Yog lawm, recalibration feem ntau yuav tsum tau tom qab hloov cov kub khiav kub sensing hlau. Txawm hais tias qhov ntsuas kub ntawm cov xov hlau tshiab ua raws li cov qauv kev qhia tshwj xeeb xws li PT100, me ntsis raug yuam kev ntawm ib tus neeg sensors (xws li qhov sib txawv ntawm qhov rhiab heev thiab cov yam ntxwv teb) tuaj yeem ua rau qhov kub thiab txias deviations thiab cuam tshuam qhov ntsuas kub yog siv ncaj qha. Txhawm rau kom ntseeg tau tias qhov system ruaj khov thiab cov txheej txheem txhaj tshuaj molding zoo sib xws, kev rov ua dua yog pom zoo tom qab hloov.
I. Yog vim li cas thiaj li yuav tsum tau recalibration
Sensor variability: Txawm tias ntawm PT100 platinum tiv thaiv tus pas ntsuas kub, cov khoom sib txawv lossis cov npe yuav muaj qhov sib txawv me ntsis ntawm qhov kub thiab txias dua li 0 degree. Piv txwv li, ntawm 200 degree, ob qhov tsim nyog PT100 sensors yuav txawv ntawm 1-2 degree, uas tsis muaj qhov tsis zoo hauv siab -precision txhaj molding.
Cov kev xav tau sib xws: Cov neeg ua haujlwm kub khiav feem ntau ua rau qhov kub thiab txias thiab PID parameter optimization raws li cov ntaub ntawv keeb kwm los ntawm tus thawj sensor. Tom qab hloov lub sensor, tus thawj calibration tsis yog tag nrho siv thiab recalibration yog tsim nyog.
Zam kev hloov pauv ntawm cov txheej txheem: Cov cheeb tsam tsis sib xws yuav muaj qhov kub thiab txias ntau dhau, ua rau cov khoom siv degradation, tsis txaus sau, thiab muaj kev ntxhov siab ntxiv, cuam tshuam ncaj qha rau cov khoom zoo.
II. Canibration yuav hla
Calibration tuaj yeem hla hauv cov xwm txheej hauv qab no:
Thaum hloov qhov kub thiab txias sensor nrog tib tus qauv thiab batch, thiab ntau lawm tsis tas yuav tsum tau kub tswj qhov tseeb (piv txwv li, nyob rau hauv ± 5 degree);
Thaum multimeter ntsuas thiab kev sim ua haujlwm xyuas kom paub tseeb tias qhov kev hloov pauv ntawm cov qub thiab tshiab sensors qhia tau zoo ib yam, thiab tus maub los qhia qhov kub thiab txias uas phim tus nqi tiag tiag.
Txawm li cas los xij, rau kev molding precision (piv txwv li, optical Cheebtsam, khoom siv kho mob), yuav tsum tau calibration yog tseem pom zoo kom ua kom raug.
III. Cov lus pom zoo ua haujlwm Calibration:
Ib puag ncig tej yam kev mob: Calibration yuav tsum tau ua nyob rau hauv ib tug tsis muaj cua, plua plav- ib puag ncig dawb nrog kub thiab av noo. Recalibration yuav tsum tau yog tias qhov kub thiab txias hloov siab tshaj 5 degree.
Txoj kev pom zoo
Point Temperature Calibration: Muab qhov ntsuas kub rau hauv qhov chaw paub qhov kub thiab txias (piv txwv li, 0℃rau cov dej khov- dej sib tov, 100℃rau cov dej kub npau npau), thiab kho tus maub los offset kom paub meej cov txiaj ntsig zoo ib yam.
Tus Txheej Txheem Kev Sib Piv Txoj Kev: Siv lub siab- ntsuas qhov ntsuas qhov ntsuas kub kom ua tau raws li cov qauv teeb liab, simulating qhov tseem ceeb ntawm qhov sib txawv ntawm qhov kub thiab txias los xyuas thiab kho qhov kev tswj xyuas cov lus teb.
Ua raws li-Kev Tshawb Fawb:
Ntsuas qhov kub ntawm lub nozzle siv lub ntsuas kub infrared thiab sib piv nrog cov kev nyeem ntawv.
Ua kev sim molding los soj ntsuam cov dej ntws sib xws thiab cov khoom seem stability.
Tswv yim: Qee qhov siab -kawg kub khiav tshuab txhawb nqa "ib- nyem calibration" muaj nuj nqi, uas tuaj yeem ua tiav ntau- taw tes ntsuas los ntawm software, txhim kho kev ua haujlwm.
