Kev ntsuas qhov kub thiab txias qhov tseeb ntawm lub tshuab ziab khaub ncaws kub yuav tsum muaj ntau- ntsuas qhov ntsuas kub thiab cov ntaub ntawv kaw nyob rau hauv kev ua haujlwm ruaj khov. Lub hauv paus tseem ceeb yog txhawm rau txheeb xyuas seb qhov kub hloov pauv li cas hauv 60-80℃kev khiav haujlwm tsawg dua lossis sib npaug li ± 3 degree, thiab cov cuab yeej zoo yuav tsum tswj nws hauv ± 1 degree.
1. Kev Xeem Npaj thiab Ib puag ncig yuav tsum tau ua
Cov cuab yeej xeem:
Infrared tus pas ntsuas kub (qhov tseeb ± 0.5 degree)
Hu rau tus pas ntsuas kub thermocouple (tuaj yeem tso rau hauv qhov hluav taws xob cua qhov hluav taws xob)
Cov ntaub ntawv logger (yeem, rau kev soj ntsuam tas li)
Ib puag ncig tej yam kev mob:
Nyob ruaj khov hauv chav tsev kub (20-25 degree), tsis txhob muaj cua convection.
Cov khoom siv preheated rau 10 feeb kom ncav cuag thermal equilibrium.
2. Kev sim cov kauj ruam thiab cov txheej txheem ua haujlwm
(1) Teem Lub Hom Phiaj Kub
Teem lub tshuab ziab khaub ncaws (xws li rab phom cua kub lossis qhov cub) rau 70℃(tus nqi nruab nrab ntawm tus nqi)
Tos 5-10 feeb kom txog thaum lub teeb pom kev zoo stabilizes
(2) Multi-Point Temperature Measurement Verification
Kev ntsuas kub ntawm qhov hluav taws xob: Siv lub ntsuas kub infrared los tsom rau ntawm qhov chaw ntawm qhov hluav taws xob thiab sau qhov ntsuas kub txhua feeb rau 10 feeb
Hauv - Kev Ntsuas Kub Kub: Ntxig lub ntsuas kub ntsuas rau hauv lub raj dej simulation raj (ntev Ntau dua lossis sib npaug li 30cm) thiab ntsuas qhov ntsuas huab cua tiag tiag xa mus rau hauv pwm
Rov Ua Kev Xeem: Rov ua cov txheej txheem saum toj no ntawm 60℃thiab 80℃feem
(3) Kev txheeb xyuas cov ntaub ntawv
Xam qhov siab tshaj qhov sib txawv (qhov kub siab tshaj - qhov kub qis tshaj) ntawm 10 nyeem
Kev Txiav Txim Siab:
Tsim nyog: Kev hloov pauv tsawg dua lossis sib npaug rau ± 3 degree
Zoo heev: Kev hloov pauv tsawg dua lossis sib npaug rau ± 1℃(kev ua tau zoo ntawm PID cov khoom siv ntsuas kub)
3. Kev txiav txim siab thiab qib zoo
Indicator Tsim Nyog Standard High-end Standard
Kev ntsuas kub hloov pauv tsawg dua lossis sib npaug rau ± 3℃Tsawg dua lossis sib npaug rau ± 1 degree
Teb ceev: ncav cuag tus nqi hauv 5 feeb; ncav cuag tus nqi hauv 3 feeb
Kev ruaj ntseg: Tsis txhob dhia tam sim ntawd rau 10 feeb sib law liag; Kev hloov pauv yooj yim yam tsis muaj kev hloov pauv sai
Cov Lus Cim Tseem Ceeb: Cov kub hloov pauv ntau dhau lossis nquag rov pib ua cua sov tuaj yeem ua rau O- nplhaib laus lossis micro- tawg hauv cov hlau. Ib txwm siv cov khoom siv nrog kev tswj qhov kub thiab txias.
