Cov piv txwv ntawm kev laus drift nyob rau hauv kub khiav tshuab muaj xws li: ib tug PET preform ntau lawm kab muaj kev sib sau tsis sib xws vim qhov sib txawv ntawm 8℃kub ntawm lub nozzle lub tswv yim; ib tug kho mob connector pwm qhov twg thermocouple drift ua rau insertion/extraction rog kom tshaj specifications; thiab cov kab hluav taws xob kho qhov muag raug kev txom nyem los ntawm kev ntxhov siab sab hauv-induced warping los ntawm cua sov coil degradation. Sib sau ua ke, cov xwm txheej no qhia tau hais tias kev laus zuj zus tuaj yeem nce los ntawm qhov tsis sib xws ntawm qhov kub me me mus rau qhov loj - qhov ua tsis tau zoo.
1.PET Preform Production Line: Xaus-Nozzle kub sib txawv ua rau qhov hnyav hloov pauv
Keeb kwm: Lub chaw tsim khoom ntim dej haus tau siv 8-kab kab noj hniav kub khiav los tsim 500ml PET preforms, ua haujlwm tsis tu ncua rau ntau tshaj 50,000 teev.
Cov tsos mob:
Cov preforms ua los ntawm ob qhov kawg kab noj hniav hnyav 3.2% tsawg dua tus nqi tus qauv, thiab flashing tshwm sim ntau zaus.
Tus tswj qhov kub thiab txias tau qhia tias qhov kub thiab txias hauv txhua cheeb tsam yog qhov qub; Txawm li cas los xij, kev ntsuas ntsuas nrog ntsuas ntsuas ntsuas tau pom tias qhov ntsuas kub ntawm qhov kawg nozzles yog 8.5℃qis dua qhov qhia.
Keeb kwm:
Tus nqi tsis kam ntawm cov cua sov coils tau degraded los ntawm 18%, thiab cov cim qhia ntawm thermocouple tau drifted. Qhov no, ua ke nrog cov pa roj carbon monoxide tsim nyob rau hauv cov kab khiav khiav, ua rau txo cov dej ntws tawm.
Kev daws teeb meem:
Kev kho kom raug suav nrog kev tshem tawm cov pa roj carbon monoxide, hloov cov khoom muaj hnub nyoog, thiab kev siv "Delta 5" kub tswj nyiaj them. Yog li ntawd, qhov sib txawv ntawm qhov kub thiab txias tau nqaim mus rau ± 1.5 degree, thiab tus nqi tawm los ntawm 94% mus rau 99.3%.
2. Kev Kho Mob Connector Pwm: Thermocouple Drift Triggers Assembly Failure
Keeb kwm: Kev tsim khoom koom nrog siab -cov khoom siv hluav taws xob muaj tseeb uas yuav tsum tau muab tso rau thiab tshem tawm kom ruaj khov nyob rau hauv thaj tsam ntawm 0.8 ± 0.1 N.
Cov tsos mob:
Thaum lub caij ntuj no ntau lawm, tus nqi tsis lees paub vim tsis yog - ua raws li kev tso cai / rho tawm tau nce los ntawm 0.2% mus rau 1.8%.
Kev kuaj mob tau qhia tias thaum lub sijhawm ntsuas kub rau qhov kub thib peb yog 280 degree, qhov ntsuas ntsuas qhov tseeb tsuas yog 262 degree.
Keeb kwm:
Lub caij ntev thermal caij tsheb kauj vab tau ua rau lub thermocouple poob calibration, ua rau lub cev tswj qhov kub thiab txias "paub" qhov ntsuas kub tsis raug. Yog li ntawd, lub kaw lus tsis tu ncua tso tawm tag nrho lub zog, uas exacerbated localized carbonization.
Kev daws teeb meem:
Tag nrho cov thermocouples raug hloov, thiab lub kaw lus tau rov ua dua. Los ntawm kev siv Shotscope NX los saib xyuas cov kab nkhaus puv rau txhua qhov kev txhaj tshuaj, qhov teeb meem tau daws tag nrho.
3. Optical Lens Moulding: Internal Stress Warpage Ua los ntawm Heater Band Degradation
Keeb Kwm: Kev tsim cov koob yees duab tsheb siv lub koob yees duab siv siab - cov khoom siv PC pob tshab, yuav tsum muaj kev tswj hwm nruj heev ntawm kev ntxhov siab sab hauv.
Phenomenon:
Tom qab demolding, lub warpage ntawm lub lo ntsiab muag tau nce los ntawm 0.05 hli mus rau 0.18 hli, dhau los ua ke tolerances;
Ntau qhov kev sim los kho qhov ntsuas qhov ntsuas siab tau ua pov thawj tsis muaj txiaj ntsig.
Keeb kwm:
Qhov hluav taws xob tiv thaiv kev sib txawv ntawm plaub lub tshuab hluav taws xob ntau tshaj 12%, uas ua rau muaj kev cuam tshuam ntawm qhov kub thiab txias nyob rau hauv lub tshuab khiav thiab qhov tsis sib xws ntawm cov khoom molten.
Kev daws teeb meem:
Tag nrho cov khoom siv hluav taws xob tau hloov pauv hauv ib pawg, thiab lub kaw lus tau hloov kho mus rau Ultraflow kub khiav system; warpage tswj tau ua tiav rov qab rau hauv 0.04 hli.
Kev Pom Kev Pom Zoo: Tag nrho peb qhov xwm txheej tau tshwm sim los ntawm qhov kub tsis sib xws uas yog " ntsuas tau tab sis sab laug tsis ntsuas," thaum kawg nce mus rau qhov tsis zoo. Tsim kom muaj ib lub tswv yim rau kev ntsuas kub ib ntus thiab kev soj ntsuam cov qauv yog tus yuam sij los tiv thaiv cov teeb meem zoo li no.
