Abstract

The invention discloses a multi-stage differential water pump capable of reducing noises. The multi-stage differential water pump comprises an outer shell, a driving stator assembly and a rotor assembly; the driving stator assembly and the rotor assembly are installed on the outer shell; the driving stator assembly comprises at least two driving stators which are distributed along the axial direction of the outer shell; the rotor assembly comprises a multi-stage impeller module; each stage of impeller module in the multi-stage impeller module comprises a rotor and an impeller assembly installed on the rotor; and each driving stator provides rotating driving force for the rotor of the corresponding stage of impeller module. Different voltages are set for different driving stators to controlthe rotating speed of the corresponding rotors, and differential rotation of the multi-stage impeller module is achieved. According to the differential water pump, multi-stage pressurization transmission is realized, the fluid resistance is reduced, the lift of the pump is improved, and the noises caused by fluid pressure transformation due to changes the rotating speed among the multi-stage impellers is remarkably reduced.

Description

technical field [0001] The invention belongs to the technical field of water pumps, in particular to a magnetic levitation multi-stage differential shaftless water pump, which can be widely used in water transportation, and can be used in water conservancy industry, hydropower industry, sewage treatment industry and the like. Background technique [0002] A pump is a machine that transports or pressurizes a liquid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali, emulsion, suspoemulsion and liquid metal. It is the most common in modern industrial production. A kind of industrial equipment, it plays an important role in almost all fields of modern industry. [0003] Water pumps are divided into positive displacement pumps and vane pumps. Vane pumps include centrifugal pumps, axial flow pumps, mixed flow pumps, etc., ...
