How to maintain the four major vehicles of a coke oven?

Purpose: Lubrication is a necessary condition for the proper operation of equipment. To reduce equipment wear, improve efficiency, lower consumption, and extend the service life of the equipment, these guidelines have been established for proper maintenance. Scope of application: Workshop. Specific details: Equipment maintenance management. 1. All equipment, pipelines, valves, etc. used in the workshop are subject to maintenance. 2 Maintenance and upkeep are carried out under a system of assigning specific aircraft or areas for responsibility; dedicated personnel are assigned to oversee equipment, pipelines, valves, etc., with the responsible persons indicated on site. 3 Each team shall keep the equipment in its area clean and promptly eliminate phenomena such as leaks, spills, and drips. 4 Each team should insist on cleaning, wiping, and maintaining the equipment in their assigned area at the end of each shift. 5 Maintenance personnel (mechanical, electrical, and instrumentation) must have clear divisions of labor; they should maintain the equipment under their responsibility in accordance with the equipment maintenance procedures and keep proper inspection records. 6. For key equipment, a strict \"three-level maintenance\" system is implemented. 7. Daily maintenance, abbreviated as \"daily upkeep,\" includes tasks such as lubrication, tightening, adjustment, cleaning, and routine monitoring; it is carried out by the operators on duty. Level 1 maintenance, abbreviated as “First Maintenance,” is carried out primarily by operators, with the assistance and guidance of maintenance workers. It involves accessing certain key parts of the equipment – those areas with high dust levels, significant wear, or frequent exposure to corrosion – where the equipment is partially disassembled for inspection. Tasks include cleaning, removing burrs, adjusting clearances, clearing oil passages, and tightening loose components. First Maintenance should be performed every 500 hours of operation, and operators are responsible for keeping records of this maintenance. 9 The secondary maintenance is abbreviated as “secondary upkeep”; it mainly involves the interior parts of the equipment, and is carried out primarily by maintenance workers, with the assistance of operators. The specific tasks involve partially disassembling the equipment for inspection and repair; in addition to carrying out the routine maintenance tasks, worn parts need to be replaced or repaired, the main precision parameters of the equipment are checked and adjusted, the lubrication system is cleaned and its oil is replaced, and the electrical system is inspected and repaired, so as to restore the equipment’s precision and ensure that it meets the specified technical parameters. Secondary maintenance should be carried out after the equipment has been in operation for 2,400–2,800 hours. The workshop equipment manager is responsible for keeping records of this secondary maintenance and recording them in the equipment files. 10 All spare equipment should be regularly inspected and maintained, with attention paid to protection against dust, moisture, freezing, and corrosion. For transmission and rotating equipment, it is also necessary to carry out regular turning operations and switching to keep all equipment in good condition, ensuring that it is truly ready for use when needed. 11 All equipment accessories, motors, and electrical switch boxes must be kept clean at all times; it is strictly prohibited to allow iron shavings or other debris to fall inside them. 12 Keep the tools used for lubrication, such as oil containers and oil guns, clean and in good condition. 3.8 Workshop equipment managers and team leaders should supervise and inspect the lubrication and maintenance of equipment, carefully summarize the experience of operators and maintenance workers in this regard, and continuously improve equipment management practices. The maintenance and inspection of important equipment such as the 13 large vehicles shall be carried out in accordance with the requirements specified in their respective operation and maintenance manuals; make full use of the maintenance time to thoroughly complete each task.

As part of equipment maintenance, the most important thing is to carry out regular inspections and upkeep. Among these maintenance tasks, the key aspect is the establishment and implementation of a system for lubricating the equipment. It is also necessary to improve operational management in order to minimize or eliminate human-induced damage to the equipment. Furthermore, it is essential to schedule timely minor and major repairs; one should not wait until the equipment is completely broken down before taking action to replace it. Doing so not only involves cost issues but also leads to a series of problems that are detrimental to the long-term stable operation of the equipment.

1. Pay attention to operating the equipment in accordance with the specifications, and avoid using it in a rough or improper manner. 2. Strengthen regular inspections, and address any issues that are discovered promptly for maintenance. 3. Make use of the maintenance time to resolve potential problems in the equipment, thereby preventing minor faults from escalating
