And because it is a non-polar rubber, its electrical insulation performance is good. It is a high-elastic polymer compound, divided into natural rubber and synthetic rubber. Natural rubber is processed from the gum extracted from plants such as rubber trees and rubber grasses, and synthetic rubber is obtained by polymerization of various monomers. Rubber seals are a type of general basic component in sealing devices and play a very important role in the pair of contradictions between leakage and sealing.

[0023] The effect achieved by the entire Example 2 is that support legs 2 are fixedly connected to the bottom of the support plate 1 and near the edge at equal intervals, and the bottom of the support legs 2 is trapezoidal, which can achieve the effect of the support legs 2 supporting the bottom of the support plate 1; the limiting column 11 is located below the circular groove 7 and is adapted to it, which can achieve the effect of the limiting column 11 being embedded inside the circular groove 7; the air intake end of the air pump 15 is fixedly connected and communicated with an intake pipe 16, which can achieve the effect of the air pump 15 taking in air when it operates; a display screen 17 is embedded and installed on the outer arc wall of the support plate 1, and the display screen 17 is electrically connected to the pressure sensor 13 and the pressure sensor 18, which can achieve the effect of the pressure sensed by the pressure sensor 13 and the pressure sensor 18 being displayed on the display screen 17; the diameter of the convex disc 6 is adapted to the diameter of the fixed disc 8, which can achieve the effect of aligning the convex disc 6 with the fixed disc 8.

[0024] Working principle: The rubber seal is sleeved on the limit post 11 and placed on the support plate 1. Then, the hydraulic cylinder 5 is used to push the convex disk 6 downward. When the convex disk 6 descends, the limit post 11 can be embedded into the circular groove 7 to clamp the rubber seal. When the pressure sensor 18 senses that the pressure reaches a certain level, it stops. Then, the air pump 15 is used to inflate the rubber seal during the clamping process. When the inflation reaches a certain level, it stops. Then, the air pressure sensor 13 senses the internal air pressure of the rubber seal. When the air pressure decreases, it can be known that the airtightness leaks at this pressure level. When there is no air leakage, the pressure can be increased again for detection. This can achieve the effect of detecting the airtightness of the rubber seal under different clamping degrees, thereby improving the detection accuracy.
