Precision Motor Control yokhala ndi ma VFD apamwamba kwambiri ochokera ku Global Brands
VFD ndi chiyani?
A Variable Frequency Drive (VFD) ndi chida chofunikira chowongolera mafakitale chomwe chimagwiritsidwa ntchito kuwongolera liwiro ndi torque ya ma mota a AC posintha ma frequency ndi ma voliyumu amagetsi. Ma VFD amawonjezera mphamvu zamagetsi, amachepetsa kupsinjika kwamakina, ndikuwongolera magwiridwe antchito pazinthu zosiyanasiyana, kuphatikiza mapampu, mafani, ma conveyors, ndi makina a HVAC.
Timapereka ma VFD odalirika, apamwamba kwambiri kuchokera kumakampani otsogola padziko lonse lapansi monga Siemens, Schneider, Yaskawa,ndi ABB, kuonetsetsa kudalirika, ntchito,ndi kukhazikika kwa nthawi yayitali pazosowa zanu zamafakitale. Kaya za zochita zokha, kupulumutsa mphamvu, kapena kuwongolera bwino kwagalimoto, katundu wathu amakumana ndi miyezo yapamwamba kwambiri yamakampani.
Zigawo Zazikulu za VFD System
Magalimoto a AC
Zomwe Iwo Ali: Ma AC Drives, omwe amadziwika kuti Variable Frequency Drives (VFDs), amasintha liwiro ndi torque ya ma AC motors posintha ma frequency ndi voteji yamagetsi, amapereka kuwongolera liwiro, kupulumutsa mphamvu, ndikuchepetsa kuvala kwagalimoto ndikuyenda bwino. Ntchito: Zabwino pamapampu, mafani, zotengera, ndi makina a HVAC omwe amafunikira liwiro losinthika
Mphamvu Yovotera: Kufanana ndi mphamvu ya injini.
Mphamvu yamagetsi: Imagwirizana ndi mphamvu yamagetsi.
Zolowetsa: 1-gawo kapena 3-gawo, kutengera dongosolo.
Magalimoto a DC
Zomwe Iwo Ali: Magalimoto a DC amayang'anira liwiro la mota ya DC ndi torque posintha ma voliyumu omwe amaperekedwa ku mota, amapereka zosintha zowongoka, zolondola pazantchito zina. Mapulogalamu: Amagwiritsidwa ntchito m'makina akale, ma elevator, ma cranes, ndi makina omwe amafunikira torque yamphamvu.
Zovoteledwa Panopa: Pazipita panopa (mwachitsanzo, 10A kuti 1000A) pagalimoto akhoza kupereka.
Kuvoteledwa kwa Voltage: Mphamvu yamagetsi ya DC (mwachitsanzo, 180V, 500V) yamagalimoto.
Mphamvu yamagetsi: Mphamvu yamagetsi ya AC (mwachitsanzo, 230V, 400V).
Zolowetsa: Kulowetsa kwa gawo limodzi kapena 3-gawo, kutengera kuyendetsa.
NDI VSD
Zomwe Iwo Ali: AC VSDs ndi dzina lina la AC Drives kapena VFDs, poyang'ana luso lawo losintha liwiro la mota, amawongolera magwiridwe antchito agalimoto ndikugwiritsa ntchito mphamvu popewa kugwira ntchito mwachangu. Mapulogalamu: Odziwika pamakina odzipangira okha, opanga, komanso osagwiritsa ntchito mphamvu zamagetsi
Mphamvu Yovotera: Kufanana ndi mphamvu ya injini.
Mphamvu yamagetsi: Imagwirizana ndi mphamvu yamagetsi.
Zolowetsa: 1-gawo kapena 3-gawo, kutengera dongosolo.
Single gawo Drives
Zomwe Iwo Ali: Ma VFD awa amapangidwira ma motors agawo limodzi a AC, omwe nthawi zambiri amapezeka m'magawo ang'onoang'ono, amabweretsa kuwongolera liwiro pamagalimoto agawo limodzi, kupititsa patsogolo magwiridwe antchito pamakina ophatikizika. Ntchito: Zabwino kwa mafani akunyumba, zowombera, ndi mapampu ang'onoang'ono
Mphamvu Yovotera: Nthawi zambiri kutsika, mwachitsanzo, 0.37kW mpaka 4kW, chifukwa cholephera kulowa.
Mphamvu yamagetsi: Single-gawo, ngati 200-240V.
Mphamvu ya Output: Magawo atatu, mwachitsanzo, 200-240V, yamagalimoto.
Zoyambira Zofewa
Zomwe Iwo Ali: Zoyambira Zofewa zimakweza ma voliyumu pang'onopang'ono pakuyambitsa kwa injini kuti zichepetse mawotchi apano, zimachepetsa kupsinjika kwamakina ndi magetsi, kumatalikitsa moyo wamagalimoto. Mapulogalamu: Oyenera pamapampu, ma compressor, ndi ma conveyor pomwe zimayambira mwadzidzidzi zimayambitsa zovuta
Adavoteledwa: Imafanana ndi injini yapano, mwachitsanzo, 10A mpaka 1000A.
Mphamvu ya Voltage: Imagwirizana ndi kupezeka, mwachitsanzo, 200-690V.
Control Circuit Voltage: Magetsi oyambitsa, mwachitsanzo, 24V DC, 110V AC.
Ma Braking Resistors
Zomwe Iwo Ali: Zophatikizidwa ndi ma VFD, Ma Braking Resistors amataya mphamvu zochulukirapo panthawi yothamangitsidwa mwachangu, amawonetsetsa kuyimitsidwa kotetezeka, kolamuliridwa poletsa kuchulukitsidwa kwagalimoto. Ntchito: Zofunikira pama elevator, ma cranes, ndi katundu wozama kwambiri wofunikira kuyimitsidwa mwachangu
Kukaniza Mtengo: Mu ohms, mwachitsanzo, 10Ω mpaka 100Ω, kuti mufanane ndi VFD.
Mulingo wa Mphamvu: Mu ma watts, mwachitsanzo, 500W mpaka 5000W, kuthana ndi kutaya mphamvu.
