Problems solved by technology

Its atomization is oscillating through the transducer, so that the water is atomized and sprayed around with the rotating nozzle. However, the way of this patented product to atomize the water cannot meet the spray power used in the salt spray test. In addition, the patented product Although the diffusion area of ​​the spray is enlarged, it will cause the discontinuity of the spray in a single area, so this patented product cannot be applied in the salt spray test at all.

Abstract

The invention relates to a spraying device for a salt spray test chamber, which comprises a tower body I, a tower body II and a tower body III, a tower head, a gas nozzle, a gas pipeline, a liquid nozzle, a liquid pipeline, a transmission device and a salt spray test chamber body, wherein a group of mutually symmetrical positioning devices are arranged at a connecting position between the outer wall of the tower body III and the inner wall of the tower body II, and the positioning devices perform positioning by adopting grooves or in a salient point manner. The invention is reasonable in design, convenient in use and uniform in salt spray deposition in the salt-spray test and enhances the accuracy and the reproducibility of the salt-spray test result.

Description

technical field [0001] The invention relates to a spray device, in particular to a spray device for a salt spray test chamber. Background technique [0002] The neutral salt spray corrosion test is a laboratory accelerated simulated corrosion test for industrial products such as metal materials, coating protection layers, parts, and electronic components. The spraying principle is: the gas generated by the compressor enters the nozzle after purification, preheating and decompression treatment, and the brine supply system supplies the brine to the suction pipe of the nozzle: when spraying, the compressed air rushes out of the nozzle, generating negative pressure above the suction pipe, Under the action of negative pressure, the salt water is quickly shot from the liquid nozzle to the top cone, and spreads to the entire space, forming a diffuse state, simulating the salt spray environment. In the neutral salt spray corrosion test, the unevenness of the salt spray deposition i...
