DY-300 Milling Machines: Qhov Kev daws teeb meem zoo tshaj plaws rau kev kho dua tshiab ntawm Asphalt Surface

Qhov Ceev Ceev ntawm Kev Kho Dua Asphalt Zoo: Cov Teeb Meem Hauv Kev Lag Luam​

Ua ntej yuav tham txog lub peev xwm ntawm DY-300, nws yog ib qho tseem ceeb kom nkag siab txog cov teeb meem uas cov pab pawg saib xyuas asphalt thoob ntiaj teb ntsib. Raws li International Road Federation (IRF), ntau tshaj 40% ntawm cov kev asphalt thoob ntiaj teb xav tau kev kho dua tshiab hauv 5-7 xyoo ntawm kev tsim kho, tab sis cov txheej txheem ib txwm muaj teeb meem ua kom tau raws li qhov kev thov no. Piv txwv li, kev sib tsoo tes - vam khom cov cuab yeej tuav tes - tsuas yog tuaj yeem ua tiav 20-30 square meters ntawm qhov chaw ib teev, thaum cov tshuab sib tsoo qub feem ntau tawm cov chaw tsis sib xws uas xav tau kev du ntxiv, ua rau lub sijhawm ua haujlwm thiab cov nqi nce ntxiv.

Ntxiv mus, cov khoom pov tseg yog qhov teeb meem loj. Kev kho dua tshiab ib txwm tshem tawm tag nrho cov txheej asphalt (feem ntau 5-10 cm) txawm tias tsuas yog sab saud 1-2 cm puas lawm, ua rau muaj 30-40% ntawm cov khoom pov tseg uas xaus rau hauv qhov chaw pov tseg. Qhov no tsis yog tsuas yog ua rau cov nqi ib puag ncig nce ntxiv xwb tab sis kuj ua rau cov nuj nqis rau kev tsim cov asphalt tshiab nce ntxiv. Kev kaw txoj kev ua rau qhov teeb meem loj dua: kev kaw ib txoj kab ntawm txoj kev loj uas tibneeg coob coob tuaj yeem ua rau kev tsheb khiav qeeb qeeb.

1,200–3,000 ib teev, raws li American Association of State Highway and Transportation Officials (AASHTO). Cov teeb meem no qhia txog qhov xav tau kev daws teeb meem uas sib npaug ntawm kev ceev, kev raug, thiab kev ruaj khov - raws nraim li lub tshuab DY-300 milling xa tuaj.

Cov Peev Xwm Tseem Ceeb ntawm DY-300: Kev Ua Haujlwm Zoo Tshaj Plaws rau Kev Kho Dua Tshiab​

Lub DY-300 yog tsim los daws cov teeb meem ntawm cov txheej txheem ib txwm muaj los ntawm cov yam ntxwv siab heev uas muab qhov tseem ceeb rau kev ua haujlwm zoo, kev raug, thiab kev yooj yim rau cov neeg siv. Hauv nws lub hauv paus, lub tshuab siv lub tshuab hydraulic siab-torque ua ke nrog lub nruas milling dav 1.8-meter-dav dua li cov nruas 1.2-1.5-meter ntawm feem ntau cov neeg sib tw. Lub nruas dav dua no tso cai rau DY-300 npog txog li 120 square meters ntawm qhov chaw asphalt ib teev, uas yog 40-60% nce ntxiv hauv kev tsim khoom piv rau cov tshuab milling txheem. Piv txwv li, txoj kev 1-kilometer ntawm ob txoj kab (xav tau 4,000 square meters ntawm milling) tuaj yeem ua tiav hauv 34 teev nrog DY-300, piv rau 50-60 teev nrog cov qauv qub.​

Kev ua kom raug yog lwm yam cim ntawm DY-300. Nruab nrog GPS-guided depth control thiab laser leveling technology, lub tshuab tswj tau qhov milling tob ntawm ±1 hli—qhov tseem ceeb rau kev ua kom tiav qhov kev npaj ntawm qhov chaw ua ntej resurfacing. Qhov no tshem tawm qhov xav tau kev du, txo cov kauj ruam project thiab txo cov khoom pov tseg. Lub nruas milling nws tus kheej yog nruab nrog 80 tungsten carbide hniav, teeb tsa ua tus qauv kauv kom ntseeg tau tias txiav tas li thiab tiv thaiv kev tawg ntawm qhov chaw. Cov hniav no kuj hloov tau, nrog lub neej siv tas li 50-80 teev—ob npaug ntev npaum li cov hniav hlau txheem—txo cov nqi kho thiab lub sijhawm tsis ua haujlwm.​

Kev paub ntawm tus neeg siv tsis raug saib tsis taus. Lub DY-300 muaj lub cab-over tsim nrog ergonomic tswj, 10-nti touchscreen zaub, thiab 360-degree pom kev - txo qhov nkees ntawm tus neeg teb xov tooj thaum lub sijhawm ua haujlwm ntev. Lub tshuab kuj tseem me me (6.2 meters ntev, 2.5 meters dav) thiab muaj lub vojvoog tig ntawm 4.8 meters, ua rau nws haum rau cov cheeb tsam hauv nroog nrog txoj kev nqaim lossis cov ces kaum nqaim. Rau cov haujlwm loj, DY-300 tuaj yeem ua ke nrog lub tshuab thauj khoom tshwj xeeb uas thauj cov asphalt milled ncaj qha rau hauv cov tsheb thauj khoom, tshem tawm qhov xav tau kev khaws cia nruab nrab thiab ua kom cov haujlwm yooj yim dua.

Cov Kev Siv Hauv Lub Ntiaj Teb Tiag: Ua pov thawj tias muaj txiaj ntsig zoo hauv kev nqis tes ua​

Kev ua tau zoo ntawm DY-300 tsis yog tsuas yog raws li kev xav xwb—nws tau raug lees paub hauv ntau qhov project kho dua tshiab uas muaj npe nrov thoob plaws teb chaws. Xyoo 2023, lub nroog Berlin, lub teb chaws Yelemees, tau siv 12 lub tshuab DY-300 los kho dua 15 mais ntawm txoj kev hauv nroog ua ntej qhov kev tshwm sim thoob ntiaj teb loj. Qhov project no xav tau kev txiav 60,000 square meters ntawm qhov chaw asphalt nrog qhov tob ntawm 2 cm (los daws qhov teeb meem rutting thiab tawg). Siv DY-300's GPS technology, pab neeg tau ua tiav qhov tob sib npaug thoob plaws 98% ntawm thaj chaw, txo cov khoom pov tseg los ntawm 35% piv rau lawv qhov project xyoo 2021 (uas siv cov tshuab txiav qub). Qhov project tau ua tiav hauv 28 hnub—ob lub lis piam ua ntej lub sijhawm teem tseg—txo kev cuam tshuam tsheb hauv plawv nroog.​

Hauv Tebchaws Meskas, Lub Tsev Haujlwm Saib Xyuas Kev Thauj Mus Los hauv Texas (TxDOT) tau siv cov tshuab DY-300 los kho ib ntu 20-kilometer ntawm Interstate 35, uas tau raug kev puas tsuaj loj heev thiab kev sib tsoo vim muaj tsheb thauj khoom hnyav. Lub tshuab DY-300 lub zog siab tau tso cai rau nws los tsoo cov asphalt tawv (uas tau nias rau ntau tshaj 10 xyoo) yam tsis tau qeeb qeeb, thaum lub tshuab conveyor tau ua rau kev thauj khoom ntawm cov khoom siv milled tas mus li. TxDOT tau tshaj tawm tias muaj kev nce 42% ntawm kev tsim khoom txhua hnub piv rau lawv cov khoom siv yav dhau los, thiab cov asphalt milled tau rov ua dua tshiab ntawm qhov chaw (sib xyaw nrog cov pob zeb tshiab) los tsim 30% ntawm cov asphalt tshiab siv rau kev rov ua dua tshiab - txiav cov nqi khoom siv los ntawm $ 120,000.

Cov rooj plaub no qhia txog qhov zoo tseem ceeb ntawm DY-300: nws lub peev xwm los hloov kho rau ntau yam kev xav tau ntawm cov haujlwm, txij li txoj kev hauv nroog mus rau txoj kev loj, thiab xa cov txiaj ntsig zoo sib xws hauv kev ceev, kev raug, thiab kev txuag nqi.

Kev Ruaj Ntseg: Ua Raws Li Lub Hom Phiaj Ib puag ncig Thoob Ntiaj Teb​

Nyob rau lub caij nyoog uas muaj kev tsom mus rau kev ruaj khov ntxiv, DY-300 sawv tawm rau nws txoj kev tsim uas zoo rau ib puag ncig. Raws li tau hais lawm, lub tshuab txiav cov khoom siv precision txo cov khoom pov tseg los ntawm 30-40% piv rau cov txheej txheem ib txwm muaj. Ntxiv mus, cov asphalt milled (hu ua reclaimed asphalt pavement, lossis RAP) tsis yog tsuas yog pov tseg xwb - nws tuaj yeem rov ua dua tshiab rau hauv cov asphalt sib xyaw tshiab. Cov txheej txheem txiav DY-300 tsim RAP nrog qhov loj me sib npaug, ua rau nws yooj yim dua los koom ua ke rau hauv cov sib xyaw tshiab (txog li 50% RAP hauv qee kis), txo qhov xav tau rau cov pob zeb aggregates thiab bitumen.

Kev siv hluav taws xob zoo yog lwm lub zog. Lub DY-300 siv lub twj hydraulic uas hloov pauv tau uas kho qhov tso zis hluav taws xob raws li qhov hnyav, es tsis txhob khiav ntawm lub peev xwm tag nrho tas li. Qhov no txo ​​​​​​kev siv roj los ntawm 15-20% (piv rau cov twj tso kua mis hloov pauv tas li), txo cov pa roj carbon los ntawm kwv yees li 0.8 tons ib 100 teev ntawm kev ua haujlwm. Lub tshuab kuj ua tau raws li Euro Stage V thiab EPA Tier 4 Final emissions standards, kom ntseeg tau tias ua raws li cov cai ib puag ncig thoob ntiaj teb.

Xaus Lus: DY-300 ua tus Catalyst rau Smarter Asphalt Rehabilitation​

Lub tshuab txiav DY-300 tsis yog tsuas yog ib yam khoom siv xwb—nws yog ib qho kev daws teeb meem uas daws tau cov teeb meem tseem ceeb ntawm kev kho dua tshiab ntawm cov asphalt: kev ua haujlwm tsis zoo, kev tsis meej, kev pov tseg, thiab kev cuam tshuam rau ib puag ncig. Los ntawm kev sib xyaw ua ke ntawm kev tsim khoom siab (120 square meters ib teev), kev ua haujlwm raug zoo heev (± 1 hli kev tswj qhov tob), thiab kev tsim qauv ruaj khov (txo cov khib nyiab thiab cov pa phem), DY-300 ua rau cov koom haum thauj mus los thiab cov neeg cog lus ua tiav cov haujlwm sai dua, ntawm tus nqi qis dua, thiab nrog qhov chaw tsawg kawg nkaus rau ib puag ncig.

Thaum lub ntiaj teb cov kev tsim kho vaj tse laus zuj zus thiab qhov kev thov kom tau txais kev saib xyuas zoo zuj zus, DY-300 sawv cev rau yav tom ntej ntawm kev kho asphalt - yav tom ntej uas kev kho txoj kev sai, muaj kev nyab xeeb, thiab ruaj khov, ua kom ntseeg tau tias cov tes hauj lwm thauj mus los tseem muaj kev ntseeg siab rau ntau xyoo tom ntej. Rau txhua lub koom haum uas tab tom nrhiav kev txhim kho lawv cov txheej txheem kho asphalt, DY-300 tsis yog tsuas yog kev xaiv xwb - nws yog qhov kev daws teeb meem kawg.
