Abstract

The invention belongs to the technical field of fans, and particularly relates to an axial flow fan made of fiberglass-reinforced plastic. The axial flow fan made of the fiberglass-reinforced plasticcomprises a controller, an air duct and an impeller installed on a motor output shaft; the air duct is composed of a first air duct body and a second air duct body, the first air duct body and the second air duct body are connected through a damping unit, the input end of a motor is connected with a second hollow cylinder through a double-shaft telescopic rod, and the two ends of the double-shafttelescopic rod are fixedly connected with the inner wall of the second hollow cylinder and the motor separately; and a conical cylinder is fixedly connected to the end, far away from the impeller, ofthe output end of the motor. According to the axial flow fan made of the fiberglass-reinforced plastic, the structure is simple, and noise and dust are reduced while the ventilation efficiency of thefan is improved.

Description

technical field [0001] The invention belongs to the technical field of ventilators, in particular to a fiberglass axial flow fan. Background technique [0002] FRP axial flow fan refers to the fan made of glass fiber reinforced plastic (FRP). Its appearance and size are exactly the same as steel axial flow fans, except that the shell and impeller are made of FRP. Its biggest feature is corrosion resistance, acid and alkali resistance, and belongs to A kind of anti-corrosion fan. [0003] FRP axial flow fan itself is a noise source due to its own motor and other reasons. FRP axial flow fan will generate strong airflow when it works, and the resulting vibration will affect the surrounding area without proper isolation. Buildings will also produce strong noise pollution and dust pollution, and the FRP axial flow fan will produce a certain degree of mechanical vibration during work, which will accelerate the wear of the fan bearing and reduce the service life of the fan; when t...
