Suab nrov yog ib qho kev phom sij rau kev ua haujlwm hauv cov chaw ua zaub mov.Los ntawm vibrating panels mus rau txhua yam rotors, stators, kiv cua, conveyors, twj, compressors, palletisers thiab diav rawg nqa.Tsis tas li ntawd, qee qhov kev cuam tshuam tsis zoo ntawm lub suab tuaj yeem cuam tshuam qhov kev ua tau zoo ntawm kev tshawb pom hlau thiab cov khoom siv ntsuas ntsuas.Qhov tseem ceeb tshaj plaws yog lub ntiaj teb / av loops thiab hluav taws xob tsav tsheb.
Jason Lu, Technical Applications Support ntawm Fanchi Technology, tshuaj xyuas qhov ua rau thiab qhov cuam tshuam ntawm cov kev cuam tshuam no thiab cov kev ntsuas uas tuaj yeem siv los txo cov suab nrov cuam tshuam.
Ntau yam txiav txim siab theoretical rhiab heev ntawm ahlau ntes.Ntawm lawv yog qhov aperture loj (qhov me me ntawm qhov aperture, qhov me me ntawm cov hlau uas tuaj yeem ntes tau), hom hlau, cov khoom siv, thiab kev taw qhia ntawm cov khoom thiab cov khoom paug thaum nws dhau los ntawm lub ntes.Txawm li cas los xij, ib puag ncig ib puag ncig, xws li kev cuam tshuam hauv huab cua - zoo li qub, xov tooj cua lossis lub ntiaj teb loops - kev co, piv txwv li txav hlau, thiab qhov kub thiab txias, xws li qhov cub lossis qhov cub txias, kuj tuaj yeem cuam tshuam kev ua haujlwm.
Cov yam ntxwv tshwj xeeb zoo li Noise Immunity Structure thiab cov ntxaij lim dej digital uas muaj nyob rau ntawm lub tuam txhab cov khoom siv hlau digital tuaj yeem cuam tshuam qee qhov kev cuam tshuam no, uas tej zaum yuav txwv tsis pub txo cov qib rhiab heev ntawm tes.
Lub ntsiab qhov chaw ntawm electromagnetic cuam tshuam thiab xov tooj cua zaus cuam tshuam muaj xws li hluav taws xob lub cev muaj zog tsav - piv txwv li qhov sib txawv zaus tsav thiab servo motors, lub cev muaj zog cables tsis shielded kom raug, ob txoj kev xov tooj cua, xws li walkie talkies, hauv av loops, hluav taws xob contactors thiab static paug.
Cov lus qhia hauv av
Qhov kev sib tw thoob plaws Fanchi engineers ntsib dhau los ua qhov teeb meem tshwm sim hauv cov khoom noj khoom haus.Tshwj xeeb tshaj yog nyob rau qhov kawg-rau-kawg cov kab ua ke nrog cov neeg hlau, hnab ntim khoom, ntws qhwv thiab conveyors.Cov kev cuam tshuam ntawm electromagnetic cuam tshuam tuaj yeem cuam tshuam qhov kev ua haujlwm ntawm cov khoom siv hlau uas ua rau muaj kev kuaj pom tsis tseeb, tsis lees paub qhov tseeb, thiab ua rau muaj kev pheej hmoo ntawm kev nyab xeeb khoom noj.
"Cov tshuab ntim khoom xws li cov ntaub qhwv cov ntaub qhwv thiab cov khoom siv conveyor yuav yog qhov ua rau muaj teeb meem loj tshaj plaws hauv av vim yog hnav tawm lossis xoob fixings thiab cov menyuam yaus" hais tias Jason.
Kev tawm tswv yim hauv av tshwm sim thaum twg cov khoom siv hlau nyob ze rau ntawm lub ntsuas ntsuas txuas los ua ib lub voj voog, piv txwv li cov menyuam tsis siv neeg uas tsis tau raug insulated ntawm ib sab ntawm tus ncej sau ntawv Jason.Nws piav qhia tias: “Ib daim ntawv voj uas tso cai rau cov hluav taws xob cuam tshuam kom ntws.Qhov no nyob rau hauv lem tuaj yeem ua rau lub suab nrov uas cuam tshuam cov teeb liab nrhiav pom hlau thiab tuaj yeem ua rau muaj teeb meem ua haujlwm, xws li cov khoom tsis raug lees paub. "
Xov tooj cua
Qhov susceptibility ntawm ahlau ntesrau magnetic los yog electromagnetic cuam tshuam yog nyob ntawm nws rhiab heev thiab nrhiav tau bandwidth.Yog tias ib lub tshuab ntes hlau tau xa cov zaus zoo sib xws mus rau lwm qhov hauv qhov chaw ua haujlwm tsis khoom, lawv yuav hla kev sib tham yog tias nyob ze ua ke.Txhawm rau tiv thaiv qhov no tshwm sim, Fanchi pom zoo kom sib nrug ntawm cov hlau ntes tsawg kawg yog plaub meters sib nrug, los yog ua rau cov hlau ntes ntau zaus kom lawv tsis ncaj nraim.
Ntev thiab nruab nrab nthwv dej transmitters - xws li walkie talkies - tsis tshua muaj teeb meem.Muab lawv tsis cranked siab dhau lawm los yog siv nyob ze heev rau cov hlau detector coil receiver.Rau kev nyab xeeb, khaws cov walkie talkies ua haujlwm ntawm peb watts lossis tsawg dua.
Cov khoom siv sib txuas lus digital, piv txwv li cov xov tooj ntse, emit tsawg dua suab cuam tshuam, sau Jason."Nws nyob ntawm seb lub coil rhiab npaum li cas thiab dua qhov sib thooj ntawm cov cuab yeej rau lub ntsuas hlau.Tab sis cov khoom siv txawb tsis tshua muaj nyob ntawm tib lub bandwidth raws li cov khoom siv.Yog li nws tsis tshua muaj teeb meem.

Kev daws teeb meem zoo li qub
Cov teebmeem EMI tuaj yeem cuam tshuam tsis zoo rau kev ua haujlwm ntawmhlau ntes
Txhua qhov kev txav me me hauv kev tsim kho tshuab ntawm cov hlau ntes uas ua rau muaj kev vibrations me me tuaj yeem ua rau tsis lees paub qhov tseeb.Kev tsim hluav taws xob zoo li qub feem ntau yuav tshwm sim ntawm lub ntiajteb txawj nqus thiab ntsug hlau tshawb nrhiav daim ntawv thov yog tias cov kav dej tsis tau ua kom raug, hais Jason.
Nrhiav ib lub tshuab ntes hlau rau hauv pem teb mezzanine tuaj yeem tsim teeb meem.Tshwj xeeb tshaj yog cov neeg kho tshuab suab nrov infractions, tshwj xeeb tshaj yog los ntawm chutes, hoppers thiab conveyors.Jason hais tias "Cov khoom siv hlau uas tau hloov mus rau cov khoom ntub dej feem ntau tseem ceeb dua rau hom kev vibration thiab suab nrov," hais Jason.
Txhawm rau kom ntseeg tau qhov kev ua tau zoo tshaj plaws thiab tsis txhob muaj kev vibration, tag nrho cov kev txhawb nqa thiab cov khoom siv tsis lees paub yuav tsum tau welded.Fanchi kuj tsis txhob siv cov khoom siv los tiv thaiv zoo li qub, vim qhov no kuj tuaj yeem txo cov hlau ntes kev ua haujlwm.
Nrhiav qhov chaw ntawm qhov teeb meem sai thiab raug yog qhov tseem ceeb, vim tias kev cuam tshuam tsis tu ncua ntawm cov kab ua haujlwm tsis siv neeg tuaj yeem ua rau muaj kev cuam tshuam txog kev pabcuam.Fanchi tuaj yeem siv lub tshuab sniffer kom nrawm nrawm ntawm qhov chaw nyob ze EMI thiab RFI.Zoo li lub kav hlau txais xov, cov disc dawb ntsuas wavelengths thiab tuaj yeem nyob nrawm ntawm qhov chaw sib tw sib tw.Nrog rau cov ntaub ntawv no, engineers tuaj yeem tiv thaiv, cuam tshuam lossis hloov txoj hauv kev ntawm cov emissions.
Fanchi kuj tseem muaj cov kev xaiv los hloov kho mus rau lub siab voltage oscillator.Rau cov chaw tsim khoom nrov heev, suav nrog cov nroj tsuag uas siv tau zoo heev, qhov kev daws teeb meem no ua rau Fanchi hlau ntes lub suab nrov nrov.
Cov neeg siv-phooj ywg
Fanchi nta xws li automated ib zaug dhau kev kawm thiab calibration tuaj yeem xa cov txheej txheem raug teeb tsa hauv vib nas this thiab tshem tawm tib neeg yuam kev.Tsis tas li ntawd, cov qauv tsim muaj suab nrov hauv kev tiv thaiv kab mob - suav nrog rau txhua tus qauv ntawm Fanchi digital hlau ntes, tuaj yeem txo qhov cuam tshuam ntawm cov suab nrov sab nraud, rov ua rau cov khoom tsis raug tsawg dua.
Jason xaus lus tias: “Nws tsis yooj yim sua kom tshem tawm cov suab nrov cuam tshuam hauv qhov chaw tsim khoom.Txawm li cas los xij, los ntawm kev ua raws li cov kev ceev faj no thiab nrhiav cov kws tshaj lij kev taw qhia, peb cov kws tsim khoom tuaj yeem txo qhov EMI cov lus tawm tswv yim thiab ua kom cov hlau tshawb pom kev ua tau zoo thiab tsis muaj kev cuam tshuam.
