Abstract

The invention provides a micro centrifugal pump. The micro centrifugal pump comprises a permanent magnet DC brushless motor (1) and a pump body (2) driven by the permanent magnet DC brushless motor (1), wherein the permanent magnet DC brushless motor (1) is provided with a photoelectric control element or a Hall control element (17); a rectifier bridge is configured in the photoelectric control element or the Hall control element (17) and used for converting alternating current into direct current; a rotor (14) of the permanent magnet DC brushless motor (1) self-contains a permanent magnet material with high magnetic flux density; a stator (15) comprises a plurality of coil windings; the Hall control element (17) controls the plurality of coil windings of the stator (15) to be regularly connected with the direct current to change the current directions of the coil windings so as to form a rotating magnetic field; the rotating magnetic field attracts the rotor (14) to rotate together; and finally, an impeller (22) of the pump body (2) is driven to rotate. The whole pump efficiency of the micro centrifugal pump can be improved, and the energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of water pumps, in particular to a small and micro centrifugal water pump. Background technique [0002] A pump (Pump) is a machine that does work on a fluid and is used to increase the pressure of the liquid to make the liquid flow. In industrial production and daily life, water pumps are used to transport clear water and other liquids whose physical and chemical properties are similar to water, and are widely used, such as tap water projects, air conditioning circulating water projects, boiler water supply, pressurized water supply, fire sprinkler systems , irrigation, power station, industrial water supply system, shipbuilding industry and oil refining industry and other fields. [0003] Water pumps are divided into many categories according to their working principles, including centrifugal water pumps. Before the centrifugal water pump is started, the pump cavity and the water inlet pipe are filled wi...
