DESCRIPTION
Purpose:according toBS EN IEC 60879:2019TheGB/T13380-2015Technical specification requirements：
1 Scope of application (applicable standards)
The requirements for this air volume testing device are based on, for the convenience of walking, and because the testing methods are basically the same,Can meet the air volume testing requirements for table fans, wall fans, floor fans, and column fans.Four anemometers are used to collect wind speed (the test plane has existing ones)2On the basis of a horizontal anemometer, an increase is made in the vertical direction2An anemometer is used to represent the average wind speed on the same ring.
2 Main technical parameters and functions
2.1 Main technical parameters
Can meetTable fan, Bi fan, floor fanRequirements for air volume testing
Laboratory size:(Small fan)4500*4500*3000）Unit: mm
2.2 Main functions
Used for testing wind speed, temperature, humidity, and electrical parameters (voltage)/current/power/Power factor, speed, and time
FEATURES
accessories
1Wind volume measurement bracket and transmission mechanism (from the distance to the fan blade axis)20mmHere, to40mmThe increment moves outward, at most18Point, make sure to ensure16The minimum measuring point of the inch fan measures an average wind speed lower than25m/minheight1200 mmThe1500 mmAdjustable;
2Wind volume measurement anemometer and sensor (less than or equal to)100 mmThe blade type anemometer has a sensitivity of not less than0.15 m/sThe maximum range 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)550mm-1550mmAdjustable within distance
5Horizontal and concentric position adjustment mechanism of the tested machine（±15Degree).
6Power meter: single-phase electrical parameter meter（0.5Grade)
7Control cabinet and low-voltage electrical appliances, stepper motor drive device
8Module and Interface Board Stepper Motor Driver Board/RS485communication board
9Testing software includes testing computers.
10The laboratory body adopts50mmPolyurethane 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 to6000mmLocation.
