Products Description

1.JFH type series acoustic shield 
    The equipment whose major noise is directly transmitted via air, such as steam turbines, pumps, coal grinding mills, fans , etc., can be equipped with the JFH series acoustic shield to achieve the purpose of noise reduction. The acoustic shield has a relatively large sound transmission loss and it is able to meet the requirements of equipment for safe operation, inspection, patrol inspection, lighting .  
     Acoustic insulation elements are designed in accordance with acoustic principles and bring the best sound absorption, shock absorption and sound insulation functions into play. According to the noise frequency spectrum characteristics of equipment, obtain the opening distribution and punching rate of perforated steel plates; the overall air leakage rate of enclosure is less than 0.2‰. The damping layer can withstand the high temperature more than 100℃. The sound transmission loss of acoustic insulation element is more than 32dB. The acoustic shield has a combined modular structure and a convenient transportation, installation and removal .
IPGX type series silencer
 
 
 
    For the equipment whose major noise is transmitted outwards by means of air exhaust, such as small-sized gas turbines, diesel engines , etc., silencers can be mounted on their air outlets.
    The IPGX gas silencer is suitable for the transmission situation of the noise which is generated inside gas turbines and transmitted from tail flue to surroundings. Its applicable temperature is ≤600℃ and its noise reduction function can achieve 75Db(A)/m. At present, our institute is a major supplier for global purchase of GE (Jenbacher) Company.
