> National standard range hood air volume measurement test device. Overall plan
.This plan does not include the structural part of the laboratory building, which is left to the user according to the standard requirements
/> .Build it yourself.
..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 allow direct airflow).
.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 computers, printers, test sample lifting tables, test sample installation flanges and test air ducts.
.System functions: After the computer prompts you to input the 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.
..Power distribution requirements: Users must provide an independent power distribution switch with three-phase four-wire plus ground wire power supply:
.Maximum capacity:

.. After the test is completed, the computer can automatically calculate the measurement results
.). Maximum static pressure (static pressure value at zero air volume)
.). Maximum air volume (zero static pressure The air volume value when the air volume is pressed) /
.). The static pressure when the air volume is specified (/):
.). The main motor input power when the air volume is specified (/)
.). Regulation Full pressure efficiency % at air volume (/)
.. The corresponding curves of static pressure and air volume, air volume and rotational speed, current, power, efficiency, etc. can be measured and plotted. The test sample can also be tested in two states: inhalation and discharge.
.4. Test software
..Adopt operating system window interface and Chinese display.
..Can collect all measured data and conduct real-time monitoring in the form of numbers and tables
.Continuous monitoring.
..After the test is completed, the original data can be automatically analyzed, processed, 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.
