Description

Technical Field

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

[0002] A salt spray test chamber, also known as a salt water spray test chamber, is primarily used to test the corrosion resistance of samples. It is widely used in aerospace, automotive electronics, electrical engineering, mobile phone and digital products, plastic products, and metal materials industries to test their corrosion resistance and simulate extreme conditions under natural or working conditions to understand the performance temperature characteristics of various samples. Depending on different testing standards and requirements, salt spray test chambers can perform neutral salt spray tests, acetic acid salt spray tests, copper-accelerated acetic acid salt spray tests, and alternating salt spray tests. First, prepare a standard-compliant salt solution, check the gas and power sources, and place the samples on the test chamber's sample rack as required. Second, select the test type on the control panel and set the chamber temperature, spray interval, etc. Finally, start the equipment and begin spraying.

[0003] Salt spray testing usually takes several days to complete. The salt water tank in the salt spray test chamber has a limited storage capacity, which requires staff to replenish the salt water multiple times. Each time, the salt dissolving bucket needs to be manually lifted and poured into the salt water inlet of the salt spray test chamber's water tank, which is time-consuming and laborious. In addition, the water and salt set in the dissolving bucket need to be manually stirred, making the salt dissolving process even more complicated. Utility Model Content

[0004] In view of the above-mentioned technical problems, a salt water supply device for a salt spray test chamber is provided.

[0005] The technical means adopted in this utility model are as follows: A salt spray test chamber salt water supply device includes a salt dissolving tank, a water pump installed inside the salt dissolving tank, an outlet of the water pump connected to one end of a pumping pipe, the other end of the pumping pipe extending out of the top of the salt dissolving tank and connected to the first connector of a three-way connector, a second connector of the three-way connector connected to one end of a circulation pipe, the other end of the circulation pipe extending into the salt dissolving tank, a third connector of the three-way connector connected to one end of a water outlet pipe, the other end of the water outlet pipe connected to one end of a flexible hose via a quick connector, and the other end of the flexible hose being movably connected to the salt water inlet of the salt spray test chamber; a first valve and a second valve are respectively installed on the circulation pipe and the water outlet pipe.

[0006] Preferably, the first valve and the second valve are manual valves.

[0007] Preferably, the top of the salt dissolving tank has a water inlet.

[0008] Preferably, the water inlet is equipped with a cap that movably engages with it. The water inlet is used to pour in salt and connect to a water source. After the set amount of water and salt is poured into the salt dissolving tank, the cap can be closed.

[0009] Preferably, the salt dissolving tank is a transparent or semi-transparent salt dissolving tank, and the outer wall of the salt dissolving tank is provided with volume scale, so that the staff can observe the water volume during the water filling process and adjust the salt concentration.

[0010] Preferably, the device further includes a movable frame on which the salt dissolving tank is placed, and the bottom of the movable frame has multiple casters. The movable frame allows the salt dissolving tank to be moved freely, adjusting its position near the salt spray testing machine.

[0011] Compared with the prior art, the present invention has the following advantages: This invention utilizes a circulation pipe to automate the salt spraying process by circulating water, eliminating the need for manual stirring and simplifying the structure. Simultaneously, a water outlet pipe is used to inject salt water into the salt spray test chamber, eliminating the need for manual water pouring. This further simplifies the structure, makes it easier to modify, and is more suitable for actual factory operations.

[0012] Based on the above reasons, this utility model can be widely promoted in fields such as salt water replenishment in salt spray test chambers. Attached Figure Description
