Description

Integral type water pump structure
Technical Field
The utility model relates to an integral type water pump technical field specifically is an integral type water pump structure.
Background
Water pumps are machines that deliver or pressurize a liquid. It transfers the mechanical energy of prime mover or other external energy to liquid to increase the energy of liquid, and is mainly used to transfer liquid including water, oil, acid-base liquid, emulsion, suspoemulsion and liquid metal. Liquids, gas mixtures, and liquids containing suspended solids may also be transported. The technical parameters of the water pump performance include flow, suction lift, shaft power, water power, efficiency and the like; the pump can be divided into a volume water pump, a vane pump and the like according to different working principles. The displacement pump transfers energy by utilizing the change of the volume of a working chamber; vane pumps transfer energy by the interaction of rotating vanes with water and are available in the types of centrifugal pumps, axial flow pumps, mixed flow pumps, and the like. During the operation of the water pump, the water flowing in the pump is influenced by the friction between the water and the surfaces of the flow passage and the pump impeller and the viscosity of the water body, and the energy consumed by the pump is mainly used for resisting the flow friction force and the vortex resistance of the water surface. The energy consumed by the water during the flow (head loss) is used to overcome internal friction and the friction of the water with the equipment interface. If the surface of the pump and impeller is smooth (such a surface is called a hydraulic smooth surface), the surface resistance is small. The consumed energy is small, the high polymer composite material is sprayed on the overflowing surface and the impeller of the water pump, so that the surface of the overflowing surface and the impeller of the water pump form a hydraulic smooth surface, the surface smoothness of the super-smooth surface coating is 20 times of that of polished stainless steel, and the extremely-smooth surface reduces the layering of fluid in the pump, so that the internal turbulence of the pump is reduced, the volume loss and the hydraulic loss in the pump are reduced, and the power consumption is reduced. The purpose of reducing the water flow resistance loss is achieved, so that the hydraulic efficiency of the water pump is improved, and meanwhile, the mechanical efficiency and the volumetric efficiency can also be improved to a certain extent. The compactness of the molecular structure of the coating can isolate the contact of media such as air, water and the like and the parent metal of the water pump impeller, and reduce electrochemical corrosion and rust to the maximum extent. In addition, the polymer composite material is a high molecular polymer, has chemical corrosion resistance, can improve the corrosion resistance of the pump, and can greatly enhance the erosion resistance and corrosion resistance of the pump.
At present, the common water pump structure has the problems of poor sealing effect and complex installation and operation, thereby causing great inconvenience for users.
