Lub tsev tsav yog ib qho tseem ceeb ntawm asphalt mixing cog, yog li txawm tias nws tuaj yeem ua haujlwm tau zoo yuav tsum muaj txiaj ntsig zoo kom tsis txhob muaj kev cuam tshuam rau tag nrho asphalt tov cog. Txhawm rau kom ntseeg tau tias lub tsev tsav tsheb hauv asphalt sib xyaw cog yog qhov ua tiav thiab txhim khu kev qha, cov kev saib xyuas hauv qab no yog qhov tseem ceeb.
Thawj qhov uas yuav tsum tau them sai sai rau yog lub universal rotating ib feem ntawm lub drive unit ntawm asphalt mixing cog. Qhov no ib txwm yog ib feem ntawm qhov yuam kev. Txhawm rau txo qhov tshwm sim ntawm qhov tsis zoo, cov roj yuav tsum tau ntxiv rau lub sijhawm, thiab cov hnav yuav tsum tau kuaj xyuas ntau zaus, thiab kho thiab hloov lub sijhawm. Cov neeg siv yuav tsum tau npaj lub universal ncej sib dhos kom tsis txhob cuam tshuam cov txheej txheem ua hauj lwm ntawm tag nrho asphalt mixing cog.

Qhov thib ob, kev huv huv ntawm cov roj hydraulic siv hauv asphalt tov cog yuav tsum tau ua kom ntseeg tau. Tom qab tag nrho, qhov chaw ua haujlwm ntawm cov khoom siv yog qhov hnyav, yog li nws yog qhov tsim nyog los tiv thaiv cov dej phwj tuaj thiab av nkos los ntawm kev nkag mus rau hauv hydraulic system. Cov roj hydraulic tseem yuav tsum tau hloov tsis tu ncua raws li cov kev cai ntawm phau ntawv. Thaum cov dej los yog av nkos tau sib xyaw hauv cov roj hydraulic thaum kuaj xyuas, lub kaw lus hydraulic yuav tsum tau nres tam sim ntawd los ntxuav lub hydraulic system thiab hloov cov roj hydraulic.
Txij li thaum muaj hydraulic system, ntawm chav kawm, ib tug sib piv cov cuab yeej txias kuj yuav tsum tau, uas kuj yog ib qho tseem ceeb ua kom pom tseeb nyob rau hauv tsav system ntawm asphalt mixing cog. Txhawm rau kom ntseeg tau tias nws txoj haujlwm tuaj yeem ua tiav tag nrho, ntawm ib sab, hydraulic roj radiator yuav tsum tau ntxuav tsis tu ncua los tiv thaiv lub radiator los ntawm cov cement; ntawm qhov tod tes, lub tshuab hluav taws xob hluav taws xob hluav taws xob yuav tsum tau kuaj xyuas seb nws puas ua haujlwm ib txwm los tiv thaiv cov roj hydraulic kub dhau ntawm tus qauv.
Feem ntau, ntev li ntev tau cov roj hydraulic ntawm asphalt sib xyaw cog cov cuab yeej tsav tsheb yog khaws cia huv si, feem ntau muaj qee qhov txhaum; tab sis lub neej kev pab cuam txawv ntawm cov chaw tsim khoom rau cov chaw tsim khoom, yog li ua tib zoo saib xyuas nws cov alkalinity thiab hloov nws raws sijhawm.
