1, Sound insulation and noise reduction of workshop-workshop building:
Under the condition of ensuring the rationality of the infrastructure layout of the production workshop, the mechanical equipment room and workshop should be provided with sound absorption and insulation layers, sound insulation doors and windows, and the workshop should be divided into areas and equipped with precision equipment that meets the seismic requirements. Minimize the influence of noise and vibration on the surrounding environment, so as to better realize the sound insulation and noise reduction of the factory building.
2. Sound insulation and noise reduction of workshop-foundation excavation:
During foundation excavation, vibration isolation should be carried out. If a vibration isolation trench with a depth of 1m and a width of 0.4 m is dug around the foundation, a rubber damping pad is added above the damping layer, and other necessary treatments are made on the rubber damping pad. Finally, the vibration isolation trench should be paved with steel plates to reduce noise.
3. Sound insulation and noise reduction in the workshop-installation of equipment sound insulation cover.
For machinery and equipment with noise as the main source, it is necessary to reduce noise radiation from the noise source and install sound insulation cover, which can make other noise control measures play a greater role, thus improving the overall sound insulation and noise reduction effect. Due to the different requirements of sound source equipment for sound source type, overall size, ventilation and heat dissipation, it is necessary to conduct on-site investigation, analysis, design scheme, and manufacture sound insulation cover.
Multi-purpose points of soundproof room fabric;
It is also a common and effective method to eliminate noise with fabric. The test shows that the sound absorption effect of suspended and flat-laid fabrics is the same, such as curtains and carpets, and the sound insulation effect of curtains is obvious. The soft touch of the carpet can not only produce a comfortable and warm feeling, but also eliminate footsteps.
When installing equipment, it is necessary to do shock absorption design and design shock absorption treatment according to the weight and vibration frequency of the equipment. Vibration isolation and shock absorption measures can be taken at the bottom of the equipment. Specific measures commonly used shock absorption products include shock absorption rubber, spring shock absorber, rubber shock absorber and shock absorption platform.
According to the connection mode of seismic source and supporting seismic source, the seismic design can be divided into two ways: active seismic reduction and passive seismic reduction. According to the different vibration modes, solid isolation and damping can be used to control the vibration. The selection of damping materials requires professional analysis, formulation of corresponding damping technical scheme and selection of correct damping products.
