(2) The system facilitates the examination of students' ability to select accessories, disassembly and assembly capabilities, device operation, task completion, etc., and has corresponding judgment standards and methods.
(3) The system provides sufficient optional accessories, disassembly and assembly tools, equipment for inspection and operation, etc.
(4) Components that are often disassembled and assembled must be solid and durable, easy for students to use for a long time, and can provide updated equipment.
2. System functions
(1) Reading of flow charts.
(2) Able to accurately fill in the material list of specifications, models, quantities, etc. of pipes, pipe fittings, valves, and instruments required for pipeline installation based on the fluid transportation flow chart provided.
(3) Able to correctly receive the required materials according to the materials list.
(4) Be able to accurately list the tools and consumables required to assemble the pipeline and correctly receive the tools and consumables.
(5) Ability to assemble pipelines.
(6) Ability to perform pressure testing of pipelines.
(7) Ability to dismantle pipelines.
(8) Ability to comply with safety regulations during pipeline disassembly and assembly.
3. Pipeline disassembly and assembly tr*ning content
(1) Pipeline assembly
(a) Processing of pipe mouth threads and use of die.
(b) Install the pipeline according to the pipeline schematic diagram. During installation, ensure that the horizontal and vertical directions are not greater than 15 mm and the vertical deviation is not greater than 10 mm.
(c) When connecting flanges and threads, the parallelism and concentricity of each p*r of flanges must meet the requirements. When joining threads, the winding direction of the raw material tape must be correct and the thickness must be appropriate. When the threads and pipe fittings are engaged, they must be aligned and aligned, and the tightening force must be moderate.
(d) Installation of the valve: Before installing the valve, clean the inside and close it before installing. For directional valves, they must match the flow direction of the medium. The installed valve handwheel must be positioned for easy operation.
(e) The installation of flow meter, pressure gauge and filter shall be carried out according to the specific installation requirements. Pay attention to the flow direction, and the location of the scale should be convenient for reading.
(2) Hydraulic pressure test:
Be able to use a hand-operated pressure test pump and complete the pressure test operation according to the required pressure test procedures. There should be no leakage at all joints of the pipeline under the specified pressure and within the specified time.
(3) Pipeline disassembly
can be carried out in order, usually from top to bottom, instruments first and then valves. Pipe fittings and instruments must not be damaged during the disassembly process. Disassembled pipes, fittings, valves and instruments should be sorted and put away.
4. System configuration list
The system consists of the following five parts: 1. Pipeline disassembly and assembly object system; 2. Pipeline disassembly and assembly tools (including pressure test and leak detection equipment) 3. Pipeline disassembly and assembly shelves; 4. Pipeline disassembly and assembly racks Equipment parts.
5. Mechanical tr*ning safety education virtual simulation software: This software is developed based on unity3d. The software adopts the form of three-dimensional roaming, which can control movement through the keyboard and the mouse to control the lens direction. It is equipped with mechanical safety distance experiments, mechanical safety protection device experiments, and mechanical safety experiments. Basic assessment of protective design. When the experiment is in progress, the three-dimensional roaming screen uses arrows and footprints to prompt the user to move to the experimental location. The circle around the mechanical object shows the working radius. The experimental process is accompanied by a dialog box reminder of the three-dimensional robot.
A. The content of the mechanical safety distance experiment includes the safety distance experiment to prevent upper and lower limbs from touching the danger zone (divided into two fence heights and opening sizes). After selecting to enter, GB23821-2009 "Mechanical Safety to Prevent Upper and Lower Limbs from Touching the Danger Zone" pops up in front of the camera. "Safe Distance" requirements, error demonstration: The experimental process is that after the human body enters the working radius of the mechanical object and is injured, the red screen and voice prompts that the human body has received mechanical damage, and returns to the original position and conducts the next experiment. The last step is the correct approach.
B. Mechanical safety protection device experiments are divided into safety interlock switches, safety light curt*ns, safety mats, safety laser scanners and other protection device experiments. Optional categories (safety input, safety control, safety output, others), manufacturers, products List (safety interlock switch, safety light curt*n, safety mat, safety laser scanner, safety controller, safety relay, safety guardr*l). There is a blue flashing frame reminder at the installation location. Experimental process: select the safety guardr*l and install it, select the safety interlock switch (or select the safety light curt*n, safety mat, safety laser scanner) and install it, select the safety controller and install it in the electrical control box , select the safety relay and install it in the electrical control box, click the start button on the electrical control box. If you enter a dangerous area, the system will sound an alarm and the mechanical object will stop working. Select the reset button on the electrical control box to stop.
C. The basic assessment of mechanical safety protection design requires the completion of the installation of the mechanical safety system, and the correct installation of safety guardr*ls, safety interlock switches, safety light curt*ns, safety mats, safety laser scanners, safety controllers, safety relays, 24V power supplies, signal lights and Emergency stop button. The assessment is divided into ten assessment points. Some assessment points have 3 options, which are freely chosen by the students. After selecting the final 10 assessment points, submit for confirmation, and the system will automatically obt*n the total score and the score of each assessment point. .
D. The software must be on the same platform as a whole and must not be displayed as separate resources.
At the same time, the VR installation package of this software is provided to customers to facilitate users to expand into VR experiments. VR equipment and software installation and debugging are not required.
