摘要
基于低碳钢比硅钢片资源丰富,且价格低廉,为降低水泵行业微型电泵电机定子用材料成本,进行了退火蓝化低碳钢替代硅钢片的试验.分析了低碳钢的退火蓝化机理,研制了一套低碳钢定子材料的退火蓝化工艺方案,并将蓝化后的低碳钢定子在电泵电机中进行了试验验证,对使用低碳钢材料与硅钢片材料的电泵电机的空载电流、满载电流、效率、功率因数和温升等主要技术指标进行了对比分析.试验结果表明,退火蓝化工艺能显著提高低碳钢的电磁性能,使其达到硅钢片的技术指标,从而满足电泵电机的性能要求,验证了将低碳钢经退火蓝化后替代硅钢片用作微型电泵电机定子材料的可行性.
Compared to silicon steel sheet, low-carbon steel has its advantages of rich resources and low price. In order to reduce cost of micro eleetromotor of micro electric pump used in pump industry, an ex- perimental study of the application of low-carbon steel instead of silicon steel sheet on the electromotor of micro electric pump was carried out. The mechanism of annealing and blueing was analyzed. A process of annealing and blueing treatment for stator of low-carbon steel was designed. In order to make a comparative analysis of the main technical specifications such as no-load and full-load current, efficiency, tem- perature rise, and power factor of electromotor between low-carbon steel stator and silicon steel stator, a performance test of electromotor of electric pump installed with the stator of low-carbon steel was conduc- ted. The experimental results show that the electromagnetic properties of low-carbon steel sheet after an- nealing and blueing treatment reach the technical specifications of silicon steel, so it is workable to be taken as alternative material for silicon steel sheet for stator of electromotor of motor pump.
