LR-8791 IEC61215 PV Module Hail Impact Resistance Testing Machine/Tester ASTM E822
Product Overview:
This test system is designed in strict accordance with IEC61215, UL1703, the latest standard. Used to verify the resistance of component glass to hail impact. Artificial hockey balls are used to simulate hail and strike the components at a constant speed to simulate the effect of hail climate on the components.
Scope of application:
Umbrella, tent, PHOTOVOLTAIC module, glass, greenhouse, solar panel, film, solar panel, building insulation material, resin tile, car clothing, composite laminate, photovoltaic module, aviation composite material, carbon fiber laminate, bubble rice sandwich structure radome, aircraft and other impact test.
Relevant standards:
1, ASTM E822-1992(2015) Practice for Determination of Hail Impact Resistance of Solar collector covers by the Impelling Hockey Ball Impact Method.
2. GB/T 33235-2016 Test method for hail impact resistance of photothermal power glass mirror.

System composition:
1. Pneumatic launching device: the power source is air, and an air storage device is needed to store the air regulating
pressure, and the speed of the puck in the launching tube can be adjusted by adjusting the change of air pressure.
Pneumatic aunchers require hardware coordination, including high-pressure air sources, regulating equipment (regulating valves and cylinders), air pipes and solenoid valves.
2. Mechanical moving device: microcomputer control mechanical transmission device to change the moving position of the gun barrel, infrared fixed point to do the aiming. Including mechanical mobile use, stepping motor drive for stepping motor has the advantages of rapid, accurate positioning, positioning can be completed in a very short time requirements, positioning accuracy is less than 1 mm, the cumulative error is less than 5 mm, far less than the IEC standards required by the specified location deviation is not more than 10 mm, to ensure the reliability of the experiment.
3. Sample holder: Design mechanical moving device and sample holder according to sample size. The standard size is
2000*1350(L*H), which can cover the effective surface of the tested component within 2000*1350.
4. Speed test device: before the transmitter tube, the distance between the two photoelectric sensors is 50cm, and the speed is obtained by V = S/T, which will be displayed in real time and changed when the sample speed is measured next time. The speed testing device includes three parts: detection sensor, high-speed response module and software module. The system uses stable photoelectric sensor and programmable controller to achieve, and provides HMI man-machine interface as the operating terminal,with external printer to form experimental data reports.

rWorking principle:
The air compressor compresses the air to the air storage tank, and is connected with the pressure gauge and the gun barrel with 25mm inner diameter. An air valve is installed at the connection, which is controlled and opened by a large solenoid valve.
The front end of the barrel is fitted with a photoelectric velocimeter. Adjust the pressure gauge to make the puck reach the
standard impact speed. A hockey ball mold with an inner diameter of 25mm was made. The hockey ball was placed in the barrel of the gun, the solenoid valve was opened, and the compressed air pushed the hockey ball to hit the photovoltaic module at a speed of 23m/s. After the component is impacted by the puck, the quality of the component is judged to be qualified after the appearance inspection, maximum power test and insulation resistance test.
Component is introduced
1. Puck mold: the standard diameter is 25mm.
According to the user's demand, we can provide a multi-hole or one-hole hockey mold, cooperate with other laboratory equipment,such as high and low temperature experimental box to make hockey.
2. Electrical control: microcomputer control step driver and transmitter, experimental data feedback back to the controller,man-machine interface as the operation terminal, with the external printer to form experimental data reports.
