Problems solved by technology

[0004] (1) The comprehensive effect of light and salt mist (or acid mist) cannot be applied to the sample at the same time;
[0005] (2) The dry-wet cycle cannot be automatically controlled according to the dryness and wetness of the sample surface;
[0006] (3) The combination of some environmental factors is not appropriate, which leads to the complexity of the equipment

Embodiment 1

[0026] Example 1: as Figure 1 to Figure 4 As shown, a multi-factor comprehensive climate environment simulation accelerated test device includes a light source system, an intelligent spray system, a temperature and humidity adjustment system, a circulating air system and a control system.

[0027] The light source 29 system is a combination of xenon arc lamp + ultraviolet fluorescent lamp or a combination of metal halide lamp + ultraviolet fluorescent lamp, and is equipped with a corresponding controller, and a ventilation cooling and heat insulation device is installed in the light source combination. The lamps in the light source 29 can be turned on individually or simultaneously, and the power of each lamp can be adjusted within a certain range. The light source 29 is installed on the top of the test box, and the combination and power are controlled by PLC, single chip or PC program.

[0028] The intelligent spray system includes:

[0029] The surface wetness sensor 34 i...

Embodiment 2

[0035] Example 2: as Figure 5 As shown, what is different from Embodiment 1 is: the sample holder is a rotating disc holder, the lower part of the rotating disc holder is connected with a rotating shaft with a gear, the motor and the reducer drive the driving gear 37 to move, and the driving gear 37 is connected to the rotating shaft. The upper gear 38 meshes, thereby driving the rotating disc frame to rotate. After the spraying (or showering) action is completed, it is driven by the motor and the reducer, and the rotating disc frame starts to rotate, and the rotation speed and time are controlled by the control system.

Abstract

The invention discloses a multi-factor comprehensive simulation accelerated testing device for a climatic environment. The multi-factor comprehensive simulation accelerated testing device comprises a testing box in which a sample frame is arranged, a light source system, an intelligent spraying system, a temperature and humidity regulating system, a circulation air system and a control system. With the adoption of the device, an environmental effect with five environmental factors, such as illumination, corrosive medium, temperature, humidity and air speed can be simultaneously simulated or strengthened; actions, such as radiation power variation, atomizing (or spraying), heating (or cooling), air speed and the like of the light source can be controlled by using an PLC (programmable logic controller) or a singe-chip so as to simulate and strengthen a plurality of typical climate environments; drying and watering circulation on the surface of a sample in the test box can be controlled well through adopting intelligent atomizing (or spraying) control; and accelerated ratio and relevance are improved. The testing device can be used for developing two kinds of different light aging test and damp heat test so as to achieve the effect that one box has multi purposes.

Description

[0001] technical field [0002] The invention relates to a device for measuring atmospheric corrosion or environmental adaptability, which is used for multi-factor comprehensive atmospheric environment simulation acceleration test. Background technique [0003] For more than 50 years, great efforts have been made in the research and development of environmental simulation and accelerated test technology at home and abroad, and new environmental test methods have been continuously developed according to the various environments that equipment may encounter during production, storage, transportation and use. technology. These technologies continuously absorb and integrate the latest scientific and technological achievements in material engineering, mechanical manufacturing, computer, automatic control and other related disciplines, making the accelerated environmental test develop from single factor test to multi-factor combination test and then to multi-factor comprehensive t...
