Description
Technical Field
The utility model relates to a withstand voltage test system, a pneumatic withstand voltage test device specifically says so.
Background
Many sealed components are tested for sealing after they are finished or assembled to prevent leakage during use before they are submitted to the user. Because water is with low costs, the resource is many, and in case the spare part seepage, can have water to flow out fast, so detect spare part leakproofness and adopt hydrostatic test more. The hydraulic test tool is designed into an integral structure, one end of the hydraulic test tool is designed into a flange structure matched with a reserved interface of a pressure test part, the hydraulic test tool is connected with the pressure test part by a bolt and sealed by a special gasket, the other end of the hydraulic test tool is welded with a section of pipeline and connected with a pressure test rubber pipe, once leakage occurs in the test, the connecting bolt needs to be unscrewed, the hydraulic test tool is disassembled, and the hydraulic test part is reassembled to continue to complete the test after being repaired; and after the pressure test is finished, one pressure test part is switched to the pressure test of the next part. Therefore, the existing hydraulic test not only needs to design a special tool, but also is complicated to install before the test, long in leakage and part replacement, and low in working efficiency.
