Water-cooled Gasoline Generator Single Phase Gasoline Generator Set

water-cooled gasoline generator Gasoline generator noise is a broad-band spectral characteristics, and the requirements of muffler equipment can withstand high air velocity and high temperature, high pressure, and not afraid of water and humidity, when the temperature increases, the performance of muffler little change, according to this Situation, the use of multi-micro-perforated plate composite muffler. The micro-perforated plate muffler with 0.5 ~ 1mm hole diameter and 1 ~ 3% perforation rate with 0.5 ~ 1mm thin steel plate has good absorption effect on medium and high frequency noise. When the multilayer, the thickness of the cavity depends on the absorption band, low frequency 125 ~ 250Hz, the cavity thickness of 150 ~ 220mm, IF 500 ~ 1000Hz, the cavity is 80 ~ 120mm. For high-frequency 2000 ~ 4000Hz, the cavity is 30 ~ 50mm, in order to prevent micro-perforated plate cavity along the tube length of the sound wave propagation, the need for a higher muffler muffler, 0.5m long plus a lateral baffle . The cross-section of the double-layer micro-perforated tube-type muffler is circular.
