往复式冷冻压缩机自动控制系统的设计和实施

Automatic Control System of Reciprocating Refrigeration Compressor

在C-503压缩机的自动控制系统改造中PLC替代了继电器控制电路,在设计时充分发挥了PLC的优势,结合工艺需要设计出合理的仪表控制方案,使原控制系统的联锁控制和载荷切换控制中的多项缺陷得到完善,PLC的采用是使这一控制方案得以完美实现的关键。

C-503 compressor in automatic control system for the transformation of the PLC Replaced the relay control circuit,in the design and give full play to the PLC advantage,combined with the design process required a reasonable instrument control program,so that the original control system of interlocking control and load switch control of a number of defects has been improved.PLC adoption is to make the control scheme to achieve a perfect key.
