Abstract
The utility model relates to an impeller, and discloses an efficient energy-saving centrifugal pump impeller which is composed of an upper cover plate, a lower cover plate and more than one blade. A shaft sleeve hole is formed in the center of the upper cover plate, and a suction hole is coaxially formed in the lower cover plate. More than one involute blade is evenly distributed between the upper cover plate and the lower cover plate, discharging outlets are formed among the upper cover plate, the lower cover plate and the far ends of two adjacent involute blades, and speed-up protruding blocks are evenly distributed on the outer arc faces of the involute blades. According to the efficient energy-saving centrifugal pump impeller, the inside of the impeller and the surfaces of radioactive arc separation plates are uneven, so that friction force between the impeller and water in the rotating process is strengthened, work efficiency of a centrifugal pump is improved, and the energy-conserving and efficient purposes are achieved.
Description
Technical field
The utility model relates to a kind of impeller, relates in particular to a kind of high-efficient energy-saving centrifugal pump impeller.
Background technique
Pump is the machinery of carrying liquid or making the liquid supercharging.It sends motive mechanical energy or other external energies to liquid, so that liquid energy increases, be mainly used to carry and comprise water, wet goods, centrifugal pump is to use very widely pump, existing centrifugal pump structure Shortcomings, and inconvenience is installed, so that the performance of eating liquid of impeller all has much room for improvement, the energy of eating liquid properties of centrifugal pump depends primarily on the blade of centrifugal pump, existing impeller wheel sheet all is more smooth designs with the surface of radiation camber line dividing plate, this smooth surface has reduced the frictional force with liquid, causes the ability that liquid properties reduces and then liquid is carried in impact of eating when impeller is worked.
The model utility content
The utility model is intended to for the deficiency that exists in the background technique, and a kind of high-efficient energy-saving centrifugal pump impeller that proposes.
High-efficient energy-saving centrifugal pump impeller of the present utility model, to be consisted of by upper cover plate, lower cover and more than one involute blade, its upper cover plate central authorities are provided with axle sleeve hole, coaxial heart is provided with inlet hole on the lower cover, uniform more than one involute blade between upper cover plate and the lower cover, between the far-end of upper cover plate and lower cover and two involute blades that face mutually, consist of exhaust port, the acceleration projection of evenly arranging on the outer arced surface of involute blade.
As further improvement of the utility model, the edge of close axle sleeve hole is provided with more than one attachment hole, lower cover is provided with connecting sleeve at the edge of inlet hole.
As further improvement of the utility model, described acceleration projection outer surface is the corner block of arc, and the expansion direction of arc is consistent with the bearing of trend of involute blade.
A kind of high-efficient energy-saving centrifugal pump impeller of the present utility model, all are being convex-concave designs between the impeller inside and on the surface of radiation camber line blade, strengthened blade when rotated and the frictional force between the liquid, also increased the area of contact with liquid, and then improved the working efficiency of centrifugal pump, thereby reach the purpose of efficient energy-saving.
