Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of salt spray test equipment, in particular to a salt spray test device capable of maintaining constant temperature and humidity. Background Technique
[0002] Salt spray test is an environmental test for testing the corrosion resistance of metals and other materials. In the salt spray test, the test sample is exposed to salt spray for a certain period of time, and its performance change degree and resistance to corrosion and mildew are observed. The application scenarios of the salt spray test are mainly in the engineering field, such as the testing of automotive parts and metal parts, and in industries such as coastal ships, bridges and steel structures. The salt spray test can also simulate the corrosion conditions in the ocean and humid environment to evaluate the corrosion resistance of the test sample. In the test, the NaCl concentration in the solution is required to be relatively high, and the high concentration of NaCl will have a greater impact on the corrosion of materials.
[0003] The control of the atomization generator in the prior art generally adopts the method of timed spraying. This method is very practical in a non-constant temperature and humidity test system and can effectively save the consumption of saline-alkali solution. However, in a constant temperature and humidity environment, especially in the high-temperature mode, due to the extremely fast evaporation of the tiny droplets of salt spray, timed spraying cannot ensure the sufficiency of salt spray. And the test items are placed inside the equipment, and it is necessary to ensure the salt spray coverage range and the temperature action range surface so that the test items can maintain a stable rusting speed, resulting in a problem of resource waste. For this reason, we propose a salt spray test device capable of maintaining constant temperature and humidity. Content of the Utility Model

[0024] Among them, the heat insulation plate 6 is set as a bent columnar structure. There are several heat insulation plates 6, which are distributed in a circular shape. The heat insulation plate 6 can reduce the heat dissipation speed to the outside. The height of the heat insulation plate 6 is less than the height of the working space inside the box body 1. A water pump is arranged inside the water tank 2. The water pump is fixedly connected to the pipeline. A salt-containing liquid is placed inside the water tank 2.
[0025] Among them, the support plate 4 is arranged as an inclined columnar structure. The height of the support rod 19 is equal to the height of the fixed ring 20, and the height of the fixed ring 20 is less than the height of the mounting plate 5. Water flow can flow downward from the top of the support plate 4 into the inside of the flow collecting pipe 10.
[0026] Working principle: When the salt spray test device capable of constant temperature and humidity is in use, the heat dissipated by the heating pipe 9 installed in the inner area of the heat insulation plate 6 can be collected in the top area of the support plate 4 through the heat insulation plate 6 surrounding the outside of the support plate, reducing the heat dissipation speed. The salt spray generator 3 is used to spray the salt spray into the inside of the heat insulation plate 6 to maintain a constant temperature and humidity environment in the area where the test items are located at the top of the support plate 4, reducing the salt spray spraying range and reducing the salt spray evaporation amount at high temperature on the side, promoting the occurrence during the rusting process on the basis of resource conservation.

[0029] Working principle: When the salt spray test device capable of constant temperature and humidity is in use, the liquid can fall into the inside of the flow collecting pipe 10 through the water permeable holes. The filter 11 filters the particulate impurities in the passing liquid. After the liquid enters the inside of the circulation tank 12, when the liquid in the water tank 2 is insufficient, the water pump drives the liquid in the circulation tank 12 to be evenly sprayed onto the surface of the test items through the spray head 14, preventing the experiment from being interrupted due to insufficient liquid in the water tank 1.
