智能电表在密炼机炼胶中的应用

Application of intelligent electric meter in internal mixer rubber mixing

在密炼机的生产中,生产厂家需要运行人员,每天对生产中密炼机的电能表进行所用的电能进行手工抄录,并结合对比每天密炼机的产量的用电量,单车次炼胶的用电量都是否一致,并进行分析,从而分析高设备的运行情况。然而人工抄表效率低,生产线越多,每天的人工耗时就越长,通常耗时在一小时以上,而且手工抄录数据,精度较差。通过使用智能电表,解决了人工抄表效率低,及人工抄表无法抄读出电表内部小时段分项数据的问题,并配合密炼机控制系统SIMATIC S7-1500 PLC进行PN通讯,并快速准确的将电能表的信息传给用户的MES系统,使用户更加精确科学的分析用电量,从而提高设备的安全运行水平。

In the production of internal mixers,manufacturers require workers to manually record the electricity meter of the mixer every day,and compare the daily electricity consumption (or single rubber mixing electricity consumption) of the mixer to determine if it is consistent,in order to analyze the operation of the equipment.However,manual meter reading has low efficiency,and the more production lines there are,the longer the time consumption,usually exceeding one hour.Moreover,the accuracy of manually copying data is poor.By using smart meters,the problem of low efficiency in manual meter reading and inability to read hourly sub item data within the meter has been solved.By using the SIMATIC S7-1500 PLC for PN communication in the mixing machine control system,the information of the electricity meter can be quickly and accurately transmitted to the user's MES system,enabling the user to analyze the electricity consumption more accurately and improve the safe operation level of the equipment.
