Professional Roots fan acoustic enclosure-Non-standard customization manufacturers

Fan noise analysis:

    The noise of the fan is divided into electromagnetic noise, mechanical noise and aerodynamic noise. Of these three types of noise, the aerodynamic noise has the highest intensity, wide frequency band and large impact. And aerodynamic noise is a major reason for the impact of fan noise decibels. According to the noise spectrum, the noise is divided into vortex noise and rotating noise. Vortex noise is mainly due to the boundary layer separating from the airflow, resulting in pressure pulsations on the blades and radiating an unstable flow noise.

Allway Fan Sound Insulation Enclosure Production Features:

    1. The fan acoustic insulation is made up of acoustic insulation components and supporting structures. Depending on the construction requirements of the environment, the walls of the acoustic insulation can be made of 1.5-2mm galvanised steel or aluminium plates to enhance the impact resistance of the hood. The surface is treated with electrophoresis and electrostatic spraying on both sides to ensure that the acoustic enclosure will not rust for more than ten years.

    2、The fan acoustic enclosure adopts a modular design scheme, which makes it easy to transport to different sites and is suitable for on-site installation and easy to maintain and repair.

    3、According to different site use requirements, sound insulation doors, sound insulation windows, lighting equipment and ventilation and heat exchange systems can be installed in the fan noise enclosure, and according to the actual use requirements. In order to ensure the ventilation and heat dissipation of the equipment, holes need to be opened in the Roots fan sound insulation enclosure, and in order not to affect the effect of noise treatment, mufflers are installed on the holes; in order to facilitate the inspection and maintenance of the equipment, sound insulation doors and windows are added to the sound insulation room, and in order to prevent sound leakage, the joints of doors, windows and covers are filled with soft rubber and other materials; mufflers are installed on the inlet and outlet pipes of the Roots fan to reduce the aerodynamic noise of the import and export. Customised fan enclosures of different sizes Custom-made fan enclosures of different sizes and painted in various colours to enhance recognition.

    Normally, the size of the enclosure needs to be configured according to the size of the motor model, and the specific size of the enclosure needs to be customised according to the approximate size of the Roots fan. For detailed parameters of each model, please contact us。
