某碳酸盐泵启动控制方案的设计与应用

The design and application of a control scheme for start-up of a carbonate pump

该文以独山子石化公司某厂乙二醇装置工程改造为例,详细描述了改造过程中碳酸盐泵启动电路中采用PLC控制软启动器的设计方案与应用。实际应用表明,该设计方案能够完成控制要求,达到系统安全稳定运行的目的。

In this paper, a plant in Dushanzi Petrochemical Company ethylene glycol unit engineer- ing as an example, detailed describes the transformation in the process of PLC control in carbonate pump start - up circuit design and application of soft starter. Practical application shows that this design scheme can complete control requirements, achieve the goal of system security and stability and operation.
