He aha nā hana o nā palaki kalapona?
2022-11-23
Kapa ʻia ʻo Carbon brush (Carbon brush) i kapa ʻia ʻo ka uila uila, ma ke ʻano he ʻano hoʻoheheʻe ʻana, hoʻohana nui ʻia i nā lako uila. Ua like iki ke ano o ka pulupulu kalapona me ke kaula hao o ka penikala, me na uwea e puka ana mai luna mai, a okoa ka nui. ʻO ka pulupulu kalapona ʻo ia ka ʻāpana o ka mīkini palaki ma ka ʻili o ka commutator. Ke hoʻololi ka motika, hoʻouna ʻia ka ikehu uila i ka wili rotor ma o ka commutator.
ʻO ka pulupulu kalapona he mea ia no ka hoʻoili ʻana i ka ikehu a i ʻole nā hōʻailona ma waena o ka ʻāpana paʻa a me ka ʻāpana ʻōwili o kahi kaʻa a i ʻole nā mea hana ʻē aʻe. ʻO nā mea nui he graphite, momona-impregnated graphite, a me metala (keleawe, kālā) graphite. Hana ʻia ʻo ia me ke kalapona maʻemaʻe me ka coagulant, a ʻo kona helehelena he huinahā. Hoʻopaʻa ʻia ia ma ka bracket metala, a aia kahi pūnāwai i loko e hoʻopaʻa paʻa iā ia ma ke kumu ʻōwili. Ke hoʻololi ka motika, hoʻouna ʻia ka ikehu uila i ka coil ma o ka commutator. ʻOiai ʻo kāna mea nui he kalapona, ua kapa ʻia ʻo ia he kalapona kalapona, kahi maʻalahi e ʻaʻahu. Pono e mālama mau ʻia a hoʻololi ʻia, a e hoʻomaʻemaʻe ʻia nā waihona kalapona.
ʻO ka hana o ka pulupulu kalapona ka mea nui e alakaʻi i ka uila oiai e hamo ana i ka metala; ʻaʻole like ia me ke kuʻekuʻe metala-me-metala; i ka wā e hoʻohenehene ai ke kuʻekuʻe metala; e piʻi aʻe ka ikaika o ka friction; i ka manawa like, kahi e hoʻopaʻa ʻia ai ka hāʻawi ʻana; a ʻaʻole e hana ʻia nā palahū Carbon; no ka mea, ʻelua mau mea like ʻole ke kalapona a me ka metala; ʻo ka hapa nui o kāna hoʻohana ʻia i nā kaʻa; aia nā ʻano like ʻole; he huinaha a poepoe, a pela aku.
Hana kikoʻī:
1. No ka hāʻawi ʻana i ka mana i ka rotor, ua hoʻohui ʻia ke au o waho (excitation current) i ka rotor rotating (input current) ma o ke kalapona kalapona.
2. E hoʻokomo i ka hoʻopiʻi paʻa ma ke kumu nui i ka honua (palapala kalapona i hoʻopaʻa ʻia) ma o ka pulupulu kalapona (ke manawa hoʻopuka).
3. E alakaʻi i ka lāʻau nui (ka honua) i ka mea pale no ka pale ʻana i ka lepo rotor a ana i ka volta maikaʻi a me ka maikaʻi ʻole o ka rotor i ka honua.
4. E hoʻololi i ka ʻaoʻao o kēia manawa (i ka mīkini commutator, hoʻokani pū ka pulupulu i ka hana o ka commutation).
He kūpono nā ʻōpala kalapona no nā ʻano kaʻa like ʻole, nā mīkini hana, a me nā mīkini axle. Loaʻa iā ia ka hana hoʻohuli maikaʻi a me ke ola lawelawe lōʻihi. Hoʻohana ʻia ka pulupulu kalapona ma ka commutator a i ʻole ke apo slip o ke kaʻa. Ma ke ʻano he kino hoʻoheheʻe ʻana e alakaʻi a lawe mai i kēia manawa, loaʻa iā ia ka conductivity uila maikaʻi, conductivity thermal a me ka hana lubricating, a loaʻa iā ia kekahi ikaika mechanical a me ka instinct o ka commutation sparks. Aneane nā kaʻa holoʻokoʻa e hoʻohana i nā pulu kalapona, kahi mea nui o ka kaʻa. Hoʻohana nui ʻia i loko o nā mea hana AC a me DC, nā kaʻa synchronous, nā motika DC DC, nā apo ʻohi kaʻa crane, nā ʻano mīkini welding a pēlā aku. Me ka hoʻomohala ʻana o ka ʻepekema a me ka ʻenehana, ʻoi aku ka nui o nā ʻano o nā kaʻa a me nā kūlana hana o ka hoʻohana.
ʻO ka pulupulu kalapona he mea ia no ka hoʻoili ʻana i ka ikehu a i ʻole nā hōʻailona ma waena o ka ʻāpana paʻa a me ka ʻāpana ʻōwili o kahi kaʻa a i ʻole nā mea hana ʻē aʻe. ʻO nā mea nui he graphite, momona-impregnated graphite, a me metala (keleawe, kālā) graphite. Hana ʻia ʻo ia me ke kalapona maʻemaʻe me ka coagulant, a ʻo kona helehelena he huinahā. Hoʻopaʻa ʻia ia ma ka bracket metala, a aia kahi pūnāwai i loko e hoʻopaʻa paʻa iā ia ma ke kumu ʻōwili. Ke hoʻololi ka motika, hoʻouna ʻia ka ikehu uila i ka coil ma o ka commutator. ʻOiai ʻo kāna mea nui he kalapona, ua kapa ʻia ʻo ia he kalapona kalapona, kahi maʻalahi e ʻaʻahu. Pono e mālama mau ʻia a hoʻololi ʻia, a e hoʻomaʻemaʻe ʻia nā waihona kalapona.
