Jinsi ya kuchagua mzunguko wa sasa wakati tanuru inapokanzwa induction inapokanzwa bomba la chuma?
Jinsi ya kuchagua mzunguko wa sasa wakati tanuru inapokanzwa induction inapokanzwa bomba la chuma?
Induction inapokanzwa tanuru inapokanzwa bomba la chuma kwa ujumla ni kupitia joto, kwa hivyo, wakati wa kuchagua masafa, hali ya joto ya sasa joto D inapaswa kuwa kubwa kuliko unene wa ukuta wa bomba.
Jedwali 2 -. 8 inaonyesha bomba ya chuma ya kupokanzwa ya solenoid na mzunguko wa moja kwa moja wa chuma, na orodha ya Jedwali 2.9 (juu ya hatua ya Curie) inapokanzwa unene wa ukuta wa bomba la chuma ili kupata ufanisi bora zaidi wakati masafa anuwai.
Jedwali 2-8 Mzunguko bora wakati bomba la ond inapokanzwa bomba la chuma na bomba la chuma
