点击量: 3 Release time: 2019-11-25 Clicks: 3

The diesel generator itself is relatively noisy. In actual application, it is easy to cause serious noise pollution to the surrounding environment. Due to the relatively complicated noise mechanism of a diesel generator set , once it is applied to practice, it is easy to cause serious consequences due to serious noise problems. Especially for military warfare, if this kind of generator set with high noise is applied to it, it will cause unimaginable consequences. Therefore, in view of this phenomenon, in the specific operation process, it is necessary to scientifically and reasonably control the noise problem of diesel generators. In order to ensure the control effect, the water-cooled silencing technology can be effectively used, which will not only help achieve effective control of the generator set noise, but also achieve the fundamental purpose of reducing temperature and noise. 1 The scientific design of the internal structure of the generating set At this stage, the domestic development of water-cooled noise reduction technology in China is still in its infancy, and it is necessary to continue to conduct in-depth research on the technology in practice, which will not only help the function and value of the technology Fully excavated, and it can really play a good role in controlling the noise reduction problem of China's generating units. When designing the internal structure of the silent diesel generator set, it needs to be combined with reality to be able to propose targeted control measures. Resistive mufflers can play a good role in controlling some low-frequency noises during practical application, while resistive mufflers can play a certain role in controlling some high-frequency noises when in use. Therefore, by comprehensively analyzing this phenomenon, it can be seen that combining the two can realize the design of a composite muffler device, which is beneficial to the effective control of low-frequency noise and high-frequency noise. On this basis, by adding a corresponding water-cooled circulation heat dissipation structure, a water-cooled muffler with composite characteristics can be formed [1]. On the basis of ensuring that the thermal radiation of the muffler is reduced, the noise control effect can be ensured to the greatest extent. Water-cooled generators with composite characteristics must be operated through scientific and reasonable design concepts during the internal structure design and specific implementation . At the same time, it is necessary to design the pipes according to the requirements of different specifications and models in accordance with the actual situation to achieve the fundamental purpose of noise reduction. 2 Scientific selection of raw materials When diesel generators use water cooling technology to achieve silence, attention needs to be paid to the effectiveness and pertinence of the raw materials in the selection process. As the generator set itself generates very high temperatures during operation, and the exhaust gas generated after operation also has certain corrosive characteristics, therefore, under this prerequisite, the material of the water-cooled muffler device needs to be given. Extra attention and attention. When selecting the relevant materials for the water-cooled muffler device, it must not only have good heat resistance, but also be resistant to corrosion, and it must also have the ability to resist the impact of strong airflow. In addition, because the generator set itself generates very powerful power during operation, it will also be affected by some external conditions and natural factors. Therefore, the material of the water-cooled muffler must not only ensure good structural quality, but also It also needs to have some anti-rust function. Therefore, when selecting water-cooled sound-absorbing materials, comprehensive consideration must be given to various factors such as actual construction, and some materials with high cost performance are selected as much as possible [2]. Such as polyurethane-based acoustic foam, etc., this material has a very good sound absorption effect, especially when the noise is at 500 ~ 2000Hz, the octave band muffler volume of the acoustic foam itself will be in a relatively good state. If the analysis and research is based on the actual changes in noise frequency, the amount of sound attenuation can be regarded as an inverted U-shaped curve in practice. In this state, the overall appearance and specifications of the acoustic foam will become larger and larger. However, it is worth noting that the control of the volume of the muffler by the muffler layer of the acoustic foam shows a downward trend, and the two present an inverse state. 3 Scientific Control of Noise Reduction and Heat Dissipation When analyzing and researching the actual application of the water-cooling technology of silent diesel generator sets, it will inevitably involve the design and use of related equipment and devices. In order to ensure the use effect, it is necessary to quickly cool the temperature of the generator set while ensuring that the muffler has a good control effect on noise. Water cooling technology can achieve this goal in practical application, because when the exhaust gas gradually enters the inner cavity of the water-cooled muffler device from the intake position of the muffler, the inner cavity and the shell of the muffler itself appear to be certain. influences. In response to this phenomenon, in the specific operation process, scientific and reasonable measures must be adopted to control the volume of the water jacket. This will not only help achieve effective control of the water circulation speed, but also ensure that the entire water-cooled muffler system is in operation. Validity and stability in [3]. 4 Conclusion In conclusion, the practical application of water-cooling technology in silent diesel generator sets has a very important impact and use. Not only can it really play a good role in noise control, but it can also provide the normal, safe and stable operation of the generator set. Effective protection. Therefore, in the future design of the internal structure of the generator set, water cooling technology should be appropriately applied to ensure the reasonable selection of materials and provide guarantee for the noise reduction control of the generator set.
