Description
称量控制原理如下:
若检测重量大于快供值,则快供电机启动,慢供电机停止;若检测重量大于慢供值且小于快供值,则慢供电机启动,快供电机停止;若检测重量大于提前值且小于慢供值,则慢供电机停止,快供电机停止.
液体称量
液体部分称量包括烧碱、泡花碱、水、磺酸、非离子A及非离子B等六种物料.其中,烧碱、泡花碱和水共用一个称量斗,磺酸用一个称量斗,非离子A与非离子B共用一个称量斗,供料采用气动球阀实现.传统的称量控制方式采用称量控制仪(如PHILIPS公司的PR1615)实现,而在本系统中,称量控制是由S7 414完成的.
称量控制原理如下:
若检测重量大于快供值,则球阀开;若检测重量大于慢供值且小于快供值,则球阀点动开关;若检测重量大于提前值且小于慢供值,则球阀关闭.
