Tianjin muffler muffler _ _ Dingrui air conditioning

 Muffler Performance Performance: Impedance Muffler volume: low-10-15dB (A), IF 15-25 dB (A) Urumqi muffler, high-frequency 25-30dB (A) the average drag coefficient of 0.4. Muffler silencer elbow, short arm elbow silencer: low-5-10dB (A), IF 10-15 dB (A), Zhejiang muffler, high-frequency 15-20dB (A); in the long arm bent silencer Head: low-5-8dB (A), high-frequency 8-12 dB. Technical improvements: impedance composite muffler made the following restructuring on the basis of the original national standard T701-6 on: a) the change of the use of high quality galvanized sheet steel to meet corrosion requirements. b) repeal wooden keel instead of steel keel to meet fire safety requirements. c) fine glass wool insulation to centrifugal glass wool felt, the proportion increased to 32 kg / m3, in order to avoid blowing process, sound-absorbing material is evacuated, resulting in ineffective and pollute the environment. d) Facing increased perforation protection panel, increase the intensity of sound-absorbing sheet to prevent splashing sound-absorbing material, resulting in personal injury. e) sound-absorbing sheet for vertical installation, to prevent dust and reduce silencing effect. T701 T701 Impedance Impedance complex muffler muffler is a composite made from superfine wool muffler Tianjin sound absorption resistance of high frequency has a good effect silencer, muffler is a mutation in the passenger section and the outer pipe of action between the expansion chamber composed of low-frequency noise and some role in an effective silencer. 1, the muffler - at rated wind, low-volume muffler for 10-15dB (A), IF muffler is 15-25dB (A), the amount of high-frequency silencer 25-30dB) (A). 2, the resistance loss - rated air flow, the average drag coefficient ε = 0.4. Losses under different wind resistance by ΔΡ = ε × V2 / 2g × (mmH2O) calculations.
