Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of technical solution referring to FIG. 1-2: a kind of 2BV water ring pump Double-plate machine seal structure, including
Outer layer jacket 1 and nest 3, the nest 3 is set to the both ends of 1 side of outer layer jacket, and the end of the outer layer jacket 1 is embedding
Entering the inside that the nest 3 is set, the side of the nest 3 is equipped with the mounting hole 7 arranged around the nest 3,
For the mounting hole 7 through being arranged in the nest 3, the inside of the mounting hole 7, which is equipped with, reinforces screw rod 8, the reinforcement
