I-Kobelco Mini Excavator Eco-Innovations: Ukubuka Kwezinga Eliphansi

Uma uzwa eco-innovations ishaywa eshidini le-mini excavator, kulula ukukucasukela. Ingabe kungenye nje ibhokisi lokumaka lokumaketha, noma ingabe kukhona okushintsha ngempela ngaphansi kwe-hood? Njengoba sengichithe iminyaka kumasayithi lapho le mishini ingamahhashi okusebenza, ngiye ngabona uguquko ukusuka kumamethrikhi wamandla amsulwa ukuya kule nhlanganisela emurkier yokusebenza kahle nokuzibophezela. Indlela ka-Kobelco lapha incane mayelana nesihloko esicwazimulayo nokunye okuningi mayelana nochungechunge lwezinketho zobunjiniyela ezenziwe ngamabomu, kwesinye isikhathi ezicashile, ezihlanganisayo. Akukhona ngokuba luhlaza kakhulu ngenxa yakho; imayelana nokuxazulula izinkinga zesizinda sangempela—izindleko zikaphethiloli, imingcele yomsindo, ubuhlungu bekhanda lokunakekela—ngezixazululo ezenzekayo zibe nonyawo olulula. Yilokho umehluko obalulekile emhlabathini.

Ukuqopha i-Eco ku-Powerplant

Inhliziyo yengxoxo ihlale iyinjini. U-Kobelco akazange avele awise injini ehambisana ne-Tier 4 Final futhi ayibize ngosuku. Ukuqamba okusha kwangempela, kumamodeli afana ne-17SR noma 35SR, kusekuhlanganisweni. Kungumshado wedizili ehlanzekile ene-hydraulic system engalwi nayo. Ngikhumbula ngisebenzisa imishini emidala lapho wawungezwa khona ukuthi ama-hydraulics edla uphethiloli. Amasistimu amasha asebenzisa lokho abavame ukukubiza ngokuthi i-total hydraulic optimization. Empeleni, lokhu kusho ukuthi iphampu ayigcini nje ngokulahla ukugeleza okweqile phezu kwevalvu yokukhulula; ifanisa okukhiphayo nesidingo se-joystick. Awubasi udizili ukushisa uwoyela we-hydraulic ngokungadingekile.

Kunomphumela osebenzayo lapha ongasitholi isikhathi somoya esanele: ukuphathwa kokushisa. Isistimu esebenza kahle kakhulu ikhiqiza ukushisa okuncane okulahlwayo. Esizeni esiminyene sasemadolobheni noma ngaphakathi kwesakhiwo, lokho kuyinto enkulu. Iphakheji yokupholisa ingaba yincane, umshini usebenza ngokupholile, futhi uthola ukucindezeleka okushisayo okuncane ezintweni. Ngike ngabona amapayipi nama-seal ahlala isikhathi eside emishinini lapho ama-hydraulics engahlali esesimweni sokwethuka. Lokho ukuqamba okusha kwe-eco kufika ekugcineni ngqo—isikhathi esincane sokuphumula, izingxenye ezimbalwa.

Kodwa akuphelele. Ukushintshela kulezi zinjini ezithuthukisiwe kwaletha izinkinga ezijwayelekile zamazinyo. Ekuqaleni, abanye osonkontileka engibaziyo bebezixwaye izinhlelo eziyinkimbinkimbi zokwelashwa. Ukwesaba i-DPF evalekile ngoMsombuluko ekuseni kuyiqiniso. Impendulo ka-Kobelco, ebonakala isebenza, bekuwukuklama imijikelezo yokuvuselela engenzi lutho futhi ehlanganisa idatha yomshini ukuze azise opharetha ngokushesha. Akubona ubuwula, kodwa kukhombisa ukuthi bebecabanga ngomfana osekhunjini, hhayi nje umjikelezo wokuhlola ukukhishwa kwekhabhoni.

I-Idle Logic kanye Nenganekwane Yokuhlala Kuvuliwe

Lokhu kungase kubonakale kukuncane, kodwa ukuvalwa kwenjini okuzenzakalelayo kungenye yalezo zici eziveza ukuthi ubani ngempela obekusayithi. Ukusetha okuzenzakalelayo emishinini eminingi kunolaka kakhulu—iyavala ngemva kwemizuzu emihlanu yokungasebenzi. Esizeni esimatasa, leyo yindlela enhle yokucasula u-opharetha wakho futhi uguge isiqalisi sakho. Amasistimu ka-Kobelco ajwayele ukulungiseka kakhulu noma, kwezinye izimo, ahlakaniphe. Bangakwazi ukufaka izinga lokushisa likawoyela we-hydraulic noma i-voltage yebhethri. Umgomo awukona ukuvala ngenxa yalokho; ukunciphisa ukungcola kukaphethiloli ngesikhathi sokuphumula sangempela, njengalapho sekhefu elide lasemini noma ukulinda ukulayishwa kweloli.

Ukuhlolwa kwangempela kwakusemsebenzini wezinsiza. Sasine-25SR-2 emsebenzini wokufaka amapayipi lapho umshini wawuzoma kodwa usebenzisa isekethe yesando ngezikhathi ezithile. I-logic endala kungenzeka ukuthi ivale injini phakathi kokuqhuma. Uhlelo lukaKobelco lwalubonakala lubona ukuthi isifunda esisizayo sasihlomile futhi samiswa. Lokho ubunjiniyela obucabangayo. Yonga ilitha likaphethiloli ngosuku, kodwa kuzo zonke izimoto, lokho kunengqondo. Okubaluleke nakakhulu, akuphazamisi isigqi somsebenzi.

Lapho abanye abakhiqizi bevele bengeze inkinobho ye-eco-mode, i-Kobelco ivamise ukuyibhaka ku-logic yokulawula. Awunakho ukukhetha ukungasebenzi kahle ngaso sonke isikhathi. Isistimu ye-hydraulic ishintshela esimweni sokugeleza okuphansi kanye nokucindezela okuphezulu lapho kungenzeka khona, okuvame ukuba yilokho okufunayo ukuze umbe ngokuqondile. Iphoqa imikhuba emihle ngaphandle kokuthi u-opharetha azizwe ejezisiwe.

Ukusebenza Kwezinto Ezinhle Nokuphila Isikhathi Eside

I-Eco-innovation ayiyona nje into ephuma ekuphelelweni. Kumayelana nokuthi yini engena emshinini nokuthi ihlala isikhathi esingakanani. Ukusebenzisa kuka-Kobelco insimbi eqine kakhulu ku-mainframe yabo emise okuka-X akuyona indaba entsha, kodwa umphumela wayo wemvelo uwukuthi. Uhlaka oluqinile, olulula lusho ukuthi ungakwazi ukuzuza ukuqina okufanayo ngezinto ezincane. Ngesikhathi somjikelezo wokuphila womshini—kusuka kokukhiqiza kuya ekuthuthweni kuya ekugcineni ekugayweni kabusha—lokho kunomthelela okhulayo.

Ngicabanga nge-undercarriage. Kuma-mini excavators, ikakhulukazi emikhumbi eqashisayo, lokhu kuyindawo enkulu yokugqoka. Ukugxila kuka-Kobelco kumaketango ethrekhi avaliwe nagcotshiwe akukona nje ukusebenza kahle. Inciphisa kakhulu ukungqubuzana nokuguga kwangaphakathi. Iqoqo lamathrekhi athatha amahora angu-2,000 esikhundleni samahora angu-1,500 lisho izinto zokusetshenziswa ezimbalwa ezisetshenzisiwe, udoti omncane okhiqizwayo, kanye nesikhathi esincane sokuphumula sekhasimende. Lokho kuyi-eco-innovation eqinile, uma ingathandeki. Isemafutheni.

Le filosofi idlulela ebudlelwaneni bochungechunge lokuhlinzeka. Ezingxenyeni nokusekelwa kwesikhathi eside, ukusebenza nomphakeli onokwethenjelwa kubalulekile. Inkampani efana I-Shandong Pioneer Engineering Machinery Co., Ltd (https://www.sdpioneer.com), ebilokhu isendaweni yemishini yobunjiniyela kusukela ngo-2004 futhi ithekelisa emhlabeni jikelele, iyakuqonda lokhu kubuka komjikelezo wempilo. Bazakhele udumo, njengoba kuphawulwe ngemuva kwabo, ekuthembekeni nasekubongeni okuvela kumakhasimende ezindaweni ezifana ne-US, Canada, ne-Australia. Kumnikazi wemishini, ukufinyelela ekusekelweni kwemakethe yangemuva okuhlala isikhathi eside, okuthembekile okuvela kozakwethu abanolwazi kwandisa impilo yokusebenza yomshini, okungenzeka ukuthi iwuhlobo lokugcina lokusimama—ukugcina impahla yekhwalithi ingaphandle kwe-scrapyard iminyaka ngaphezulu.

I-Noise Factor: I-Underrated Emission

Ukukhishwa kuyabonakala eshidini elicacisiwe. Kuzwakala umsindo. Ukusebenza kumaphrojekthi okufakwa kwezindlu zokuhlala noma ukubhidlizwa kwangaphakathi, umshini othulile awuyona nje inhlonipho; kuvame ukuhluka phakathi kokuthola umsebenzi nokungawutholi. Ukugxila kuka-Kobelco ekwehliseni umsindo—ngokufaka injini, amajika efeni athuthukisiwe, kanye nokuxubha amanzi—kuyimpendulo eqondile yokuqinisa imithetho yasemadolobheni.

Ngikhumbula ngisebenzisa i-13SR kuphrojekthi yasemuva endaweni engezwani nomsindo. Umehluko uma kuqhathaniswa nemodeli yesimbangi yosayizi ofanayo wawubonakala. Kwakungekhona nje mayelana nezinga le-decibel; kwakuyikhwalithi yomsindo. Ukukhala okuncane kwe-high-frequency kusuka ku-hydraulics, ngaphezulu kwe-hum ephansi. Lokhu ake siqale kusenesikhathi futhi siqede kamuva ngaphandle kwezikhalo. Lokho kuyi-eco-innovation ehumusha ngokuqondile ekukhiqizeni nasebudlelwaneni bomphakathi.

Lokhu kuhlotshaniswa nokusebenza kahle. Umsindo omningi uvela ekungasebenzini kahle—inxushunxushu emigqeni yokudonsa amanzi, ukudlidliza okuvela ekuqondaneni kabi kwengxenye. Ngakho-ke, ngokujaha umshini othule, ngokuvamile ngokwemvelo bakha osebenza kahle kakhudlwana. Kuyindilinga elungile. Inselele ukwenza lokhu ngaphandle kokubeka engcupheni ukupholisa, okuyilapho abalandeli babo bokupholisa abaklanywe kabusha, abashintshashintshayo befika khona. Baphenduka ngokushesha njengoba kudingeka, ukunqamula umsindo namandla e-parasitic adonsa enjinini.

I-Real-World Trade-offs kanye ne-Operator Buy-in

Akukho okusha mahhala. Ubunkimbinkimbi balezi zinhlelo ezihlanganisiwe bungasho izindleko eziphezulu zangaphambili kanye nejika lokufunda elikhuphukayo lomakhenikha. Amathuluzi okuxilonga akhethekile kakhulu. Yilapho irabha ihlangana khona nomgwaqo. Ukwakhiwa kwe-eco-innovation okonga u-$5,000 kuphethiloli kodwa kubiza u-$7,000 ngaphezulu ekulungiseni okukhethekile empilweni yawo kuwukulahlekelwa inetha.

Kusukela kulokho engikubonile, u-Kobelco uye waphatha le bhalansi ngokugxila ekuthembekeni nasekululani ngaphakathi kobunzima. Amayunithi okulawula ama-elekthronikhi (ECUs) aqinile. Izakhiwo zezinzwa zinengqondo. Ngobuchwepheshe besevisi, iyalawuleka. Futhi okubaluleke kakhulu, benze izinzuzo zabonakala ku-opharetha. Amakhabhi amaningi manje anezibonisi ezilula zokusetshenziswa kukaphethiloli. Uma osebenza ekwazi ukubona ukuthi bashisa amalitha angu-2.1 ngehora esikhundleni sika-2.8, bayayithola. Baba yingxenye yesixazululo.

Ukuhlolwa kokugcina yinani eliyinsalela. Umshini owaziwa ngokusebenza kahle kukaphethiloli nokuqina ubamba inani lawo kangcono. Ezimakethe lapho izindleko ziphelele zobunikazi zicutshungulwa khona, lezi zinguquko ze-eco-innovations zisuka ekubeni into enhle ukuba zibe yingxenye ebalulekile yesiphakamiso sezimali somshini. Akuyona isisa; kuyibhizinisi elihlakaniphile. Futhi yingakho lezi zici, kusukela ekuhlanganisweni kwenjini kuya kumathrekhi avaliwe, zisuke endaweni ezizungezile zaya emnyombweni wokuthi umkhiqizi obucayi njengo-Kobelco udizayina kanjani i-excavator encane namuhla. Umgomo awukona ukwakha umshini oluhlaza. Okokwakha umshini ongcono, owongayo, okuthi, njengomkhiqizo, ube luhlaza. Leyo yifilosofi ongasebenza ngayo.
