Item introduction:

A. Light source：

The light source adopts 8 imported ultraviolet fluorescent lamps with a rated power of 40W as the light source. UV fluorescent tubes, distributed on both sides of the machine, 4 on each side. There are UVA-340 and UVB-313 light sources for users to choose from. The luminous spectral energy of UVA-340 lamps is mainly concentrated at the wavelength of 340nm, and the luminous spectrum of UVB-313 lamps is mainly concentrated around the wavelength of 313nm.

We use UVA-340 lamps. Since the energy output of fluorescent light will gradually decay with time, in order to reduce the influence of the test caused by the attenuation of light energy, this test box is used in all eight lamps every 1/1/2 When the life of the fluorescent lamp is 4, an old lamp is replaced by a new lamp, so that the ultraviolet light source is always composed of a new lamp and an old lamp, so as to obtain a constant output light energy. The effective life of the lamp can be about 1600 hours.

B、Electrical control：

a. The temperature of the blackboard and the condensation temperature are controlled by the controller;

b. The rest basically use imported electronic components;

Irradiance uniformity: ≤4% (at the sample surface)

Blackboard temperature monitoring: The standard Pt-100 blackboard temperature sensor is used to precisely control the surface temperature of the sample during the testing process.

Blackboard temperature setting range: BPT 40-75℃; but the actual maximum temperature limit of the temperature protection device inside the machine is 93℃±10%.

Blackboard temperature control accuracy: ±0.5℃.

c. Water tank temperature monitoring: During the cycle test, there is a test section that is a dark condensation process, which requires saturated water vapor at a higher temperature in the box. When the water vapor encounters a relatively cold sample surface, it will Condensation of dew on the surface of the sample.

The sink is located in the lower part of the box and has a built-in electric heater.

Water tank temperature control range: 40~60℃

d. The test box is equipped with a time controller, the range is 0~530H, and the power failure memory function.

e. Safety protection device:

◆Over-temperature protection in the box: When the temperature in the box exceeds 93℃±10%, the machine will automatically cut off the power supply of the lamp and heater, and enter into a balanced state for cooling.

◆Sink low water level alarm to prevent heater from burning empty.

C、Standard sample holder：

◆ Several standard sample holders of 75×150mm or 75×290mm are randomly equipped, and the maximum thickness of the sample can reach 20mm.

Non-standard size users need to specify when ordering. When the sample holder is not required, it can be loaded directly. The standard sample holder has 14 rows/side, and a blackboard thermometer is placed in one row on the back. The machine is easy to open the door.

D、Box making material：

◆ The inner tank of the box is made of SUS304# stainless steel plate

◆ The shell is made of SUS304# stainless steel plate

◆ The sample rack is made of stainless steel and aluminum alloy mesh frame, which is convenient for sample access

E、Machine overview：

◆ Size: about 1370×1350×530 mm

◆ Weight: about 150 kg

F、KUV3 Host requirements for working environment conditions：

◆ Power requirements: 220V±5%, single-phase three-wire, 50Hz, 8A, 10A slow-blow fuse is required.

◆ Environment: 5~35℃, 0~80%RH, good ventilation, clean indoor environment.

◆ Work area: about 234×353cm

Drainage: Gutters are required on the floor near the main unit.

For ease of movement, casters are installed at the bottom of the instrument, and U-rings are used to fix the position of the testing machine after the position is fixed.

Control instrument:

The equipment uses a true color touch screen PID temperature intelligent controller, which has high temperature control accuracy and good stability.

Installation site:

In order to facilitate the cooling and maintenance of the box, the place where the device is installed must meet the following conditions:

1. After installation, there should be enough maintenance space between the equipment and the adjacent wall or other equipment;

2. In order to stably exert the function and performance of the test equipment, a place with an annual temperature of 15°C to 28°C and a relative humidity of not more than 85% should be selected;

3. The ambient temperature of the installation site should not change rapidly;

Introduction to structure:

The equipment shell and inner chamber are made of high-quality SUS304 stainless steel, which is processed and formed by the most advanced processing equipment in China. The colors are coordinated and the lines are smooth. It avoids the disadvantage of surface damage caused by long-term use of aluminum plate surface spraying. The equipment studio is equipped with humidification heaters, liquid level switches, blackboard temperature sensors, etc., and eight ultraviolet radiation fluorescent lamps and ultraviolet radiation meters (optional). The bottom of the machine is installed with high-quality fixable PU movable wheels, which can easily move the machine to the designated position, and finally fix the casters.

Precautions:

1. During the operation of the equipment, a sufficient water source must be maintained;

4. When the equipment fails to troubleshoot by itself, please contact our company;

5. If you need to use it again after a long time of use, you must carefully check the water source, power supply and various components, and then start the equipment after confirming that it is correct; because ultraviolet radiation has strong hazards to personnel (especially eyes), operators should try their best to Reduce exposure to ultraviolet light (contact time should be <1min).
