Embodiment Construction

[0019] The embodiment of the spraying device that is used to detect casing waterproof performance:

[0020] The structure of the spraying device used in the testing process is as follows: figure 1 As shown, it includes a water storage tank 3, a paint tank 5 and a sprinkler pipe 8 with a shower nozzle 9. The water storage tank 3 has a water inlet connected to the water source and a liquid outlet connected to the spray pipe 8, and the upper end of the water storage tank 3 is also provided with a paint inlet. The water inlet pipe 1 is used to connect the water inlet and the external water source. The water inlet pipe 1 is provided with a water inlet switch valve 2 and a pressure gauge 4. The pressure gauge 4 is used to detect the water pressure entering the water storage tank 3 from the water inlet pipe 1 to control the storage tank. The water pressure in the water tank 3 reaches the set value, and the water pressure entering the water storage tank 3 by the water inlet pipe 1 ca...

Abstract

The present invention relates to a method of detecting shell waterproof performance and a spraying device of implementing the same. A colored liquid having chromatic aberration with the inner wall of a shell is used as a water spraying experiment liquid, if the waterproof grade of the shell does not accord with the requirement, the colored liquid which has the chromatic aberration with the inner wall of the shell and is easy to observe infiltrates through the shell from the corresponding gaps, so that the inner wall infiltration situation and the infiltration points can be observed conveniently after the experiment is ended to open the shell. Meanwhile, the colored liquid used in the present invention can be cleaned, so that the residual colored liquid inside and outside the shell can be cleaned conveniently after the water spraying experiment, and the situation that the corresponding color deposits on the shell to influence the beautiful outlook of the shell is avoided.

Description

technical field [0001] The invention relates to a method for detecting the waterproof performance of a shell and a spraying device for implementing the method. Background technique [0002] The HSBC cabinet and mechanism box used in power equipment are important electrical components in the field of power supply and distribution. The national standard has clearly stipulated the waterproof performance of the shell of these products. Therefore, the waterproof performance of the box-shaped shell should be tested before the equipment leaves the factory. . At present, the waterproof test of the cabinet and mechanism box casing is usually to close the casing to be tested, and then use the water spraying test equipment to spray water with a certain pressure on the outside of the casing for a certain period of time. After the time is up, the water supply is turned off and the casing is opened to observe the inside of the casing. Whether there are water traces, based on this, determ...
