Izimpawu zikagesi Zesekethe yokushisela kumshini wokushisela we-Medium Frequency Inverter Spot

Isifunda sokushisela siyingxenye ebalulekile emshinini wokushisela we-medium frequency inverter spot welding, onesibopho sokuletha amandla kagesi adingekayo wenqubo yokushisela. Ukuqonda izici zikagesi zesifunda sokushisela kubalulekile ukuze kuqinisekiswe ukusebenza kahle nokuthembekile kwe-welding. Kulesi sihloko, sizohlola izici zikagesi zesekethe yokushisela emshinini wokushisela we-inverter ophakathi nendawo.

1. Ukunikezwa kwamandla: Ukunikezwa kwamandla kungumthombo oyinhloko wamandla kagesi kusekethe yokushisela. Emshinini wokushisela indawo ye-frequency inverter, amandla kagesi ngokuvamile aqukethe isilungisisi kanye ne-DC link capacitor. Isilungisisi siguqula amandla e-AC angenayo abe amandla e-DC, kuyilapho i-DC link capacitor ishelela i-voltage ripple, ihlinzeka ngevolthi ye-DC ezinzile yesekethe yokushisela.
2. I-Inverter: I-inverter iyingxenye ebalulekile eguqula amandla e-DC asuka esiphakeleni sikagesi abe amandla aphezulu e-AC. Iqukethe amadivaysi e-semiconductor yamandla, njenge-insulated gate bipolar transistors (IGBTs), ashintsha amandla kagesi e-DC kumafrikhwensi aphezulu (imvamisa ebangeni lama-kilohertz ambalwa). Isenzo sokushintsha se-inverter silawula i-welding current futhi sivumela ukulawulwa okunembile kwenqubo yokushisela.
3. I-Transformer: I-transformer kusekethe yokushisela inesibopho sokukhuphuka noma ukwehlisa i-voltage futhi idlulisele amandla kagesi kuma-electrode wokushisela. Iqukethe ama-winding ayisisekelo kanye nesesibili, ne-winding eyinhloko exhunywe ku-inverter kanye ne-secondary windings exhunywe kuma-electrode welding. Isilinganiso sokushintshwa kwe-transformer sinquma ukuguqulwa kwe-voltage futhi idlala indima ebalulekile ekuzuzeni umshini wokushisela ofunekayo kanye nokuphuma kwamandla.
4. Ama-Electrode Welding: Ama-electrode okushisela angamaphuzu okuxhumana lapho amandla kagesi edlula endaweni yokusebenza, enze i-weld. Ngokuvamile zenziwa ngezinto eziqhutshwayo, njengethusi, futhi zenzelwe ukumelana namandla amanje aphezulu kanye nokushisa okukhiqizwa phakathi nenqubo yokushisela. Izici zikagesi zama-electrode welding, okuhlanganisa ukumelana kwawo nendawo yokuxhumana, kuthinta ukusebenza kukagesi jikelele kwesekethe yokushisela.
5. Uhlelo Lokulawula: Isistimu yokulawula kumshini wokushisela we-medium frequency inverter spot futhi ilawula amapharamitha kagesi wesekethe yokushisela. Kuhlanganisa izinzwa, njengezinzwa zamanje nezamandla kagesi, ezinikeza impendulo kuyunithi yokulawula. Iyunithi yokulawula icubungula lolu lwazi futhi ilungise imvamisa yokushintsha kwe-inverter, umjikelezo wemisebenzi, neminye imingcele ukuze kugcinwe izimo zokushisela ezizinzile.

Izici zikagesi zesekethe yokushisela emshinini wokushisela i-medium frequency inverter spot zibalulekile ekufezeni imisebenzi yokushisela eyimpumelelo nephumelelayo. Ukuqonda indima yokunikezwa kwamandla, i-inverter, i-transformer, ama-electrode welding, kanye nohlelo lokulawula lwenza opharetha bakwazi ukuthuthukisa inqubo yokushisela nokuqinisekisa ukusebenza okuthembekile kukagesi. Ngokucabangela nokuphatha lezi zici zikagesi, abasebenzisi bangafinyelela izinga eliphezulu lokushisela ngokulawula okunembile phezu kwemingcele yokushisela.
