Abstract
The utility model discloses an impeller used for a pipeline centrifugal pump. The impeller used for the pipeline centrifugal pump comprises an upper cover plate and a lower cover plate which are arranged to form a circular shape. The center of the upper cover plate is provided with a center hole, the center of the lower cover plate is provided with a hole with a turned edge, a cavity is formed between the upper cover plate and the lower cover plate, and a plurality of same arc-shaped blades are evenly distributed in the cavity. The upper cover plate, the lower cover plate and the blades are formed by sheet materials through precision stamping, and the impeller is synthesized through resistance welding by means of a fixture. According to the impeller used for the pipeline centrifugal pump, the blades generate eight water streams under the action of centrifugal force, the centrifugal force is enhanced, a water channel is smooth, no resistance exists, the impeller efficiency is improved, and the impeller is good in dynamic balance because the impeller is formed through stamping, high in production efficiency, low in cost and small in electricity consumption.
Description
Technical field
The utility model relates to a kind of Piping Centrifugal Pumps impeller.
Background technique
Existing Piping Centrifugal Pumps impeller is cast body, rough surface, and resistance is large, and dynamic balancing is poor, impeller weight, workload is large; Blade is 6 equal portions discharges, and impeller adiabatic efficiency is low, and manufacturing efficiency is low, and cost of production is high, and electric consumption is many.
Model utility content
The technical problems to be solved in the utility model is the defect that overcomes prior art, provides a kind of manufacturing efficiency high, and cost is low, good dynamic balance, the Piping Centrifugal Pumps impeller of energy saving.
In order to solve the problems of the technologies described above, the utility model provides following technological scheme:
A kind of Piping Centrifugal Pumps impeller of the utility model, it comprises upper cover plate and the lower cover plate of all rounded settings, described upper cover plate center is provided with center hole, described lower cover plate center is set to the hole of flange, between described upper cover plate and described lower cover plate, form cavity, in described cavity, be evenly equipped with the blade of some identical arcs.Upper cover plate, lower cover plate and blade all form with sheet material precision stamping, then with fixture through the synthetic impeller of resistance welding.
Further, described blade is set to 8.
The beneficial effect that the utility model reaches is:
The Piping Centrifugal Pumps impeller that the utility model provides, there are 8 current in blade, increase centrifugal force under the effect of centrifugal force, and water channel is smooth, and non-resistance improves impeller adiabatic efficiency, and because of drawing good dynamic balance, manufacturing efficiency is high, and cost is low, and electric consumption is few.
Brief description of the drawings
Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for specification, is used from explanation the utility model with embodiment one of the present utility model, does not form restriction of the present utility model.In the accompanying drawings:
