\"Rigorous Maintenance\" of Jinzhou Petrochemical’s Pumps Boosts Production Efficiency

Thread Content

As of May 19, data from Jinzhou Petrochemical’s Mechanical Equipment Department show that since the \"refinement\" of these pumps was carried out through measures such as optimizing pump models, cutting impellers, verifying flow rates by using appropriate impellers, replacing pump heads, and standardizing the type of coupling diaphragms, 41 pumps have benefited from these efforts, with a pass rate for each repair session being no less than 98%. 　　The \"meticulous maintenance\" of mechanical pumps is a practical approach taken by Jinzhou Petrochemical to achieve the overall goals of \"two types of management, one type of monitoring, and one type of reduction\" in the refining and chemical processing sector. They integrate the concept of \"meticulous maintenance\" from six aspects – maintenance procedures, maintenance tools, on-site standardization, documentation, quality control, and specialized management of bearing seals – to achieve \"three levels of precision\". “\"Three Precisions\": Precise classification. Pumps are classified into four grades, A, B, C, and D, based on safety and environmental risk, operational and maintenance risks, as well as their level of importance. These grades determine the appropriate maintenance strategies, inspection frequencies, and spare parts required, thereby laying the foundation for thorough maintenance. Precise operation and maintenance. Abandoning the extensive management approach of waiting until something breaks before taking action, and adopting a strategy that focuses on prevention and maintenance with repairs as a secondary measure; by enhancing the planning of repairs and increasing efforts in the operation, management, and maintenance of equipment, as well as implementing series sealing for pumps in high-risk situations, the level of risk control for equipment has been significantly improved. Through thorough evaluations, the machining skills and professional capabilities of technicians in equipment management are effectively improved. Risk assessments, identification of potential hazards, and remediation actions are carried out on a regular basis to ensure that the records related to pumps are kept up to date. This approach facilitates a closed-loop system for statistical analysis, thereby accelerating the process of refined management of mechanical equipment.
