Ukuvama nokusetshenziswa kwezikhathi zokushisisa ezahlukene zemishini yokucisha imvamisa ephezulu
Ukuvama kanye nezikhathi zokusetshenziswa kwezindlela ezihlukene zokufudumeza imishini yokuqeda imvamisa ephezulu
1) Ibanga lefrikhwensi yendlela yokushisa yokungeniswa kwefrikhwensi ephezulu: evamile 40KHZ ukuya ku-200KHZ, evame ukusetshenziswa 40KHZ ukuya ku-80KHZ. Ukujula kokushisa nokuqina kumayelana ne-1-2mm. Imishini yokuqinisa indawo yokushisa yokungeniswa isetshenziswa kakhulu ekushiseni okujulile, ukubhoboza okubomvu, ukubumba, ukuthungatha, ukufudumeza, ukucisha nokufudumeza, ukucisha indawo, ukufudumeza kanye nokushisela amapayipi anobubanzi obuphakathi, ukuhlanganisa okushisayo, ukucisha iphinikhodi, njll. kwamapayipi amancane okusebenza.
2) Indlela yokushisa yokungenisa imvamisa ephezulu kakhulu
I-frequency iphakeme kakhulu, i-frequency range: ngaphezu kuka-200KHZ, ifika kumashumi e-MHZ. Ukujula kokushisa nokuqina kuncane kakhulu, cishe ku-0.1-1mm. Isetshenziselwa kakhulu ukucisha kanye nokushisela izingxenye zasendaweni ezincane kakhulu noma imigoqo emincane kakhulu, kanye nokucisha okungaphezulu kwama-workpiece amancane.
Ngesikhathi esifanayo, lezi zinhlobo ezinhlanu zemishini yokushisa yokungeniswa zinezinzuzo ezithile. Bonke basebenzisa izinsiza zamandla zokushisisa ze-IGBT. Ziyizinto zokushisa ezingeniswayo ezonga kakhulu futhi ezinobungani nemvelo ekhulwini lama-21.
3) Indlela yokushisa yokungeniswa kwefrikhwensi ephezulu yomsindo
Ibanga lefrikhwensi: okuvamile okungu-20KHZ kuya ku-40KHZ (ngoba imvamisa yomsindo ingu-20HZ ukuya ku-20KHZ, ngakho ibizwa ngokuthi umsindo omkhulu). Ukujula kokushisa nokuqina kucishe kube ngu-2-3mm. Isetshenziselwa kakhulu ukufudumeza okujulile, ukuthungatha, ukufudumeza, ukucisha kanye nokufudumeza kwezinto zokusebenza ezinobubanzi obuphakathi, ukufudumeza, ukushisela, ukuhlanganiswa okushisayo kwamapayipi anezindonga ezincane ezinobubanzi obukhulu, nokucisha amagiya amaphakathi.
4) Indlela yokushisa yokungenisa imvamisa ephansi
Ifrikhwensi ephansi kakhulu, ububanzi befrikhwensi: imvamisa yamandla (50HZ) ukuya cishe ku-1KHZ, ifrikhwensi evame ukusetshenziswa kakhulu imvamisa yamandla. Ukujula kokushisa okuhlobene kujulile, futhi ubukhulu bokushisa bukhulu kakhulu, cishe 10-20mm;. Ikakhulukazi isetshenziselwa ukufudumeza konke, ukuthungatha, ukufudumeza kanye nokucisha izinto zokusebenza ezinkulu. Imishini yokushisela imvamisa ephezulu
5) Ibanga lefrikhwensi yendlela yokushisa yokungeniswa kwefrikhwensi emaphakathi: okuvamile 1KHZ ukuya ku-20KHZ, inani elijwayelekile licishe libe ngu-8KHZ. Ukujula kokushisa nokuqina kumayelana no-3-10mm. Isetshenziselwa kakhulu ukufudumeza, ukuthungatha, ukufudumeza, ukufudumeza kanye nokucisha indawo yokusebenza emikhulu, amashafu amakhulu obubanzi, amapayipi amakhulu odonga oluwugqinsi, amagiya amakhulu e-modulus, kanye nokubhoboza okubomvu nokudambisa imigoqo emincane yobubanzi.
Isizukulwane esisha semishini yokucisha imvamisa ephezulu sithuthukisa kakhulu ukusebenza kahle kokukhiqiza. Izinzuzo zibonakaliswa ngokuyinhloko kumaphuzu alandelayo:
① Izici eziyinhloko: usayizi omncane, amandla aphezulu, ukushisisa okusheshayo, umgogodla obonakalayo, ukusetshenziswa kwamandla okuphansi.
② Izici zesifunda: Idivayisi eyinhloko yamukela imojula ye-IGBT, isifunda asilawuli ukulungiswa okugcwele kwebhuloho, ukuhlunga kwe-capacitor, inverter yebhuloho, ukuphuma kwe-resonance yochungechunge. Ihluke kakhulu kumafrikhwensi aphakathi nendawo esebenzisa i-thyristor parallel resonance.
③Isimo sokonga amandla: Uma kuqhathaniswa nefrikhwensi yamaphakathi ye-thyristor yakudala, i-thyristor intermediate frequency heat sebenzisa cishe amadigri angu-470 ngethani ngalinye le-workpiece.
④Umgomo wokonga amandla: Ukulungisa okungalawuleki, kanye nesekhethi yesilungisi isebenza ngokugcwele. Isici samandla aphezulu, i-voltage yochungechunge lwe-resonance, njll., inquma ukonga amandla okukhulu kwalesi sisetshenziswa.
