Combined salt-spray corrosion test box

Abstract

The invention relates to a composite salt spray corrosion test box, comprising a box body (1), a spray system, a mist removal system and an electrical system. The box body (1) is provided with a box cover (2), and the box body (1) There is a working chamber (3), a sample rack (4) is arranged in the working chamber (3), the spray system includes a spray tower (5), a salt water tank (6) and a saturated barrel (7), and the spray tower (5) is provided with There are nozzles, the water inlet of the nozzle is connected to the water outlet of the peristaltic pump through a pipeline, a valve is installed at the water inlet of the nozzle, the water inlet of the peristaltic pump is connected to the water outlet of the brine tank (6) through a pipeline, and the air inlet of the nozzle is connected to the saturated bucket (6) through a pipeline. 7) The air outlet, the spray system, the defogging system, and the peristaltic pump are respectively connected to the electrical system; compared with the prior art, the present invention not only has a high degree of automation, is safe and reliable, but also has a lower flow spray function, which can realize partition control, It has the effect of saving energy and reducing consumption.

Description

[technical field] [0001] The invention relates to the technical field of environmental test equipment, in particular to a composite salt spray corrosion test chamber. [Background technique] [0002] The compound salt spray corrosion test chamber is mainly suitable for the salt spray test of parts coating, electronic components, protective layer of metal materials and industrial products. It is one of the "three defenses" test equipment in artificial climate environment. It is an important testing equipment for the adaptability and reliability of various environments in industries such as light industry, electronics, and instrumentation. The salt spray test is used to detect the anti-corrosion performance of various products. However, such mainstream products currently on the market mainly have the following deficiencies: [0003] (1) Uneven spray; [0004] (2) The spray volume cannot be precisely controlled; [0005] (3) Smaller spray volume cannot be realized; [0006] ...

AI Technical Summary

Problems solved by technology

[0003] (1) Uneven spray;

[0004] (2) The spray volume cannot be precisely controlled;

[0005] (3) Smaller spray volume cannot be realized;

[0006] (4) The spray port is easy to block;

[0007] (5) It cannot be controlled by partition. When testing small parts, the whole machine needs to be turned on, which is a waste of resources;

[0008] (6) The degree of automation is not high, centralized control is not possible, and the preservation of test history data is not ideal
