Nozzle Fitting Gap Thermal Resistance: Thermocouple Contact Compensation Technology rau Cov Cuab Yeej Me Me
Nozzle heaters belongs rau cov khoom siv hluav taws xob me me, thiab cov khoom sib dhos me me yuav ua rau pom tseeb qhov ntsuas kub sib txawv. Ntau qhov kev txhaj tshuaj molding kab muaj qhov siab - cov cua sov nozzle zoo thiab cov thermocouple sensors raug, tab sis tsis tuaj yeem tshem tawm qhov kub thiab txias tsis sib xws, uas feem ntau tshwm sim los ntawm kev tiv thaiv kev tiv thaiv thermal tsis raug. Raws li cov txheej txheem cua sov me me debugging kev paub dhau los, lub qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob.
Cov qauv nozzle me me nrog lub zog cua kub siab ceev, thiab cov cua sov hloov pauv tsuas yog nyob rau hauv kev sib cuag zoo ntawm cov cua sov sab hauv phab ntsa thiab cov phab ntsa sab nrauv. Kev sib dhos me me yuav ua rau huab cua thermal tiv thaiv txheej uas tsis tshua muaj hluav taws xob hloov hluav taws xob, ua rau cov cua sov hauv zos hauv lub rhaub thiab tsis txaus hloov hluav taws xob ntawm lub nozzle nto. Qhov sib txawv ntawm qhov loj - qhov loj qhov cub rhaub nrog cov cua sov dissipation tsis muaj peev xwm, cov tshuab hluav taws xob me me nozzle tsis muaj qhov ua yuam kev, thiab micron - theem sib txawv yuav ua kom pom tseeb qhov sib txawv ntawm qhov kub thiab txias.
Txawv nozzle rhaub cov qauv muaj qhov sib txawv rhiab heev. Qhib mica cov qauv muaj qee yam deformation adaptability, uas tuaj yeem haum cov nozzles los ntawm extrusion deformation, nrog qhov sib txawv tsis tshua muaj siab tab sis tsis zoo ntev - lub sij hawm deformation stability. Segmented ceramic cov qauv muaj lub cev nruj thiab qhov sib txawv siab, thiab qhov sib txawv me me yuav ua rau muaj qhov sib txawv ntawm cov cua sov dissipation thiab cov chaw txias hauv zos. Integral cam khwb cia tooj liab qauv muaj siab zuag qhia tag nrho rigidity, nrog heev nruj kev cai ntawm haum haum, thiab tsis tsim nyog qhov khoob yuav ua kom pom tseeb thermocouple sampling deviation.
Kev tiv thaiv thermal tsis tuaj yeem raug tshem tawm los ntawm cov pa static calibration. Gap thermal kuj hloov dynamically nrog thermal expansion thiab contraction thaum lub sij hawm ua hauj lwm cov cuab yeej, ua tiag tiag - lub sij hawm sib txawv ntawm qhov sib txawv. Tsau thermocouple calibration tsis tuaj yeem hloov mus rau qhov hloov pauv hloov pauv, ua rau lub sijhawm ntev - qhov ntsuas kub yuam kev. Cov kws tshaj lij qib kev sib cuag them nyiaj thev naus laus zis tsim cov qauv kev ua yuam kev tsis zoo raws li qhov sib txawv loj thiab cov yam ntxwv ntawm cov qauv, ua kom paub tseeb- lub sij hawm kho ntawm thermal resistance deviation.
Fitting test cov ntaub ntawv txheeb xyuas qhov raug them nyiaj. Rau 0.03mm me me haum qhov khoob uas muaj nyob rau hauv nozzle installation, uncompensated thermocouple sib txawv mus txog 0.9℃rau ceramic lug, 0.6℃rau mica lug, thiab 1.1℃rau cam khwb cia tooj liab lug. Tom qab lub hom phiaj kev sib cuag them nyiaj calibration, sib txawv ntawm tag nrho cov qauv yog tswj nyob rau hauv 0.3 degree, tshem tawm tag nrho qhov sib txawv -induced kub instability.
Tej yam me me nozzle cua sov tshuab xav tau ntau dua precision installation txuam thiab yuam kev calibration. Kev paub txog kev sib haum xeeb thiab kev hloov kho thermocouple tiv tauj cov phiaj xwm tuaj yeem ua kom cov cua sov ua haujlwm ntawm lub tshuab cua sov thiab xyuas kom meej ultra- qhov kub thiab txias tswj ntawm kev txhaj tshuaj molding nozzle xaus.
