Fan performance testing bench

Fan performance testing bench

1、 System Introduction
This system is developed and manufactured based on the energy efficiency evaluation standards for fans, combined with the actual production conditions of many fan manufacturers.
The entire system is divided into four parts, namely:
1. Wind chamber system
2. Stress testing system
3. Fan power measurement system
4. Test the control system
Instructions:
1). In the above four parts, the wind chamber system can be provided with design drawings or key components by our side, and the wind chamber construction can be completed by the wind turbine manufacturer, or it can be fully constructed by our side.
2). The pressure measurement system may vary depending on the overall plan.
2、 Technical parameters
1. Test standard: GB/T 1236-2006 GB/T 10562-2006
2. Technical parameters (air volume measurement)
(1) Measurement items: Fan dynamic pressure, fan static pressure, fan total pressure.
(2) Airflow range: 200~16000m3/h (can be determined according to user needs)
(3) Wind pressure range: 0~2500pa (can be determined according to user needs)
(4) Working condition requirements: Temperature: 0-40 ℃;
(5) Wind speed: 2-30m/s
(6) Repeatability accuracy: 5%, 2%, 0.5%
3. Technical parameters (power measurement)
(1) Voltage: 450V
(2) Current: Direct measurement, 0-100A, high current can be measured using a transformer.
(3) Operating temperature -20-60 ℃
(4) Accuracy: 1%
3、 Product Features
(1) Easy to operate, once the fan is installed in place, simply touch the switch and the system can start measuring, automatically recording the pressure at each value
Automatically draw curves for air flow rate and real-time fan power.
(2) Multiple comparison function: Compare multiple fan curve graphs, making the advantages and disadvantages of the fans clear at a glance, providing clear guidance for fan improvement.

(3) Using an industrial computer as the control terminal makes the system safer and more stable.
