Description

Technical Field

[0001] This utility model relates to the field of mechanical seal technology, specifically an ordered testing device for testing mechanical seals. Background Technology

[0002] Mechanical seals are shaft sealing devices mainly used in rotating fluid machinery such as centrifugal pumps, centrifuges, and reactors. Their core structure consists of a stationary ring and a rotating ring. Through the contact and relative rotation of the stationary and rotating rings, they prevent fluid leakage. Mechanical seals undergo a sealing test before leaving the factory. One common testing method involves filling the mechanical seal with a certain amount of gas and then immersing the entire seal in water. If no bubbles emerge, the seal is considered sealed; if bubbles emerge, it is considered unsatisfactory. Finally, the mechanical seal is dried to prevent corrosion. While this testing process is reasonable, the gas filling, immersion, and drying processes are scattered and all require manual operation, resulting in low efficiency and significant physical exertion for workers. Therefore, improving the efficiency of water immersion testing for mechanical seal sealing while minimizing physical exertion for workers has become an urgent problem for relevant technical personnel. Utility Model Content

[0021] Furthermore, a rubber pad 15 is fixedly installed on the upper part of the base 14.

[0022] Furthermore, a lower cylinder 10 is fixedly installed on the upper inner side of the lifting frame 23. The lower cylinder 10 is located directly above the base 14. The output end of the lower cylinder 10 is vertically downward. A connecting plate 9 is fixedly installed on the output end of the lower cylinder 10. A motor 18 is fixedly installed at the lower center of the connecting plate 9. The output shaft of the motor 18 is vertically downward. A turntable 19 is horizontally installed below the motor 18. The center of the turntable 19 is fixedly connected to the output shaft of the motor 18. An inner drying cylinder 12 and an outer drying cylinder 17 are vertically installed at the lower part of the turntable 19.

[0023] Furthermore, a lower groove 21 is provided at the lower part of the turntable 19, and an upper groove 20 is provided at the upper part of the turntable 19. The upper groove 20 is connected to the lower groove 21. A bolt 22 is provided on the inner side of the upper groove 20. The central axes of the inner drying cylinder 12 and the outer drying cylinder 17 are respectively connected to the corresponding bolts 22. The central axes of the inner drying cylinder 12 and the outer drying cylinder 17 are slidably connected to the lower groove 21.

[0024] Furthermore, there are two sets of lower troughs 21 and two sets of upper troughs 20. The two sets of lower troughs 21 are symmetrical to each other, and the inner drying cylinder 12 and the outer drying cylinder 17 each correspond to one set of lower troughs 21.

[0025] The working principle of an ordered detection device for detecting mechanical seals of the present utility model is as follows: Place the mechanical seal 13 on the base 14, making the inner wall of the mechanical seal 13 fit with the clamping seat 16. At this time, the lower surface of the mechanical seal 13 fits with the rubber pad 15. Loosen the bolt 22 and move the inner drying cylinder 12 and the outer drying cylinder 17 respectively until, in the top view direction, the inner drying cylinder 12 is internally tangent to the inner wall of the mechanical seal 13 and the outer drying cylinder 17 is externally tangent to the outer wall of the mechanical seal 13. Then, tighten the bolt 22 again. Connect the connector 24 to the gas charging position of the mechanical seal 13. Open the regulating valve, and after filling a certain amount of gas into the mechanical seal 13 through the air pump 3 and the hose 7, close the regulating valve. Start the upper cylinder 11 to lower the lifting frame 23 until the mechanical seal 13 is completely immersed in the clear water in the transparent cylinder 8. Observe through the transparent cylinder 8 whether there are bubbles emerging from the mechanical seal 13. If no bubbles emerge, the sealing performance is qualified; if bubbles emerge, it is unqualified. After the observation, reset the lifting frame 23, remove the connector 24, start the lower cylinder 10 to lower the turntable 19 until the inner drying cylinder 12 and the outer drying cylinder 17 respectively fit with the inner wall and the outer wall of the mechanical seal 13. Start the motor 18, and the output shaft of the motor 18 drives the turntable 19, the inner drying cylinder 12, and the outer drying cylinder 17 to rotate as a whole. The inner drying cylinder 12 and the outer drying cylinder 17 respectively fit with the inner wall and the outer wall of the mechanical seal 13 and rotate relatively at the same time until the inner wall and the outer wall of the mechanical seal 13 are wiped dry. Thus, a complete detection process can be completed. It should be noted that the inner drying cylinder 12 and the outer drying cylinder 17 do not involve specific complex structural designs for realizing the drying function, and the surface can be a simple water-absorbing material. In addition, this device does not involve the work of wiping the upper and lower surfaces of the mechanical seal 13, but it does not affect the saving of the staff's physical strength in the wiping link.

[0026] Above are only the specific implementation manners of the present utility model, but the protection scope of the present utility model is not limited thereto. Any change or replacement that can be thought of without creative labor should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope defined by the claims.
