1、 Product Introduction
In order to adapt to the development of various fields as soon as possible, cultivate a large number of technical workers, technicians, engineers who master the basic knowledge and practical operation skills of hydraulic transmission, and transport them to various fronts of socialist construction. Based on the requirements of textbooks such as Hydraulic Transmission, Hydraulic Principles, and Mechanical Foundations, as well as the characteristics of hydraulic components in China, and with reference to advanced foreign technologies, our company has made efforts to explore for many years. Based on theory and through experiments, we have adopted high-precision processing technology to overcome the thermoplastic nature of transparent organic plastics, which are prone to deformation, poor mechanical strength, and surface smoothness of hydraulic components, A series of practical difficulties with high structural accuracy requirements have been overcome. A transparent hydraulic transmission experimental platform has been successfully developed. In order to improve space utilization, a double-sided experimental platform has been specially designed to reduce costs and improve efficiency.
The requirements of various machinery for hydraulic transmission are diverse, generally composed of basic functional circuits such as direction control circuit, pressure control circuit, speed control circuit, sequence control circuit, etc. The main frame of the experimental platform is refined from 1.0mm cold-rolled steel plate, with a painted surface that is aesthetically pleasing and sturdy. The bottom is equipped with four high-quality axial universal wheels, making it easy to move. The bottom of the cabinet is divided into two parts. The left side is used to place the hydraulic pump station, and the right side is a storage cabinet used to store transparent hydraulic components.
Each hydraulic component adopts a sky blue snap card type transition bottom plate, which has an overall beautiful and generous appearance, a sturdy and durable structure, and convenient operation. This demonstration system enables students to familiarize themselves with the structures, performance, and applications of over 20 commonly used hydraulic components, master the working processes and principles of more than ten basic circuits, and improve their ability to handle faults and solve problems through experimental demonstrations of 18 basic control circuits with the above four basic functions (up to 60 extended experiments). Through these demonstrations, students are inspired and interested, It can be used to conduct extended experiments on other oil circuits within the tolerance range of various components provided by this product (such as oil circuit design and graduation design).
This hydraulic test bench product references the characteristics of domestic hydraulic components, making it more suitable for teaching requirements in China. The system adopts transparent hydraulic components, a combination card slot structure, movable oil circuit joints, and general electrical circuits. By using attached tool materials and referring to experimental manuals, various commonly used hydraulic transmission control experiments can be conveniently carried out, allowing students to understand the principles, structures, and working processes of oil circuits and hydraulic components. It is an ideal equipment for hydraulic transmission teaching.
