IEC60879 Tower Fan Bladeless Fan Air Volume Laboratory

According to the standard requirements, the air volume testing device adopts the rectangular air volume accumulation measurement method of tower fan and bladeless fan, which can meet the air volume testing requirements of table fan, wall fan, floor fan, tower fan and bladeless fan, etc.Collect wind speed using 16 anemometers (scan horizontally before scanning up and down)

Technical Specifications:

1Airflow measurement bracket and transmission mechanism (multiple anemometers horizontally distributed, scanning from the center of the fan in the horizontal direction),40mmThe increment is scanned horizontally up and down, and all wind speeds measured at the measuring points are below24m/min.Stop scanning. Center height of anemometer1200 mmThe1500 mmAdjustable; Lateral guide rail travel2400mmLongitudinal guide rail travel2000m.

2Wind volume measurement anemometer and sensor（40 mmThe blade type anemometer has a sensitivity of not less than0.4 m/s， The most extensive program is1200 m/min）.

3The horizontal and vertical lifting mechanism of the tested machine (platform in)550mm-1300mmAdjustable within height.

4Testing distance adjustment mechanism for the tested machine (platform located at a distance from the air volume measurement bracket)600mm-1550mmAdjustable within distance

5Horizontal and concentric position adjustment mechanism of the tested machine (±)15Degree).

6Variable frequency power supply:3000VA（±2%）

7Power meter: single-phase electrical parameter meter（0.5Grade)

8Control cabinet and low-voltage electrical appliances, stepper motor drive device

9Computer, module, and interface board stepper motor driver board/RS485communication board

10Testing software

11The laboratory body adopts100mmPolyurethane cold storage panel, room6000Installed in the meter long direction1A movable wall panel with sliding rails on both sides. When the measurement is less than or equal to400mmWhen using a fan with a blade diameter, simply push the movable wall to4500mmPosition, when the measurement is greater than400mmWhen using a fan with a blade diameter, push the movable wall to6000mmposition
