Nleba anya ihe ndọbatara nke nkedo ime ime

Nyocha ihe ndọta magnetik bụ usoro nchọpụta nke na-eji njirimara nke ihe ferromagnetic (dị ka ígwè, ígwè, cobalt, nickel, wdg) ka ọ bụrụ magnetized. Mgbenkedo ígwèbụ ike magnetized site na ndọta, ma ọ bụrụ na e nwere ntụpọ perpendicular na magnetization direction n'elu ma ọ bụ n'akụkụ elu nke nkedo, akụkụ nke magnetik fields ga-ejupụta ebe a, na-akpụ a leakage magnetik oghere na-emepụta ọhụrụ magnetik okporo osisi. N'oge a, a na-awụsa elu nke nkedo ahụ na mmiri mmiri magnetik kwụsịtụrụ ma ọ bụ fesa ya na ntụ ntụ magnetik akọrọ, na ihe ndọta ntụ ntụ na-egosi ntụpọ nke ntụpọ n'ihi mmasị nke ogwe magnetik.

Mgbe a na-eme nyocha ihe ndọta na nkedo, a na-emepụta ebe ndọta siri ike site n'ịgba ume. Dị ka usoro ume ike dị iche iche na ụdị ebili mmiri dị ugbu a si dị, ụzọ ndọta nwere ike kewaa n'ime magnetization kpọmkwem na magnetization na-apụtaghị ìhè, DC magnetization na AC magnetization. Dị ka ntụziaka e si emepụta oghere ndọta na ụzọ e si emepụta oghere magnetik, e nwere ụzọ magnetization nke nwere ike kewaa n'ime okirikiri magnetik na longitudinal magnetization, magnetization na-aga n'ihu na magnetization fọdụrụnụ. Na nyocha n'ezie, ebe a na-achọta ihe nwere ike ịhọrọ ụzọ dị iche iche nke AC na DC composite magnetization dị ka nha nke nkedo, nkesa nke ntụpọ na ihe ndị ọzọ.

Magnetị ntụ ntụ bụ ihe na-emepụta akara magnetik na-egosi ntụpọ, na ihe ya na-abụkarị ígwè oxide dị elu nke nwere nnukwu ike ndọta, nkwụsị dị ala na mmanye dị ala, dị ka ferric oxide na ferric oxide. Nha urughuru nke magnetik ntụ ntụ ọkacha mma 80 - 300 μm maka usoro nnwale na akọrọ magnetik ntụ ntụ. Maka nyocha mmiri na fluorescent, nha nha nke ntụ ntụ magnet nwere ike ịka mma. Obere ntụpọ nkedo kwesịrị ịhọrọ ezigbo ntụ ntụ magnetik. Ọdịdị nke magnetik ntụ ntụ kwesịrị ịbụ tumadi ntụ ntụ magnetik, wee kwekọọ na akụkụ ụfọdụ nke warara magnetik ntụ ntụ.

Nkwusioru uzuzu magnetik bụ ngwakọta nke ntụ ntụ magnetik na mgbasa n'otu akụkụ. Akụkụ olu nke ntụ ntụ magnetik nkịtị bụ 1.3% - 3.0%, na nha nha nke fluorescent magnetik ntụ ntụ bụ 0.1% - 0.3%. Enwere ike ịhọrọ mmiri mmiri na-agbasa site na onye na-ahụ maka mmiri, kerosene na ngwakọta nke kerosene na mmanụ transformer, nke nwere ike igbochi nchara, wetting na defoaming.

 

Njirimara na oke nke ngwa nyocha ihe ndọta:

1. Nyocha irighiri magnetik nwere mmetụta kachasị elu maka ịchọpụta ntụpọ elu ma ọ bụ nso nso nke nkedo, mana mmetụta ya na-ebelata ngwa ngwa site na mmụba nke omimi ntụpọ.

2. Usoro nchọpụta a na-emetụta naanị nchọpụta nke ihe ferromagnetic, ma enweghị ike iji ya mee ihe nkedo na-abụghị magnetik dị ka austenitic igwe anaghị agba nchara.

3. Akụrụngwa nke nyocha ihe nleba anya magnetik dị mfe, na obere ngwá ọrụ dị mfe iji rụọ ọrụ na saịtị.

4. Nyocha ahụ magnetik nwere ihe dị elu chọrọ na roughness nke nkedo elu.

5. Mgbe nyocha nkedo ahụ gasịrị, ọ dị mkpa iji kpochapụ elu ma wepụ ihe ndọta ndọta na oge. Ọ bụrụ na ọ dị mkpa, a chọrọ ọgwụgwọ demagnetization.
