Abstract:
An impeller pump, a spraying system and an unmanned aerial vehicle. The impeller pump comprises a pump body, a motor (210), and an isolation member (311); the pump body, the motor (210) and the isolation member (311) are detachably mounted together so as to form an impeller pump; the pump body comprises a pump housing (111) and an impeller; the impeller comprises an impeller main body (121) and a first magnetic member (123); the motor (210) comprises a motor shaft (211) and a second magnetic member (221) fixed to the motor shaft (211); and the motor shaft (211) drives the second magnetic member (221) to rotate when rotating, so as to drive the first magnetic member (123) to drive the impeller main body (121) to rotate. The pump body, the motor and the isolation member are detachably mounted, so that parts of the impeller pump are modularized. Magnetic transmission is provided for the impeller pump by means of two magnetic members, and a liquid cavity of the impeller pump is isolated from an inner cavity of the motor by providing the isolation member.
