Hydraulic components will develop in the direction of high performance, high quality, high reliability, and complete systems; low energy consumption, low noise, vibration, no leakage, pollution control, application of water-based media, etc. to meet environmental protection requirements; the industry will strive to develop high Integration, high power density, intelligence, mechatronics, light, small, and micro hydraulic components; actively adopt new technologies, new materials, electronics, sensing and other high-tech. Throughout the development of the industry, intelligence, energy saving, green, and reliability are the main trends of future industry technology development. 1. The development trend of intelligent future machinery and equipment is first to improve safety and reduce labor intensity.

Therefore, the operating system is inevitably required to be easy to operate and friendly to human-machine interface, and even to achieve automation and unmanned; secondly, it is required to improve the precision and dynamic performance of the machine , The motion and power control system is required to improve the accuracy of the machine; in order to improve the reliability and long life of the product during the service period, reduce maintenance time, and reduce personnel costs, the system is required to have the capabilities of status monitoring, fault diagnosis and intelligent maintenance. The hydraulic component industry must meet the requirements of host equipment by improving its own intelligence. Intelligent technology for the entire life cycle of hydraulic component products is an important technological development requirement to meet the needs of machinery and equipment in the future. 2. Energy saving, low carbon, energy saving, emission reduction, and environmental friendliness are the strategic requirements for the sustainable development of the hydraulic industry. In the future, structural optimization and active control methods will be used to improve the efficiency of components and systems, and reduce the vibration, noise and transmission medium of components and systems The leakage and electronic control replace the traditional mechanical and pilot control modes in the variable components, and the functions are determined by the software program, which enhances the global optimization and matching ability of the system. 3. Process pollution of green hydraulic components and parts in the manufacturing process, product vibration and noise, material loss, medium leakage and other issues have always been important challenges facing my country's hydraulic industry. In the future, it is necessary to apply green manufacturing technology to the whole life cycle process of product design, process, manufacturing, use and recycling. Reduce the vibration and noise of components and systems through structural optimization technology and active control principles.

The industry will gradually phase out surface treatment and manufacturing processes that are harmful to the environment, and adopt environmentally friendly manufacturing methods and equipment, such as net forming technology, cutting processing optimization technology, dry cutting technology, etc., to improve resource and energy utilization rates and raw materials in the manufacturing process Conversion rate, reduce the generation of polluted wastes and pollutants and the emission of toxic substances in the product manufacturing process; promote the application of environmentally friendly media, develop new materials and environmentally friendly materials that reduce friction and reduce component loss, and improve material utilization ; Through the development of pipeline connection technology, research and development of new sealing materials, optimizing the sealing structure and finishing technology, improve product sealing performance, reduce media leakage and pollution; develop fluid media recovery and reuse technology, develop special component disassembly, Recycling and remanufacturing processes and production lines, improving the performance evaluation methods of remanufactured components, and improving product recyclability and remanufacturing levels. 4. Reliability my country's hydraulic products have long-standing problems of poor reliability and low service life, which directly affect the overall reputation of the industry. Many complete machine manufacturers dare not use domestic hydraulic brands for a long time, and end users are also opposed to using them. For a long time, my country's hydraulic products have long been dependent on imports. Therefore, reliability is the most important issue that restricts the development of the industry.

The reliability of the hydraulic industry started late, and most of them borrowed the research results of the mechanical industry reliability, electronic reliability and other related fields, but failed to comprehensively consider its own multi-field coupling, nonlinearity, and complex vibration characteristics; reliability and failure prediction The real-time performance is insufficient; there is no uniform reliability research standard. Therefore, how to establish effective and comprehensive reliability research will be an important technical and scientific issue for future industry development.
