Noise Reduction Solutions for Diesel Generators

A generator set will produce a noise level of 105 decibels at a distance of one meter when it operates at a speed of 1500 rpm. To prevent noise from spreading out of the machine room, the noise reduction project should include the following aspects: 1. Sound absorption and insulation treatment for the initial entrance of the machine room; 2. Design of noise reduction air ducts for the air intake and exhaust system as well as the exhaust gas emission system; 3. Insulation wrapping of the exhaust pipes.

The silent generator set achieves noise reduction by lowering the noise level below the normal operating decibels. As the main component for noise reduction of open-frame diesel generator sets, the muffler plays a crucial role. Dingbo Diesel Generator Manufacturer, a professional generator manufacturer, will introduce the muffler used in the noise reduction project of diesel generator sets and its performance requirements.

The exhaust noise of diesel generator engines is extremely high. To meet environmental protection requirements, noise reduction measures are necessary. Installing a muffler in the exhaust pipeline can minimize noise to the greatest extent. Using a muffler to handle exhaust noise is the most effective method. Therefore, the muffler is an essential accessory for diesel generator sets. It can not only reduce the heat emitted by the unit into the machine room but also reduce the operating vibration of the unit, thereby achieving the purpose of noise attenuation.

A muffler is a device that allows airflow to pass through while controlling the noise generated by the airflow. It is the primary means of reducing aerodynamic noise. There are various types of mufflers. According to the noise reduction principle and function, they can be divided into three main categories: resistive, reactive, and impedance composite mufflers, as well as micro-perforated plate mufflers. For high-intensity noise generated by the discharge of high-temperature, high-pressure, and high-speed airflow, there are other types of mufflers such as throttling decompression, small-hole injection, and porous diffusion mufflers.

The performance requirements for the muffler used in the noise reduction project of diesel generator sets mainly include the following items:

1.Acoustic performance: It is required to have a sufficiently large noise reduction capacity that meets the requirements within a wide frequency range.

2.Aerodynamic performance: It is required to have low resistance to airflow and low regenerated noise caused by airflow.

3.Structural performance: It should have a reasonable spatial layout, simple structure, easy assembly and disassembly, and be sturdy and durable.

4.Appearance and decoration requirements: It should be beautiful and elegant, coordinate with the overall equipment, and reflect the characteristics of environmental protection.

5.Cost-performance requirement: It should offer a good balance between performance and price.
