I-Precision Motor Control enama-VFD Ekhwalithi Ephezulu avela ku-Global Brands
Iyini i-VFD?
I-Variable Frequency Drive (VFD) iyithuluzi elibalulekile lokulawula izimboni elisetshenziselwa ukulawula isivinini kanye ne-torque yamamotho e-AC ngokulungisa imvamisa namandla kagesi. Ama-VFD athuthukisa ukusebenza kahle kwamandla, anciphisa ukucindezelwa kwemishini, futhi athuthukise ukulawulwa kwenqubo ezinhlelweni ezihlukahlukene, okuhlanganisa amaphampu, amafeni, ama-conveyors, namasistimu e-HVAC.
Sinikeza ama-VFD ayiqiniso, asezingeni eliphezulu kusukela ezinkampanini ezihamba phambili zomhlaba jikelele ezifana Siemens, Schneider, Yaskawa, futhi I-ABB, ukuqinisekisa ukwethembeka, ukusebenza, futhi ukuqina kwesikhathi eside ngezidingo zakho zezimboni. Kungakhathaliseki ukuthi okuzenzakalelayo, ukonga amandla, noma ukulawulwa kwezimoto okunembile, imikhiqizo yethu ihlangabezana ne amazinga aphezulu embonini.
Izingxenye Eziyinhloko Zohlelo lwe-VFD
Amadrayivu e-AC
Lokho Abayikho: Amadrayivu e-AC, ajwayele ukubizwa ngokuthi ama-Variable Frequency Drives (VFDs), lungisa isivinini kanye ne-torque yamamotho e-AC ngokushintsha imvamisa namandla kagesi, ahlinzeka ngokulawula isivinini okunembile, onge amandla, futhi anciphise ukugqokwa kwezimoto ngokusebenza okushelelayo. Izinhlelo zokusebenza: Ilungele amaphampu, amafeni, amaconveyor, namasistimu e-HVAC adinga isivinini esiguquguqukayo
Amandla Alinganiselwe: Ifanisa isilinganiso samandla emoto.
I-Voltage Yokufaka: Iqondana ne-voltage yokuhlinzeka.
Izigaba zokufaka: 1-isigaba noma 3-isigaba, ngokusekelwe ohlelweni.
Ama-DC Drives
Lokho Eziyikho: Amadrayivu e-DC alawula isivinini semoto ye-DC kanye ne-torque ngokushintsha amandla kagesi anikezwe injini, aletha ukuguqulwa okuqondile, okunembile kwejubane lemisebenzi ethile. Izinhlelo zokusebenza: Isetshenziswa kumasistimu amadala, amakheshi, amakhreni, nemishini edinga itorque eqinile.
Okukhiphayo Okukaliwe kwamanje: Ubuningi bamanje (isb., 10A ukuya ku-1000A) idrayivu inganikezela.
I-Voltage elinganiselwe yokuphumayo: I-voltage ye-DC (isb., 180V, 500V) yenjini.
I-Voltage Yokufaka: I-voltage yokunikezwa kwe-AC (isb., 230V, 400V).
Izigaba zokufaka: Okokufaka kwesigaba esisodwa noma oku-3, kuye ngedrayivu.
KANYE VSD
Lokho Eziyikho: Ama-AC VSD ngelinye igama lama-AC Drives noma ama-VFD, agxile ekhonweni lawo lokushintsha isivinini semoto, akhulisa ukusebenza kwemoto nokusebenzisa amandla ngokugwema ukusebenza kwesivinini esingaguquki. Izicelo: Zivamile kumasistimu wokuzenzakalela, ukukhiqiza, kanye namasistimu awonga amandla
Amandla Alinganiselwe: Ifanisa isilinganiso samandla emoto.
I-Voltage Yokufaka: Iqondana ne-voltage yokuhlinzeka.
Izigaba zokufaka: 1-isigaba noma 3-isigaba, ngokusekelwe ohlelweni.
Amadrayivu esigaba esisodwa
Lokho Ayikho: Lawa ma-VFD enzelwe amamotho e-AC esigaba esisodwa, avame ukutholakala kumasethingi amancane, aletha ukulawulwa kwesivinini kumamotho esigaba esisodwa, athuthukisa ukusebenza kahle ezinhlelweni ezihlangene. Izicelo: Ilungele abalandeli bezindawo zokuhlala, ama-blower, namaphampu amancane
Amandla Alinganiselwe: Ivamise ukuba ngaphansi, isb, 0.37kW kuya ku-4kW, ngenxa yemikhawulo yokufaka.
I-Voltage Yokufaka: Isigaba esisodwa, njenge-200-240V.
I-Voltage Yokuphumayo: Izigaba ezintathu, isb, 200-240V, injini.
Iziqalisi Ezithambile
Lokho Eziyikho: Iziqalisi Ezithambile zenyusa i-voltage kancane kancane ngesikhathi sokuqalisa ukuze zikhawulele ukukhuphuka kwamanje, zinciphisa ingcindezi yemishini nekagesi, zandise impilo yemoto. Izinhlelo zokusebenza: Ilungele amaphampu, ama-compressor, nama-conveyor lapho ukuqala kungazelelwe kubangela izinkinga
Ikalwe okwamanje: Ifanisa amandla amanje enjini, isb, 10A kuya ku-1000A.
I-Voltage elinganiselwe: Iqondanisa nokunikezwayo, isb, 200-690V.
Lawula i-Voltage Circuit: Amandla kagesi okusebenza, isb, 24V DC, 110V AC.
Ama-Braking Resistors
Lokho Eziyikho: Kubhangqiwe nama-VFD, Ama-Braking Resistors achitha amandla amaningi ngesikhathi sokuncipha kwemoto ngokushesha, aqinisekisa ukuma okuphephile, okulawulwayo ngokuvimbela ukugcwala kwe-drive overvoltage. Izinhlelo zokusebenza: Ibalulekile kumakheshi, amakhreni, nemithwalo ye-inertia ephezulu edinga ukuma okusheshayo
Inani Lokumelana: Ngo-ohms, isb, 10Ω ukuya ku-100Ω, ukuze kufane ne-VFD.
Isilinganiso samandla: Ngama-watts, isb, 500W kuya ku-5000W, ukuphatha ukushabalaliswa kwamandla.
