Introduction to noise control methods of Roots blower

Roots blower is a common industrial fan, which is widely used in the fields of air transmission, ventilation, waste gas treatment, etc. However, due to the noise generated by its high-speed rotation and airflow impact, noise pollution control has become an important issue to be considered when using Roots blower. The following are several solutions for noise control of Roots blower.

1、 Design Selection

Reasonable selection and design: When selecting Roots blower, low-noise model and specification can be given priority. Some manufacturers provide noise test data that can be used to compare the noise levels of different models of fans. In addition, some specially designed Roots blowers, such as those with double-layer shells or noise damping materials, can reduce noise generation.

Control of fan operating parameters: adjusting the operating parameters of Roots blower, such as fan speed, inlet and outlet airflow speed, can affect the generation and transmission of noise. By reasonably adjusting these parameters, the noise level of Roots blower can be reduced.

2、 Sound insulation and noise reduction

Installation of sound insulation cover: the sound insulation cover is an effective noise reduction measure, which can establish a layer of physical barrier around Roots blower to isolate the transmission of noise. The sound insulation cover usually adopts sound absorbing materials and multi-layer structure to absorb and reduce the transmission of noise. When designing the acoustic enclosure, it is necessary to consider the needs of ventilation and heat dissipation, and ensure the normal operation of the Paultz fan.

Vibration and structural damping: the vibration and structural conduction of Roots blower will also produce noise. By using damping materials, shock absorbers or suspension devices and other damping measures, the vibration and structure conduction of the fan can be reduced, thus reducing the noise level.

Noise absorption treatment: sound absorption materials, such as sound absorption foam and cotton, are used on the inlet and outlet of Roots blower and pipes to effectively absorb noise energy and reduce noise transmission and reflection.

3、 Maintenance inspection

Regular maintenance and inspection: regularly maintain and inspect roots blower to ensure that the equipment is in good working condition. Regular cleaning and replacement of filter screen, fan blade and other parts of Roots blower can reduce the noise of the blower.
