Description
Technical field:
The utility model relates to a kind of self-balanced mechanical seal device that is applicable in the pump that contains solid particle and high viscosity medium and other machinery.
Background technique:
At present, notice of authorization number discloses dress self-balanced mechanical seal device in a kind of many springs for the model utility of CN2560795Y, and this mechanical seal device mainly comprises rotating ring, rotating seat, stationary ring, axle, drive sleeve and a plurality of spring; Described rotating ring is installed in rotating seat; Described drive sleeve is fixed on the axle by Cock screw; Described drive sleeve is provided with a seal groove with the inner wall surface that axle matches; Be placed with one and the close-fitting axle envelope of an axle O type circle in the described seal groove; The inner chamber of described rotating seat afterbody outer wall and described drive sleeve forms the slip plane that cooperatively interacts; Offer seal groove on the slip plane of described drive sleeve, be placed with in the described seal groove and the close-fitting rotating ring O of rotating ring slip plane type circle; Described drive sleeve is provided with a plurality of spring eyes that are used for placing spring, and described spring withstands between spring eye and the rotating seat; Be equipped with driving pin on the described drive sleeve, an end of described driving pin is positioned at the pin-and-hole that is arranged on rotating seat; The working surface of described rotating ring and the working surface of stationary ring are fitted.Though the mechanical seal device of said structure is replaced whole big spring of the prior art by a plurality of springs of parallel axes with axle are set between drive sleeve and rotating seat, thereby solve the prior art mechanical seal device influences sealing effect because of rotating ring and stationary ring sealing surface discontinuity problem, but still there is a deficiency in it: when moving ring assembly rotates, mechanical seal device can produce a large amount of heats because of friction, under the influence of heat of medium own and fricative heat, since be installed in together rotating seat and the expansion coefficient of rotating ring be different, therefore, above-mentioned mechanical seal device is easy to take place because of degrees of expansion is inconsistent deformation, come off thereby cause on the driven ring seat of rotating ring, have a strong impact on the proper functioning of mechanical seal device.
The model utility content:
The technical problems to be solved in the utility model is, provide a kind of rotating ring and stationary ring sealing surface of not only can guaranteeing stressed evenly, and heatproof degree impact is strong, and deformation quantity is little, thus the self-balanced mechanical seal device of effectively avoiding rotating ring to come off.
Technical solution of the present utility model is, a kind of self-balanced mechanical seal device with following structure is provided, and it comprises rotating ring, stationary ring, drive sleeve and a plurality of spring; Described drive sleeve is fixed on the axle by Cock screw; The working surface of described rotating ring and the working surface of stationary ring are fitted; Described drive sleeve is provided with a plurality of spring eyes that are used for placing spring; Be equipped with driving pin on the described drive sleeve; The inner chamber of described rotating ring afterbody outer wall and described drive sleeve forms the slip plane that cooperatively interacts; Be provided with rotating ring O type circle between described rotating ring and the drive sleeve; Described spring withstands between spring eye and the rotating ring; Described rotating ring is provided with the transmission pin-and-hole; One end of described driving pin is positioned at the transmission pin-and-hole.
After adopting above structure, compared with prior art, the utlity model has following advantage: be installed on the rotating seat different with rotating ring in the prior art, the utility model has saved rotating seat, and directly offers the transmission pin-and-hole on rotating ring, because rotating ring does not have and the rotating seat insert, therefore, the heatproof degree impact of the utility model self-balancing mechanical sealing device strengthens greatly, and deformation quantity reduces greatly, has effectively avoided coming off of rotating ring; In addition, the same with prior art, the utility model has also adopted the mode that a plurality of springs are set between drive sleeve and rotating ring, and therefore, the utility model has kept prior art can guarantee rotating ring and the stressed advantage of uniform of stationary ring sealing surface.
As a kind of improvement of the present utility model, the utility model also comprises stop pin; Described stationary ring is provided with lock pin aperture; One end of described stop pin is connected on the pump housing, and its other end is positioned at lock pin aperture.Because under the mechanical seal working state, the working surface of stationary ring and the working surface of rotating ring are fitted all the time, and rotating ring is to be in rotation shape body, therefore, under the effect of frictional force, the rotating ring of rotation will drive stationary ring and rotates together, and being provided with of the utility model stop pin can be played the effect that stops stationary ring to rotate, thereby further improves stressed even of rotating ring and stationary ring sealing surface.
