Lub hauv paus ntsiab lus thiab daim ntawv thov ntawm electrostatic tester
Hauv qee qhov chaw electrostatic rhiab, xws li kev tsim cov khoom siv hluav taws xob, thaj chaw sib dhos, chav nyob ntsiag to, chav khoos phis tawj, chaw muag tshuaj thiab RD kuaj, chav ua haujlwm, khoom siv kho mob, tshuab luam ntawv, ntim khoom lag luam, thiab lwm yam, ntsuas cov khoom siv hluav taws xob yog qhov xav tau, yog li Kev siv cov tshuab ntsuas ntsuas hluav taws xob tau hloov zuj zus thiab ntau dua.
Cov hluav taws xob zoo li qub, hais lus nruj me ntsis, hais txog qhov tseeb tias lub txim tsis txav, tab sis nyob rau hauv ib txwm muaj xwm txheej, daim ntawv thov ntawm hluav taws xob zoo li qub kuj suav nrog kev siv hluav taws xob hluav taws xob (xws li corona paug), uas tau ua dav siv nyob rau hauv lub neej tiag tiag. Cov hauv qab no piav qhia luv luv ntau Daim Ntawv Thov thiab kev ua phem ntawm hluav taws xob zoo li qub.
1 Daim Ntawv Thov ntawm hluav taws xob zoo li qub (1) Electrostatic sau cov hmoov av. Nws hais txog kev siv hluav taws xob cov txheej txheem los tshem cov hmoov av me me hauv cov roj av, cov hmoov av sau cov electrode yog hauv av, thiab DC voltage (-40 ~ -200kV) yog thov rau qhov hluav taws xob tawm hluav taws xob los ua qhov paug corona. Cov hmoov av uas muaj cov pa nkag rau hauv thaj chaw tawm hauv qab ntawm cov hmoov av sau lub tshuab hluav taws xob, thiab cov hmoov av yuav kom them tus nqi tsis zoo. Cov hmoov av tsis zoo yog adsorbed cov hmoov av sau cov hluav taws xob hauv qab qhov hluav taws xob, uas tuaj yeem tshem cov hmoov av hauv cov huab cua. Tsis tas li ntawd, thaum cov hluav taws xob tawm hluav taws xob tsis zoo, qhov tawm ntawm hluav taws xob ntawm qhov hluav taws xob zoo dua thaum cov hluav taws xob tawm hluav taws xob muaj qhov zoo, yog li lub zog hluav taws xob muaj zog dua tuaj yeem siv. Txawm li cas los xij, rau cov hmoov av nqus tsev rau kev ua huab cua sab hauv tsev, yuav kom tsis txhob muaj cov ua paug ozone, qhov zoo tshaj tawm corona feem ntau yog siv. Xyoo tsis ntev los no, kev ua haujlwm siab thiab kev txuag hluav taws xob hauv tshuab hluav taws xob tau tsim thiab siv. Piv txwv li, cov tshuab sau lub tshuab hluav taws xob tso rau hauv cov chaw tsim hluav taws xob cua sov, uas tau ua rau muaj txiaj ntsig zoo rau kev tiv thaiv huab cua.
(2) Electrostatic txau. Siv txoj ntsiab cai ntawm kev siv hluav taws xob khaws tseg, nws tuaj yeem txau kom zoo. Piv txwv li, yog tias cov xim pleev xim rau atomized thiab tsis zoo them, thaum cov khoom siv hlau npuag raug npaws rau hauv av, cov tshuaj tsuag tawg tuaj yeem txav mus raws cov kab ntawm lub zog hluav taws xob, ua kom cov xim pleev xim ruaj khov rau thaj tsam ntawm cov khoom. Electrostatic xim muaj cov zoo li nram qab no: ① cov xim tsis tshua muaj xim; Uniform thiab ruaj nchuav; Lined hloov kho khiav lag luam, thiab kev lag luam loj-loj tsim siv conveyor siv sia. Nws yog dav siv hauv kev txau cov tsheb, khoom siv hauv tsev, thiab kho lub tshuab.
(3) Electrostatic thaij duab. Electrostatic thaij duab hluav taws xob siv hluav taws xob zoo li qub los sau cov duab. Muaj ntau txoj kev. Ib qho ntawm cov txheej txheem tau piav qhia hauv qab no. Ua ntej, cov hlau phaj coated nrog selenium zaj duab xis yog muab tso rau hauv chav tsaus, thiab corona tawm yog siv los ua kom nws tau raug them. Tom qab ntawd raug nws ntsej muag. Ib feem ntawm cov yeeb yaj kiab selenium irradiated los ntawm lub teeb yuav plam nws qhov kev ua haujlwm zoo. Txau cov tshuaj pleev xim tsis muaj xim (cov xim ion) ntawm zaj duab xis selenium. Cov ntawv sau nqi zoo ntawm cov yeeb yaj kiab selenium yuav ua raws li colorant, uas yuav daim ntawv zoo raug txuas rau sab saum npoo, thiab tom qab tus qauv ntawm colorant tau theej, qhov colorant tuaj yeem kho los ntawm cua sov. Electrostatic thaij duab tseem hu ua electrophotography thiab siv dav hauv tshuab luam ntawv.
(4) Kev xaiv cov khoom siv hluav taws xob. Siv electrostatic quab yuam cais cov khoom sib cais los ntawm kev sib xyaw ntawm ob hom kev sib txuam nrog kev sib txawv sib txawv yog hu ua electrostatic sib cais. Piv txwv li, muab cov ntawv sib xyaw xyaw tso rau ntawm ib lub phaj hlau thiab siv cov tshuaj lom (corona) los them lub txim. Qaij lub phaj hlau. Lub sijhawm no, txij li cov hais nrog cov zoo conductivity poob ntau qhov them nqi hluav taws xob, kev sib xyaw ntawm cov hais thiab cov hlau phaj yog txo qis, thiab lawv poob sai sai ntawm cov hlau phaj, yog li xaiv cov ntawv pov thawj tuaj yeem nqa tawm, xws li xaiv electrostatic hauv kev ua liaj ua teb. Electrostatic sorting tau thov rau ore sorting. Kev tshem tawm ntawm cov teeb meem txawv teb chaws thaum lub sij hawm ua khoom noj thiab xaiv cov tshuaj yej nplooj.
(5) Lub cim hluav taws xob ntawm DC qhov hluav taws xob ntau. Lub van der Graaff tshuab hluav taws xob siv hluav taws xob siv corona tawm mus them lub pob hluav taws xob loj kom tsim hluav taws xob DC siab. Nws tuaj yeem siv rau cov dej xau tam sim no thiab lwm yam kev ntsuas kev ntsuas, thiab dav siv hauv cov tshuab hluav taws xob cov chaw tsim khoom thiab lub zog hluav taws xob.
(6) Kev ntsuas qhov ntsuas siab. Electrostatic voltmeters thiab cov mem tes rau cov tshuab hluav taws xob yog cov cuab yeej siv hluav taws xob zoo li qub los ntsuas cov hluav taws xob siab, thiab siv dav hauv kev ntsuas qhov ntsuas hluav taws xob ntawm lub zog hluav taws xob.
(7) Kev txuag cov roj tsheb. Kev siv hluav taws xob me me tso tawm hluav taws xob tuaj yeem hlawv cov roj tso cua sov, lub qhov cub siv roj, thiab lwm yam, thiab lub ncov paug hluav taws xob feem ntau yog kaum tawm txhiab tus (qhov hluav taws xob muaj zog yog li 1mJ). Kev tiv thaiv ntawm lub tsheb tseem siv cov hluav taws xob me me los tso hluav taws xob los ua kom cov roj hauv lub cav muaj zog. Thaum cov roj siv hluav taws xob tua, qhov siab ntawm cov nqi ntawm cov mem tes hluav taws xob yog 10-100kV.
2 Kev ntsuas tiv thaiv hluav taws xob tiv thaiv cov khoom siv hluav taws xob. Ob yam khoom yuav raug tsub nqi tom qab lawv tau sib chwv (xws li kev sib cais tom qab muab kev sib txhuam). Tom qab cov khoom tuag lossis tus neeg tsis coj raws kev cai coj mus them, muaj dej xoom me me, yog li nws tuaj yeem nyob ntev mus. Yog tias qhov kev sib cuag thiab kev sib cais rov qab, tus nqi them yuav txuas ntxiv, uas yuav ua rau muaj kev phom sij li nram no.
(1) Qhov kev raug mob los ntawm Coulomb quab yuam. Coulomb kev quab yuam tuaj yeem ua rau cov hmoov av ua raws li cov txheej txheem kev tsim khoom ntawm cov twj paj nruag xws li cov koob yees duab thiab cov khoom siv hluav taws xob, thiab nws tseem tuaj yeem ua rau cov xov paj entanglement hauv textile factories thiab entanglement ntawm textiles.
(2) Kev phom sij los ntawm kev tso tawm. Nrog rau kev tiv thaiv thiab tawg ntawm cov pa taws, qhov tawg ntawm qhov hloov pauv vim qhov hloov hluav taws xob ntawm cov roj transformer, kev sib txuas lus tsis ua hauj lwm ntawm lub dav hlau, lub suab hluav taws xob thaum lub caij tawm yuav ua rau muaj qhov tsis zoo ntawm lub khoos phis tawm, thiab kev tshwm sim thiab puas tsuaj cov duab thaij hluav taws xob thiab cov khoom siv hluav taws xob kom zoo thaum lub sijhawm kev tsim khoom. Tib neeg lub cev tau xav tsis thoob thiab lwm yam.
