"Regulations on Equipment Management" stipulates that "enterprise equipment management should rely on technological progress, promote production development and give priority to prevention". These are the three principles of equipment management in China. 1. Equipment management should adhere to the principle of "relying on technological progress". Equipment is the carrier of technology. Only by continuously injecting advanced scientific and technological achievements into equipment and improving the technical level of equipment can we ensure the realization of the daily goals of production and operation of enterprises and maintain the ability of sustainable development of enterprises. Since the reform and opening up, China's equipment management has adhered to this policy, broken through the old framework of original repair in equipment management and maintenance, established a new concept of combining repair, transformation and renewal, and promoted the improvement of equipment quality and the development of productivity in enterprises. Equipment management depends on technical progress. First of all, we should improve the technical quality of the equipment itself. On the one hand, it is necessary to replace backward equipment with advanced equipment and implement technological upgrading; On the other hand, new technology is adopted to transform existing equipment, improve technical level and prolong technical life. Secondly, while improving the technical level of equipment, we should also attach importance to education and training, constantly improve the technical level and professional ability of equipment managers and maintenance personnel, and adopt advanced management methods and maintenance technologies, condition monitoring and diagnosis technologies to continuously improve the modernization level of equipment management and maintenance. 2. Equipment management should implement the policy of "promoting production development". The fundamental purpose of equipment management is to protect and develop social productive forces and serve the development of production and prosperity of socialist economy. Therefore, the Regulations on Equipment Management stipulates "promoting production development" as one of the basic principles of equipment management. To adhere to this policy, we must correctly handle the dialectical relationship between enterprise production and equipment management. They are basically unified, but sometimes there are contradictions. For example, arranging equipment maintenance takes up production time and temporarily reduces output and output value. At this time. There is a contradiction between production and equipment maintenance. However, if the necessary equipment maintenance is not carried out in time, or even the practice of "the donkey will not die without grinding" will inevitably lead to various accidents, paralyze production and even cause irreparable losses, which is the intensification of the contradiction between the two. Therefore, the person in charge of the enterprise and the production and operation departments must raise their awareness and put equipment management in an important position. While arranging and checking the production plan, we should arrange and check the equipment maintenance and overhaul plan, consciously maintain the good condition of the equipment and improve the technical quality of the equipment. In particular, the so-called service for the development of production is not only to serve the completion of the current production and operation plan, but also to pay attention to the preservation and appreciation of the assets owned by enterprises, improve the technical level, maintain the "stamina" and serve the long-term development goals of enterprises. It can be seen that the short-term behavior of relaxing equipment management, ignoring equipment maintenance and even "killing the goose to get the egg" is obviously very harmful. 3. Equipment management should implement the policy of "prevention first". The early meaning of "prevention first" means that both equipment maintenance and overhaul are based on prevention. Under the condition of carrying out comprehensive equipment management, prevention first has been given a new connotation and developed into a guiding principle throughout the whole life of equipment. On the one hand, enterprises using equipment and their competent departments should establish the guiding ideology of "prevention first" and "prevention is more important than treatment" in equipment management, and pay attention to the reliability and maintainability of equipment at the stage of equipment procurement. Strictly abide by the operating rules of using equipment, strengthen daily maintenance and prevent abnormal deterioration of equipment; Carry out preventive periodic inspection, test and equipment status management, grasp the signs and development trends of equipment failure, formulate effective maintenance countermeasures in time, and try to turn unplanned after-the-fact maintenance into planned preventive maintenance as much as possible, eliminate hidden dangers, reduce unexpected downtime and give full play to equipment efficiency. On the other hand, for equipment design and manufacturing enterprises and their competent departments, we should take the initiative to do a good job of after-sales feedback of equipment to improve the design performance and manufacturing quality of equipment. Fully consider reliability and maintainability in the development of new equipment and implement "maintenance prevention"; For some products, we can strive for the higher goal of "maintenance-free design".
