The production of wind power forging is an industry with high energy consumption and high noise. In the production process, due to equipment operation, material impact and processing, a lot of noise will be generated. Noise not only endangers the health of employees, but also causes noise pollution to the surrounding environment. Therefore, the research on the noise control and noise reduction technology of wind power forging production has important practical significance for protecting the health of employees and the surrounding environment.
The cause of noise
The noise in wind power forging production is mainly caused by the following reasons:
Equipment operation: The operation of fans, hydraulic presses, stamping machines and other equipment will produce high-frequency or low-frequency noise.
Material impact: forging in the process of processing, due to high-speed impact and collision will produce high energy noise.
Processing process: cutting, grinding, punching and other processing processes will also produce the corresponding noise.
In view of the above causes of noise, the following measures can be taken to control and reduce noise:
Optimized equipment design: low noise design and manufacturing process is used to reduce the noise of equipment operation.
Protection of impact parts: Protect and slow the impact speed of the impact parts in the forging process to reduce noise.
Improve the processing technology: by optimizing the cutting parameters, the selection of low noise tools and other measures to reduce the noise of the processing process.
Noise control technique
Noise control technology is mainly divided into two categories: noise source control and noise propagation control.
Noise source control: reduce the intensity of noise source by improving equipment design and optimizing process flow. For example, low noise fan design and manufacturing processes are used to reduce noise during fan operation.
Noise propagation control: through the use of sound absorption, sound insulation, muffler and other equipment or materials to block or reduce the transmission of noise. For example, sound absorbing materials or mufflers are installed around the fan to reduce the impact of noise on the surrounding environment.
In practical application, appropriate noise control technology should be selected according to the specific production environment and noise characteristics. For example, measures such as sound-absorbing walls and mufflers can be adopted in the fan room to reduce indoor noise; In the forging processing area, measures such as sound insulation cover and soundproof door can be adopted to block the noise transmission.
Noise reduction technology
Noise reduction technology is mainly divided into two categories: active noise reduction and passive noise reduction.
Active noise reduction: Through the use of electronic technology and acoustic technology to cancel out the noise of sound waves. For example, devices such as noise cancelers or active noise-cancelling headphones are used to reduce or eliminate noise by generating sound waves opposite to the original noise.
Passive noise reduction: through the use of various sound insulation materials and sound insulation structures, block the propagation path of noise. For example, passive sound insulation measures such as soundproof walls, soundproof doors and soundproof Windows are used to reduce the spread of noise.
In practical application, appropriate noise reduction technology should be selected according to specific noise reduction requirements and environmental characteristics. For example, passive noise reduction measures can be adopted in the forging processing area, such as the installation of soundproof doors and soundproof walls; Active noise reduction measures such as noise cancelers can be adopted in employee rest areas.
outlook
With the continuous progress of science and technology and the continuous innovation of application technology, the noise control and noise reduction technology of wind power forging production will have a broader development prospect. In the future, there will be more efficient, intelligent and environmentally friendly noise control and noise reduction technology to provide more reliable technical support for the sustainable development of wind power forging production. At the same time, with the continuous improvement of people’s environmental awareness and the continuous pursuit of a healthy living environment, the noise control and noise reduction technology of wind power forging production will be more widely concerned and applied.
