基于PLC的磨削冷却水处理控制系统设计

Based on the PLC grinding cooling water treatment control system design

该系统采用PE烧结微滤膜对循环使用的磨削冷却水进行集中过滤,利用高压脉冲反洗法来解决微滤膜的通量衰减问题,并在整个过程中辅以PLC自动控制,将冷却水中杂质粒度控制在0.5μm以下,明显提高了冷却水的水质,增加了冷却水的循环使用次数.

The system uses a centralized filter PE sintered micro-membrane recycling of grinding cooling water,uses the high-voltage pulse backwash method to solve the problem of microfiltration membrane flux attenuation,and the system supplemented by PLC automatic control in the whole process,the cooling water impurities,particle size is controled at the 0.5 μm below,significantly improves the water quality of cooling water,increases the frequency of use of the cooling water circulation.
