渣浆泵无人值守的控制策略及实现方法

针对选矿生产中渣浆泵运行时离不开现场岗位操作人员的现状,提出了一种渣浆泵无人值守的控制策略及实现方法,通过对渣浆泵的启动条件、倒泵操作以及停泵后的清洗等环节进行自动控制,大大简化了渣浆泵操作的流程;采用和利时的PLC和触摸屏作为实现手段,就近采集信号,对渣浆泵进行控制,并可与中控实时通信,实现远程控制,取消了岗位操作人员,实现渣浆泵的无人值守,节省了人力资源。

In view of the current situation that the slurry pump can’t be operated without on-site operators in beneficiation production,this paper puts forward a control strategy and realization method of the slurry pump without attendance.Through the automatic control of the starting conditions,the operation of the reverse pump and the cleaning after the shutdown of the slurry pump,the operation of the slurry pump is greatly simplified.By using Hollysys PLC and HMI as the means of realization,the slurry pump can be controlled automatically,the signals can be collected nearby,and real-time communication with the PCS can be achieved to eliminate the post workers,realize the slurry pump unattended,and save human resources.
