JG-YY01 PLC control transparent hydraulic transmission demonstration system training device

I. Product Introduction In order to adapt to the development of various fields as soon as possible, technical workers, technicians, and engineers who have mastered the basic knowledge and practical skills of hydraulic transmission in Dali have been trained to transport to the various fronts of socialist construction. According to the requirements of textbooks such as "Hydraulic Transmission", "Hydraulic Principles", "Machine Basics", and other domestic hydraulic components, and referring to foreign advanced technology, after years of hard exploration, we take theory as the basis and experiment as the means. Adopting high-precision processing technology to overcome a series of practical difficulties of transparent organic plastics that are thermoplastic, easily deformed, and poor in mechanical strength, and the surface finish of hydraulic components and high structural accuracy requirements, the DB-YY01 transparent hydraulic transmission demonstration system was successfully developed .
Various machines have various requirements for hydraulic transmission. Generally, they are composed of basic function circuits such as directional control circuit, pressure control circuit, speed control circuit, and sequence control circuit. The experimental screen of this experimental platform is made of 1.0mm cold-rolled steel plate. Each hydraulic component adopts a transition base plate. The overall appearance is beautiful, the structure is durable, and the operation is convenient. This demonstration system demonstrates eighteen basic control loops of the above four basic functions (expanded experiments can reach 60), so that students can familiarize themselves with the structure, performance and use of more than twenty commonly used hydraulic components, and master more than ten This kind of basic circuit work process and principle, improve the ability of students to troubleshoot and solve problems, get inspired in the experimental demonstration, and arouse interest. Use it to experiment with other oil circuits within the tolerances of various components provided by this product ( (Figure design, graduation design).
The hydraulic test bench products refer to the characteristics of domestic hydraulic components and are more suitable for domestic teaching requirements. The system uses transparent hydraulic components, a combined card slot structure, a movable oil circuit joint, and a general electric circuit. With the use of attached tool materials and referring to experimental instructions, various common hydraulic transmission controls, experiments and tests can be conveniently performed. Students understand the internal principle, structure and working process of oil circuits and hydraulic components, and are ideal equipment for teaching hydraulic transmission.


Second, the main technical indicators
1. Power supply: 220V 50Hz (mains power)
2. Dimensions of the demonstration stand: 1500mm (length) × 700mm (width) × 1700mm (height).
3. PLC programmable controller: Panasonic (CPU224 relay output mode).
