1、 Sound insulation and noise reduction methods for generators

In order to effectively solve these noise problems, we have summarized the specific methods for generator sound insulation and noise reduction as follows:

1. Install sound insulation walls between the generator and the room

The use of this method of adding soundproof walls will not affect the size of the generator space, nor will it affect the normal operation of the generator. The safety performance is relatively high, but if this measure is adopted, it will affect the size of the interior space of the owner's room.

Specific method: On the base wall of the generator inner wall, lay sound insulation cotton and nail steel wire mesh on the wooden keel, fix it and use cement sand for plastering. Adopting this approach can have a certain degree of sound insulation and absorption effect, but there may be some problems during construction, such as easy detachment of cement sand plaster, which require more attention.

2. Apply sound insulation treatment to the inner wall of the generator

When carrying out sound insulation and noise reduction treatment for the generator, it is possible to choose to lay a layer of sound insulation material on the inner wall of the shaft and then take protective measures on the outside.

Specific method: On the base layer of the inner wall of the generator, nail a layer of sound insulation material such as sound insulation felt. After laying the sound insulation material, it needs to be fixed with steel wire mesh and finally treated with cement mortar for plastering.

Compared to the first type, the second type uses soundproofing felt, and directly applies cement mortar on the steel wire mesh, which is not easy to peel off and has strong durability.

2、 Generator noise treatment

The working noise of a generator mainly includes the operating noise of the generator itself, pipeline resonance noise caused by generator operation, water flow movement and impact noise caused by generator operation. As motor noise, it mainly includes three parts: aerodynamic noise, mechanical noise, and electromagnetic noise. When the motor is operating, the aerodynamic noise is composed of the airflow noise of the cooling air and the noise of the high-speed rotating blades of the fan. Mechanical noise includes bearing noise and noise generated by structural vibration caused by unbalanced rotor of the motor due to "groove harmonic force". Electromagnetic noise is caused by the alternating electromagnetic attraction and hysteresis between the stator and rotor, and the main ways for pump room noise to be transmitted outward are through air and solid transmission.

To deal with generator noise, targeted treatment measures should be taken based on the characteristics of different noises, and comprehensive treatment of all equipment in the entire area should be carried out. Only treating a single pump cannot achieve the required effect. All pump equipment and pipelines need to be treated because after the treatment of the main noise equipment, the secondary noise equipment becomes prominent, and it also has noise pollution, This is a noteworthy point in governance.

3、 Methods for noise reduction treatment of generators

According to the characteristics of noise propagation, sound insulation and noise reduction methods can be mainly divided into the following categories:

1. To reduce noise sources, industrial and transportation industries can choose low-noise production equipment and improve production processes, or change the movement mode of noise sources.

2. Reduce noise in the transmission path, control the spread of noise, change the noise transmission path already emitted by the sound source, such as using sound absorption, sound insulation, sound barriers, vibration isolation and other noise management, as well as reasonable planning of urban and building layout. The principle of sound insulation and noise reduction is to use sound insulation components to separate the noise source from the receiver. The isolated noise propagates in the medium inside the isolation components and cannot be smoothly transmitted, achieving the goal of reducing noise. This is a commonly used method nowadays, which can be used for many fixed noise sources. Based on the requirements of sound insulation and the surrounding environment, it is determined which method or methods to choose for comprehensive treatment.

3. When measures cannot be taken to protect the noise of the listener or the receiving organ from the sound source and transmission route, or the acoustic measures taken still cannot achieve the expected effect, protective measures need to be taken for the listener or the receiving organ. For example, workers exposed to long-term occupational noise can wear ear protectors such as earplugs, earmuffs, or helmets.

The design of the sound insulation and noise reduction treatment plan needs to be based on the actual working conditions and requirements on site, such as the type of sound source, noise level and frequency, environmental and environmental requirements, ventilation and heat dissipation requirements, noise reduction targets, etc. The selection of appropriate sound insulation and absorption materials can effectively reduce noise pollution caused by various transportation, machinery, industrial production, etc. Noise problems can be seen everywhere. To effectively control noise, it is necessary to carefully analyze the sources and causes of noise. Only in this way can noise be significantly reduced, ensuring that people's lives, work, and health are not affected. At the same time, effective control of noise can also improve the competitiveness of products in the market, expand their social and economic benefits.
