| description | The latex pump mechanical sealing device is composed of a double-end-face mechanical seal composed of a medium side mechanical seal and an atmosphere side mechanical seal, and is characterized in that a water seal device is arranged at an inner side port of a medium side gland shaft hole, the inner side port of the medium side gland shaft hole is sealed, and an isolation cavity between the medium side gland shaft hole and a shaft sleeve is formed; an external spiral type dynamic pressure groove is formed in the friction end face of the medium side static ring or the friction end face of the dynamic ring matched with the medium side static ring, so that the leakage amount of water seal liquid to the medium side seal is increased, the isolation cavity is filled with the water seal liquid, and the latex medium is prevented from being condensed in the space between the inner circle of the medium side static ring and the shaft sleeve; and the medium side static ring loses the axial compensation capability, so that |
