Novel pump impeller

Abstract

The invention provides a novel pump impeller. The novel pump impeller comprises a cover plate, a front blade and a rear blade, wherein a connecting part is arranged in the middle of the cover plate; the portable pump impeller is arranged on a power output shaft of an engine through the connecting part on the cover plate; the front end face of the cover plate is provided with at least three front blades at equal angles; the rear end face of the cover plate is provided with at least three rear blades at equal angles; the cover plate, the front blade and the rear blade are integrally formed; the front blade comprises a blade front end part and a blade rear end part; the blade rear end part is bent in the counter clockwise direction; and an included angle is formed between the blade front end part and the blade rear end part. According to the novel pump impeller, the conventional impeller structure is improved, so that a draining pump can reach a high lift just by using a single impeller. Therefore, the impeller can be directly installed on the power output shaft of the engine for use without a shaft coupling, so that the structure of a centrifugal pump can be greatly simplified.

Description

technical field [0001] The invention relates to the field of centrifugal pump accessories, in particular to a novel pump impeller. [0002] Background technique [0003] Before the water pump works, the pump body and the water inlet pipe must be filled with water, and then rely on the high-speed rotating impeller to make the liquid gain energy under the action of inertial centrifugal force to increase its internal pressure. When the impeller rotates rapidly, the blades promote the water to rotate quickly , the rotating water flies away from the impeller under the action of centrifugal force. After the water in the pump is thrown out, the central part of the impeller forms a vacuum area, and then the water from the water source passes through the tube under the action of atmospheric pressure (or water pressure). The net is pressed into the water inlet pipe, so that the circulation is endless, and continuous pumping can be realized, because it has the advantages of simple str...

[0003] Before the water pump works, the pump body and the water inlet pipe must be filled with water, and then rely on the high-speed rotating impeller to make the liquid gain energy under the action of inertial centrifugal force to increase its internal pressure. When the impeller rotates rapidly, the blades promote the water to rotate quickly , the rotating water flies away from the impeller under the action of centrifugal force. After the water in the pump is thrown out, the central part of the impeller forms a vacuum area, and then the water from the water source passes through the tube under the action of atmospheric pressure (or water pressure). The net is pressed into the water inlet pipe, so that the circulation is endless, and continuous pumping can be realized, because it has the advantages of simple structure, easy operation, easy flow adjustment, and is suitable for the transportation of various special materials. In order to achieve a certain pumping effect, Currently commonly used as figure 1 The multi-stage centrifugal pump shown is for pumping water, which requires multiple impellers to rotate, so a coupling is required to connect multiple impellers, which greatly increases the complexity of the entire centrifugal pump structure and makes the centrifugal pump difficult to carry
