Magnetick\u00fd tok a plo\u0161n\u00fd gauss<\/h1><\/h1><\/div>

V\u00fdkonnostn\u00e9 testovanie hotov\u00fdch magnetov prim\u00e1rne zis\u0165uje povrchov\u00fa magnetiz\u00e1ciu a magnetick\u00fd tok.<\/p>\n

Povrchov\u00e1 magnetiz\u00e1cia:<\/strong> <\/span>Pou\u017e\u00edva sa povrchov\u00fd magnetometer (gaussmeter, teslameter), ktor\u00fd sa pou\u017e\u00edva na testovanie povrchovej magnetiz\u00e1cie na povrchu magnetu. Jeho sonda m\u00f4\u017ee testova\u0165 iba jeden bod a m\u00f4\u017ee testova\u0165 iba magnetick\u00fa hustotu na tomto mieste v r\u00e1mci jednotkov\u00e9ho objemu magnetu, tak\u017ee jeho \u00fadaje s\u00fa \u00fadajmi jedn\u00e9ho bodu, s\u00fa absol\u00fatnou hodnotou. Niekedy zist\u00edte, \u017ee va\u0161e \u00fadaje st\u00e1le sk\u00e1\u010du. Je to preto, \u017ee kontaktn\u00e1 plocha sondy je trochu ve\u013ek\u00e1, tak\u017ee jej \u00fadaje sa bud\u00fa meni\u0165.<\/p>\n

Magnetick\u00fd tok<\/strong>:<\/span> <\/a>Ide o to, \u017ee magnet sa vlo\u017e\u00ed do Helmoltzovej cievky a potom sa vyberie. Princ\u00edpom je, \u017ee v cievke je kon\u0161tantn\u00e9 magnetick\u00e9 pole. Ke\u010f magnet vlo\u017e\u00edte a potom vyberiete, magnetick\u00e9 pole sa zmen\u00ed. M\u00e1 to vplyv. Zmena medzi magnetick\u00fdm tokom magnetu a p\u00f4vodn\u00fdm magnetick\u00fdm tokom sa d\u00e1 pou\u017ei\u0165 na ur\u010denie hustoty magnetickej energie samotn\u00e9ho magnetu, tak\u017ee ide o relat\u00edvnu hodnotu. Odkazuje sa na energetick\u00e9 \u00fadaje cel\u00e9ho magnetu, nie na \u00fadaje v tomto bode, tak\u017ee v\u00e4\u010d\u0161inu \u010dasu mus\u00edme kombinova\u0165 dve \u00fadaje: magnetick\u00fd tok a povrchov\u00fa magnetiz\u00e1ciu na anal\u00fdzu s\u00fa\u010dasne, jedno je relat\u00edvna hodnota a druh\u00e9 absol\u00fatna hodnota.<\/p>\n

Pri testovan\u00ed povrchovej magnetiz\u00e1cie a magnetick\u00e9ho toku pre\u010do sa v tej istej d\u00e1vke magnetov objavuj\u00fa niektor\u00e9 slab\u0161ie magnetick\u00e9 produkty? V\u017edy bud\u00fa ma\u0165 ni\u017e\u0161\u00ed magnetick\u00fd v\u00fdkon ako be\u017en\u00fd magnet. Ak\u00fd je d\u00f4vod? Pravdepodobne existuj\u00fa \u0161tyri d\u00f4vody:<\/p>\n

1) Ke\u010f sa to deje, v\u00e4\u010d\u0161inou ide o mal\u00e9 produkty, ktor\u00fdch spracovate\u013esk\u00e9 postupy s\u00fa relat\u00edvne dlh\u00e9. Ve\u013emi pravdepodobn\u00e9 je, \u017ee po\u010das spracovania sa do rovnak\u00e9ho d\u00e1vky vysokov\u00fdkonn\u00fdch produktov zamie\u0161aj\u00fa jeden alebo dva produkty s n\u00edzkym v\u00fdkonom. Ak sa produkt na v\u00fdrobnej linke a spracovate\u013eskom z\u00e1vode nepravdivo riadi, tento druh mie\u0161ania sa \u010dasto vyskytuje.<\/p>\n

2) Rob\u00edme tento druh mal\u00fdch produktov. V\u00e4\u010d\u0161ina z nich je vyroben\u00e1 zo \u0161tvorcov\u00e9ho pr\u00e1zdneho tvaru, rozrezan\u00e1 na \u0161tvorce a zaoblen\u00e1, od v\u00e4\u010d\u0161ieho po men\u0161ie. Po\u010das rezania sa v\u0161etka vonkaj\u0161ia poko\u017eka po celej strane naz\u00fdva materi\u00e1l. Ko\u017ea a \u010dierna ko\u017ea sa musia odrez\u00fa\u0165. Niektor\u00e9 fabriky, aby u\u0161etrili n\u00e1klady a materi\u00e1ly, neodstr\u00e1nia dostato\u010dn\u00fa ko\u017eu pri odstra\u0148ovan\u00ed alebo ju re\u017eu \u0161ikmo, \u010do vedie k hor\u0161iemu v\u00fdkonu. Ko\u017eovit\u00fd materi\u00e1l sa na \u0148om bude lepi\u0165, preto\u017ee produkt je relat\u00edvne mal\u00fd a tenk\u00fd, \u010do ovplyvn\u00ed jeho v\u00fdkon.<\/p>\n

3) Takisto sa to m\u00f4\u017ee vyskytn\u00fa\u0165 po\u010das spracovania, teda po\u010das procesu k\u00faskovania, \u017ee do\u0161lo kprekresleniu polariz\u00e1cie magnetiz\u00e1cie. P\u00f4vodne bolo magnetizovan\u00e9 v hr\u00fabke, ale nieko\u013eko st\u013apcov bolo narezan\u00fdch zle a smer magnetiz\u00e1cie sa prejavil ako smer priemeru, \u010do sp\u00f4sobilo, \u017ee t\u00e1to vrstva pri magnetiz\u00e1cii je v\u00fdrazne ni\u017e\u0161ia ako u ostatn\u00fdch.<\/p>\n

4) Toto je naj\u0165a\u017e\u0161ia situ\u00e1cia, toti\u017e jednotnos\u0165 cel\u00e9ho pr\u00e1zdneho kusu nie je dobr\u00e1. Niektor\u00e9 kusy vyroben\u00e9 v tom istom pece maj\u00fa vysok\u00fa a niektor\u00e9 n\u00edzku hodnotu. Rozdiel medzi najvy\u0161\u0161ou a najni\u017e\u0161ou hodnotou je pomerne ve\u013ek\u00fd. To sp\u00f4sob\u00ed nekonzistenciu cel\u00e9ho produktu.<\/p>\n

Preto najprv analyzujte slab\u00e9 magnetick\u00e9 pole vo va\u0161om produkte, ak\u00fd je pomer a ako ve\u013emi je v\u00fdkonnos\u0165 slab\u00e1, a potom postupne zistite skuto\u010dn\u00e9 d\u00f4vody.<\/p>\n

Faktory ovplyv\u0148uj\u00face konzistenciu v\u00fdkonnosti<\/strong> s\u00fa tie\u017e uveden\u00e9 tu.<\/p>\n

V s\u00fa\u010dasnosti m\u00e1 v\u00fdbava ve\u013ek\u00fdch v\u00fdrobcov elektromagnetov len m\u00e1lo rozdielov v zlo\u017een\u00ed surov\u00edn a \u00farovni riadenia. Obtia\u017enos\u0165 spo\u010d\u00edva v kontrole konzistencie v\u00fdkonu ve\u013ek\u00fdch s\u00e9ri\u00ed v\u00fdrobkov.<\/p>\n

1) Materi\u00e1lov\u00fd v\u00fdkon m\u00e1 dobr\u00fa konzistenciu. Jedna d\u00e1vka nabitia vyrob\u00ed pribli\u017ene 500 kg. Je ve\u013ea v\u00fdliskov. Ako zabezpe\u010di\u0165, aby vlastnosti v\u00fdliskov v r\u00f4znych teplotn\u00fdch z\u00f3nach boli konzistentn\u00e9? Aj ke\u010f je v\u00fdkon vonkaj\u0161ej a strednej \u010dasti toho ist\u00e9ho v\u00fdlisku konzistentn\u00fd, treba ho aj tak overi\u0165 a riadi\u0165.<\/p>\n

2) Po\u010das spracovacieho procesu je toleran\u010dn\u00fd rozsah dobre riaden\u00fd, \u010do je n\u00e1pomocn\u00e9 pre kontrolu konzistencie v\u00fdkonu.<\/p>\n

3) Po\u010das elektrolytick\u00e9ho procesu je konzistencia hr\u00fabky povlaku. Ka\u017ed\u00fd krok mus\u00ed by\u0165 vykonan\u00fd do extr\u00e9mu, aby sa zabezpe\u010dila konzistencia v\u00fdkonu kone\u010dn\u00e9ho produktu.<\/p>\n

Nepodie\u013ea sa len na tom, ako vysok\u00fd je v\u00fdkon produktu, ale aj na kontrole konzistencie v\u00fdkonu v s\u00e9ri\u00e1ch v\u00fdrobkov.<\/p>\n<\/div><\/div><\/div><\/div><\/div>","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":1222,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"om_disable_all_campaigns":false,"_monsterinsights_skip_tracking":false,"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[1],"tags":[],"class_list":["post-1224","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-uncategorized"],"jetpack_sharing_enabled":true,"jetpack_featured_media_url":"https:\/\/nbaem.com\/wp-content\/uploads\/2024\/03\/surface-gauss-and-magnetic-flux-e1710742226361.png","_links":{"self":[{"href":"https:\/\/nbaem.com\/sk\/wp-json\/wp\/v2\/posts\/1224","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/nbaem.com\/sk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/nbaem.com\/sk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/nbaem.com\/sk\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/nbaem.com\/sk\/wp-json\/wp\/v2\/comments?post=1224"}],"version-history":[{"count":3,"href":"https:\/\/nbaem.com\/sk\/wp-json\/wp\/v2\/posts\/1224\/revisions"}],"predecessor-version":[{"id":1418,"href":"https:\/\/nbaem.com\/sk\/wp-json\/wp\/v2\/posts\/1224\/revisions\/1418"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/nbaem.com\/sk\/wp-json\/wp\/v2\/media\/1222"}],"wp:attachment":[{"href":"https:\/\/nbaem.com\/sk\/wp-json\/wp\/v2\/media?parent=1224"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/nbaem.com\/sk\/wp-json\/wp\/v2\/categories?post=1224"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/nbaem.com\/sk\/wp-json\/wp\/v2\/tags?post=1224"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
