Koj puas tau xav paub yuav ua li cas lub tsheb cement tuaj yeem nqa cov cement txaus los sau lub tsev? Hauv tsab ntawv blog no, peb yuav tshawb xyuas cov khoom ntawm lub tsheb cement thiab cov txheej txheem ntawm kev ua pob zeb. Tsis tas li ntawd, peb yuav tham txog qee qhov kev siv ntawm pob zeb.
Lub tsheb cement kuj hu ua a qhob tov khoom tsheb, nqa cov cement hmoov, xuab zeb, gravel, thiab dej los ua pob zeb. Cov pob zeb sib xyaw hauv lub tsheb thauj khoom thaum nws txav mus rau qhov chaw ua haujlwm. Feem ntau cov tsheb thauj khoom cement muaj lub nruas tig los sib tov cov ntaub ntawv.
Txhawm rau tsim pob zeb, thawj cov khoom xyaw yog cov cement hmoov. Cement yog tsim los ntawm cua sov limestone thiab av nplaum. Cov txheej txheem no, hu ua calcination, ua rau lub clinker uas yog hauv av rau hauv cov hmoov. Cov hmoov no hu ua cement.
Cov khoom xyaw tom ntej yog dej, tov nrog cov cement los tsim cov slurry. Tus nqi ntawm cov dej ntxiv txiav txim siab lub pob zeb lub zog, vim tias cov dej ntau dua ua rau cov pob zeb tsis muaj zog. Xuab zeb, ib qho zoo sib sau ua ke uas pab ua kom tiav qhov chaw nruab nrab ntawm cov cement thiab gravel, yog cov khoom xyaw tom ntej.
Cov khoom xyaw kawg yog gravel, ib coarse aggregate uas muab lub pob zeb lub zog thiab lub hauv paus rau cov cement thiab xuab zeb. Lub zog ntawm cov pob zeb yog nyob ntawm qhov piv ntawm cov cement, xuab zeb, gravel, thiab dej. Qhov feem ntau piv yog ib feem cement, ob seem xuab zeb, peb seem gravel, thiab plaub ntu dej.
Lub tsheb cement ntxiv cov hmoov cement rau lub nruas kom sib tov cov khoom xyaw, ua raws li dej. Xuab zeb thiab gravel ntxiv tom ntej. Thaum tag nrho cov khoom xyaw nyob rau hauv lub nruas, lub tsheb sib xyaw ua ke. Kev sib xyaw kom paub meej txawm tias faib cov khoom xyaw. Tom qab sib tov, lub pob zeb yog npaj rau kev siv. Pob zeb yog siv rau ntau lub hom phiaj, nrog rau kev taug kev, kev tsav tsheb, thiab hauv paus.

Yuav Ua Li Cas Lawv Sau Lub Cement Truck?
Cov txheej txheem ntawm kev ntim cov cement tsheb yog qhov yooj yim. Lub tsheb thauj khoom rov qab mus rau qhov chaw thau khoom ntawm tib theem, yog li tsis tas yuav muaj qhov ramp. Ib lub chute yog txuas rau sab ntawm lub tsheb thauj khoom, uas txuas mus los ntawm qhov chaw thau khoom rau hauv lub tsheb. Cov cement yog poured rau hauv chute, thiab lub tov khoom ntawm lub tsheb tiv thaiv nws los ntawm hardening. Tom qab tag nrho, lub chute raug tshem tawm, thiab lub tsheb tau tsav mus.
Dab tsi yog Sab hauv Cement Truck?
Lub tsheb cement muaj ntau qhov chaw, qhov tseem ceeb tshaj plaws yog lub nruas. Nws yog qhov chaw uas cov pob zeb sib xyaw, feem ntau yog ua los ntawm cov hlau lossis txhuas, thiab tig los ntawm kev sib xyaw cov khoom xyaw. Lub cav yog lwm qhov tseem ceeb ntawm lub hauv ntej, muab lub zog tsheb thauj khoom. Lub cab, qhov twg tus neeg tsav tsheb zaum thiab tswj tau nyob, yog nyob tom qab ntawm lub tsheb.
Yuav Ua Li Cas Cement Truck Spin?
cov spinning motion ntawm cov cement tsheb khaws cov sib tov kom tas li, tiv thaiv hardening thiab kom ntseeg tau tias sib tov. Kev sib hloov kuj tso cov khoom sib tov rau hauv lub tsheb thauj khoom lub thawv. Lub cev muaj zog sib cais ua rau lub nruas sib hloov, thaum lub koob ntawm cov hniav lossis cov ntsia hlau siv los ntawm tib lub cev muaj zog ua kom cov sib sau ua ke, dej, thiab cov cement nyob rau hauv tas li ntawd. Tus neeg teb xov tooj tswj qhov ceev thiab cov dej ntxiv rau qhov sib tov.
Qhov txawv ntawm Cement Truck thiab Concrete Truck yog dab tsi?
Ntau tus ntawm peb tau pom lub tsheb thauj khoom cement ua rau txoj kev loj, tab sis tsis yog txhua tus nkag siab tias nws nqa dab tsi. Cement tsuas yog ib feem ntawm pob zeb. Pob zeb muaj xws li cov cement, dej, xuab zeb, thiab aggregate (gravel, pob zeb, los yog crushed pob zeb). Cement yog qhov khi txhua yam ua ke. Nws hardens thiab muab lub zog rau cov khoom kawg.
Cov tsheb thauj khoom cement thauj cov cement hauv daim ntawv qhuav. Thaum lawv mus txog ntawm qhov chaw ua haujlwm, dej ntxiv, thiab cov khoom sib tov feem ntau yog agitated los yog tov ua ntej yuav muab nchuav rau hauv cov ntaub ntawv los tsim kev taug kev, hauv paus, lossis lwm yam qauv. Cov dej ua kom cov cement, ua rau nws pib khi txhua yam ua ke.
Cov tsheb thauj khoom ua ke nqa cov pob zeb uas tau npaj ua ntej uas tau muab sib xyaw ntawm cov nroj tsuag. Nws muaj tag nrho cov khoom xyaw tsim nyog, suav nrog dej thiab cement. Txhua yam uas yuav tsum tau yog nchuav rau hauv cov ntawv.
Pouring pob zeb yog ib lub sij hawm-sensitive txheej txheem txij li thaum lub sij hawm cov dej hits cov cement; nws pib tawv sai sai. Tias yog vim li cas thiaj li muaj koj cov ntaub ntawv teeb tsa thiab kev txhawb nqa hauv qhov chaw ua ntej lub tsheb tuaj txog qhov tseem ceeb. Yog li ntawd, lwm zaus koj pom lub tsheb "cement" ya los ntawm, nco ntsoov nws nqa pob zeb!
