Abstract
The utility model discloses a pump mechanical sealing device. The pump mechanical sealing device comprises a mechanical sealing base (1), a dynamic ring base (2), a dynamic ring (3), a static ring (4) and a plurality of rotating preventing pins, wherein the mechanical sealing base (1), the dynamic ring base (2), the dynamic ring (3), the static ring (4) and the rotating preventing pins are arranged on a rotating shaft in a sleeved mode. The circumferential limiting of the static ring (4) and the mechanical sealing base (1) is that the inner side of the inner end face of the static ring (4) is provided with a plurality of notches (4.1), wherein one end of each rotating preventing pin can be embedded into the corresponding notch (4.1), and the other end of each rotating preventing pin is fixed into the corresponding hole of the mechanical sealing base (1). According to the pump mechanical sealing device, the mechanical strength of the static ring can be guaranteed, and the service life of the static ring can be prolonged.
Description
Technical field
The utility model relates to mechanical seal device, is specifically a kind of mechanical sealing device used for pump.
Background technique
Pump is generally all provided with mechanical seal device, this mechanical seal device comprises mechanical sealing base, rotating seat, rotating ring, stationary ring and Duo Gen spring and the stop pin being all socketed in rotating shaft, described stationary ring and rotating shaft close-fitting are also circumferentially spacing with mechanical sealing base, between the outer wall of described stationary ring and the inwall of mechanical sealing base, be provided with the first seal ring, between described rotating ring and rotating seat, be provided with the second seal ring, described rotating ring and rotating seat circumferentially link.Rotating ring in this structure rotates along with the rotation of rotating shaft, and stationary ring and rotating ring form sealing flour milling and realize pump inside and extraneous sealing.
Described stationary ring and mechanical sealing base be spacing spacingly realize by stop pin circumferentially, the end face at the interior edge face of stationary ring is provided with a plurality of grooves that run through inside and outside wall, one end of each stop pin is embedded in the groove that stationary ring is corresponding one by one, the other end is embedded in the hole of mechanical sealing base, there is following shortcoming in the mechanical sealing device used for pump of above prior art: because the groove on stationary ring runs through inside and outside wall, reduce like this mechanical strength of stationary ring, affected the working life of stationary ring.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of and guarantee the mechanical strength of stationary ring, the mechanical sealing device used for pump in the working life of increase stationary ring.
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 are also circumferentially spacing 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; Described stationary ring and mechanical sealing base be spacing referring to circumferentially, and the inner side of the interior edge face of described stationary ring is provided with a plurality of breach that embed one by one for one end of stop pin, and the other end of stop pin is fixed in the hole of mechanical sealing base one by one.
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, have the following advantages: because the inner side of the interior edge face of described stationary ring is provided with a plurality of breach that embed one by one for one end of stop pins, the groove that soon originally ran through inside and outside wall is revised as breach, do not run through inside and outside wall, can guarantee like this mechanical strength of stationary ring, the working life of increase stationary ring.
