可编程逻辑控制器和触摸屏组成的清洗设备恒压供水控制系统

Cleaning equipment water supply control system comprised PLC and touch-screen

介绍了应用在拖拉机底盘件清洗设备上的由西门子S7300 PLC、触摸屏、变频器等控制设备构成的喷淋水泵恒压供水控制系统,可在触摸屏上实时设定、显示供水压力、修改PID控制参数,并可提供报警信息,简单直观,便于操作和维修,对喷淋压力进行控制,使其保持恒定、平稳,对提高拖拉机底盘件清洗质量起到明显的作用,并有一定的节能效果。

This paper introduces the design of a constant pressure water supply control system used in the cleaning machine, which Constitute with Siemens S7300 PLCses, touchscreen, converter etc. This system can set the supply water pressure and show it on line, modification PID control parameter, provide the report of fault alert. This system is easy to operation and maintain, can made the pressure water supply constant, obvious raising clean quality of tractor bedrock, also have certain economy en- ergy effect.
