Description

Technical Field

[0001] The utility model relates to the technical field of mechanical engineering, in particular to a multifunctional shaft sealing device test bench. Background Art

[0002] A shaft seal test rig is a device used to test and evaluate the performance of shaft seals. It simulates actual operating conditions, such as shaft rotation and dynamic axial and radial displacement, to test the durability, sealing performance, and reliability of the seals. This test rig is commonly used in marine applications, machinery, and other areas requiring high-precision sealing to ensure that the seals effectively prevent leakage and other failures in actual use.

[0003] When testing shaft seals, test rigs simulate real-world operating conditions to evaluate seal performance. This involves applying dynamic axial and radial displacements, similar to those encountered in shipboard or other machinery. In these test environments, if the seal design is flawed—for example, if the sealing material lacks elasticity or the seal-shaft fit is loose—then the seal may not maintain a seal when the shaft moves. This can cause the sealing surfaces to pull apart or squeeze, leading to water or other fluid leakage from the seal contact points. As the test progresses, fluid begins to seep from the seal gaps and gradually accumulates on the test rig. If the leakage is large, it can quickly spread and affect other parts of the test rig. This not only prevents the current test from continuing, but also necessitates pausing the experiment to clean up the leaked fluid and inspect the equipment for any damage. Frequent leaks and cleanup efforts are time-consuming and inconvenient.

[0004] In view of this, we propose a multifunctional shaft sealing device test bench. Utility Model Content

When the drive motor 25 is started, it drives the transmission shaft 26 to rotate, and the transmission shaft 26 drives the dummy shaft 28 to rotate. The support seat 27 is used to stably support the transmission shaft 26.

[0028] The outer wall of the fixed plate 34 is fixedly connected to the support seat 27, which plays a role in fixing and supporting the fixed plate 34. The inner wall of the fixed plate 34 is rotatably connected to the outer wall of the transmission shaft 26. When the transmission shaft 26 rotates, the fixed plate 34 will not rotate. The outer wall of the transmission shaft 26 is fixed to the guide slide block 37. When the transmission shaft 26 rotates, the guide slide block 37 is driven to rotate. The outer wall of the sliding block 39 is slidably connected to the inner wall of the guide slide block 37. The guide slide block 37 drives the sliding block 39 to rotate.
