How To Control The Noise Generated By The Bridge Cutting Machine?

In principle, the control of the noise generated by the bridge cutting machine when cutting stone is roughly similar to the control of general noise, which is based on the principle that only when the three factors of sound source, sound Pathogen transmission and acceptance exist at the same time can the noise cause interference and harm to listeners, try to control one or several of them to achieve the purpose of reducing noise. However, stone cutting has its unique process characteristics, and in specific implementation, multiple indicators such as specific circumstances, technical conditions, and economic effects should be comprehensively considered in order to come up with a more effective solution. The noise control generated during the stone cutting of the bridge cutting machine should start from the following three points:
1. Reduce sound source noise. Improving the manufacturing process and installation accuracy of the bridge cutting machine, improving the dynamic balance of rotating parts, selecting reasonable cutting process parameters, and designing low noise structures are important components of reducing sound source noise, especially suppressing the vibration of the saw blade, which is an effective way to reduce sound source noise.
2. Protect workers from noise hazards. Adopting this method is relatively passive and ineffective, but due to its economy and convenience, it can also be considered as one of the means of noise control in situations where noise cannot be reduced temporarily. The main method is to insert soundproof cotton into the earholes of the operators, wear soundproof earplugs or wear noise prevention equipment such as earmuffs and helmets to reduce the harm of noise to the human ear.
3. Adopting methods to block and shield the propagation of sound waves, such as sound insulation, absorption, and noise reduction devices. In recent years, the foreign bridge cutting machine industry has combined protective safety covers with sound insulation covers to reduce the harm of noise to operators.
