Technical Field

[0002] A mechanical seal is a device that prevents fluid leakage by maintaining contact and relative sliding between at least one pair of end faces perpendicular to the axis of rotation under the action of fluid pressure, the elastic force (or magnetic force) of the compensation mechanism, and the cooperation of an auxiliary seal. A mechanical seal with a metal bellows auxiliary seal for the compensation ring is called a bellows mechanical seal. Mechanical seals are precision, structurally complex basic mechanical components and are key parts of various pumps, reaction vessels, turbine compressors, submersible motors, and other equipment.

This utility model, by setting a replacement component, allows the fixing ring to be removed from the inside of the first or second connecting cylinder. The appropriate fixing ring can be replaced according to the thickness of the mechanical seal body, thereby enabling the device to adapt to the connection work of mechanical seal bodies of different thicknesses, expanding the applicability of the device. By setting a fixing component, the upper fixing plate cooperates with the lower fixing plate to clamp and fix the mechanical seal body. The entire process only requires rotating a fixing screw to fix the mechanical seal body, eliminating the need for a large number of bolts, shortening the time required to fix the mechanical seal body, and improving the working efficiency of the device.

Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0020] Implementation Please see Figure 1 -4. A testing device for machining mechanical seal components, comprising: Base plate 1; A movable plate 2 and a fixed plate 14 are set on the base plate 1. A fixed shell 3 is set on the upper side of both the movable plate 2 and the fixed plate 14. A clamping component 4 is set inside the fixed shell 3 for clamping materials. An inflation component 8 is provided inside the fixed shell 3 located on the upper side of the fixed plate 14, and a detection component is provided on the upper side of the base plate 1. The inflation component 8 is connected to the detection component. A sealing assembly is provided on the outer wall of the fixed shell 3 located on the upper side of the movable plate 2; The clamping assembly 4 includes a rotating disk 41 rotatably connected inside the fixed housing 3 and a fixed cylinder 44 rotatably connected inside the fixed housing 3. The fixed cylinder 44 is fixedly connected to the rotating disk 41, and a spiral pattern 42 is provided on one side of the rotating disk 41. A clamping block 43 is slidably connected to the inner wall of the fixed shell 3, and the rear side of the clamping block 43 engages with the spiral pattern 42 on the outer wall of the rotating disk 41. The sealing assembly is disposed on the outer wall of the other side of the fixed shell 3. The sealing assembly includes a sealing disc 22 disposed on the outer wall of the fixed shell 3 and a sealing angle 21 fixedly disposed on the sealing disc 22. A sealing sheet 20 is fixedly disposed on the other side of the sealing disc 22. One end of the fixed cylinder 44 is fixedly connected to the first gear 5, and the outer wall of the fixed shell 3 is rotatably connected to the second gear 6. The first gear 5 and the second gear 6 mesh with each other, and a rotating rod 7 is provided at the center of the second gear 6 to rotate the second gear 6. The detection assembly includes a high-pressure gas tank 12 fixedly mounted on the base plate 1 and a connecting pipe 10 located at the output end of the high-pressure gas tank 12. An adapter 9 is provided at the end of the connecting pipe 10. The connecting pipe 10 is connected to the inflation pipe 84 through the adapter 9. A pressure gauge 11 is provided on the outer wall of the connecting pipe 10, and a pressure holding valve 13 is provided on the outer wall of the connecting pipe 10. The pressure gauge 11 is located in front of the pressure holding valve 13.

[0021] The technical solution provided in this embodiment is as follows: When testing the seal, the test piece is first placed at the center of the clamping assembly 4 of the fixed side housing 3. Then, the second gear 6 is rotated, which drives the first gear 5 to rotate, thereby driving the rotating disk 41 to rotate. The spiral pattern 42 drives multiple clamping blocks 43 to clamp one side of the test piece. Then, the screw 18 is rotated, and the moving plate 2 is moved by the threaded block 17 threadedly connected to the screw 18. When the sealing sheet 20 contacts the seal, the clamping assembly 4 on the moving side clamps the test piece. After the initial clamping is completed, the screw 18 is rotated again to make the sealing sheet 20 and the rubber sheet 81 tightly connected to both sides of the test piece, ensuring the airtightness of the connection. Then the test can be carried out. During the test, open the pressure holding valve 13 and inject the high-pressure gas inside the high-pressure gas tank 12 into the test piece. Observe the change of the pressure gauge 11. After reaching the preset value, close the pressure holding valve 13 and observe the pressure gauge 11 at all times. If the pressure drops, there is a leakage. If the pressure remains unchanged, the sealing is good.

An inflation tube 84 is fixedly disposed on the rear wall of the fixing plate 82. The air inflator 84 passes through the rotating disk 41.

[0023] Specifically, by having the air tube 84 pass through the rotating disk 41, the air tube 84 will not be interfered with when the rotating disk 41 is rotated, and the rubber sheet 81 can ensure an airtight seal during testing, avoiding errors during testing.

[0024] Furthermore, the lower wall of the movable plate 2 is provided with a slider 16, and the interior of the base plate 1 is provided with a groove 15, with the slider 16 slidably connected to the inner wall of the groove 15.

[0025] Specifically, the arrangement of the slide groove 15 and the slider 16 ensures the movement accuracy of the moving plate 2 and prevents poor sealing of the test piece due to excessive error when the moving plate 2 moves.
