Low noise Roots blower
Low noise Roots blower is a special type of Roots blower characterized by relatively low noise generated during operation. The following is a detailed introduction to low-noise Roots blowers:
1、 Definition and Working Principle
Low noise Roots blower belongs to the positive displacement fan, which sucks in and exhausts gas by rotating two rotors in the gas chamber. During this process, mechanical vibration and turbulent airflow generate noise, but low-noise Roots blowers effectively reduce these noises through special design and manufacturing processes.
2、 Structure and Characteristics
1. Structure:
① Low noise Roots blowers are usually composed of a casing, wall panels, impellers, bearing boxes, sealing devices, and transmission devices.
② The impeller usually adopts a three bladed design, which has less gas pulsation and vibration compared to a two bladed design, resulting in lower noise.
2. Characteristics:
① Low noise: By optimizing design and manufacturing processes, the noise generated during operation has been effectively reduced.
② Smooth operation: Simple structure, smooth operation, and stable performance.
③ Strong adaptability: suitable for various purposes, such as aquaculture oxygenation, sewage treatment aeration, pneumatic conveying, etc.
3、 Noise reduction measures
To further reduce the noise of low-noise Roots blowers, the following measures can be taken:
1. Spring shock absorber: Using spring shock absorbers can effectively absorb and attenuate mechanical vibrations, thereby reducing the propagation of noise.
2. Soundproof cover: Installing a soundproof cover outside the fan can isolate the propagation path of noise and further reduce noise.
3. Optimize airflow design: By optimizing airflow design, reduce airflow turbulence and eddies, thereby reducing noise generation.
4、 Application Fields
Low noise Roots blowers are widely used in the following fields:
1. Aquaculture: Used for oxygenation and aeration in aquaculture facilities such as fish ponds and shrimp ponds.
2. Wastewater treatment: Used for processes such as aeration, agitation, and transportation in wastewater treatment plants.
3. Pneumatic conveying: used for conveying powder and granular materials.
4. Other fields: gas delivery and pressurization systems in industries such as chemical, food, and pharmaceutical.
5、 Selection and Precautions
When choosing a low-noise Roots blower, the following points should be noted:
1. Understand requirements: Clarify your usage needs and work environment, and choose suitable models and specifications.
2. View certification: Select products that have undergone relevant certification to ensure that production and performance meet requirements.
3. Understand after-sales service: Choose manufacturers or distributors with good after-sales service to receive timely technical support and maintenance services during use.
In summary, low-noise Roots blowers have the characteristics of low noise, smooth operation, and strong adaptability, and are widely used in aquaculture, sewage treatment, pneumatic conveying, and other fields. When making a purchase, it is necessary to understand one's own needs and check the certification and after-sales service of the product.
