密相气力输送系统

粉

密相气力输送系统适用于粉体、颗粒等干散物料的高正压慢速输送。这种输送方式主要用于研磨性、易碎性和/或爆炸性产品。必威体育app官方下载产品转移在连续批次和插头中进行。每个输送循环包括以下几个阶段:灌装阶段，灌装阀开启，放空阀开启。该产品填充容器(罐)并置换罐内的空气。高电平控制装置向进给阀和放空阀发出关闭信号。出口夹阀(如果安装了)保持关闭状态。压缩空气进口阀门打开，压缩空气进入容器。产品与空气混合并开始流化。当容器内的压力达到输送所需的水平时，出口阀门打开，产品被向前推入输送管道。 The product moves in successive plugs until the vessel and the pipeline are empty. A single pressure switch controls the pressure in the vessel and as soon as the pre-set limit of the cycle end has been reached, it stops the air compressed supply. The residual air allows purging the circuit until the pressure differential has been dispersed. A principal advantages of this method are : Particularly suitable for ATEX installations, It preserves the original appearance of the product, Low power consomption
