Method for controlling noise of mute generator set

Silent type generator set noise control for mute generator set is introduced to absorb low noise generator sets of advanced foreign technology and develop new products, its low noise, widely used in telecommunications, hotel buildings, places of entertainment, hospital, shopping malls, industrial and mining enterprises and other places where strict in environmental noise, then how silent type generator set noise control?


Under the premise of ensuring the ventilation conditions of the diesel generator set, that is, without reducing the output power, the intake and exhaust air channels and exhaust system are de-noised with efficient sound-absorbing materials and noise-reducing devices, so that the noise emission reaches the national standard of 85dB.


1, reduce exhaust noise. Exhaust noise is the main noise source of the unit, which is characterized by high noise level, fast exhaust speed and difficult control. The use of special impedance type of composite muffler, generally can reduce exhaust noise 40-60dB.


2, reduce the noise of axial flow fan. Two problems must be considered when reducing the noise of cooling fan of generator set. One is the pressure loss allowed by exhaust channel. The second is the amount of noise reduction required. In view of the above two points, can choose resistive plate muffler?


The air inlet should be set in the same straight line with the generator set and the air outlet. The air inlet should be equipped with a resistance plate muffler. Because the pressure loss of the air inlet is also within the allowable range, the air inlet and outlet volume in the machine room can be naturally balanced, and the ventilation and heat dissipation effect is obvious. ? The indoor air exchange and good sound insulation in the machine room will prevent the air in the room from convection when the closed water-cooled generator set is shut down, and the high temperature in the room can not be lowered in time. Low noise axial flow fan and resistive plate muffler can be used.
