Embodiment Construction
[0023] The specific implementation manner of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings.
[0024] Such as Figure 1 to Figure 3 As shown, the bushing structure used for filter tightness testing, the bushing structure is set inside the air cover for filter tightness testing, and the lower end of the bushing 5 is provided with an opening for fitting on the filter , The bushing is provided with a through hole 503 for internal and external ventilation.
[0025] The structure of the gas mask 3 includes a gas mask cylinder 301 and an air nozzle 304 arranged on the gas mask cylinder. The gas mask cylinder 301 is a cylindrical structure with an open lower end. An annular sealing ring, the top of the cylinder body of the gas mask is provided with a connecting head 302 for connecting with the down-pressing cylinder 4 .
[0026] Place the vertical filter to be tested on the detection platform...

The invention discloses a bushing structure for filter sealing performance detection. The bushing structure is arranged inside an air hood for filter sealing performance detection; the lower end of the bushing is provided with an opening sleeving the filter; and a through hole performing ventilation internally and externally is arranged in the bushing. According to the bushing structure for filtersealing performance detection, the structure is reasonably designed; the bushing is arranged between the air hood and the filter, the air cavity range between the air hood and the filter is ensured,bubbles coming out of a detection water box are thus ensured to be stable, and capturing and analyzing are facilitated; and the bushing is convenient to fetch, and the operation is facilitated.
Description
technical field [0001] The invention relates to the technical field of filter detection, in particular to a bushing structure used for filter tightness detection. Background technique [0002] Sealing problems are prone to occur between the end of the filter and the cover plate inside the end of the filter, so the produced filter needs to be tested for tightness. At present, there is no special detection device for the filter airtightness test, and most of them detect the air pressure through artificial end seals, or through the cover. The space between the filter and the cover is relatively large, which affects the analysis of the detection structure. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a bushing structure for filter tightness detection, so as to achieve stable detection results and facilitate analysis. [0004] In order to solve the problems of the techn...
