Tab sis cov khoom ntim sab hauv zoo yog qhov nyuaj rau kev lav phib xaub siv sijhawm ntev.

2.Qhov sib txawv hauv kev ua tiav cov thermocouple ua tiav vim qhov sib txawv ntawm cov khoom siv

(1) Thermal drift thiab anti-aging yam ntxwv txawv

Cov hmoov rwb thaiv tsev sab hauv ntawm cov thermocouples uas tsim los ntawm cov khoom siv lub tshuab nqus tsev nqus cov kab ntau lawm yog ntom thiab impurity -dawb, tsis muaj cua qhov thiab cov impurities conductive. Qhov ntsuas kub ntawm qhov nce ntxiv yog tsawg dua 0.4℃tom qab txuas ntxiv 720 teev ntawm 380℃qhov kub thiab txias kev laus, thiab kev pabcuam lub neej nyob rau hauv peb-hloov kub kub ntau lawm tuaj yeem ncav cuag 6 lub hlis. High-kawg hauv tsev tag nrho- tsis siv neeg puv cov khoom siv drift increment yog 0.6 ~ 0.9℃tom qab tib txoj kev laus, thiab kev pab cuam lub neej yog li 4 lub hlis nyob rau hauv tib lub load; qis-kawg ib nrab- tsis siv neeg puv generic thermocouples drift increment tshaj 1.8℃tom qab 72 teev kub kub ci, thiab pom tseeb ntsuas qhov sib txawv tshwm sim nyob rau hauv 1 lub hlis ntawm kev tsim khoom loj, calibration thiab hloov tau nquag.

(2) Qhov sib txawv ntawm rwb thaiv tsev tsis kam thiab noo noo tsis kam

Lub rwb thaiv tsev tsis kam ntawm cov thermocouples tuaj txawv teb chaws yog ruaj khov siab dua 1200MΩ hauv qab 500VDC megohmmeter kuaj ntawm 380℃qhov kub thiab txias, siab -kawg hauv tsev puv- cov khoom tsis siv neeg puv yog khaws cia ntawm 600 ~ 900MΩ, thiab qis dua -}kawg semi-tsis siv neeg ntim khoom tom qab 20 mΩ, thiab qis dua luv- Circuit Court txhaum yog ib qho yooj yim tshwm sim tom qab absorbing rhiav huab cua. Lub tshuab nqus tsev nqus ntim cov qauv ntawm cov khoom siv txawv teb tuaj yeem tiv thaiv kev nkag mus rau sab nraud ntawm cov dej vapor thiab corrosive yas volatile gas, thiab cov hmoov rwb thaiv tsev sab hauv yuav tsis raug crushed tom qab rov qab txias thiab kub; domestic semi{12}} tsis siv neeg xoob ntim cov khoom lag luam muaj ntau qhov sib txawv ntawm cov huab cua, thiab cov pa ya raws thiab cov kua qaub sai sai nkag mus rau hauv cov hlab ntsws kom kis tau cov hmoov rwb thaiv tsev, ua kom lub rwb thaiv tsev tsis ua haujlwm.

(3) Qhov sib txawv ntawm cov lus teb ceev thiab thermal lag

Qhov sib txawv ntom ntom -dawb magnesium oxide hmoov muaj qhov sib xws thiab ua kom muaj cua sov hloov pauv, thiab lub sijhawm teb ntawm 1.0mm grounded sojntsuam thermocouple yog tsawg dua 1.2s; lub sij hawm teb ntawm siab -kawg hauv tsev tag nrho- tsis siv neeg puv cov khoom yog 1.8 ~ 2.5s vim tias muaj cov pa me me hauv cov hmoov; qhov qis-kawg ib nrab- tsis siv neeg puv cov hmoov av muaj qhov kub hnyiab loj, cov lus teb lag luam yog ntau tshaj 4s, uas tsis tuaj yeem ua tau raws li kev tswj xyuas qhov tseeb ntawm ultra- voj voog ceev nyias- phab ntsa pwm, thiab nws yooj yim los tsim cov rooj vag solidification thiab cov yas scorching tsis xws luag vim qeeb PID fais fab hloov.

3. Kev taw qhia kev xaiv cov khoom kom haum rau kev xav tau ntau lawm

1. Kev kho mob cleanroom multi- kab noj hniav pwm, lub zog tshiab tsheb core structural part pwm, thiab 24 xuab moos peb -hloov nruam siab -kub PPS/LCP cov kab ntau lawm: Tsom rau cov khoom siv thermocouple nrog cov khoom xa tuaj puv - teeb lub tshuab nqus tsev ntim cov kab ntau lawm, txawm hais tias tus nqi pib ua haujlwm ntev {6} cov nqi kho mob siab, thiab tus nqi siab tshaj downtime poob yog qhov qis tshaj plaws, thiab cov ntaub ntawv calibration ruaj khov ua tau raws li kev soj ntsuam nruj heev ntawm cov neeg siv khoom OEM siab tshaj -.

2. Cov khoom siv hauv tsev thiab cov khoom siv hluav taws xob dav dav, sib cuam tshuam loj hauv ob qhov kev hloov pauv, molding tsis yog -corrosive PP/ABS ntawm qhov kub nruab nrab Xaiv siab-kawg cov tuam txhab tsim khoom siv nrog cov tshuab nqus tsev puv puv, cov khoom ua tau zoo tuaj yeem ncav cuag ntau dua 90% ntawm cov qauv tuaj txawv teb chaws, cov nqi khoom seem raug txo los ntawm ze li ntawm ib nrab, kev tswj cov khoom lag luam thiab kev ruaj ntseg.

3. Rau kev tsim cov khoom ua si qis-tsis muaj tseeb- cov ntaub ntawv corrosive, luv- sim cov qauv pwm, thiab ib zaug - hloov qis- ntim cov khoom ua si thiab ntim pwm, qis - tus nqi generic thermocouples tuaj yeem siv ib ntus nrog cov khoom siv hluav taws xob tsis siv neeg hloov pauv mus rau lub voj voog luv luv -, lub hli, thiab qhov ntsuas kub txhua hnub ntawm kev soj ntsuam xyuas yuav tsum tau ua kom muaj zog kom tsis txhob muaj cov khoom tsis zoo uas tshwm sim los ntawm kev nrawm nrawm.

4. Cov txheej txheem tsim khoom lag luam tshawb xyuas cov khoom rau pwm Hoobkas

Thaum kuaj xyuas cov khoom siv thermocouple, nws yog qhov yuav tsum tau mus xyuas qhov kev cob qhia ntau lawm los xyuas cov qauv ntawm lub tshuab nqus tsev ntim khoom, ntsuas qhov ntsuas lub tshuab nqus tsev ntawm qhov chaw, xyuas cov magnesium oxide hmoov kom qhuav thiab purification txheej txheem cov ntaub ntawv, thiab tau txais online rwb thaiv tsev tiv thaiv batch xeem ntawv qhia txog cov khoom tiav. Rau cov neeg muag khoom thov kom siv cov kab xa tuaj txawv teb chaws, tshawb xyuas cov khoom qub ntawm cov nqi yuav khoom thiab cov ntaub ntawv ua haujlwm ntawm cov khoom siv; rau cov khoom siv hauv tsev, coj cov qauv ntawm cov khoom tiav rau 72-teev siab-kub aging drift test thiab siab -kub rwb thaiv tsev ntsuas ntsuas, tsuas yog cov ntaub ntawv ntsuas ua tau raws li tus qauv, koj tuaj yeem ua tiav nrog kev koom tes nrog kev yuav khoom, txhawm rau zam kev yuav khoom qis qis ntim cov thermocouples nrog rau qhov muaj kev pheej hmoo loj.
