Heat exchangers are very commonly used equipment in chemical companies. It is very necessary for company employees to understand the structure, learn m*ntenance, disassembly, etc. Therefore, we selected a typical tube heat exchanger to help students master the internal structure, disassembly and assembly operations, pressure test and leak detection system operations of a typical tube heat exchanger, as well as understand and master the high-pressure cleaning and column operation of a tube heat exchanger. Knowledge on inspection and m*ntenance procedures such as pipe plugging and leakage.
1. System composition
The heat exchanger disassembly, assembly and rep*r tr*ning tr*ning device consists of a tubular heat exchanger, disassembly and assembly tools, leak plugging tools, shelves, disassembly and assembly tables, trolleys, etc.
2. System functions
1. To enable students to understand and master the structure of a typical fixed tube plate type tube heat exchanger in chemical industry equipment, the operation process of disassembly, assembly and replacement of heads and gaskets, and the common sense of inspection during the use of pressure vessels. At the same time, graphic display boards for U-tube heat exchangers, floating head heat exchangers, and finned tube heat exchangers are provided to help students understand the internal structures of various types of heat exchangers.
2. Examine students’ familiarity with the internal structure of heat exchangers and their knowledge and skills in chemical equipment safety inspection.
3. Let students understand the common methods of heat exchanger cleaning: mechanical treatment, water washing and chemical cleaning.
4. Enable students to master the safe operating procedures for pressure testing, leak testing, and leak plugging on the tube side and shell side of tube-and-tube heat exchangers.
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.
