As refining units continue to scale up and operate with increasing continuity, the safety management and standardized maintenance of pumps in catalytic cracking units are becoming increasingly important. Recently, the No. 1 Refining Department of PetroChina Guangxi Petrochemical Company initiated an update of the energy isolation diagrams for pumps in the catalytic cracking unit. By systematically reviewing and standardizing the management of 46 sets/units of pumps, this effort further solidifies the foundation for safe and stable operation of the unit. As a core production unit in the refining system, the catalytic cracking unit's pumps operate under long-term conditions of high temperature, high pressure, flammability, explosiveness, and complex media. Inadequate isolation measures can easily lead to safety risks such as leaks, misoperations, and equipment damage. Therefore, establishing comprehensive, precise, and visualized energy isolation diagrams for pumps is of great significance for ensuring maintenance safety and standardizing on-site operations. It is recommended to further strengthen the following aspects in subsequent pump management: First, continuously improve the digital management of pump isolation points, integrating with the DCS system and intelligent inspection platform to achieve online confirmation of isolation status and full-process traceability. Second, establish specialized isolation standards for key equipment such as high-temperature slurry pumps, circulating oil pumps, and critical process pumps in the catalytic cracking unit, detailing isolation requirements for drains, ball valves, seal flushing, and auxiliary systems. At the same time, enhance on-site standardized training through graphical, three-dimensional, and case-based teaching to improve new employees' understanding of pump structures and isolation logic. Additionally, it is recommended to promote the upgrade of pump equipment towards intelligence, low leakage, and high reliability, such as applying online vibration monitoring, intelligent lubrication management, and high-reliability mechanical seal technologies to further reduce equipment failure rates and unplanned shutdown risks. In the future, with the digital and intelligent development of the refining industry, pump management in catalytic cracking units will gradually shift from "experience-based operations" to "standardized, visualized, and intelligent" approaches, providing a more solid guarantee for the long-term safe and stable operation of refining units.
