Rise Rise Rate Matching Principple of Single -Xaiv cua sov Rods rau cov txheej txheem pwm sib txawv
Qhov ntsuas kub nce siab yog ib qho ntawm cov txheej txheem tseem ceeb ntawm ib qho - kawg daim ntawv thov cua sov pas nrig. Cov txheej txheem pwm sib txawv muaj cov kev cai sib txawv ntawm cov cua kub ceev: qee cov txheej txheem yuav tsum tau kub ceev kom txhim kho lub voj voog efficiency, thaum precision molding txheej txheem yuav tsum ruaj khov thiab qeeb kub nce kom tsis txhob muaj thermal stress ntawm pwm. Qhov muag tsis pom kev nrhiav cua kub ceev los yog siv cov txheej txheem ntsuas kub ruaj khov yuav ua rau cov khoom siv qis qis lossis cov khoom tsis ruaj khov. Mastering lub hauv paus ntsiab lus ntawm qhov kub thiab txias nce tus nqi thiab pwm txheej txheem yog tus yuam sij rau optimize ntau lawm efficiency thiab txheej txheem stability.
Qhov kub nce tus nqi ntawm ib qho -kawg cua sov pas nrig yog txiav txim los ntawm peb yam tseem ceeb: lub zog ceev ntawm lub cev pas nrig, pwm kub dissipation tej yam kev mob thiab haum qhov sib txawv nruj. High power density corresponds to fast temperature rise speed, while low power density is stable and slow in heating. Qhov nruj ntawm qhov sib txawv ntawm qhov sib txawv ncaj qha cuam tshuam rau cov thermal conduction efficiency. Ib qho kev sib txawv ua kom muaj kev sib txawv ntawm qhov kub thiab txias, thaum qhov sib txawv ntau dhau ua rau qhov kub thiab txias qeeb thiab cov lus teb qeeb. Cov pwm sib txawv xws li pwm tuab, nyias pwm, qhov sib sib zog nqus kab noj hniav thiab cov kab noj hniav ntiav kuj muaj qhov sib txawv ntawm cov cua sov thiab cov cua kub dissipation ceev, uas ua rau qhov sib txawv ntawm qhov kub thiab txias los ntawm cov cua sov rods nrog tib lub zog.
Kev kub ceev nrawm sib txuam yog tsim rau kev sib tshuam batch ua pwm. Thermal txiav pwm, kub nias molding pwm thiab me me batch ceev hloov pwm muaj luv ib zaug - lub sij hawm voj voog thiab nquag pib - nres. Cov txheej txheem zoo li no yuav tsum tau lub pas nrig cua sov kom ncav cuag qhov txheej txheem kub sai sai tom qab pib ua kom luv lub sijhawm tos thiab txhim kho kev sib tw ntau lawm. Los ntawm kev teeb tsa nruab nrab thiab siab zog ceev ib zaug -kawg cua sov rods thiab optimizing lub installation qhov sib txawv los xyuas kom meej cov cua sov conduction, cov pwm tuaj yeem ua kom tiav qhov kub thiab txias tsis pub dhau 3-5 feeb, uas txhim kho cov txiaj ntsig zoo ntawm batch ntau lawm.
Kev ruaj ntseg qeeb kub nce hom yog haum rau siab -precision nyias- phab ntsa txhaj pwm. Ultra- cov khoom yas nyias thiab cov khoom ua kom zoo yog qhov nkag siab zoo rau pwm thermal stress. Kev kub ceev ceev tag nrho yuav ua rau tsis sib xws thermal expansion ntawm cov pwm, ua rau cov pwm me me deformation, cov khoom warpage thiab loj sib txawv. Tsawg zog cua sov rods thiab graded kub nce cov txheej txheem yog saws los ua kom sov lub pwm maj mam thiab uniformly, tshem tawm sab hauv thermal kev nyuaj siab ntawm pwm, xyuas kom meej synchronous thiab sib npaug kub nce ntawm tag nrho cov qhov chaw ntawm kab noj hniav, thiab maximize lub molding raug ntawm precision khoom.
Qhov kub thiab txias tsis tu ncua thiab kev txuag hluav taws xob yog siv tau rau cov kab ntau lawm tsis siv neeg xws li ntim cov cua sov sealing. Cov cuab yeej ntim khoom khiav tsis cuam tshuam rau lub sijhawm ntev, thiab cov txheej txheem yuav tsum muaj qhov kub thiab txias tsis tu ncua es tsis yog ultra- kub nce ceev. Kev kub ceev heev yuav ua rau kub kub overshoot, nquag hloov lub hwj chim ntawm tus tswj kub, thiab tsis ruaj tsis khov thaum tshav kub sealing nyhuv. Cov hluav taws xob tsis tshua muaj hluav taws xob qis qis yog txuam nrog PID cov txheej txheem tswj qhov kub thiab txias kom paub qhov kub thiab txias kom ruaj khov, kom ntseeg tau tias cov khoom ntim khoom zoo sib xws rau lub sijhawm ntev.
Qhov ntsuas kub tsis tsim nyog nce tus nqi sib piv yuav ua rau pom tseeb cov txheej txheem tsis xws luag. Kev kub ceev heev ntawm precision pwm ua rau thermal deformation thiab cov khoom deformation; qeeb cua sov ntawm batch pwm ua rau lub sij hawm ntev lub voj voog thiab txo cov zis; nquag kub overshoot ua rau cov txheej txheem tsis ruaj khov thiab nce tus nqi tsis zoo. Tsuas yog los ntawm kev sib piv qhov kub nce cov yam ntxwv ntawm cov cua sov rods raws li cov txheej txheem cov cwj pwm tuaj yeem sib npaug ntawm kev ua haujlwm zoo thiab zoo.
Ntawm - site parameter debugging yuav tsum tau muab cov qauv pwm thiab ua haujlwm sib dhos. Cov pwm tuab yuav tsum tsim nyog ua kom muaj zog ceev kom them nyiaj rau cov khoom siv cua sov; nyias pwm xav tau qis- lub zog qeeb cua sov kom tsis txhob muaj cua sov; ntom ntau- qhov pwm yuav tsum muaj lub zog sib npaug los xyuas kom meej qhov kub thiab txias ntawm txhua txoj haujlwm. Kev tshawb fawb kub nce tus nqi sib piv yog ib feem tseem ceeb ntawm cov txheej txheem pwm ua kom zoo dua qub, uas tuaj yeem txhim kho kev ua tau zoo thiab cov khoom tsim nyog tus nqi.
