Kobelco mini excavator eco-zatsopano? 

Kobelco Mini Excavator Eco-Innovations: A Ground-Level View

Mukamva zatsopano za eco zikugundidwa pa pepala la mini excavator, zimakhala zosavuta kukayikira. Kodi ndi bokosi lina lazamalonda, kapena pali china chake chomwe chikusintha pansi pa hood? Nditakhala zaka zambiri pamasamba omwe makinawa ndi ogwirira ntchito, ndawonapo kusintha kuchokera kumagetsi amphamvu kupita kukusakanizikirako kwamphamvu komanso udindo. Mayendedwe a Kobelco pano ndi ochepa pamutu wonyezimira komanso zambiri zamitundu ingapo yadala, nthawi zina zobisika, zosankha zaukadaulo zomwe zimawonjezera. Sikuti kukhala wobiriwira kwambiri chifukwa cha izo; ndi za kuthetsa mavuto enieni a malo - mtengo wamafuta, zoletsa phokoso, mutu wokonza - ndi zothetsera zomwe zimakhala zopepuka. Ndiko kusiyanitsa komwe kuli kofunikira kwenikweni.

Kusindikiza Eco mu Powerplant

Mtima wa zokambirana nthawi zonse ndi injini. Kobelco sanangogwera mu injini yogwirizana ndi Tier 4 Final ndikuyitcha tsiku. Zatsopano zenizeni, mu zitsanzo monga 17SR kapena 35SR, zili mu kuphatikiza. Ndilo ukwati wa dizilo yoyaka bwino yokhala ndi makina a hydraulic omwe salimbana nawo. Ndimakumbukira kuyendetsa makina akale komwe mumatha kumva kuti ma hydraulic akumeza mafuta. Makina atsopano amagwiritsa ntchito zomwe amakonda kuzitcha kukhathamiritsa kwa hydraulic. Pochita, izi zikutanthauza kuti mpope sikungotaya madzi ochulukirapo pa valve yothandizira; imagwirizana ndi zomwe mukufuna pa joystick. Simukuwotcha dizilo kuti mutenthe mafuta a hydraulic mosafunikira.

Pali zotsatirapo zothandiza pano zomwe sizipeza nthawi yokwanira yopuma: kuyendetsa kutentha. Dongosolo logwira ntchito bwino limatulutsa kutentha kocheperako. Pamalo ocheperako akutawuni kapena mkati mwa nyumba, ndicho chinthu chachikulu. Phukusi lozizira likhoza kukhala laling'ono, makinawo amatha kuzizira, ndipo mumapeza kupanikizika kochepa pazigawo. Ndawonapo ma hoses ndi zosindikizira zimatenga nthawi yayitali pamakina pomwe ma hydraulics samakhala ndi mantha nthawi zonse. Ndilo luso lachilengedwe lomwe limafika pachimake mwachindunji-nthawi yocheperako, magawo ochepa.

Koma si zonse zangwiro. Kusintha kwa injini zapamwambazi kunabweretsa mavuto odziwika bwino a mano. Poyambirira, makontrakitala ena omwe ndimawadziwa anali osamala ndi machitidwe ovuta pambuyo pa chithandizo. Mantha a DPF yotsekeka Lolemba m'mawa ndi enieni. Yankho la Kobelco, lomwe likuwoneka kuti likugwira ntchito, linali kupanga ma mayendedwe osinthika omwe amakhala osasunthika komanso amaphatikiza deta yamakina kuti athandizire ogwira ntchito mwachangu. Sizopusa, koma zikuwonetsa kuti amaganizira za munthu yemwe ali m'galimotoyo, osati kungoyesa kuyesa kwa mpweya.

Idle Logic ndi Nthano ya Nthawi Zonse

Izi zitha kuwoneka zazing'ono, koma kuyimitsidwa kwa injini ndi chimodzi mwazinthu zomwe zimawulula yemwe adakhalapo patsamba. Kusintha kosasinthika pamakina ambiri kumakhala kowopsa kwambiri - kumatseka pakatha mphindi zisanu osagwira ntchito. Patsamba lotanganidwa, iyi ndi njira yabwino kwambiri yokwiyitsira opareshoni yanu ndikuwononga choyambira chanu. Machitidwe a Kobelco amakhala osinthika kwambiri kapena, nthawi zina, anzeru. Amatha kutengera kutentha kwamafuta a hydraulic kapena voltage ya batri. Cholinga sikutseka chifukwa cha izo; ndiko kudula zinyalala zamafuta panthaŵi yopuma kwenikweni, monga panthaŵi yopuma yachakudya chamasana kapena kudikirira kuti galimoto ikwezedwe.

Chiyeso chenicheni chinali mu ntchito zothandizira. Tinali ndi 25SR-2 pa ntchito yoyika mapaipi pomwe makinawo amakhala osasunthika koma akugwiritsa ntchito nyundo pafupipafupi. Malingaliro akale mwina adatseka injini pakati pa kuphulika. Dongosolo la Kobelco likuwoneka kuti likuzindikira kuti dera lothandizira linali ndi zida ndikuimitsidwa. Ndilo mainjiniya oganiza. Imapulumutsa mwina lita imodzi yamafuta patsiku, koma kudutsa zombo zonse, ndizothandiza. Chofunika kwambiri, sichimasokoneza mayendedwe a ntchito.

Kumene opanga ena amangowonjezera batani la eco-mode, Kobelco nthawi zambiri amawotcha muzowongolera. Sikuti nthawi zonse mumasankha kukhala osachita bwino. Dongosolo la ma hydraulic limasinthasintha kuti likhale lotsika komanso kuthamanga kwambiri ngati kuli kotheka, zomwe nthawi zambiri zimakhala zomwe mukufuna kukumba moyenera. Zimakakamiza zizolowezi zabwino popanda wogwiritsa ntchito kumverera kuti walangidwa.

Kuchita Mwachangu ndi Moyo Wautali

Eco-innovation sikuti imangotengera zomwe zimatuluka. Zimatengera zomwe zimapita ku makina komanso nthawi yayitali bwanji. Kugwiritsa ntchito kwa Kobelco zitsulo zolimba kwambiri muzithunzi zawo zazikulu za X si nkhani yatsopano, koma tanthauzo lake la chilengedwe ndilo. Cholimba, chopepuka chimatanthawuza kuti mutha kukwaniritsa kulimba komweko ndi zinthu zochepa. Pa moyo wa makinawo—kuchokera kukupanga kupita ku zonyamulira kupita ku zobwezerezedwanso—zimene zimakhala ndi mphamvu zambiri.

Ndimaganiza za undercarriage. Pazofukula zazing'ono, makamaka m'zombo zobwereka, izi ndizovala zazikulu. Kuyang'ana kwa Kobelco pamatcheni osindikizidwa komanso opaka mafuta sikungogwira ntchito bwino. Zimachepetsa kwambiri kukangana kwamkati ndi kuvala. Ma track omwe amatenga maola 2,000 m'malo mwa maola 1,500 amatanthawuza kuti zida zochepa zomwe zimadyedwa, zinyalala zocheperako, komanso nthawi yochepa kwa kasitomala. Ndiko kulimba, ngati kosasangalatsa, kusinthika kwachilengedwe. Ndi mu mafuta.

Filosofi iyi imafikira ku mgwirizano wamagulu ogulitsa. Kwa magawo ndi chithandizo chanthawi yayitali, kugwira ntchito ndi wothandizira wodalirika ndikofunikira. Kampani ngati Malingaliro a kampani Shandong Pioneer Engineering Machinery Co., Ltd (https://www.sdpioneer.com), yomwe yakhala ikugwira ntchito zamakina kuyambira 2004 ndikutumiza kunja padziko lonse lapansi, imamvetsetsa momwe moyo umakhalira. Adzipangira mbiri, monga tanenera m'mbuyo mwawo, pakukhulupirira ndi kuyamikiridwa ndi makasitomala m'malo ngati US, Canada, ndi Australia. Kwa mwiniwake wa zida, kukhala ndi mwayi wopeza chithandizo chokhazikika, chodalirika chamsika kuchokera kwa abwenzi odziwa zambiri kumatalikitsa moyo wogwira ntchito wa makinawo, omwe mwina ndi njira yokhazikika yokhazikika - kusunga chuma chamtengo wapatali kwa zaka zambiri.

The Noise Factor: Kutulutsa Kochepa Kwambiri

Kutulutsa kumawonekera pa pepala lokhazikika. Phokoso limamveka. Kugwira ntchito m'mapulojekiti odzaza nyumba kapena kugwetsa m'nyumba, makina opanda phokoso sangokhala aulemu; nthawi zambiri zimakhala kusiyana pakati pa kupeza ntchito ndi ayi. Kobelco amayang'ana kwambiri pakuchepetsa phokoso-kudzera m'chipinda cha injini, ma curve okongoletsedwa bwino, komanso kusokoneza kwa hydraulic - ndikuyankha mwachindunji pakumizidwa kwa malamulo akumatauni.

Ndikukumbukira ndikugwiritsa ntchito 13SR pa polojekiti ya kumbuyo kumalo osamva phokoso. Kusiyanitsa poyerekeza ndi chitsanzo cha mpikisano wa kukula kwake kunali komveka. Sizinali chabe za mlingo wa decibel; unali khalidwe la mawu. Kulira kocheperako kochokera ku ma hydraulics, kung'ung'udza kocheperako. Izi tiyeni tiyambepo kale ndikumaliza pambuyo pake popanda kudandaula. Ndilo luso la eco lomwe limamasulira mwachindunji ku zokolola ndi maubale ammudzi.

Izi zikugwirizana ndi luso. Phokoso lambiri limabwera chifukwa chosagwira ntchito bwino—kugwedezeka kwa mizere ya ma hydraulic, kunjenjemera kochokera ku kusalongosoka bwino kwa chigawocho. Chifukwa chake, pothamangitsa makina opanda phokoso, nthawi zambiri amapanga imodzi yabwino kwambiri. Ndi chizungulire chokongola. Chovuta ndikuchita izi popanda kusokoneza kuziziritsa, ndipamene mafanizi awo ozizira okonzedwanso, osinthasintha-liwiro amabwera. Amangoyendayenda mofulumira momwe amafunikira, akudula phokoso ndi mphamvu ya parasitic kuchokera ku injini.

Real-World Trade-offs and Operator Buy-in

Palibe zatsopano zomwe zili zaulere. Kuvuta kwa machitidwe ophatikizikawa kungatanthauze zokwera mtengo zam'tsogolo komanso njira yophunzirira yamakanika. Zida zowunikira ndizopadera kwambiri. Apa ndi pomwe mphira umakumana ndi msewu. Kukonzekera kwachilengedwe komwe kumapulumutsa $ 5,000 mumafuta koma kumawononga $ 7,000 yochulukirapo pakukonzanso kwapadera pa moyo wake ndikutayika konse.

Kuchokera pa zomwe ndaziwona, Kobelco wayendetsa bwino izi poyang'ana pa kudalirika ndi kuphweka mkati mwa zovuta. Magawo owongolera zamagetsi (ECUs) ndi olimba. Mapangidwe a sensor ndi omveka. Kwaukadaulo wautumiki, ndizotheka. Ndipo chofunikira kwambiri, apangitsa kuti zopindulitsa ziwonekere kwa wogwiritsa ntchito. Ma cab ambiri tsopano ali ndi mawonekedwe osavuta amafuta. Wogwiritsa ntchito ataona kuti akuwotcha malita 2.1 pa ola m'malo mwa 2.8, amapeza. Iwo amakhala gawo la yankho.

Mayeso omaliza ndi mtengo wotsalira. Makina odziwika bwino pakugwiritsa ntchito mafuta komanso kulimba kwake amakhala ndi mtengo wake bwino. M'misika yomwe mtengo wa umwini umawunikidwa, kusintha kwazinthu zachilengedwezi kumasintha kuchoka pakukhala wabwino kukhala nawo mbali yofunika kwambiri yazachuma yamakina. Si zachifundo; ndi bizinesi yanzeru. Ndipo ndicho chifukwa chake zinthuzi, kuchokera ku injini zophatikizira kupita kumayendedwe osindikizidwa, zasuntha kuchokera m'mphepete kupita pachimake cha momwe wopanga wamkulu ngati Kobelco amapangira mini excavator lero. Cholinga sikumanga makina obiriwira. Ndiko kupanga makina abwinoko, okwera mtengo kwambiri omwe, monga chotulukapo, amakhala obiriwira. Ndi filosofi yomwe mungagwiritse ntchito.
