhala malo oyambira kuwonongeka kwa zinthu zowononga komanso kufalikira kwa ming'alu. M'malo onyowa, kuphatikiza kwa dzimbiri ndi kusweka kumatha kuchepetsa moyo wa gawo losweka ndi 40% poyerekeza ndi momwe ntchito youma imagwirira ntchito.
Pomaliza, kuyika kosayenera ndi ntchito yosakhazikika kumabweretsa kulephera kwakukulu msanga. Ngakhale zida zogwiritsidwa ntchito bwino kwambiri zimalephera msanga ngati zitayikidwa molakwika: mwachitsanzo, mipata yosayenera yolumikizira, kulimba kosakwanira kwa zomangira, kapena kusakhazikika bwino kwa zigawo kungayambitse kufalikira kosagwirizana kwa kupsinjika, kuwonongeka kwambiri m'malo osiyanasiyana, komanso kusweka mwadzidzidzi. Kuphatikiza apo, magawo olakwika ogwiritsira ntchito crusher—monga kukhazikika kwa mbali yotsekedwa kwambiri (CSS), liwiro losagwirizana la rotor, kapena kugwira ntchito mopitirira muyeso kwa nthawi yayitali—zidzathandizanso kusweka ndikufupikitsa moyo wautumiki.
Njira Zotsimikizika Zowonjezerera Moyo Wonse wa Utumiki wa Ziwalo Zovala
Kutalikitsa nthawi yogwira ntchito ya zida zophwanyira sikuti kungosankha zinthu zovuta kwambiri, komanso kuphatikiza kufananiza zinthu, kukonza bwino njira, ndi kukonza koyenera. Pansipa pali njira zomwe zingagwiritsidwe ntchito, zoyesedwa m'munda zomwe zimapereka zotsatira zoyezeka kwa ogwiritsa ntchito.
Choyamba, sankhani zipangizo zoyenera kugwiritsa ntchito. Cholakwika chachikulu chomwe ogwiritsa ntchito amachita ndi kusankha gawo lovala lofanana ndi la mtundu umodzi, m'malo mogwirizanitsa zinthuzo ndi ntchitoyo. Mwachitsanzo, chitsulo cha austenitic manganese (monga Mn13Cr2) ndi chabwino kwambiri pa zinthu zophwanyika kwambiri, chifukwa chimagwira ntchito molimbika pamene chagwedezeka kuti chipange malo osawonongeka pamene chikusunga kulimba kwa mkati. Pa zinthu zotsika mtengo komanso zosawonongeka kwambiri, chitsulo choyera cha chromium chokhala ndi chromium yambiri chimapereka kukana kwabwino kwa kuvulala. Pa zinthu zovuta zogwirira ntchito zomwe zimakhala ndi kuvulala kwakukulu komanso koopsa kwambiri, zinthu zopangidwa ndi bimetallic composite zimaphatikiza kulimba kwa chitsulo cha manganese ndi kukana kwa kuvulala kwa alloy ya chromium yambiri, zomwe zimapangitsa kuti ntchito ikhale yayitali ndi 30-50% kuposa zipangizo chimodzi. Kugwira ntchito ndi fakitale yaukadaulo yomwe ingathe kusintha kapangidwe ka zinthu kutengera zinthu zanu zodyera ndi momwe ntchito ikuyendera ndikofunikira kwambiri kuti pakhale moyo wautali wa gawo.
Chachiwiri, konzani bwino kayendetsedwe ka chakudya kuti muchepetse kusowa kosafunikira. Kuonetsetsa kuti kukula kwa chakudya kuli mkati mwa zomwe chida chophwanyira chimafuna kumachotsa kuchuluka kwa mphamvu zomwe zimapangitsa kuti ming'alu isagwire ntchito. Kuyika zida zowunikira zitsulo ndi zolekanitsa maginito mu mzere wa chakudya kumachotsa zinthu zakunja zomwe sizingaphwanyike, ndikuletsa kuwonongeka kwakukulu kwa ziwalo zosweka. Kuphatikiza apo, kusunga kuchuluka kwa chakudya kofanana komanso kofanana kumapewa kunyamula katundu kosagwirizana komanso kusowa kwa malo, pomwe kuyesa pasadakhale kuchotsa tinthu tating'onoting'ono tambiri kumachepetsa kusowa kwa mphamvu pakati pa zigawo zosweka.
Chachitatu, gwiritsani ntchito njira zokhazikika zokhazikitsira komanso zosamalira nthawi zonse. Kutsatira malangizo okhazikitsa a wopanga kumaonetsetsa kuti zikugwirizana bwino komanso kugawa mphamvu pa gawo lonse losweka. Pa mbale zophwanyira nsagwada, kuzungulira nthawi zonse mbale zokhazikika komanso zosunthika kungathandize kuti pakhale njira zosweka, chifukwa gawo la pansi la mbale zosweka nthawi zambiri limasweka mofulumira kuposa gawo lapamwamba. Kuyang'ana maso tsiku ndi tsiku komanso kuyang'ana nthawi zonse mphamvu ya zomangira kumatha kuwona zinthu zotayirira kapena zizindikiro zoyambirira za kuwonongeka zisanagwere kulephera kwakukulu, kuchepetsa nthawi yopuma yosakonzekera.
Pomaliza, gwiritsani ntchito ukadaulo wapamwamba wopangira zinthu ndi kutentha kuchokera kwa ogulitsa odalirika. Kugwira ntchito kwa ziwalo zosweka sikudalira kokha kapangidwe ka zinthu komanso njira yopangira. Njira zopangira zinthu molondola, monga kutayika kwa thovu, zimaonetsetsa kuti zinthuzo zikhale zofanana komanso kuti zinthuzo zikhale zopanda chilema, pomwe njira yabwino yopangira zinthuzo (monga kulimbitsa madzi achitsulo cha manganese ndi kuzima kwa chitsulo cha chromium) imakulitsa kuuma ndi kulimba kwa zinthuzo. Kampani yopangira zinthu zosweka yomwe ili ndi ukadaulo wowongolera bwino khalidwe imatha kupereka ziwalo zosweka ndi magwiridwe antchito okhazikika, kupewa kusintha kwa batch-to-batch komwe kumabweretsa moyo wosayembekezereka.
Mapeto
Moyo wa ntchito ya zida zophwanyira zinthu zophwanyira zinthu ndi zotsatira za kuphatikiza kusankha zinthu, momwe zimagwirira ntchito, ndi njira zosamalira. Pomvetsetsa zomwe zimayambitsa kulephera ndikugwiritsa ntchito njira zomwe zafotokozedwa pamwambapa, ogwiritsa ntchito amatha kukulitsa kwambiri moyo wa zida zophwanyira zinthu, kuchepetsa nthawi yogwira ntchito, komanso kuchepetsa ndalama zonse zopangira.
Monga fakitale yaukadaulo yodziwika bwino pakupanga zida zogwirira ntchito zopopera ndi zaka zambiri, tadzipereka kupereka njira zogwirira ntchito bwino komanso zopangidwira makasitomala athu zomwe zimagwirizana ndi momwe makasitomala athu amagwirira ntchito. Gulu lathu la akatswiri a zitsulo ndi ogwira ntchito zauinjiniya amagwira ntchito limodzi ndi makasitomala kuti akonze bwino kusankha zinthu ndi kapangidwe ka zigawo, kuthandiza ogwira ntchito zamigodi ndi miyala padziko lonse lapansi kuti apeze phindu lalikulu komanso magwiridwe antchito.
