Yuav ua li cas Watt Density cuam tshuam rau kev ua tau zoo ntawm 10000mm Ntxiv -Long Cartridge rhaub
Lub tshuab cua sov muaj kev vam khom rau kev ua tau zoo ntawm cov tshuab cua sov, thiab ib qho tseem ceeb tshaj plaws uas txiav txim siab lawv cov kev ua tau zoo thiab kev ua haujlwm ntev yog watt ntom. Rau 10000mm ntxiv- ntev lub tshuab tso cua sov, watt ceev yuav tseem ceeb dua -vim lawv qhov ntev ntev, qhov tsis zoo watt ntom tuaj yeem ua rau cua sov tsis sib xws, overheating, lossis tsis ua kom ncav cuag qhov kub thiab txias, txhua yam tuaj yeem cuam tshuam kev tsim khoom thiab nce nqi. Ntau cov tuam txhab lag luam saib xyuas qhov cuam tshuam ntawm watt ntom ntom, xav tias txhua lub tshuab cua sov uas muaj qhov ntev yuav ua haujlwm, tab sis qhov no yog qhov yuam kev kim heev uas tuaj yeem zam tau yooj yim nrog kev nkag siab yooj yim ntawm watt ntom ntom ua haujlwm li cas.
Lub tshuab rhaub cartridge yog lub tshuab cua sov uas tsim los rau kev ntxig rau hauv qhov ua ntej -drilled qhov, hloov hluav taws xob hluav taws xob mus rau lub zog hluav taws xob los ntawm cov coil resistive. Lub 10000mm ntxiv- ntev cartridge rhaub yog tsim los npog cov cua kub loj, ua rau nws zoo tagnrho rau cov ntawv thov xws li yas extrusion, ntev - yeeb nkab cua sov, thiab loj pwm tsim. Watt ceev, txhais tau tias yog lub zog ntawm ib cheeb tsam ntawm cheeb tsam (feem ntau ntsuas hauv W / cm²), ncaj qha cuam tshuam sai npaum li cas lub rhaub tuaj yeem ncav cuag qhov kub ntawm lub hom phiaj, nws faib cov cua sov li cas, thiab nws yuav kav ntev npaum li cas.
Qhov tseeb, kev sib raug zoo ntawm watt ntom ntom thiab cov khoom siv hluav taws xob ntawm lub tshuab hluav taws xob yog qhov yooj yim: ntau dua watt ceev txhais tau tias muaj cua sov ntau dua nyob rau hauv ib cheeb tsam, ua rau lub sij hawm cua sov sai dua. Txawm li cas los xij, qhov no tsis tau txhais hais tias ntau dua watt ceev yog ib txwm zoo dua. For 10000mm extra-long cartridge heaters, which have a large surface area, excessive watt density can cause localized hot spots-areas where the temperature is significantly higher than the surrounding surface. Cov chaw kub no tuaj yeem ua rau lub tshuab cua sov ua kom puas, ua rau cov khoom siv rwb thaiv tsev puas, thiab txawm tias cov khoom siv los yog cov khoom ua kom sov. Ntawm qhov tod tes, qhov tsawg watt ceev yuav ua rau cua sov qeeb, tsis muaj peev xwm tswj tau qhov kub thiab txias, thiab siv tsis muaj zog.
Rau feem ntau cov ntawv thov kev lag luam siv 10000mm ntxiv -ntev cartridge rhaub, watt ceev ntawm 5-7 W / cm² yog qhov zoo tshaj plaws. Qhov ntau yam no sib npaug ntawm cov cua kub ceev thiab kev nyab xeeb, kom ntseeg tau tias lub tshuab cua sov tuaj yeem ncav cuag qhov xav tau kub sai yam tsis tsim qhov kub. According to experience, this watt density range is particularly effective for plastic extrusion, where uniform heating of the extruder barrel is critical to melting plastic raw materials consistently. watt ceev ntawm 5-6 W / cm² yog qhov zoo tagnrho rau cov ntawv thov kub mus rau nruab nrab, thaum 6-7 W / cm² ua haujlwm zoo tshaj plaws rau siab -cov ntawv siv kub xws li cov pwm loj cua sov lossis cov yeeb nkab cua sov.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias watt ceev yuav tsum tau sib txawv raws li daim ntawv thov thiab cov khoom raug rhuab. Piv txwv li, cov ntaub ntawv uas muaj thermal conductivity, xws li hlau, yuav tsum tau ib tug ntau dua watt ceev kom ntseeg tau tias cua sov yog kis tau sai thiab uniformly. Nyob rau hauv sib piv, cov ntaub ntawv uas tsis muaj thermal conductivity, xws li yas los yog roj hmab, yuav tsum tau ib tug tsawg watt ceev kom tsis txhob overheating nto thaum lub sab hauv tseem txias. Rau 10000mm ntxiv- ntev cartridge tso cua sov siv hauv kev ua zaub mov, qhov qis dua watt ceev (ze li 5 W / cm²) raug pom zoo kom tiv thaiv kom tsis txhob hlawv lossis hlawv cov khoom noj.
Lwm qhov yuav tsum tau xav txog yog qhov chaw ua haujlwm. Nyob rau hauv corrosive lossis siab - ib puag ncig cov av noo, qhov tsawg dua watt ceev yuav zoo dua, vim tias cov cua sov ntau dhau tuaj yeem ua kom corrosion ntawm lub rhaub lub tsho. Piv txwv li, nyob rau hauv qhuav, siab - qhov kub thiab txias ib puag ncig, ib tug ntau dua watt ceev (txog 7 W / cm²) tej zaum yuav tsim nyog los tswj qhov kub thiab txias. Raws li kev paub dhau los, kho cov watt ntom ntom raws li ib puag ncig tuaj yeem txuas ntxiv lub neej kev pab cuam ntawm 10000mm ntxiv - ntev cartridge rhaub kom txog li 40%.
Ntau lub tuam txhab ua qhov yuam kev ntawm kev xaiv 10000mm ntxiv - ntev cartridge rhaub raws li qhov ntev thiab wattage, yam tsis xav txog watt ntom. Piv txwv li, lub rhaub 10000mm nrog lub siab wattage tab sis tsis tshua muaj watt ceev yuav tsis muab cua sov txaus rau ib chav tsev kom tau raws li cov kev xav tau ntawm daim ntawv thov, thaum lub rhaub nrog siab watt ceev tab sis ntev tsis txaus yuav tsis npog tag nrho cov cua sov. Tus yuam sij yog xam qhov xav tau watt ntom ntom raws li daim ntawv thov qhov kub thiab txias, cov khoom siv cua sov, thiab qhov chaw ua haujlwm.
Txhawm rau txiav txim siab qhov watt ntom ntom rau 10000mm ntxiv -ntev cartridge rhaub, pib los ntawm kev txheeb xyuas qhov kub thiab txias ntawm cov khoom siv lossis cov khoom siv ua kom sov. Tom qab ntawd, xav txog lub rhaub dej ntawm qhov chaw (xws li raws li nws txoj kab uas hla thiab qhov ntev) thiab xaiv qhov watt ntom ntom uas yuav muab cov cua sov txaus kom ncav cuag lub hom phiaj kub yam tsis muaj cua sov. Nws tseem yog ib qho tseem ceeb uas yuav tau sab laj nrog cov chaw tsim khoom siv lub tshuab cua sov, raws li cov ntaub ntawv sib txawv (xws li Incoloy lossis stainless hlau) tuaj yeem tswj cov watt sib txawv.
Txhawm rau ua kom tiav, watt ntom ntom yog qhov tseem ceeb hauv kev ua haujlwm thiab kev ua haujlwm ntev ntawm 10000mm ntxiv - ntev cartridge rhaub. Qhov zoo tshaj plaws watt ntom ntom ntawm 5-7 W / cm² ua haujlwm rau feem ntau cov ntawv thov kev lag luam, tab sis kev hloov kho yuav xav tau raws li cov khoom siv, qhov kub thiab txias, thiab qhov chaw ua haujlwm. Kev nkag siab thiab xaiv txoj cai watt ntom ntom kom ua kom muaj cua sov zoo, sib faib qhov kub thiab txias, thiab lub neej ntev ntawm lub rhaub. Different industrial applications have unique watt density needs, and professional scheme design can help calculate the exact watt density required for optimal performance.
