I. Overview

YYG type engineering hydraulic PLC comprehensive control experiment system is based on the syllabus requirements for gas, electricity and hydraulic control of mechanical and electrical integration in colleges and universities. Based on our company's patented product YY-18 transparent hydraulic transmission demonstration system, the hydraulic PLC Control the advantages of experimental equipment, using an open comprehensive experimental bench structure, extensively soliciting the opinions of experts and professors and teachers, developed through continuous innovation and improvement. It is a comprehensive experimental equipment integrating the current hydraulic transmission control technology and PLC programmable controller control technology. During the experiment, students can make intuitive and perceptual comparisons and understand the characteristics, features, advantages and disadvantages of electricity and fluid. Cultivate students' practical ability, design ability, comprehensive application ability and innovation ability.
Hydraulic experimental components mainly use Beijing Huade Hydraulics, Tianjin Tianer Hydraulics, Keyuda Hydraulics and other products. It is easy to understand the structure, performance and application of dozens of commonly used hydraulic components. Master the working process and principles of dozens of basic experimental circuits. During the experiment, assembling the experimental circuit is fast and convenient. At the same time, it is equipped with an independent relay control unit for electrical control, which is simple and practical. By comparing with PLC, you can deepen your understanding and mastery of PLC programmable controllers.

Features

(1) This experimental system uses a steel spray experimental table and a highly wear-resistant table board. The whole experimental bench has a reasonable structure and beautiful appearance. One experimental table can be used for multiple students to conduct comprehensive hydraulic experiments to optimize shared resources and improve the price-performance ratio of products. Large operating area, convenient operation, beautiful appearance, sturdy and durable.
(2) The special "T" aluminum alloy slot plate and "T" special nut are used for installation and fixing. The hydraulic components can be positioned and installed at will in the aluminum alloy slot plate, which is particularly suitable for the installation of the hydraulic circuit of industrial hydraulic components. Disassembly experiment. There is an oil tank under the "T" aluminum alloy tank plate. If students spill oil during the experiment, it will directly flow to the oil tank without contaminating the experimental bench, ensuring the cleanness of the experimental process.
(3) Good sealing performance: The quick-locking joint developed by our company is designed and manufactured. The joint is designed and produced in accordance with the universal joint standard, and the oil pipe is clamped by screw connection. Compared with the universal joint, it has a beautiful structure, simple operation, large tightening force, good connection performance, good sealing performance, and can withstand large pressures, does not leak oil, and works stably. If the user adds other hydraulic components to the experimental equipment, it can be used. It is suitable for students to do performance principle structure experiment.
(4) The surface of the component fixing board is printed, which corresponds to the components one-on-one, so that students can understand all the components of the experimental table and quickly find the required components.
(5) Adopting programmable and microcomputer communication: realizing electrical automation control, enabling prior editing and fault detection.
(6) This set of experimental equipment can be used to independently perform the corresponding basic circuit of hydraulic control and its application experiments, as well as PLC programming and control experiments; at the same time, it can also comprehensively perform mutually compatible experiments: such as to achieve electro-hydraulic control.

(3) Electrical control devices (1) DC power supply input voltage: AC 24V 50Hz
Output: DC 24V / 2.5A
AC 220V
(220V output is used to control the solenoid valve in our hydraulic products)
(2) Relay control unit The relay control unit has two sets of functions with the same function and independent control signals to control the corresponding solenoid valve groups. Each group of control circuits has reversing 1, reversing 2, and stop buttons; left and right normally open pneumatic input signal jacks, left and right normally closed stop input signal jacks; and controls the corresponding solenoid valve group output 1, output 2, respectively.
When using the relay unit, you only need to connect the DC power supply, input and output to the corresponding position, and then you can perform the control operation (make sure the line connection is correct). And a relay contact conversion module is attached to expand the contact switch signal.
(3) Relay contact conversion module The relay contact conversion module has six groups of independent relay contact conversion control circuits with the same functions.
Use the test button of each group as the master button, and provide two normally open start signals and two normally closed signals to the relay control module at the same time. Use the input jacks of each group to convert and expand the contact switch signals. And can input three-wire sensor signal (positive power, negative power, signal).

(4) PLC control module
The PLC control module mainly includes a PLC central control module, a PLC electrical input module, and a PLC electrical output module.
Our company uses Japan's Mitsubishi FX1s-14MR type programmable controller and has designed a universal PLC control program. It has three groups of functional circuits. The control of the PLC electrical input unit is divided into three independent control sections: control group one, control group two, and extended control. Corresponding control outputs: solenoid valve group 1, solenoid valve group 2 and solenoid valve group 3. The PLC electrical output unit consists of two parts and is powered by a DC voltage unit (DC 24V). When using, connect the parts by connecting cables.
