High -Tsuas Kub Resistance Classification of Perforated Heaters & Thermocouple Model Xaiv
Sib txawv siab -kub txhaj tshuaj molding txheej txheem muab tso rau pem hauv ntej sib txawv qhov kub thiab txias kuj yuav tsum tau rau kub khiav cua sov thiab sensing Cheebtsam. Ntau cov kab ntau lawm tau txais kev sib koom ua ke ntawm cov qauv thermocouple rau tag nrho cov perforated heaters, ua rau tsis txaus sensing precision nyob rau hauv ultra- kub kub ua hauj lwm tej yam kev mob thiab kev ua hauj lwm pov tseg nyob rau hauv cov pa kub xwm txheej xwm. Qib sib piv raws li siab - qhov kub thiab txias tsis kam yog qhov tseem ceeb rau kev sib npaug ntawm qhov kev ua tau zoo thiab cov nqi ua haujlwm.
Perforated hot runner heaters tau muab faib ua peb qib siab - kub tiv thaiv qib raws li cov khoom siv thiab cov txheej txheem txheej txheem: hom kub hom, nruab nrab siab - kub hom thiab ultra- hom kub. Cov cua sov perforated yog tsim rau 180-320℃qis thiab nruab nrab kub molding ntawm cov yas zoo xws li ABS thiab PP. Nruab nrab siab -cov khoom kub hloov mus rau 320-380℃txheej txheem ntawm engineering yas xws li PC thiab PBT. Ultra-siab kub perforated heaters stably ua hauj lwm nyob rau hauv 380-420℃ultra-siab kub ib puag ncig rau tshwj xeeb yas xws li PEEK thiab PPS.
Cov qauv thermocouple muaj qhov pom tseeb ntawm qhov ntsuas kub tsis kam ntsuas qhov ciam teb. Ib txwm K- hom thermocouples tsuas yog tsim nyog rau cov xwm txheej kub ib txwm hauv qab 320 degree, nrog kev laus nrawm nrawm thiab muaj teeb meem loj drift hauv siab - qhov kub thiab txias. Standard high -precision thermocouples hloov mus rau nruab nrab siab- kub ua haujlwm ntawm 320-380℃. Txhim kho siab-kub resistant thermocouples tshwj xeeb yog siv rau ultra-high kub xwm txheej siab tshaj 380 degree, tswj kev ruaj khov thermoelectric conversion efficiency thiab paub qhov tseeb.
Raws li qhov siab -cov ntaub ntawv ntsuas qhov kub thiab txias, qhov sib piv ntawm qib tsis sib xws yuav ua rau muaj kev cuam tshuam loj rau kev ua haujlwm. Thaum cov thermocouples zoo sib xws nrog ultra- kub perforated heaters, lub teeb liab drift yuam kev tshaj 5℃tom qab 2000 teev ntawm kev ua hauj lwm, poob tag nrho cov peev xwm tswj qhov kub thiab txias. Kev sib tw qib tuaj yeem tswj tau qhov ntev - lub sijhawm ntsuas qhov yuam kev ntawm lub kaw lus hauv 1.2 degree, tswj cov txheej txheem ruaj khov.
Tsim nyog graded txuam tsis tau tsuas yog xyuas kom meej ntau lawm tab sis kuj optimizes cov cuab yeej nqi peev. Ultra- cov thermocouples qib siab muaj cov nqi yuav khoom ntau dua, thiab kev sib koom ua ke tag nrho yuav ua rau tsis tsim nyog cov nqi pov tseg hauv qis- qhov kub thiab txias qhov xwm txheej. Kev xaiv muab qhab nia tseeb paub meej qhov kev hloov pauv ntawm kev ua haujlwm thiab kev ua haujlwm.
Cov lus hauv qab no qhia tau hais tias qhov siab -kub kuj qib sib piv cov qauv ntawm perforated heaters thiab thermocouple qauv:

Nyob rau hauv qhov project configuration, kub kuj qib sib piv yuav tsum coj lub siab tshaj plaws txheej txheem kub ntawm cov ntaub ntawv ntau lawm raws li tus qauv, tsis txhob parameter deviation los ntawm kub hloov nyob rau hauv lub ntau lawm voj voog. Kev tshuaj xyuas qib tsis tu ncua thiab hloov cov khoom siv kom ntseeg tau tias cov cua sov thiab ntsuas qhov system ib txwm tswj hwm lub xeev hloov pauv.
Kev tshawb fawb graded cov tswv yim sib npaug ntawm cov khoom tsim nyog thiab cov txiaj ntsig kev lag luam, ua kom lub siab - qhov kub thiab txias ua tau zoo ntawm cov cua sov perforated, thiab muab kev ua si tag nrho rau qhov muaj peev xwm ua tau zoo ntawm cov thermocouples. Kev xaiv qib kev tshaj lij thiab kev teeb tsa kev teeb tsa tsim lub hom phiaj ntsuas kub tswj kev daws teeb meem rau qhov sib txawv precision txhaj molding scenarios.
