Niaj hnub nimno kub khiav tshuab, tshwj xeeb tshaj yog cov uas siv nyob rau hauv loj los yog ntau- kab noj hniav pwm, cia siab rau multi- cheeb tsam kub tswj kom ua tau zoo ib yam ntawm cov yaj ntws thiab ib feem zoo. Txhua cheeb tsam -feem ntau suav nrog cov manifold thiab txhua tus nozzle- ua haujlwm ua ib qho hluav taws xob cua sov. Nyob rau hauv nruab nrab ntawm txhua cheeb tsam yog ib lub thermocouple, uas muab cov ntaub ntawv tiag tiag -lub sij hawm kub xav tau rau kev tswj kom meej. Yog tsis muaj siab -kev ua tau zoo thermocouples, ntau-zone systems tsis tuaj yeem ua haujlwm tau zoo, ua rau muaj kev tsis sib xws, tsis zoo, thiab kev tsim khoom tsis zoo.
Ntau - cheeb tsam tswj yog tsim nyog vim hais tias txawv seem ntawm cov kub khiav muaj qhov sib txawv ntawm cov cua sov. Lub manifold, uas faib cov yaj mus rau ntau lub nozzles, ua haujlwm ntawm qhov sib txawv me ntsis dua li cov lus qhia nozzle. Nyob rau hauv cov pwm complex, cov nozzles sab nrauv yuav poob cua sov sai dua li qhov nruab nrab, yuav tsum tau hloov kho ywj siab. Txhua cheeb tsam yuav tsum tau tswj nyias kom tswj tau cov viscosity zoo ib yam thiab siab thoob plaws txhua qhov kab noj hniav. Thermocouples ua rau theem ntawm kev tswj tau los ntawm kev muab kev txuas ntxiv, thaj tsam - cov lus qhia tshwj xeeb.
Uniformity yog lub hom phiaj tseem ceeb ntawm ntau -zone systems. Txawm tias qhov sib txawv me me ntawm cov nozzles tuaj yeem ua rau tsis muaj qhov sib npaug, ua rau overpacking hauv qee qhov kab noj hniav thiab txhaj tshuaj luv luv rau lwm tus. Thermocouples pom qhov txawv me me li 1℃mus rau 2 degree, tso cai rau tus maub los kho lub zog hluav taws xob dynamically. Qib no ntawm kev ua kom ntseeg tau tias txhua qhov kab noj hniav tau txais cov cua sov zoo ib yam, uas yog qhov tseem ceeb rau kev tsim khoom siab -.
Thermocouples kuj tseem ua kom muaj kev ua txhaum kev ywj pheej. Hauv ntau- cheeb tsam system, tsis ua hauj lwm lossis drift hauv ib lub sensor yuav tsum tsis txhob cuam tshuam tag nrho cov haujlwm. Advanced controllers saib xyuas txhua lub thermocouple ib tus zuj zus, kuaj pom cov kab hluav taws xob qhib, luv Circuit Court, thiab qhov kub tsis zoo. Yog tias ib cheeb tsam ua tsis tiav, lub kaw lus tuaj yeem ceeb toom cov neeg ua haujlwm lossis kaw tsuas yog thaj tsam cuam tshuam, txo qis qis qis thiab seem.
Teb ceev yog qhov tseem ceeb tshwj xeeb tshaj yog nyob rau hauv ntau- thaj chaw teeb tsa. Thaum pib thiab tsim khoom, kev hloov pauv kub tshwm sim ib txhij hla ntau thaj chaw. Fast- teb cov thermocouples tso cai rau tus maub los synchronize cua sov hloov kho, tiv thaiv overshoot thiab xyuas kom txhua cheeb tsam mus txog qhov teeb meem tib lub sijhawm. Cov sensors qeeb lossis tsis ruaj khov tsim cov nyhuv cascading ntawm thermal imbalance uas nyuaj rau kho.
Hluav taws xob teeb liab kev ncaj ncees yog qhov tseem ceeb nyob rau hauv ntom ntau-zone configurations. Nrog kaum ob ntawm cov thermocouples thiab cov cua sov ua haujlwm nyob ze, kev cuam tshuam ntawm electromagnetic yog muaj. Siab- zoo tiv thaiv thermocouples tswj kom huv si, tiv thaiv tus ntoo khaub lig- tham ntawm ib cheeb tsam. Qhov no ua kom txhua qhov cua sov ua haujlwm ntawm nws tus kheej yam tsis muaj kev cuam tshuam.
Ntev -lub sij hawm ruaj khov yog qhov tseem ceeb rau kev tsim khoom tas mus li. Ntau - cheeb tsam kub khiav feem ntau khiav rau lub lis piam lossis hli yam tsis muaj kev cuam tshuam. Thermocouples yuav tsum tiv thaiv drift, oxidation, thiab thermal qaug zog kom tswj tau qhov sib xws. Tsawg-cov sensors zoo ua rau thaj tsam tsis sib npaug, ua rau muaj kev cuam tshuam ntau ntxiv nyob rau lub sijhawm yam tsis muaj kev ceeb toom pom tseeb.
Flexibility thiab adaptability yog cov txiaj ntsig ntxiv. Multi-zone systems tso cai rau cov txheej txheem kho qhov kub thiab txias rau cov resins sib txawv, ib feem geometry, thiab lub voj voog ceev. Thermocouples muab cov lus qhia tseeb uas yuav tsum tau ua kom zoo - kho txhua cheeb tsam kom tau txais txiaj ntsig zoo. Qhov kev hloov pauv no ua rau ntau - cheeb tsam kub khiav tsim nyog rau ntau yam kev siv.
Hauv cov ntsiab lus, cov thermocouples yog lub hauv paus ntawm ntau -zone kub khiav tshuab. Lawv ua kom muaj kev tswj hwm ywj pheej, cov cua sov tsis sib xws, kuaj pom qhov tsis raug, thiab kev ruaj ntseg ntau lawm. Raws li pwm ua ntau dua thiab cavitation nce, qhov tseem ceeb ntawm siab -kev ua tau zoo thermocouples tsuas yog txuas ntxiv mus.
