摘要
目前石油化工企业仍在大量使用交流异步电动机,其中多数还处在非经济运行状态,造成电能的大量浪费.各石化企业推广的许多节能降耗措施,在节能的同时未能降低设备磨损率,无法延长设备寿命.提出了利用变频调速器控制电机和机泵的转速达到降低电能消耗,减少生产成本的途径.
At present,petrochemical corporation is using AC asynchronous electromotor,most of them are in the state of non-economical operation,which result in large waste of power.Many measures for saving power and reducing waste which is generalized by every petrochemical corporation don＇t reduce the rate of equipments＇ abrasion and prolong the life of the equipments while it is saving power.This paper discusses how to take advantage of electromotor controlled by frequency control device pump to achieve the way of reducing power waste and cost.
