Abstract
The utility model discloses a cooling liquid sealing device on the mechanical seal atmosphere side of a plastic pump. The cooling liquid sealing device comprises an impeller, a movable ring, a static ring and a static ring gland, wherein the movable ring is installed on the impeller, and the static ring is installed on the static ring gland and matched with the movable ring; a framework oil seal is arranged on the face, matched with the impeller, of the static ring gland and provided with a circle of groove, and the groove is provided with an abrasion-resistant sleeve. The cooling liquid sealing device has the advantages that due to the fact that the framework oil seal and the high-hardness abrasion-resistant sleeve are matched for sealing cooling liquid on the mechanical seal atmosphere side of one single end face of the plastic pump, the sealing service life is prolonged by four times to five times.
Description
Technical field
The utility model relates to a kind of cooling liquid seal arrangement, and more specifically, it relates to a kind of plastic pump mechanical seal atmospheric side cooling liquid seal arrangement.
Background technique
Under the operating mode that medium easily fans the air in carrying high temperature strong acid, pump chamber, it is cooling that single mechanical end face seal atmospheric side needs cooling liquid to carry out, to protect mechanical seal.The rotor of prior art High Rotation Speed and the fitting surface of outside framework oil seal are easy to wear, cause stabilization of equipment performance to decline, and the life-span shortens.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of rational in infrastructure, and fitting surface is not easy to wear, and the life-span is long, the plastic pump mechanical seal atmospheric side cooling liquid seal arrangement of good stability.
The purpose of this utility model is achieved through the following technical solutions: this plastic pump mechanical seal atmospheric side cooling liquid seal arrangement, comprise impeller, rotating ring, stationary ring and seal end plate, described rotating ring is arranged on impeller, and stationary ring is arranged on seal end plate and with rotating ring and matches; Described seal end plate and impeller fitting surface are provided with outside framework oil seal, and described outside framework oil seal is provided with a circle groove, and described groove is provided with wear-resistant sleeve.
As preferably: the side of described wear-resistant sleeve is provided with wear-resisting block set.
As preferably: described wear-resistant sleeve adopts 88～92HRA high hardness to inlay wear-resistant sleeve.
The beneficial effects of the utility model are: by plastic pump single mechanical end face seal atmospheric side cooling liquid, adopt outside framework oil seal to coordinate and seal with high hardness wear-resisting cover, make to extend sealing life 4～5 times.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Description of reference numerals: rotating ring 1, stationary ring 2, outside framework oil seal 3, wear-resistant sleeve 4, wear-resisting block set 5, impeller 6, seal end plate 7.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.Although the utility model is described in connection with preferred embodiment, should know, do not represent that the utility model is limited in described embodiment.On the contrary, the utility model is by alternative, modified model and the equivalent contained in the scope of the present utility model that can be included in attached claims restriction.
As shown in Figure 1, this plastic pump mechanical seal atmospheric side cooling liquid seal arrangement, comprises impeller 6, rotating ring 1, stationary ring 2 and seal end plate 7, and described rotating ring 1 is arranged on impeller 6, and stationary ring 2 is arranged on seal end plate 7 and with rotating ring 1 and matches; Described seal end plate 7 and impeller 6 fitting surfaces are provided with outside framework oil seal 3, and described outside framework oil seal 3 is provided with a circle groove, and described groove is provided with wear-resistant sleeve 4.Described wear-resistant sleeve 4 adopts 88～92HRA high hardness to inlay wear-resistant sleeve, and the side of described wear-resistant sleeve 4 is provided with wear-resisting block set 5.
By plastic pump single mechanical end face seal atmospheric side cooling liquid, adopt outside framework oil seal to coordinate and seal with high hardness wear-resisting cover, make to extend sealing life 4～5 times.
