Electromagnetic shaftless vortex blade centripetal high-pressure water pump

Abstract

The invention belongs to the technical field of motor devices with pump and motor integration, and discloses an electromagnetic shaftless vortex blade centripetal high-pressure water pump. A motor body, a rotary cylinder, multiple continuous strip-shaped positive centripetal vortex blades, a connecting piece and a switch form the high-pressure water pump, and then a motor device with pump and motor integration is formed; an electromagnetic field stator and an electromagnetic field rotor are arranged in an electromagnetic field, and the shaftless continuous strip-shaped positive centripetal vortex blades are directly arranged in the rotor; continuous strip-shaped periodically-surrounding positive multi-vertex blade channels are formed in the rotary cylinder, the radii of the blades change in a curve from large to small, the centripetal inclination angles change topologically in order from 90 degrees to 45 degrees, the screw pitches change in order from large to small, and the blade channel spaces change in order from large to small. The high-pressure water pump overcomes the defects of a traditional water pump and has the advantages of being high in rotating suction capacity, capable of generating high pressure, saving power and working stably, low in noise, compact and reasonable in body structure and the like.

Description

technical field [0001] The invention belongs to the technical field of pump-machine integrated motor equipment, and in particular relates to an electromagnetic shaftless vortex vane centripetal high-pressure water pump. Background technique [0002] Traditional water pumps include volumetric pumps: the use of periodic changes in the volume of the working chamber to transport liquid; vane pumps: use of the centrifugal force generated by the interaction between the blade and the liquid to lift the water to a high position due to the centrifugal force generated by the high-speed rotation of the impeller.

Problems solved by technology

In particular, there are many high-rise buildings in the current city. When encountering fire rescue, the pressure of centrifugal high-pressure water pumps often cannot increase, and the application is limited.

The reason is that the structure of the centrifugal water pump is unreasonable, and there are many disadvantages in the use of low pressure, low work efficiency, high power consumption, and high noise.

[0003] To sum up, the problem existing in the existing technology is: in the case of fire rescue, the pressure of the traditional centrifugal high-pressure water pump is often unable to increase, and the application is limited

The key is that most of the traditional centrifugal water pump blades work in series with unit blades. The contact time between the blades and the water body is short, the acceleration force is small, and the resistance of the centrifugal water body at the boundary is very large. There are many disadvantages such as low water pressure, high power consumption, and high noise.
