    Multiple - Nozzle Air Flow Test Equipment Standard Range Hood / Ventilator Air Duct For Household

    Multiple - Nozzle Air Flow Test Equipment Standard Range Hood / Ventilator Air Duct For Household


    ● Overview:

    This device is applied to testing the air flow performance of range hood and ventilator for


    household and similar purposes, and is in accordance with testing requirements of GB/T 1236


    Industrial Fans-Performance Testing Using Standardized Airways, and requirements of ISO


    5801, JIS B8330, JIS C9603 and other standards.


    ● Test principle:

    Based on the Bernoulli's principle of Fluid Mechanics, use the pressure difference before and


    after flowing through the nozzle to calculate the air velocity and then the air flow can be acquired


    through multiplying the air velocity by the cross-sectional area of nozzle. During the test, use


    auxiliary fan and regulating damper to change air flow and then measure static pressure under


    different air flow values. Finally, air performance curve of range hood or fan can be acquired


    through computer data processing.


    ● Performance and features

    ① This device adopts multiple-nozzle air chamber type structure. As it can select corresponding


    nozzles according to the tested flow, so this device has wide flow measurement range.

    ② It can be used for exhaust and gas absorption test.

    ③ Equipped with auxiliary fan, it can measure full range performance curve when airflow is zero


    and static pressure is zero.

    ④ Equipped with imported high accuracy pressure sensor, the testing result is accurate and


    reliable.

    ⑤ Automatic test, calculation and data output can be achieved through computer and peripheral


    equipment and the testing result can be displayed in graphics and printed. With human-machine


    interaction, it is simple in operation, and high in accuracy and takes less time and energy.

    ⑥ Testing items: Automatic or manual P-Q features (relation between flow and static), Q-W


    features (relation between flow and power), Q-η feature (relation between flow and efficiency) and


    current and power of tested object by synchronous test.

    ⑦ This device applies to performance test of ventilator, air-conditioner fan, cooling fan, range


    hood and others.


    ● Technical parameters

    ① Air flow measurement range 0.1-50m3/min;

    ② Static pressure measurement range 0-1500Pa

    ③ Measurement error of air flow ±1%(under the maximum air flow of each nozzle).
