This course is the core professional basic course of mechanical specialty and the key bridge connecting mechanical design and industrial control, which is both theoretical and practical. This course takes the principle of fluid transmission-component structure-control logic-system application as the main line to build a complete knowledge system. Starting from the basic knowledge of hydraulic transmission, the course analyzes the principles, application scenarios and system composition of hydraulic and pneumatic transmission. Then, the structure and working principle of power and executive components such as hydraulic pump and hydraulic cylinder are deeply explained, with emphasis on the core characteristics of gear pump, vane pump, piston pump and various control valves. On this basis, the working mechanism and application scenarios of control elements such as reversing valve, overflow valve and throttle valve are systematically taught, as well as the construction and debugging methods of typical hydraulic circuits, covering the design of key circuits such as volume speed regulation, sequential action and PLC control. The ideological and political elements of the course are integrated into the teaching. Through the case of independent innovation of domestic hydraulic components, students are guided to establish the consciousness of self-reliance and self-improvement in science and technology, and the rigorous and meticulous craftsman spirit is cultivated. Through the combination of theoretical study and practical training, students will master the analysis, design and debugging ability of hydraulic and pneumatic systems, lay a solid foundation for subsequent professional course study and engineering application, and help solve fluid transmission engineering problems in intelligent manufacturing, construction machinery and other fields.
