Description

Technical Field

[0001] This utility model relates to the field of dry vacuum pump testing, specifically to a nanometer-level leak prevention device for dry vacuum pumps. Background Technology

[0002] Dry vacuum pumps deliver gas by compressing gas. Due to the high internal pressure, gas leakage is likely to occur in the pump body. Leakage is often detected using a cylinder leakage detector. However, when there are tiny cracks on the surface of the pump body, the leakage is not obvious to the senses and is difficult to detect. The continuous leakage will always have a negative impact on the operation and safety of the dry vacuum pump. Therefore, a nanometer-level leakage detection and prevention device for dry vacuum pumps is provided. Utility Model Content

[0003] I. Technical problems to be solved

[0004] The technical problem this invention aims to solve is that small cracks in a dry vacuum pump, leading to air leakage, are difficult to detect.

[0008] The bracket is connected to a guide frame, which has an arc-shaped slide rail. A slider that directly supports the infrared scanner is slidably connected to the slide rail of the guide frame. When the infrared scanner moves within the slide rail, its scanning lens always faces the center of the arc-shaped slide rail.

[0009] The effective coverage of external detection of the dry vacuum pump is expanded by moving the infrared scanner. The bracket is equipped with a drive assembly for driving the slider to move the infrared scanner.

[0012] Furthermore, the end of the support shaft is connected to a clamping block on one side of the guide frame two.

[0013] Furthermore, multiple casters are installed under the bracket, allowing for omnidirectional inspection of the dry vacuum pump by moving the bracket and infrared scanning device to one side of the dry vacuum pump and to the other side.

[0014] III. Beneficial Effects

[0021] The present invention will now be described in further detail with reference to the accompanying drawings.

[0022] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a nanoscale detection and leak prevention device for a dry vacuum pump, combined with an appendix. Figure 1-3 It includes: an infrared scanner 14 that performs nanoscale detection of leaking gas from a dry vacuum pump by scanning with infrared light, and a bracket 1 that supports the infrared scanner 14.

[0023] By scanning the exterior of the dry vacuum pump with infrared light, the infrared light can identify leaking gas at the nanometer level, thereby finding cracks on the pump body and realizing the process of nanometer-level leak detection.

[0024] The bracket 1 is connected to a guide frame 6, and the guide frame 6 is provided with an arc-shaped slide rail 7. The slide rail 7 of the guide frame 6 is slidably connected to a slider 8 that directly supports the infrared scanning device 14. When the infrared scanning device 14 moves within the slide rail 7, its scanning lens always faces the center of the arc-shaped slide rail 7.

[0025] By moving the infrared scanner 14, the effective coverage of the external inspection of the dry vacuum pump is expanded. Multiple casters 2 are installed under the bracket 1. By moving the bracket 1 and the infrared scanner 14 on one side of the dry vacuum pump and continuing to move them on the other side, all-round inspection of the dry vacuum pump can be achieved.

[0026] The infrared scanning device 14 for testing is installed in an arc-shaped guide frame 6, which is arranged on one side of the dry vacuum pump. The infrared scanner moves along the slide rail 7 inside the guide frame 6 to scan and identify the pump body from multiple angles on one side, covering most of the space on one side of the pump body.

[0027] By pushing or pulling the bracket 1 containing casters 2, the scanning range can be further expanded to achieve full-range coverage scanning and detection of half of the dry vacuum pump area;

[0028] After the inspection of one side of the dry vacuum pump is completed, the bracket 1 is moved to the other side of the dry vacuum pump, and the scanning behavior is repeated to complete the scanning and identification inspection of the other half of the vacuum pump area.

[0029] The bracket 1 is equipped with a drive assembly for moving the slider 8 carrying the infrared scanner 14. The drive assembly includes a screw 3 rotatably connected within the bracket 1, and a motor 4 that drives the screw 3 is mounted above the bracket 1. Figure 4 The screw 3 is threadedly connected to a screw sleeve 5, and multiple support rods 13 are connected to both sides of the screw sleeve 5. The ends of the support rods 13 are bent toward the guide frame 6 and connected to the guide frame 11 that receives the slider 8.

[0030] The guide frame and the slider 8 are connected together by a guide assembly for mutual connection and to coordinate the movement relationship between the screw sleeve 5 and the slider 8. The guide assembly includes a through slide rail 7 and a support shaft 9 connected to both sides of the slider 8. The guide frame 11 is provided with a slide groove 12. The end of the support shaft 9 passes through the slide groove 12 and is slidably connected to the guide frame 11. The end of the support shaft 9 is connected to a clamping block 10 on one side of the guide frame 11 on both sides of the guide frame 11.

[0031] Based on the size of the dry vacuum pump under test, the dimensions of the device should be designed reasonably, and the relevant power supply should be arranged accordingly.

[0032] When the motor 4 is powered on, it causes the screw 3 to rotate. The threaded sleeve 5 on the screw 3 moves up and down. The motor 4 is a forward and reverse motor. When the screw sleeve 5 carries the two guide frames 11 on both sides to move up and down, it pushes and pulls the support shaft 9 to cause the slider 8 in the guide frame 6 to carry the infrared scanner 14 to move along the slide rail 7.

[0033] Since the sliding path provided by the slide rail 7 for the slider 8 is arc-shaped, in order to match the movement behavior of the slider 8, a groove 12 is opened in the guide frame 11. The rod that supports the slider 8 adopts the support shaft 9 and is embedded in the groove 12 in a sliding connection manner, so that the slider 8 can move freely in the slide rail 7 under the influence of the screw 3 and the screw sleeve 5.

[0034] In specific implementation, this utility model can be used to detect leaks during the maintenance of dry vacuum pumps, or it can be equipped with a related walking mechanism and placed around the running dry vacuum pump for real-time monitoring of leak prevention.

[0035] During maintenance, the infrared scanner 14 is moved to one side of the dry vacuum pump under inspection. First, the motor 4 is started. With the rotation of the screw 3 and the action of the transmission and limiting mechanisms such as the screw sleeve 5, guide bracket 11, and support shaft 9, the infrared scanner 14 moves up and down on one side of the dry vacuum pump. Its scanning lens always faces the dry vacuum pump. Then, according to the relative position of the dry vacuum pump and the infrared scanner 14, the bracket 1 is moved to enable nanometer-level infrared recognition to fully cover this side of the dry vacuum pump. After this side is inspected, the bracket 1 is moved to the other side of the dry vacuum pump, and the above inspection is performed. Leakage inspection is also performed on the other side of the dry vacuum pump, thus completing the search for almost all surface leak points on the outside of the dry vacuum pump.

[0036] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
