Iyini i-induction furnace imishini yokuhlunga emithathu?

1. Isithando somlilo sikagesi esingeniswayo ‍ Izisetshenziswa zokuhlunga ezintathu zikala izinga lokushisa lezikhala eziphuma embobeni yokukhipha isithando somlilo esiphakathi nendawo ngethemomitha ye-infrared, futhi iphakela lesi siginali yokushisa ohlelweni lokulawula isithando somlilo esiphakathi nendawo kanye nohlelo lokulawula lwe-PLC. ngokusebenzisa uhlelo lokulawula izinga lokushisa, ukuze Lungisa izinga lokushisa lokushisa futhi ulawule izinga lokushisa ukuze uhlukanise isilinda ukuze kuzuzwe izidingo zenqubo efanelekayo. Izinga lokushisa elingenalutho liyadlula, izinga lokushisa elingenalutho lokushisisa liphansi kunezidingo zenqubo kanye nezinga lokushisa elingenalutho elingaphezu kwezidingo zenqubo faka ifreyimu yempahla yokushisa ephansi kanye nohlaka lwempahla yokushisa ephezulu ngokulandelanayo, ukuze kubonakale ukuhlunga kathathu kwesithando somlilo.

1. Indlela yokuzenzakalela yokuhlunga yesithando somlilo sokungeniswa izinto ezintathu zokuhlunga iqukethe iswishi ye-photoelectric, isitholi sezinga lokushisa le-infrared, isilawuli (SR3) kanye ne-PLC. Ngemuva kokuthi inkinobho ye-photoelectric ithole ukukhishwa, ithumela lesi siginali ku-PLC. Ngemva kokuba i-PLC ithole isignali yokukhipha, ithumela umyalo ukuze ithole ukuthi ingabe kukhona isignali ye-alamu yomkhawulo ophezulu naphansi wesilawuli. Uma kukhona lesi siginali, izokhipha umyalelo wokwenza isilinda esiphusha esingafanele sinyakaze; uma ingekho isignali enjalo, izokhipha umyalelo wokwenza isilinda esiphusha esifanelekayo sinyakaze. Isignali yomyalo efanelekayo noma engafaneleki lapha isignali ebambezelekile ethunyelwe ngemva kokutholwa kwesignali yokukhipha, inhloso ukugwema isilinda sokuhlunga okubangelwa ukungazinzi komtshina wokushisa we-infrared kanye nomlawuli esigabeni sokuqala sokulinganisa izinga lokushisa isenzo esiyiphutha. Ubude besikhathi sokulibaziseka bulungiswa isilungiselelo se-analog potentiometer 0 ku-PLC (uhlu lokusetha lwale potentiometer luyimizuzwana engu-0—20). Ukuthi izinga lokushisa lomshini wokusebenza lifanelekile noma cha kuqedwa yisilawuli (SR3), futhi imikhawulo engaphezulu nephansi yebanga lokushisa elifanelekayo kufanele isethwe njengama-alamu omkhawulo aphezulu naphansi wesilawuli. Isibonelo: Uma izinga lokushisa lomshini wokusebenza lithathwa njengelijwayelekile ebangeni lika-1100°C—1200°C, i-alamu yomkhawulo ophezulu wesilawuli kufanele isethelwe ku-1200°C, futhi i-alamu yomkhawulo ophansi kufanele isethelwe ku-1100°C. Izinto zokusebenza ezingaphakathi kwalolu banga lokushisa ziphushwa kumzila wesitimela ofanelekayo we-workpiece cylinder, futhi izinto zokusebenza ezingekho ngaphakathi kwalolu banga lokushisa ziphushelwa kumzila wesiqephu sokusebenza esingafanelekile yi-pusher cylinder engafanelekile, ukuze kuqedelwe ukuhlunga okuzenzakalelayo. ukusunduza nokukhipha isithando somlilo esiphakathi. .
