Mibvunzo Inobvunza Mainjiniya Kazhinji
Mubvunzo: Ko magineti yekubatanidza inogona kunyatso zadzisa IP68, kana pane sirin'i inoshanda?
A: Hongu, IP68 inogoneka, asi kudzika kwacho kunokosha. Chisimbiso chechiso chinokwana IP68 pa3m. Kune IP68 pa10m kana kupfuura, labyrinth-yakabatsirwa dhizaini ndiyo nzira inovimbika, yakasanganiswa nekutonga kwakasimba kweO-ring groove kumashure{9}}kucheneswa kudzivirira gap extrusion pasi pe0.2 MPa+ hydrostatic load.

Chisungo ndechekuisa chisimbiso kumeso chaiko uye groove geometry, kwete iyo magineti musimboti pachayo.
Mubvunzo: Iyo Magnetic Connector Diameter 4.5mm Smart Ring inogona kusvika IP68?
A: Inogoneka nehunyanzvi asi yakanyanya kuoma pane yekubatanidza mahombe. Pa 4.5mm OD, upamhi hwechisimbiso hunoshanda huri pasi pe1mm, uye O-dhayamita yewaya yemhete i0.4–0.6mm. Kuchengeta IP68 pachikero ichi kunoda kuvharisa kudzikama kwechiso muchikamu che 0.005–0.01mm uye kushata kwepamusoro Ra Zvishoma pane kana kuenzana ne0.4μm - zvinogoneka mukugadzira nemazvo asi zvinoda danho rekuongorora rakazvipira. Mazhinji ekugadzira akangwara ring charger anonangwa IP67 (1m / 30 maminetsi); IP68 inoda 100%.
Mubvunzo: Ndinosimbisa sei kuti simba remagineti rakasimba zvakakwana kuchengetedza chisimbiso?
A: Verenga mumatanho matatu: chekutanga, fungidzira O-simba rekusimbisa mhete (O-ringi perimeter × muchinjiko-kuoma kwechikamu pakutsikirirwa kwekugadzira); chechipiri, chidimbu chizere chepogo pini chitubu simba; chechitatu, wedzera nhamba yakasanganiswa ne 1.5 kuitira kuchengetedza chinhu. Izvo zvinopa mashoma anodiwa magineti ekuvhara simba. Wobva wayera dhonza chairo-kubvisa simba negeji yesimba woona kuti inodarika zvishoma. Chakakosha chiziviso: gara uchiita ongororo iyi nekusvibiswa kwakafananidzirwa pazviso zvinosangana - ferromagnetic tsvina iri pamusoro inoderedza kushandiswa kwemagineti ne15-30% munzvimbo dzekunze dzekunze.
Q: Ndinofanira kutsanangura sei NdFeB magineti corrosion dziviriro yekushandisa pasi pemvura?
A: Bare NdFeB inotanga kuora mumvura yemunyu mukati memaawa. Ni Kuti urambe uchinyura kana kuratidzwa mumvura yemunyu, wedzera epoxy overcoat inokwana 0.1mm gobvu. Mushonga wakanyanya kuvimbika wemushonga wemagineti usingapindi mvura munzvimbo yemugungwa uri kuvharira magineti musimbi isina tsvina kana imba yetitanium - hapana puratifomu inoiswa mumvura. Kana iyo dhizaini ichida kuti chiso chemagneti chiburitswe (kuti chiwedzere kuyerera pakusangana), iyo epoxy nzira ndeyekukanganisa kunonzwisisika; ongorora kuvimbika kwekupfeka usati waiswa mune chero mvura yemunyu.
