Muffler is effective aerodynamic control equipment noise out of the spread until the interior for the acoustic treatment, can greatly reduce noise generation and propagation, and does not affect the air flow through. After installing mufflers, muffler equipment should reach 20-40dB (A), subjective perceived loudness effect a corresponding decrease 50-90%. Roots blower installation because it is high-speed operation of the machine, it will shake mine produces the oxygen blower, and because of its internal air pulsation around, but also increased the blower vibration, so needs to be fixed when the blower is installed on the ground. According to the model of small blower fan, fan size on the ground by digging at a position corresponding to 150 * 150mm square and 300mm deep square pit and buried bolt, and bolts and nuts to connect the blower fan by price, Finally, fill the pit in square concrete, concrete and other fixed later, and then forced to tighten the nut Roots blower, a fan base and concrete firmly connected together, so that you can reduce the blower in operation vibration displacement, improve the operational safety of the equipment, and by reducing the vibration, thus greatly extending the life of the fan.
