Method for denoising axial flow fan

Abstract

The invention provides a method for denoising an axial flow fan. According to the method, a silencing bottom cover, a stator, a rotor and M-shaped brackets comprising rubber damping rods are included; the silencing bottom cover comprises a first silencing pipe, a second silencing pipe, a silencing chamber and a sounding pipe; one end of the first silencing pipe and one end of the second silencing pipe are connected with the upper end and the lower end of the silencing chamber respectively, the other end of the first silencing pipe and the other end of the second silencing pipe are connected with the right outer wall of the silencing bottom cover, and the left side of the silencing bottom cover is connected with the left outer wall of the silencing chamber through the sounding pipe; the rotor is arranged in the stator, the outer wall of the stator is provided with the M-shaped brackets, and one sides of the M-shaped brackets are fixedly connected with the outer wall of the stator. The method for denoising the axial flow fan has the beneficial effects that the M-shaped brackets are arranged on the outer wall of the stator and can be fixed to the inner wall of a machine case to decrease collisions, and the purposes of reducing vibration and noise are achieved; by arranging the silencing bottom cover, sound waves can enter the silencing chamber from the first silencing pipe and the second silencing pipe; accordingly, when the sound waves enter the silencing chamber, wave crests and wave troughs are balanced, and the silencing purpose is achieved.

Description

technical field [0001] The invention relates to the field of motor equipment, in particular to a motor capable of reducing noise and vibration. Background technique [0002] In the prior art, the axial fan is usually arranged at a fixed position for air circulation. Due to its own characteristics of rotating equipment, when the plane is unstable and the rotor of the motor is not located in the center of the axis, the device will vibrate when it deviates slightly, which will easily cause the equipment to shake and become unstable. Second, it will increase the noise. Large, affecting the normal work and rest of the workers next to them. Contents of the invention [0003] The purpose of the present invention is to provide a noise reduction method for an axial flow fan with simple structure and simple operation, which is especially suitable for use in environments with high requirements for noise control. [0004] Technical scheme of the present invention is: [0005] A noi...
