Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Fig. 1-3 are referred to, the utility model provides a kind of technical scheme：It is a kind of suitable for the highly crystalline station of high solids
Mechanical seal for pump, including connecting shaft 1, the top and bottom of the connecting shaft 1 are symmetrically arranged with mechanical sealing linkage ring seat 2, top
The top left side of mechanical sealing linkage ring seat 2 is provided with mechanical seal matrix 3, the top right of the mechanical seal matrix 3 described in portion
Side is provided with pump cover 4, and the bottom of the pump cover 4 and the top right side of mechanical seal matrix 3 are provided with J-type sealing ring 7, the J
The left bottom of type sealing ring 7 is provided with annular seal space 8, and annular seal space 8 is located on the right side of the surface of mechanical seal matrix 3, described close
The bottom of envelope chamber 8 is provided with dynamic and static ring 9, and dynamic and static ring 9 is located between mechanical seal matrix 3 and mechanical sealing linkage ring seat 2, described
Mechanical seal matrix 3 on the left of the contact position of J-type sealing ring 7 with being provided with rectangular channel 10.
Wherein, the top left side of the top mechanical sealing linkage ring seat 2 and the bottom left of bottom mechanical moving sealing ring seat 2
Earflap 5 is provided with, and two groups of earflaps 5 are respectively positioned on the left side of mechanical seal matrix 3, the surface crown of pump cover 4 is equal described in two groups
Mounting hole 6 is provided with, is easy to the installation and fixation of pump cover 4, the outer wall of the J-type sealing ring 7 is provided with pointed raised 71.
