Imigaqo yoLawulo loBubushushu be-Induction Heating Furnace eIndiya

Umgaqo wokulawula ubushushu baseIndiya ukufudumeza iziko iboniswe kumfanekiso oqhotyoshelweyo. Le bhodi ibandakanya iinxalenye ezimbini zokulawula ubushushu, kwaye igalelo lokulawula ubushushu lithatha umqondiso we-0-20mA oqhelekileyo wangoku. Umqondiso wangoku uthathwa njengophawu lwe-voltage nge-R52, kwaye emva koko ubalwa kunye ne-W ye-terminal voltage ehambayo, kwaye emva koko ikhuliswe kwaye ikhutshwe yibhloko edibeneyo ye-U1D. Ubuninzi be-voltage ephumayo buchongwa kwinqanaba le-W ehambayo ye-terminal enokwenzeka kwisiphaluka sokulawula ubushushu. Igalelo lokulawula ubushushu ngu-0 ~ I-20mA yesiginali yangoku iguqulwa ibe ngumqondiso we-voltage nge-R52 kwaye ithelekiswa nenqanaba le-potentiometer yangaphandle ehambayo enokwenzeka. Umahluko we-voltage phakathi kwezi zibini ukhuliswe yi-U1D ukutshintsha i-voltage ephumayo. Uluhlu lotshintsho lumiselwa yi-R54 kunye ne-R51, ngokubanzi kwi-Ibekwe malunga namaxesha ali-10 xa ushiya umzi-mveliso. Seta umahluko wombane phakathi kwe-UR52 kunye ne-UW2 ibe yi-0.1V, kwaye amandla ombane kwi-terminal ephumayo ye-U1D kufuneka abe malunga ne-1V. Kumsebenzi oqhelekileyo, isiphumo esinikiweyo se-BH sinamandla aphantsi, emva kokuba ulawulo lweqondo lokushisa luvuliwe, umphumo unamandla aphezulu, kwaye umbane owenziwe ngamandla ombane ophakathi uphuhlisa ukuya kwinqanaba eliphantsi. Ukufezekisa injongo yokulawula ubushushu. Inqanaba lobushushu limiselwa kwinqanaba le-W dynamic terminal potential. Ngokuqhelekileyo, ixabiso le-W lesalathisi sokushisa linokulungiswa ngokufanelekileyo.
