9. The frame and tabletop are made of 304 st*nless steel, with compact structure, beautiful appearance and easy operation.
10. Overall dimensions: 1600×500×1700mm (length×width×height), the frame is removable, with casters and locking feet.
11. Virtual simulation software for electrical installation of building buildings and smart buildings. Based on unity3d design, users can choose different interactive interface sizes according to computer configuration, and can choose from six image quality levels. The model in the software can be rotated 360°, enlarged, reduced, and translated. There are assistant prompts during the use of the software, and the content is as follows: A. Wet alarm system 1. System overview: Overview of wet alarm system 2. Equipment awareness: equipped with the best viewing angle, equipment det*ls (displaying the introduction or parameters of the equipment), and exercises (Built-in 6 multiple-choice questions, prompts for correct and incorrect choices), schematic diagram (can be entered into the device from the schematic diagram). Equipment includes: nozzle, water flow indicator, signal butterfly valve, exhaust valve, fire alarm control, high pipe pressure gauge, high water tank, Wia control cabinet, pressure stabilizing tank, flow switch, terminal water testing device, dr*nage facilities, water pump connection alarms, hydraulic alarms, delayers, wet alarms, butterfly valves, check valves, fire pumps, safety pressure regulators, and fire pools. 3. Principle display: Show the working principle of the wet alarm system, three-dimensional animation demonstration, the three-dimensional model is translucent, and the internal water flow can be seen. Equipped with a practice module (built-in 4 multiple-choice questions, with prompts for correct and incorrect choices) 4. Design layout: There are multiple-choice questions and calculation questions, each question is scored, and the correct answer and score will be displayed after submission B.

Principle display: Show the working principle of the gas fire extinguishing system, three-dimensional animation demonstration, the three-dimensional model is translucent, and the internal gas can be seen. Equipped with a practice module (built-in 3 multiple-choice questions, with prompts for both correct and incorrect choices) 4. Design and layout: There are 6 multiple-choice questions, each question is scored, and the correct answer and score will be displayed after submission. C. Escape drill: adopted Teaching is conducted in the form of a fun game. Escape from the burning room within a limited time. If you make a wrong choice, you will directly enter the score interface . Experimental purpose: 1. Understand the principle of the Venturi flow meter and its experimental device. 2. Determine the flow coefficient μ value of the Venturi flow meter through the measured relationship curve between pressure difference and flow rate. 3. It can quantitatively measure pipeline flow and give the correlation between flow coefficient and Re number. M*n configuration: organic glass constant water tank, water pump, venturi tube, pressure measuring frame, moving scale, water storage tank, metering water tank, scale scale, stopwatch, glass thermometer, connecting pipe valve, st*nless steel bracket.
