Ka manawa: 2021-05-11 Nā Hits: 8

ʻEkolu mau ʻāpana o ka pauma ʻume mākenēki: he pauma, he hoʻokele uila, a me kahi motika. ʻO ka mea nui o ka hoʻokele kūpili me kahi rotor ʻume mākenēki waho, kahi rotor ʻume mākenēki o loko a me kahi lole hoʻokaʻawale non-ʻume mākenēki. Ke hoʻokau ka motika i ka rotor ʻume mākenēki waho e hoʻohuli, hiki i ka māla ʻume mākenēki ke komo i ka hakahaka o ka ea a me nā mea non-magnet, a hoʻokau i ka rotor ʻume mākeke i loko e pili ana i ka impeller e kaʻanalike, hoʻomaopopo i ka lawe ʻole o ka mana me ka hoʻohuli ʻole. sila i ka sila paʻa. Ma muli o ka paʻa o ka pauma pauma a me ka rotor ʻume mākenēki i ka kino o ka pauma a me ka lima hoʻokaʻawale, ua pau ka pilikia o ka "holo, ka hoʻokuʻu ʻana, ka kulu ʻana, a me ka liu ʻana", a me ke kahe o ka pāpāho hoʻopā, nā mea pahū, ʻawahia, a me nā mea hoʻopōʻino ma hoʻopau ʻia ka hoʻomaʻemaʻe a me ka ʻoihana kemika ma o ka sila pauma. ʻO nā mea palekana palekana hiki ke hōʻoia pono i ke olakino a me ke olakino a me ka palekana o ka hana o nā limahana.

1. Ke kumu hana o ka pump pump
N hui lua nā mākēneki (n he helu kaulike) i ʻākoakoa ʻia i nā rotors ʻume mākenēki o loko a me waho o ka mea hoʻoiho ʻume mākenēki i kahi hoʻonohonoho maʻamau, i mea e hana ai nā ʻāpana Mākēneka i kahi ʻōnaehana magnet i hui pū ʻia kekahi me kekahi. Ke kūʻē ana nā kia ʻume mākenēki o loko a me waho, ʻo ia hoʻi, ke kihi hoʻoneʻe ma waena o nā pou manamana ʻelua Φ = 0, ʻo ka ikehu ʻume mākeneka o ka ʻume mākeneka ka mea haʻahaʻa loa i kēia manawa; ke kaʻapuni nā pou manamana i ka pou like, ke kihi hoʻoneʻe ma waena o nā pou manamana ʻelua = 2π / n, ʻoi aku ka nui o ka ikehu ʻume mākenēki i kēia manawa. Ma hope o ka hemo ʻana o ka ikaika kūwaho, no ka mea, kipaku nā pou manō o ka ʻōnaehana ʻume mākenēki i kekahi i kekahi, e hoʻihoʻi ka ikaika Mākēneki i ka mākēneki i ka mokuʻāina ikehu haʻahaʻa loa. A laila neʻe nā mākēneki, hoʻokele i ka rotor ʻume mākenēki e huli

2. Nā hiʻohiʻona kūkulu
1. Mākēneki paʻa
Nā mākēneki paʻa i hana ʻia i nā mea magnet mau o ka honua i loaʻa i kahi ākea mahana pāhana hana (-45-400 ° C), coercivity kiʻekiʻe, a me anisotropy maikaʻi i ke kuhikuhi o ka māla magnet. ʻAʻole hiki i ka Demagnetization ke kokoke ka mau kia like. He kumu maikaʻi ia o ka mākia mākala.
2. Pahu hoʻokaʻawale
Ke hoʻohana ʻia ka lima lima hoʻokaʻawale metala, aia ka lima hoʻokaʻawale i loko o kahi mākia magnet alternating sinusoidal, a ua hoʻokomo ʻia ke au o eddy i ka paukū e pili ana i ke kuhikuhi o ka laina ikaika a hoʻohuli ʻia i wela. ʻO ka manaʻo o eddy current: ma kahi o Pe-eddy current; K-kūmau; n-helu ʻia ka wikiwiki o ka pauma; Kaha hoʻoili uila T-ʻume mākenēki; F-puʻe i ka spacer; D-loko o ke anawaena o ka spacer; resistivity o kahi mea; -material Ka ikaika ikaika. Ke hoʻolālā ʻia ka pauma, hāʻawi ʻia n a me T e nā kūlana hana. No ka hoʻoliʻiliʻi i ke au o eddy hiki ke noʻonoʻo wale ʻia mai nā ʻaoʻao o F, D, a pēlā aku. Hana ʻia ka lima hoʻokaʻawale i nā mea hao ʻole me ka resistivity kiʻekiʻe a me ka ikaika kiʻekiʻe, ka mea e maikaʻi loa i ka hōʻemi ʻana i kēia au o eddy.

3. Kaohi o ke kahe ʻana o ka lubricant
Ke holo nei ka pauma ʻumeʻume, pono e hoʻohana i kahi wai liʻiliʻi e holoi a hoʻomaʻalili i ka wahi āpau annular ma waena o ka rotor ʻume mākeke i loko a me ka lima hoʻokaʻawale a me nā paio ʻelua o ka hāpai kahe ʻana. ʻO ke kahe kahe o ka coolant ʻo 2% -3% o ke ana kahe o ka pauma. ʻO ka wahi annulus ma waena o ka rotor ʻume mākenēki o loko a me ka lima hoʻokaʻawale e hoʻoulu i ka wela nui ma muli o nā kahe o eddy. Ke lawa ʻole ka lubricant anuanu a ʻaʻole i laumania a paʻa ʻia ka lua paheʻe, e ʻoi aku ka kiʻekiʻe o ka mahana ma mua o ka mahana hana o ka magnet mau, a e lilo ka magnetic rotor i loko i kāna magnetism a e holo pono ʻole ka drive magnet. Ke holo ka wai ma waena o ka wai a me ka wai o ka wai, hiki ke mālama ʻia ka piʻi ʻana o ka mahana ma kahi o ka annulus ma 3-5 ° C; ke hydrocarbon a ʻaila paha ka mea waena, hiki ke mālama ʻia ka piʻi ʻana o ka mahana ma kahi o ka anulus ma 5-8 ° C.

4. ʻO ka hoʻoheheʻeʻana
Hoʻopili ʻia nā mea o nā paheʻe paheʻe o nā pumps magnet i ka graphite, hoʻopihapiha ʻia me polytetrafluoroethylene, ʻenekini ceramics a pēlā aku. Ma muli o ke kūpale maikaʻi ʻana o ka ʻenekinia cerosion, kūpaʻa ka popopo, a me ke kūpaʻa kūpikipiki, ʻo nā bearings paheʻe o nā pump pump he nui i hana ʻia i nā ceramics ʻenehana. Ma muli o ka palupalu o ka hana ʻana i nā ceramics a loaʻa kahi koena lawa hoʻonui, ʻaʻole pono e ʻemi ka lawe ʻana e pale i nā ulia pōpilikia.
Ma muli o ka hoʻoheheʻe ʻana o ka paheʻe pākēneka e ka mea lawe i lawe ʻia, pono e hoʻohana i nā mea like ʻole e hana i nā bearings e like me nā pāpāho like ʻole a me nā kūlana hana.

5. Nā hana pale
Ke holo nei ka ʻāpana kipaku o ka hoʻokalakupua ma lalo o ka overload a paʻa paha ka rotor, e heʻe pahemo nā mea nui a kipaku ʻia o ka drive magnet e pale i ka pauma. I kēia manawa, e hana ka maneto paʻa ma ka mea hoʻoiho ʻume mākenēki i ka nalo ʻana a me ka nalo ʻana o ka magnet ma lalo o ka hana o ke kahua magnetic alternating o ka rotor ʻeleu, kahi e piʻi ai ka mahana o ka Mākēneki paʻa mau a hoʻoheheʻe ka actuator magnet .
ʻEkolu, nā mea maikaʻi o ka pump pump
Hoʻohālikelike ʻia me nā pauma centrifugal e hoʻohana i nā sila mechanical a i ʻole nā ​​sila hoʻopili ʻana, loaʻa i nā pumps magnet nā mea maikaʻi aʻe.
1. Hoʻololi ka ʻau o ka pauma mai kahi sila paʻa i kahi sila paʻa paʻa, e pale loa ana i ka kahe ʻana o ka waena.
2. ʻAʻole pono ka lubrication kūʻokoʻa a me ka wai anuanu, kahi e hōʻemi ai i ka hoʻohana ʻana i ka ikehu.
3. Mai ka hoʻopili ʻana o ka hoʻopili ʻana i ka drag sink, ʻaʻohe pilina a me ka hakakā. Loaʻa ka liʻiliʻi o ka mana, kiʻekiʻe pono, a he hopena hoʻoliʻiliʻi a hoʻoweliweli, kahi e hōʻemi ai i ka hopena o ka haʻalulu o ka motika ma ka pauma ʻumeʻume a me ka hopena o ka motika ke loaʻa ka pauma i ka haʻalulu cavitation.
4. Ke hoʻouka nui ʻia, paheʻe ke ʻano o nā rotors magnet o loko a me waho, kahi e pale ai i ka motika a me ka pauma.
ʻEhā, nā hana hoʻomalu
1. Pale i nā ʻāpana mai ke komo ʻana
(1) ʻAʻohe ʻae ʻia nā impurities Ferromagnetic a me nā ʻāpana e komo i ka pauma pume ʻume mākenēki a lawe i nā paʻa hakakā.
(2) Ma hope o ka lawe ʻana i ka meakino maʻalahi e crystallize a i ʻole piʻi, e hoʻolei i ka manawa (ninini i ka wai maʻemaʻe i loko o ka lua o ka pauma ma hope o ke kū ʻana o ka pauma, a hoʻokahe iā ia ma hope o 1 min o ka hana) e hōʻoia i ke ola lawelawe o ka heʻe paheʻe .
(3) Ke lawe nei i ka waena me nā huna paʻa paʻa, pono e kānana ʻia ma ke komo o ka paipu kahe o ka pauma.
2. Kāohi i ka demagnetization
(1) ʻAʻole hiki ke hoʻolālā i ka ikehu pauma uila i ka liʻiliʻi.
(2) E hana ʻia ia ma lalo o nā kūlana wela i ʻōlelo ʻia, a pāpā loa ʻia ka mahana waena ma mua o ke kūlana. Hiki ke hoʻouka ʻia kahi mea hoʻopili pāhana kūpale platinum ma ka ʻaoʻao i waho o ka lole hoʻokaʻawale ʻume mākeneka e ʻike i ka piʻi ʻana o ka mahana ma ka wahi anulus, i hiki ai iā ia ke hoʻoweliweli a i ʻole ke pani ʻia ke ʻoi aku ka mahana i ka palena.
3. Kāohi i ka hakakā maloʻo
(1) pāpā loa ʻia ka idling.
(2) Pāpā loa ʻia ka neʻe ʻana mai ka medium.
(3) Me ka puka o ka puka i pani ʻia, ʻaʻole pono e holo mau ka pauma no ʻoi aku ma mua o 2 mau minuke e pale ai i ka mea hoʻoulu uila mai ka wela a me ka hāʻule.
