I. Overview
The Hydraulic and Pneumatic PLC Control Comprehensive Training Device is a product developed by our company based on the curriculum requirements of gas, electrical, and hydraulic control for electromechanical integration in colleges and universities. It leverages the advantages of our hydraulic PLC and pneumatic PLC control training equipment, utilizes an open-type comprehensive experimental bench structure, and incorporates extensive feedback from experts, professors, and teachers. It has been continuously innovated and improved. It is an ideal comprehensive training device that integrates pneumatic control technology, hydraulic transmission control technology, and PLC control. The training allows students to intuitively and emotionally compare and understand the characteristics, features, and advantages and disadvantages of gas, electricity, and hydraulic systems.
Hydraulic test components are made of transparent organic materials, offering clear and intuitive visibility. They facilitate understanding the structure, performance, and applications of dozens of common hydraulic components. Users can master the working process and principles of several basic experimental circuits. During experiments, assembling the experimental circuits is quick and convenient. The pneumatic and hydraulic training units are equipped with two independent relay controls and two independent PLC controls, making them simple and practical.
Section II: Training Table Composition
The practical training system features a "two-in-one" double-sided structure, where one experimental table can accommodate two groups of four students for separate pneumatic and hydraulic experiments. It allows for simultaneous double-sided pneumatic-hydraulic comprehensive experiments, optimizing resource sharing and enhancing the performance-to-price ratio of the product. The overall structure is simple and highly practical.
This training bench is constructed of iron with a double-layer matte textured powder coating. It is aesthetically pleasing, sturdy, durable, and easy to operate. The basic configuration includes: 1 set of pneumatic training components; 1 set of pneumatic PLC control modules; 1 low-noise air compressor; 1 set of hydraulic training components; 1 set of hydraulic PLC control modules; and 1 hydraulic pump station. (Computers are provided separately according to the school's requirements.)
This training system utilizes a dedicated, independent hydraulic test pump station, equipped with a DC motor variable speed control system and oil pressure adjustment function, allowing for the setting of safe working pressure for the output pressure oil. It is fitted with all standard hydraulic components: each hydraulic component comes with an installation base plate, enabling easy and flexible placement of the hydraulic components on the aluminum alloy profile panel (with T-groove aluminum alloy profile structure). The oil line connections use quick-release fittings, making assembly and disassembly easy and oil-tight.
This training equipment set allows for both independent and integrated experiments. It can be used for separate studies of basic pneumatic and hydraulic control circuits and their applications, as well as for comprehensive experiments involving coordinated operations: such as gas-electric control, gas-liquid control, electric-liquid control, and integrated gas-electric-liquid control.
