Pehea e hana ai ka Relay Kaa?

ʻAukake-29-2023

ʻO nā relay kaʻa nā mea nui o nā ʻōnaehana uila automotive.ʻO nā kukui kaʻa, nā wipers, nā mea hoʻomaka, nā ea ea, nā noho uila, nā puka uila a me nā puka makani, nā mea hoʻopaʻa paʻa pale pale, nā mana hoʻokuʻu, nā ʻōnaehana leo, a me nā mea ʻē aʻe e koi i nā relay.ʻO ia kekahi o nā mea uila i hoʻohana pinepine ʻia i loko o nā kaʻa, ma waena o nā relay electromagnetic ka mea mua loa a hoʻohana nui ʻia o ka relay.He aha lākou a pehea lākou e hana ai?Ma kēia ʻatikala, e komo mākou i ka honua o nā relay automotive a e ʻimi i kā lākou mau loina hana a me nā hoʻohana maʻamau.

Pehea e hana ai ka Relay Kaa

1. He aha ke kaʻa kaʻa?

Hoʻohana nui ʻia nā relay kaʻa i nā hoʻololi mana e hoʻomalu i nā au nui me nā au haʻahaʻa ʻoiai e pale ana i nā hoʻololi.ʻO ka mea nui, hiki iā ia ke hoʻomalu i nā ukana mana nui me nā hōʻailona uila liʻiliʻi.Ma muli o ke kiʻekiʻe o ka manawa i koi ʻia, hiki i nā hoʻololi e like me nā pū, nā mea hoʻomaka, nā kukui uila, a me nā mea ʻē aʻe ke hana maʻalahi i ka haʻalulu uila a me ka erosion.Inā loaʻa kahi relay, ʻaʻole liʻiliʻi wale ka nui o ke au e hele ana ma ka hoʻololi mana e hiki ke hoʻoneʻe i ke kua.No laila, ʻōlelo pinepine mākou ʻo nā relays ke alahaka ma waena o nā kaapuni haʻahaʻa haʻahaʻa a me nā kaapuni mana kiʻekiʻe.

2.No ke aha e pono ai nā kaʻa i nā Relay?

Pono nā relay kaʻa no ka mea e ʻae lākou i ka hoʻohana ʻana i nā mea hoʻololi liʻiliʻi a haʻahaʻa a me nā uea i nā kaʻa kaʻa kaʻa.Hiki i kēia ke hoʻemi i ka ukana ma luna o nā kaula uwila kaʻa a me nā hoʻololi, a pale i ka wela nui a me ka pōʻino uila.Eia kekahi, hiki ke kokoke loa ke kūlana o ka relay i nā ʻāpana āna e hoʻomalu ai, a laila e hōʻemi ana i ka hāʻule o ka volta ma nā uea.

3. Hoʻolālā o ka Relay Kaʻa

Hoʻokumu ʻia nā relay kaʻaKoko hao, Coil, YOKE, Armature, Spring, Contact, a pela aku ua maheleia na hoapili iHoʻopili hoʻoneʻeaHoʻopili paʻa.Wahi a ke ʻano o ka hoʻopili ʻana, ua māhele ʻia nā relay i ʻelua ʻano:

1. Make & Break Relay

Ua ʻike ʻia ʻo ia ʻoSPST(Single-Pole, Single-Throw).Aia he 4 pine (a i ʻole ka hopena) ma ke kino me hoʻokahi kaapuni o kēia manawa kiʻekiʻe a me ka pilina.Wehe a pani ʻia ka pilina ma muli o ka hoʻomaha ʻana a i ʻole ka ikaika o ka relay.

● NC:Inā pani ʻia ka mea hoʻopili i ka wā e kū ana ka relay, ua kapa ʻia ka relay ʻo Normally Closed.

4 pine SPST Make & Break Relay

NO: Inā wehe ka hoʻopili i ka wā e paʻa ai ka relay, ua kapa ʻia ka relayWehe maʻamau. ʻO kēia mau relay ka ʻano maʻamau.

2. Hoʻololi Hoʻololi

Ua ʻike ʻia ʻo ia ʻoSPDT(Single-pole, Double-throw).Aia5 pine(a i ʻole nā ​​pahu) ma ke kino, ʻelua mau mea pili i pili i kahi pahu maʻamau.ʻElua mau kaʻapuni o nā relay, pani ʻia kekahi i ka wā e hoʻomaha ai ka relay, a pani ʻia kekahi i ka wā e hoʻoikaika ai ka relay.

5 pine SPDT Changeover Relay

Hōʻike kēia kiʻi i ke ʻano o loko o ka Changeover Relay.

Relay-Kūkulu ʻana i nā Relay Automotive

4. Pehea e hana ai ka Relay Kaa?

Hōʻike ka helu ma lalo nei i ke kaʻina hana o ka relay.No ka maʻalahi o ka hoʻomaopopo ʻana, hāʻawi ʻia kahi relay electromagnetic maikaʻi ma aneʻi.I kēlā me kēia ʻano o ka relay automotive, ʻo nā mea nui ka coil, armature, a me ka pilina.Hoʻopili ʻia kahi uwea a puni ke kumu magnetic, e hana ana i kahi electromagnet.I ka hāʻawi ʻana i ka mana i ka coil, e hoʻoikaika ʻia a hana i kahi kahua electromagnetic.ʻO ka armature kahi mea hiki ke hoʻoneʻe i kāna hana nui ʻo ka wehe a pani ʻana paha i nā pilina.Hoʻopili ʻia me kahi pūnāwai, no laila ma lalo o nā kūlana hana maʻamau, hoʻi ka armature i kona kūlana mua.

1. Moku'āina Mana-Up

Inā hoʻohana ke kumu mana i ka pōʻai, e hoʻoikaika ʻia ka coil electromagnetic o ka relay a hoʻohua i kahi kahe magnetic e like me ke kahe e kahe ana ma loko.Hoʻokomo kēia māla magnetic i ka armature i ka electromagnet, no laila ua pili ka neʻe ʻana a me nā pilina paʻa i kekahi i kekahi, e like me ka mea i hōʻike ʻia ma ke kiʻi aʻe.Ke hoʻoikaika ʻia ka relay, hoʻopili ka NO terminal i ka wā e lana ana ka pilina NC.

 

2.Mokuʻāina hoʻopau mana

Inā ʻaʻohe lako mana i ka relay electromagnetic coil, ʻaʻohe mea hoʻoheheʻe magnetic i hana ʻia, no laila aia ka armature i kahi kūlana paʻa.No laila, ʻaʻole i hoʻololi ʻia nā pilina ʻelua a aia kahi ʻāpana ea liʻiliʻi ma waena o kēia mau pilina.I nā huaʻōlelo ʻē aʻe, pili nā pilina NC me kekahi i ka wā e pio ai ka coil.

5. Hoʻohana maʻamau o nā Relay Kaʻa

He nui nā hoʻohana ʻana o nā relay kaʻa, me:

Mea hoʻomaka:ʻO ka hoʻomaka ʻana i ke kaʻa e pono ai ka nui o ke au e hoʻomaka ai i ka ʻenekini.Hāʻawi ka relay i ka hoʻololi ignition e hoʻomalu i kēia ukana kiʻekiʻe o kēia manawa.

Nā kukui:Hoʻohana mau ʻia nā relays e hoʻomalu i nā kukui, e hōʻoia i ka loaʻa ʻana o ka mana kūpono a me ka pale ʻana i ka hāʻule ʻana o ka volta e hiki ai ke hoʻomoe i nā kukui.

Pahu wahie:Pono ka pauma wahie i ka nui o kēia manawa e hāʻawi i ka wahie i ka ʻenekini.Hoʻomaopopo ka relay e loaʻa iā ia ka mana kūpono.

Kiwi:Pono nā pū kaʻa i ka nui o ke au.Hiki i ka relay ke hoʻomalu i ka pū kani.

 

Hiki ke ʻōlelo ʻia ʻo nā relay kaʻa he poʻe koa ʻole i ka ʻoihana kaʻa.Hāʻawi lākou i kahi ala kūpono a maikaʻi hoʻi e hoʻokele i kēia manawa i loko o kahi kaʻa, e ʻae iā ʻoe e mana i nā ʻāpana kiʻekiʻe o kēia manawa me ka ʻole o ka hoʻouka ʻana i ka ʻōnaehana uila.Hāʻawi ʻo Typhoenix i kahi ākea ākeanā kaʻa kaʻae pale i kou kaʻa.

Kekahi nīnau, e ʻoluʻolu eKāhea iā mā˚ou i kēia manawa:
