Embodiment Construction
[0017] refer to Figure 1-3 , an inclined directional microporous end face mechanical seal structure, including a moving ring 3 and a static ring 4 of the mechanical seal. The other side of the end face of the static ring 4 is the low-pressure side, that is, the downstream side, and the end face of the moving ring 3 or the static ring 4 is provided with a microporous annular band, and the microporous annular band is arranged upstream of the end face, and the microporous annular band A continuous annular sealing dam 2 is arranged downstream of the microhole 1, and the long axis 12 of the microhole 1 has an oblique angle to the diameter 13 of the sealing end surface passing through the center of the microhole 1.
[0018] The micropores 1 are symmetrically distributed according to the center of rotation.
[0019] A plurality of micropores are evenly distributed along the radial direction on the sealing end surface.
[0020] The ratio of the major axis 12 to the minor axis 11 of...
