Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a salt spray test chamber. Background Technology

[0002] Salt spray testing is a primary environmental test that uses salt spray testing equipment to create simulated salt spray conditions to test the corrosion resistance of products or metallic materials. Stainless steel is widely used in heavy industry, light industry, and consumer goods, such as sinks, indoor pipes, water heaters, bathtubs, boilers, automotive parts, medical equipment, building materials, chemicals, food industry, textile industry, cheese industry, and ship parts.

[0003] The stainless steel salt dew test is a method to examine the corrosion resistance of stainless steel. Stainless steel sheets contain many different elements, including iron, chromium, carbon, and various alloys, with iron being the main component and chromium being a major alloying element. Generally, a chromium content of at least 11% is required to qualify as stainless steel. Insufficient chromium content prevents the formation of a dense chromium oxide protective film on the surface of the stainless steel, resulting in a loss of its rust-resistant properties. With sufficient chromium content, it will not rust at room temperature in atmospheric conditions.

[0004] However, existing salt spray testing equipment cannot adjust the spray volume, thus failing to meet the testing requirements for products of different specifications. Utility Model Content

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a salt spray test chamber that can adjust the spray volume according to the needs of different products, thus meeting the testing requirements of products of different specifications.

[0006] A salt spray test chamber according to an embodiment of the present invention includes: a chamber body, comprising a first chamber body and a second chamber body, the first chamber body having a first cover on its top, a carrying rack inside the first chamber body, the first chamber body and the first cover being closed to form a sealed spray chamber; a spray mechanism disposed in the chamber body, comprising a heating chamber, a spray tower disposed on the top of the heating chamber, and a salt spray nozzle disposed on the spray tower, the first chamber body having a water tank, the heating chamber being disposed in the water tank, the second chamber body having a salt water tank and a saturation tank, the salt spray nozzle being connected to the salt water tank via a water pipe, the salt spray nozzle being connected to the saturation tank via an air pipe, and the spray tower having an adjustable tower cover on its top, the adjustable tower cover being adjustable to adjust the spray volume.

[0007] A salt spray test chamber according to an embodiment of the present invention has at least the following beneficial effects:

[0008] 1. This utility model, by setting up a first chamber and a second chamber, with a first chamber cover on the top of the first chamber, can form a closed spray chamber. The product to be tested is placed on a carrier, thereby enabling salt spray testing of the product to be tested.

[0009] 2. This utility model, by setting up a spray mechanism, connects the brine tank and saturation tank to the salt mist nozzles via water pipes and air pipes, respectively, enabling the salt mist nozzles to spray a large amount of salt mist. Pure water is added to the water tank, and a heating box heats the water in the tank, controlling the temperature inside the spray chamber. The salt mist sprayed from the nozzles enters the spray tower and exits from the top. Simultaneously, the adjustable tower cover at the top of the spray tower can adjust the spray volume, thus allowing for adjustments to different spray volumes according to the needs of different products, meeting the inspection requirements of products with different specifications.

[0010] According to some embodiments of the present invention, the adjustable tower cover includes a fixing ring, a disperser, and a connecting rod for connecting the fixing ring and the disperser. The fixing ring is sleeved on the outside of the spray tower and is fixed to the spray tower by bolts. The disperser is located above the spray tower.

The fixing ring is fitted around the outer circle of the spray tower, and the disperser is located above the spray tower, so that the disperser is suspended above the spray tower. The fixing ring can move along the length of the spray tower and is then fixed to the spray tower with bolts. The distance between the disperser and the spray tower can be adjusted, and thus the spray volume can be adjusted, making it convenient for operators to make adjustments.

[0012] According to some embodiments of this utility model, the disperser is conical.

[0013] The advantage is that by making the disperser conical, the salt mist sprayed from the top of the spray tower is diffused in all directions through the conical disperser, thereby enabling the sprayed salt mist to be evenly distributed in every corner of the spray chamber, improving the accuracy of the detection.

[0014] According to some embodiments of the present invention, a fog collecting funnel is provided inside the first box, and a fog meter is provided outside the first box. The fog collecting funnel and the fog meter are connected by a flexible hose.

[0019] The advantage is that by setting up a drain hole, a drain pipe, and a water plug, opening the water plug allows the water in the water-sealed groove to be discharged into the water tank along the drain pipe, thus facilitating the emptying of the water in the water-sealed groove.

[0020] According to some embodiments of the present invention, the brine tank is located above the saturation tank, the top of the brine tank is open, and the top of the second tank is provided with a water filling cover, which corresponds to the top of the brine tank.

[0021] The advantage is that by setting up a water inlet cap, brine can be added to the brine tank by opening the cap, making full use of the space in the second tank and thus saving on the manufacturing cost of the equipment.

[0022] According to some embodiments of the present invention, a water supply pipe is connected to one side of the saturation tank, the water supply pipe is located outside the second tank, and one end of the water supply pipe extends to the top of the second tank.

[0023] The advantage is that by setting up a water inlet pipe, water can be injected from the water inlet pipe while the equipment is running, thus facilitating the replenishment of water in the saturated tank.

[0024] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description
