啤酒清洗灌裝控制系統(tǒng)設(shè)計(jì)

摘      要

本設(shè)備是專為啤酒桶的清洗、消毒設(shè)計(jì)的。該設(shè)備可以自動完成清洗消毒及CO2備壓等全部工序。本設(shè)備適用桶的尺寸為高度H360—H560，直徑Φ250—Φ500。本機(jī)主要由機(jī)架、電氣控制箱、電磁閥、氣動元件、氣沖系統(tǒng)和水路系統(tǒng)組成。本機(jī)控制單元采用以三菱公司的可編程控制器為核心對機(jī)器進(jìn)行全過程控制。由于可編程控制器在工業(yè)控制方面的應(yīng)用意義日趨明顯，已在機(jī)械制造、發(fā)電、化工、電子等行業(yè)工藝設(shè)備的電氣控制方面得到了廣泛的應(yīng)用。它具有功能強(qiáng)大、使用可靠、維修簡單等許多優(yōu)點(diǎn)，并且在很多地方已逐步取代了繼電器電路的邏輯控制。本文討論的是PLC在實(shí)際工業(yè)控制系統(tǒng)的應(yīng)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—560.The diameter is 250—500. The equipment is made of chassis, control unit, electromagnetic 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.
