Emkhakheni wezimboni wesimanje, imishini yokushisela indawo ephakathi{0}}ye-inverter inverter isiphenduke into ebaluleke kakhulu ezimbonini ezifana nezezimoto, izinto zasendlini, nezinto zikagesi. Ngenxa yokusebenza kahle kwayo okuphezulu,{2}}ukonga amandla, kanye nezici ezihambisana nemvelo, le mishini yokushisela isetshenziswa kakhulu ezinqubweni zokukhiqiza imikhiqizo ehlukahlukene.
Uma usebenzisa-i-inverter yefrikhwensi emaphakathiimishini yokushisela amabala, ukwakheka nobukhulu bamaqhuqhuva omsebenzi abalulekile njengoba athinta ngqo ikhwalithi yokushisela kanye nokusebenza kahle kokukhiqiza kukonke. Ngokulawula kahle usayizi nokuma kwamaqhuqhuva, amandla okushisela angathuthukiswa, amaphutha ancishiswe, futhi izindleko zokukhiqiza zenziwe ngcono.
Ukumatanisa Usayizi wamaNodule kanye Nokuqina Kwempahla
Imishini yokushisela indawo-ephakathi nemvamisa inezidingo eziqinile zobude be-nodule yocezu lokusebenza, ngokuvamile izikhathi ezingu-1.2 kuya ku-1.5 zogqinsi lwengqikithi yento. Isibonelo, lapho ushisela amashidi ensimbi engu-1.5mm, ukuphakama kwe-nodule okunconyiwe kuphakathi kuka-1.8mm no-2.2mm. Uma ubude be-nodule bungahlangabezani nezinga, kungase kubangele ukwehla kwekhwalithi yokushisela:
- I-Nodule Ephansi: I-nodule ephansi izobangela ukusabalala kwamanje, okuholela ekungeneni kwamandla okushisela, okungase kuthinte ukuzinza nokuthembeka{0}}kwesikhathi eside kwe-weld.
- I-Nodule ephezulu: I-nodule ephakeme kakhulu ingaholela ekugxiliseni kwamanje okweqile, okungase kubangele ukusakazeka noma ukusha{0}}kudlule, kuthinte kabi ukunemba kwe-weld.
Lesi sici sisho ukuthi ubukhulu be-nodule kufanele bufaniswe ngokunembile nobukhulu bezinto ezibonakalayo ukuze kuqinisekiswe ngisho nokusabalalisa ukushisa nokucindezela phakathi nenqubo yokushisela.
I-Nodule Diameter kanye ne-Electrode Pressure Coordination
Ekushiseleni okusebenzayo, ububanzi be-nodule budinga ukuxhunyaniswa nokucindezela kwe-electrode yomshini wokushisela indawo-evamile. Ngokusekelwe{2}kudatha yangempela yomhlaba, amaqhuqhuva amakhulu adinga umfutho ophakeme we-electrode ukuze kuqinisekiswe ikhwalithi yokushisela.
Isibonelo, lapho ushisela i-nodule enobubanzi obungu-5mm, ingcindezi ye-electrode kufanele ilawulwe phakathi kuka-70,000N no-75,000N. Lolu hlu lokucindezela luqinisekisa ukuthintana okuzinzile phakathi nenqubo yokushisela futhi kuvimbela ukusatshalaliswa okungalingani kwamanje kanye nokukhubazeka kwe-weld.
Umsebenzi wokulungisa umfutho we-electrode emishinini yokushisela indawo ephakathi-yemvamisa wenza lokhu kuhlotshaniswa phakathi kwengcindezi nobubanzi be-nodule kwenzeke, kuqinisekiswe nokusabalaliswa kwendawo encibilikisiwe futhi kuthuthukise amandla okuhlangana okushisela.
Ukuma kweNodule kanye Nokujwayela Kokukhipha Kwamanje
I-Inverter-emaphakathiimishini yokushisela amabalaafakwe amandla okulawula amanje anamandla, nesilinganiso esiphezulu-sesekhethi samanje esingafika ku-60KA. Ngakho-ke, ukwakheka kwe-nodule shape kubalulekile. Umumo wejiyomethri ojwayelekile njengama-semi-ayisiyingi noma ama-conical nodules asiza ukugxila kwamanje futhi ehlise ukumosheka kwamandla. Ngokuphambene, ama-nodule amise ngendlela engavamile angaholela ekusabalaliseni kwamanje okungalingani, kuthinte kabi ikhwalithi yokushisela.
Ngokulungiselela ukuma kwe-nodule, okukhiphayo kwamanje okusebenza kahle kakhudlwana kungaqinisekiswa, kuthuthukiswe ikhwalithi yokushisela, kuncishiswe ukusetshenziswa kwamandla kwemishini, nokwehlisa izindleko zokukhiqiza.
Umthelela we-Electrode Wear ku-Nodule Dimensions
Ngokuhamba kwesikhathi, ama-electrode emishini yokushisela amabala aphakathi{0}}emvamisa azowohloka kancane kancane, okuholela endaweni yokuxhumana enwetshiwe, okuthinta ukuzinza kobukhulu bamaqhuqhuva.
Ukugqoka okuqhubekayo kungaholela kwikhwalithi ye-welding engazinzile, ngakho-ke kuyadingeka ukugaya ngezikhathi ezithile ama-electrode ukuze kugcinwe ukuhlanzeka kwendawo kanye nendawo yokuxhumana.
Ukwengeza, ukusebenzisa uhlelo lokupholisa kunganciphisa ngempumelelo isivinini sokugqoka i-electrode, kunwebe impilo yesevisi ye-electrode. Ukuhlolwa njalo nokugcinwa kwama-electrode kubalulekile ukuze kuqinisekiswe ukushisela nokuvumelana nokwenza ngcono ukukhiqiza.
Isiphetho
Izidingo zamanodule ocezu lokusebenza emishinini yokushisela indawo ephakathi-ye-frequency inverter azilungisiwe kodwa zidinga ukulungiswa ngokushintshashintshayo ngokusekelwe ezintweni ezibonakalayo, amapharamitha wemishini, kanye nezidingo zenqubo. Ngokulawula ngokunembile ubude, ububanzi, ukuma kwe-nodule, nokucindezela kwe-electrode, ikhwalithi yokushisela ingathuthukiswa kakhulu ngenkathi inweba impilo yesevisi yemishini.
Ekusebenzeni okungokoqobo, kunconywa ukusebenzisa{0}}imisebenzi yokuqapha isikhathi sangempela-somshini wokushisela indawo yefrikhwensi ukuze uqhubeke nokuthuthukisa izilungiselelo zepharamitha, uqinisekise ukukhiqizwa okuphumelelayo nezinzile.
Ngaphezu kwalokho, njengento -esebenza kahle yokushisela amandla, -imvamisa umshini wokushisela indawo akugcini nje ngokuthuthukisa ikhwalithi yokushisela kodwa futhi kunciphisa izindleko zokukhiqiza zamabhizinisi, okwenza kube idivayisi ebalulekile ekuzuzeni ukukhiqizwa okuhlakaniphile.
