Abstract
The utility model relates to the field of drainage pumps, in particular to an air conditioner drainage pump impeller. The air conditioner drainage pump impeller comprises a main shaft, a plurality of main blades, a flow stabilizing ring and flow deflectors. The main blades evenly radiate from the main shaft, the outer ends of the main blades are connected with the flow stabilizing ring, the flow deflectors are distributed in a sector shape in the area formed by the main blades and the flow stabilizing ring, gaps are reserved between the flow defectors and the main shaft, the distances between the two end points of the outer arc of each flow deflector and the top of the flow stabilizing ring respectively are a and b, b is larger than or equal to 1/5 a and is smaller than or equal to 2/3 a, the inner arc of each flow deflector is lower than any end point of the outer arc, and all the flow defectors are tilted. Due to the adoption of the structure, the drainage efficiency of an air conditioning drainage pump is improved.
Description
Technical field
The utility model relates to draining pump field, refers in particular to a kind of impeller for air conditioning draining pump.
Background technique
Air-conditioning drainage pump is the device for air conditioner condensate water draining, and existing impeller for air conditioning draining pump is generally made up of a main shaft, some primary blades, back blades and current stabilization ring, and primary blades is radial being uniformly distributed centered by main shaft, and its outer end is connected with current stabilization ring; Back blades structure is similar to primary blades, and it is positioned under main shaft, and length of blade is less than primary blades.
When work, back blades is immersed in the water, and impeller spindle drives selection by motor shaft, by centrifugal force and pressure difference, water is sucked in the pump housing.But in this kind of structure, easily fallen after rise by the water capacity after sucting, reduced drainage efficiency.
Therefore, the inventor makes further research this, develops a kind of impeller for air conditioning draining pump, and this case produces thus.
Model utility content
The purpose of this utility model is to provide a kind of impeller for air conditioning draining pump, has improved the drainage efficiency of air-conditioning drainage pump.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of impeller for air conditioning draining pump, comprises main shaft, some primary blades, current stabilization ring, guide plate; Primary blades is radial being uniformly distributed centered by main shaft, and primary blades outer end is connected with current stabilization ring; Described guide plate is fan-shaped distribution in the region being formed by primary blades and current stabilization ring, and guide plate leaves gap between main shaft, two end points of guide plate outer arc are respectively a and b to the distance at current stabilization ring top, and 1/5a≤b≤2/3a, the inner arc of guide plate is lower than the end points of arbitrary outer arc, and whole guide plate is skewed.
Further, described b=1/3a.
Further, described primary blades can be linear, can be also arc line type.
Further, described primary blades or be connected with main shaft, or and main shaft between gapped, above-mentioned two kinds of modes are for being crisscross arranged.
Further, the quantity of described primary blades is 8, and wherein 4 are connected to form cross configuration with main shaft, and the distance that remains 4 and main shaft interval equals the distance between guide plate and main shaft.
Adopt after such scheme, the utility model compared with prior art, has the following advantages:
Avoid the falling of water, and by the refluence ring of tilting, can cause the pressure difference between current, increased the pressure rising, improved drainage efficiency.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is the plan view of Fig. 1.
Label declaration
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
As shown in the figure, a kind of impeller for air conditioning draining pump that the utility model discloses, comprises main shaft 1, primary blades 2, back blades 3, current stabilization ring 4, guide plate 5; Primary blades 2, take main shaft 1 as axle center, is radial and is uniformly distributed, and primary blades 2 outer ends are connected with current stabilization ring 4, and the structure of primary blades 2 can be selected straight line type, can be also arc line type.Primary blades 2 or be connected with main shaft 1, or and main shaft 1 between gapped, above-mentioned two kinds of modes are for being crisscross arranged.The below of main shaft 1 is back blades 3, and the length of back blades 3 is less than primary blades 2.
Described guide plate 5 is fan-shaped distribution in the region being formed by primary blades 2 and current stabilization ring 4, and guide plate 5 also leaves gap between main shaft 1, two end points of guide plate 5 outer arcs 52 are respectively a and b to the distance at current stabilization ring 4 tops, preferably b=1/3a, the inner arc 51 of guide plate 5 is lower than the end points of arbitrary outer arc 52, and whole guide plate 5 is skewed.
In Fig. 1, the sense of rotation of impeller is to select counterclockwise, the gap of water between guide plate 5 inner arcs 51 and main shaft 1 enters, because the water velocity of outer arc 52 is greater than inner arc 51, so the hydraulic pressure of inner arc 51 is greater than the hydraulic pressure of outer arc 52, this pressure and centrifugal force one react on the water in guide plate 5, and the raising efficiency of current is greatly improved.
Above are only specific embodiment of the utility model, but design concept of the present utility model is not limited to this, allly utilizes this design to carry out the change of unsubstantiality to the utility model, all should belong to the behavior of invading the utility model protection domain.
