Range hood (air volume measurement test device)
. Product name: range hood air performance test chamber
Model specifications-,
3. Standard basis: B/ and related product standards.
Applicable products include cooling fans, axial flow fans, ventilation fans, range hoods, etc.
2. Overall plan of range hood air performance test laboratory
This plan does not include the structural part of the test laboratory, which is constructed by the user according to the standard requirements

.General requirements for the laboratory
Dimensions: (width)) (length) (height) or above.
Walls: Smooth and flat, with no openings that affect air flow (air conditioning openings should not blow directly).
Ground: The ground should be kept flat.
Temperature and humidity: When the air volume is measured, the air temperature in the test room is ℃ and the humidity is - (the user provides his or her own air conditioner or dehumidifier).
Atmospheric pressure: Ordinary atmospheric environment where the altitude does not exceed one meter.
.Test system
Main components: air volume test wind tunnel, auxiliary fan and damper adjustment mechanism, measurement and control electrical cabinet (including variable frequency power supply, electrical parameter measuring instrument, pressure transmitter, tachometer, etc.), brand Computer, printer, test sample lifting platform, test sample installation flange and test air duct.
System functions: After the computer prompts you to input sample parameters and test-related data, all automatic measurement and control functions can be realized: including air volume measurement, voltage, current, power measurement, speed measurement, temperature, humidity and atmospheric pressure measurement, and test process prompts. , data tables, correlation curves, etc.
3. Power distribution requirements: The user must provide an independent power distribution switch, three-phase four-wire plus ground wire power supply:

. It can measure and plot the corresponding curves of static pressure and air volume, air volume and speed, current, power, efficiency, etc. The test sample can also be tested in two states: inhalation and discharge.
4. Test software
Adopts operating system, window interface and Chinese display.
All measured data can be collected and monitored continuously in real time in the form of numbers and tables.
3. After the test is completed, the original data can be automatically analyzed and processed statistically, displayed and printed
Test data.
Historical data query function. Data can be queried, displayed and printed based on test date, serial number, model and other parameters.
The interface and related data can be repaired according to user requirements.
