一、概述 板式过滤器是为有色金属板带材轧制提供润滑冷却液的一种高效精密过滤装置(过滤流量0.15L/min～10 m~3,过滤精度≤0.5μm)。为了保证过滤精度,在过滤过程中需经常补充助滤剂,并定期进行滤箱的清洗、吹干、开箱换纸等操作。板式过滤器的控制系统由控制开关与限位开关、E-64PC机、电磁阀与接触器、气动薄膜阀与电机等组成。PC机根据过滤器不同的工作过程,按照一定的时间及顺序自动控制各气动薄膜阀,油泵及开合箱电 First, an overview Plate filter is non-ferrous metal sheet and strip lubrication to provide a cooling fluid efficient precision filtration device (filtration flow 0.15L / min ~ 10 m ~ 3, filtration accuracy ≤ 0.5μm). In order to ensure the accuracy of filtration, the filtration process often need to add filter aid, and regular filter tank cleaning, drying, unpacking and other operations. Plate filter control system consists of control switch and limit switch, E-64PC machine, solenoid valve and contactor, pneumatic valve and motor components. PC machine according to the different working process of the filter, according to a certain time and sequence of automatic control of the pneumatic valve, oil pump and opening and closing box
