XQ-61215 Hail Impact Testing Machine
1. Mainly applicable to the following products:
Photovoltaic solar products, solar water heaters, car windshields, car body exteriors, glass curtain walls, metal plates and other roof materials, and electronic equipment enclosures, etc. These products may encounter various unexpected situations during daily use, including severe weather such as hailstorms. Through the hail impact testing machine, the strength of the products is tested.
II. Operating Procedures for Hail Impact Testing Machine; 
1.Pneumatic launching device: The power source is air. A gas storage device is needed to store the air and regulate the pressure. By adjusting the pressure of the air, the speed of the ice ball launching in the launching tube can be regulated. The pneumatic launching device requires hardware components, including a high-pressure gas source, pressure regulating equipment (pressure regulating valve and cylinder), gas pipes, and solenoid valves.
2. Mechanical movement device: The microcomputer controls the mechanical transmission device to change the position of the gun barrel. The mechanical movement is achieved through the stepping motor transmission method. The stepping motor has the advantages of fast and accurate positioning, and can complete the positioning requirements within a very short time. The positioning accuracy is less than 1mm, and the cumulative error during the experiment is less than 5mm, which is far less than the requirement of no more than 10mm specified deviation from the designated position as stipulated by the IEC standard, ensuring the reliability of the experiment.
3. Sample Fixation Frame: The mechanical moving device and sample fixation frame are designed based on the size of the samples.
III. Testing Principle of the Hail Impact Testing Machine; 
The air compressor compresses the air into the storage tank. An external pressure gauge and gun tubes with standard inner diameters are connected. At the connection point, an air valve is installed, which is controlled to open by a large solenoid valve.
A photoelectric speed measuring device is installed at the front end of the barrel. Adjust the pressure gauge to ensure that the hockey puck reaches the required impact speed.
The customer specifies the diameter of the ice ball mold. The manufactured ice balls are placed in the gun barrel, and the electromagnetic valve is activated. Compressed air pushes the ice balls to collide with the photovoltaic module at a standard speed. After the module is impacted by the ice balls, it undergoes visual inspection, maximum power test, and insulation resistance test. Based on these tests, the quality of the module is determined to be qualified or not.
IV. Introduction to the Hail Impact Testing Machine：
1. Hockey puck mold: According to the standard.
We can provide ice hockey molds with multiple cavities or single cavity according to the user's requirements. Combined with other laboratory equipment, such as high and low temperature test chambers, we can manufacture ice hockey balls.
2. Electrical Control: In accordance with standards.
