The motor pump is used in petrochemical plant, and plays an important role in safe and stable operation. All kinds of safety interlocking and sequence control in refinery contain a lot of motor pump interlock control the start and stop. The motor pump interlock start-stop control is complicated and has many solutions. The author summarizes the experience of engineering design in recent years and briefly expounds the relevant common control schemes. Then the author puts forward the recommended scheme and explains the related contents of the arrangement of the intermediate relay and the signal line. Through the discussion and analysis, the author would like to provide some inspiration for the reasonable design related content.%电动机泵是石油化工装置内的常用动设备，对炼化装置的安全稳定运行有着重要作用。在炼化装置的各类安全联锁、顺序控制等关键控制方案中，会涉及到很多对电动机泵的联锁启停控制。电动机泵的联锁启停控制比较复杂并且方案很多，通过总结最近几年炼化装置电动机泵启停联锁控制的工程设计经验，简要阐述了电动机泵联锁启停的常用控制方案，提出了互为备用机泵的联锁启动的推荐方案，同时对中间继电器布置、信号线布置等相关内容进行了说明。本文通过相关论述和探讨，为炼厂工程设计人员合理设计电动机泵电气联锁控制提供一点启示。
