Description

Technical Field

[0001] The utility model relates to the technical field of fog testing devices, in particular to a salt spray testing device for stainless steel rods. Background Technique

[0002] Salt spray testing is an environmental test that mainly uses the artificial simulated salt spray environment conditions created by salt spray test equipment to evaluate the corrosion resistance of products or metal materials. It is divided into two categories. One is the natural environment exposure test, and the other is the artificial accelerated simulated salt spray environment test. The artificial simulated salt spray environment test uses a test equipment with a certain volume space - the salt spray test chamber. In its volume space, an artificial method is used to create a salt spray environment to evaluate the salt spray corrosion resistance quality of products.

[0003] Existing salt spray testing devices for stainless steel rods generally repeatedly test the stainless steel rods by sequentially changing the test parameters, and then judge the performance of the stainless steel rods in various environments. However, the stainless steel rods are also affected to a small extent by factors such as different batches (quality differences) and different sizes (differences in the residue amount of corrosive substances) during the test, which affects the reliability and accuracy of the test results. Therefore, we propose a salt spray testing device for stainless steel rods. Content of the Utility Model

[0019] To make the purpose, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the specific embodiments and with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other.

[0020] The following describes a salt spray test device for stainless steel rods provided by some embodiments of the present utility model in conjunction with the accompanying drawings.

[0021] Combined Figure 1-2 As shown, a salt spray test device for stainless steel rods provided by the present utility model includes: a body assembly 100 and a sealing assembly 200; wherein, the body assembly 100 includes a workbench 110, a test chamber 120 fixed on the workbench 110, a salt spray water tank 130 installed on the test chamber 120, a corrosion product tank 140 assembled on the side of the test chamber 120 and connected to the salt spray water tank 130, a water pump 150 installed on the salt spray water tank 130, an instrument panel 160 arranged on the side of the test chamber 120, and a heater 170 installed on the test chamber 120. By injecting corrosion products into the salt spray water tank 130 through the corrosion product tank 140, the composition of the salt spray test can be adjusted. Then, the water pump 150 sprays the test water source in the salt spray water tank 130 onto the stainless steel rods in the test chamber 120. At the same time, the heater 170 can regulate the environmental temperature in the test chamber 120, and the data of the test environment is then displayed through the instrument panel 160 for reference and adjustment.

[0022] Among them, the sealing assembly 200 is arranged on the workbench 110. The sealing assembly 200 includes a bottom plate 210 arranged on the workbench 110, a collection bin 220 opened in the workbench 110 and located below the bottom plate 210, a sewage cover 230 connected to the bottom of the collection bin 220, jacks 240 opened on both sides of the test chamber 120, side plates 250 installed on both sides of the test chamber 120, a sand filling layer 260 filled in the side plates 250 and covering the jacks 240, a pressing plate 270 pressed on the sand filling layer 260 and located between the side plates 250, a drain pipe 280 connected to the pressing plate 270, and a sealing water tank 290 installed on the test chamber 120 and connected to the drain pipe 280. Through the sealing assembly 200, multiple stainless steel rods of different sizes can be inserted through the test chambers 120 with different test environments for testing, and the sand filling layer 260 is used to seal around the stainless steel rods outside the jacks 240 to ensure the sealing performance. By continuously adding water to the lower part of the pressing plate 270 through the sealing water tank 290, the sealing performance of the sand filling layer 260 can be further improved, ensuring the stable and reliable progress of the test.

[0023] Specifically, the bottom plate 210 is of a grid mesh plate structure, and a screen 211 is laid on the bottom plate 210. The grid mesh plate structure is convenient for the discharge of sewage during the test, and the screen 211 can prevent the sand filling layer 260 from leaking downward, which is relatively practical.

[0024] Further, an arc-shaped groove for limiting the stainless steel rod is provided on the bottom plate 210, which can limit the stainless steel rod and ensure its stability.

[0025] On the other hand, the test chamber 120 is provided with three groups for a single stainless steel rod to pass through, and the salt spray water tanks 130 on the test chamber 120 are connected in series. The three groups can also be multiple groups, which can be set as required. Connecting in series can ensure that the water sources in the test chamber 120 are the same, and further ensure the reliability of the test.

[0026] It should be noted that a baffle 121 is clamped on the outermost side plate 250 of the test chamber 120. It only exists on the outermost side plate 250. The side plates 250 between the test chambers 120 are against the test chambers 120 on both sides, and the range of the sand filling layer 260 can be limited in turn.

[0027] Further, a pressure pad 122 is installed inside the test chamber 120 above the jack 240, which can press on the stainless steel rod in its own weight state to prevent the sand filling layer 260 from entering the test chamber 120 excessively, which is relatively reasonable.

[0028] The working principle and usage process of the present utility model: First, insert multiple stainless steel rods with different sizes through multiple test chambers 120 with different test environments for testing. Then, put the sand filling layer 260 between the side plates 250, and then press the pressing plate 270 on it. The sealed water tank 290 continuously introduces water sources into the sand filling layer 260 through the drain pipe 280 to seal the periphery of the stainless steel rod, and then the test can be carried out.

[0029] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
