Model utility content
The technical problems to be solved in the utility model is, provides a kind of and avoid spring failure, makes rotating ring end face stress equalization, mechanical sealing device used for pump easy for installation.
The technical solution of the utility model is, a kind of mechanical sealing device used for pump with following structure is provided, and comprises the mechanical sealing base, rotating seat, rotating ring, stationary ring and a plurality of stop pin that are all socketed in rotating shaft; Described stationary ring and rotating shaft close-fitting also circumferentially link with mechanical sealing base, between the outer wall of described stationary ring and the inwall of mechanical sealing base, are provided with the first seal ring, are provided with the second seal ring between described rotating ring and rotating seat, and described rotating ring and rotating seat circumferentially link; It also comprises many springs, described rotating ring is located in the hole of rotating seat, and one end end face is force-fitted on the end face of stationary ring by spring, described many springs are located in the corresponding blind hole in inside of rotating seat, the interior edge face of every spring one end and rotating ring offsets, and the blind hole inner bottom surface of the other end and rotating seat offsets; Described rotating ring and rotating seat are provided with the spring collar of axial limiting rotating ring, and the inner wall sleeve of described spring collar is connected on the outer wall conical surface place of rotating ring, and the outer wall of described spring collar is embedded in the annular groove of inwall of rotating seat.
Described spring collar is shape ringwise, and is provided with first breach.
Described rotating ring and rotating seat circumferentially interlock refer to, the inner side of the interior edge face of described rotating ring is provided with a plurality of the second breach that embed one by one for one end of stop pins, and the other end of stop pin is fixed in the hole of interior edge face of rotating seat one by one.
Adopt after said structure, the utility model compared with prior art, has the following advantages:
1, due in spring sealed cavity on rotating seat and rotating ring, avoid directly contacting with material, avoid spring failure.
2, because spring is many, and be embedded in respectively in the cavity on rotating seat and rotating ring, can make rotating ring end face stress equalization.
3, when using assembling, spring, rotating ring, rotating seat are pre-installed, and with spring collar by spring and rotating ring axial limiting in rotating seat, make so easy for installation.
