Thaum Xaiv VF Tswj VFD thiab Vector Tswj VFD, Ntau Yam Yuav Tsum Tau Txiav Txim?
Thaum txiav txim siab ntawm V / f tswj VFD thiab vector tswj VFD, ntau yam tuaj rau hauv kev ua si. Ua ntej, xav txog hom lub cev muaj zog thiab nws cov kev xav tau. Qee lub cev muaj zog tuaj yeem tau txais txiaj ntsig ntau dua los ntawm qhov raug muab los ntawm vector tswj, thaum lwm tus tuaj yeem ua haujlwm zoo nrog V / f tswj.
Tom ntej no, xav txog cov yam ntxwv ntawm lub load lub cev muaj zog yuav tsav. Hnyav loads lossis cov uas yuav tsum tau ceev ceev thiab torque tswj yuav lean ntawm vector tswj.
Cov kev xav tau ntawm kev ua tau zoo kuj ua lub luag haujlwm tseem ceeb. Cov ntawv thov xav tau qhov raug siab ceev lossis lub sijhawm teb ceev feem ntau nyiam vector tswj vim nws lub peev xwm zoo tshaj plaws.
Kev txwv tus nqi kuj tseem ceeb heev. Thaum vector tswj muaj kev ua tau zoo, nws feem ntau los nrog kev nqis peev ntau dua piv rau V / f tswj. Nws yog ib qho tseem ceeb kom sib npaug cov kev xav tau ntawm kev ua haujlwm nrog kev xav txog nyiaj txiag.
Kev nce qib hauv thev naus laus zis thiab cov qauv kev lag luam tseem cuam tshuam rau kev txiav txim siab. Raws li kev tswj hwm vector ua tau yooj yim dua thiab tsim nyog, nws txoj kev saws me nyuam nyob rau hauv ntau yam kev lag luam txuas ntxiv mus ntxiv, uas tau tsav los ntawm qhov kev thov kom ua tau zoo thiab ua haujlwm tau zoo.
Thaum kawg, kev xaiv ntawm V / f tswj thiab vector tswj yog nyob ntawm kev soj ntsuam kom zoo ntawm cov xwm txheej no kom ntseeg tau tias txoj kev tswj lub cev muaj zog ua raws li cov cai tshwj xeeb ntawm daim ntawv thov.
VF tswj hom ntawm VFD hauv daim ntawv thov kiv cua
Nws nyob ntawm daim ntawv thov. Yog tias nws yog kiv cua me me lossis daim ntawv thov yooj yim mus nrog V / F. Raws li txoj cai, V / F yuav tsis raug, qis dua tam sim no thiab nyiaj tsawg. AV/F tsuas yog tso tawm cov zaus uas tau hais tseg thiab tsis mob siab txog kev hloov pauv lossis plam. Yog hais tias nws yog ib tug centrifugal kiv cua ces nws yuav lub cube txoj cai loaded. HP yuav tsum tau nce lossis txo mus rau lub voos xwmfab ntawm qhov ceev. Lub cev muaj zog yuav pib nrog tsis muaj load thiab lub load nce mus rau 100% ntawm 100% ceev. Siab pib / tawg tawm torque feem ntau tsis tas yuav tsum tau.
Raws li qhov tshwm sim ntawm lub cev muaj zog thiab qhov sib txawv ntawm cov tsav tsheb feem ntau tsis tas yuav muaj kev pabcuam ntxiv. Feem ntau ntawm cov ntawv thov no tsis tas yuav muaj qhov raug siab ceev / khiav kev cai yog li v / f yog txhua yam uas xav tau. Yog tias tus kiv cua nyob hauv qhov chaw sim (xws li lub qhov cua cua) thiab nws yuav tsum tau tswj xyuas qhov ntws los yog siab kom raug rau lub sijhawm ntev thaum ntsuas ntsuas ces yuav tsum tau siv hom vector tswj.
