DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-3The utility model provides a technical solution: a combined lip seal ring test device, including a test frame and a combined test assembly arranged inside the test frame, the test frame includes a bottom plate 1, a top plate 2, a vertical plate 3 and an adjusting screw 4, the top plate 2 is arranged above the bottom plate 1 in parallel and the two are connected by the vertical plate 3, the adjusting screw 4 is threadedly inserted on the top plate 2, the combined test assembly includes a cylinder 1 5, a cylinder 2 6, a tray 7, a driving motor 8, a connecting rod 9 and an air guide 10, the cylinder The upper end of cylinder 1 5 is connected to the adjusting screw 4 and a docking cavity 11 is formed inside. Cylinder 1 6 is located directly below cylinder 1 5. An air guide cavity 12 is formed inside cylinder 1 6. A mounting opening 13 is opened in the middle of chassis 1. Tray 7 is rotatably arranged in the mounting opening 13 and the top is connected to cylinder 1 6 through three groups of connecting rods 9. Drive motor 8 is installed in the mounting opening 13 and the power output end is connected to tray 7. Air guide pipe 10 passes through chassis 1 and the inner end is located in the mounting opening 13.

[0019] Further improvement, such as Figure 2 As shown: the cylinder 5 is a hollow columnar structure and the upper end is a sealed structure.

[0020] Further improvement, such as Figure 1 As shown: the diameter of the lower end of the docking cavity 11 is larger than the diameter of the upper end.

[0021] Further improvement, such as Figure 1 As shown: the cylinder 2 6 is a truncated cone structure with an upper diameter smaller than a lower diameter, and the cylinder 1 5 and the cylinder 2 6 are made of transparent materials. This design makes it easy to splice the cylinder 1 5 and the cylinder 2 6 and to observe the internal flow conditions.

[0022] Specifically, the tray 7 is in a disc-shaped structure and has a plurality of groups of air holes 14 formed on the surface. The air holes 14 are connected to the air guide channels 12 to facilitate the flow of the colored gas.

[0023] When in use: When it is necessary to test the sealing ring of the utility model, the staff can embed the sealing ring on the surface of the cylinder body 2 6, and then screw the adjusting screw 4. The adjusting screw 4 drives the cylinder body 1 5 to move downward and allows the cylinder body 2 6 to be introduced into the docking cavity 11, so that the periphery of the sealing ring is sealed with the docking cavity 11 of the cylinder body 1 5. At this time, the staff introduces the colored gas into the installation port 13 through the air guide pipe 10, and enters the air guide cavity 12 through the air vent 14 in turn. The gas enters the docking cavity 11 and is located above the sealing ring. Observe whether the colored gas can pass through the sealing ring to reach the bottom of the sealing ring. If it can, it means that the sealing ring does not meet the standard. If not, it means that the sealing ring meets the standard. In addition, when it is necessary to test the wear resistance of the sealing ring, the driving motor 8 can be used to drive the cylinder body 2 6 to rotate, thereby driving the sealing ring to rotate and rub between the cylinder body 1 5 and the cylinder body 2 6. After testing for a period of time, observe the wear resistance of the sealing ring.
