Introduction to Structure and Principle of Roots Blower Outlet Silencer

The structure and principle of Roots blower outlet silencer are introduced. Roots blower is a kind of mechanical equipment widely used in various industrial fields. Its outlet silencer plays an important role in reducing the noise of the fan during operation. Xinqianshun Machinery will introduce the structure and principle of Roots blower outlet silencer in detail:

1、 Structure of silencer

The outlet silencer of Roots blower is mainly composed of silencing shell, sound absorption material, sound insulation material, elastic support and air flow channel. Among them, the silencer shell is the shell of the whole silencer, which is usually welded from steel plates, with good structural strength and sealing performance. Sound absorption materials and sound insulation materials are the key components inside the silencer, which are used to absorb and isolate the noise when the fan is running. The elastic support is used to alleviate the vibration and impact of the muffler during operation, and ensure the stable operation of the muffler. The airflow channel is to guide the gas to pass through the outlet of the blower smoothly, reduce the sudden change and vortex of the airflow, and thus reduce the noise.

2、 Principle of silencer

The main principle of Roots blower outlet silencer is to absorb and isolate the noise during fan operation through sound absorption materials and sound insulation materials. Sound absorbing materials are porous and can absorb sound waves and reduce noise decibels. Sound insulation materials have high density and thickness, which can convert sound waves into heat energy, thus reducing the spread of noise. The elastic support can alleviate the vibration and impact of the muffler during operation, and ensure the stable operation of the muffler. The design of air flow channel can reduce the sudden change and vortex of air flow, thus reducing the noise.

In a word, the structural principle of Roots blower outlet silencer is to reduce noise through reasonable structural design, selection of high-quality sound absorption materials and sound insulation materials, and appropriate elastic support.
