Residual Thaum tshav kub kub Release Stability ntawm Indirect Lead Heating Tubes rau ceev ceev cua txias Industrial txheej txheem
Ntau cov txheej txheem kev lag luam yuav tsum tau ua kom cua sov sai thiab ceev cua txias hloov mus, xws li pwm tsim sai, luv luv - cov khoom siv kho kom zoo thiab cov txheej txheem kev kho cua sov tsis tu ncua. Residual heat disorder ntawm cov cua sov raj yog qhov tseem ceeb ua rau cov txheej txheem tsis ruaj khov hauv cov xwm txheej zoo li no. Cov khoom siv hluav taws xob ncaj qha hluav taws xob cua sov cov raj muaj lub tshuab hluav taws xob loj hauv lub tshav kub, uas ua rau qeeb qhov hluav taws kub tso tawm thiab kub kub dhau tom qab fais fab tuag. Indirect lead cua sov tubs txais yuav tsawg thermal loj hloov pas nrig qauv kom paub ceev ceev residual tshav kub dissipation thiab ceev kub pib dua, sib piv ceev ceev cov txheej txheem yuav tsum tau thiab tswj kom meej lub voj voog kub tswj nrog thermocouple dynamic xyuas.
Cov txheej txheem cua txias nrawm tso rau pem hauv ntej cov kev cai nruj ntawm thermal teb ceev ntawm cov khoom cua sov. Tom qab ua tiav cov txheej txheem cua sov, cov cuab yeej yuav tsum tau txias mus rau qhov teeb tsa qis - qhov kub thiab txias hauv lub sijhawm luv luv kom nkag mus rau lub voj voog ntau lawm tom ntej. Cov hluav taws xob hluav taws xob hluav taws xob ncaj qha ua ke nrog cov txheej txheej tuab tuab thiab ntau - txheej txheej sib xyaw ntawm cov hlau qhov hluav taws xob, uas khaws cov khoom siv hluav taws xob ntau thaum cua sov. Tom qab hluav taws xob txiav tawm, cov hluav taws kub uas seem tshuav txuas ntxiv mus rau sab nraud rau lub sijhawm ntev, ua rau cov cuab yeej txias txias thiab ncua sij hawm ntau lawm.
Uncontrolled residual heat ua rau cov txheej txheem loj kub overshoot. Qhov ntsuas kub tiag tiag tom qab lub hwj chim tawm yog siab dua li txheej txheem txheej txheem txias txias, uas ua rau dhau - kho, overheating deformation thiab cov khoom ua tau zoo sib txawv ntawm cov khoom precision. Nyob rau hauv batch cyclic ntau lawm, residual tshav kub tsub kom sib txawv nyob rau hauv txhua lub voj voog ua rau inconsistent khoom zoo. Nyob rau tib lub sijhawm, qhov tsis sib xws ntawm cov cua sov tso tawm cuam tshuam nrog kev txiav txim siab ntawm qhov ntsuas kub ntawm thermocouple, ua rau nws tsis yooj yim rau lub kaw lus kom txiav txim siab lub sijhawm ua tiav qhov txias txias, ua rau muaj kev cuam tshuam ntau lawm.
Indirect lead cua sov tubes txo cov davhlau ya nyob twg thermal mass fundamentally los ntawm streamlined hlau hloov pas nrig tsim. Cov khoom siv hlau pas nrig muaj cov khoom siv hluav taws xob tsawg thiab cov khoom siv hluav taws xob ceev ceev, tsis muaj cov khoom siv hluav taws xob ntau ntawm cov khoom siv hluav taws xob. Tom qab lub hwj chim txiav tawm, cov hluav taws kub uas nyob hauv lub raj lub cev thiab lub davhlau ya nyob twg dissipates sai thiab sib npaug, paub txog qhov kub thiab txias rov pib dua yam tsis muaj hluav taws xob qeeb. Tag nrho cov thermal teb ceev tau zoo dua piv nrog cov hluav taws xob hluav taws xob hluav taws xob ncaj qha.
Cov txheej txheem segmented kev cais tawm kom tsis txhob muaj kev cuam tshuam los ntawm cov hluav taws xob seem - cuam tshuam. Cov hlau hloov pas nrig cais lub siab kub cia tub raj lub cev los ntawm cov kab hluav taws xob sab nraud, kom ntseeg tau tias cov cua sov seem tsuas yog nyob rau hauv cov cua kub tseem ceeb thiab dissipates sai raws lub raj phab ntsa. Tsis muaj qhov chaw seem uas nyob hauv lub tshav kub tuag yog tsim ntawm lub qhov ncauj raj, tshem tawm tag nrho ntev - lub sij hawm davhlau ya nyob twg tshav kub tawg tom qab fais fab tuag. Txoj cai tsis sib xws thaum tshav kub kub dissipation ua rau txhua qhov cua sov thiab cua txias kom zoo ib yam.
Fast residual tso cua sov optimizes thermocouple kaw - voj voj voog tswj qhov tseeb. Qhov ntsuas kub hloov pauv ntawm cov hlau lead cua kub tsis ncaj yog linear thiab thim rov qab, ua rau lub tshuab thermocouple kom raug ntes tus nqi cua txias thiab cov kev cai ntawm cov cua sov seem. Lub kaw lus tswj qhov kub thiab txias tuaj yeem tsim lub zog muaj tseeb-tawm ncua sijhawm thiab lub sijhawm txias txias raws li cov ntaub ntawv ntsuas kub ntawm lub sijhawm tiag tiag, daws qhov teeb meem ntawm cov txheej txheem kub overshoot tshwm sim los ntawm cov hluav taws kub poob.
Rau luv luv - voj voog ceev cua sov thiab cua txias ntau lawm kab, precision pwm cyclic ua thiab cov khoom siv thermal kho tsis sib haum, cov hlau lead cua kub tsis ncaj los daws qhov seem ntawm cov cua sov hysteresis qhov mob ntawm cov khoom cua sov. Kev koom tes nrog siab - teb cov thermocouple dynamic xyuas, lawv paub siab -precision thiab siab-kev ua tau zoo cyclic industrial kub tswj.
