Yuav ua li cas nce lub zog nqus ntawm cov hlau nplaum?
Rau daim ntawv thov ntawm kev sib nqus attraction, txhua tus neeg them nyiaj zoo rau lub zog attraction ntawm cov hlau nplaum. Lub zog nqus ntawm cov hlau nplaum tuaj yeem suav tau (rub lub tshuab xam zauv), thiab cov qauv hauv qab no tuaj yeem siv rau kev siv, tab sis nws yuav tsum tau muab sau tseg tias cov txheej txheem ua ntej ntawm cov mis yog qhov zoo tagnrho, uas yog, cov khoom sib nqus sib nqus yog heev. uniform, thiab sib nqus permeability ntawm cov khoom nyiam yog siab heev (cov ntaub ntawv tsis muaj zog sib nqus xws li 300 series stainless hlau thiab lwm yam ferroalloys tsis siv tau), lub thickness thiab adsorption cheeb tsam yog txaus (lub zog nqus yuav tsis zoo dua yog tias cov thickness. thiab cheeb tsam tau nce, uas yog, sib nqus flux to tsis suav nrog), txawm li ntawd los, tus nqi suav tsuas yog siv tau raws li kev siv, tsis yog rau kev suav xam.
F(N)=2*S(m²)*B(T)²/μ0
Ntawm lawv, S sawv cev rau thaj chaw adsorption, B sawv cev rau huab cua sib nqus sib nqus flux ntom ntom, thiab μ0 yog lub tshuab nqus tsev permeability (ib qhov tsis tu ncua, μ0=4π * 10-7).
Los ntawm cov qauv, peb tuaj yeem pom tias lub zog nqus ntawm cov hlau nplaum yog proportional rau thaj chaw adsorption thiab cov huab cua sib nqus sib nqus flux ceev. Nws tuaj yeem pom tau tias ua rau thaj tsam adsorption thiab ua kom cov pa sib nqus sib nqus flux ceev yog ob txoj hauv kev los ua kom lub zog nqus ntawm cov hlau nplaum.
1. Ua kom thaj tsam adsorption
Cov khoom nyiam yuav tsum tsawg kawg tuaj yeem npog cov hlau nplaum adsorption nto, thiab qhov tuab ntawm cov khoom nyiam tuaj yeem nce ntxiv yog tias muaj kev tso cai.
Thaum ib tug hlau nplaum attracts hlau phaj:
Qhov loj dua qhov adsorption cheeb tsam ntawm cov hlau phaj thiab cov hlau nplaum, lub zog nqus ntawm cov hlau nplaum thiab cov hlau phaj ntau dua. Thaum qhov chaw adsorption sib npaug rau thaj tsam ntawm cov hlau nplaum, qhov kev nyiam ntawm lub zog nqus kom loj dua yuav maj mam qeeb. Thaum lub phaj hlau loj txaus, nce lub zog nqus. Qhov chaw ntawm lub phaj hlau yuav tsis txhim kho qhov nqus;
Thaum thaj tsam ntawm cov phaj hlau yog tib yam, thaum lub thickness ntawm cov phaj hlau yog nyias, ua kom cov thickness ntawm cov phaj hlau tuaj yeem ua rau kom lub zog nqus; thaum lub phaj hlau yog thicker, ua rau lub thickness ntawm cov hlau phaj yuav maj mam nce lub zog nqus kom txog thaum tsis muaj qhov nce.
2. Ua kom cov huab cua sib txawv flux ceev
Thaum lub adsorption cheeb tsam S nyob tas li, nrhiav txoj hauv kev los ua kom cov huab cua sib txawv ntawm qhov sib txawv thiab txo qhov sib nqus flux leakage yuav yog ib txoj hauv kev zoo dua los ua kom lub zog nqus, thiab cov hlau nplaum flux tuaj yeem txo tau los ntawm ntau tus ncej magnetization.
Los ntawm daim duab magnetic teb simulation, peb tuaj yeem pom tias tom qab cov hlau nplaum hloov pauv mus rau bipolar magnetization, cov hlau nplaum sib nqus tau txo qis, thiab ib feem ntawm cov kab hlau nplaum sib nqus ua rau lub voj voog sib nqus kaw hauv cov ntawv hlau adsorbed.
Yog hais tias tus naj npawb ntawm cov ncej yog ntxiv, thiab ib daim ntawv hlau nplaum txuas ntxiv rau hauv qab ntawm cov hlau nplaum, qhov sib nqus flux leakage yuav raug txo kom tsawg, thiab lub zog nqus yuav raug txhim kho ntxiv.
Cov qauv tsim tam sim no ntawm cov khoom sib nqus yog txhawm rau txhawm rau siv cov khoom sib nqus kom ntau li ntau tau. Los ntawm kev tsim ntawm ntau tus ncej sib nqus Circuit Court lossis Halbeck sib nqus Circuit Court, lossis los ntawm kev taw qhia ntawm qee cov ntaub ntawv nrog siab sib nqus permeability, cov hlau nplaum tuaj yeem hla ntau li ntau tau. Cov khoom nqus tau tsim ib lub voj voog sib nqus kaw. Tej kev siv yog:
Cov roj hmab sib nqus daim ntawv yog tsim los rau ntau theem magnetization, ib txhia yog ob-sided multi-ncej, thiab ib txhia yog ib leeg-sided multi-ncej. Cov hlau nplaum kev ua haujlwm ntawm cov hlau nplaum roj hmab yog qhov tsawg heev, tab sis tom qab ntau tus ncej sib nqus hluav taws xob tsim, cov hlau nplaum sib nqus yog densely faib rau ntawm qhov chaw. Sib nqus flux to tsawg heev thaum lub sij hawm adsorption, ua rau cov nyhuv adsorption zoo dua;
Cov cuab yeej sib nqus ntawm lub qhov rooj nqus, los ntawm kev taw qhia ntawm daim ntawv qhia sib nqus, ua rau cov hlau nplaum yuav luag tsim ib lub voj voog los ntawm cov khoom siv adsorption thaum lub sij hawm adsorption, yog li ntawd qhov kev siv ntawm cov hlau nplaum yog siab heev, thiab qhov kev paub zoo yog ib tug me me sib nqus attraction, lub suction quab yuam yog loj thaum nyob rau hauv kev sib cuag ncaj qha.
Tus tsim ntawm qhov sib nqus attraction yog inseparable los ntawm kev txiav txim siab ntawm qhov adsorption nrug. Cov lus hais saum toj no adsorption yog raws li kev sib cuag ncaj qha. Yog tias qhov kev ncua deb hloov, lub zog nqus feem ntau hloov pauv ntau. Cov duab hauv qab no qhia tau hais tias muaj ntau yam hlau nplaum ib leeg. Cov khoom siv thiab cov khoom sib nqus sib nqus muaj ntau txoj cai zoo sib xws. Qhov ntau tus ncej, lub zog nqus ntau dua thaum qhov sib nrug yog 0, tab sis lub zog nqus yuav tsis muaj zog thaum qhov sib txawv nce.
