Feem ntau cov ntawv siv lub tshuab rhaub cua sov tsom rau cov hlau pwm cua sov, tab sis tsis yog -cov pwm hlau-xws li yas, roj hmab, thiab pwm pwm- muaj cov cua kub tshwj xeeb uas cov qauv hlau- cov cua sov ua kom zoo tsis tuaj yeem ua tau raws li. Cov pwm uas tsis yog- hlau muaj cov thermal conductivity qis dua, rhiab heev rau overheating, thiab tuaj yeem raug puas tsuaj los ntawm siab -watt-cov cua kub ceev, ua rau cov khoom siv tshwj xeeb cartridge tso cua sov yog qhov tseem ceeb rau cov cua kub zoo, nyab xeeb. Tsab ntawv xov xwm no tshawb txog cov kev hloov pauv thiab kev xaiv rau cov khoom siv hluav taws xob siv rau hauv cov khoom siv tsis yog- hlau pwm cua sov, qhia cov neeg yuav khoom kom xaiv cov cua sov kom raug rau cov yas, roj hmab, thiab cov ntawv thov ntoo.
Tsis yog-cov pwm hlau txawv txawv ntawm cov pwm hlau hauv cov khoom siv thermal, uas cuam tshuam ncaj qha rau kev xaiv lub rhaub. Yas thiab roj hmab pwm muaj cov thermal conductivity tsawg, txhais tau tias cov cua sov hloov maj mam los ntawm cov khoom pwm, thiab siab -watt- kub ceev tuaj yeem hlawv, warp, lossis yaj cov pwm nws tus kheej. Cov pwm ntoo muaj cua sov ntau dua -rhiab heev, nrog rau kev pheej hmoo ntawm charring los yog tawg yog tias raug kub heev. Standard cartridge heaters tsim los rau cov pwm hlau muaj watt ceev thiab ceev cov cua kub tawm, uas yog khaus heev rau cov uas tsis yog - hlau pwm, ua rau pwm puas thiab cov khoom puas.
Cartridge rhaub rau cov uas tsis yog -hlau pwm cua sov feature aultra-tsawg watt ceev(5-10W / cm²), xa maj mam, maj mam cua sov uas hloov tusyees los ntawm pwm yam tsis muaj kev puas tsuaj. Qhov tsawg watt ntom ntom no ua kom cov pwm tuaj yeem ua kom sov thiab sib npaug, tsis txhob muaj cov khoom kub uas ua rau cov yas, cov roj hmab degrade, lossis cov ntoo. Lub tshuab cua sov cov zis yog ntsuas kom haum cov pwm thermal conductivity, tsa cov pwm mus rau qhov zoo tshaj plaws molding kub (80-180℃rau yas, 100-220℃rau roj hmab, 60-100℃rau ntoo) yam tsis muaj kev ruaj ntseg kub txwv.
Kev hloov ntawm cov khoom siv yog lwm qhov tseem ceeb rau cov uas tsis yog- cov cua sov pwm hlau. Lub plhaub sab nrauv yog ua los ntawm du, polished 304 stainless hlau, uas tsis khawb los yog abrade mos uas tsis yog -hlau pwm nto thaum lub sij hawm installation thiab siv. Rau cov yas thiab roj hmab pwm uas tso tshuaj fumes thaum lub sij hawm cua sov, lub sheath resists tshuaj erosion, tswj kom zoo ib yam kub hloov. Cov hlau tsis muaj zog sab hauv yog tsim los rau qis- qhov kub thiab txias, ua haujlwm tas mus li, tsis txhob overheating uas tuaj yeem ua rau pwm puas.
Kev teeb tsa tsim rau cov uas tsis yog- hlau pwm cua sov kuj tau hloov kho los tiv thaiv pwm. Tsis zoo li cov pwm hlau, uas yuav tsum tau ua kom nruj nruj, tsis yog- cov pwm hlau yuav tsum tau xoob, maj mam haum kom tsis txhob tawg lossis tawg thaum lub tshuab rhaub. Cov cua sov rau cov tsis yog-cov pwm hlau yog qhov loj me me nrog qhov sib txawv me me (0.1-0.2mm) kom tsis txhob ua rau pwm puas, thiab lawv feem ntau ua ke nrog cov khoom siv hluav taws xob los txhim kho cov cua sov hla qhov sib txawv, them nyiaj rau cov pwm tsis muaj thermal conductivity.
Cov ntawv thov tseem ceeb rau cov khoom siv tsis yog- hlau pwm lub tshuab cua sov muaj xws li: yas molding rau cov khoom siv me me thiab cov khoom siv yas, cov roj hmab molding rau cov ntsaws ruaj ruaj, gaskets, thiab cov khoom siv roj hmab muag, thiab ntoo molding rau cov khoom siv ntoo thiab cov khoom siv tes ua. Hauv cov ntawv thov no, cov khoom siv tshwj xeeb uas tsis yog- cov cua sov hlau ua kom cov pwm tswj tau qhov kub thiab txias, ua kom zoo tshaj - zoo, tsis zoo- cov khoom dawb yam tsis muaj pwm puas.
Thaum xaiv lub tshuab tso cua sov rau cov khoom tsis yog- cov pwm hlau, cov neeg yuav khoom yuav tsum tau ua ntej peb yam: ultra- tsis tshua muaj watt ntom ntom (tsis pub tshaj 10W / cm²), pwm- cov ntaub ntawv sib xws, thiab kev tswj qhov kub thiab txias. Nws yog ib qho tseem ceeb kom phim lub rhaub qhov kub siab tshaj plaws rau pwm qhov kev tiv thaiv tshav kub - cov pwm yas feem ntau xav tau qhov kub siab tshaj plaws ntawm 180 degree, roj hmab pwm 220 degree, thiab pwm pwm 100℃. Kev siv PID kub tswj nrog lub rhaub yog pom zoo, vim nws tswj qhov kub thiab txias tsis tu ncua nyob rau hauv ± 1 degree, tiv thaiv overheating thiab pwm puas.
Kev saib xyuas cov khoom tsis yog- hlau pwm cua sov yog yooj yim: niaj zaus ntxuav lub hnab kom tshem tawm cov yas, roj hmab, lossis cov khoom seem ntawm ntoo, thiab tsis txhob siv cov tshuaj txhuam hniav uas khawb lub hnab. Tshawb xyuas lub rhaub kom pom cov cim ntawm overheating, xws li discoloration, thiab hloov nws tam sim yog tias xav tau los tiv thaiv pwm.
Tsis yog-cov khoom siv hlau pwm pwm yog cov khoom siv tshwj xeeb tab sis tseem ceeb rau kev tsim khoom me me, kev tsim khoom siv tes ua, thiab kev lag luam molding. Raws li kev thov rau kev cai yas, roj hmab, thiab cov khoom ntoo loj hlob tuaj, qhov kev xav tau ntawm cov tshuab cua sov tshwj xeeb no yuav nce ntxiv. Cov tuam txhab muaj npe nrov muab qhov ntau thiab tsawg thiab cov kev ntsuas fais fab kom haum rau cov khoom tsis zoo uas tsis yog- hlau pwm tsim, muab cov cua sov kho kom haum rau kev lag luam tshwj xeeb no.
Hauv cov ntsiab lus, cov khoom siv hluav taws xob rau cov khoom siv tsis yog- hlau pwm cua sov yog hloov nrog ultra- tsawg watt ceev thiab pwm- cov ntaub ntawv tus phooj ywg kom muaj kev nyab xeeb thiab meej rau cov yas, roj hmab, thiab ntoo pwm. Lawv tiv thaiv pwm kev puas tsuaj thiab ua kom siab - cov khoom tsim tawm zoo, ua rau lawv tsis muaj qhov tseem ceeb rau cov ntawv thov tsis yog - hlau molding. Rau cov neeg yuav khoom hla- ciam teb, cov tshuab cua sov no ua rau lub niche tshwj xeeb thiab ua rau me me - nplai thiab kev tsim khoom lag luam.
