Abstract
The utility model relates to a novel water pump impeller sealing device, which comprises an impeller, a pump and a gasket ring and is characterized in that an annular convex part is arranged on the impeller. One surface of an annular sealing surface is arranged with an annular groove concentric with the gasket ring. The annular groove on the gasket ring is positioned towards the annular convex part of the impeller. A clearance is arranged between the annular groove on the gasket ring and the annular convex part of the impeller. In addition, an inlet and an outlet of the clearance between the annular groove on the gasket ring and the annular convex part of the impeller are positioned on the same side. The utility model has the advantages of improving pump working efficiency, steam corrosion resistance and pump performance approximate to lower flow rate and eliminating peaks of pump flow and lift curve.
Description
Technical field
The utility model relates to a kind of pump seal structure, particularly a kind of novel water pump vane seal arrangement.
Background technique
During pump work, by impeller liquid is done work, there are fluid pressure differential in impeller outlet place and inlet, make a part of liquid by impeller from pump chamber through the impeller seals czermak space to the impeller inlet adverse current.Sealing ring gap is less in the prior art, and adverse current is vertical to collision with the main flow at impeller inlet place, causes impeller inlet place liquid stream disorderly, has reduced the anti-cavitation ability of pump, causes the low and poor reliability of efficient of pump.
Summary of the invention
The purpose of this utility model provides a kind of novel water pump gland, has solved the poor reliability and the anti-cavitation ability problem of pump in the prior art.A kind of novel water pump vane seal arrangement comprises impeller, the pump housing, seal ring, it is characterized in that: annular projection is arranged on the impeller, and seal ring has the annular groove with the seal ring concentric on the one side of impeller, and the annular groove on the seal ring is corresponding with the circular protrusion of impeller.Have the gap between the annular groove on the seal ring and the circular protrusion of impeller, the inlet and the outlet in the gap between the annular groove on the seal ring and the circular protrusion of impeller are positioned at the same side.The utility model has the advantages that the working efficiency and the anti-cavitation ability that have improved pump, improve near the performance of pump small flow, that has eliminated pump duty, head curve carries the peak phenomenon on the back.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated.
Accompanying drawing 1 is the cross-sectional view of prior art.
Accompanying drawing 2 is a cross-sectional view of the present utility model.
Embodiment
Comprise a kind of novel water pump vane seal arrangement among the figure, comprise impeller 1, the pump housing 2, seal ring 3, it is characterized in that: annular projection 4 is arranged on the impeller 1, seal ring 3 has the annular groove 5 with seal ring 3 concentrics on the one side of impeller 1, and the annular groove 5 on the seal ring 3 is corresponding with the circular protrusion 3 of impeller 1.Have gap 6 between the annular groove 5 on the seal ring 3 and the circular protrusion 3 of impeller 1, the inlet and the outlet in the gap 6 between the annular groove 5 on the seal ring 3 and the circular protrusion 3 of impeller 1 are positioned at the same side.
During pump working, a fluid stream that leaks to impeller 1 import from impeller 1 outlet is consistent with impeller 1 main liquid stream, makes impeller 1 import liquid stream stable and uniform, and can improve the anti-cavitation ability of water pump, and the net positive suction head of water pump is reduced; Because seal ring 3 forms a ring nozzle with impeller 1 import, the liquid of Guo Louing is passed to impeller 1 import master liquid stream with energy from here, the liquid energy that leaks from seal ring 3 has reclaimed a part, the efficient of water pump can improve about 2%, and can alleviate water pump water pump secondary back in the impeller 1 when low flow rate condition particularly under off-design behaviour, improve water pump at the lift that closes the dead point, thus eliminate head curve carry the peak phenomenon on the back.
Claims (3)
1. a novel water pump vane seal arrangement comprises impeller, the pump housing, seal ring, it is characterized in that: annular projection is arranged on the impeller, and seal ring has the annular groove with the seal ring concentric on the one side of impeller, and the annular groove on the seal ring is corresponding with the circular protrusion of impeller.
2. a kind of novel water pump vane seal arrangement as claimed in claim 1 is characterized in that: have the gap between the annular groove on the seal ring and the circular protrusion of impeller.
