The hydraulic front hanging mechanical training desk, the experimental control of the front hanging hydraulic system experimental desk is manual control and automatic control.

Hydraulic reach stacker is a machine used for cont*ner loading and unloading . It is widely used in ports, r*lways and highway transportation operations. At present, almost all small and medium-sized reach stackers use hydraulic transmission. Hydraulic reach stackers have the advantages of small size, light weight, flexible and convenient operation, large lifting force, easy to implement overload protection and indoor control. In recent years, the application of high-tech microelectronics technology in hydraulic technology has made the comprehensive technical level of engineering machinery , construction machinery and transportation machinery higher and higher, improving the reliability, operational safety, comfort and service life of these machinery. More adaptable.

2) Learning and using PLC programming software;
3) Communication and online debugging between PLC and computer;
4) Application of PLC in hydraulic transmission control and optimization of control schemes.
3. Performance and Characteristics
1. The experimental bench is made of cold-rolled steel plates (and has undergone plastic spraying and anti-corrosion treatment). It has a desktop structure and integrated control and operation.
2. The electrical operation control is bottom-mounted, and the hydraulic station is placed in the m*n cabinet of the hydraulic table. The overall structure is compact and coordinated, the layout is beautiful and generous, and it is highly practical and can be used for experiments by 4-6 people.
3. The reach stacker machine has an all-metal structure that is scaled down to the actual scale. During the experiment, the hydraulic system was started to operate the machine according to the experimental requirements.
4. The reach stacker machinery is made according to the structure and reduced scale of the actual object, which can truly reflect the actual working conditions of the machinery, allowing students to deeply understand the structure and working principles of each component of the mechanism during the experiment.
5. Experimental control adopts two methods: manual control and automatic control.
6. The experimental components adopt pressure-resistant hoses, and the pressure can reach 25Mpa.
7. With three-phase leakage protection, the output voltage is 380V/220V. If the leakage current to the ground exceeds 30mA, the power supply will be cut off. The electrical control adopts DC 24V power supply and has overvoltage protection to prevent damage to the equipment due to misoperation.
8. Hydraulic and pneumatic transmission design and control virtual simulation software: This software is developed based on unity3d. The software adopts the form of three-dimensional roaming. Movement can be controlled by the keyboard and the lens direction can be controlled by the mouse. The interface is equipped with home page, help, full screen, component recognition, and loop. Construction, key component testing, typical system testing interface.
1. Component identification adopts the form of automatic playback, which introduces the m*lbox, liquid level gauge, oil pump unit on the equipment (the pop-up hydraulic symbols, principles and introduction are introduced here, click OK to enter the next introduction), valve frame, and pressure gauge. , sensors , etc.
2. The disassembly and assembly of components is divided into learning mode and assessment mode. There are built-in electromagnetic reversing valves, plate relief valves, plunger pumps, filter valves, and electro-hydraulic servo valves. In the learning mode, the disassembly sequence is prompted and highlighted. There are no prompts for disassembly and installation in assessment mode. If the disassembly and assembly sequence is wrong, the next step of disassembly and assembly will no longer be possible. The toolbar is equipped with draggable seals, pumps, valves, oil filters, hex wrenches, pipe wrenches, adjustable wrenches, dead wrenches, and M5 screws.
3. The hydraulic components are equipped with one-way valve (hydraulic control, poppet valve core, ball valve core), m*n structure of the reversing valve (O type, Y type, H type), hydraulic cylinder (assembled plunger, double-acting single outlet rod) , double-action double-output rod, single-action double-output rod, single-action single-output rod), etc. Each construction experiment adopts a graphical method and is constructed by dragging the set graphics. In the graphics library There are confusing graphics.
4. Hydraulic selection is based on the hydraulic schematic diagram, and then selects the nominal displacement of the pump (12 items, including 11 confusing items) and pressure level (5 items, including 4 confusing items), and the selection of the solenoid relief valve (3 specifications, 3 pressure levels, and 3 flow levels, all of which have confusing items), oil filter selection (multiple choices include confusing items), servo valve selection (multiple choices include confusing items), and the wrong selection system will Automatically prompt the correct answer. After selecting, drag the corresponding tool to the highlighted area according to the prompt.
5. Circuit inspection is done by selecting the correct accessories, including the selection of sealing rings, checking valve switches, etc. Then proceed to the next step to turn on the machine. Follow the prompts to turn on the machine. After turning on the machine, enter the monitoring interface. Turn on the equipment one by one according to the prompts. The prompts are in the form of text and button highlighting.
6. Hydraulic cylinder pressure test Enter the experiment through the test button on the background interface and gradually analyze To start friction test, start friction force, parameter setting, start test, draw curve, stop test.
7. Typical system tests are divided into trial operation, stage response test and frequency response test. The above tests are all conducted through the background monitoring interface.
