Ubwino wa zida zotenthetsera zotenthetsera ndi ma frequency osiyanasiyana a zida zotseketsa pafupipafupi

1) Njira yotenthetsera yapakati pafupipafupi

Ma frequency osiyanasiyana: wamba 1KHZ mpaka 20KHZ, mtengo wake ndi pafupifupi 8KHZ. Kutentha kwakuya ndi makulidwe ake ndi pafupifupi 3-10mm. Amagwiritsidwa ntchito kwambiri pakuwotcha, kutenthetsa, kutenthetsa, kuzimitsa ndi kuzimitsa zinthu zazikuluzikulu zogwirira ntchito, mazenera akulu akulu, mapaipi akulu okhala ndi mipanda yayikulu, magiya akulu a modulus ndi zida zina zogwirira ntchito, komanso kukhomerera kofiira, kukanikiza ndi kusungunula kocheperako. zitsulo. Dikirani.

2) Akupanga kutengerapo kutentha njira

Ma frequency osiyanasiyana: Wamba 20KHZ mpaka 40KHZ (chifukwa ma frequency amawu ndi 20HZ mpaka 20KHZ, motero amatchedwa super audio). Kutentha kwakuya ndi makulidwe, pafupifupi 2-3mm. Amagwiritsidwa ntchito kwambiri pakuwotcha kwambiri, kutenthetsa, kutenthetsa, kuzimitsa ndi kutenthetsa zapakati-m’mimba mwake, kutenthetsa, kuwotcherera, komanso kuphatikizira kotentha kwamapaipi okhala ndi mipanda yopyapyala, ndi kuzimitsa zida zapakatikati, ndi zina zambiri.

3) Njira yotenthetsera yotentha kwambiri

Ma frequency osiyanasiyana: wamba 30KHZ mpaka 100KHZ, omwe amagwiritsidwa ntchito kwambiri 40KHZ mpaka 80KHZ. Kutentha kwakuya, makulidwe, pafupifupi 1-2mm. Zida zozimitsira zotenthetsera pamwamba pazitsulo zimagwiritsidwa ntchito kwambiri potentha kwambiri, kuwombera kofiira, kukanikiza, kusungunula, kutenthetsa, kuzimitsa ndi kutentha, kuzimitsa pamwamba, kutentha kwapaipi ndi kuwotcherera, kusonkhana kotentha, kuzimitsa pinion, ndi zina zotero.

4) Njira yowotchera yopangira zida za UHF kuzimitsa

Mafupipafupi ndi okwera kwambiri, ma frequency osiyanasiyana: wamba 200KHZ kapena kupitilira apo, mpaka 1.1MHZ. Kutentha kwakuya ndi makulidwe ake ndi ochepa, pafupifupi 0.1-1mm. Amagwiritsidwa ntchito kwambiri kuzimitsa ndi kuwotcherera magawo ang’onoang’ono am’deralo kapena tizitsulo tating’onoting’ono, kuzimitsa zinthu zazing’ono, ndi zina zambiri.

Nthawi yomweyo, mitundu isanu iyi ya zida zotenthetsera zolowera zimakhala ndi zabwino zina. Onse amagwiritsa ntchito magetsi otenthetsera a IGBT, omwe ndi zida zowotchera kwambiri zopulumutsa mphamvu komanso zachilengedwe m’zaka za zana la 21.

①Zizindikiro zazikulu: kukula kochepa, mphamvu yayikulu, kutentha mwachangu, poyera pachimake, kugwiritsa ntchito mphamvu zochepa.

② Mkhalidwe wopulumutsa mphamvu: Poyerekeza ndi ma frequency apakati a thyristor akale, kutenthetsa kwapakati pa thyristor kumawononga pafupifupi madigiri 500 a magetsi pa tani iliyonse ya workpiece. Kampani yathu imagwiritsa ntchito mphamvu zapakati pafupipafupi pafupifupi madigiri 300. Toni iliyonse yowotchedwa imapulumutsa magetsi opitirira 200 kWh, omwe ndi 30% mphamvu zowonjezera mphamvu kuposa mayesero akale.

③ Zozungulira: Chipangizo chachikulu chimatengera gawo la IGBT, dera silimawongolera kukonzanso kwa mlatho wonse, kusefa kwa capacitor, inverter ya mlatho, ndi zotulutsa zingapo. Ndizosiyana kwambiri ndi ma frequency akale apakati pogwiritsa ntchito thyristor parallel resonance.

④Mfundo yopulumutsa mphamvu: Kuwongolera kosalamulirika, dera lowongolera limayatsidwa kwathunthu. High mphamvu factor, voteji-mtundu mndandanda resonance, etc., kudziwa kupulumutsa mphamvu ya zida izi. Mphamvu zodziwikiratu kutsatira luso zida, zida adzakhala basi kusintha mphamvu linanena bungwe malinga workpiece wanu. Kukula kwa zida kumatsimikiziridwa molingana ndi ntchito yotenthetsera. Kulemera kwa workpiece, kukwezera mphamvu, ndi kupepuka, kumachepetsa mphamvu.
