Description

Technical Field

[0001] This invention relates to the field of heat exchanger seal wear resistance testing technology, and more specifically, to a wear resistance testing device for heat exchanger seal production. Background Technology

[0002] A heat exchanger is a device that transfers part of the heat from a hot fluid to a cold fluid; it is also called a heat exchanger. Heat exchangers are common equipment in many industrial sectors, including chemical, petroleum, power, food, and others, and play an important role in production. The seal is one of the important components of a heat exchanger; it is installed inside the heat exchanger to support the core and provide a sealing function. Figure 1 As shown, this is a common heat exchanger seal on the market. It is large in size, occupies a lot of space, is heavy, uses a lot of material, and has a high manufacturing cost. However, the existing seal will generate a lot of friction during use, which will cause the seal to wear. In order to improve the wear of the seal, the seal will be randomly selected and polished to observe the degree of wear.

[0003] Therefore, it is necessary to provide a wear-resistant testing device for heat exchanger seal production to solve the above problems. Utility Model Content

[0004] Based on the aforementioned problems in the existing technology, the purpose of this application is to provide a wear-resistant testing device for heat exchanger seal production, which can monitor the wear of the seal.

[0005] The technical solution adopted by this application to solve its technical problem is: a wear-resistant testing device for heat exchanger seal production, including a support frame, a workbench fixedly installed at the middle end of the support frame, a control box fixedly installed at the lower end of the workbench, a grinding component provided at the middle end of the workbench, seal tooling provided on both sides of the workbench, and control buttons fixedly installed on both sides of the workbench, the control buttons being electrically connected to the control box.

[0006] Furthermore, the polishing assembly includes an electric slide rod, which is fixedly installed on the upper end of the bracket. A polishing disc is slidably connected to the lower end of the electric slide rod. A rotary motor is fixedly installed in the middle section of the polishing disc, and a polishing blade is rotatably connected to the rotating end of the rotary motor.

[0007] Furthermore, the sealing fixture includes a slide rail, which is fixedly installed on both sides of the grinding disc, and a spacing plate is slidably connected to the upper end of the slide rail.

[0008] Furthermore, a nut is threadedly connected to the upper end of the spacing plate.

[0009] Furthermore, a lower pressure plate is fixedly installed on the upper end of the spacing plates on both sides, and a telescopic cylinder is fixedly installed on the upper end of the lower pressure plate, with a gap left between the lower pressure plate and the spacing plate.

[0010] Furthermore, a position sensor is fixedly installed at the front end of the spacing plate, and the position sensor is electrically connected to the control box.

[0011] The beneficial effects of this utility model are: when the grinding distance set by the position sensor is reached, the grinding disc will stop grinding, the operating table will receive the information and control the grinding component to reset, thus ending the grinding. Finally, the staff will loosen the spacing plate and take out the seal, thereby completing the wear resistance test of the seal. Attached Figure Description

[0017] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0019] In this invention, unless otherwise stated, the orientations used, such as "up" and "down," generally refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" generally refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this invention.

[0020] like Figure 1-3 As shown, this application provides a wear-resistant testing device for heat exchanger seal production, including a bracket 1, a workbench 2 fixedly installed at the middle of the bracket 1, a control box 7 fixedly installed at the lower end of the workbench 2, a grinding component provided at the middle of the workbench 2, seal tooling provided on both sides of the workbench 2, and control buttons 3 fixedly installed on both sides of the workbench 2, the control buttons 3 being electrically connected to the control box 7.

[0021] The polishing assembly includes an electric slide bar 5, which is fixedly installed on the upper end of the bracket 1. The lower end of the electric slide bar 5 is slidably connected to a polishing disc 4. A rotary motor 13 is fixedly installed in the middle section of the polishing disc 4. A polishing pad 11 is rotatably connected to the rotating end of the rotary motor 13.

[0022] The sealing fixture includes a slide rail 12, which is fixedly installed on both sides of the grinding disc 4, and a spacing plate 9 is slidably connected to the upper end of the slide rail 12.

[0023] A tension nut 10 is threadedly connected to the upper end of the spacing plate 9.

[0024] A lower pressure plate 8 is fixedly installed on the upper end of the two side spacing plates 9, and a telescopic cylinder 6 is fixedly installed on the upper end of the lower pressure plate 8. A gap is left between the lower pressure plate 8 and the spacing plate 9.

[0025] A position sensor 14 is fixedly installed at the front end of the spacing plate 9, and the position sensor 14 is electrically connected to the control box 7.

[0026] Specifically, the staff first places the seal into the spacer plate 9, and then manually tightens the loosening nut 10 to press the seal tightly. During the process of pressing the seal, the staff can adjust the size of the spacer plate 9 by moving it on the slide rail 12, so that seals of different sizes can be easily tested for wear resistance.

[0027] After the seal is fixed, the operator starts the telescopic cylinder 6 via control button 3. The telescopic cylinder 6 drives the lower pressure plate 8 to move upward. As the lower pressure plate 8 moves upward, the operator starts the electric slide bar 5 via control button 3 to move the grinding disc 4 downward. At the same time as the electric slide bar 5 is started, the rotating motor 13 is also started. As the grinding disc 4 moves downward, the grinding disc 11 also moves downward to perform a grinding test on the seal. When the grinding distance set by the position sensor 14 is reached by the grinding disc 11, the grinding disc 11 will stop grinding. The operating table 7 will also receive the information and control the grinding components to reset, thus ending the grinding. Finally, the operator releases the spacing plate 9 and removes the seal, thus completing the wear resistance test of the seal.
