Release time：2024-06-12 17:30viewed：times
Technical parameters:
1. Input power: single-phase AC220V±10% 50Hz, power 1.5KW.
2. The test piece is a copper tube with a diameter of φ20mm and a length of 300mm, placed in the *r duct. The fan power is 150W and the *r volume is 500 m3/h.
3. Heaters are installed at both ends of the tube, and their power is controlled by the voltage regulator. A movable thermocouple temperature measuring head is installed in the tube to measure the temperature distribution of the copper tube along the length of the tube.
4. Temperature measurement: The measurement system is equipped with an intelligent temperature control instrument (PID temperature control, accuracy ±0.2℃) and a high-precision PID voltage regulation module circuit.
5. Dimensions: 500×400×600mm, with a st*nless steel bracket.
6. Virtual simulation software for electrical installation of building and intelligent building Based on unity3d design, users can choose different sizes of interactive interfaces according to computer configuration, and can choose six levels of image quality. The model in the software can be rotated 360°, enlarged, reduced, and translated. There are assistant prompts during the use of the software, the contents are as follows: A. Wet alarm system 1. System overview: Overview of wet alarm system 2. Equipment recognition: It is equipped with the best viewing angle, equipment det*ls (displaying the introduction or parameters of the equipment), exercises (built-in 6 multiple-choice questions, with prompts for correct and wrong choices), and schematic diagrams (you can enter the equipment from the schematic diagram). The equipment includes: sprinklers, water flow indicators, signal butterfly valves, exhaust valves, fire alarm controls, high-pressure gauges, high-level water tanks, Wia control cabinets, pressure-stabilizing tanks, flow switches, terminal water testing devices, dr*nage facilities, water pump connectors, hydraulic alarms, time delays, wet alarms, butterfly valves, check valves, fire pumps, safety pressure-stabilizing valves, and fire water tanks. 3. Principle display: Display the working principle of the wet alarm system, 3D animation demonstration, and semi-transparent 3D models, so that the internal water flow can be seen. Equipped with practice module (built-in 4 multiple-choice questions, with prompts for correct and wrong choices) 4. Design layout: There are multiple-choice questions and calculation questions, each of which is scored, and the correct answer and score will be displayed after submission B. Gas fire extinguishing system 1. System overview: Overview of gas fire extinguishing system 2. Equipment cognition: It is equipped with the best viewing angle, equipment det*ls (displaying the introduction or parameters of the equipment), practice (built-in 8 multiple-choice questions, with prompts for correct and wrong choices), schematic diagram (you can enter the equipment from the schematic diagram). The equipment includes: nozzle, HFC-227 storage bottle, bottle head valve, heptafluoropropane check valve, high-pressure hose, gas check valve, safety valve, weighing alarm, electromagnetic starter, selection valve, smoke alarm, fire alarm controller. 3. Principle display: Display the working principle of the gas fire extinguishing system, 3D animation demonstration, 3D model is semi-transparent, and the internal gas can be seen. Equipped with practice module (3 multiple-choice questions built in, with prompts for correct and incorrect choices) 4. Design layout: There are 6 multiple-choice questions, each with a score, and the correct answer and score will be displayed after submission C. Escape drill: Teaching in the form of fun games, escape from the burning room within a limited time, and wrong choices will directly enter the score interface. Experimental purpose: 1. Solve the heat conduction characteristics of the extended body with convective heat transfer conditions (such as the temperature distribution along the axis, the convective heat transfer coefficient, the position of the minimum excess temperature Xmin, etc.). 2. Understand the method of thermocouple temperature measurement. M*n configuration: plexiglass duct, heater, high temperature voltmeter, heating tube (test piece), displacement ruler, induced draft fan, thermocouple, potentiometer, st*nless steel stand and control panel, etc.
