Kev pom zoo tag nrho cov sij hawm ntsuas rau qhov ntsuas kub qhov tseeb ntawm lub tshuab ziab khaub ncaws kub yog 15-20 feeb, suav nrog cov khoom siv preheating, ntsuas kub ntau qhov ntsuas, thiab cov ntaub ntawv kaw, kom ntseeg tau tias qhov kub hloov pauv hauv 60-80℃kev khiav hauj lwm ntau yog qhov tseeb thiab txhim khu kev qha.
1. Kev faib sijhawm rau kev sim ua theem

Khoom siv Preheating |
5-10 feeb |
Tso cai rau lub tshuab ziab kom ncav cuag thermal sib npaug thiab qhov ntsuas kub kom ruaj khov. |
|
Teem kub thiab tos kom ruaj khov |
2-3 feeb |
Tos kom qhov ntsuas kub kom ruaj khov tom qab txhua qhov kev hloov pauv ntawm lub hom phiaj kub (piv txwv li, 60 degree, 70 degree, 80 degree). |
|
Kev ntsuas kub tsis tu ncua thiab kev kaw cia |
10 feeb |
Cov ntaub ntawv ntsuas kub txhua feeb, rau tag nrho ntawm 10 cov ntaub ntawv, siv los txheeb xyuas qhov sib txawv. |
Tag Nrho Lub Sijhawm Piav Qhia: Kev ntsuas qhov ntsuas kub ib zaug yuav siv sijhawm li 15 feeb. Yog tias muaj ntau qhov ntsuas kub yuav tsum tau kuaj (60 degree, 70 degree, 80℃pom zoo), tag nrho lub sijhawm yog kwv yees li 45-60 feeb, tso cai rau kev ntsuas kev ntsuas kub ntawm kev ua haujlwm.
2. Yam tseem ceeb cuam tshuam rau lub sijhawm xeem
Cov Khoom Siv: Portable kub cua phom cua sov sai sai (mus txog qhov teeb tsa tus nqi li ntawm 3 feeb), thaum lub qhov cub kub tsis tu ncua qeeb (yuav tsum tau ntau tshaj 10 feeb).
Ambient Temperature: Kub kub los yog muaj zog convection nyob rau hauv lub rhiav yuav ncua lub sij hawm thermal equilibrium.
Multi-Point Verification: Siv dual- txoj kev ntsuas nrog lub ntsuas kub infrared thiab cov ntsuas kub ntsuas ntsuas ntsuas qhov ntsuas qhov tseeb tab sis nce sijhawm me ntsis.
3. Test Pass/Fail Criteria
Qhov kub thiab txias Fluctuation Tsawg dua lossis sib npaug li ± 3 degree: Qhov no yog tus qauv dhau los / tsis ua haujlwm, haum rau niaj hnub tsim.
Siab - Cov Khoom Siv Zoo Hloov Pauv Tsawg dua lossis sib npaug li ± 1 degree: Muaj peev xwm tswj tau qhov kub thiab txias PID, haum rau precision pwm kom qhuav.
Teb ceev: ncav cuag qhov kub thiab txias li ntawm 3-5 feeb yog qhov zoo tagnrho.
Kev Pom Zoo: Ib lub tuam txhab hauv Wuhan tau ua tiav xaiv Bolaisheng thiab Sumei cov cuab yeej nrog kev tswj xyuas qhov kub thiab txias los ntawm cov txheej txheem txheej txheem ntawm "5 feeb ntawm preheating + 10 feeb ntawm kev ntsuas kub tsis tu ncua," ncua lub neej ntawm pwm cov ntsaws ruaj ruaj los ntawm 40%.
