摘　　要：为增强血液透析水处理器的可靠性及控制精度,同时方便医务人员操作,设计一套基于可编程控制器(PLC)的直供式双级反渗透水处理控制系统。对直供式双极反渗透水处理器的各组成部分进行电气控制设计,使系统实现自动冲洗、数据监测、故障报警以及按需选择单、双级控制水等功能。采用PI控制技术不仅能保障水处理产水水压恒定,还能根据实际用水量自动调节产水水量,达到节约用水的目的。实验运行结果表明,该系统运行稳定,操作简单,产水水压恒定。To improve the reliability and control accuracy of hemodialysis water treatment,and make the medical staff operate convenient,a direct supply of dual-stage reverse osmosis water treatment control system is designed,which is based on programmable logic controller（ PLC）. The system has a single and two-stage water system,automatic washing,data monitoring and fault alarm functions,This is owe to the design of electrical control of the hemodialysis water treatment. The purpose of using the PI control technology can guarantee water production constant water pressure,and water treatment still can automatically adjust the water production according to the actual amount of water to save water. Experiment results show that the system is stable to run,simple to operate and the supplied water pressure is constant.
