JGYY-18F Four -in- one Hydraulic Transmission Demonstration System Experiment Bench <br /> The four-in-one hydraulic transmission demonstration system patented technology is the latest scientific and technological achievement for modernization teaching of hydraulic transmission courses, and it has filled technical schools, technical secondary schools and colleges National blank of school of hydraulic transmission transparent teaching equipment. The hydraulic transmission has the characteristics of light weight, high power, simple structure, flexible layout, and convenient control. The speed, torque, and power can be adjusted steplessly. It can quickly change direction and speed. The speed range is wide, the speed is good, and the work is stable. , Low noise, components have achieved a series of advantages such as serialization, standardization, and generalization. With the development of science and technology, hydraulic transmission, as a transmission method that can transmit power and control, has been increasingly widely used in medical, scientific and technological, Military, industrial automation production, start-up, transportation, mining, construction, aviation and other fields. In order to adapt to the teaching content of multiple hydraulic circuits in a short class time. Simultaneously compare and demonstrate the working principle of multiple different oil circuits. Moreover, the necessary procedures are required for the installation and commissioning of the oil circuit system and do not take up class teaching time. There must be multiple devices working at the same time. At the same time, when the YY-18 transparent hydraulic demonstration system performs a combined experiment on one of the experimental circuits, 80% of the transparent hydraulic components are left idle. The YY-18F "four-in-one" transparent hydraulic transmission demonstration system is adding and guaranteeing experimental items. Under the premise of function and function, according to the principle of doing different demonstration experiments in the same lesson, the transparent hydraulic components are effectively used to optimize the combination, and the performance price of the product is reduced by 40%. At the same time, new hydraulic components have been added: double-acting vane pump, cycloidal rotor pump, pilot-operated relief valve, Y-type three-position four-way electromagnetic directional valve, solid double-rod cylinder, hollow double-rod cylinder, oil Plate ... New hydraulic components: vane pump, cycloidal pump, pilot operated relief valve, hollow (solid) double-outlet cylinder ...

Features
1. It is possible to compare different experimental circuits to deepen the understanding of the principle of hydraulic circuits.
