Noise reduction project of diesel generator set
Wuhan Wacker Power Technology Co., Ltd. is a comprehensive enterprise specializing in the research and development, production, sales and service of diesel generator sets in Hubei. Noise works. Serving Wuhan, Hubei and surrounding cities, Huanggang, Tianmen, Xiaogan, Yingcheng, Xiantao, Jingshan, Yunmeng, etc., there are model projects in all regions for visits and inspections!
Unit noise reduction treatment is to ensure that the ventilation environment of the generator set does not reduce the output power and normal operation of the equipment. It uses high-efficiency sound-absorbing materials and noise reduction and noise reduction devices to control the intake and exhaust channels and the exhaust system. Sound reduction, sound absorption, vibration isolation and other technical means are used to reduce noise so that noise emissions meet national environmental protection standards. So as to effectively achieve the noise control of industrial equipment such as stationary generators.
Noise source analysis
When the diesel generator set is running, the noise mainly includes engine exhaust noise, intake noise, combustion noise, mechanical noise caused by reciprocating high-speed movement and impact of moving parts such as connecting rods, pistons, gears during work, and cooling water exhaust fan airflow. noise.
Extracted from the "Environmental Noise Pollution Prevention Law of the People's Republic of China", the Urban Area Environmental Noise Standard of the People's Republic of China: This standard specifies the highest value of environmental noise in five types of urban areas, applicable to urban areas, and rural living areas can be implemented with reference to this standard.
|Standard value of urban environmental noise|
Areas in need of quiet, such as wellness areas, luxury villa areas, luxury hotel areas, etc.
Areas mainly for residential, cultural and educational institutions
Residential, commercial, industrial mixed zone
Traffic arterial roads in cities and areas on both sides of inland waterways crossing urban areas
Main noise reduction measures
○ Smoke exhaust noise measures: install resistive industrial mufflers and resistant residential mufflers;
○ Intake and exhaust noise reduction measures: increase the corners of the intake and exhaust channels, and set the intake and exhaust noise reduction boxes (composed of silencer film);
○ Inside the machine room: use special brick walls and paving sound insulation panels, and install soundproof doors;
○ Increase the base quality of the unit or vibration isolation trench for vibration isolation treatment.
