DX8683 Building Curtain Wall Anti - Wind Debris Testing Equipment

Product Overview
This device is a performance testing equipment designed and developed in accordance with the new standard "Classification and Testing Method for Wind and Fragile Impact Resistance of Building Curtain Walls and Doors and Windows" modified by foreign standards such as ASTM E1886-2005 and ASTM E1996-2008. The detection object is limited to the building curtain wall, exterior doors and windows, and storm protection device specimens themselves, and does not involve the connection parts between the building curtain wall, exterior doors and windows, storm protection device, and other structures. The device is designed with simplicity, easy assembly, adjustable and controllable pressure, adjustable launch height, and convenient experimental operation.

[Technical parameters]
1. Environmental temperature: -10 ℃~50 ℃;
2. Air cannon working pressure: 0.4-0.8MPa;
3. Environmental temperature: -10 ℃~50 ℃;
4. Steel ball requirements: mass 2g ± 0.1g, diameter 8mm;
5. Steel ball launch speed: 39.7m/s
6. Rated voltage of solenoid valve: AC 220V;
7. The detection device consists of a projectile, a launch device, a speed measuring device, and a passive pressure box
8. The wooden block is made of pine or cork, with a dry density of 500kg/m³ ± 25kg/m³, a cross-sectional height of 38mm ± 1mm, and a width of 89mm ± 1mm. One end of the wooden block specimen is called the impact end, and the other end is called the end;
[Product Features]
This device uses two photoelectric sensors of the same model, and records the time when the emission passes through the two sensors through an electronic timer. The response frequency of the electronic timer shall not be less than 10KHz, and the response time shall not exceed 0.15ms. The velocity of the projectile is calculated by dividing the distance between two photoelectric sensors by the time recorded by the electronic timer.
