Main features. 

1. The system all adopts standard industrial hydraulic components: the use of safe and reliable, close to industrialization. All hydraulic valves are used in the international advanced technology hydraulic components, performance parameters in full compliance with the requirements of the syllabus, and fully in line with industrial application standards;

2. Experimental circuit plug and play: experimental trainees can quickly understand the function of the experimental bench, quickly master the operating skills, and quickly complete the experimental operation. Connection method adopts quick-change joints, each joint is equipped with a one-way valve with self-locking structure (even if the joints are not connected and fall off in the course of the experiment, there will be no pressure oil sprayed out to ensure the safety of the experiment), the internal sealing material utilizes the latest international sealing material - PTFE sealing ring, replacing the traditional nitrile material, which solves the problem of oil leakage that has not yet been overcome by the majority of other manufacturers. The internal sealing material utilizes the latest international sealing material - PTFE sealing ring instead of the traditional nitrile material, which solves the problem of oil leakage that most other manufacturers have not yet overcome and ensures the cleanliness of the experimental process;

3. Diversified experimental control: the experimental circuit can use mechanical control, traditional relay control, advanced PLC automatic control and other control technologies, so that the students can have an all-round, multi-level in-depth understanding of the control of the hydraulic system diversified, so as to exercise the students' flexible application capabilities;

Experimental equipment has a very expandable space: experimental configuration program can be configured according to specific requirements, but also on the experimental equipment to increase components and other control methods to enhance the function of the experimental bench, components are standardized connectors, the late addition of new components are compatible with the experimental bench;

5. Programmable logic controller (PLC) can communicate with the PC: to realize the electrical automation control, online programming monitoring and fault detection, as well as the use of PC and PLC hydraulic control system for in-depth secondary development;

6. mobile modular design of the experimental bench: in the design of the experimental bench is not only a combination of ergonomics, international popular design concepts, product features and other factors, as far as possible, the experimental bench beautiful and lightweight, in line with the aesthetic requirements, but also on the reliability of the experimental bench, safety, service life and so on is also unambiguous, to break the traditional design concepts;

7. Rich configuration simulation software: provides up to 20 simulation/monitoring of commonly used circuits, circuits can be monitored to each of the valve core action, fluid flow, pressure, actuator action, as well as PLC I/O interface input/output situation. All kinds of monitoring conditions are visualized on the monitoring screen in the form of picture color distinction/text, which is very intuitive and clear;

8. Equipped with advanced high-precision measuring instruments: high stability data measuring instruments, instead of traditional measuring tools, easy to use, accurate and reliable measurement;

9. Stable and reliable data acquisition system: using imported 12 precision 8-channel I/O AD data acquisition card, to ensure that the experimental data is accurate, interference is small, and stability is higher than other products of the same type; I/O channels can be expanded according to the needs of self-expansion, easy and convenient to operate, the software adopts the original system with independent intellectual property rights and stable performance, according to the needs of real-time curves, generating reports, generating X-Y curve, data accuracy and system stability, and the system is stable. Y curve, accurate data and stable system;

10. excellent hydraulic oil supply system: hydraulic oil pump using flange mounting, greatly reducing the noise of the work operation, and the hydraulic oil supply system on the basis of the conventional increase in safety valves, etc., to play a secondary role in protection, to ensure the safety of the experiment;

11. High safety level: the design of the experimental bench in full accordance with national safety standards, all electrical controls are grounding protection, overload protection, short circuit protection, leakage protection and other functions, with a high degree of safety performance.
