Frist,Definition and structure of dumbbell seal ring
Dumbbell type sealing ring is a round seal consisting of two flanges, two sealing feet and a thin-walled structure connecting two sealing feet. Its outer surface and inner surface are spherical surfaces with specific curvature.
Second, dumbbell sealing ring material
Dumbbell type seals are generally made of rubber or polyurethane materials, which have good sealing properties, wear resistance and oil resistance, and can withstand high and low temperatures.
Third, dumbbell sealing ring manufacturing process
The manufacturing process of dumbbell seal ring is mainly divided into compression molding, injection molding and extrusion molding. Compression molding is the most commonly used manufacturing process because it can produce high-performance seals.
Fourth, dumbbell seal ring application field
Dumbbell seal ring is widely used in machinery, automobile, metallurgy, chemical industry, aviation, aerospace and other fields. It can be used to seal liquid, gas, dust and other media, and can withstand high pressure and high temperature.
Fifth, Dumbbell seal ring standard and its selection principle
Dumbbell seal ring standards mainly include ISO, DIN, ANSI and other international standards and national standards. Factors such as medium type, temperature, pressure, radial clearance and structural characteristics should be considered when selecting dumbbell type sealing ring. At the same time, the flatness and surface roughness of the sealing surface should be considered to avoid leakage due to poor contact.
Dumbbell seal ring is an important seal in modern industry, it has a wide range of applications and corresponding standards, the selection of appropriate dumbbell seal ring to ensure the normal operation of machinery and equipment and extend the service life is of great significance.
