Description

Technical Field

[0001] The utility model relates to the field of test equipment, in particular to a salt spray test device. Background Art

[0002] The existing salt spray chambers on the market all use manual flow control valves to control the compressed air flow, thereby controlling the amount of salt spray deposition in the chamber. The salt spray deposition is manually measured using physical measuring instruments, which has low accuracy and can only reflect the data during the measurement period. It is impossible to record the actual deposition data throughout the test.

[0003] This means that before each test, it is necessary to confirm again whether the salt spray deposition meets the requirements, which usually takes several hours, is very time-consuming, and has low accuracy. If the test conditions change, it is necessary to manually adjust the flow of compressed air and repeatedly test and verify. Only after confirming that the requirements are met can the test be carried out. Such debugging can take a few hours at the shortest and one or two days at the slowest. If there is a new emergency test of salt spray deposition, it cannot be met. Therefore, we proposed a salt spray test device to solve the above problems. Utility Model Content

[0009] Preferably, the flow controller is connected in series between the air compressor and the brine barrel to control the amount of compressed air injected by the air compressor.

[0011] Preferably, a pressure balancing hole is provided on the salt spray box.

[0012] Preferably, it further comprises a lifting assembly, wherein a plurality of lifting assemblies are provided, and each lifting assembly is respectively provided at the bottom of the monitor and the salt spray nozzle;

[0018] Moreover, when the regulating controller compares the actual salt mist deposition amount with the set amount, if the salt mist deposition amount is greater than the set amount, the compressed air injection is reduced by one order of magnitude, otherwise the compressed air injection is increased by one order of magnitude, thereby realizing automatic adjustment and achieving accurate and stable control of the salt mist deposition amount, while recording the deposition amount data in real time. Therefore, the whole process can solve the previous tedious work of inaccurate manual control and repeated manual measurement and verification, and realize real-time and accurate control of the salt mist deposition amount through automatic control, which greatly saves time and ensures the accuracy of the test, while providing the deposition amount record data throughout the test.

When the regulating controller 3 compares the actual salt mist deposition amount with the set amount, if the salt mist deposition amount is greater than the set amount, the compressed air injection is reduced by one order of magnitude, otherwise the compressed air injection is increased by one order of magnitude, thereby realizing automatic adjustment and achieving accurate and stable control of the salt mist deposition amount, while recording the deposition amount data in real time. Therefore, the whole process can solve the previous tedious work of inaccurate manual control and repeated manual measurement and verification, and realize real-time and accurate control of the salt mist deposition amount through automatic control, which greatly saves time and ensures the accuracy of the test, while providing the deposition amount record data throughout the test.
