VFD uye nyoro inotangisa inogona kuita mabasa akafanana kana zvasvika pakurerekera kumusoro kana kudzika mota.Shanduko huru pakati pezviviri izvi ndeyekuti VFD inokwanisa kusiyanisa kumhanya kwemota kunyangwe nyoro inotangisa inongodzora matangiro uye kumira kwemota iyoyo.
Kana watarisana nechikumbiro, kukosha, uye saizi zviri mururemekedzo rweanotangisa akapfava.VFD ndiyo sarudzo inoshanda zvakanyanya kana kukurumidza kudzora kwakakosha.Izvo zvakanaka kuti uwane yakavimbika yakapfava yekutanga mugadziri wekutenga yakanakisa mhando chigadzirwa chekushandisa kwako.Pazasi, ini ndichagovera misiyano pakati peVFD uye yakapfava yekutanga iyo ichakubatsira iwe kuona kuti ndechipi chishandiso chaungade.
Chii chinonzi VFD?
VFD kazhinji inomirira kuchinjika frequency drive iyo inowanzo shandiswa kumhanyisa mota yeAC pakumhanya kwakasiyana.Ivo vanonyanya kushanda nekugadzirisa frequency yemota kugadzirisa ramps.
Chii chinonzi Soft Starter?
Iwo marongero akafanana mukuti ivo rheostat kutanga uye kumira kwemamota ekugadzira asi vane maitiro akasiyana.
Iwo anowanzo shandiswa mumashandisirwo uko kune hombe kukwira kweazvino kunogona kukuvadza mota nepo VFD inodzora uye inogona kusiyanisa kukurumidza kwemota.
- Kushanda Kwemukati kweSoft Starter
Iyo 3-chikamu chakapfava stater inoshandisa matanhatu thyristors kana silicon-inodzorwa rectifiers, yakatarisana mune anti-parallel formation kuti itambise mota dzemagetsi zviri nyore.
A thyristor inoumbwa nezvikamu zvitatu:
- Logic gedhi
- Cathode
- Anode
Kana kupuruzira kwemukati kuchishandiswa kugedhi, inoregedza ikozvino kudonha kubva kune anode kuenda kune cathode iyo inozotungamira ikozvino kunze kune mota.
Kana iwo emukati mapurusi akasapfeka kugedhi, iyo SCRs (Silicon Inodzorwa Rectifier) iri kunze kwenyika uye saka vanoisa iyo yazvino kumota.
Aya ari mukati ma pulses anopinza magetsi akaiswa kune mota inodzikisira pasi ichidurura ikozvino.Iwo mapurusi anorehwa akavakirwa pane yakatsetseka nguva saka yazvino ichaiswa zvishoma nezvishoma kune mota.Iyo mota inozotanga kumusoro pane yakanaka flat ikozvino uye yepamusoro-soro kunze kune yakafanotemerwa yakanyanya kumhanya.
Iyo mota inogara pakukurumidza ikoko kudzamara wamisa mota uko iyo yakapfava inotanga inotsvedza pasi mota nenzira yakafanana neyekusimudzira kumusoro.
- Kushanda Kwemukati kweVFD
VFD ine zvikamu zvitatu, zvinosanganisira:
- Rectifier
- Sefa
- Inverter
Iyo inogadziridza inoita senge diode, inowana iyo yemukati AC voltage uye inoishandura kuita DC voltage.Uye iyo sefa inoshandisa capacitors kuchenesa iyo DC voltage ichiita kuti ive simba rekusvika rakapfava.
Chekupedzisira, inverter inoshandisa transistors kushandura iyo DC voltage uye inotungamira mota kune frequency muHertz.Iyi frequency inotanga mota kune chaiyo RPM.Iwe unogona kuseta iyo gradient kumusoro uye downtimes zvakangofanana mune yakapfava yekutanga.
VFD kana Soft Starter?Ndeipi Yaunofanira Kusarudza?
Kubva pane zvawabva kutaura;unogona kuona kuti VFD inowanzova yakapfava inotangisa ine kumhanya mhanya.Saka iwe unosiyanisa sei kuti ndeipi mudziyo unodiwa pakushandisa kwako?
Sarudzo yemudziyo waunosarudza inodzika kune yakawanda sei rheostat application yako inosanganisira.Pane zvimwe zvinhu zvaunofanira kuita nemaune muchisarudzo chako.
- Speed Kudzora: Kana application yako ichida hombe inrush yeazvino asi isingade kumhanya kudzora, saka yakapfava yekutanga ndiyo yepamusoro sarudzo.Kana kumhanya rheostat ichidikanwa, saka VFD yakakosha.
- Mutengo: Mutengo unogona kuve chinhu chinotsanangura mune yakawanda-chaiyo-yepasirese application.Zvichakadaro, nyoro yekutanga ine isingawanzo kudzora maficha, kukosha kwakaderera pane VFD.
- Saizi: Chekupedzisira, kana saizi yechishandiso chako iri kutsanangura pesvedzero, zvinyoro zvekutanga zvinowanzo diki pane mazhinji eVFDs.Ikozvino, ngatitarisei pane mamwe-chaiwo epasirese kutumira kuti akubatsire kuona shanduko pakati peVFD neyakapfava yekutanga.
Ruzivo rwadudzwa pamusoro ruchakubatsira mukusiyanisa mutsauko uripo pakati peVFD neyekutanga yakapfava.Unogona kuwana imwe yeakanakisa akanakisa ekutanga anogadzira mota muChina, kana kumwewo, kutenga zvigadzirwa zvemhando yepamusoro nemitengo inonzwisisika.
