Diesel generators noise too annoying? The solution is here!
There are some places that need to use diesel generators, so some people complain that the noise is too loud. In fact, there are many sources of noise, and there are corresponding solutions. Next, BTMA will introduce how to solve the problem of high noise of diesel generators . Ⅰ. Sources of noise from diesel generators 1. Emanating from the engine case The general frequency is about 500-3KHz, and the noise value varies under different engine speeds. Generally, when the speed increases by 2 times, the noise value increases by about 9-12 decibels. 2. Spill from the air inlet and outlet There is a difference of about 10-15 decibels under no load, and the specific noise characteristic is that the noise value of the 2k-4k frequency is the largest. 3. From the engine exhaust The difference is about 10-15 decibels with or without load, and the main frequency noise is (speed/60)x(number of cylinders/2). 4. From the cooling fan and other ancillary equipment The noise value of this part is smal...
