First, the helmet UV aging box test purposes:

The helmet UV aging box is mainly used for pre-treatment of the helmet for UV aging before the helmet inspection test. The helmet is simulated for a long time of UV exposure to understand the performance of the helmet after UV irradiation.



Second, the safety helmet UV aging box operation notes:

1. The operator should first read the instruction manual of the helmet UV aging box, and be familiar with the basic performance and operation of the instrument;

2. Before the instrument is turned on, be sure to check if there is a good grounding wire to avoid danger.

3. During the whole operation experiment, the operator should wear protective clothing and protective gloves to avoid stab wounds or burns;

4. Do not place the instrument in a humid environment;

5. It is strictly forbidden to touch the high-voltage xenon lamp directly at any time by hand.

6. In order not to shorten the life of the xenon lamp, the box should be placed flat during the test so that the xenon lamp is in a vertical state during normal operation;

7. It is strictly forbidden to light the xenon lamp when the cooling fan is not working (for example, broken)! Before lighting the xenon lamp, check whether the cooling fan is working normally (the wind is blown out from the air outlet below the xenon lamp)

8. During the test, it is strictly forbidden to shake the box, otherwise the explosive lamp

Third, the function of the helmet UV aging box:

1. The ultraviolet radiation source is a 450W short-pulse high-pressure xenon lamp, which is strictly regulated in the standard;

2. It is necessary to have a cooling method to avoid explosion of the instrument due to excessive temperature during the test. It is best to use air-cooled cooling method;

3. The test temperature accuracy is 0.2%, and the test time accuracy is 1 min;

4, in order to make the instrument can be tested for a longer period of time and to ensure good test results, we use high quality power supply and trigger;

5, with the xenon lamp to extinguish the automatic stop timing function;

6, because the helmet UV aging box is illuminated with high-pressure xenon lamp, in order to make the box not corroded, so we use high-quality cold-rolled plate electric control box and high-quality stainless steel "target=_blank> stainless steel test chamber;

7, in order to make the temperature accuracy more accurate, we use high-precision stainless steel "target=_blank> stainless steel armored temperature sensor;

8. In the standard, the helmet is required to be illuminated by the xenon lamp for 400 hours. In order to improve the test efficiency, we have conducted in-depth research on the box space. In the same box space, we can make 14 helmets.

9, timing range: 0 ~ 999 hours, working power: AC220V 50Hz 800W.

Third, the helmet UV aging box preparation before the test:

1. Prepare a sample of the helmet for testing;

2. Wipe the surface of the helmet and remove the cushion and strap inside the helmet.

3. Install the xenon lamp.

Fourth, the helmet UV aging box instructions for use:

1. Install the helmet: The test box has three layers of upper, middle and lower test frames. First, the top 3 helmets should be placed. Secondly, the top 4 helmets in the middle are placed first, then the top 3 safety is placed. Cap, finally placed 4 outer helmets in the middle, a total of 14 helmets, do not squeeze the xenon lamp during installation to avoid crushing;

2. Connect the power supply of the helmet UV aging box and open the main power switch and control power switch in the control function panel. The cooling indicator light is on under normal conditions of the instrument; the temperature value displayed on the thermometer is the actual temperature value in the test chamber (the standard does not exceed 60 °C); the time is displayed as 000.00, and the first three decimal places represent hours.

3. Press the “Illumination On” button on the control function panel, the UV illumination lamp in the test chamber starts to work, and the illumination work status indicator on the instrument panel is illuminated;

4. Press “Timer Start” on the control function panel, the timer starts counting, and the timer is the accumulated time. When the set test time (400h) is reached, the timer will stop counting and the ultraviolet light will stop working. .

5. At the end of the test, take out the helmet, close the cabinet door, and turn off the power.

Five, the maintenance of the helmet UV aging box

1. Ensure the integrity of the equipment and accessories, and do a good job in daily maintenance and maintenance;

2. The equipment and equipment management personnel must be familiar with the performance of the equipment and equipment used and the operating procedures, improve the equipment technical files, and keep the technical information of the equipment and the instruction manual;

3. Keep the instrument clean and tidy;

4. If there is any abnormality in the UV aging box of the helmet, do not handle it privately. You can call our company and carry out the renovation under the guidance of our professionals.
