Description

Technical Field

[0001] The utility model relates to the technical field of material corrosion resistance testing devices, and more specifically, to a material corrosion resistance testing device with a salt spray spraying system. Background Technique

[0002] In material science research and industrial production, evaluating the corrosion resistance of materials is a crucial step. Especially in industries such as automotive, aviation, shipbuilding, and electronics, materials need to be exposed to harsh environmental conditions for a long time, such as salt spray corrosion in marine atmospheres. This poses a severe challenge to the durability and safety of materials. Currently, in order to study the corrosion resistance of materials, corrosion resistance testing operations are usually carried out on corresponding corrosion resistance testing devices. There are many types of corrosion resistance testing devices on the market, and most of them are equipped with salt spray spraying systems to achieve simulation operations by spraying salt spray. However, such salt spray spraying systems can only spray salt spray and cannot perform cleaning operations with clean water on the inside of pipelines and nozzles, etc. After the salt spray spraying ends, since there is a lot of salt in the salt spray, when the moisture in the subsequent pipelines and nozzles dries, salt will solidify on the inner walls of the pipelines and nozzles, causing blockages and affecting the normal spraying operation next time. In view of this, we have proposed a material corrosion resistance testing device with a salt spray spraying system.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-4, the present utility model provides a technical solution: a material corrosion resistance testing device with a salt spray spraying system, including a corrosion-resistant box 1. On the front side of the corrosion-resistant box 1, there are two symmetrically arranged sealing doors 11 hinged by hinges. Closing the sealing doors 11 can achieve the effect of sealing and protection;

[0026] Specifically, a salt spray spraying component 2 is arranged on the corrosion-resistant box 1. The salt spray spraying component 2 includes a brine cylinder 20, a clear water cylinder 21, and an atomizing pump 24 arranged outside the corrosion-resistant box 1. The water inlet end of the atomizing pump 24 is fixedly installed with a suction pipe 241. The end of the suction pipe 241 is fixedly installed with an electromagnetic three-way valve 25. The remaining two pipe bodies of the electromagnetic three-way valve 25 are respectively connected to the brine cylinder 20 and the clear water cylinder 21 through water inlet pipes 251. The water outlet end of the atomizing pump 24 is fixedly installed with a delivery pipe 26. The end of the delivery pipe 26 is fixedly installed with an output pipe 27. The bottom of the output pipe 27 is fixedly installed with a plurality of atomizing nozzles 271 arranged at equal intervals. The atomizing nozzles 271 are located inside the corrosion-resistant box 1, ensuring that during use, the atomizing pump 24 can be used to transport the brine in the brine cylinder 20 for corrosion resistance testing operations. After the spraying is completed, the atomizing pump 24 can be used to transport clear water into the pipeline and the atomizing nozzles 271 for cleaning operations, which is convenient for use.

[0027] In this embodiment, a plurality of support legs 10 arranged in a matrix are fixedly installed on the bottom surface of the corrosion-resistant box 1. The height of the support legs 10 is 60 cm to 120 cm, enabling the support legs 10 to achieve the effect of stable support.

[0028] Specifically, the capacity of the clear water cylinder 21 is 15 L to 25 L. An electric heating rod 211 is fixedly installed inside the clear water cylinder 21. After heating the water body with the electric heating rod 211, hot water is then transported into the pipeline, promoting the dissolution of salt in the hot water and facilitating its smoother discharge.

[0029] Furthermore, threaded pipes 22 are fixedly installed on the top surfaces of both the brine cylinder 20 and the clear water cylinder 21. Sealing caps 23 are threadedly connected to the threaded pipes 22, facilitating the opening of the sealing caps 23 to achieve the operation of adding brine or clear water using the threaded pipes 22.

[0030] In addition, a first rigid pipe 28 is fixedly installed on one side plate of the corrosion-resistant box 1. The water outlet end of the first rigid pipe 28 is communicated with the outside. The water inlet end of the first rigid pipe 28 is fixedly installed with a flexible pipe 282. The water inlet end of the flexible pipe 282 is fixedly installed with a second rigid pipe 283. The second rigid pipe 283 is sleeved on the output pipe 27 and is slidably connected to the output pipe 27. An electric push rod 29 is fixedly installed on the side wall of the corrosion-resistant box 1. The second rigid pipe 283 is arranged on the telescopic shaft of the electric push rod 29, facilitating the collection and discharge operations of the clear water sprayed from the atomizing nozzles 271 by sleeving the second rigid pipe 283 on the output pipe 27, which helps to reduce the interference of clear water.

[0031] It should be noted that a solenoid valve 281 is fixedly installed on the first rigid tube 28. The solenoid valve 281 is located outside the corrosion-resistant tank 1, which is convenient for controlling the connection operation of the first rigid tube 28 by using the solenoid valve 281.

[0032] It should be noted that a fixed bump 291 is fixedly installed on the second rigid tube 283. The fixed bump 291 is fixedly installed on the telescopic shaft of the electric push rod 29; a sealing plate 272 is fixedly installed on the end tube body of the output tube 27. The end plate body of the second rigid tube 283 abuts against the side of the sealing plate 272 for sealing operation to reduce the leakage of clear water.

[0033] When the material corrosion-resistant test device with a salt spray system of the present utility model is in use, control the electromagnetic three-way valve 25 to connect the brine cylinder 20 with the atomizing pump 24. Connect the atomizing pump 24 to an external power supply and make it work. When the atomizing pump 24 works, the brine in the brine cylinder 20 is atomized and sprayed out from the atomizing nozzle 271, so as to perform the corrosion-resistant test operation on the material placed in the corrosion-resistant tank 1;

[0034] After the brine spraying is completed, start the electric push rod 29 and make it work. When the electric push rod 29 works, the telescopic shaft on it extends to drive the second rigid tube 283 to sleeve on the output tube 27 and the atomizing nozzle 271. At the same time, the end of the second rigid tube 283 abuts against the sealing plate 272. Then control the electromagnetic three-way valve 25 to connect the clear water cylinder 21 with the atomizing pump 24. Start the atomizing pump 24 and make it work. When the atomizing pump 24 works, the clear water is conveyed and sprayed out from the atomizing nozzle 271. Then open the solenoid valve 281, and the sprayed clear water can be discharged outwards along the second rigid tube 283, the first rigid tube 28 and the hose 282.
