Iimpawu zoMbane zeSekethe yeWelding kumatshini wokuwelda we-Inverter Frequency Spot Spot

I-welding circuit iyingxenye ebalulekileyo kwi-medium frequency inverter spot welding machine, enoxanduva lokuhambisa amandla ombane ayimfuneko kwinkqubo ye-welding. Ukuqonda iimpawu zombane zesekethe ye-welding kubalulekile ekuqinisekiseni ukusebenza ngokufanelekileyo kunye nokuthembeka kwe-welding. Kweli nqaku, siza kuphonononga iimpawu zombane zesekethe ye-welding kumatshini wokuwelda we-inverter ophakathi.

1. Unikezelo lwamandla: Umbane ngowona mthombo wamandla ombane kwisekethe ye-welding. Kumatshini wokuwelda indawo yokutshintsha amaza aphakathi, unikezelo lwamandla lubandakanya isilungisi kunye ne-DC link capacitor. I-rectifier iguqula amandla angenayo e-AC kumandla e-DC, ngelixa i-DC link capacitor igudisa i-voltage ripple, inika i-voltage ye-DC ezinzileyo yesekethe ye-welding.
2. I-Inverter: I-inverter licandelo elibalulekileyo eliguqula amandla e-DC ukusuka kunikezelo lwamandla ukuya kumandla aphezulu we-AC. Iqulathe izixhobo zesemiconductor yamandla, ezifana nesango eligqunyiweyo le-bipolar transistors (IGBTs), ezitshintsha amandla ombane e-DC kwi-frequency ephezulu (ngokuqhelekileyo kuluhlu lweekhilohertz ezininzi). Isenzo sokutshintsha kwe-inverter silawula i-welding current kwaye ivumela ukulawulwa ngokuchanekileyo kwenkqubo ye-welding.
3. I-Transformer: I-transformer kwi-welding circuit inoxanduva lokunyuka okanye ukuhla kwi-voltage kunye nokudlulisa amandla ombane kwii-electrodes ze-welding. Iqukethe i-winding ephambili kunye neyesibini, kunye ne-primary winding edibeneyo kwi-inverter kunye ne-second winding edibeneyo kwi-electrodes ye-welding. Umlinganiselo wokujika we-transformer umisela ukuguqulwa kwamandla ombane kwaye udlala indima ebalulekileyo ekuphumezeni i-welding efunekayo yangoku kunye nemveliso yamandla.
4. I-Welding Electrodes: I-electrodes ye-welding ngamanqaku oqhagamshelwano apho umbane wombane udlula kwi-workpiece, ukudala i-weld. Ngokuqhelekileyo zenziwe ngezinto eziphathekayo, ezifana nobhedu, kwaye zenzelwe ukujamelana nokuphezulu kwangoku kunye nokushisa okwenziwa ngexesha lenkqubo ye-welding. Iimpawu zombane ze-electrodes welding, kubandakanywa ukuchasana kwazo kunye nommandla woqhagamshelwano, zichaphazela ukusebenza kombane jikelele kwisiphaluka se-welding.
5. Inkqubo yokulawula: Inkqubo yolawulo kwi-medium frequency inverter spot welding machine monitors kwaye ilawula iiparamitha zombane zesekethe ye-welding. Ibandakanya abenzi boluvo, njengangoku kunye ne-voltage sensors, enika ingxelo kwiyunithi yokulawula. Iyunithi yokulawula iqhuba olu lwazi kwaye ilungelelanise i-inverter's switching frequency, umjikelezo womsebenzi, kunye nezinye iiparitha ukugcina iimeko ezizinzileyo ze-welding.

Iimpawu zombane zesekethe ye-welding kumatshini we-welding we-welding ophakathi i-frequency inverter spot ibalulekile ekufezekiseni impumelelo kunye nokusebenza kakuhle kwe-welding. Ukuqonda indima yonikezelo lwamandla, i-inverter, i-transformer, i-electrodes ye-welding, kunye nenkqubo yokulawula ivumela abaqhubi ukuba basebenzise inkqubo ye-welding kwaye baqinisekise ukusebenza kombane okuthembekileyo. Ngokuqwalasela kunye nokulawula ezi mpawu zombane, abasebenzisi banokufikelela kwi-welds ephezulu kunye nokulawula okuchanekileyo kwiiparameters ze-welding.
