Experimental content
1. Observation and disassembly experiments on the structure and working principle of various components in hydraulic transmission
1) Surveying and analysis of mechanical components;
2) Learning and analysis of the principles of hydraulic control systems.
2. Hydraulic excavator demonstration control experiment
1) Excavation operations, bucket and stick composite work experiments;
2) Rotating operation, lifting the boom while the platform rotates;
3) Unloading operation, with both the boom and bucket working simultaneously, the position and height of the boom can be adjusted;
4) Return, the platform rotates, and the boom and stick cooperate to return to the starting position of excavation.
3. Programmable Logic Controller (PLC) Electrical Control Experiment: Mechanical Electrical Hydraulic Integrated Control Experiment.
1) Learning PLC instruction programming and ladder diagram programming;
2) Learning and using PLC programming software;
3) Communication and online debugging between PLC and computer;
4) The application of PLC in hydraulic transmission control and the optimization of control schemes.
Performance and characteristics
1. The experimental platform is made of cold-rolled steel plate (which has undergone spray coating and anti-corrosion treatment), with a desktop structure and integrated control operation.
2. The electrical operation control is bottom mounted, and the hydraulic station is placed in the main cabinet of the hydraulic platform. The overall structure is compact, coordinated, and the layout is beautiful and generous, with strong practicality, which can be used for 4-6 people to experiment.
3. The excavation machinery is a fully metal structure that is scaled down in proportion to the actual object. During the experiment, the hydraulic system is activated to operate the machinery according to the experimental requirements.
4. Excavation machinery is made according to the structure and reduced proportion of the physical object, which can truly reflect the actual working conditions of its machinery, enabling students to deeply understand the structure and working principle of its various components in experiments.
5. The experimental control adopts two methods: manual control and automatic control.
6. The experimental components use pressure resistant rubber hoses, with a pressure of up to 25Mpa.
7. Equipped with three-phase leakage protection, with an output voltage of 380V/220V. If the leakage current to the ground exceeds 30mA, the power supply will be cut off; The electrical control adopts a DC 24V power supply and is equipped with overvoltage protection to prevent accidental operation and damage to the equipment.
