Impeller pump

Abstract

The invention discloses an impeller pump which comprises a pump shaft, a flow guide seat shell, a plurality of impellers driven by the pump shaft to rotate and a flow guide body connected with the flow guide seat shell; the impellers and the flow guide body are arranged on the periphery of the pump shaft in a sleeving mode; and each impeller comprises an impeller body and an impeller seat matched with the impeller body to form a liquid circulation cavity, the impeller body is provided with an installation face, a plurality of blades are installed on the installation face and located in the circulation cavity, and the installation face is a conical face inclining towards a liquid outlet of the pump. The installation faces in the impeller pump are the conical faces inclined towards the liquid outlet of the pump, liquid flows out along the conical faces under the action of centrifugal force, the centrifugal force acting on the liquid has component force towards the liquid outlet and has a pushing effect on the liquid towards the liquid outlet, the kinetic energy of the liquid can be increased, the liquid flows to the liquid outlet more quickly and enters the flow guide body, and therefore, the efficiency and the lift of the pump are improved.

Description

technical field [0001] The present invention relates to the technical field of pumping equipment, and more specifically, relates to an impeller pump. Background technique [0002] The pump is a kind of mechanical equipment used to transport fluid or pressurize the fluid. The impeller pump is a kind of pump. When it works, the impeller drives the liquid to rotate at a high speed, and transmits mechanical energy to the liquid, so as to achieve the purpose of transporting the liquid. [0003] In the process of using the existing impeller pump, the motor drives the impeller to rotate, the liquid enters from the liquid inlet, and flows out through the liquid outlet after rotating under the drive of the impeller. After the liquid enters from the liquid inlet, the impeller rotates During the process, part of the liquid cannot flow out of the liquid outlet according to the preset path, or the resistance encountered in the process of flowing from the liquid inlet to the liquid outlet...

AI Technical Summary

Problems solved by technology

[0003] In the process of using the existing impeller pump, the motor generally drives the impeller to rotate, the liquid enters from the liquid inlet, and flows out through the liquid outlet after rotating under the drive of the impeller. After the liquid enters from the liquid inlet, the impeller rotates During the process, part of the liquid cannot flow out of the liquid outlet according to the preset path, or the resistance encountered in the process of flowing from the liquid inlet to the liquid outlet is relatively large, resulting in a decrease in the efficiency and head of the pump.
