The safety helmet UV aging box is mainly used for the helmet UV aging pretreatment before the helmet detection test, and the simulated helmet is exposed to long-time solar ultraviolet radiation to understand the performance of the helmet after ultraviolet irradiation.
Second, safety helmet UV aging box operation precautions:
1, the operator should first read the safety manual UV helmet aging box, familiar with the basic performance and operation of the instrument after use;
2. Before the instrument is opened, always check whether there is a good grounding wire to avoid danger;
3. The operator should wear protective clothing and protective gloves during the entire operation experiment to avoid being stabbed or scalded.
4, the instrument should not be placed in a humid environment;
5. Do not touch the high pressure xenon lamp directly at any time by hand.
6, in order not to shorten the life of the xenon lamp, the test box should be flat, so that the xenon lamp is in a vertical state during normal operation;
7. It is forbidden to turn on the xenon lamp when the cooling fan is not working (for example, broken)! Every time you turn on the xenon lamp, you should check whether the cooling fan is working properly (wind blow out from the outlet under the xenon lamp).
8, during the test, the tank is prohibited shaking, or explosive <br> <br> three lights, UV aging tank helmet should have the function:
1. Ultraviolet irradiation source is 450W short-pulse high-pressure xenon lamp, which is a strict requirement in the standard;
2, to have a way to reduce the temperature, to avoid the explosion of the instrument due to high temperatures during the test, it is best to use air-cooled cooling method;
3, the test temperature accuracy is 0.2%, the test time accuracy is 1min;
4, in order to make the instrument can be tested for a longer period of time and ensure good test results, so we use a high quality power supply and trigger;
5, with a light off automatically stop timing function;
6, because the helmet UV aging box is a high-pressure xenon lamp irradiation, in order to make the box will not be corroded, so we use is a high-quality cold-rolled plate electronic control box and high-quality stainless steel test box;
7, in order to make the temperature accuracy more accurate, we use a high-precision stainless steel armored temperature sensor;
8, the standard requires the helmet to be exposed to xenon lamp 400h, in order to improve the test efficiency, we have done an in-depth study of the space of the box, in the same box space, you can do 14 helmets;
9, timing range: 0 ~ 999 hours, power supply: AC220V50Hz800W.
Fourth, the helmet UV aging box test preparation:
1. Prepare a hard hat sample for testing;
2. Wipe the surface of the helmet clean, and remove the cushion and belt inside the helmet;
3. Install the Xenon lamp.
V. Safety helmet UV aging box Instructions for use:
1. Install the helmet: There are three layers of upper, middle and lower test frames in the test box. Firstly, the top three helmets should be placed. Next, the top four helmets should be placed in the middle, and then the top three safety boxes should be placed. Caps, finally placed in the middle of the outer four helmets, a total of 14 helmets, do not squeeze the lamp in the installation process, so as not to crush;
2. Connect the power supply of the helmet UV aging box and open the main power switch and control power switch in the control panel. In the normal condition of the instrument, the cooling indicator light is on; the temperature value displayed on the thermometer is the actual temperature value in the test box (specified in the standard cannot exceed 60°C); the time is displayed as 000.00 and the first three decimal places represent the hour.
3. Press the "Illuminate On" button on the control panel, the UV lamp in the test box starts to work, and the illumination status indicator on the instrument panel is lit;
4, press the "control time" on the control panel, the timer starts, the timer is a cumulative time, when the set test time (400h), the timer will stop timing, ultraviolet radiation lamp also stops working .
5. At the end of a test, take out the helmet, close the cabinet door, and turn off the power.
VI. Maintenance and Maintenance of Hard Hat UV Aging Box 1. Ensure the completeness of equipment, equipment and accessories, and do a good job of daily maintenance and maintenance;
2. The equipment and equipment management personnel must be familiar with the performance of the equipment and equipment, as well as the operating procedures, improve the equipment technology files, and properly keep the equipment's technical data and instructions;
3, keep the instrument clean;
4. If there is abnormality in the helmet UV aging box, do not deal with it by yourself. You can consult our company by telephone and carry out renovations under the guidance of our professional staff.
