Abstract
The utility model discloses an integrated mechanical sealing device which comprises a rotation shaft, a sealing base, a press cover, a movable ring assembly with a movable ring and a static ring assembly with a static ring, and is characterized in that the inside of the sealing end of the movable ring is provided with a plurality of liquid grooves communicated with the inside of the movable ring and arranged obliquely according to the same rotation direction as the movable ring, the rotation direction of the liquid groove is the same as that of the movable ring; with the further improvement of the utility model, the sealing end of the movable ring is provided with a plurality of holes, the holes are provided inside with a solid lubricant, the sealing base is fixed with a mechanical sealing shell, the movable ring and the static ring are both arranged inside the mechanical sealing shell. The utility model can effectively prevent impurities from entering the sealing surface and improve the lubrication condition of the sealing surface so as to prolong the service life of the device, and the internal structure can be kept in sealed state.
Description
Technical field
The utility model relates to a kind of integrated mechanical sealing device.
Background technique
Be widely used in now that integrated mechanical sealing device on the slag stock pump comprises rotating shaft, sealing seat, gland, the moving ring assembly of the rotating ring that has and have static components of stationary ring etc., because the impurity that contains in the slag slurry is more, impurity more easily enters sealing surface, and sealing surface does not have other structure of improving lubrication state, cause very quick-wearing of dynamic and static ring, shortened the working life of seal arrangement.
The model utility content
The purpose of this utility model is the above-mentioned deficiency at prior art, provides a kind of impurity that can effectively prevent to enter sealing surface and the whole integrated mechanical sealing device that improves the sealing surface lubrication state, and it has the advantage of long service life.
For achieving the above object, whole integrated mechanical sealing device of the present utility model, the moving ring assembly of the rotating ring that comprise rotating shaft, sealing seat, gland, has and have the static components of stationary ring, it is characterized in that being provided with in the inboard of rotating ring seal face the liquid bath that several are communicated with the rotating ring inner side surface and are obliquely installed by same rotation direction, the rotation direction of liquid bath is identical with turning to of rotating ring; When the rotating ring rotation, drive the liquid that is stored in several liquid baths and rotate the outside eddy current of formation together during work, can prevent effectively that impurity from entering sealing surface, thereby reduce wear;
As further improvement of the utility model, on the rotating ring seal face, also be provided with several holes, be provided with the solid lubrication thing in the hole, as graphite, can improve the sealing surface lubrication state, further reduce wear;
As further improvement of the utility model, on sealing seat, set firmly organic capsule body, rotating ring and stationary ring all are positioned at machine capsule body, the seal arrangement collection are adorned as a whole, can prevent that the imitator from understanding the internal structure of seal arrangement, reaches secret purpose;
In sum, the utility model can prevent effectively that impurity from entering sealing surface and improving the sealing surface lubrication state, thereby prolongs its working life, and internal structure is maintained secrecy.
