Cov kev cai hloov ceev ceev feem ntau yog hais txog cov txheej txheem electromechanical: zaus hloov pauv ceev tswj induction lub cev muaj zog, zaus converter, programmable maub los thiab lwm yam khoom siv ntse, davhlau ya nyob twg actuators thiab tswj software, thiab lwm yam, ua ib qho qhib-voj lossis kaw-voj AC ceev tswj qhov system.Hom kev tswj ceev no yog hloov cov txheej txheem tswj kev ceev ceev thiab DC ceev tswj cov txheej txheem hauv qhov xwm txheej tsis tau pom dua, uas ua rau muaj txiaj ntsig zoo ntawm cov tshuab automation thiab kev ua haujlwm ntau lawm, thiab ua rau cov cuab yeej ua kom me me thiab txawj ntse.
Saib ntawm kev siv lub zog ntawm txhua lub cev muaj zog hauv cov ntawv thov kev lag luam, kwv yees li 70% ntawm cov motors yog siv hauv kiv cua thiab twj tso kua mis.Cov txiaj ntsig ntawm kev txuag hluav taws xob thiab kev txo qis emissions rau cov khoom no yog qhov pom tseeb: cov txiaj ntsig kev lag luam loj thiab cov txiaj ntsig kev noj qab haus huv.Tsuas yog raws li lub hom phiaj saum toj no, AC lub cev muaj zog hloov pauv ceev tswj tau dav siv.Piv txwv li, nyob rau hauv lub inverter cua txias, thaum lub kub teem los ntawm lub tshuab cua txias yog txo, nws tsuas yog tsim nyog los tswj lub ceev ntawm lub cev muaj zog kom txo tau thiab txo cov zis tsav zog.
Ntxiv nrog rau kev txuag hluav taws xob thiab ua kom yooj yim rau kev nyiam thiab siv tau, qhov sib txawv ntawm qhov ceev-tswj asynchronous motors muaj qhov zoo ntawm kev pib muag muag, thiab tsis tas yuav tshuaj xyuas qhov pib ua haujlwm.Tib qhov teeb meem tseem ceeb uas yuav tsum tau daws yog: kev hloov pauv ntawm lub cev muaj zog rau lub zog tsis yog sine yoj yuav tsum tau txhim kho.
Frequency converter ua hauj lwm hauv paus ntsiab lus
Cov zaus hloov pauv peb siv feem ntau yog siv AC-DC-AC hom (VVVF zaus hloov pauv lossis vector tswj zaus hloov pauv).Ua ntej, lub zog zaus AC lub zog hloov mus rau DC lub zog los ntawm lub tshuab hluav taws xob, thiab tom qab ntawd lub zog DC hloov mus rau AC nrog cov zaus tswj tau thiab qhov hluav taws xob.lub zog los muab lub cev muaj zog.Lub Circuit Court ntawm lub zaus converter feem ntau yog tsim los ntawm plaub ntu: rectification, intermediate DC txuas, inverter thiab tswj.Lub rectification ib feem yog ib tug peb-theem choj uncontrolled rectifier, lub inverter ib feem yog ib tug IGBT peb-theem choj inverter, thiab cov zis yog PWM waveform, thiab qhov nruab nrab DC txuas yog lim, DC zog cia thiab buffering reactive zog.
Kev tswj hwm zaus tau dhau los ua cov txheej txheem tswj kev ceev ceev, uas tuaj yeem siv dav hauv kev sib kis tsis muaj zog hauv ntau yam lag luam.Tshwj xeeb tshaj yog nrog kev nthuav dav ntawm daim ntawv thov ntawm zaus converters nyob rau hauv lub tshav pob ntawm kev lag luam tswj, kev siv cov zaus hloov dua siab tshiab motors tau nce zuj zus.Nws tuaj yeem hais tias vim qhov zoo tshaj plaws ntawm zaus hloov lub cev muaj zog hauv kev hloov pauv zaus tswj cov motors zoo tib yam, txhua qhov chaw hloov pauv zaus siv, peb tsis yooj yim pom daim duab ntawm lub zog hloov pauv zaus.
Qhov kev ntsuas qhov sib txawv ntawm lub cev muaj zog feem ntau yuav tsum tau siv los ntawm lub tshuab hloov zaus.Txij li thaum cov zis zaus ntawm lub zaus converter muaj ntau qhov sib txawv, thiab cov zis PWM yoj muaj cov kev sib raug zoo, cov khoom siv hluav taws xob thiab lub ntsuas hluav taws xob tsis tuaj yeem ua tau raws li qhov xav tau ntawm kev ntsuas.Frequency conversion zog analyzer thiab zaus hloov dua siab tshiab fais fab kis, thiab lwm yam.
Tus qauv ntsuas lub cev muaj zog yog ib hom kev sim tshiab uas tau tsim los rau lub zog ntawm kev txhim kho lub cev muaj zog hauv kev teb rau kev txuag hluav taws xob thiab txo qis emission.Cov qauv kev ntsuas lub cev muaj zog ua qauv tsim thiab ntsuas cov txheej txheem nyuaj, txhim kho kev ntseeg tau ntawm lub cev, ua kom yooj yim rau kev teeb tsa thiab kev debugging, thiab txo cov nqi system.
Frequency conversion tshwj xeeb lub cev muaj zog nta
Class B kub nce tsim, F chav kawm ntawv rwb thaiv tsev tsim.Kev siv cov ntaub ntawv rwb thaiv tsev polymer thiab lub tshuab nqus tsev siab impregnated varnish tsim cov txheej txheem thiab kev siv cov txheej txheem rwb thaiv tsev tshwj xeeb ua rau cov hluav taws xob winding rwb thaiv tsev tiv taus qhov hluav taws xob thiab lub zog ua haujlwm zoo heev, uas yog txaus rau kev ua haujlwm siab ceev ntawm lub cev muaj zog thiab ua haujlwm siab. -frequency tam sim no cuam tshuam thiab voltage ntawm lub inverter.Kev puas tsuaj rau rwb thaiv tsev.
Lub zog hloov pauv zaus muaj qhov sib npaug zoo, thiab qib kev vibration yog R-theem.Lub machining precision ntawm txhua yam khoom yog siab, thiab tshwj xeeb high-precision bearings yog siv, uas yuav khiav ntawm kev kub ceev.
Kev hloov pauv zaus lub cev muaj zog txais yuav tsum tau ua kom cua thiab cua sov dissipation system, thiab tag nrho cov axial flow kiv cua yog ultra-ntev, lub neej ntev, thiab muaj zog cua.Guarantee cov cua kub dissipation ntawm lub cev muaj zog ntawm txhua qhov ceev, thiab paub txog kev kub ceev lossis qis-ceev ua haujlwm ntev.
Piv nrog rau cov tsoos sib txawv zaus lub cev muaj zog, nws muaj qhov dav dav dav thiab tsim qauv zoo dua.Qhov tshwj xeeb magnetic teb tsim ntxiv suppresses high-order harmonic magnetic teb kom tau raws li cov qauv tsim ntawm broadband, lub zog txuag thiab tsis tshua muaj suab nrov.Nws muaj ntau yam tsis tu ncua torque thiab lub zog ceev tswj cov yam ntxwv, ruaj khov ceev tswj, thiab tsis muaj torque ripple.
Nws muaj qhov zoo parameter txuam nrog ntau zaus converters.Kev koom tes nrog vector tswj, nws tuaj yeem paub txog xoom-ceev puv-torque, tsawg zaus high-torque thiab high-precision ceev tswj, txoj hauj lwm tswj thiab ceev ceev dynamic teb.
