Description
Technical Field
The utility model belongs to a fluid supercharging machine, in particular to an amphibious self-priming pump.
Background
A pump is a machine that delivers or pressurizes a fluid. It transfers the mechanical energy of the prime mover or other external energy to the liquid, causing the liquid energy to increase. The pump is mainly used for conveying liquid such as water, oil, acid-base liquid, emulsion, suspension emulsion and liquid metal, and can also be used for conveying liquid, gas mixture and liquid containing suspended solid. Pumps can be generally classified by their operating principle into three types, positive displacement pumps, dynamic pumps and other types of pumps. In addition to classification by theory of operation, classification and naming may be by other methods. For example, the driving method may be classified into an electric pump, a turbine pump, and the like; can be divided into a single-stage pump and a multi-stage pump according to the structure; can be divided into a boiler feed pump, a metering pump and the like according to the application; the liquid can be divided into a water pump, an oil pump, a slurry pump and the like according to the property of the transported liquid. According to the structure with or without shaft, the linear pump and the traditional pump can be divided. 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, 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.
The existing pump has unscientific body structure and is easy to damage, in particular to self-sucking pumps.
