Embodiment

[0009] In the hydrophobic impeller submersible pump provided in this embodiment, the surface of the impeller is coated with a hydrophobic material; the hydrophobic material is mixed by weight of two parts of polytetrafluoroethylene and 1 part of ceramic particles, and then added 0.05 parts of glass fiber, 0.5 parts of silicon nitride composition.

[0010] Use tetrafluoroethylene and ceramic particles on the rough surface to achieve water repellency, and use ceramic and silicon nitride to achieve high hardness lower than grit wear.

Abstract

The invention relates to a submersible pump and belongs to the technical field of submersible pumps. The surface of an impeller of the submersible pump is coated with a hydrophobic material; the hydrophobic material is prepared by mixing of two parts of polytetrafluoroethylene by weight and 1 part of ceramic particles by weight and then addition of 0.005 part of glass fibers by weight. According to the submersible pump, the surface of the impeller is coated with the hydrophobic material, so that water cannot be attached to the surface of the impeller, energy consumption is reduced, and the service life is prolonged; meanwhile, silicon nitride is also added in the hydrophobic material, so that the hardness is increased, and the hydrophobic material is prevented from being abraded by gravel.

Description

technical field [0001] The invention relates to a submersible pump and belongs to the technical field of submersible pumps. Background technique [0002] When the submersible pump is working, a small amount of water will adhere to the impeller due to the surface tension of the water. The attached water will move with the impeller, and the water will move relative to other normal flowing water, and then the normal flowing water will generate additional pressure on the impeller, which will increase the energy consumption of the impeller and accelerate the wear of the impeller. Contents of the invention [0003] The technical problem to be solved by the present invention is: to overcome the disadvantages of the above-mentioned technologies, and provide a submersible pump whose surface of the impeller is coated with a hydrophobic material. [0004] In order to solve the above technical problems, the technical solution proposed by the present invention is: a hydrophobic impell...
