No ke aha e hiki ʻole ai i kahi kaʻa induction ke hana me ka wikiwiki synchronous?

Introduction

Loaʻa nā ʻenekini induction i nā noi ʻoihana ma muli o kā lākou kūkulu paʻa, hilinaʻi, a me ka pono. Eia nō naʻe, ʻo kekahi o nā hiʻohiʻona kumu o kahi kaʻa induction ʻaʻole ia e hana ma ka wikiwiki synchronous. Ke hāpai nei kēia ʻano ʻokoʻa i nā nīnau e pili ana i kāna hoʻolālā ʻana a me kāna hana ʻana, ʻoi aku hoʻi ke hoʻohālikelike ʻia me nā kaʻa synchronous. Ma kēia moʻomanaʻo, e ʻimi mākou i nā mea paʻakikī o nā kaʻa induction, e kālele ana kiʻekiʻe voltage induction motors, a e ʻimi i nā kumu ma hope o ko lākou hiki ʻole ke hōʻea i ka wikiwiki synchronous. E kūkākūkā pū mākou i nā ʻokoʻa ma waena o nā ʻenekini synchronous a me induction, nā mea maikaʻi o nā kaʻa induction, ka manaʻo o ka paheʻe, a me ke kuleana o nā māla magnetic i kā lākou hana.

Ka hoʻomaopopo ʻana i nā Motors Synchronous a me Induction Motors

Nā Motors Synchronous: ʻO ka pololei i kona maikaʻi loa

Hoʻolālā ʻia nā motika synchronous e hana i ka wikiwiki mau, i ʻike ʻia ʻo ka wikiwiki synchronous, i hoʻoholo ʻia e ke alapine o ka hāʻawi ʻana i kēia manawa a me ka helu o nā pou i loko o ke kaʻa. Ke hoʻomau mau nei kēia wikiwiki me ka nānā ʻole i ka ukana, e hana ana i nā kaʻa synchronous i kūpono no nā noi e koi ana i ka mana wikiwiki a paʻa. Hiki ke helu ʻia ka wikiwiki synchronous (Ns) me ka hoʻohana ʻana i ke ʻano:

Ns=120×f/P​

kahi f ka alapine (frequency) o ke au hoolako ma Hertz a o P ka heluna o na pou.

I nā kaʻa kaʻa synchronous, ua laka ʻia ka rotor me ke kahua magnetic o ka stator. ʻO kēia laka e hōʻoia i ka holo ʻana o ka rotor i ka wikiwiki like me ke kahua magnetic o ka stator, no laila ka huaʻōlelo 'synchronous.' Hoʻohana nui ʻia kēia mau kaʻa i nā noi e like me nā uaki, nā manawa, a me nā mea hana ʻē aʻe kahi e pono ai ka mālama manawa kūpono.

Nā Motors Induction: Mana a me ka maʻalahi

ʻO ka hoʻohālikelike ʻana, ʻo nā motika induction, i ʻike ʻia ʻo asynchronous motors, e hana ma ke kumu o ka electromagnetic induction. ʻO ka rotor i a kiʻekiʻe voltage induction motor ʻaʻole pili uila i ka lako. Akā, ua hoʻoulu ʻia e ke kahua magnetic rotating i hana ʻia e ka stator. Hoʻokumu ʻia kēia manawa i loko o ka rotor i kahi māla magnetic e pili ana me ke kahua o ka stator, e hoʻohuli ai ka rotor.

ʻO ka ʻokoʻa koʻikoʻi ma waena o ka synchronous a me ka induction motors aia i kā lākou wikiwiki hana. ʻAʻole e like me nā motika synchronous, ʻaʻole hiki ke holo i nā motor induction i ka wikiwiki synchronous. Akā, hana mau lākou i ka māmā liʻiliʻi ma mua o ka wikiwiki synchronous. ʻO kēia ʻokoʻa i ka wikiwiki he mea nui ia no ka induction motor e hana i ka torque a hana pono.

Nā Pōmaikaʻi o nā Motors Induction Ma mua o nā Motors Synchronous

Hāʻawi nā ʻenekini induction i nā mea maikaʻi ma mua o nā kaʻa synchronous, e hoʻolilo iā lākou i koho kaulana i nā noi ʻoihana like ʻole. ʻO kekahi o kēia mau mea maikaʻi:

ʻO ka maʻalahi a me ka lōʻihi: He hana maʻalahi a paʻakikī nā mīkini induction, kahi e paʻa ai a maʻalahi hoʻi e mālama. ʻAʻole lākou e koi i nā pulupulu a i ʻole nā ​​apo paʻa, e hōʻemi ana i ka lole a me ka waimaka.

Uku-kumu: Ma muli o kā lākou hoʻolālā maʻalahi a me ka hoʻohana ākea ʻana, ʻoi aku ka maʻalahi o nā mīkini induction ma mua o nā kaʻa synchronous. Hoʻonui kēia kumukūʻai i ka kūʻai mua ʻana a me ka mālama ʻana.

Hana Pono: Ua ʻike ʻia nā motika induction no kā lākou hana hilinaʻi i nā kūlana kaiapuni. Hiki iā lākou ke pale i nā kūlana koʻikoʻi, e like me ka lepo, ka makū, a me nā ʻano wela, me ka ʻole o ka hoʻohaʻahaʻa hana.

Hiki ke hoʻomaka ponoʻī: ʻAʻole like me nā kaʻa synchronous, e koi ana i nā ʻano hana hou e hoʻomaka ai, hoʻomaka pono nā motika induction. Hoʻomaʻamaʻa kēia hiʻohiʻona i kā lākou hana a hoʻemi i ka pono o nā mea ʻē aʻe.

Laulā o nā noi: Kiʻekiʻe voltage induction motors kūpono no ka laulā o nā noi, mai nā mea hana hale liʻiliʻi i nā mīkini ʻoihana nui. ʻO kā lākou versatility a me ka paʻa i kūpono no nā hoʻohana like ʻole.

Paheʻe i loko o Induction Motors: He mea e pono ai

He manaʻo koʻikoʻi ka Slip i ka hoʻomaopopo ʻana i ke kumu ʻaʻole hiki i nā mīkini induction ke hiki i ka wikiwiki synchronous. Ua wehewehe ʻia ka Slip e like me ka ʻokoʻa ma waena o ka wikiwiki synchronous a me ka wikiwiki rotor maoli, i hōʻike ʻia ma ke ʻano he pākēneka o ka wikiwiki synchronous. Ma ka makemakika, hāʻawi ʻia ka slip (S) e:

S=(Ns−Nr)/Ns×100%

kahi o Nss ka māmā holo synchronous a ʻo Nr ka māmā holo rotor.

He mea koʻikoʻi ka paheʻe no ka hana torque i nā kaʻa induction. Inā hele ka rotor i ka māmā like ʻole, ʻaʻohe neʻe pili ma waena o ke kahua magnetic o ka stator a me ka rotor. Me ka ʻole o kēia neʻe pili ʻana, ʻaʻohe induction electromagnetic e hana ʻia, a no laila, ʻaʻole e hana ʻia kahi torque. ʻO kēia hemahema o ka torque e pau ai ka hana ʻana o ke kaʻa. No laila, pono ka nui o ka paheʻe no ka mīkini e hoʻohua i ka torque i koi ʻia a hana i kāna hana i manaʻo ʻia.

ʻOkoʻa ka nui o ka paheʻe ma muli o ka hoʻolālā kaʻa a me ka ukana i kau ʻia. Ma lalo o nā kūlana haʻahaʻa ʻole, liʻiliʻi ka paheʻe, a kokoke ka wikiwiki rotor i ka wikiwiki synchronous. Ke piʻi aʻe ka ukana, piʻi pū ka paheʻe, e ʻae ana i ke kaʻa e hoʻomohala hou i ka torque e mālama i ka ukana.

ʻO ke kuleana o nā kahua mākēneki i ka hana kaʻa

Ke hilinaʻi nui nei ka hana o nā mīkini synchronous a me induction i ka pilina o nā māla magnetic. In kiʻekiʻe voltage induction motors, hoʻopuka ka stator i ke kahua mākēneki kaʻa i ka wā e hoʻohana ʻia ai kahi voli AC. Ke hoʻoulu nei kēia māhina mākēneki i ke au i loko o ka rotor, e hoʻohua ana i kahi māla magnetic e launa pū me ke kahua o ka stator.

He mea koʻikoʻi ka neʻe pili ʻana ma waena o ke kahua mākēneki wili a ka stator a me ka rotor no ka hoʻoulu ʻana i ke au i loko o ka rotor. Hoʻopuka kēia au i ka torque pono e hoʻohuli i ka rotor. ʻO ka pilina mau ma waena o nā māla magnetic e hōʻoia i ka hana mau o ka kaʻa.

I nā kaʻa kaʻa synchronous, ua hoʻolako ʻia ka rotor me nā magnet mau loa a i ʻole nā ​​​​electromagnets e hana ai i kahi kahua magnetic mau. Hoʻopaʻa ʻia kēia kahua rotor me ke kahua mākēneki kaʻa ʻana o ka stator, e hoʻohuli ai ka rotor i ka wikiwiki synchronous. ʻO ka alignment pololei o nā māla magnetic e hōʻoia i ka holo ʻana o ka kaʻa i ka wikiwiki mau, e hana ana i nā motika synchronous i kūpono no nā noi e koi ana i ka pololei kiʻekiʻe.

Panina

ʻO nā motika induction, ʻoi aku ka hv induction motors, he mau mea koʻikoʻi i ka nui o nā noi ʻoihana ma muli o ko lākou ikaika, hilinaʻi, a me ka pono. ʻO ka hiki ʻole o nā kaʻa induction ke hana i ka wikiwiki synchronous kahi ʻano kumu e hiki ai iā lākou ke hana i ka torque a hana pono. ʻO ka hoʻomaopopo ʻana i nā ʻokoʻa ma waena o nā mīkini synchronous a me induction, ka manaʻo o ka slip, a me ke kuleana o nā māla magnetic e hāʻawi i nā ʻike waiwai i kā lākou hana a me nā pono.

E like me kā mākou i ʻimi ai, ʻo ka ʻokoʻa liʻiliʻi o ka wikiwiki, i kapa ʻia ʻo slip, he mea koʻikoʻi no ka hana ʻana o ka kaʻa induction. Mālama kēia slip i ka hoʻomau ʻana i ka hana torque, e hana ana i nā motika induction maʻalahi a hilinaʻi ʻia no nā noi like ʻole. Ma ka hoʻohana ʻana i nā waiwai kūʻokoʻa o nā motika induction, hiki i nā ʻoihana ke hoʻokō i nā hopena mana kūpono a hilinaʻi.

No ka mea, hou aku no kiʻekiʻe voltage induction motors a me nā mea hana mana ʻē aʻe, e ʻoluʻolu e kelepona iā Shaanxi Qihe Xicheng Electromechanical Equipment Co., Ltd. ma xcmotors@163.com. Hoʻopaʻa mākou i ka hāʻawi ʻana i nā huahana kiʻekiʻe a me ka lawelawe mea kūʻai aku maikaʻi loa e hoʻokō i kāu pono lako mana.
