Diesel generator set installed silencer action principle?

Noise has always been a boring and a headache for us and there are noise problems in the diesel generator set equipment, but we use the diesel generator set. To solve these noise problems, silencers were born.

A diesel generator set muffler introduction

A muffler is a device used to reduce noise in the air flow channel or in the intake and exhaust system of a diesel generator set. The muffler is a useful equipment in the control generator de-noising engineering, which can block the transmission of sound waves and allow the airflow to pass through.

Second, product structure

There are many kinds of diesel generator muffler, which can be divided into resistance muffler, resistance muffler, impedance composite muffler, micro perforated plate muffler, small hole muffler, active muffler, damping muffler seven categories.

Three, operating principle

Diesel generator muffler mainly adopts porous sound absorbing material to reduce noise. The sound absorbing material is fixed on the inner wall of the air flow channel and arranged in the pipeline in a certain way to form a resistive muffler. When sound waves enter the resistive muffler, some noise will friction in the pores of the porous material and be converted to * dissipation, thus weakening the sound waves through the muffler. Resistive mufflers are like pure resistive circuits in electricity, and sound absorbing materials are similar to resistors. Therefore, people call this kind of muffler resistive muffler. The resistive muffler has good effect on middle and high frequency, but poor effect on low frequency.

Four, diesel generator set silencer to adapt to the scale

The diesel generator muffler is the generator airflow channel (smoke pipe) noise reduction equipment, is the generator noise reduction engineering is indispensable equipment.
