I. Overview:
    CRS-PV-HI hail impact test machine, with reference to IEC 61215, IEC 61646 and other relevant standard terms of design and manufacture of components used to verify the ability of anti-hail impact. Hockey used to simulate the artificial production of hail and a constant speed bump component, simulated hail impact of climate on the component.
 

Second, the main technical parameters:
1, to meet IEC61215, IEC61646 standards test requirements
2, the effective impact area: 2200 × 1300
3, the standard hail diameter: 25mm ± 5%
4, the standard hail quality: 7.53g ± 5%
5, hail set speed: 23.0m / s ± 5%
6, the speed measurement accuracy: ± 2%
7, hail mass measurement accuracy: ± 2%
8, pneumatic launching system (accuracy 0.2%)
9, the displacement is not repeatability: ≤ 5mm

Third, it works:
Compressor to the compressed air tank, pressure gauges and 25mm external diameter of the barrel, connection to install a solenoid valve, controlled by a solenoid valve opened. Barrel front mounting photoelectric speed measuring device. Adjustment gauge, the puck up to standard required impact velocity.

25mm diameter mold making hockey. The puck will be placed in the barrel is made to open the solenoid valve, compressed air pushing the puck 23m / s speed bump PV modules. The puck hit by the pilot assembly, after the appearance of visual, IV test, insulation resistance test, the quality of the components determine eligibility.

Fourth, the basic structure of the system:
1, pneumatic hockey Launch System:
    Power source for the air pressure is about 0.6 ~ 0.8MPa, need a gas storage device to store the air conditioner pressure by adjusting the air pressure changes to adjust the launch tube puck launch speed changes. Air Hockey with emission requires hardware, including high-pressure gas source, regulating equipment (regulator and air tank), trachea and solenoid valves.

2, the mechanical moving means:
PLC control mechanical transmission device to change the barrel mobile location, aiming to do with an infrared fixed point. Wherein the mechanical movement using a servo motor drive to achieve, servo motors with positioning fast and accurate advantages in a very short time positioning requirements, to ensure the reliability of experiments.

3, the sample holder:
Sample holder standard size 2400 * 1300 (L * H), can cover 2000 * 1000 standard effective surface of the component under test. Sample holder and mechanical mobile device using special aluminum processing.

4, speed test device:
Prior to launching tube rack, two photoelectric sensors middle distance 25cm, with v = s / t to get speed. Speed measuring device includes a detection sensor, high-speed response modules and software modules of three parts.
 

Fifth, the basic system configuration:

1, ice hockey mold:
Standard diameter of 25mm. Providing a mold twelve hockey mold cavity, with other laboratory equipment, such as high and low temperature test box making ice hockey.

2, hail impact test machine:
PLC control servo drive and boot hockey transmitter, the experimental data fed back to the controller, HMI as an operator terminal, with the formation of an external printer experimental data reports.

3, Instrument Accessories
Computer (including instrument operating software)
Hockey container number (save hockey use)
A refrigerator (storage puck with)
An analytical balance (precision 0.01g, maximum range 200g)
