Industrial Fan Airflow Laboratory

The air volume measurement test device is an air volume testing system developed and manufactured based on the GB/T1236 standard and advanced Japanese technology.

The basic testing principle is to simulate the actual working state of the test sample in the testing wind tunnel (using an auxiliary fan to make the outlet pressure of the test sample consistent with the requirements), then measure the pressure difference on both sides of the nozzle in the wind tunnel, calculate the corresponding wind speed using a standard formula, and finally multiply it by the nozzle area and relevant flow coefficient to obtain the air volume.

The device adopts computer automatic measurement and control mode, automatically installing test samples and replacing nozzles. It can measure the corresponding curves of static pressure and air volume, air volume and speed, current, power, efficiency, etc. It is also possible to inhale and expel the test sample

Test in two different states. It has the characteristics of convenience, speed, stability, reliability, and good reproducibility. Satisfy the testing and use of related products in scientific research and production processes.

II Overall Plan

This plan does not include the laboratory building structure, which will be constructed by the user according to standard requirements.

1.General laboratory requirements

Wall: Smooth and flat, without any openings that affect airflow (air conditioning openings should not be blown directly).

Ground: The ground should be kept flat.

Temperature and humidity: When measuring air volume, the air temperature in the laboratory is 20 ℃± 5 ℃ and the humidity is 30% -80% (the user should bring their own air conditioner or dehumidifier).

Atmospheric pressure: an ordinary atmospheric environment with an altitude not exceeding 1000 meters.
