Kev daws teeb meem: Vim li cas 400℃Cartridge Heater Tuag?

Yog tias lub tshuab hluav taws xob 400℃tso tseg tsis ua haujlwm hauv nruab nrab ntawm kev tsim khoom, thawj qhov uas tib neeg feem ntau ua yog rub ib qho khoom seem thiab txuas ntxiv mus. Tab sis kev hloov pauv yam tsis paub tias yog vim li cas yuav luag qee yam kom muaj cov cua sov hauv qab no tuag sai sai. Siv ib txoj hauv kev los daws cov teeb meem uas suav nrog kev nrhiav pom cov cim qhia, ua qhov kev ntsuam xyuas hluav taws xob, saib ib puag ncig, thiab tshuaj xyuas qhov teeb tsa hloov pauv txhua qhov tsis ua haujlwm rau hauv cov ntaub ntawv tseem ceeb. Yog tias ua tau zoo, nws tuaj yeem txwv tsis pub rov tshwm sim dua thiab coj lub neej nruab nrab ntawm cov cua sov no rov qab mus rau tag nrho 12,000-15,000 teev lawv tau tsim rau.
Pib nrog Kev Tshawb Fawb Txog Kev Pom Zoo
Tshem tawm lub cua sov uas tawg thiab saib nws hauv lub teeb ci. Hnyav scaling los yog mottled zaj sawv discoloration ntawm lub sheath yog ib tug paub tseeb hais tias ntawm overheating, uas feem ntau yog tshwm sim los ntawm tsis zoo bore hu los yog ib tug huab cua sib txawv loj tshaj 0.10 hli. Yuav kom ua tau li ntawd, lub rhaub yuav tsum tau khiav 100-150℃kub nyob rau sab hauv, uas ua rau lub NiCr 80/20 hlau thiab MgO rwb thaiv tsev puas. Cov pob khaus lossis hlwv hauv ib cheeb tsam txhais tau hais tias muaj ntau dhau ntawm cov khoom siv, uas tuaj yeem tshwm sim los ntawm lub voj voog luv luv lossis lub teeb ntawm cov dej noo. Yog tias tsuas yog ib qho kawg nkaus xwb, qhov txhaum yog yuav luag feem ntau nrog kev teeb tsa (xws li yog tias qhov seem tsuas yog tso rau hauv ib feem lossis qhov cua sov tau nthuav tawm). Nqa cov duab ntawm txhua yam ua ntej koj ntxuav nws; cov duab no yuav yog koj cov ntaub ntawv ntawm qhov ua yuam kev.

Saib kom muaj kuab paug nyob hauv ib puag ncig
Nyob rau ntawm 400 degree, noo noo thiab roj yog tuag taus yam tsis muaj suab. Tshawb xyuas cov hlau lead kawg rau oily wicking, carbonized residue, los yog dawb powdery deposits. Thaum lub hwj chim qhib, cov kua uas tau nyob ze ntawm qhov kev txiav tawm yuav hloov mus rau hauv chav. Qhov no rhuav tshem MgO thiab ua rau kev nkag mus rau hluav taws xob kom ntws mus rau hauv lub hnab. Txawm tias cov cua sov uas tsis tau siv tuaj yeem nqus dej noo los ntawm huab cua hauv qhov chaw ntub dej lossis thaum cov khoom ntxuav. Qhov no tuaj yeem txo qis kev tiv thaiv los ntawm ntau dua 1,000 MΩ mus rau tsawg dua 1 MΩ thaum hmo ntuj. Yog tias koj cov txheej txheem suav nrog cov neeg tso tawm, nco ntsoov tias lawv qhuav tag ua ntej qhov kawg tso. Cov neeg ua haujlwm ntub dej yog qhov ua rau muaj qhov ua txhaum hauv av hauv cov yas molding.
Ua Kev Ntsuas Hluav Taws Xob
Rau peb qhov kev kuaj xyuas yooj yim, siv digital multimeter thiab megohmmeter:
1. Qhov kev tiv thaiv ntawm ob lub hwj chim coj yog infinite, uas txhais tau hais tias lub Circuit Court yog qhib (cov hlau tau tawg los ntawm tshav kub los yog oxidation).
2. Kev tiv thaiv ntawm txhua cov hlau lead thiab cov ntaub qhwv: Yog tias qhov kev nyeem ntawv tsawg dua 1 MΩ, muaj qhov ua txhaum hauv av (MgO tawg vim yog dej los yog av).
3. Txheeb xyuas qhov ntsuas tsis kam tiv thaiv tus nqi npe, uas yuav tsum nyob hauv 5% ntawm tus nqi npe. Qhov loj dip txhais tau hais tias lub lem yog luv, thiab ib tug loj nce txhais tau hais tias lub kauj yog tawg.

Cov kev ntsuam xyuas no tsuas yog siv 60 vib nas this thiab pom 90% ntawm qhov ua tsis tiav tam sim ntawd.
Saib seb cov khoom siv hluav taws xob thiab kev tswj ua haujlwm li cas
Txoj kev ceev tshaj plaws los tua lub rhaub yog hloov qhov voltage. Ib chav 240 V ntawm 208 V ua haujlwm tsis muaj zog tab sis kav ntev dua. Ib chav 277 V lossis ib qho nrog spikes, ntawm qhov tod tes, rhuav tshem nws tus kheej hauv feeb. Kev caij tsheb kauj vab nrawm (tig rau thiab tawm txhua ob peb vib nas this) ua rau thermal shock uas hnav tawm cov hlau tsis kam. Xyuas kom tseeb tias koj PID maub los teeb tsa yog lawm. Tus nqi ramp yuav tsum siv tsawg kawg 30 mus rau 60 vib nas this kom ncav cuag lub zog tag nrho. Yog tias tus maub los yos hav zoov ± 15℃lossis ntau dua, nws txuas ntxiv nthuav dav thiab cog lus rau lub rhaub. Teeb tsa cov ntaub ntawv kaw lus rau ib qho kev hloov pauv los sau qhov tseeb qhov hluav taws xob, lub voj voog tus nqi, thiab qhov ntsuas kub.
Xyuas cov ntaub ntawv installation thiab daim ntawv thov
Nug cov lus nug tseem ceeb: - Puas yog txoj kab uas hla ntawm 0.05 txog 0.10 hli ntawm qhov xav tau? - Puas yog tag nrho cov cua sov ntev haum rau txhua txoj hauv kev, lossis yog ib feem ntawm nws "qhuav- tua" hauv huab cua? - Puas yog watt ntom ntom (5–8 W / cm² rau cov polymers thiab 9–12 W / cm² rau hlau)? - Puas yog sheath alloy ntawm lub tshuab cua sov rau ib puag ncig (304, 316L, lossis 321)?

Muaj ntau yam teeb meem los ntawm ib lub qhov uas tsis tau remed tom qab lub qhov kawg ntawm lub rhaub los yog ib chav tsev uas tau shoved rau hauv ib lub qhov me me heev, uas tshem tawm cov oxide txheej thiab ua rau kub kub.
Ua Failure ib yam ntawm yav dhau los
Siv cov duab, sau cov ntawv nyeem tsis kam, ntsuas hluav taws xob, thiab cov ntawv teeb tsa rau txhua qhov tsis ua haujlwm. Yog tias lub rhaub dej tsis tau peb zaug ua ke, feem ntau nws tsis yog lub rhaub; nws yog lub tshuab lossis cov txheej txheem. Qee qhov kev kho mob tas mus li yog hloov mus rau 316L lossis 321 sheaths, ntxiv cov ntsaws ruaj ruaj kom tsis txhob ya raws, txhim kho cov mos- pib tswj, lossis siv cov cua sov nrog ua - hauv cov thermocouples kom tswj tau zoo dua.

Qhov tawg 400℃cartridge rhaub tsis yog $ 30 - $ 80 ib feem; nws yog ib qho cuab yeej kuaj mob uas qhia koj ib yam dab tsi hauv qhov system yuav tsum tau kho. Los ntawm kev siv txoj kev tshawb nrhiav no tsis yog hloov cov chav tsev xwb, cov nroj tsuag uas ua ntej ntawm qhov nkhaus tuaj yeem txo qis siv lub tshuab cua sov los ntawm 50-70%, txiav downtime, thiab ua kom cov kab ntau lawm ua haujlwm zoo tshaj plaws. Tsis txhob hloov lub tshuab hluav taws xob tawg; kho nws lub sijhawm tom ntej. Koj cov peev nyiaj rau kev saib xyuas thiab sijhawm ua haujlwm yuav ua tsaug.
