Kev Ua Tsis Zoo & Kev daws teeb meem rau 400℃Cartridge rhaub

Txawm siab -kawg 400℃cartridge heaters ua nrog NiCr 80/20 xaim, siab-purity MgO rwb thaiv tsev, thiab 304/316L stainless hlau sheaths tej zaum yuav tawg ntxov yog tias lawv tsis tau nruab, siv, los yog tswj kom zoo. Hauv cov chaw tsim khoom, 60 mus rau 70 feem pua ​​​​ntawm tag nrho cov cartridge rhaub tsis ua haujlwm yog tshwm sim los ntawm tsib qhov teeb meem tsis tu ncua. Kev txheeb xyuas cov tsos mob, nrhiav cov laj thawj tseem ceeb, thiab kev siv cov phiaj xwm kho tuaj yeem ua rau kev ua haujlwm rov qab mus rau qhov qub nyob rau hauv ob peb feeb thiab ncua lub neej kev pab cuam los ntawm ob peb puas teev mus rau qhov kwv yees 8,000 txog 15,000 teev. Cov lus qhia no yooj yim -- nkag siab txog kev kuaj mob thiab sim-thiab{19}} kho qhov tseeb uas txhua tus kws tshaj lij tuaj yeem siv rau hauv khw hauv khw.

1. Not enough heat or slow warm-up: The heater takes minutes instead of seconds to reach 400 °C, or it never reaches the right temperature. Causes: Low supply voltage, air gaps, surface carbon/oil accumulation, or poor thermal contact (hole tolerance >0.15 hli). Cov no ua ib qho thaiv thaiv thaiv uas ua rau cov hlau sab hauv ua haujlwm nyuaj. Txhawm rau txheeb xyuas qhov tsis raug, siv lub ntsuas qhov ntsuas qhov ntsuas qhov chaw nruab nrab ntawm lub plhaub thiab lub qhov, lub ntsuas kub infrared los nrhiav qhov chaw txias, thiab xyuas qhov hluav taws xob ntawm cov terminals thaum lawv thauj khoom. Txhawm rau kho nws, siv isopropyl cawv thiab txhuam nylon los ntxuav lub qhov thiab lub rhaub. Ream los yog hone lub bore kom tau qhov clearance rov qab mus rau 0.05-0.10 mm. Muab cov txheej nyias nyias ntawm cov khoom siv thermal hloov uas tsis muaj silicone thiab tuaj yeem tswj tau qhov kub thiab txias. Yog tias qhov hluav taws xob tsawg, kho cov khoom siv lossis tau txais cov cuab yeej tshiab uas phim qhov voltage. Kev Tiv Thaiv: Kev ntxuav thiab tshuaj xyuas qhov ib xyoos ib zaug tshem tawm 40% ntawm cov teeb meem no.


2. Cov tsos mob hauv zos overheating thiab Burnout: Tom qab siv ob peb lub lis piam xwb, ib feem glows liab los yog lub rhaub tsis qhib -circuit; lub sheath qhia cov cim ntawm melting los yog discoloration. Cov hauv paus hauv paus: Ntau dhau watt ntom ntom (ntau dua 12 W / cm² hauv qis- cov ntawv thov loj), cuam tshuam cov cua sov dissipation (lub rhaub yog ib feem los yog muab zais rau hauv rwb thaiv tsev), lossis khiav tsis muaj cua sov txaus. Txhawm rau kuaj xyuas, txheeb xyuas qhov ntsuas watt ntom piv rau daim ntawv thov (watts ÷ thaj chaw). Nrhiav cov cheeb tsam kub tshaj 550℃ntawm thermal imaging. Kho: Siv cov watt zoo- qauv ntom ntom lossis ntxiv cov dab dej kub lossis cov fins. Nco ntsoov tias tag nrho cov cua sov ntev nyob rau hauv kev sib cuag nrog cov hlau. Tsis txhob ua haujlwm hauv huab cua lossis nrog qhov tsis zoo. Txhawm rau kom tsis txhob muaj teeb meem, nco ntsoov xyuas kom meej tias lub zog ntom ntom sib phim cov khoom siv: 5-8 W / cm² rau cov yas thiab 9-12 W / cm² rau cov hlau. Tsis tas li ntawd, tsis txhob mus siab dua 80% ntawm qhov ntsuas hluav taws xob thaum thawj qhov kev sim.

3. Cov hluav taws xob luv luv lossis hluav taws xob xau A megohmmeter nthuav tawm cov hluav taws xob tiv thaiv qis dua 1 MΩ, hauv av- txhaum kev mus los, lossis pom meej arcing lossis sparking. Cov laj thawj tseem ceeb yog: Cov dej noo nkag mus rau hauv (los ntawm kev ya raws los yog ntxuav tawm), tawg cov hmoov txhuas los ntawm kev khoov nws ntau dhau, lossis MgO tawg tom qab ntau xyoo ntawm kev caij tsheb kauj vab. Thaum MgO nce mus txog 400 degree, txawm tias cov dej me me ua rau nws ua tau. Kev kuaj mob: Tshawb xyuas cov rwb thaiv tsev tiv thaiv (500 V DC) ntawm cov hlau lead thiab lub plhaub. Xyuas cov hlau lead rau cov pob qij txha los yog cov roj uas tau tsau rau hauv. Kho: Qhov yuav tsum tau hloov tam sim ntawd vim nws tsis tuaj yeem kho kom zoo. Rau qhov chaw ntub dej, siv cov hlau txuas los yog epoxy-cov khoom siv hluav taws xob uas muaj dej noo{12}} pov thawj. Txhawm rau kom tsis txhob muaj teeb meem, khaws cov hlau lead kom deb ntawm tshav kub thiab noo noo, siv stainless hlau braid thiab strain nyem, thiab khaws cov khoom seem hauv lub hnab ntim nrog cov desiccant.

4. Fuses uas tshuab los yog mus txawv tebchaws feem ntau Cov tsos mob: Circuit Court breakers los yog fuses tshuab ntau zaus, feem ntau thaum lub sij hawm pib cua sov. Cov laj thawj tseem ceeb yog vim li cas qhov hluav taws xob tsis raug (220 V rhaub ntawm 380 V muab), lub hauv paus kauj yog luv vim yog MgO tawg, lossis muaj qhov cuam tshuam loj heev thaum lub rhaub pib txias yam tsis muaj qhov muag muag - pib tswj. Kev kuaj mob: Tshawb xyuas daim ntawv qhia lub rhaub kom paub tseeb tias nws muaj qhov ntsuas hluav taws xob zoo thiab ntsuas qhov khoom siv tiag tiag. Txheeb xyuas qhov tsis kam ntawm cov coj (nws yuav tsum nyob hauv 5% ntawm tus nqi npe). Txhim kho: Siv tus qauv voltage. Muab tso rau hauv ib qho khoom siv -lub xeev relay lossis SCR maub los nrog lub mos- pib ramp. Muab tso rau hauv ib lub sij hawm- ncua fuse uas tuaj yeem tswj tau 125% ntawm lub rhaub tam sim no. Sau npe txhua lub tshuab nrog qhov hluav taws xob ntawm lub rhaub, thiab siv cov khoom siv digital ua ntej txhua lub zog{16}} nce.

5. Kev hloov pauv kub thiab cua sov tsis sib xws: PID maub los yos hav zoov ± 15℃lossis ntau dua, thiab qhov zoo ntawm cov khoom hloov pauv ntawm lub voj voog mus rau lub voj voog. Cov hauv paus ntsiab lus yog: ib feem ntawm qhov tso tawm (qhov cua sov tsis ua haujlwm tag nrho), cov hlau tsis sib haum (qhov kub / txias), los yog qhov tsis zoo uas ua rau muaj kev sib cuag. Kev kuaj mob: Thaum lub tshuab cua sov qhib, siv IR tus pas ntsuas kub lossis lub koob yees duab thermal los ntsuas qhov ntev ntawm lub rhaub. Yog tias koj ua tau, ntsuas qhov tsis kam ntawm qhov kawg mus rau qhov kawg thiab los ntawm ntu mus rau ntu. Kho: Muab nws rov qab rau hauv txhua txoj kev; yog tias qhov kev hloov pauv ntau dua 5% raws qhov ntev, hloov nws. Txhawm rau kaw- voj tswj, hloov mus rau lub rhaub nrog J lossis K thermocouple ua hauv. Kom tsis txhob muaj teeb meem, siv lub tshuab cua sov nrog ua- hauv cov sensors hauv cov xwm txheej tseem ceeb thiab tshawb xyuas qhov tob ntawm qhov ntxig nrog lub ntsuas qhov tob tom qab txhua qhov kev hloov pauv.

Kev daws teeb meem ceev rau ntawm -Site

Nrhiav cov cim qhia txog kev puas tsuaj, xws li cov xim tsis zoo lossis cov hlau lead puas.

Test rau voltage thiab kuj.

Test rau rwb thaiv tsev tsis kam.

Xyuas qhov haum thiab txoj kab uas hla ntawm lub bore.

Luam theej duab nrog thermal duab.

Teem caij tiv thaiv kev tiv thaiv peb lub hlis twg: ntxuav lub qhov, nruj cov terminals, thiab sau cov ntaub ntawv rwb thaiv tsev. Cov neeg ua haujlwm yuav tsum tsis txhob siv lub tshuab cua sov yam tsis muaj dej lossis qhov tsis zoo ntawm qhov hluav taws xob. Khaws ntau qhov ntau thiab tsawg hauv 304 thiab 316L sheaths ntawm tes kom koj tuaj yeem hloov tau tam sim ntawd.

Koj tuaj yeem hloov qhov kev daws teeb meem rov ua rau muaj kev ntseeg siab los ntawm kev kawm kho tsib hom kev ua tsis tiav no. Feem ntau cov nroj tsuag uas siv cov txheej txheem no hais tias lawv muaj 50-70% tsawg dua lub tshuab cua sov- cuam tshuam txog kev kaw thiab txo qis cov nqi hloov txhua xyoo. Yog tias muaj teeb meem tseem tshwm sim tom qab cov txheej txheem no, hu rau cov chaw tsim khoom thiab muab lawv qhov voltage, wattage, ib puag ncig, thiab cov duab ntawm qhov tsis ua haujlwm. Lawv feem ntau tuaj yeem pom qhov tsis zoo hauv feeb thiab qhia cov ntaub ntawv zoo dua lossis tsim qauv.

Lub 400℃cartridge rhaub yuav tsum yog qhov txhim khu kev qha tshaj plaws ntawm koj lub tshuab yog tias koj saib xyuas nws. Nws yuav nrog cov kev txawj no los kho tej yam.
