摘要：我国正处在经济社会发展的战略转型期，经济增长方式由粗放向集约转变。国家“十一五”规划提出走新型工业化道路，加快制造业信息化，以信息化改造制造业，推进生产设备数字化、生产过程智能化和企业管理信息化。以工业控制计算机加组态软件为核心的计算机控制系统开始在中小型企业应用普及。各职业院校纷纷开设计算机控制技术和组态软件应用技术课程，以满足社会的人才需求。某酚醛树脂厂一车间现有五台5立方米的不锈钢蒸汽加热反应釜，反应釜生产出的酚醛树脂要先放料到储液罐，然后经造粒工序造粒包装成成品，原先储液罐工序采用人工手动控制，控制蒸汽阀门的开度，由于蒸汽的压力不能保持稳定，导致储液罐温度不能保持在一个理想的范围，现利用三文力控组态软件进行自动控制改造。10776

Phenolic resin liquid storage tank temperature control design
Abstract：Our country is in strategic transition period of economic and social development, the transformation of the economic growth mode from extensive to intensive. The national "eleven five" plan to take a new road to industrialization, speed up the informatization of manufacturing industry, manufacturing industry to promote the transformation of information, production equipment, production process of digital intelligent and informational management of enterprise. Control in industrial control computer and configuration software as the core of the computer system became popular in small enterprise application. The occupation colleges have set up the computer control technology and the application of configuration software technology courses, in order to meet the social demand for talents. A phenolic resin factory workshop of five existing 5 cubic meters of stainless steel reactor steam heating, phenolic resin reactor to produce must put the expected reservoir, then granulating process granulation packaging into finished products, the original reservoir operation by manual control, the opening degree control steam valve, the pressure can not be steam the stable, resulting in liquid storage tank temperature cannot be maintained in an ideal range, we use three-dimensional force control configuration software for automatic control transformation.
