Introduction to 1.
Generating units, air conditioners, air compressors or other sports machinery work or other sound sources produce a lot of noise, and its sound value is as high as 118 decibels, causing serious environmental pollution, affecting people's normal work and life, and destroying human physical and mental health. The company is to make these sound sound source into a dumb silencer engineering experts.
Scope of 2. noise control
1, generator room, air compressor room, central air conditioning room, industrial refrigeration room, sports machinery room and other industrial production sites.
2. Noise control of mechanical and electrical equipment in high noise production workshop.
3, karaoke hall, opera house, office building and other cultural and entertainment places.
4, high requirements of ultra-quiet, low noise or no noise, laboratory, research room, etc.
Technical requirements for silencing works of 3. generator room
1. Air intake system: Each generator set needs a lot of fresh air when it works, which is mainly used for diesel engine combustion and electric ball cooling.
2. Exhaust system: When the diesel engine is working, it generates a lot of heat. This heat should be pumped (discharged) out of the machine room to ensure that the temperature of the machine room does not exceed 50 degrees, providing a normal working environment for the generator set.
3. The silencing project of the machine room must refer to the scientific and technical parameters such as the air demand, exhaust gas emissions, and heat emission requirements of the diesel generator set to design a reasonable air intake and exhaust area.
Brief introduction of silencing principle of 4. generator room
The noise control project of Yongdaxing Company adopts the principle of treating both symptoms and root causes. The noise control project is designed and constructed from the aspects of noise elimination, sound absorption, shock absorption and sound insulation from the entrance and exit doors of the engine room, diesel engine air intake system, water tank heat dissipation and exhaust system and smoke exhaust system of waste smoke pipe. The noise to be discharged from the engine room is effectively and comprehensively controlled in all ways. According to user requirements, sound absorption and sound insulation measures can be taken on the ceiling and four walls of the machine room to reduce the noise in the machine room. In order to ensure that the room temperature and the working temperature of the diesel engine will not rise, forced ventilation and exhaust measures are taken. The fresh air required by the generator can be replenished in time, and the dirty and hot air can be discharged in time. The company is equipped with silencer board, silencer plate and shock-absorbing sound absorption plate in the air inlet and exhaust channels. The installation of a secondary silencer in the exhaust pipe, its technical content, silencing effect and degree of specialization have been well received by the majority of users for many years.
The noise is reduced to a minimum by the silencer duct, which has a brick wall structure on the outside and an acoustic panel on the inside.
5. Yongdaxing company's service tenet:
"Strict compliance, scientific design, meticulous construction, low cost, and high-quality after-sales service" is the service tenet of Shenzhen Yongdaxing Company. We will send professional engineers to conduct field visits according to the specific layout of the computer room to provide users with the best design plan. Shenzhen Yongdaxing company to undertake silencer works are free of charge warranty for two years, and provide permanent service.
1, after the completion of the project, control the equipment engineering drawings, on-site to your equipment manager (responsible person) for training guidance, operation practice.
2. Quality tracking service shall be conducted once a month, and Party A shall be notified of hidden dangers in time and handled according to Party A's requirements.
3. Establish complete equipment operation and maintenance data in the computer to facilitate tracking services and improve maintenance efficiency. No matter when the fault occurs, Party B shall send personnel to the scene within 12 hours after receiving the fault notice to eliminate the fault.
4. Quality requirements:
The silencing works undertaken by our company must achieve the function of product introduction. All materials are national standard products, and parts are consistent with product standards.
5. Project duration:
From the date of construction according to the size of the project to determine the working day of completion.
6. Acceptance criteria:
It is 1 meter away from the factory boundary and 0.5 high. The daytime noise is less than 65 points and the sudden noise is not more than 15 points. The temperature at the control surface of the unit shall not exceed 4-8 degrees Celsius of the outside temperature.
