The invention relates to the field of unmanned aerial vehicles, in particular to a brushless high-pressure high-speed centrifugal pump for a multi-rotor unmanned aerial vehicle and the unmanned aerialvehicle. The brushless high-pressure high-speed centrifugal pump comprises a connecting assembly connected with the unmanned aerial vehicle, and is characterized by further comprising a brushless motor assembly fixedly connected with the connecting assembly, an output shaft of the brushless motor assembly is connected with a centrifugal assembly, the centrifugal assembly comprises a first-stage centrifugal disc connected with the output shaft, first-stage dispersing blades are uniformly distributed on the upper surface of the first-stage centrifugal disc, and liquid flow channels are formed among the first-stage dispersing blades; and a second-stage centrifugal disc connected with the first-stage centrifugal disc is further included, and multiple second-stage dispersing blades are arranged on the lower surface of the second-stage centrifugal disc. According to the brushless high-pressure high-speed centrifugal pump, the spraying radius capable of being covered by the centrifugal pumpis increased while the atomization effect is guaranteed, the sand blasting efficiency is improved, the number of times of reciprocating spraying of the unmanned aerial vehicle is reduced, and the operation efficiency and efficiency of the unmanned aerial vehicle are greatly improved.

    本发明涉及无人机领域,尤其涉及一种多旋翼无人机用的无刷高压高速离心泵和无人机;无刷高压高速离心泵,其包括与无人机连接的连接组件,其特征在于:还包括与连接组件固定连接的无刷电机组件,无刷电机组件的输出轴连接有离心组件,所述离心组件包括与输出轴连接的一级离心盘,一级离心盘的上表面均布设有一级分散叶片,一级分散叶片之间形成液体流道;还包括与一级离心盘连接的二级离心盘,二级离心盘的下表面设有若干个二级分散叶片;本发明设计了一种无刷高压高速离心泵,保证雾化效果的同时增大了离心泵所能覆盖的喷洒半径,提高了喷砂的效率,减少了无人机往复喷洒的次数,使得无人机的作业效率和效能大大的提升。
