Kedu ka esi eme ihe banyere nfefe ngwa ngwa induction dị elu?
Olee otú obibi overcurrent nke igwe eji agba oku igba oku?
Ihe kpatara igwe kpo oku dị elu na-arị elu bụ:
1. Igwe mkpuchi induction nke ejiri aka ya mee onwe ya nwere ọdịdị na nha na-ezighi ezi, ebe dị anya n’etiti workpiece na eriri induction dị ntakịrị, enwere obere sekit n’etiti ihe na-arụ ọrụ na eriri induction ma ọ bụ eriri induction n’onwe ya, na eriri induction a kwadebere. na-emetụta ihe nrụnye igwe nke onye ahịa n’oge eji ma ọ bụ Mmetụta nke ihe ọla dị nso, wdg.
Agbabịa:
1. Megharịa eriri induction. Oghere njikọ dị n’etiti eriri induction na akụkụ kpo oku kwesịrị ịbụ 1-3mm (mgbe ebe a na-ekpo ọkụ dị ntakịrị), na eriri induction kwesịrị emerụ ya na tube ọla kọpa gburugburu ma ọ bụ tube ọla kọpa square nwere ọkpụrụkpụ nke 1-1.5mm na n’elu φ5;
2. Lelee ma ike kpo oku dabara na ihe nchekwa. Ọ bụrụ na egwuregwu ahụ ziri ezi, lelee ma ọrụ ahụ ọ bụ eziokwu, ọkachasị oge kpo oku;
3. Mgbe ihe ndị na-adịghị mma magnetik dị ka ọla kọpa na aluminom na-ekpo ọkụ na-ekpo ọkụ, ọnụ ọgụgụ nke induction coils kwesịrị ịba ụba;
4. Akụrụngwa kwesịrị izere ìhè anyanwụ, mmiri ozuzo, iru mmiri, wdg;
5. Gbanwee na mgbanwe nchekwa nchekwa buru ibu, ma ọ bụrụhaala na usoro kpo oku bụ ihe nkịtị.
Abụọ, mmalite na-agabiga ókè
1. IGBT mmebi
2. Ọkwọ ụgbọ ala ọdịda
3. Ihe kpatara ya site na ịhazi obere mgbanaka magnetik
4. Igwe sekit dị mmiri
5. Ike ọkọnọ nke bọọdụ mbanye bụ ihe na-adịghị mma
6. Obere sekit nke ihe mmetụta
Agbabịa:
1. Dochie bọọdụ ọkwọ ụgbọ ala na IGBT, wepụ obere mgbanaka magnetik na ndu, lelee ụzọ mmiri, ma ọ bụrụ na egbochiri igbe mmiri, fesaa bọọdụ ejiri igwe na-ehicha ntutu, wee tụọ voltaji;
2. Overcurrent mgbe eji maka oge nke oge mgbe booting: ihe kpatara ya bụ n’ozuzu ogbenye okpomọkụ dissipation nke ọkwọ ụgbọala. Usoro ọgwụgwọ: tinyeghachi griiz silicone; lelee ma akpọchiela ụzọ mmiri.
Atọ, ike na-abawanye karịa ugbu a
1. Mgbanye ntụgharị
2. Ihe mmetụta adịghị adaba
3. Ọkwọ ụgbọ ala ọdịda
Agbabịa:
1. N’ime igwe na eriri induction ga-eme ka mmiri dị jụụ, isi mmiri ahụ ga-adịkwa ọcha, ka ọ ghara igbochi ọkpọkọ jụrụ oyi ma mee ka igwe ahụ kpoo ọkụ ma mebie ya. Ọnọdụ okpomọkụ nke mmiri jụrụ oyi ekwesịghị ịdị elu, ọ kwesịrị ịdị ala karịa 45 ℃;
2. Ejila teepu akụrụngwa enweghị mmiri mgbe ị na-etinye eriri induction ka ịzena njikọ eletrik adịghị mma. Agbanwela induction eriri igwe ka ọ bụrụ brazing ma ọ bụ ịgbado ọkụ;
3. Enwere ọtụtụ ihe kpatara mmetụta nke ọnụọgụ ntụgharị nke eriri induction na nke dị ugbu a, ọ nwekwara ike ime ka ọ gbasaa.
