Ụzọ demagnetization na ọrụ nke 900kw Diesel Generator

900kw mmanụ dizel generator, dị ka a igwe na-ebu ike dị elu , nwere ike zuru oke na ike siri ike.N'otu oge ahụ, dị ka onye na-emepụta mmanụ dizel, ọ nwere njirimara nke ọrụ dị mfe na nhazi dị mma.Ego ole ka ị maara maka usoro demagnetization na ọrụ nke generator diesel 900kw?

Igwe mmanụ dizel 900kw na-aghọ ihe na-agwụ ike.
