. To understand the changing rules and test methods of pressure and flow of *rflow in the nozzle.
M*n configuration:
nozzle body, bracket, organic glass converging nozzle, organic glass converging and expanding nozzle, pressure regulator, 2 vacuum pressure gauges, orifice flowmeter, U-type differential pressure gauge, regulating valve, vacuum pump (prepared by the user), pressure probe, probe displacement device, scale ruler, inlet collector, st*nless steel stand, etc.
Technical parameters:
1. Input power: three-phase AC380V±10% 50Hz, power 5.5KW.
2. Pressure measurement uses -0.1-0MPa precision vacuum gauge, accuracy 0.4 level. Flow measurement uses low Reynolds number conical orifice flowmeter, throat diameter φ20mm.
3. Spray needle diameter φ4±0.2mm. Pressure regulator: diameter φ400mm, *r inlet diameter Φ63mm, *r outlet diameter Φ57mm.
4. Dimensions: 2000×500×1000mm, the appearance is a st*nless steel bracket.
5. User-provided instruments, vacuum pump: exhaust rate: 54L/s, ultimate vacuum: 1.33 Pa, rate: 385r/min, power: 5.5KW.
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, 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 (built-in 6 multiple-choice questions, with prompts for correct and wrong choices), schematic diagram (you can enter the device from the schematic diagram). Equipment includes: sprinkler, water flow indicator, signal butterfly valve, exhaust valve, fire alarm control, high pressure gauge, high-level water tank, Weiya control cabinet, pressure regulating tank, flow switch, terminal water test device, dr*nage facilities, water pump connector, hydraulic alarm, delay, wet alarm, butterfly valve, check valve, fire pump, safety pressure regulating valve, fire water pool. 3. Principle display: Display the working principle of the wet alarm system, 3D animation demonstration, 3D model is semi-transparent, and the internal water flow can be seen. Equipped with exercise module (4 built-in multiple-choice questions, both correct and wrong choices are prompted) 4. Design layout: There are multiple-choice questions and calculation questions, each question is scored, and the correct answer and score are 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), exercises (8 built-in multiple-choice questions, both correct and wrong choices are prompted), and schematic diagram (you can enter the equipment from the schematic diagram). Equipment includes: nozzle, HFC-227 storage bottle, bottle head valve, HFC-227 one-way valve, high-pressure hose, gas one-way valve, safety valve, weighing alarm, electromagnetic starter, selector valve, smoke alarm, fire alarm controller. 3. Principle display: Demonstrate 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 built-in multiple-choice questions, with prompts for correct and wrong choices) 4. Design layout: There are 6 multiple-choice questions, each with scores, 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.
