Room isolation and noise canceling generators swing requires thorough isolation, to prevent premature failure. Cable connection should be soft. The main sources of noise are: intake system, exhaust gas turbocharger, combustion noise, cooling fan and secondary vibration. Noise noise propagation distance depends on the size and noise level around, most people find it difficult to distinguish the sound of 3dB (A) the difference between the two noise sources, however 6dB (A) was 2-fold difference in noise intensity, high-frequency noise is easy to hear precise testing requirements of environmental noise generators at least less than 10dB (A). If the system noise is too loud, it may exceed the allowed range of local regulations. Engine room crew from the impact. Near the area: a distance greater than 2 times the noise field, the noise level changes greatly; free area: Estimated noise level - from the 2 fold decrease 6dB (A); reflection region: free area, near the reflection region. Noising measures local regulations often dictate neighborhood noise restrictions at 40 ~ 50dB (A), because after the treatment is very expensive, noise problems for neighboring generators need to be planned in advance. When the generator set is running, the engine room of the facility require hearing protection, the noise should meet OSHA standards. Noise source to the recipient should be ready isolation, establish realistic goals, measure and predict noise levels, noise cancellation assess needs. Effective noise cancellation depends on the hardness of the walls, the effective open area, showing the noise channel, sound-absorbing materials used, reflection noise and noise leakage. The net figure is usually a good cover to reduce air flow through the housing. Measures to eliminate noise scene are: ① increasing access to distance. According to quickly estimate the distance increased by 2 times, noise reduction 6dB (A). ② added high-density sound-absorbing materials, changing the direction of the noise, attention harder reflective surface. Quickly estimate, two identical reflection wall will increase noise 3dB (A). In short, everything to isolate the unit. Several Issues brief diesel generator set installed when the need to note: the location of the installation in place with good ventilation is needed, the generator must have sufficient air inlet, have a good diesel engine at the outlet. Generator rental installation site should be kept clean, generator rental where, to avoid corrosive substances, but also around the fire-fighting equipment. When used indoors, as well as outside the channel must have exhaust pipe, tobacco pipe elbow is best not more than three, to ensure the smooth flow of exhaust gas, and pipeline export 5-10 degrees downward, to avoid the rain injection, quiet power rental, if it is necessary to have vertical rain cover. Housing unit must be connected to ground protection, diesel generator rental, the need for a neutral point directly to ground generators, generator rental Wenchang, have professionals neutral ground, and then configure the lightning protection devices. Generators have time to install a two-way switch must be very reliable for the job, or will send down power, resulting in an accident. Silent generator rental, the diesel generator (online consultation), Wenchang generator rental Dongguan Shangwang firewood provided by the Electrical and Mechanical Equipment Co. Dongguan Shangwang diesel Electrical Equipment Co. (www.dongguanfadianji.cn) is an industry leader in Dongguan, Guangdong, diesel generator sets, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. On the diesel generator leadership with the staff warmly welcome all inquiries negotiations to create a better future for diesel generators.
