Mechanical and electrical equipment noise reduction equipment sound insulation cove

  Mechanical and electrical equipment noise reduction equipment acoustic enclosure , Roots fan silencing room Roots fan sound insulation cover can be used to reduce the inlet / exhaust noise of various fans, as well as the noise reduction and silencing room of exhaust pipe and other high-pressure fans
Fan is a kind of general mechanical equipment, which has a wide range of applications
The sales of electric power, mining, machinery, metallurgy, chemical industry and other industries are inseparable from fan The noise produced by fans in operation often becomes a disaster source affecting workers' health and disturbing the environment
In particular, the aerodynamic noise radiated by the air inlet and outlet of the fan adjacent to the living area is the main factor polluting the environment and forms a public hazard
It is one of the main objects of noise pollution control by China's industrial departments in recent years Industrial fan belongs to continuous operation equipment
The noise standard specified by the international organization for Standardization (ISO) for such equipment is & le; 90 dB, which is the same as the new standard in China, which is also the basis for the continuous noise standard of industrial enterprises
However, without noise elimination measures, the noise emitted by the fan inlet and outlet to the environment can reach 110 ~ 120 dB, which greatly exceeds the standard requirements
The silencing room series products are impedance acoustic flow type
According to the near characteristic data obtained from the actual test of the noise sources on the operation site of various fans in the power plant, determine the amount of sound attenuation required in which spectrum range as the main basis for the design of sound-absorbing sheet structure and fluid channel
At the same time, a narrow rectangular channel with large sound-absorbing material finish is adopted to enhance the absorption effect We know that when the noise source of the fan is at the z-large noise level, there are often more than one spectrum value, and the requirements for noise elimination are different for different spectrum bands
Therefore, the product adopts the resistive structure that plays the role of silencing high and medium frequency noise and the anti structure that plays the role of silencing medium and low frequency noise
At the same time, two kinds of silencing areas of high frequency and low frequency are adopted in the resistive channel to Z greatly broaden the silencing frequency band to achieve good silencing effect Roots fan silencing room is mainly used for various series of high-pressure centrifugal fans to reduce aerodynamic noise such as air inlet and outlet
When the user installs this product as required, its j-limit noise level will not exceed 85 ~ 90 dB
Roots blower silencing room roots blower sound insulation cover , Every part of the company's products has a perfect quality inspection process, especially the whole machine intelligent detection center, which detects the flow, pressure and temperature of each fan, and the company Yongjiu keeps the information of each fan to ensure that each fan is traceable and * to provide guarantee for maintenance in the process of future use
Free maintenance for life
