Sonda sa poate testa numai un punct, iar nivelul densit\u0103\u021bii de c\u00e2mp magnetic \u00een acea pozi\u021bie din volumul unit\u0103\u021bii magnetului poate fi testat doar acolo, deci datele sale reprezint\u0103 datele pentru un singur punct, fiind o valoare absolut\u0103. Uneori ve\u021bi observa c\u0103 datele dvs. sare mereu \u00een jur. Acest lucru se \u00eent\u00e2mpl\u0103 deoarece zona de contact a sondei este pu\u021bin mare, a\u0219a c\u0103 datele sale se vor schimba.<\/p>\n<p><a href=\"https:\/\/nbaem.com\/ro\/how-to-measure-magnet-strength\/\"><span style=\"color: #0000ff;\"><strong>Flux magnetic<\/strong>:<\/span> <\/a>Este vorba despre a introduce magnetul \u00eentr-un tambur Helmholtz \u0219i apoi a-l scoate. Principiul este c\u0103 \u00een tambur exist\u0103 un c\u00e2mp magnetic constant. C\u00e2nd introduce\u021bi magnetul \u0219i apoi \u00eel scoate\u021bi, c\u00e2mpul magnetic se va modifica. Aceasta are un impact. Modificarea dintre c\u00e2mpul magnetic al magnetului \u0219i c\u00e2mpul magnetic ini\u021bial poate fi folosit\u0103 pentru a determina densitatea energiei magnetice a magnetului \u00een sine, deci este o valoare relativ\u0103. Se refer\u0103 la energia datelor \u00eentregului magnet, nu la datele de la acest punct, a\u0219a c\u0103 majoritatea timpului trebuie s\u0103 combin\u0103m cele dou\u0103 date ale fluxului magnetic \u0219i magnetismului de suprafa\u021b\u0103 pentru a analiza \u00een acela\u0219i timp, unul fiind valoare relativ\u0103 iar cel\u0103lalt valoare absolut\u0103.<\/p>\n<p>Atunci c\u00e2nd se testeaz\u0103 magnetismul de suprafa\u021b\u0103 \u0219i fluxul magnetic, de ce apar unele produse magnetice slabe \u00een acela\u0219i lot de magne\u021bi? \u00centotdeauna va exista o performan\u021b\u0103 magnetic\u0103 mai mic\u0103 dec\u00e2t a unui magnet normal. Care este motivul? Probabil exist\u0103 patru motive:<\/p>\n<p>1) C\u00e2nd se \u00eent\u00e2mpl\u0103 acest lucru, majoritatea sunt produse mici, iar procedurile lor de prelucrare sunt relativ lungi. Este foarte probabil ca \u00een timpul prelucr\u0103rii unul sau dou\u0103 produse cu performan\u021b\u0103 redus\u0103 s\u0103 se amestece \u00een acela\u0219i lot de produse cu performan\u021b\u0103 \u00eenalt\u0103. Dac\u0103 produsul nu este gestionat riguros la sediul de produc\u021bie \u0219i la una dintre fabrici, acest tip de amestecare se va \u00eent\u00e2mpla adesea.<\/p>\n<p>2) Facem acest tip de produse mici. Majoritatea sunt realizate dintr-un blank p\u0103trat, t\u0103iat \u00een p\u0103trate \u0219i rotunjit, de la mare la mic. \u00cen timpul procesului de t\u0103iere, toat\u0103 pielea exterioar\u0103 de pe \u00eentreaga latur\u0103 este numit\u0103 material. Pielea \u0219i pielea neagr\u0103 trebuie s\u0103 fie t\u0103iate. Unele fabrici, pentru a reduce costurile \u0219i materialele, nu \u00eendep\u0103rteaz\u0103 suficient\u0103 piel\u0103 atunci c\u00e2nd o \u00eendep\u0103rteaz\u0103, sau o taie oblic, ceea ce duce la performan\u021b\u0103 slab\u0103. Materialul pielii se va lipi de el deoarece produsul este relativ mic \u0219i sub\u021bire, ceea ce va afecta performan\u021ba sa.<\/p>\n<p>3) \u00cenc\u0103 apare \u00een timpul prelucr\u0103rii, adic\u0103 \u00een timpul procesului de t\u0103iere, c\u0103 l-au inversat polaritatea magnetiz\u0103rii. Ini\u021bial a fost magnetizat \u00een direc\u021bia grosimii, dar mai multe coloane au fost t\u0103iate gre\u0219it, iar direc\u021bia magnetiz\u0103rii a fost t\u0103iat\u0103. A devenit direc\u021bia diametrului, f\u0103c\u00e2nd ca aceast\u0103 pelicul\u0103 s\u0103 fie semnificativ mai mic\u0103 dec\u00e2t celelalte \u00een timpul magnetiz\u0103rii.<\/p>\n<p>4) Aceasta este cea mai dificil\u0103 situa\u021bie, adic\u0103 uniformitatea \u00eentregului blank nu este bun\u0103. Unele blankuri produse \u00een acelea\u0219i cuptoare sunt \u00eenalte, altele joase. Eroarea dintre cel mai \u00eenalt \u0219i cel mai sc\u0103zut este relativ mare. Acest lucru va rezulta \u00een o consisten\u021b\u0103 slab\u0103 a \u00eentregului produs.<\/p>\n<p>Prin urmare, mai \u00eent\u00e2i analiza\u021bi c\u00e2mpul magnetic slab din produsul dvs., ce propor\u021bie are, c\u00e2t de pu\u021bin performan\u021ba este slab\u0103, \u0219i apoi identifica\u021bi adev\u0103ratele motive unul c\u00e2te unul.<\/p>\n<p>Factorii care influen\u021beaz\u0103 <strong>consecven\u021ba performan\u021bei<\/strong> sunt de asemenea introdu\u0219i aici.<\/p>\n<p>\u00cen prezent, echipamentul produc\u0103torilor mari de magneti are pu\u021bine diferen\u021be \u00een formularea materiilor prime \u0219i \u00een nivelul de gestionare. Dificultatea este de a controla consisten\u021ba performan\u021bei \u00eentregului lot de produse.<\/p>\n<p>1) Performan\u021ba materialului are o consisten\u021b\u0103 bun\u0103. Un lot de \u00eenc\u0103rc\u0103tur\u0103 produce aproximativ 500KG. Exist\u0103 multe goale. Cum s\u0103 se asigure c\u0103 propriet\u0103\u021bile goaleor din zonele de temperatur\u0103 diferite sunt consistente? Chiar dac\u0103 performan\u021ba p\u0103r\u021bilor exterioare \u0219i interioare ale aceleia\u0219i goale este constant\u0103, tot trebuie verificat\u0103 \u0219i controlat\u0103.<\/p>\n<p>2) \u00cen timpul procesului de prelucrare, intervalul de toleran\u021b\u0103 este bine controlat, ceea ce ajut\u0103 la controlul consisten\u021bei performan\u021bei.<\/p>\n<p>3) \u00cen timpul procesului de electrozilare, consisten\u021ba grosimii stratului. Fiecare pas trebuie efectuat la extrem pentru a asigura consisten\u021ba performan\u021bei produsului final.<\/p>\n<p>Nu este vorba doar despre c\u00e2t de \u00eenalt\u0103 este performan\u021ba produsului, ci \u0219i despre controlul consisten\u021bei performan\u021bei \u00een produse \u00een loturi.<\/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\/ro\/wp-json\/wp\/v2\/posts\/1224","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/nbaem.com\/ro\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/nbaem.com\/ro\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/nbaem.com\/ro\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/nbaem.com\/ro\/wp-json\/wp\/v2\/comments?post=1224"}],"version-history":[{"count":3,"href":"https:\/\/nbaem.com\/ro\/wp-json\/wp\/v2\/posts\/1224\/revisions"}],"predecessor-version":[{"id":1418,"href":"https:\/\/nbaem.com\/ro\/wp-json\/wp\/v2\/posts\/1224\/revisions\/1418"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/nbaem.com\/ro\/wp-json\/wp\/v2\/media\/1222"}],"wp:attachment":[{"href":"https:\/\/nbaem.com\/ro\/wp-json\/wp\/v2\/media?parent=1224"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/nbaem.com\/ro\/wp-json\/wp\/v2\/categories?post=1224"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/nbaem.com\/ro\/wp-json\/wp\/v2\/tags?post=1224"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
