Efficient axial flow pump

Abstract

The invention discloses an efficient axial flow pump. The efficient axial flow pump comprises a base and a shell, the upper end of the base is fixedly connected with two supporting plates, the two supporting plates are oppositely arranged, the upper ends of the two supporting plates are fixedly connected with the shell, one end of the shell is fixedly connected with a pump room, and the side wallof the pump room is provided with a water inlet pipe and a water outlet pipe in a communicating mode; A cooling device connected with the water inlet pipe is arranged on the inner wall of the shell, amotor is fixedly connected to the inner bottom wall of the shell, the motor penetrates through the shell and extends outwards, the extending end of the motor is connected with the pump room, a barrelis in contact connection with the side wall of the motor and fixedly connected to the inner bottom wall of the shell, and a heat dissipation device is arranged on the bottom wall, away from the motor, of the shell; and a backflow mechanism for draining water is arranged at the lower end of the shell. The effect that a small part of water is pumped out of the water inlet pipe through an intercepting pipe and enters a guide pipe is achieved, the inside of the shell can be better cooled through an atomizing nozzle, and therefore equipment damage caused by too high temperature is avoided.

Description

Technical field [0001] The present invention relates to the field of liquid pumps, and more particularly to a high-efficiency axial flow pump. Background technique [0002] The axial flow pump is one of the blade pump. It transports the liquid in the radial direction as the centrifugal pump, but flows in the pump axial direction, which is called the axial flow pump, and because its blade is spiral, it is like aircraft and the propellers on the ship, so Also known as the propeller pump, the axial flow pump can be divided into vertical, oblique and horizontal. There is only a different form of pump between them, and the internal structure is basically the same. [0003] One axial flow pump used on the ground is in order to protect the drive motor, and in order to prevent people from being misady to drive the motor, the drive motor is installed in the motor protective case, and when the long run will lead to overheating the motor. If it is not timely heat dissipation, it may cause a...

AI Technical Summary

Problems solved by technology

[0003] Among them, a kind of axial flow pump used on the ground is to protect the drive motor, and also to prevent people from accidentally touching the drive motor and causing injury. Failure to dissipate heat in time may cause motor failure, thereby reducing pumping efficiency
