Problems solved by technology

It achieves the function of transporting liquid. When the liquid passes through the impeller, the pressure increases due to the rotation of the impeller. The function of the axial flow pump is to convert the kinetic energy of the fluid into pressure energy through the rotating impeller. In this process, the strength of the blade is compared. At the same time, some seriously polluted water contains a lot of corrosive substances, and the existing impeller materials are no longer fully applicable.

Abstract

The invention discloses an isolated axial flow pump blade which comprises a blade body. The isolated axial flow pump blade is characterized in that the blade body is a disc-shaped connection part, one face of a disc is of a spiral blade structure and the other face of the disc is of a cylinder axis structure. The blade body is formed in an injection molding mode and made of thermosetting resin nanocomposite. The outer face of the blade body is coated with an ultra high molecular weight polyethylene layer. The shortcomings of the prior art are overcome, the designed structure is reasonable, the blade and an impeller shaft can be detached, the number of blades is freely chosen, and the material is the nanometer polymer composite material which is resistant to corrosion and high in weather fastness. The isolated axial flow pump blade is not prone to corrosion, and capable of ensuring the good working performance, prolonging the service life and greatly reducing fees in maintaining and replacing the blade of the impeller.

Description

[0001] technical field [0002] The invention relates to the technical field of axial flow pump blades, in particular to independent axial flow pump blades. [0003] Background technique [0004] The axial flow pump is composed of the main parts such as the pump casing, the impeller and the shaft. The new liquid is sucked from the other end, and the liquid generates a continuous flow along the direction parallel to the rotating shaft. It achieves the function of transporting liquid. When the liquid passes through the impeller, the pressure increases due to the rotation of the impeller. The function of the axial flow pump is to convert the kinetic energy of the fluid into pressure energy through the rotating impeller. In this process, the strength of the blade is compared. At the same time, some seriously polluted water contains more corrosive substances, and the existing impeller materials cannot be fully applied. [0005] Contents of the invention [0006] The purpose...
