Hail impact testing machine

Model:HTPV-09

Namehailimpacttesting machine

Applicable standardIEC61215, IEC61646, UL1703 standard requirements

Purpose:Verify the ability of the component to resist hail impact. Artificially made ice hockey is used to simulate hail and impact the component at a constant speed, simulating the impact of hail climate on the component.

Technical specifications:

1. Launch device

a、 power source：compressed air

b、 Air pressure: 6-8 bar

c、 ice hockey：Manual single shot loading

d、 Barrel length：About 940mm

e、The gun barrel can be replaced

2. Mobile positioning device

aThe定位精度≤1mm

c、Guiding directionformula：High quality imported guide rails

d、Drive Type：Imported servo motor+synchronous wheel

e、Positioning control method：The upper computer controls automatic positioning

3. Speed measurement system and principle

a、By measuring ice hockeyBy passing through an infrared speed sensor and simultaneously capturing the time when the infrared is blockedt， Calculate ice hockey based on V=S/tflylineofspeed

b、 The speedometer adopts high-precision infrared speed sensor

c、 Infrared speed sensor accuracy ± 5%

d、 Speed grasping range 0～40 m/s

e、 Ice hockey speed: diameter 25 Mm ice hockey speed 23.0m/s ± 5%

35 mm diameter ice ball speed 27.2m/s ± 5%

Diameter 45 Mm ice hockey speed 30.7m/s±5％

4. Ice hockey preparation method and mold

a、Inside the ice hockey moldnoteAfter filling with water, place it in the freezer compartment of the refrigerator. After the water cools and freezes, separate the molds and remove the ice balls, placing them on the ice ballsstorage boxInternal refrigeration for backup.

b、 The mold is made of a special material that is not easily swollen or deformed

c、 Inner cavity diameter 25mm ＜ 1%; 35mm＜1％； 45mm＜1％

d、 The first mock examination 6 ice hockey balls;match2 setsice hockeymold

e、 The processing technology for the inner cavity of the mold adopts high-precision CNC machine tools for machining

f、 Ice hockey diameter 25mm ＜ 5%; 35mm＜5％； 45mm＜5％
