The outlet muffler of Roots blower is an important equipment used to reduce the intake and exhaust noise of Roots blower. The following is a detailed introduction to it:
1、 Function
The outlet muffler of Roots blower is mainly used to reduce aerodynamic noise such as the inlet and outlet of Roots blower, ensuring that the noise generated by the blower during operation does not pollute the environment and protect the hearing health of workers.
2、 Principle
The outlet muffler of Roots blower is developed based on the principle of sound blocking plate for noise reduction. It adopts a resistive structure for silencing high and medium frequency noise, as well as an anti type structure for silencing medium and low frequency noise. At the same time, high-frequency and low-frequency noise reduction zones are set up in the resistive channel to maximize the width of the noise reduction frequency band and achieve good noise reduction effect.
3、 Structure
The structure of the outlet muffler of a Roots blower is usually composed of many parallel unit muffler tubes arranged, with porous sound-absorbing materials filled between the muffler tubes. To reduce the radiation sound caused by the vibration of the shell wall excited by the airflow, reinforcement ribs are installed on the outer shell. In addition, according to the different inlet and outlet structures of the fan, the muffler is also divided into circular and rectangular structures.
4、 Characteristics
1. Excellent acoustic performance: It can effectively reduce the aerodynamic noise generated by Roots blowers.
2. Good aerodynamic performance: It has little impact on the airflow of the fan and will not significantly reduce the performance of the fan.
3. Reasonable structure: easy to install and maintain, able to adapt to the needs of different fan models and installation environments.
4. Significant noise reduction effect: The noise reduction effect is usually between 30-40dB (A), which can meet the noise reduction requirements of most industrial environments.
5、 Application
Roots blower outlet silencers are widely used in industries such as petrochemicals, building materials, electricity, smelting, fertilizers, as well as in aquaculture oxygenation, sewage treatment aeration, cement transportation, and other fields. In these fields, Roots blowers, as important gas conveying and pressurization equipment, have always been concerned about their noise issues. By installing an outlet muffler, the noise of the fan can be effectively reduced, the working environment can be improved, and the work efficiency and quality of life of employees can be enhanced.
6、 Selection and Installation
1. Selection: When selecting a Roots blower outlet muffler, it is necessary to provide information such as the fan model, usage scenario, air volume and speed, and nozzle size, so that the manufacturer can customize production according to actual needs.
2. Installation: During installation, ensure that the muffler is tightly and reliably connected to the inlet and outlet of the fan to avoid air leakage. At the same time, attention should be paid to the installation direction of the muffler to ensure that it can effectively reduce noise.
In summary, the outlet muffler of Roots blower plays an important role in reducing fan noise, protecting the environment and employee health. When selecting and installing, actual needs and environmental conditions should be fully considered to ensure the effective noise reduction effect.
