Emishinini yokushisela indawo ye-inverter enemvamisa emaphakathi, amamojula e-IGBT (Insulated Gate Bipolar Transistor) adlala indima ebalulekile ekulawuleni amandla okushisela.Ukulungiswa okufanele kwamanje kubalulekile ukuze kuqinisekiswe ukusebenza kwe-welding okunembile nokusebenza kahle.Lesi sihloko sihlose ukuxoxa ngezindlela nokucatshangelwa kokulungisa okwamanje kumamojula we-IGBT wemishini yokushisela i-medium-frequency inverter spot welding.
- Izimiso Zamanje Zokulawula: Amamojula e-IGBT anomthwalo wemfanelo wokulawula amandla okushisela emishinini yokushisela.Lawa mamojula asebenza njengokushintshwa kwe-elekthronikhi, alawula ukugeleza kwamanje ngesekethe yokushisela.Okwamanje kungalungiswa ngokushintsha ububanzi be-pulse, imvamisa ye-pulse, noma i-amplitude yamasignali e-IGBT.
- Ukulungiswa Kobubanzi Be-Pulse: Enye indlela yokulawula okwamanje ngokulungisa ububanzi be-pulse yamasignali e-IGBT.Ngokushintsha ubude besimo se-ON ku-pulse ngayinye, isilinganiso samanje esigeleza kumjikelezo we-welding singashintshwa.Ukwenyusa ububanzi be-pulse kuphumela esilinganisweni esiphezulu samanje, kuyilapho ukuwehlisa kunciphisa isilinganiso samanje.
- I-Pulse Frequency Adjustment: I-pulse frequency nayo ithinta i-welding current.Ngokulungisa imvamisa lapho ama-pulses akhiqizwa khona, ukugeleza kwamanje sekukonke kungashintshwa.Amaza okushaya kwenhliziyo aphezulu akhulisa inani lama-pulses amanje alethwa ngeyunithi yesikhathi, okuholela ekukhuphukeni kwesilinganiso samanje.Ngokuphambene, amaza aphansi anciphisa isilinganiso samanje.
- Ukulungiswa Kwe-Amplitude: Kwezinye izimo, i-welding current ingalungiswa ngokushintsha i-amplitude yezimpawu ze-IGBT.Ngokwandisa noma ukwehlisa izinga le-voltage yamasignali, yamanje ingakhushulwa ngokuhambisanayo noma yehliswe.Nokho, kubalulekile ukuqinisekisa ukuthi ukulungiswa kuhlala kungaphakathi kwemikhawulo yokusebenza ephephile yamamojula e-IGBT.
- Ukuqapha Kwamanje Nempendulo: Ukugcina ukulawula okunembile phezu kwamandla okushisela, kunenzuzo ukufaka izindlela zamanje zokuqapha kanye nempendulo.Ngokuqhubeka nokuqapha okwamanje okwangempela ngesikhathi sokushisela, amasignali empendulo angenziwa ukuze kulungiswe amasignali e-IGBT ngesikhathi sangempela, kuqinisekiswe ukuphuma kwamanje okungaguquki nokunembile.
- Izinqubo Zokulinganisa Nokulinganisa: Ukulinganisa ngezikhathi ezithile amamojula e-IGBT kanye nezinhlelo zokulawula ezihambisanayo kubalulekile ukuze kugcinwe ukulungiswa okunembile kwamanje.Izinqubo zokulinganisa zingase zibandakanye ukuqinisekisa ukunemba kwezinzwa zamanje, ukulungisa amareferensi kagesi, nokuqinisekisa ukusebenza kwamasekhethi okulawula.Ukulandela imihlahlandlela yomkhiqizi nezikhawu zokulinganisa ezinconyiwe kubalulekile ukuze kuqinisekiswe ukusebenza kahle.
- Ukucatshangelwa Kokuphepha: Lapho ulungisa okwamanje kumamojula e-IGBT, kubalulekile ukuthobela izimiso zokuphepha.Qinisekisa ukuthi umshini wokushisela usekelwe kahle, futhi zonke izinguquko zenziwa izisebenzi eziqeqeshiwe.Naka amandla kagesi kanye nezilinganiso zamanje ezicaciswe umenzi ukuze uvimbele ukugcwala noma ukulimaza amamojula e-IGBT.
Ukulungiswa kwamanje kumamojula we-IGBT wemishini yokushisela indawo ye-inverter ye-medium-frequency kuyinqubo ebalulekile edinga ukucatshangelwa ngokucophelela nokuhambisana neziqondiso zokuphepha.Ngokuqonda izimiso zokulawula kwamanje, okuhlanganisa ububanzi be-pulse, imvamisa ye-pulse, nokulungiswa kwe-amplitude, abakhiqizi bangakwazi ukufeza imisebenzi yokushisela enembile futhi ephumelelayo.Ukulinganisa okuvamile, ukuqapha kwamanje, kanye nezindlela zempendulo zithuthukisa ukunemba nokuthembeka kwenqubo yamanje yokulungisa.Ukuqeqeshwa okufanele kwabasebenzi abathintekayo ekulungiseni kwamanje kubalulekile ukuze kuqinisekiswe ukusebenza okuphephile nokusebenza kahle komshini wokushisela.
