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
Technical field
The present invention relates to axial flow pump blade inner technical field, specifically belong to free-standing axial flow pump blade inner.
Background technique
Axial-flow pump has the critical parts such as pump case, impeller and rotating shaft to form, on impeller, there is the blade of propeller-like as dry, in the time that impeller is made High Rotation Speed by power engine driving together along with rotating shaft, each blade is pushed liquid to one end, draw new liquid from the other end again, be that liquid produces along the direction continuous-flow paralleling with rotating shaft simultaneously.Reach the effect of carrying liquid, when liquid passes through impeller, due to the effect of wheel rotation, pressure improves, the effect of axial-flow pump is to make the impeller of the kinetic energy of fluid over-rotation be converted into pressure energy, in this process, the intensity of blade is had to higher requirement, contain corrosive material many in the more serious water quality of some damage ratios, existing impeller material can not be completely applicable simultaneously.
Summary of the invention
The object of this invention is to provide free-standing axial flow pump blade inner, the deficiencies in the prior art are overcome, project organization is reasonable, blade body is a disc attachment portion, disk one side is helical blade structure, another side is cylinder axis structure, described blade body adopts injection moulding to make, material is thermosetting resin nano composite material, blade body outside is coated with ultra-high molecular weight polyethylene coating, can on impeller shaft, select impeller quantity is installed, there is the advantages such as convenient to use, the life-span long, corrosion-resistant, weatherability is strong, maintenance cost is low simultaneously.
