Embodiment Construction
[0041] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0042] The structure of the mechanical seal structure embodiment of the present invention is as follows Figure 1 to Figure 8 shown. It includes a hexagonal column 1 in the ring groove, a reinforcing rib 2 on the sealing end surface, and a sealing surface 3 . The inner diameter of the entire mechanical seal structure is Φ1, the outer diameter is Φ2, the axial thickness of the mechanical seal structure is L, and the bottom thickness of the circumferential groove of the mechanical seal structure is δ. The hexagonal column 1 in the ring groove is located in the middle of the groove, the width of the two parallel and opposite sides 4 and 5 is c, the length of the two parallel and opposite sides 4 and 5 is d, and the distance between the two vertices is e. 18 are evenly distributed along the circumference of the mechanical seal structure, and th...

The invention provides a mechanical sealing structure with a honeycomb-shaped groove in the cylindrical surface. The honeycomb-shaped groove is formed in the outer circular end face, namely the cylindrical surface A, of the mechanical sealing structure in the radial direction and circumferential direction of a cylinder. The honeycomb-shaped groove is composed of hexagonal prisms (1), reinforcing ribs (2) in sealed faces and the sealed faces (3), wherein the hexagonal prisms (1) are located right in the middle of the honeycomb-shaped groove, namely an annular groove, and the reinforcing ribs (2) are each in a semi-hexagonal prism shape and integrated with the sealed faces (3). By applying the mechanical sealing structure to existing non-contact mechanical sealing, the advantages of reshaping of the sealed end faces can be brought into play to a higher extent, the sealing and lubricating effects and stability are remarkably improved, and the service life of the mechanical sealing structure is greatly prolonged.
Description
technical field [0001] The invention provides a mechanical seal structure with honeycomb-shaped grooves on the cylindrical surface, specifically, a certain number of honeycomb-shaped grooves are provided in the radial and axial directions on the outer cylindrical surfaces of the moving ring and the static ring. The invention belongs to the technical field of rotary shaft sealing in fluid sealing. Background technique [0002] The mechanical seal is an axial end face sealing device that relies on the elastic element to preload the dynamic and static ring end face seal pairs and compress the medium pressure and the elastic element pressure to achieve sealing, so it is also called end face seal. Mechanical seals are widely used in equipment such as centrifugal pumps, centrifuges, reactors and compressors. With the continuous advancement of science and technology, mechanical seals are required to adapt to extreme working conditions such as high pressure and high speed in practi...
