Abstract
The utility model discloses a water pump impeller for an outboard engine. The water pump impeller comprises a framework, key grooves are formed in an inner hole of the framework along the axial direction; a rubber layer is wrapped outside the framework, blades which are evenly arranged along the peripheral direction are arranged on the excircle portion of the rubber layer, and the water pump impeller is characterized in that a distance between the outer ends of the blades and a circle center of the inner hole of the framework is 45-60mm, the diameter of the inner hole of the framework is 15-25mm, and the height (H) of the framework is 18-21mm. Dimension parameters of the water pump impeller for the outboard engine are designed again, accordingly water pumping quantity of a water pump of the outboard engine with the water pump impeller can be well matched with a boat machine, technical problems are solved, and the water pump impeller is applicable to popularization and application.
Description
Technical field
The utility model belongs to a kind of pump part, specifically, relates in particular to the water pump vane for outboard machine.
Background technique
Impeller is a kind of significant components on the water pump, and the parameters such as size of the pump water yield of water pump and impeller are closely related.At present, we are in the design outboard machine, and the ready-made water pump of common procurement is ship pump water.Yet in use, we find that the water pump pump water yield of outsourcing can not be complementary with the ship machine; For this reason, we have designed the water pump vane that is used for outboard machine, in order to the pump water yield of water pump and the cooling water requirement of ship machine are complementary.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of water pump vane for outboard machine, in order to the pump water yield of water pump and the pump water yield of ship machine are complementary.
The technical solution of the utility model is as follows: a kind of water pump vane for outboard machine, comprise skeleton (1), and have keyway (1a) on the endoporus of this skeleton (1) vertically; Described skeleton (1) is wrapped with rubber layer (2), the excircle part of this rubber layer (2) is the blade (2a) that evenly arranges along circumferentially, it is characterized in that: the outer end of described blade (2a) is 45～60mm to the distance (R) in skeleton (1) the endoporus center of circle, the diameter (D) of this skeleton (1) endoporus is 15～25mm, and the height (H) of skeleton (1) is 18～21mm.
The utility model is on the basis of existing structure, suitably adjusted the dimensional parameters that is used for the water pump vane of outboard machine, and the outer end of described blade (2a) is designed to 45～60mm to the distance (R) in skeleton (1) the endoporus center of circle, the diameter (D) of this skeleton (1) endoporus is designed to 15～25mm, and the height (H) of skeleton (1) is designed to 18～21mm.
Show that through test the water pump pump water yield that the outboard machine of this water pump vane is housed can be complementary with the ship machine well, has solved technical barrier, is suitable for promoting the use.
As optimal design, the width of described keyway (1a) is 2.5～5mm, and the degree of depth is 1.3～1.5mm.
In the present embodiment, described distance (R) is 52mm, and the diameter (D) of skeleton (1) endoporus is 20mm, and the height (H) of skeleton (1) is 19mm.
In the utility model, described skeleton (1) is made by brass.
As preferably, the width of described keyway (1a) is 3mm, and the degree of depth is 1.4mm.
Beneficial effect: the utility model has redesigned and has been used for the dimensional parameters of the water pump vane of outboard machine, thereby the water pump pump water yield of the outboard machine that this water pump vane is housed can be complementary with the ship machine well, has solved technical barrier well, is suitable for promoting the use.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional view of Fig. 1;
Fig. 3 is the structural representation of skeleton 1 among Fig. 2.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, 2, 3, a kind of water pump vane for outboard machine comprises skeleton 1, and this skeleton 1 is made by brass, and the diameter D of skeleton 1 endoporus is 15～25mm, and is optimized for 20mm.And the height H of described skeleton 1 is 18～21mm, and is preferably 19mm.In addition, have keyway 1a on the endoporus of skeleton 1 vertically, this keyway 1a runs through the upper and lower surface of skeleton 1.The degree of depth of above-mentioned keyway 1a is 1.3～1.5mm, and is preferably 1.4mm, and its width is 2.5～5mm, and is preferably 3mm.
Be wrapped with rubber layer 2 at above-mentioned skeleton 1, the excircle part of this rubber layer 2 is the blade 2a that arranges along circumferentially evenly, and the Placement of the structure of rubber layer 2 and rubber layer 2 and skeleton 1 all adopts existing structure, does not do at this and gives unnecessary details.The outer end of described blade 2a is 45～60mm to the distance R in the skeleton 1 endoporus center of circle, and is preferably 52mm,
The above only is preferred embodiment of the present utility model; it is not restriction with the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
