Cov khoom siv raw siv hauv kev tsim kho qhov project sib txawv, yog li lub tsev tsim kho yuav xaiv cov khoom siv raw khoom raws li qhov tseeb. Rau txoj kev paving tam sim no, kev siv cov khoom siv raw ntawm asphalt qhob qib yog feem ntau, thiab cov kev qhia txawv yuav raug siv. Asphalt pob zeb, yog li thaum asphalt mixing cog yog ua, cov ntaub ntawv raw yuav tsum tau muab faib ua raws li cov kev cai, thiaj li ua tau raws li qhov xav tau ntawm kev tsim kho.
Cov pob zeb asphalt tso rau hauv av tuaj yeem muab faib ua cov xim sib txawv ntawm qhov chaw. Qhov no kuj yog ib qho txiaj ntsig ntawm asphalt qhob tom qab ua tiav. Yog li ntawd, asphalt cog muaj cov kev cai nruj heev thiab nws cov kev siv ntau yam kuj dav. , suav nrog kev paving ntawm txoj kev nthuav dav, txoj kev graded, txoj kev hauv nroog, tshav dav hlau, thiab chaw nres nkoj.
Lub asphalt mixing cog muaj xws li lub ntsiab tshuab thiab auxiliary machinery. Thaum siv, nws ua tiav cov haujlwm tseem ceeb xws li kev faib khoom, muab khoom, thiab sib tov. Thaum lub sijhawm ua haujlwm ntawm tag nrho cov txheej txheem ntawm cov cuab yeej siv tshuab, nws ua tiav kev tsim khoom thiab ua tiav ntawm asphalt pob zeb, muab Infrastructure muab cov qauv siab ntawm cov khoom siv raw, yog li asphalt mixing nroj tsuag yog qhov tseem ceeb hauv kev tsim khoom.
Asphalt mixing cog yog hais txog cov cuab yeej ua tiav siv rau kev tsim cov pob zeb asphalt. Nws suav nrog cov khoom xws li ntsuas tshuab, vibrating npo, siv feeder, hmoov conveyor, elevator thiab ntsaws valve. Lub ntsaws valve yog ib tug kaw cov tswv cuab los yog ib tug plunger-shaped rotary valve. Thaum lub sij hawm siv, nws yuav tsum tau tig cuaj caum degrees los ua kom txoj kev qhib lub valve ntsaws tib yam li ntawm lub valve lub cev. Nws kuj tuaj yeem sib cais. ua kom qhib lossis kaw. Thaum siv asphalt sib xyaw cov nroj tsuag, lub ntsaws valve feem ntau yog nyob rau hauv cov duab ntawm lub tog raj kheej los yog lub khob hliav qab.
Lub luag haujlwm ntawm lub valve teb nyob rau hauv asphalt tov khoom cog yog ua kom cov qauv ntawm cov khoom sib zog. Nws yog tsuas yog siv los txiav tawm lossis txuas qhov nruab nrab, thiab tseem tuaj yeem siv los ua kev hloov pauv nruab nrab. Kev khiav hauj lwm ntawm lub teb valve nyob rau hauv asphalt tov khoom cog yog ceev thiab yooj yim. Txawm hais tias nws tau ua haujlwm ntau zaus, yuav tsis muaj teeb meem loj. Tau kawg, lub teb valve kuj muaj ntau lwm yam nta. Nws cov qauv yog yooj yim thiab nws yooj yim los tswj.
