Uhlolo lweMagnetic Particle loKuphosa iziphene zangaPhakathi

Ukuhlolwa kwamasuntswana emagnethi yindlela yokufumanisa esebenzisa iimpawu zemathiriyeli ye-ferromagnetic (efana nentsimbi, intsimbi, icobalt, nickel, njl.njl.) ukuba yenziwe ngemagnethi. Xa iukuphosa isinyithiyenziwe nguzibuthe ngamandla ngumhlaba wemagnethi, ukuba kukho isiphene esithe gqolo kwicala lemagnethi kumphezulu okanye kufutshane nomphezulu wokujula, inxalenye yemigca yomhlaba wemagnethi iya kuphuphuma apha, yenze indawo evuzayo yamagnetic ukuvelisa iipali zemagnethi ezintsha. Ngeli xesha, umphezulu we-casting ugalelwe ngolwelo olumisiweyo lwamagnetic okanye ufefe ngepowder eyomileyo yamagnetic, kwaye amasuntswana omgubo wemagnethi abonisa umkhondo weziphene ngenxa yokutsalwa kweepali zemagnethi.

Xa uhlola amasuntswana omagnetic kwi-castings, indawo eyomeleleyo yamagnetic idla ngokuveliswa ngokunika amandla. Ngokweendlela ezahlukeneyo zamandla kunye neefomati zangoku, iindlela zemagneti zinokwahlulwa zibe yimagnetization ngokuthe ngqo kunye nemagneti engathanga ngqo, i-DC magnetization kunye ne-AC magnetization. Ngokwesalathiso apho umhlaba wemagnethi wenziwa kunye nendlela yokuvelisa umhlaba wemagnethi, kukho iindlela zemagneti ezinokuthi zohlulwe zibe yi-circumferential magnetization kunye ne-longitudinal magnetization, i-magnetization eqhubekayo kunye ne-residual magnetization. Kuhlolo lwangempela, i-Foundry inokukhetha iindlela ezahlukeneyo ze-AC kunye ne-DC ezihlanganisiweyo ze-magnetization ngokobungakanani bokuphosa, ukuhanjiswa kweziphene kunye nezinye izinto.

I-Magnetic powder yinto eyenza i-magnetic traces kwaye ibonisa iziphene, kwaye izinto zayo zihlala ziphezulu-i-valent iron oxide ene-permeability yamagnetic, i-remanence ephantsi kunye nokunyanzeliswa okuphantsi, njenge-ferric oxide kunye ne-ferric oxide. Ubungakanani besuntswana lomgubo wemagnethi lukhethwa ukuba lube ngu-80 - 300 μm kwindlela yokuvavanya ngomgubo owomileyo. Ukuhlolwa okumanzi kunye ne-fluorescent, ubungakanani be-particle ye-powder magnetic bunokuba ngcono. Iziphene ezincinci zokuphosa kufuneka zikhethe umgubo ocolekileyo wemagnethi. Ubume bomgubo wemagnethi kufuneka ukuba ube ngumgubo wemagnethi ongqukuva, kwaye emva koko uthelekiswe nenxalenye ethile yomgubo wemagnethi.

Ukumiswa komgubo wemagnethi ngumxube womgubo wemagnethi kunye nokusasazwa kwinqanaba elithile. Iqhezu lomthamo wepowder magnetic eqhelekileyo yi-1.3% - 3.0%, kunye neqhekeza levolumu ye-fluorescent powder magnetic yi-0.1% - 0.3%. Ulwelo lwe-dispersion lunokukhethwa kwi-ejenti yamanzi, i-kerosene kunye nomxube we-kerosene kunye neoli ye-transformer, enekhono lokuthintela ukugqwala, ukumanzisa kunye nokuhlambalaza.

 

Iimpawu kunye nobungakanani bokusetyenziswa kokuhlolwa kwesuntswana lamagnetic:

1. Ukuhlolwa kwamasuntswana emagnethi kunobona buntununtunu buphezulu bokubona umphezulu okanye iziphene ezikufutshane nomphezulu wokusaswa, kodwa ubuntununtunu buyehla ngokukhawuleza ngokunyuka kobunzulu besiphene.

2. Le ndlela yokufumanisa isebenza kuphela ekubhaqweni kwezixhobo ze-ferromagnetic, kodwa ayinakusetyenziselwa ukuphoswa kwe-non-magnetic njenge-austenitic stainless steels.

3. Isixhobo sokuhlola i-particle magnetic silula, kwaye isixhobo esiphathwayo silula ukusebenza kwisayithi.

4. Ukuhlolwa kwesuntswana lemagnethi kuneemfuno eziphezulu kuburhabaxa bendawo yokuphosa.

5. Emva kokuhlolwa kokuphoswa, kuyimfuneko ukucoca umphezulu kwaye ususe i-powder magnetic eseleyo ngexesha. Ukuba kuyimfuneko, unyango lwe-demagnetization luyafuneka.
