Xaiv qhov raugVFDqhov loj yog ib qho ntawm cov kauj ruam tseem ceeb tshaj plaws hauv txoj haujlwm tswj lub cev muaj zog.
Ntau tus neeg yuav khoom tsuas yog phim VFD kW kev ntsuas nrog lub cev muaj zog kW. Txawm li cas los xij, qhov tseeb VFD qhov loj me rau kev siv lub cev muaj zog yuav tsum xav txog qhov ntsuas tam sim no, qhov hluav taws xob, hom kev thauj khoom, muaj peev xwm dhau thiab qhov chaw ua haujlwm.
Ntawm no yog ib qho yooj yim qhia rau distributors thiab industrial buyers.
1. Pib VFD Sizing los ntawm lub cev muaj zog ntsuas tam sim no
Thawj kauj ruam hauvVFDsizing rau daim ntawv thov lub cev muaj zog yog los xyuas lub npe ntawm lub cev muaj zog.
Cov ntaub ntawv tseem ceeb suav nrog:
- Lub cev muaj zog
- Rated voltage
- Rated tam sim no
- Rated zaus
- Tsav ceev
- Lub cev muaj zog
Ntawm cov kev txwv no,qhov ntsuas tam sim no tseem ceeb tshwj xeeb.
Ib txoj cai yooj yim yog:
VFD ntsuas cov zis tam sim no Ntau dua lossis sib npaug rau lub cev muaj zog tam sim no
Piv txwv li, ob lub 55 kW lub cev muaj zog tuaj yeem muaj cov ntsuas ntsuas sib txawv. Xaiv VFD tsuas yog raws li 55 kW thiaj li ua rau qhov tsis raug.

2. Txheeb xyuas hom Load
Qhov tseeb VFD sizing rau daim ntawv thov lub cev muaj zog kuj nyob ntawm seb lub cev muaj zog yog dab tsi.
Pumps thiab Kiv cua
Cov twj centrifugal thiab kiv cua ib txwm muaj qhov sib txawv ntawm -torque yam ntxwv.
Rau cov qauv qis-voltage twj thiab kiv cua, cov neeg yuav khoom tuaj yeem xav txog RENLE RNB1000 Tsawg Voltage Drive.
RENLE teev cov RNB1000 rau cov ntawv thov suav nrog cov kiv cua, twj tso kua mis, cov cuab yeej siv tshuab, ntim khoom thiab cov khoom siv thauj khoom. Cov koob txhawb nqa V / F thiab vector tswj.
Conveyors, Mixers thiab Heavy Loads
Conveyors, mixers thiab lwm yam tas li -torque loads yuav xav tau siab dua pib torque thiab overload muaj peev xwm.
Rau cov ntawv thov no, cov neeg yuav khoom tuaj yeem xav txog RENLE RNB2000 Tsawg Voltage Variable Frequency Drive.
RNB2000 txhawb nqa asynchronous thiab ruaj khov hlau nplaum synchronous lub cev muaj zog thiab muab vector- tswj kev xaiv rau kev thov kev lag luam ntau dua.
3. Tshawb xyuas VFD Overload Capacity
Lub cev muaj zog tam sim no nyob rau hauv ib txwm ua haujlwm tsuas yog ib feem ntawm cov txheej txheem sizing.
Qee daim ntawv thov xav tau tam sim no ntxiv thaum:
- Hnyav-load pib
- Kev nrawm nrawm
- Sudden load hloov
- Nquag pib thiab nres
- Tsawg-ceev siab- ua haujlwm torque
Vim li no,VFDsizing rau lub cev muaj zog yuav tsum muaj xws li qhov yuav tsum tau muaj peev xwm overload.
Piv txwv li, RENLE's RNB1000 specification teev cov peev txheej dhau ntawm 150% ntsuas tam sim no rau 60 vib nas this, 180% rau 10 vib nas this thiab 200% rau 1 thib ob.
Lub conveyor nrog ib tug hnyav pib load tej zaum yuav xav tau ib tug sib txawv xaiv los ntawm ib tug centrifugal kiv cua, txawm hais tias ob motors muaj tib kW ntsuam xyuas.
4. Sib piv qhov hluav taws xob
CovVFDvoltage yuav tsum phim lub cev muaj zog thiab fais fab mov.
Yam tsawg-voltage systems muaj xws li:
- 220–240 V
- 380–415 V
- 440–480 V
Tsis txhob xaiv VFD raws li lub zog ib leeg yam tsis tau lees paub qhov voltage.
Rau cov qauv qis-voltage daim ntawv thov, RNB1000 npog qhov dav qis -voltage range thiab muaj los ntawm 0.75 kW txog 500 kW raws li RENLE cov ntaub ntawv khoom tam sim no.
Rau nruab nrab-voltage motors xws li 6 kV lossis 10 kV systems, nruab nrab -voltage VFD yuav tsum raug ntsuas es tsis txhob siv cov pa qis -voltage drive.
5. Xav txog qhov kub thiab qhov siab
Lwm qhov feem ntau tsis nco qab hauvVFDsizing rau lub cev muaj zog yog lub installation ib puag ncig.
Qhov kub ambient kub thiab qhov siab siab tuaj yeem cuam tshuam rau lub peev xwm muaj peev xwm ntawm lub tsav.
Piv txwv li, RENLE qhia txog qhov yuav tsum tau ua rau RNB1000 thaum ambient kub tshaj 40℃thiab thaum installation qhov siab tshaj 1,000 meters.
Yog li ntawd, buyers yuav tsum ib txwm muab:
Ambient kub + altitude + installation ib puag ncig
thaum thov VFD hais.
Quick VFD Sizing Piv txwv
Xav tias cov ntaub ntawv lub cev muaj zog yog:
Lub cev muaj zog: 55 kW
Lub cev muaj zog: 380V
Rated tam sim no: 108 A
Daim ntawv thov: centrifugal twj tso kua mis
RENLE's RNB1000 xaiv lub rooj teev cov RNB1055G/075P nrog cov zis- qhov ntsuas tam sim no ntawm 115 A rau qhov sib thooj 55 kW hnyav-load rating.
Txij li thaum lub cev muaj zog ntsuas tam sim no yog 108 A, qhov no dhau los ua tus qauv ua tau los ntsuas.
Txawm li cas los xij, qhov kev xaiv zaum kawg yuav tsum tseem lees paub:
Hom load tiag
Cov kev cai pib
Overload xav tau
Ambient kub
Qhov siab
Yuav tsum tau tswj kev ua haujlwm
Qhov no yog vim li casVFDsizing rau lub cev muaj zog yuav tsum tsis txhob nyob ntawm kW ib leeg.
