Description

Technical Field

[0001] This utility model relates to a high-temperature detection device for pump seals, belonging to the technical field of pump seals. Background Technology

[0002] Pump seals are dynamic sealing devices used to prevent liquid leakage inside the pump. They mainly consist of a dynamic ring, a stationary ring, an elastic compensation mechanism, and auxiliary sealing rings, and achieve leakage prevention through end face sealing.

[0003] Chinese Patent Publication No. (CN 216081913 U) discloses a sealing component detection device, including a detection base, a support frame, a hydraulic rod, a sealing component mounting seat, and a sealing component. The sealing component is sleeved on the sealing component mounting seat. The top of the sealing component mounting seat is connected to the hydraulic rod, and the base of the hydraulic rod is mounted on the support frame. The airtightness detection groove has an inverted convex structure. A leakage indicator is set at the bottom of the airtightness detection groove. The sealing component mounting seat is located above the airtightness detection groove. A water tank is set on one side of the detection base. The water tank is connected to a pumping pump through a pipe. A water supply pipe is connected to the pumping pump. This utility model sets a leakage indicator at the bottom of the airtightness detection groove and places the injection pipe in the cavity formed between the sealing component mounting seat and the airtightness detection groove. When a leak occurs, water will flow into the space formed between the sealing component mounting seat and the bottom of the airtightness detection groove, thereby making the leakage indicator in the airtightness detection groove visible.

[0004] However, before using the seals in high-temperature environments, it is necessary to test their high-temperature resistance. During the test, the seals need to be immersed in high temperature for several days and then removed to observe whether they are deformed, so as to determine whether the seals meet the usage standards.

[0005] To address this issue, a high-temperature testing device for pump seals is proposed. Utility Model Content

Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] Example 1

[0028] like Figure 1-5As shown, this utility model embodiment provides a high-temperature testing device for pump seals, including a testing box 1. An isolation plate 2 is fixedly connected inside the testing box 1. A fixing mechanism 3 is provided on the top of the isolation plate 2. The fixing mechanism 3 includes a fixing block 301, a screw 302, a nut 303, and a pressing block 304. The bottom of the fixing block 301 is fixedly connected to the top of the isolation plate 2. The bottom of the screw 302 is fixedly connected to the top of the fixing block 301. The pressing block 304 is sleeved on the surface of the screw 302. The internal thread of the nut 303 is connected to the surface of the screw 302. A control box 4 is fixedly connected to the left side of the testing box 1. A heating copper pipe 5 is fixedly connected to the bottom of the isolation plate 2. The heating copper pipe 5 is electrically connected to the control box 4.

[0029] When the sealing component is subjected to high-temperature testing using the fixing mechanism 3, the sealing component is placed on the surface of the fixing block 301. After the testing is completed, the extrusion block 304 is fitted onto the surface of the screw 302. The bottom of the extrusion block 304 is pressed against the surface of the sealing component. The screw 302 is then fixed by the nut 303. The control box 4 heats the heating copper tube 5, which facilitates the staff to perform high-temperature testing on the sealing component and observe whether the sealing component is deformed.

[0030] Example 2

[0031] like Figure 1-5 As shown, in one embodiment, a fixed cover 6 is movably connected to the top of the detection box 1, and a push handle 7 is fixedly connected to the top of the fixed cover 6. A sliding groove 8 is provided on the inner side of the detection box 1, and the outer side of the fixed cover 6 is movably connected to the inside of the sliding groove 8. A cavity 9 is provided inside the detection box 1, and a pull rod 10 is movably connected to the inside of the cavity 9. A connecting rod 11 is fixedly connected to the left side of the pull rod 10. The top of the connecting rod 11 extends through the cavity 9 and into the inside of the fixed cover 6. A compression spring 12 is fixedly connected to the bottom of the pull rod 10, and the bottom of the compression spring 12 is fixedly connected to the inside of the cavity 9. A fixed groove 13 is provided at the bottom of the fixed cover 6, and the top of the connecting rod 11 is movably connected to the inside of the fixed groove 13. A limiting block 14 is fixedly connected inside the cavity 9, and the limiting block 14 is sleeved on the surface of the connecting rod 11. A limiting groove 15 is provided in the cavity 9, and the left side of the connecting rod 11 is movably connected to the inside of the limiting groove 15.

[0032] By fixing the cover 6, the pull rod 10 is pulled, and the pull rod 10 drives the connecting rod 11 to move. During the movement of the connecting rod 11, the compression spring 12 is compressed, which makes it convenient for the staff to fix the cover 6 and ensure the temperature inside the test box 1 is stable. Through the fixing groove 13, the connecting rod 11 is accurately inserted into the fixing groove 13 when it is plugged in.

[0033] When this utility model is in operation: First, pull down the pull rod 10. The pull rod 10 drives the connecting rod 11 to move downward. While the connecting rod 11 moves downward according to the movement trajectory provided by the limiting groove 15, it compresses the compression spring 12, causing the connecting rod 11 to move into the cavity 9. At this time, the fixed cover 6 can be pulled to open the detection box 1. After that, the nut 303 is removed. After removal, the extrusion block 304 is taken out. The seal to be tested is placed on the surface of the fixed block 301. The extrusion block 304 is reinstalled and fixed again by the nut 303. After that, the fixed cover 6 is closed again. After closing, the pull rod 10 is released. The rebound force of the compression spring 12 pushes the connecting rod 11 into the interior of the fixed groove 13 to fix the fixed cover 6. After sealing, when the control box 4 is started, the heating copper tube 5 is heated to immerse the seal at high temperature and detect whether the seal is deformed.

[0034] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
