Dab tsi yog qhov tshwm sim ntawm CMRR tsis txaus?

Kev ruaj ntseg ntawm kev txhaj tshuaj molding thiab cov khoom lag luam zoo yog cuam tshuam los ntawm qhov tsis txaus CMRR, uas ua rau muaj kev tswj xyuas qhov kub thiab txias hauv qhov kub khiav, kub hloov pauv, cov khoom tsis zoo, thiab txawm tias cov khoom tawg.

 

1. Direct Repercussions: Kev tswj kub tsis txaus ntseeg

Temperature Display Jumps lossis Drifts: Thaum cov suab nrov pwm ua yuam kev rau lub teeb liab kub, kev nyeem ntawv ntsuas kub tuaj yeem hloov pauv ntau (los ntawm ± 10℃lossis ntau dua);

PID Control Malfunction: Kev tswj xyuas tsis tu ncua ua rau cov cua sov tso tawm kom hloov pauv, uas yuav ua rau cov khoom txias lossis kub dhau;

Ntau-Cavity Imbalance: sib txawv raws nyob rau hauv ntau-nozzle systems ntsib ntau theem ntawm kev cuam tshuam, uas tuaj yeem ua rau kev txhaj tshuaj luv luv, flash, lossis tsis sib xws.

Cov ntaub ntawv siv tau: Tsis txaus CMRR (tsuas yog 50dB) ua rau kub khiav kub ntawm ± 15℃hauv cov khoom siv yas kho mob, ua rau tawm - ntawm - qhov ntev ntawm cov khoom lag luam thiab batch scrapping.

 

2. Teeb meem nrog cov khoom zoo

Hom Defect

Vim

Kev txhaj tshuaj luv luv

Kev tswj qhov kub thiab txias misjudges "overheating," instantly cools down thaum qhov tiag kub yog tsawg heev vim lub suab nrov.

Flash (Burs)

misinterpreted li "tsawg kub," uas ua rau cov cua kub tsis tu ncua, spillage, thiab carbonization ntawm cov khoom.

Kev nce hauv kev ntxhov siab

Kev tsis sib xws ntawm cov dej ntws los ntawm qhov kub thiab txias ua rau muaj qhov tsis sib xws ntawm qhov nro tom qab txias.

Qhov chaw flaws lossis xim txawv

Khoom deterioration coj los ntawm localized overheating txo qhov zoo ntawm cov tsos.

Ceeb Toom: Cov kev tsis txaus siab tam sim no ua rau cov neeg siv khoom rov qab los, cov kab ntau lawm raug kaw, thiab kev thov hauv siab - yuav tsum muaj kev lag luam suav nrog tsheb thiab kev kho mob.

 

3. Qhov cuam tshuam rau kev tsim khoom thiab cov khoom siv

Txo Cov Hluav Taws Xob Hluav Taws Xob Lifespan: Cov cua sov lub caij nyoog laus zuj zus los ntawm kev pib nquag- nce thiab kub dhau.

System Alarm Shutdown: Unplanned shutdowns yog tshwm sim los ntawm kev tiv thaiv kab mob tshwm sim los ntawm irregularities nyob rau hauv qhov kub thiab txias.

Cov Nqi Them Nyiaj Ntau Ntxiv: Yuav tsum muaj kev daws teeb meem tsis tu ncua ntawm "xav tias qhov teeb meem tsis ua haujlwm," uas ua rau tus nqi ntawm kev ua haujlwm thiab cov khoom hloov pauv.

Kev nkag siab zoo: "CMRR tsis txaus ≠ Cov khoom siv tsis ua haujlwm," txawm li cas los xij, nws cov txiaj ntsig zoo sib piv rau lub cev tsis sib haum xeeb uas nyuaj rau kev tshem tawm.

 

4. Yuav ua li cas thiaj li zam tau qhov kev phom sij los ntawm CMRR tsis txaus?

Kev tswj kev xaiv: Thaum ua kev yuav khoom, xyuas kom meej tias qhov ntsuas kub tswj tau muaj CMRR yam tsawg 80 dB;

Cov txheej txheem xaim: Khaws nws kom deb ntawm cov kab hluav taws xob thiab siv cov ntaub thaiv kev sib tw -pair xaim nrog ib qho - taw tes hauv av;

Kev rho tawm hluav taws xob: teeb tsa DC-DC module lossis rho tawm hloov pauv rau qhov ntsuas kub;

Kev tshuaj xyuas tsis tu ncua: Tshawb xyuas cov teeb liab lub suab nrov uas siv lub oscilloscope thiab kho cov teeb meem sai sai.

Lub hauv paus ntsiab lus ntawm kev nyab xeeb: Kev tiv thaiv triple ntawm "High CMRR + shielding + kev cais tawm" yog qhov tseem ceeb los lav qhov kev ua haujlwm kub kub.
