Abstract
The invention relates to a submerged pump and belongs to the technical field of submerged pumps. The inner wall surface of an impeller cavity and the inner wall face of a water outlet pipeline of the submerged pump are coated with drain materials, and the drain materials are formed by mixing, by weight, two parts of polytetrafluoroethylene and one part of ceramic particles and then adding 0.05 part of glass fibers. The surface of an impeller is coated with the drain materials, water cannot be attached to the surface of the impeller, energy consumption is reduced, and the service life is prolonged. Meanwhile, silicon nitride is added in the drain materials to improve hardness, and the drain materials are prevented from being abraded by gravel.
Description
Technical field
The present invention relates to a kind of submersible pump, belong to submersible pump technical field.
Background technique
When the work of submersible pump, because the surface tension of water has a small amount of water attached thereto on the inner-walls of duct of current process.The water adhering to has increased the friction of current inside, thereby has wasted energy.
Summary of the invention
The present invention wants technical solution problem to be: overcome the shortcoming of above-mentioned technology, provide a kind of impeller cavity and outlet conduit inner wall surface to be coated with the submersible pump of hydrophobic material.
In order to solve the problems of the technologies described above, the technological scheme that the present invention proposes is: a kind of underwater pump with hydrophobic, and the impeller cavity of described submersible pump and outlet conduit inner wall surface are coated with hydrophobic material; Described hydrophobic material adds the glass fibre of 0.05 part to form by two parts of teflon by weight ratio, 1 part of ceramic particle after mixing again.
Further, described hydrophobic material is also added with the silicon nitride of 0.5 part.
The hardness of stupalith is 7, and in sand, the hardness of silica sand, also in 7 left and right, in order to increase the wear resistance of hydrophobic material, is added hardness 9 to 9.5 silicon nitrides of certain component.
The present invention applies hydrophobic material at impeller cavity and outlet conduit inner wall surface, makes water in its surface attachment, not reduce energy consumption, meanwhile, is also added with silicon nitride in hydrophobic material, to increase hardness, prevents gravel wearing and tearing hydrophobic material.
Embodiment
Embodiment
The underwater pump with hydrophobic that the present embodiment provides, its impeller cavity and outlet conduit inner wall surface are coated with hydrophobic material; This hydrophobic material adds the glass fibre of 0.05 part, the silicon nitride of 0. 5 parts to form by two parts of teflon by weight ratio, 1 part of ceramic particle after mixing again.
Utilize the tetrafluoroethylene of rough surface and ceramic particle to realize hydrophobic, utilize pottery and silicon nitride to realize high hardness and wear and tear lower than gravel.
The present invention is not limited to the concrete technological scheme of above-described embodiment, and all employings are equal to replaces the technological scheme forming, and is the protection domain of requirement of the present invention.
