Embodiment
It should be noted that in the case where not colliding, the feature in embodiment and embodiment in the invention
It can be mutually combined.
The specific embodiment of the invention is elaborated below in conjunction with the accompanying drawings.
A kind of high stability single blade screw centrifugal, as shown in Figures 1 to 3, including the pump housing 1 and it is arranged on pump housing inner chamber
Impeller 2；The pump housing 1 is provided with suction inlet 3, outlet 4 and pump shaft 5；The impeller 2 is provided with close to one end of pump shaft 5
Impeller base 6；Described one end of pump shaft 5 is stretched into the pump housing 1 and is connected with impeller base 6, and the other end stretches out the pump housing 1 and filled with external impetus
The output axis connection put；The impeller 2 is provided with helical blade 7, and reinforcing ring 8 is provided with the front end of helical blade 7；The reinforcement
Ring 8 is provided with the first balanced adjustment part 9, and the second balanced adjustment part 10 is provided with impeller base.In the axis and impeller of pump shaft
At heart line, impeller base centerline on the same line, the stability of impeller work is farthest ensure that from structure.
In an optional embodiment, the above-mentioned inwall of reinforcing ring 8 is provided with installation annular groove 11, the first balanced adjustment part
It is fixed on by connector 12 in installation annular groove 11.Specifically, connector can be attachment screw either magnetic part or
Tensioner part, connector can realize stable connection, and the connected mode of structural member is prior art, no longer superfluous here
State.It is pointed out that selected connector, it is desirable to continuously adjusted in installation annular groove, make the first balanced adjustment part
The slidable continuous adjustment position in installation annular groove.To meet the needs of impeller balance adjustment.
In another optional embodiment, the above-mentioned inwall of reinforcing ring 8 is provided with installation annular groove 11；First balanced adjustment
