Problems solved by technology

The impeller is a rotating part. The rotating centrifugal force caused by eccentricity and the air force will cause the impeller to vibrate. The fan volute is a thin-walled container structure. The pressure pulsation formed by the interaction between the flow of gas and the wall of the volute will cause the volute to vibrate greatly And radiate noise, affect the work and rest of the station personnel, reduce the service life of the equipment, and the transmission of vibration to the installation feet of the equipment will affect the stability

Abstract

The invention discloses a low-noise ventilator which comprises a housing, wherein a base is mounted at the bottom end of the housing; a ventilation opening is formed in the base; an impeller and a motor are arranged in the housing; the impeller is mounted at the bottom end of the motor; a noise-reduction housing is mounted outside the motor; an air outlet is formed in the top end of the housing; and a filter screen is arranged at the air outlet. The low-noise ventilator has the following beneficial effects: the low-noise ventilator is simple in structure, small in size, convenient to maintain and convenient to operate and use; by adopting a double-layer housing structure, the low-noise ventilator can greatly reduce noise pollution, doesn't affect the working environment of workers and meanwhile is improved in stability; and an arranged heat dissipation layer can effectively prevent a motor overheating phenomenon and has high stability performance.

Description

technical field [0001] The invention relates to a ventilator, in particular to a low-noise ventilator. Background technique [0002] The ventilator is a kind of mechanical equipment with a large quantity and a wide range, which is widely used in energy power, petrochemical, metallurgy and other industrial fields and various military ships. The impeller is a rotating part. The rotating centrifugal force caused by eccentricity and the air force will cause the impeller to vibrate. The fan volute is a thin-walled container structure. The pressure pulsation formed by the interaction between the flow of gas and the wall of the volute will cause the volute to vibrate greatly And radiate noise, affect the work and rest of the station personnel, reduce the service life of the equipment, and the transmission of vibration to the installation feet of the equipment will affect the stability. [0003] Therefore, in order to solve the above problems, a new technical solution is provided. ...
