Description
Technical field
The present invention relates to diving pump technical fields, more particularly to a kind of novel diving with impeller floating equilibrium structure
Pump.
Background technique
Immersible pump is the important equipment of deep-well water lift.Entire unit pulls the plug work when use, and underground water is extracted
Earth's surface is that domestic water, mine are speedily carried out rescue work, industry cooling, field irrigation, seawater lift, steamer tune carry, it may also be used for fountain scape
It sees.Currently, the impeller of most immersible pumps is all fixed on pump shaft, structure is complicated, and assembly time is long.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of novel immersible pumps with impeller floating equilibrium structure, can limit leaf
Wheel has the function that balance impeller between two balance weights, while can guarantee that the good performance of impeller is not destroyed, and has and is not necessarily to
The advantages of fixed impeller, structure is simple, easy to assembly, saves assembly time.
In order to solve the above technical problems, the technical solution adopted by the present invention is that: it is a kind of novel with impeller floating equilibrium knot
The immersible pump of structure, the immersible pump include the pump housing, submersible motor and are located at the intracorporal pump shaft of the pump and impeller, further include running through
The blower inlet casing of the pump shaft, the pump housing lower end are equipped with water inlet joint, and the immersible pump further includes the cunning being fixed on the pump shaft
Set, the impeller can slide on the sliding sleeve, and sliding sleeve can control all impellers and slide on pump shaft as a whole, institute
It states and is equipped with balanced structure in the pump housing, the balanced structure can limit the impeller and float up and down.
Further, the blower inlet casing is fixed on the shell of the pump housing by fastener.
Further, the balance weight includes positioned at the upper balance weight on the blower inlet casing top and positioned at the blower inlet casing bottom
Lower balance weight, the impeller can float between the upper balance weight and the lower balance weight.
Further, the pump housing upper end is equipped with non-return valve.
Further, floating space of the impeller between the upper balance weight and the lower balance weight is 5-50mm.
The advantages and positive effects of the present invention are: the balanced structure in the present invention can limit impeller two balance weights it
Between, have the function that balance impeller, while can guarantee that the good performance of impeller is not destroyed；The present invention also has without fixed leaf
The advantages of wheel, structure is simple, easy to assembly, saves assembly time；Impeller is controlled by the balanced structure to float on a small quantity, it can also be with
Play the role of compression buffering.

Specific embodiment
Specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
As shown in Figs. 1-2, a kind of novel immersible pump with impeller floating equilibrium structure, the immersible pump include the pump housing 1,
Submersible motor 6 and pump shaft 2 and impeller 3 in the pump housing 1 further include the blower inlet casing 7 through the pump shaft 2, the pump
1 lower end of body is equipped with water inlet joint 11, and the immersible pump further includes the sliding sleeve 9 being fixed on the pump shaft 2, and the impeller 3 can be in institute
It states and is slided on sliding sleeve 9, be equipped with balanced structure in the pump housing 1, the balanced structure can limit the impeller 3 and float up and down.
In one embodiment of the present of invention, the blower inlet casing 7 is fixed on the shell of the pump housing 1 by fastener, just
In installation and removal.The balanced structure includes upper balance weight 5 and lower balance weight 10, and the upper balance weight is located at the blower inlet casing
In the seam allowance plane that 7 tops are contacted with the impeller 3, the lower balance weight 10 is located at 7 bottom of blower inlet casing and the impeller 3
In the seam allowance plane of contact, the impeller 3 can float between the upper balance weight 5 and the lower balance weight 10.The pump housing 1
Upper end is equipped with non-return valve 4.Floating space of the impeller 3 between the upper balance weight 5 and the lower balance weight 10 is 5-
50mm。
The impeller 3 is controlled in the upper balance weight 5 and the lower balance weight 10 by the balanced structure in the present invention
Between float on a small quantity, the sliding sleeve 9 can control all impellers 3 and slide on pump shaft 2 as a whole, make each impeller
Slippage and sliding effect are consistent.
The embodiments of the present invention have been described in detail above, but content is only the preferred embodiment of the present invention,
It should not be considered as limiting the scope of the invention.All changes and improvements made in accordance with the scope of the present invention, should all
It still belongs within this patent covering scope.
