A system of supercritical CO 2 extraction distillation and a unit of preventing CO 2 from back flow and distributing CO 2 were designed. Experiment on extraction distillation of wheat germ oil was carried out in this system. 设计了超临界CO2萃取-精馏系统和超临界CO2止逆分布器,并在该系统上进行了小麦胚芽油的萃取-精馏试验研究。
Introduces the detail hardware structure, software configuration, the concrete PLC configuration and communication mode, the PLC programming method and diagram flow of the distributing system. 详细阐述了该系统的硬件结构及软件组成以及PLC的具体配置,该系统的具体通信方式及下位机软件的编程思想及方框流程。
Power flow level difference, a new evaluation method, can describe vibration energy distributing and attenuation discipline in the system but have its difficult measurement. 功率流落差作为新的评价方法,可以直观描述系统中振动能量分布与衰减规律,但测量困难。
