摘要
通过系统特性分析 ,对焦炉无烟装煤工艺中高压氨水泵运用变频技术进行改造 ,并采用闭环调节 ,取得了较好的实际效果。
On the basis of analysis of system characteristics, frequency conversion technique is adopted to transform an aqueous ammonia pump of high pressure in coal charging process without dust of coke oven, and the closed loop control is used, which have gained better effects.
