4. Hot water pump: allowable operating temperature: ≤105℃; rated flow: 1.5m3/h; head: 10m.
5. Cold and hot medium flow measurement: rotor flowmeter is used, range: 16-160L/h.
6. Raw water tank: 304 st*nless steel, volume: 80L (the cold water tank is sealed with a cover to prevent dust from falling, and is equipped with a liquid level display device; the water tank inlet is equipped with a float valve to ensure the constant water level of the water tank).
7. Hot water tank: 304 st*nless steel, volume: 60L (the hot water tank is sealed with a cover, independent of the cold water tank, and equipped with a liquid level display device).
8. Temperature measurement: Temperature sensor : Class A Pt100; resolution 0.1℃. 8-point universal signal digital display inspection instrument.
9. 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.
10. Dimensions: 1500×500×1700mm, the appearance is a st*nless steel movable bracket with double brake wheels.
11. Virtual simulation software for electrical installation of building buildings and intelligent buildings 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, as follows: A. Wet alarm system 1. System overview: Overview of wet alarm system 2. Equipment recognition: It has the best viewing angle, equipment det*ls (displaying the introduction or parameters of the equipment), exercises (6 built-in 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 regulators, flow switches, terminal water testing devices, dr*nage facilities, water pump connectors, hydraulic alarms, delays, wet alarms, butterfly valves, check valves, fire pumps, safety pressure regulators, and fire water tanks. 3. Principle display: Display the working principle of the wet alarm system, 3D animation demonstration, and semi-transparent 3D models to see the internal water flow. 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 a practice module (built-in 3 multiple-choice questions, with prompts for correct and incorrect choices) 4. Design and 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, escaping from the burning room within a limited time, and wrong choices will directly enter the score interface
