Preferably, the pump shaft is equipped with mirror surface.
Preferably, the transfer port communication seals chamber, the gas in seal chamber are nitrogen.
The beneficial effects of the utility model are: the utility model uses the nitrogen for filling high pressure into seal chamber, high pressure nitrogen
It being sealed as supplement tetrafluoro restrictor ring between pump shaft and water ring wheel, sealing effect is good, without being replaced to sealing element,
It is non-maintaining to sealing element, it ensure that the stable operation of self priming pump, avoid the shutdown of the self priming pump as caused by seal failure,
It is effectively guaranteed and continues efficiently to convey operation.
Detailed description of the invention
Fig. 1 is the schematic view of the front view of the utility model；
In figure: 1 pump shaft, 11 mirror surfaces, 2 pump covers, 3 seal chambers, 31 boss, 32 tetrafluoro restrictor rings, 33 transfer ports, 4 water ring wheels,

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
It clearly and completely describes, it is clear that described embodiments are only a part of the embodiments of the present invention, rather than whole implementation
Example.The component of the utility model embodiment being usually described and illustrated herein in the accompanying drawings can carry out cloth with a variety of different configurations
Install meter.Therefore, requirement is not intended to limit to the detailed description of the embodiments of the present invention provided in the accompanying drawings below
The scope of the utility model is protected, but is merely representative of the selected embodiment of the utility model.Implementation based on the utility model
Example, those skilled in the art's every other embodiment obtained without making creative work belong to this
The range of utility model protection.
As an example, as shown in Figure 1, a kind of novel sealing structure of self priming pump, structure feature are, including, pump shaft
1, pump shaft 1 can be equipped with pump cover 2 outside, seal chamber 3 can be equipped between pump shaft 1 and pump cover 2, the left end of seal chamber 3 can be equipped with water
Ring wheel 4, the right end of seal chamber 3 can be equipped with bearing arrangement 5, and seal chamber 3 and the junction of water ring wheel 4 can be equipped with boss 31,
The other side of boss 31 can be equipped with tetrafluoro restrictor ring 32, and the lower part of seal chamber 3 can be equipped with transfer port 33.
Further, the junction of the bearing arrangement 5 and seal chamber 3 can be equipped with bearing gland 51.
Further, bearing seal ring 52 can be equipped in the bearing gland 51, the right side of the bearing gland 51 can be with
Equipped with gasket 53.
Further, the right side of the pump cover 2 can be equipped with bearing frame body 6, and the junction of pump cover 2 and bearing frame body 6 can be with
Equipped with sealing ring 61.
Further, mirror surface 11 can be equipped on the pump shaft 1.
Further, the transfer port 33 can be filled with nitrogen into seal chamber 3 with communication seals chamber 3.
In the specific embodiment of the utility model, nitrogen is filled with into seal chamber 3 by transfer port 33, and bear one
Tetrafluoro restrictor ring 32 is pushed against on boss 31 by the nitrogen of fixed air pressure, negative pressure, and pump shaft 1 is mirror surface 11, expanded tetrafluoro section
