Description

Technical Field

[0001] The utility model discloses a noise elimination device, belonging to the technical field of compressor noise elimination equipment, and specifically relating to a noise elimination device for compressor commissioning. Background Art

[0002] A compressor is a special type of compressor, widely used in air conditioners, refrigerators and other refrigeration equipment. Its name comes from the complexity of its internal structure, which is similar to a maze. The compressor improves the compression efficiency through multiple maze-shaped compression chambers, and can complete an efficient compression process within a relatively small volume. Due to its design and working principle, the compressor usually runs with lower noise than other types of compressors. This compressor mainly uses a rotating maze shape to gradually compress the gas. Compared with traditional piston or screw compressors, the compressor may provide better performance and efficiency in specific applications. Compressor commissioning is a key test process to ensure that the compressor can operate stably and efficiently in actual use. During traditional compressor commissioning operations, a large amount of noise is generated, and workers need to wear earplugs to reduce the harm of noise. However, such long-term work will inevitably cause certain damage to the ears. Therefore, there is an urgent need for a noise elimination device to reduce the noise of compressor commissioning, thereby protecting the safety of workers. Content of the Utility Model
