In the context of increasingly stringent environmental protection requirements, the technical requirements of large-scale wind turbine noise control and shock absorption enterprises are also increasing. The environmental protection department's requirement for fan noise is that the noise of the fan should not exceed 85 decibels under normal operating conditions. Therefore, large-scale wind turbine noise control and shock absorption enterprises need to take effective technical measures to ensure that the wind turbine noise can meet environmental protection requirements.
In order to solve the noise problem of large wind turbines, large wind turbine noise control and shock absorption enterprises need to have an in-depth understanding of the working principle of wind turbines and the mechanism of noise generation. A large wind turbine is a device that converts mechanical energy into wind energy, and its working principle is to generate wind power through the rotation of the impeller. As the impeller rotates, it interacts with the surrounding air and generates aerodynamic noise. In addition, the mechanical parts of the wind turbine, such as bearings, gears, etc., also generate mechanical noise. Therefore, large-scale fan noise control and shock absorption enterprises need to start from two aspects: aerodynamics and machinery, and take effective measures to reduce fan noise.
First of all, for aerodynamic noise, large-scale fan noise control and shock absorption enterprises can adopt the method of optimizing blade design to reduce noise. By streamlining the blades, the roughness of the blade surface can be reduced, and the aerodynamic noise of the fan can be reduced. In addition, noise can be further reduced by adding *** or overall sound insulation treatment to the fan.
Secondly, for mechanical noise, large-scale wind turbine noise control and shock absorption enterprises need to start from the optimal design of mechanical components. By optimizing the design of bearings, gears and other mechanical parts to improve their lubrication effect and assembly accuracy, the vibration and friction of mechanical parts can be reduced, thereby reducing mechanical noise.
In addition to the above measures, large-scale fan noise control and shock absorption enterprises can also take the following methods to reduce fan noise: first, use high-strength materials to manufacture fan components to improve the rigidity and stability of the fan, thereby reducing vibration and noise;The second is to optimize the installation method of the fan to reduce the vibration and resonance of the fanThe third is to use advanced control technology to monitor and adjust the operating status of the fan in real time to maintain the stable operation of the fan.
In order to ensure that the technical measures of large-scale wind turbine noise control and damping enterprises can meet the requirements of environmental protection, it is also necessary to strengthen the supervision and evaluation of their technical level and treatment effect. The environmental protection department should strengthen the supervision of large-scale wind turbine noise control and shock absorption enterprises, and formulate strict technical standards and treatment requirements. At the same time, it is also necessary to establish a sound evaluation system to regularly evaluate and accept the treatment effect to ensure that the noise of the wind turbine can meet the environmental protection requirements.
To sum up, large-scale wind turbine noise control and shock absorption enterprises need to take a variety of measures in the control of fan noise, including optimizing design, using high-strength materials, optimizing installation methods, and adopting advanced control technology. At the same time, it is also necessary to strengthen technical supervision and evaluation to ensure that the treatment effect can meet the requirements of environmental protection. Only in this way can we meet people's growing demand for environmental protection and health, and promote the sustainable development of large-scale wind turbine noise control and shock absorption enterprises.
