文档介绍：啤酒清洗灌装控制系统设计
摘要
本设备是专为啤酒桶的清洗、消毒设计的。该设备可以自动完成清洗消毒及CO2备压等全部工序。本设备适用桶的尺寸为高度H360—H560,直径Φ250—Φ500。本机主要由机架、电气控制箱、电磁阀、气动元件、气冲系统和水路系统组成。本机控制单元采用以三菱公司的可编程控制器为核心对机器进行全过程控制。由于可编程控制器在工业控制方面的应用意义日趋明显,已在机械制造、发电、化工、电子等行业工艺设备的电气控制方面得到了广泛的应用。它具有功能强大、使用可靠、维修简单等许多优点,并且在很多地方已逐步取代了继电器电路的逻辑控制。本文讨论的是PLC在实际工业控制系统的应用。

Beer Cleaning Filling Control System Design
Abstract
This equipment designed for cleaning and sterilizing casks. The equipment is automatic. The key processes contain discharging remnants, swilling with water, swilling with disinfectant, swilling with aseptic water and inflating with CO2. The height of cask is 360— diameter is 250—500. The equipment is made of chassis, control unit, ic valve and piping. The center of manipulative unit is the MITSUBISHI PLC. PLC controls all of the running processes. Applied meaning that programmable logic controller have in its control the aspect in the industry gradually obvious, combine at manufacture,generate electricity, chemical engineering, electr
onics etc profession craft the equipment's electricity control the aspect got the extensive application. It have the function strong and big, the usage is dependable, maintain the many advantage of simple etc., and already and gradually replaced after the logic control of the electric appliances electric circuit in a lot of places. But what the text discussion is a PLC in the actual industry to control the system's application.
