Coaxial permanent magnet power generation water pump

Abstract

The invention discloses a coaxial permanent magnet power generation water pump. The water pump comprises a shell, an internal combustion engine installed in the shell, a power generator and the waterpump connected with the power generator. The generator is a permanent magnet generator; a rotating shaft of the permanent magnet generator is coaxial with an output shaft of the internal combustion engine; turbine fan blades are arranged in the water pump, and a water inlet pipe and a water outlet pipe are mounted on an outer side surface of the water pump; a rotating shaft of the permanent magnetgenerator is in driving connection with the turbine fan blades; telescopic frames and universal wheels are arranged on a periphery of a bottom of the shell in parallel; each telescopic frame comprises a supporting block, a screw and a support; the supporting block is provided with a threaded hole, and the threaded hole is internally in threaded connection with the screw; and a lower end of the screw is fixedly connected with the support. The coaxial permanent magnet power generation water pump is compact in structure, coaxially arranged and concise and reliable in overall structure; and meanwhile, the permanent magnet generator is adopted, materials are saved, weight is light, a size is small, and power generation and drainage quality is high. In addition, the telescopic frames are arranged so that the power generation water pump can normally work in an environment of a non-flat table.

Description

technical field [0001] The invention relates to the field of permanent magnet generators and water pumps, in particular to a coaxial permanent magnet generator water pump. Background technique [0002] The centrifugal pump is composed of a water pump and a bracket. It is low in cost, light in weight, and easy to maintain. It also has the advantages of low manufacturing cost and low noise. The working principle of the centrifugal pump is that when the pump is filled with water, the engine drives the impeller to rotate. As a result, centrifugal force is generated, and the water in the impeller channel is thrown to the periphery and flows into the pump casing under the action of centrifugal force, so the pressure in the center of the impeller decreases, which is lower than the pressure in the water inlet pipe, and the water flows in from the suction pool under the action of this pressure difference. The impeller, so that the water pump can continuously absorb water and supply w...

Problems solved by technology

[0003] Most of the existing fuel engine water pumps are used for field irrigation. The generator shaft is relatively long, and the cooling fan is located at the front end. The overall size is very long, which is not conducive to heat dissipation and is inconvenient to move; It is easy to cause equipment damage, and at the same time increase the cost of maintenance, causing inconvenience to users
