Abstract

The invention discloses a metal automatic grinding seal device. The metal automatic grinding seal device comprises a rotor assembly (1), a seal labyrinth (3), a seal ring (6) and a stator assembly (8) and is characterized in that a plurality of tooth tips (4) are arranged on the seal labyrinth (3), a high-temperature-resistant and wear-resistant material body is sprayed on the tooth tips (4), a honeycomb (5) is arranged on the seal ring (6), and during work, the tooth tips (4) extend into the honeycomb (5) so as to form seal fit. According to the invention, four tooth tips are arranged on the seal labyrinth, the high-temperature-resistant, wear-resistant and high-hardness material is sprayed on the tooth tips, when the rotor assembly rotates at a high speed, the diameters of the tooth tips are increased under the action of centrifugal force, and at the same time, the tooth tips grind the honeycomb, extend into the honeycomb and form close fit with the honeycomb, so that a great seal effect is played. As the seal components, such as the tooth tips and the honeycomb, are all made of high-temperature alloy, the service life of the seal device is longer, and later maintenance times and maintenance fees are also greatly reduced.
