Abstract
The utility model discloses a double power sealing disc for a pump. The double power sealing disc for the pump comprises an inner side power sealing wheel (1), an inner side power sealing wheel sealing protective cover (3), an outer side power sealing wheel (2) and an outer side power sealing wheel sealing protective cover (4). The inner side power sealing wheel (1) is installed in the inner side power sealing wheel sealing protective cover (3). The outer side power sealing wheel (2) is installed between the inner side power sealing wheel sealing protective cover (3) and the outer side power sealing wheel sealing protective cover (4). The double power sealing disc for the pump can effectively avoid the phenomenon of material leakage due to insufficient vacuum degree when the pump is operated in a low speed mode.
Description
Technical field
The utility model relates to a kind of pump, the double dynamical seal disc of particularly a kind of pump.
Background technique
At present, the most of single action power seal disc that adopts of pump seals, still, when being sealed in low cruise, single action power seal disc often expects phenomenon because leakage appears in degree of vacuum inadequately, not only cause the waste of resource, also make the increase of user cost, be unfavorable for applying of pump.
Summary of the invention
The utility model at tradition adopt pump that single action power seal disc seals when the low cruise often because the phenomenon that material appears leaking in degree of vacuum inadequately, the utility model provides a kind of pump double dynamical seal disc, the phenomenon that can effectively avoid pump to occur leaking material inadequately because of degree of vacuum when low cruise.
To achieve these goals, the utility model adopts following technological scheme:
The double dynamical seal disc of a kind of pump, described pump comprises inboard dynamic seal wheel, inboard dynamic seal wheel sealing protecting cover, outside dynamic seal wheel and outside dynamic seal wheel sealing protecting cover with double dynamical seal disc, described inboard dynamic seal wheel is installed in the inboard dynamic seal wheel sealing protecting cover, and dynamic seal wheel in the described outside is installed in the middle of inboard dynamic seal wheel sealing protecting cover and the outside dynamic seal wheel sealing protecting cover.
The utility model provides the beneficial effect of technological scheme to be: the double dynamical seal disc of pump provided by the utility model, the phenomenon that can effectively avoid pump to occur leaking material inadequately because of degree of vacuum when low cruise.
Description of drawings
Fig. 1 is the sectional view of the utility model pump with double dynamical seal disc.
Description of reference numerals:
The inboard dynamic seal wheel of 1-; 2-outside dynamic seal wheel; The inboard dynamic seal wheel of 3-sealing protecting cover;
4-outside dynamic seal wheel sealing protecting cover
Embodiment
For making the purpose of this utility model, technological scheme and beneficial effect clearer, the utility model mode of execution is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model provides a kind of pump double dynamical seal disc, described pump comprises inboard dynamic seal wheel 1 with double dynamical seal disc, inboard dynamic seal wheel sealing protecting cover 3, outside dynamic seal wheel 2 and outside dynamic seal wheel sealing protecting cover 4, described inboard dynamic seal wheel 1 is installed in the inboard dynamic seal wheel sealing protecting cover 3, described outside dynamic seal wheel 2 is installed in the middle of inboard dynamic seal wheel sealing protecting cover 3 and the outside dynamic seal wheel sealing protecting cover 4, when pump is driven, inboard dynamic seal wheel 1 and outside dynamic seal wheel 2 are worked simultaneously, can produce vacuum in the inboard dynamic seal wheel sealing protecting cover 3 and in the outside dynamic seal wheel sealing protecting cover 4, even both low-speed motions, also can guarantee the degree of vacuum that pump is enough, the material phenomenon can not occur leaking.
The utility model protection domain is not limited to above-mentioned example, and every technology distortion of being done according to the technology of the present invention principle all falls within protection scope of the present invention.
