Purpose of the experiment:
Accurately measure the *r volume through the *r volume measuring box, calibrate the flow measurement of circular pipes and giant pipes, and also perform measurements on pipes of different shapes and other methods of measuring *r volume, such as wind speed method and dynamic pressure method. Relative comparison and error comparison analysis. Exhaust hood performance test can be done. Measuring instruments with *r flow rates less than 1500 m3/h can be studied.
M*n configuration:
fan box; standard *r volume measurement box; standard flow nozzle; frequency converter for fan; *r volume adjustment valve; replaceable *r duct (rectangular tube, round tube); umbrella-shaped exhaust hood.
Technical parameters:
1. Input power supply: three-phase AC380V±10% 50Hz, power 1.5KW.
2. Centrifugal fan parameters: *r volume 2200m3/h, wind pressure 1000 Pa, power 1.5KW.
3. Standard flow rate: 200~1500 m3/h
4. Pipe *r flow rate: v≤15m/s adjustable;
5. Rectangular tube and round tube sizes: 3 types, the experimental *r duct is made of 304 st*nless steel.
6. Speed regulation mode: frequency conversion speed regulation.
7. No less than 4 sets of test instruments, the measuring range corresponds to the provided equipment, and the resolution is 1Pa.
8. Dimensions: 1600×500×1700mm. The shape is a st*nless steel movable bracket with double brake wheels.
9. 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 six levels of image quality are av*lable. 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.
