Pwm hluav taws xob cua sov raj feem ntau yog siv los ua kom sov pwm. Feem ntau siv pwm hluav taws xob cua sov raj muaj xws li pwm ib lub taub hau hluav taws xob cua sov raj thiab ob lub taub hau hluav taws xob cua sov raj. Cov pwm hluav taws xob cua sov raj tuaj yeem ntsuas cov thermocouples thiab cov baffles ruaj khov hauv qhov chaw ruaj khov. Yog li yuav ua li cas xaiv cov pwm hluav taws xob cua sov raj? Feem ntau los ntawm cov yeeb nkab txoj kab uas hla, qhov ntev, yeeb nkab thiab lwm yam kev xaiv.
1. Cov pwm hluav taws xob cua sov raj yuav tsum tau txiav txim siab raws li qhov loj ntawm pwm aperture, yog tias pwm aperture yog 10 hli, cov yeeb nkab txoj kab uas hla ntawm pwm hluav taws xob cua sov raj tuaj yeem yog 9.8 hli.
2. Qhov ntev ntawm cov pwm hluav taws xob cua sov raj muaj qhov ntev ntawm cov hluav taws xob cua sov raj.
3. Kev xaiv cov khoom siv ntawm cov pwm hluav taws xob cua sov raj yuav tsum tau txiav txim siab raws li kev ua haujlwm kub ntawm pwm. Vim lub sij hawm conduction sib txawv ntawm pwm kub thiab qhov kub thiab txias ntawm pwm hluav taws xob cua sov raj.
(1) Thaum pwm kub yog 150 degrees, qhov kub ntawm lub pwm hluav taws xob cua sov raj yuav yog li 300 degrees. Lub sijhawm no, cov khoom siv ntawm cov pwm hluav taws xob cua sov yeeb nkab yuav tsum yog 300 degrees stainless hlau 304.
(2) Thaum pwm kub yog 200 degrees, qhov kub ntawm lub pwm hluav taws xob cua sov raj yuav yog li 400 degrees. Lub sijhawm no, cov khoom siv yeeb nkab ntawm pwm hluav taws xob cua sov raj yuav tsum yog 500 degrees stainless hlau 321.
(3) Thaum pwm kub yog 450 degrees, qhov kub ntawm lub pwm hluav taws xob cua sov raj yuav yog 600 degrees. Lub sijhawm no, cov khoom siv stainless hlau 310S yuav tsum raug xaiv, thiab nws qhov kub tsis kam yog 700 degrees.
Ntawm chav kawm, qhov sib txawv ntawm qhov kub ntawm cov cua sov yuav tsum sib txawv raws li tus naj npawb ntawm cov hauv paus hniav thiab pwm loj ntawm cov ntsia hlau cua sov. Qhov no yuav tsum muaj qhov ntev los txiav txim.
