- Integrating hydraulic energy-saving technology into hydraulic theory and practice courses.Here, students first need to clarify the energy loss characteristics of each energy unit in a hydraulic system and integrate hydraulic energy-saving technology from a component selection perspective. They are then required to master the design of various energy-saving hydraulic circuits, including quantitative pumps and variable frequency speed control motor electro-hydraulic systems, load sensitive control systems, and secondary regulation hydrostatic transmission systems. Finally, students are required to understand the application of other energy-saving technologies, such as installing energy recovery devices, adopting new power systems, and using advanced computer technology to improve control systems.Consequently, practical coursework is an effective means through which students and teachers can better understand and master hydraulic energy-saving technology, ensuring better integration of hydraulic energy-saving technology into the mechanical engineering teaching and research process, over and above the integration of hydraulic energy-saving technology into the classroom. By designing experimental courses related to hydraulic energy-saving technology and building corresponding experimental platforms, students can further consolidate their theoretical knowledge. Additionally, teachers can better integrate hydraulic energy-saving technology research results into the teaching process, and students can be encouraged to apply their knowledge during enterprise training to solve the current energy-saving and emission-reduction problems that enterprises may be facing, as shown in Figure 5.
- Building a platform for school–enterprise cooperation, achieving course integration, and building a new cooperative talent cultivation model.Utilization efficiency can be improved by integrating the educational resources of colleges and universities with the industrial resources of enterprises. In the teaching process, the school sets the hydraulic transmission class for the enterprise, or the enterprise provides practical skills guidance for students so that they can experience the business environment and gain operational experience before graduation. Enterprises regard students as their own employees, and unified enterprise management and assessment processes are conducted with them—that is, the training of high-quality, skilled talent to meet the needs of the enterprise can be considered to be the educational goal. Accordingly, reaching a consensus with the school to create an appropriate teaching mode for their joint training requirements is essential. Through the construction of a school–enterprise cooperative platform, the application of hydraulic energy-saving technology in teaching, research, and engineering practice can be further promoted by the organic combination of classroom teaching and practical training operations, cultivating a comprehensive teaching mode suitable for different industries and enterprises.
- Promoting teaching through research.Hydraulic energy-saving technology research can be introduced into the teaching content and course design, such that classroom teaching and practical content can be improved. Teachers can actively apply for research projects related to hydraulic energy-saving technology and allow students to participate in the completion of research content derived from relevant research projects, improving their cognitive abilities with respect to hydraulic energy-saving technology, and further promoting such research progress.
- Teacher cultivation.The teachers of hydraulic transmission courses should visit hydraulic-related enterprises to conduct in-depth research, master the latest hydraulic energy-saving technologies, engage in related research, and achieve specific research outcomes. Moreover, experts in the field can be invited to conduct academic lectures to improve the quality of teaching.
- Competition to promote learning.Various hydraulic transmission technology innovation competitions at all levels can be conducted to improve the cognitive abilities of students related to hydraulic energy-saving technologies. Students can be encouraged to participate actively in various energy-saving and emission-reduction competitions and to strengthen their understanding of green manufacturing and related energy-saving concepts.
