Description

Technical Field

[0001] The utility model relates to the technical field of airtightness detection, in particular to a device for detecting the airtightness of an air compressor. Background Art

[0002] An air compressor is a device used to compress gas. The structure of an air compressor is similar to that of a water pump. Most air compressors are reciprocating piston type, with rotating blades or rotating screws. Centrifugal compressors are very widely used. After the air compressor is produced, it needs to be tested for tightness before it is put into use on the market. For example, patent application number CN202311087711.2 is an air compressor leakage detection device, comprising a mobile base, a blower fixedly connected to the top of the mobile base, an air inlet pipe connected to one side of the blower surface, and a filter cartridge inserted into the inside of the air inlet pipe. The present invention inflates the air storage tank through an air injection head, detects the air pressure inside the air storage tank through an air pressure connector, and seals the connecting box through a baffle, which can automatically stop inflation, ensuring that the pressure environment inside the air storage tank is relatively stable during the detection process. The effect of the threaded connection drives the pneumatic component to slide in the slot, which can be adjusted according to the set pressure value of different air storage tanks, and is convenient for different detection work requirements. The air is filtered by the air inlet pipe and the filter cartridge when absorbing air, which can effectively prevent excessive impurities in the air from entering, affecting the pressure in the tank, and preventing blockage of the pipeline. The air inlets of air compressors of different specifications are different, and the air compressor inlet and the connector of the above-mentioned detection device are difficult to replace, and cannot be replaced according to the specifications of the air compressor inlet, and it is not easy to detect the airtightness of air compressors of different specifications.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] (1) When it is necessary to test the tightness of the air compressor, connect the connector to the air inlet of the air compressor. At this time, the air pump is used to work and fill the air into the air compressor. When the air is inflated to a certain pressure, the air pump is stopped to inflate. The inflation pressure can be detected by the first pressure detector and the second pressure detector. After observing the pressure value, if the pressure value does not change, the tightness of the air compressor can be guaranteed. Otherwise, the tightness is not good. By inflating the air into the air compressor, if the air compressor is not tight, air leakage will occur, which is convenient for staff to check and repair.

[0013] (2) When it is necessary to replace different connectors to inspect air compressors of different specifications, the staff rotates the connecting column so that the threaded head at the top of the connecting column rotates inside the threaded hole, and the threaded head rotates inside the threaded hole so that the threaded head disengages from the threaded hole, so that the connecting column can be disengaged from the sliding plate. At this time, the positioning ring will not be constrained inside the positioning groove, and the first connecting plate and the second connecting plate can be disconnected. Conversely, the first connecting plate and the second connecting plate can be fixed together, and the sliding plate can be moved backward by rotating the sliding plate.

The sealing ring 12 is arranged inside the sealing groove 11. Arranging the sealing ring 12 inside the sealing groove 11 can make the relationship between the first connecting plate 8 and the second connecting plate 9 more sealed.

[0024] like Figure 2 、 3As shown in , 4, and 5, the positioning assembly 7 includes an external thread 701, a sliding plate 702, a positioning groove 703, and a positioning ring 704. The external thread 701 is arranged on the side of the connecting pipe 5, the sliding plate 702 is installed in the middle of the connecting pipe 5, the positioning groove 703 is opened on the surface of the first connecting plate 8, the positioning ring 704 is fixedly installed on the surface of the second connecting plate 9, the positioning ring 704 is arranged inside the positioning groove 703, and an internal thread 706 is provided on the inner wall of the sliding plate 702, and the internal thread 706 is engaged with the external thread 701.

[0025] The working principle of this air compressor tightness detection device:

[0026] When in use, when it is necessary to test the air tightness of the air compressor, connect the connector 10 to the air inlet of the air compressor. At this time, the air pump 1 is used to work to fill the gas into the air compressor. When the air is inflated to a certain pressure, the air pump 1 is stopped to inflate. The inflation pressure can be detected by the first pressure detector 2 and the second pressure detector 6. After observing the pressure value, if the pressure value does not change, the air tightness of the air compressor can be guaranteed. Otherwise, the air tightness is not good. By inflating the air into the air compressor, if the air compressor is not airtight, air leakage will occur, which is convenient for the staff to check and maintain. When it is necessary to replace different connectors 10 to check air compressors of different specifications, the staff can rotate the connecting column 705 to connect When the screw thread head 707 at the top of the connecting post 705 rotates inside the screw hole 710, the screw thread head 707 rotates inside the screw hole 710, and the screw thread head 707 disengages from the screw hole 710, so that the connecting post 705 can be disengaged from the sliding plate 702.

Conversely, the first connecting plate 8 and the second connecting plate 9 can be fixed together, and the sliding plate 702 can be rotated to move the sliding plate 702 backward. When the connecting post 705 is installed, the connecting post 705 will be driven to move backward, so that the first connecting plate 8 and the second connecting plate 9 are more tightly connected. This device can conveniently disassemble and replace the connector 10 and test air compressors of different specifications.
