Climate simulation device for salt spray testing machine

Abstract

The invention discloses a climate simulation device for a salt spray testing machine. The invention belongs to the technical field of experimental equipment, and the device comprises a control module,a rain-snow module and a fan module; the rain and snow module comprises a water tank, a first water pump, a water pipe, rain nozzles, an air compressor, an airflow pipe and snow nozzles; one end of the water pipe is connected to the water tank; the first water pump is arranged on the water pipe; the other end of the water pipe is connected with a plurality of branch pipes; the multiple rain nozzles are evenly distributed and connected to the branch pipes through branch pipes, the snow nozzles and the rain nozzles are arranged in a one-to-one correspondence mode and connected to the branch pipes in parallel, first water valves used for opening and closing the rain nozzles and second water valves used for opening and closing the snow nozzles are arranged on the branch pipes, one end of theairflow pipe is connected to the air compressor, and the other end is connected to the snow nozzles. According to the salt spray testing machine, rainfall weather, snowfall weather and rain and snow weather can be simulated, the salt spray testing machine has climate simulation conditions at the same time, the experiment requirements are better met, and the water use requirements of rainfall simulation and snowfall simulation can be met by adopting one waterway system.

Description

technical field [0001] The invention relates to the technical field of experimental equipment, in particular to a climate simulation device for a salt spray test machine. Background technique [0002] With the rapid development of science and technology, economy and trade, human beings are exploiting and utilizing resources in the natural environment more and more widely, and the environment encountered in the use of various materials and equipment products is becoming more and more complex and increasingly complex. Cruelty, from tropical to frigid, from plains to plateaus, from oceans to space, etc., also makes people pay more attention to the performance, reliability and safety of materials and products in various environments. In order to achieve the above goals, effective experiments must be carried out in various environments. If field experiments are carried out in various environments, there are disadvantages such as long cycle, high cost, and difficult implementatio...

Problems solved by technology

If field experiments are carried out in various environments, there are disadvantages such as long cycle, high cost, and difficult realization. However, various environmental simulators can help people get rid of the laws of nature, and the environmental factors in the simulator can be set according to the purpose of the experiment.

The salt spray test machine is a simulator used to test the salt spray corrosion ability of materials and their protective layers. However, the existing salt spray test machines generally do not take into account the influence of climate factors on the salt spray test, and the experimental conditions are not very good. meet the experimental requirements, not enough to fully verify the performance of the material or its coating under various climatic conditions
