Chemical Production Workshop of Huangling Coal Chemical Company: Small maintenance cards play a big role Author/Source: Shaanxi Coking Chemical Co., Ltd. Date: 2022-06-08 Views: 20 Recently, the Chemical Production Workshop of Huangling Coal Chemical Company has taken a series of measures to strengthen the basic management of equipment. In particular, the comprehensive implementation of integrated management for equipment maintenance assignments and status cards has ensured that there are people responsible for keeping the equipment clean, for its maintenance, for monitoring its condition, and for planning its replacement – thus laying a solid foundation for the long-term stable operation of the equipment. On the small charter flight card, not only are various operating statuses such as in operation, waiting for materials, stopped, and under maintenance indicated, but there is also a complete set of service teams including the operational charter manager, electrical charter manager, mechanical charter manager, and instrumentation charter manager. According to the personnel in charge, the charter tickets not only enable closed-loop management of the equipment but also make the allocation and implementation of responsibilities clearer. Compared to the previous version, the new charter status display uses a rotating disc to indicate the current operating status, making it intuitive and interesting. The charter information can be changed easily and quickly, the surface is clean and durable, and it is firmly fixed in place. “The chemical production workshop is characterized by complex production processes and a variety of equipment; the entire production process can only be carried out through the coordination of static and dynamic equipment, which makes management challenging. To facilitate management and improve the operational efficiency of the equipment, the workshop initially took crude benzene as a pilot project, combining equipment chartering with status signs into one system. It revised the chartering regulations and established uniform standards for display, and good results were achieved through trial operations. ”Liu Gang, the process technician at the workshop, explained. At present, the new charter flight system and charter flight cards across the entire workshop have been fully implemented; a total of 388 of these have been replaced. This not only facilitates safe production but also enables standardized management of work positions.
