ʻO nā mea ʻike maʻamau i hoʻohana ʻia no nā kaʻa uila e pili ana: ka mea ana ke ana wela o ka stator, ka mea e ana ana i ka mahana, ka mea ʻike leakage wai, ka pale ʻana o ka stator winding grounding differential, etc.Hoʻolako ʻia kekahi mau kaʻa nui me nā shaft vibration detection probes, akā ma muli o ka haʻahaʻa haʻahaʻa a me ke kumukūʻai kiʻekiʻe, liʻiliʻi ke koho.
• E pili ana i ka mālama ʻana i ka wela o ka stator a me ka pale ʻana i ka wela: hoʻohana kekahi mau mīkini haʻahaʻa haʻahaʻa i nā thermistors PTC, a ʻo ka mahana pale he 135 ° C a i ʻole 145 ° C.Hoʻokomo ʻia ka wili stator o ka mīkini uila kiʻekiʻe me 6 Pt100 platinum thermal resistors (ʻekolu-wire system), 2 i kēlā me kēia pae, 3 hana a me 3 standby.
• E pili ana i ka mālama ʻana i ka wela a me ka pale ʻana i ka wela: ua hāʻawi ʻia kēlā me kēia ʻano o ke kaʻa me ka Pt100 pālua platinum thermal resistance (ʻekolu-wire system), ka huina o 2, a ʻo kekahi mau motika pono wale nō ka hōʻike wela ma ka pūnaewele.ʻAʻole pono e ʻoi aku ka mahana o ka pahu lawe kaʻa ma mua o 80 ° C, ʻo ka mahana hoʻāla he 80 ° C, a ʻo ka mahana pani ʻana he 85 ° C.ʻAʻole pono e ʻoi aku ka mahana o ka lawe kaʻa ma mua o 95 ° C.
• Hāʻawi ʻia ke kaʻa me nā mea e pale ai i ka leakage wai: no ka mīkini hoʻoluʻu wai me ka wai hoʻoluʻu wai luna, ua hoʻokomo pinepine ʻia kahi hoʻololi ʻike leakage wai. Ke lele ka mea hoʻomaʻamaʻa a i ʻole ka nui o ka leakage, e hoʻopuka ka ʻōnaehana hoʻomalu i kahi alarm.
• Ka pale ʻokoʻa ʻana o nā wili stator: E like me nā kūlana ʻāina kūpono, ke ʻoi aku ka mana o ka kaʻa ma mua o 2000KW, pono e hoʻolako ʻia nā wili stator me nā mea pale pale ʻokoʻa.
Pehea ka hoʻokaʻawale ʻia ʻana o nā lako kaʻa?
Mea hoʻokele kaʻa
ʻO ka stator kaʻa he ʻāpana koʻikoʻi o nā kaʻa e like me nā mea hana a me nā mea hoʻomaka.He ʻāpana koʻikoʻi ka stator o ke kaʻa.ʻO ka stator he ʻekolu ʻāpana: stator core, stator winding and frame.ʻO ka hana koʻikoʻi o ka stator ka hoʻoulu ʻana i kahi māla magnetic rotating, a ʻo ka hana nui o ka rotor e ʻoki ʻia e nā laina magnetic o ka ikaika i loko o ke kahua magnetic rotating e hoʻohua i kēia manawa.
kaʻa kaʻa
ʻO ka rotor kaʻa ʻo ia hoʻi ka ʻāpana wili i loko o ke kaʻa.He ʻelua ʻāpana ka motika, ka rotor a me ka stator. Hoʻohana ʻia ia e ʻike i ka mea hoʻololi ma waena o ka ikehu uila a me ka ikehu mechanical a me ka ikehu mechanical a me ka ikehu uila.Hoʻokaʻawale ʻia ka rotor kaʻa i ka rotor kaʻa a me ka rotor generator.
wili stator
Hiki ke hoʻokaʻawale ʻia ka wili stator i ʻelua ʻano: kikowaena a hoʻohele ʻia e like me ke ʻano o ka wili wili a me ke ʻano o ka wili i hoʻopili ʻia.He mea maʻalahi ka wili a me ka hoʻopili ʻana o ka wili waena, akā haʻahaʻa ka maikaʻi a maikaʻi ʻole ka hana holo.I kēia manawa, ʻo ka hapa nui o nā stators o nā kaʻa AC e hoʻohana i nā wili puʻupuʻu. Wahi a nā hiʻohiʻona like ʻole, nā hiʻohiʻona a me nā kūlana kaʻina o ka wili wili, ua hoʻolālā ʻia nā motika me nā ʻano wili like ʻole a me nā kikoʻī, no laila ʻokoʻa nā ʻano ʻenehana o nā wili.
hale kaʻa
ʻO ka pahu kaʻa kaʻa e pili ana i ka pahu waho o nā mea uila a me nā lako uila.ʻO ka pahu kaʻa ka mea pale o ke kaʻa, i hana ʻia me ka silicon steel sheet a me nā mea ʻē aʻe ma ke kahakaha ʻana a me ke kaʻina huki hohonu.Eia kekahi, hiki i ka ʻili anti-rust a me ka pulupulu a me nā kaʻina hana ʻē aʻe ke pale maikaʻi i nā lako o loko o ka kaʻa.Nā hana nui: pale lepo, anti-noise, wai ʻole.
pāpale hope
ʻO ka uhi hope he uhi hope i hoʻokomo ʻia ma hope o ka pahu o ke kaʻa, i ʻike nui ʻia ʻo "ka uhi hope", kahi i haku ʻia me kahi kino uhi, kahi bearings, a me kahi pulupulu uila.Inā maikaʻi a maikaʻi ʻole paha ka uhi hope e pili pono ana i ka maikaʻi o ke kaʻa.ʻO ka uhi hope maikaʻi ka mea nui mai kona puʻuwai - ka pulupulu, ʻo kāna hana ka hoʻokele ʻana i ka rotation o ka rotor, a ʻo kēia ʻāpana ke kī nui.
ʻO nā pahi hoʻokele kaʻa
Aia ma ka huelo o ke kaʻa nā ʻāpana peʻahi o ke kaʻa a hoʻohana ʻia no ka ventila a me ka hoʻoluʻu ʻana o ke kaʻa. Hoʻohana nui ʻia lākou ma ka huelo o ke kaʻa AC, a i ʻole ke kau ʻia i loko o nā ducts ventilation kūikawā o ka DC a me nā motika kiʻekiʻe.Hana ʻia nā ʻili o nā kaʻa pahū-hōʻike i ka plastic.
E like me ka hoʻokaʻawale ʻana o nā mea: hiki ke hoʻokaʻawale ʻia nā ʻūhā kaʻa kaʻa i ʻekolu mau ʻano, a me nā ʻili palaki palaki, nā ʻāpana pā alumini hoʻolei, nā ʻāpana pā hao.
hali
He mea koʻikoʻi nā bearings i nā mīkini a me nā mea hana o kēia wā.ʻO kāna hana nui, ʻo ia ke kākoʻo i ke kino rotating mechanical, hoʻemi i ka coefficient friction i ka wā o kona neʻe ʻana, a hōʻoia i ka pololei o ka rotation.
Hoʻokumu ʻia nā bearings ʻehā i ʻehā mau ʻāpana: ke apo o waho, ke apo i loko, ke kino holo a me ka hale. ʻO ka ʻōlelo koʻikoʻi, ua haku ʻia ʻo ia i ʻeono mau ʻāpana: ke apo o waho, ke apo i loko, ke kino ʻōwili, ka hale, ke sila a me ka ʻaila lubricating.ʻO ka mea nui me ke apo o waho, ke apo i loko a me nā mea ʻōwili, hiki ke wehewehe ʻia e like me ka rolling bearing.E like me ke ʻano o nā mea ʻōwili, ua hoʻokaʻawale ʻia nā bearings rolling i ʻelua mau ʻāpana: ball bearings a me roller bearings.
