自动控制器

The process of powder soution preparation operates each soution tank gade, they are bocked off. it coud assure the best reaction time invariabeness consistency of every soution tank, avoid any direct touch of prefabricated tank iquid storage tank, the automatic contro system ised with eve sensor, to gain the exactitude consistency. When the eve reaches ow, the soenoid vave open, the powder feeding started. Opposite, the eve reaches high, the circe process stop.

干粉溶液制备过程是通过各个溶液槽分级逐步完成的，溶液槽之间隔开，保证每个溶液槽内的最佳反应时间和恒定浓度，避免在预制槽和药液储存槽之间有任何直接通路，自动控制系统与储存槽上的液位控制器相连，一旦液位达到低位，触发进水电磁阀打开，干投机启动，投加量安装水量设定，以获得精确浓度，当液位达到最高点，此循环过程就停止，当然搅拌器还按设定时间继续工作。
