Abstract

The invention belongs to the technical field of fans, and particularly relates to an axial flow fan and a control method thereof.The axial flow fan comprises a machine shell, the machine shell comprises a first-stage machine shell body and a second-stage machine shell body which communicate with each other, a first motor is fixedly arranged in the first-stage machine shell body, and a second motor is fixedly arranged in the second-stage machine shell body; the first motor is a double-output-shaft motor, a first blade and a second blade are arranged on double output shafts of the first motor respectively, and a third blade is arranged on an output shaft of the second motor. The control method of the axial flow fan comprises the step of selecting to correspondingly start the first motor or start the first motor or start the first motor and the second motor at the same time according to the air supply distance required by design. According to the fan device, the two motors and the three blades are arranged, the problem that the conveying distance is three times that of a single-stage fan is solved, meanwhile, the size of a three-stage combined fan is reduced, and energy consumption is reduced.

Description

technical field [0001] The invention belongs to the technical field of fans, and in particular relates to an axial flow fan and a control method thereof. Background technique [0002] At present, fans are general-purpose machinery widely used in various industries of the national economy. Fans are divided into two categories: centrifugal fans and axial fans. Axial flow fans have the characteristics of large flow, small volume, and low pressure head. They are mainly used in various ventilation systems that require large flow. In the application process of current axial flow fans, in order to increase the pressure, they are used for long conveying distance or The ventilation system with large system resistance often adopts the form of multi-stage combination, and the usual practice is to design it as a series structure or a counterrotating structure. Long conveying distances require multi-fan combination. Due to the large size, the application is inconvenient, and the multi-...
