双源热压机快速恒温控制装置的设计及其控制流程

Design and control diagram of the control equipment with quickly constant temperature of hot-press machine with double energy

对现有的单源热压机载热体输送装置进行改进,设计了一种以导热油为主加热源,以蒸汽为辅助热源,以水、冷导热油为冷却剂的人造板热压快速恒温控制装置;确定了温度串级-流量分程-时间程序混合控制系统及程序流程.该控制装置及系统可使不同冷、热载热体同时或分时进入热压板的相应孔道,实现双源同时快速加热、冷却,保温保压阶段快速达到恒温.

The control equipment of quickly constant temperature using thermal oil as main heating source,vapor as assistant heating source,water and cool oil as cooling source,was designed by improved hot-press machine of artificial platen with signal energy.The control system was constituted by temperature in channel of hot-press platen and temperature of heat carrier oil in top pipe and time program. The cool carrier and heat carrier transported in corresponding hole in hot-press platen simultaneously or in different time to make hot-press platen quickly up to constant temperature by double heat carrier in control system.
