Hoʻokō nā huahana ʻo INVT variable frequency VFD i nā pono o nā noi

1. GD350-19 moʻo VFD
Noi: Hoʻolālā ʻia no nā cranes, hoʻohana nui ʻia i nā ʻano like ʻole e like me nā awa, nā hale hana, nā kahua kūkulu a me nā mining.
Nā hiʻohiʻona ʻenehana:
Kiʻekiʻe kiʻekiʻe a me ka ikehu malama: E hoemi i ka ikehu ma ka hoomalu pono ana i ka mama a me ka mana o ke kaa.
ʻO ka torque haʻahaʻa haʻahaʻa ikaika: Hiki ke hoʻopuka ʻia ka 200% o ka torque i koho ʻia ma 0Hz i ke ʻano mana vector control (FVC); Hiki ke hoʻopuka ʻia ka 150% o ka torque i koho ʻia ma 0.5Hz i ke ʻano mana vector control space.
Hiki ke hoʻololi i ka ukana maikaʻi: Hiki i ka algorithm control optimized ke hoʻololi kūpono i ka torque hoʻopuka e like me nā kūlana ukana e loaʻa ai ka hōʻoluʻolu maikaʻi loa inā ʻaʻohe ukana a ukana.
Nā hana kūikawā: Kākoʻo i ka mana slewing eddy i kēia manawa o nā tower cranes, conical rotor motor control, special braking logic, travel limit protection, anti-sway protection, loose rope protection and zero servo, etc.
Palekana palekana: Loaʻa iā ia nā hana palekana palekana e like me ka overcurrent protection, overvoltage protection, undervoltage protection and phase protection, etc., e hōʻoia i ka hana paʻa o ka kaʻa i kahi ʻano hana paʻakikī.
2. GD200A Series VFD
Hoʻohana: He kūpono no nā mea hana ʻenehana ʻenehana, e like me nā mea hana kaumaha, nā mea pā, nā pamu, a pēlā aku.
Nā hiʻohiʻona ʻenehana:
Kaha kaumaha: Hoʻolālā kūikawā ʻia no nā noi kaumaha, hiki ke kū i ka loli nui a me nā haʻalulu.
Ka mana pololei: Me ka hiki ke hoʻomalu pono i ka wikiwiki a me ka torque, hoʻokō ia i nā koi mana ma lalo o nā kūlana hana paʻakikī.
Maʻalahi e mālama: Me ka hoʻolālā modular, maʻalahi a maʻalahi ka pilina ma waena o kēlā me kēia ʻāpana, maʻalahi e mālama a hoʻololi.
Nā pale he nui: Hāʻawi i nā mīkini pale he nui e hōʻoia i ka hana paʻa o ka kaʻa ma nā wahi hana like ʻole.
3. GD10 Series VFD
Hoʻohana: He kūpono no nā mea liʻiliʻi a me nā mea pono hale, e like me nā mīkini mini, nā ea ea maʻamau, etc.
Nā hiʻohiʻona ʻenehana:
Hoʻolālā paʻakikī: ʻO ka liʻiliʻi liʻiliʻi, ka hana paʻa, maʻalahi e hoʻokomo a hoʻohui.
Hoʻopakele ikehu kūpono: Loaʻa ka hana kiʻekiʻe a me ka mālama ʻana i ka ikehu ma o ka hoʻomalu pono ʻana i ka wikiwiki a me ka mana o ke kaʻa.
ʻO ka maʻalahi o ka hoʻohana: hana maʻalahi, maʻalahi e hoʻonohonoho a me ka debug.
Hana pale: Hāʻawi i nā mīkini pale kumu e hōʻoia i ka holo ʻana o ka kaʻa i loko o ka pae hana maʻamau.
IV. Nā moʻo ʻē aʻe o VFD
Ma waho aʻe o ka papahana i luna, ua hoʻokumu pūʻo INVT i nāʻano likeʻole o nā huahana VFD, e like me ka GD20 series, ES840 series, a me nā mea'ē aʻe.
Nā huahana INVT VFD series: Ke alakaʻi nei i kahi mokuna hou i ka ʻoihana ʻoihana

ʻO nā huahana INVT VFD series he hanauna hou o ka hoʻololi pinepine ʻana i hoʻomohala ʻia e INVT e pili ana i ʻoi aku ma mua o ʻumi mau makahiki o ka ʻike i ka ʻoihana crane a me ka ʻenehana hoʻokele holomua. Hoʻohui kēia mau huahana i ka waiwai o nā hana mana kūikawā no ka ʻoihana hāpai a me nā hana palekana torque off (STO), a hiki ke hoʻohana nui ʻia i nā cranes like ʻole i nā kahua like ʻole e like me nā awa, nā hale hana, nā kahua kūkulu a me nā mining, e hōʻike ana i ka hana hoʻomalu maikaʻi, nā hana palekana palekana piha a me nā hiki ke hoʻonui.

He ākea ka mana o nā huahana INVT VFD series, e uhi ana i ka 1.5~500kW o AC 380V (-15%)~440V (+10%) a me 22~630kW o AC 520V (-15%)~690V (+10%). Hiki iā lākou ke hoʻokō i nā noi ʻoihana o nā ʻano nui a me nā pono.

I ka ʻōlelo o ka hana, ʻo ka INVT VFD series he mau hiʻohiʻona kaulana. ʻO ka mea mua, loaʻa iā lākou ka mana hoʻokuʻu haʻahaʻa haʻahaʻa haʻahaʻa, hiki ke hāʻawi i ka torque 0Hz/200% (rated torque) i ke ʻano mana vector manaʻo (FVC), a me 0.5Hz/150% (rated torque) i ke ʻano hoʻokele uila uila. ʻO kēia ka mea e hiki ai i ka crane ke hana me ka maʻalahi a me ka maikaʻi ma lalo o nā kūlana ukana like ʻole.

ʻO ka lua, ʻo ka moʻo INVT VFD he hiki ke hoʻololi i ka ukana. Ma o ka optimized control algorithms, hiki iā lākou ke hoʻololi i ka torque output e like me nā kūlana ukana, e hōʻoia ana e hiki i ka crane ke hāʻawi i ka hōʻoluʻolu maikaʻi loa i ka wā i hoʻoiho ʻia a hoʻouka ʻia.

Eia kekahi, ʻo ka INVT VFD series kekahi mau hana kūikawā no nā noi crane. No ka laʻana, kākoʻo lākou i ka mana slewing eddy i kēia manawa-free o nā tower cranes, hiki ke hoʻōki koke i ka hoʻihoʻi ʻana i ka braking, hoʻokō wikiwiki i mua a hoʻohuli i ka hoʻololi ʻana a me ka hoʻonohonoho hoʻonohonoho haʻahaʻa haʻahaʻa. I ka manawa like, hiki iā lākou ke hoʻoponopono i ka flux magnetic e like me nā hiʻohiʻona o nā kaʻa rotor conical, hoʻokō i ka hoʻokuʻu wikiwiki a me ka hoʻopaʻa ʻana i ka mana, hoʻomaʻamaʻa i nā ʻanuʻu komisina a hōʻoia i ka palekana o nā lako.

Ma ke ʻano o ka palekana, hana maikaʻi ka pūʻulu INVT VFD. Hoʻohui lākou i kahi hana hōʻoia torque e hōʻoia i ka hana palekana a paheʻe ʻole ma hope o ka hoʻokumu ʻia ʻana o ka torque. I ka manawa like, kākoʻo pū lākou i ka hoʻohana ʻana i ke koho kuhikuhi hoʻomaka a me ke koho ʻana i ka hoʻololi ʻana i mua a me ka hoʻohuli ʻana e hoʻokō i nā pono hoʻomaka. Eia kekahi, he mau hana ko ka INVT VFD series e like me ka pale ʻana o ka palena kiʻekiʻe a me lalo a me ka pale deceleration palena kiʻekiʻe a me lalo, hiki ke kaupalena i ka hana o ka crane i loko o kahi kikoʻī, e hōʻoia i ka palekana a hoʻopaʻa i ke ala pani e hoʻomaikaʻi ai i ka pono o nā lako.

He mea kūpono ke haʻi ʻana i ka pūʻulu INVT VFD pū kekahi i ka pale anti-sway. Hoʻohana lākou i kahi algorithm anti-sway control sensorless, hiki ke maʻalahi i ka debugged a maʻalahi hoʻi i nā pono anti-sway control o nā cranes like ʻole. Eia kekahi, loaʻa iā lākou kahi hana pale kaula e pale aku ai i ka hoʻokiʻekiʻe kiʻekiʻe, hāʻule ka wikiwiki a me nā pōʻino palekana ma kahi kūlana kaula.

Ma ke ʻano o ka mālama ʻana i ka ikehu a me ka pale ʻana i ke kaiapuni, hana maikaʻi ka pūʻulu INVT VFD. Hiki iā lākou ke hōʻemi i ka hoʻohana ʻana i ka ikehu ma ka hoʻomalu pono ʻana i ka wikiwiki a me ka mana o ke kaʻa. Ke hoʻohālikelike ʻia me nā kaʻa kaʻa kuʻuna, hiki i ka moʻo INVT VFD ke hoʻololi i ka wikiwiki a me ka mana o ka kaʻa ma lalo o nā ʻano hana like ʻole, a laila e loaʻa ai ka lākiō ʻoi aku ka ikaika o ka ikehu. I ka manawa like, liʻiliʻi ka walaʻau a me ka haʻalulu, a ʻoi aku ka liʻiliʻi o ka hopena i ke kaiapuni.

Ma ka laulā, ua lilo nā huahana INVT VFD i mea koʻikoʻi i ke kahua o ka hana ʻenehana me kā lākou hana maikaʻi loa, nā kahua noi ākea a me nā hiʻohiʻona hoʻōla ikaika a me nā ʻano palekana kūlohelohe. Inā i loko o ka ʻoihana crane a i ʻole nā ​​​​ʻoihana ʻoihana ʻē aʻe, hiki i nā huahana INVT VFD series ke hāʻawi i nā mea hoʻohana i nā hopena hoʻokele kūpono, hilinaʻi a palekana. Me ka hoʻomau mau ʻana o ka ʻenehana a me ka hoʻonui mau ʻana o nā kahua noi, ʻoiaʻiʻo e pāʻani nā huahana INVT VFD series i kahi kuleana nui i ka hoʻomohala ʻana i ka ʻoihana e hiki mai ana.
