摘　　要：在分析、对比目前市场上颗粒干冰制造机液压控制系统优缺点的基础上,设计了一种新型的基于PLC自动控制的颗粒干冰制造机的液压控制系统。该系统通过PLC对电比例液压泵流量、压缩雪花干冰主油缸行程和电磁节流膨胀阀充液时间参数的联合控制,不仅实现了颗粒干冰的全自动可视化生产,而且实现了颗粒干冰产能的无级调节,从而提高了产品的生产效率和竞争力。On the basis of analysis and comparison to various particles of dry ice maker machine hydraulic control systems,a new hydraulic system based on PLC was designed. Its hydraulic control system was applied PLC to control of electric proportional pump flow,main cylinder stroke and solenoid throttle expansion valve filling time,and got automotive manufacturing process and particles of dry ice capacity adjusting in stepless,which also improved production efficiency and competitive strength.
