在工业生产自动控制中,为了生产安全或为了保证产品质量,对于温度、压力、流量、成分、速度等一些重要的被控制参数,通常需要进行自动检测,并根据监测的结果进行相应的控制。在自动监测系统中,常常设有上下限检查、报警及自动处理系统,以提醒操作人员注意,必要时采取紧急措施。
温度是工业生产对象中主要的被控制参数之一。本文介绍江苏金维卡纤维有限公司-大丰3.5万吨粘胶纤维项目中的一道烘干系统中的温度的控制系统。
该化纤纺织中一道烘干系统中的温度的控制系统主要通过GGD电气控制柜、浙江中控的DCS集散控制系统、现场的热电偶和电磁阀来完成的,实现一道烘干系统的温度保持在一定的范围内,满足生产的要求。

Industrial production in automatic control, in order to ensure production safety, or to product quality, temperature, pressure, flow, composition, speed, and so were some important control parameters, usually the need for automatic detection and monitoring in accordance with the results of the corresponding control. The automatic monitoring system, often with the limits of inspection, and automatic alarm system to alert operators of attention, if necessary, take urgent measures.
Temperature is the object of industrial production was the main parameters of control. This paper describes the Vicat Jiangsu Fiber Co., Ltd. - Dafeng 35,000 tons of viscose fiber project in a drying system of temperature control system.
The textile and chemical fiber in a drying system of temperature control system, mainly through GGD electrical control cabinet, and Zhejiang in the control of the DCS distributed control system, the scene of the thermocouple and to complete the electromagnetic va
