Ib tug sib txawv zaus tsav (VFD) yog ib tug sophisticated lub cev muaj zog tswj system. Lub VFD tswj qhov ceev ntawm lub tshuab hluav taws xob los ntawm qhov sib txawv ntawm qhov voltage thiab zaus uas muab rau lub cev muaj zog. Lub tshuab VFD tuaj yeem hloov cov kev tswj hwm txhua yam hauv cov tshuab xws li li qub ntawm cov twj lossis louvers rau cov kiv cua. Thaum ua haujlwm VFD tsuas yog xa lub zog tsim nyog rau lub cev muaj zog kom ua tau raws li lub sijhawm tiag tiag ntawm qhov system. Lub VFD yuav kho lub cev muaj zog kom phim cov kev hloov pauv hauv cov kev xav tau ntawm lub cev. Cov tsav yuav siv tau raws li theem converters, converting ib theem input rau hauv peb theem inverter tso zis.
Qhov zoo ntawm VFD
Kev txuag hluav taws xob
Kev txuag hluav taws xob yog cov txiaj ntsig tseem ceeb ntawm VFD vim tias cov khoom siv ua haujlwm raws li qhov yuav tsum tau ua. Piv txwv tias lub tshuab ac blower ua haujlwm raws li temp yog tias qhov kub siab ces lub tshuab yuav txav mus li qub rpm, yog tias qhov kub qis ces lub tshuab yuav txav qeeb. Qhov ceev ntawm blower yog tswj los ntawm VFD raws li temp.
Kev tiv thaiv
VFD tseem muab kev tiv thaiv los ntawm overload, dhau voltage thiab theem poob. Cov hom kev ua txhaum no muaj nyob rau VFD tam sim ntawd nres lub hwj chim.
Txhim kho cov neeg kho tshuab lub neej
Lub cev muaj zog pib thiab nres nyob rau hauv smoothly tsis muaj jerks yog li tsis muaj kev ntxhov siab txhua yam muaj. Lub neej ntawm txhua yam khoom siv yog nce xws li bearings, hav txwv yeem thiab lwm yam.
Ib qho yooj yim installation
Lub VFD yog cov tuam txhab ua ntej-programmed yog li nws yog qhov tsawg kawg nkaus yuav tsum tau xaim. Vim yog qhov tsawg kawg nkaus thaiv, cov txheej txheem ntawm kev teeb tsa yooj yim heev.
Kev saib xyuas tsawg
Vim tias kev ua haujlwm du ntawm lub tshuab hluav taws xob lossis lub cev muaj zog, lub neej ntawm cov khoom siv kho tshuab, kev rwb thaiv tsev ntawm windings thiab cables tau txhim kho. Lub neej ntawm cov khoom yuav nce ntxiv ces kev saib xyuas ntawm cov cuab yeej yuav raug txo.
Mos pib
Thaum lub cev muaj zog pib ces nws yuav siv sij hawm ntau ntawm tam sim no thiab nres nrog jerks. VFD kuj ua haujlwm zoo li lub tshuab hluav taws xob zoo li lub cev muaj zog pib thiab nres kom zoo yam tsis muaj jerk lossis dhau tam sim no.
Qhov hluav taws xob qhov chaw inverter (VSI):VSI yog hom ntau tshaj plaws, qhov twg qhov hluav taws xob dc tseem nyob tas li, thiab qhov tso zis ntau zaus hloov pauv los ntawm kev hloov cov mem tes dav.
Tam sim no qhov chaw inverter (CSI):Hauv CSI, qhov tso zis tam sim no tseem nyob tas li, thiab qhov zaus yog tswj los ntawm kev hloov cov mem tes dav.
Pulse width modulation (PWM) VFD:PWM VFD yog qhov nthuav dav tshaj plaws, siv cov pulses siab los tswj lub cev muaj zog ceev thiab qhov hluav taws xob.
Matrix converter VFD:Cov VFD siab heev no siv lub matrix ntawm semiconductor keyboards ncaj qha hloov ac fais fab mus rau qhov xav tau zaus thiab voltage.
Daim ntawv thov koj tab tom khiav yuav tsum tau tswj kom meej:
Yog tias du, seamless tswj yog qhov tsim nyog rau koj daim ntawv thov, lossis yog tias koj xav tau ntau lub cev muaj zog ua haujlwm hauv sync, VFD tuaj yeem ua tiav qhov no. VFD txawm muaj kev ua haujlwm siab rau kev tswj cov twj, kiv cua thiab compressors.
Koj daim ntawv thov muaj cov khoom sib txawv:
Qhov no zoo li yuav tshwm sim tsis tu ncua nrog hvac thiab siv cov twj tso kua mis. VFD muaj peev xwm khiav lub cev muaj zog ntawm qhov txo qis, uas tuaj yeem txuag tau ib tuj ntawm lub zog.
Koj daim ntawv thov cuam tshuam nrog kev pib thiab nres tsis tu ncua, ib yam li cov ntaub ntawv nrog qee qhov conveyor.
Daim ntawv thov:
VFD tuaj yeem ua tau raws li cov pib muag muag, thiab tuaj yeem maj mam nce lawv cov motors mus rau qhov xav tau ceev. Thaum nws los txog rau kab hluav taws xob, lub cev muaj zog feem ntau yuav pib ntawm qhov nrawm uas tuaj yeem ua rau muaj kev ntxhov siab thiab lwm yam teeb meem.
Koj lub cev muaj zog khiav ntawm qhov nrawm nrog cov zis tawm throttled:
Throttling cov zis ntawm koj lub cev muaj zog yog qhov tsis txaus ntseeg tsis txaus ntseeg - yog li nws tau qhia kom siv lub tsav hauv qhov xwm txheej no, vim nws yuav pab tau tus nqi tseem ceeb thiab txuag hluav taws xob.
Vim li cas VFD yog qhov zoo tagnrho haum rau kev siv cov twj tso kua mis?
VFD tswj vaj huam sib luag (lwm lub npe hu ua ac drives, inverters lossis hloov pauv ceev tsav) yog cov cuab yeej siv lub cev muaj zog siv los tswj ac lub cev muaj zog thiab lub zog, ua tiav los ntawm kev hloov cov khoom siv hluav taws xob thiab zaus hauv cov tshuab hluav taws xob.Cov VFD no tuaj yeem siv rau hauv ob qho tib si me thiab loj. cov khoom siv, txawm li cas los xij, lawv feem ntau siv hauv cov tshuab loj xws li compressors, conveyers, thiab drilling & siv cov ntawv thov.

Rectifier
Lub rectifier hloov cov khoom siv tam sim no (AC) mus rau qhov tam sim no ncaj qha (DC).
Nruab nrab Circuit Court
DC cov khoom siv mus los ntawm lub voj voog no siv cov capacitors thiab inductors ua ke.
Inverter
Lub inverter converts DC mov los ntawm nruab nrab Circuit Court rau hauv alternating tam sim no (AC).
Control unit
Qhov no yog qhov tseem ceeb ntawm lub plawv ntawm VFD, uas saib xyuas txhua txoj haujlwm.
5 Cov kauj ruam los daws teeb meem VFD
Tshawb xyuas lub cev puas tsuaj
Saib seb puas muaj cov cim qhia tias cov pa taws ua khawv koob tsis tau tso tawm. Tshawb xyuas lub cuab yeej thiab nws qhov chaw nyob ib puag ncig kom ntseeg tau tias tsis muaj qhov cim ntawm cov kua qaub uas taw qhia rau cov khoom siv hluav taws xob tsis ua haujlwm. Yog hais tias muaj cov cim qhia tias ib yam dab tsi tau combusted, kaw lub hwj chim los thiab ceeb toom lub hwj chim yuav tsum tau muab ib tug hloov.
Tshawb xyuas lub zog tuaj
Muaj lub hwj chim pub rau VFD thiab tam sim no yog lub sijhawm los xyuas kom meej tias tsis muaj dab tsi cuam tshuam cov khoom siv no. Nws yog ib qho tseem ceeb los xyuas cov khoom xws li fuses, Circuit Court breakers thiab disconnects upstream kom paub tseeb tias lawv tsis zoo thiab npaj ua haujlwm. Cov ntsuas tsim nyog yuav tsum tau siv thiab tsis txhob sim yam tsis muaj kev cob qhia kom raug thiab ua raws li koj lub tuam txhab cov cai tswj kev nyab xeeb. Rau cov peev txheej ntxiv ntawm kev sim cov khoom siv hluav taws xob, cov peev txheej pom ntawm no yuav pab tau.
Validate txhaum cai
Fault codes yog ib txoj hauv kev zoo los kawm seb tus tsav puas tau ntsib thiab ua rau muaj teeb meem. Thaum lawv sib txawv ntawm cov chaw tsim khoom rau cov chaw tsim khoom muaj qee qhov ua txhaum cai uas tuaj yeem taw qhia rau cov teeb meem hauv qab koj tab tom ntsib. Thawj faults yog:
● Overvoltage -DC tsheb npav ntsuas qhov hluav taws xob siab dua li qhov yuav tsum tau ua
● Overcurrent –lub cev muaj zog tam sim no tshaj qhov tau txais fla los ntawm lub npe lub npe
● Overtemperature –tsav / lub cev muaj zog overheating
● Lub cev muaj zog tshaj -lub cev muaj zog khiav ntawm qib siab dua li tsim los rau lub sijhawm ntev
