Xaiv Watt Density rau Dependable Cartridge Heater Performance

Xaiv Watt Density rau Dependable Cartridge Heater Performance
Kev ua tsis tiav thaum ntxov yog feem ntau tshwm sim los ntawm kev xaiv cov khoom cua sov tsuas yog raws li tag nrho cov wattage. Nyob ntawm seb lub zog faib li cas thoob plaws hauv nws thaj chaw, lub tshuab hluav taws xob lub tshuab hluav taws xob ntsuas ntawm ntau pua watts tuaj yeem ua haujlwm tau zoo lossis hlawv sai sai. Qhov sib txawv ntawm qhov kub thiab txias ntawm cov hlau sab hauv thiab sab nraud yog txiav txim siab los ntawm watt ntom ntom, uas yog xam los ntawm kev faib lub zog los ntawm qhov chaw sov. Txawm hais tias cov hlau nyob ib puag ncig tseem nyob ntawm qhov txheej txheem kom zoo, cov hlau khiav kub heev thaum qhov ceev tshaj qhov muaj cua sov- lub dab dej.
Nyob rau hauv qhov chaw soj ntsuam zoo tagnrho, siab - cov tshuab cua kub ceev nrog ze li qhov zoo meej fittings thiab yuam kom txias tuaj yeem ua tiav 15-46 W / cm². Txawm li cas los xij, rau cov khoom siv- hlau cua sov ntawm pwm, tuag, thiab platens, kev ceev faj ntau dua ntawm 5-7 W / cm² tau ua pov thawj tias muaj kev ntseeg siab hauv kev siv niaj hnub. Thaum cov khoom siv muaj cov thermal conductivity tsawg (xws li qee cov hlau tsis muaj steel) lossis thaum lub tshuab cua sov ntev yuav tsum khiav nrog qhov chaw nthuav dav me me, qhov ntom ntom qis dua lub neej ntev dua. Tshwj tsis yog tias tsis muaj qhov yuam kev, huab cua lossis kua immersion daim ntawv thov feem ntau hu rau qhov qis dua.
Watt ceev tuaj yeem xam tau yooj yim los ntawm kev faib tag nrho watts los ntawm π lub sijhawm txoj kab uas hla lub sijhawm rhuab ntev. Txias kawg yuav tsum tsis txhob muab tso rau hauv cov mis; tsuas yog qhov nquag rhuab ib feem ntawm lub cartridge rhaub yuav tsum. Lub bore haum dhau los ua qhov tseem ceeb thaum paub tus lej. Txawm tias qhov sib txawv ntawm 0.1 hli tuaj yeem ua rau muaj kev ntxhov siab ntau ntxiv los ntawm kev nce qhov kub ntawm kaum degrees. Qhov tseeb kev ua haujlwm ceev yog khaws cia ze ntawm tus nqi suav los ntawm cov qhov remed nrog qhov clearance ntawm 0.02-0.05 hli.
Cov teeb meem ceev yog exacerbated los ntawm voltage faults. A 10% tshaj-voltage ua rau kwv yees li 21% ntau lub zog thiab, yog li, ntau dua vim lub zog sib txawv nrog cov square ntawm voltage. Cov tswj nrog SCR cov cai lossis cov khoom ruaj khov- lub xeev hloov pauv qhov kub ntawm qhov viav vias thiab muab kev tiv thaiv ntxiv. Kev nrawm qis-lub zog ci- tawm ua ntej ua haujlwm puv tshem tawm cov av noo ntxiv los ntawm magnesium oxide thiab rov ua kom cov rwb thaiv tsev tiv thaiv, txawm hais tias kev nqus noo noo tseem muaj peev xwm sib txawv.
Kev soj ntsuam teb rov qab qhia tau hais tias cov khoom siv hluav taws xob tso rau hauv cov qhov dej huv huv, tiv thaiv los ntawm kev sib kis, thiab kev ua haujlwm nyob rau hauv qhov tseeb qhov ntom ntom ntev ntev dua li cov uas raug thawb mus rau qhov siab tshaj plaws. Different density targets and, thus, different diameter or length selections are required for distinct process requirements, such as quick recovery in thin moulds against steady-state temperature in big platens. Tsis yog tsuas yog ua kom lub zog loj tshaj plaws xwb, sib piv cov thermal load rau qhov tsim nyog - qhov loj ntawm lub tshuab cua sov ua rau muaj kev ua haujlwm tsis tu ncua thiab kev saib xyuas lub sijhawm.
