INVT variable frequency VFD mndandanda wazinthu zimakwaniritsa zosowa zamapulogalamu

1. Gawo la GD350-19
Ntchito: Zapangidwira ma cranes, omwe amagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana monga madoko, mafakitale, malo omanga ndi migodi.
Zaukadaulo:
Kuchita bwino kwambiri komanso kupulumutsa mphamvu: Chepetsani kugwiritsa ntchito mphamvu powongolera liwiro ndi mphamvu yagalimoto.
Torque yamphamvu yotsika pafupipafupi: 200% ya makokedwe ovotera amatha kutulutsa pa 0Hz mumayendedwe owongolera vekitala (FVC); 150% ya torque yovotera imatha kutulutsa pa 0.5Hz mumayendedwe owongolera voteji.
Kusinthasintha kwabwino kwa katundu: The optimized control algorithm imathandizira kuti torque yotulutsa ikhale yosinthika molingana ndi momwe zimakhalira kuti zitonthozedwe bwino ngati palibe katundu kapena katundu.
Ntchito zapadera: Imathandizira kuwongolera kwamakono kwa ma cranes a tower, conical rotor motor control, ma braking logic yapadera, chitetezo choletsa kuyenda, anti-sway chitetezo, chitetezo chazingwe chotayirira ndi zero servo, ndi zina zambiri.
Chitetezo cha Chitetezo: Ili ndi ntchito zoteteza chitetezo chambiri monga chitetezo chopitilira muyeso, chitetezo chamagetsi, chitetezo chamagetsi ndi chitetezo cha gawo, ndi zina zambiri, kuonetsetsa kuti galimotoyo ikugwira ntchito mokhazikika pamalo ogwirira ntchito ovuta.
2. GD200A Series VFD
Kugwiritsa ntchito: Oyenera zida zosiyanasiyana zamagetsi zamagetsi, monga zida zolemetsa, mafani, mapampu, ndi zina zambiri.
Zaukadaulo:
Kulemera kwa katundu: Zapangidwira ntchito zolemetsa, zomwe zimatha kupirira kusinthasintha kwakukulu ndi kugwedezeka.
Kuwongolera molondola: Kutha kuwongolera molondola liwiro la mota ndi torque, kumakwaniritsa zofunikira zowongolera pansi pazikhalidwe zosiyanasiyana zogwirira ntchito.
Zosavuta kukonza: Ndi mapangidwe amtundu, kulumikizana pakati pa gawo lililonse ndikosavuta komanso komveka bwino, kosavuta kukonza ndikusintha.
Chitetezo chambiri: Amapereka njira zingapo zotetezera kuti zitsimikizire kugwira ntchito mokhazikika kwa mota m'malo osiyanasiyana ogwira ntchito.
3. GD10 Series VFD
Ntchito: Yoyenera zida zazing'ono ndi zida zapakhomo, monga ma mini motors, ma air conditioners osiyanasiyana, etc.
Zaukadaulo:
Compact Design: Kukula kwakung'ono, kapangidwe kameneka, kosavuta kukhazikitsa ndikuphatikiza.
Kupulumutsa mphamvu moyenera: Kuchita bwino kwambiri komanso kupulumutsa mphamvu kumatheka mwa kuwongolera molondola liwiro ndi mphamvu yagalimoto.
Kusavuta kugwiritsa ntchito: Kugwira ntchito kosavuta, kosavuta kukonza ndi kukonza.
Chitetezo cha ntchito: Amapereka njira zodzitetezera kuti zitsimikizire kuti mota imagwira ntchito moyenera.
IV. Mitundu ina ya VFD
Kuphatikiza pa mndandanda womwe uli pamwambapa, INVT yakhazikitsanso mitundu ina yamitundu yosiyanasiyana ya zinthu za VFD, monga mndandanda wa GD20, mndandanda wa ES840, ndi zina zambiri. Mankhwalawa alinso ndi mawonekedwe amphamvu kwambiri komanso kupulumutsa mphamvu, kuwongolera molondola, kukonza kosavuta ndi chitetezo chachitetezo, ndipo ndi oyenera mitundu yosiyanasiyana ya ma mota a AC ndi machitidwe owongolera.
INVT VFD mndandanda wazinthu: Kutsogolera mutu watsopano mu Industrial drive

Zogulitsa za INVT VFD ndi m'badwo watsopano wamagalimoto osinthika pafupipafupi opangidwa mosamala ndi INVT kutengera zaka zopitilira khumi zomwe zakhala zikuchitikira pakampani ya crane ndiukadaulo wapamwamba wowongolera. Zogulitsazi zimaphatikiza ntchito zowongolera zapadera zonyamula katundu ndi ntchito zotetezeka za torque off (STO), ndipo zitha kugwiritsidwa ntchito kwambiri pama crane osiyanasiyana m'magawo osiyanasiyana monga madoko, mafakitale, malo omanga ndi migodi, kuwonetsa kuwongolera bwino, ntchito zoteteza chitetezo chokwanira komanso kuthekera kosinthika kokulirapo.

Mphamvu zosiyanasiyana za mankhwala INVT VFD mndandanda ndi lonse, kuphimba 1.5 ~ 500kW wa AC 380V (-15%) ~ 440V (+10%) ndi 22 ~ 630kW wa AC 520V (-15%) ~ 690V (+ 10%). Izi zimawathandiza kuti akwaniritse ntchito zamafakitale zamitundu yosiyanasiyana komanso zosowa.

Pankhani ya magwiridwe antchito, mndandanda wa INVT VFD uli ndi zinthu zingapo zodziwika bwino. Choyamba, ali ndi mphamvu yotulutsa torque yotsika kwambiri, yomwe imatha kupereka torque ya 0Hz/200% (yovotera torque) mumayendedwe owongolera vekitala (FVC), ndi 0.5Hz/150% (ma torque ovotera) mumayendedwe owongolera voteji. Izi zimathandiza kuti crane igwire ntchito bwino komanso moyenera pansi pa zinthu zosiyanasiyana zolemetsa.

Chachiwiri, mndandanda wa INVT VFD uli ndi kusinthika kwabwino kwambiri. Kupyolera mu ma aligorivimu owongolera, amatha kusintha ma torque malinga ndi momwe zinthu ziliri, kuwonetsetsa kuti crane imatha kupereka chitonthozo chabwino ikatsitsidwa kapena kutsitsa.

Kuphatikiza apo, mndandanda wa INVT VFD ulinso ndi ntchito zosiyanasiyana zapadera zamapulogalamu a crane. Mwachitsanzo, amathandizira kuwongolera kwaposachedwa kwa ma cranes a tower, amatha kuyimitsa mabuleki am'mbuyo mwachangu, kupita patsogolo mwachangu komanso kusinthana m'mbuyo ndikusintha mothamanga kwambiri. Nthawi yomweyo, amathanso kusintha maginito molingana ndi mawonekedwe a ma conical rotor motors, kukwanitsa kumasula mabuleki mwachangu ndi kuwongolera kotseka, kumathandizira masitepe ndikuwonetsetsa chitetezo cha zida.

Pankhani ya chitetezo, mndandanda wa INVT VFD umachitanso bwino. Amaphatikiza ntchito yotsimikizira ma torque kuti awonetsetse kuti ntchito yotetezeka komanso yosasunthika ma torque atakhazikitsidwa. Nthawi yomweyo, amathandizanso kugwiritsa ntchito kusankha koyambira komanso kusankha ma brake kutsogolo ndikusintha kusinthana kuti akwaniritse zosowa zosiyanasiyana zoyambira. Kuphatikiza apo, mndandanda wa INVT VFD ulinso ndi ntchito monga chitetezo cham'mwamba ndi chotsikirapo komanso chitetezo chapamwamba komanso chotsika, chomwe chingathe kuchepetsa crane kuti igwire ntchito mosiyanasiyana, kuonetsetsa chitetezo ndikukhathamiritsa njira yotsekera kuti zithandizire bwino zida.

Ndikoyenera kutchula kuti mndandanda wa INVT VFD ulinso ndi chitetezo chotsutsa. Amagwiritsa ntchito algorithm yopanda mphamvu yotsutsa-sway control, yomwe imatha kusinthidwa mosavuta ndikusinthidwa kuti igwirizane ndi zosowa zotsutsana ndi zowongolera zama cranes osiyanasiyana. Kuphatikiza apo, amakhalanso ndi ntchito yoteteza zingwe zotayirira kuti apewe kukweza kwambiri, kulephera kwachangu komanso ngozi zachitetezo pamalo otayirira zingwe.

Pankhani yopulumutsa mphamvu komanso kuteteza chilengedwe, mndandanda wa INVT VFD umachitanso bwino. Amatha kuchepetsa kugwiritsa ntchito mphamvu mwa kuwongolera ndendende liwiro ndi mphamvu yagalimoto. Poyerekeza ndi zoyendetsa zamagalimoto azikhalidwe, mndandanda wa INVT VFD ungathe kusintha liwiro ndi mphamvu yagalimotoyo potengera ntchito zosiyanasiyana, potero kukwaniritsa chiwongolero champhamvu champhamvu. Panthawi imodzimodziyo, amakhalanso ndi phokoso lochepa komanso kugwedezeka, ndipo alibe mphamvu zambiri pa chilengedwe.

Mwambiri, zogulitsa za INVT VFD zakhala zikugwira ntchito kwambiri pamagalimoto amakampani ndi magwiridwe antchito ake, magawo ambiri ogwiritsira ntchito komanso kupulumutsa mphamvu komanso kuteteza chilengedwe. Kaya mumakampani a crane kapena m'mafakitale ena, zida za INVT VFD zitha kupatsa ogwiritsa ntchito njira zoyendetsera bwino, zodalirika komanso zotetezeka. Ndi kupita patsogolo kosalekeza kwaukadaulo komanso kukulirakulira kosalekeza kwa magawo ogwiritsira ntchito, zinthu za INVT VFD zitenga gawo lofunikira kwambiri pachitukuko chamtsogolo cha mafakitale.
