Shenzhen electric fan performance testing device

The measuring device shall comply with the technical specifications of BS EN IEC 60879:2019, using the rectangular air volume accumulation measurement method for tower fans and bladeless fans, and shall meet the air volume testing requirements for tower fans and bladeless fans Collect wind speed using 16 anemometers (scan horizontally before scanning up and down)

1. Place the table fan on the lifting platform and adjust the distance between the axis of the table fan blades and the rear wall to be at least1200mm,Place the table fan on the lifting platform and adjust the height of the fan blade axis of the table fan to1500mmAdjust the fan to keep the blades perpendicular to the ground. (Calibration of accompanying level)

2. Use the remote control to adjust the front and rear movement guide rails to make the distance between the fan blades and the center of the anemometer ringdFor the diameter of the fan blades3Twice. Place the spirit level at the center of the left and right guide rails, adjust the left and right guide rails and anemometer to make them on the same plane, and then adjust the vertical guide rail to be perpendicular to the left and right guide rails. adjust4An anemometer is aligned with the axis of the fan blades, so that8An anemometer is on the same plane and parallel to the fan blades.

3. Set the manual forward, backward, left, and right movement speeds separately (it is recommended to set the speed to5mm/s）Switch to manual mode, first adjust the left anemometer to move left and right according to the monitoring screen so that the laser and anemometer center are aligned, click zero, and wait for the anemometer to automatically run140mmOperate on the right, front, and back using the same steps. If the anemometer and laser cannot be aligned during the operation process, an internal device needs to be used6Adjust the position of the anemometer with an angle wrench (as shown in the following figure)
