Kwimodyuli ye-inverter ye-medium-frequency spot welding, iimodyuli ze-IGBT (I-Insulated Gate Bipolar Transistor) zidlala indima ebalulekileyo ekulawuleni i-welding yangoku. Uhlengahlengiso olufanelekileyo lwangoku luyimfuneko ukuze kuqinisekiswe ukusebenza kwe-welding echanekileyo kunye nokusebenza kakuhle. Eli nqaku lijolise ekuxoxeni iindlela kunye neengqwalasela zokulungelelanisa okwangoku kwiimodyuli ze-IGBT ze-medium-frequency inverter spot welding machines.
- Imigaqo yoLawulo lwangoku: Iimodyuli ze-IGBT zinoxanduva lokulawula i-welding yangoku kwi-spot welding machines. Ezi modyuli zisebenza njengokutshintsha kwe-elektroniki, ukulawula ukuhamba kwangoku ngokusebenzisa i-welding circuit. Ikhoyo ngoku inokulungiswa ngokuguqula ububanzi be-pulse, i-pulse frequency, okanye i-amplitude yeempawu ze-IGBT.
- I-Pulse Width Adjustment: Enye indlela yokulawula okwangoku kukulungelelanisa ububanzi be-pulse yeempawu ze-IGBT. Ngokutshintsha ixesha le-ON state kwi-pulse nganye, umyinge wangoku ojikelezayo kwisiphaluka se-welding unokuguqulwa. Ukwandisa ububanzi be-pulse kubangela umyinge ophezulu wangoku, ngelixa ukuhla kunciphisa umyinge wangoku.
- Uhlengahlengiso lwe-Pulse Frequency: I-pulse frequency nayo ichaphazela i-welding current. Ngokulungelelanisa i-frequency apho ii-pulses zenziwa khona, ukuhamba ngokubanzi kwangoku kunokuguqulwa. Izandi ze-pulse eziphezulu zonyusa inani lee-pulses zangoku ezihanjiswayo kwiyunithi yexesha, okukhokelela kumndilili ophezulu wangoku. Ngokuchasene noko, ii-frequencies ezisezantsi zinciphisa umyinge wangoku.
- Ukulungiswa kwe-Amplitude: Kwezinye iimeko, i-welding current inokulungiswa ngokuguqula i-amplitude yeempawu ze-IGBT. Ngokunyusa okanye ukunciphisa inqanaba le-voltage yeempawu, i-current inokwandiswa ngokuhambelanayo okanye iyancipha. Nangona kunjalo, kubalulekile ukuqinisekisa ukuba uhlengahlengiso luhlala luphakathi kwemida ekhuselekileyo yokusebenza yeemodyuli ze-IGBT.
- Ukubeka iliso kwangoku kunye neNgxelo: Ukugcina ulawulo oluchanekileyo phezu kwe-welding current, kunenzuzo ukubandakanya iindlela zangoku zokubeka iliso kunye neempendulo. Ngokubeka iliso ngokuqhubekayo okwangoku ngexesha le-welding, izibonakaliso zempendulo zinokuveliswa ukulungelelanisa iimpawu ze-IGBT ngexesha langempela, ukuqinisekisa ukuhambelana nokuchanekileyo kwangoku.
- Ulungelelwaniso kunye neeNkqubo zokuQinisekisa: Ukulungelelaniswa kwexesha elithile kwiimodyuli ze-IGBT kunye neenkqubo zokulawula ezinxulumene nazo kubalulekile ukugcina ulungelelwaniso oluchanekileyo lwangoku. Iinkqubo zokulinganisa zingabandakanya ukuqinisekiswa kokuchaneka kweenzwa zangoku, ukulungiswa kweereferensi zombane, kunye nokuqinisekisa ukusebenza kweesekethe zolawulo. Ukulandela izikhokelo zomenzi kunye namaxesha acetyiswayo olungelelwaniso kubalulekile ukuqinisekisa ukusebenza kakuhle.
- Iingqwalasela zoKhuseleko: Xa uhlengahlengisa okwangoku kwiimodyuli ze-IGBT, kubalulekile ukunamathela kwiiprotocol zokhuseleko. Qinisekisa ukuba umatshini we-welding usekelwe ngokufanelekileyo, kwaye zonke izilungiso zenziwa ngabasebenzi abaqeqeshiweyo. Nika ingqalelo kwi-voltage kunye nemilinganiselo yangoku echazwe ngumenzi ukuthintela ukugqithiswa okanye ukonakalisa iimodyuli ze-IGBT.
Ukulungelelanisa okwangoku kwiimodyuli ze-IGBT ze-medium-frequency inverter spot welding machines yinkqubo ebalulekileyo efuna ukuqwalaselwa ngokucophelela kunye nokuthotyelwa kwezikhokelo zokhuseleko. Ngokuqonda imigaqo yolawulo lwangoku, kubandakanywa nobubanzi be-pulse, i-pulse frequency, kunye nohlengahlengiso lwe-amplitude, abavelisi banokufezekisa imisebenzi ye-welding echanekileyo kunye nokusebenzayo. Ulungelelwaniso lwarhoqo, ukubekwa kweliso kwangoku, kunye neendlela zokunika ingxelo ngakumbi ziphakamisa ukuchaneka nokuthembeka kwenkqubo yohlengahlengiso lwangoku. Ukuqeqeshwa okufanelekileyo kwabasebenzi ababandakanyekayo kuhlengahlengiso lwangoku kubalulekile ukuqinisekisa ukusebenza ngokukhuselekileyo kunye nokusebenza kakuhle komatshini we-welding.
