(3) Maintenance procedure card. (4) Completion report form. 11. What is the purpose of establishing maintenance operation standards? The purpose of establishing maintenance operation standards is to improve the quality of maintenance work ； Reduce the time required for maintenance tasks ； Eliminate accidents during maintenance work ； 12. What is the routine inspection and maintenance system, and what are the “four maintenances” for equipment? The four aspects of maintenance are: maintaining the clean appearance of the equipment, preserving its structural integrity, ensuring the accuracy of its performance, and maintaining its level of automation. 13. What standards should be included in establishing a standardized management system for equipment? Establish a standardized management system for equipment, which should include: the technical standards for the equipment. Operating standards for the equipment. Inspection standards for equipment. Standards for the maintenance of equipment. As well as the work standards and management standards that correspond to it. 14. What are the main aspects of the basic content of modern equipment management? The basic elements of modernized equipment management include: modernization of management philosophy, modernization of management objectives, modernization of management policies, modernization of management methods, modernization of management organizations, modernization of management standards, modernization of management approaches, modernization of management tools, modernization of management personnel, and modernization of management measures. 15. What are the management objectives for inspectors? The management objective for inspectors is. (1) Ensure the equipment meets the \"four maintenances\" (appearance, performance, precision, automation) to keep it in optimal operating condition. (2) Ensure that the equipment achieves maximum economic benefits with the minimum use of human, material, and financial resources. (3) Use reduced failure rate and maintenance costs as evaluation indicators. (4) Maintain a proactive spirit through self-management. 16. What are the factors and prerequisites that determine the inspection cycle? The factors and prerequisites that determine the inspection cycle are: equipment utilization rate, monthly production volume (operating hours) ； Usage conditions, proper operation status ； Working environment, temperature, humidity, dust ； Lubrication condition, lubrication method and status ； Impact on production, importance of equipment ； Usage performance, usage situations in other similar factories ； The recommended value by the equipment manufacturer. 17. What are the bases for formulating maintenance operation standards? The basis for formulating maintenance operation standards includes: **and the relevant standards and regulations issued by the industry ； Equipment operation manuals and drawings provided by the manufacturer ； Technical standards for equipment maintenance ； Maintenance standards for similar equipment at home and abroad ； Regarding safety procedures and process specifications. 18. What are the bases for formulating inspection standards? Basis for formulating inspection standards: equipment operation manuals and relevant technical drawings. Maintenance technical standards. Refer to similar practical materials from home and abroad. Accumulated practical experience through the PDCA cycle. 19. What are the main contents of the maintenance technical standards? The main contents of the maintenance technical standards include: the name of the equipment, device, or component, a schematic diagram of its location, the part name, the material used, the maintenance standards, the methods for inspection or testing, the frequency of inspections or maintenance, the cycle for replacement or repair, and any special considerations related to maintenance. 20.
