电机高效再制造在某石化厂循环水泵中的应用

High-Efficient Remanufacturing Motor for Applications of Circulating Pump Energy-Saving in Petrochemical Plant

对于负荷比较稳定且运行时间较长而又无流量调节的循环水泵电机系统来说,使用高效电机简单替换并不能直观体现节能效果。在对某石化公司循环水泵电机的运行参数进行详细测试并分析后,采用电机高效再制造技术,有针对性地保留了原电机转子部分,电机定子改为新设计高效定子铁心。再制造电机实验室测试验证达到设计要求,并应用于原循环水泵系统,在前后工况一致下进行实测,获得了较好的节能效果和较短的投资回收期。

For the circulating pump motor system, which load is relatively stable and longer running time but no flow regulator, the use of high efficiency motor replace the simple motor can not intuitively reflect effect of energy saving. Test and analyze the operating parameters for the circulation pump motor in a petrochemical plant, adopting high-efficient remanufacturing technology, including retain parts of original rotor, replace by a new design high- efficient stator core. The test of manufacturing motor laboratory verifies it, which meet the design requirements. When applied to the original circulating pump system and measured under the same conditions, the systems get a good energy saving effect and short payback period.
