  • High Quality Acoustical And Noise Enclosures From China - China

    price: 5000.00 Dollar US$

    Sound Reduction Hood contain One-piece Sound Reduction Hood and Fabricated Sound Reduction Hood.
    Sound insulation hood is an advisable and effective noise reduction measure, which can enclose the device with higher noise to effectively impede the outward transmission and diffusion of noise, and reduce the effect of noise on environment. Sound level difference between internal and external sound insulation hood is 20-30dB(A).
    Sound insulation hood shell is generally made from metal materials with a certain weight and rigidity, and usually adopts 1.5~3mm thick galvanized steel plate and stainless steel plate, etc. A layer of damping layer can be set on the plate to reduce the vibration of plate, and improve the sound insulation property of sound insulation hood.
    As for the equipment which needs heat dissipation, necessary ventilation duct should be reserved on the sound insulation hood. This duct must be provided with silencer. Equipment process and maintenance requirements must be met during the design of sound insulation hood. For example, chain hoist is set in the sound reduction hood for equipment overhaul use.
    Sound insulation hood is mainly applicable to the equipment which needs noise reduction, e.g. air compressor, natural gas compressor, diesel engine, gas turbine, steam turbine, motor, water pump, fan and other noisy equipment.
    One-piece sound reduction hood is a sound reduction hood that the whole hood or main structure is fabricated as a whole, in which steel structure skeleton, wall and roof are generally fabricated as a whole, and silencer, sound insulation door and sound insulation window can be fabricated with main body of sound reduction hood as a whole, but also can be separately fabricated and then assembled on the site.
    Fabricated sound reduction hood is a set of noise reduction equipment that all components of sound reduction hood are prefabricated in the factory and then assembled on the site. Sound reduction hood produced by our company now has achieved design standardization, batch fabrication, product seriation and installation modularization, which greatly improve the quality of sound reduction hood, and reduce the cost of sound reduction hood.
    Property: the rigidity and sealing property of hood body are very good as one-piece sound reduction hood is fabricated as a whole. Hence, one-piece sound reduction hood has good noise reduction property, and noise reduction quantity can be up to 25—35dB(A).
    Installation: one-piece sound reduction hood is fabricated as a whole, and the connection interface between sound reduction hood and noisy equipment is arranged on the mounting base. As there is less installation interface, the installation now is simple, and a set of one-piece sound reduction hood can generally be installed within 1~2h.
    Installation: fabricated sound reduction hood adopts standard connection mode, and all components adopt plug-in connection or bolted connection without flame operation on the site. The installation now is simple, and a set of fabricated sound reduction hood can generally be installed within 1~2 days.
    Transport: one-piece sound reduction hood has higher transport requirements, and must be transported as a whole since it is fabricated as a whole. However, there is superwide and superhigh risk, and the space in the hood can't be reasonably utilized, so more space is wasted, and transport cost is higher.
    Universality: one-piece sound reduction hood has stronger targeted design, and can only be used for noisy equipment or those with very close overall dimension.
    fabricated sound reduction hood :
    all components of sound reduction hood are designed and fabricated in a standard mode, and standardized sound insulation door, sound absorption/insulation wall, silencer and universal components can be applied on sound reduction hood of any hood.
