Description

Technical Field

[0001] The invention relates to the technical field of silent generator sets, and in particular to a mounting structure of a silent mobile generator set. Background Art

[0002] At present, there are three main ways to reduce the noise of the unit: sound insulation, sound absorption and silence. Some generator sets use a whole-machine soundproof cover to reduce noise, which can reduce noise by 10-35dB (A), but there is a problem of not being conducive to ventilation and heat dissipation; some generator sets reduce noise by increasing the thickness of the sound-absorbing cotton inside the soundproof cover. In this way, the effective space of the generator set becomes smaller, and the sound-absorbing cotton also has the problem of pollution to the human body and the environment; some generator sets use air intake and exhaust noise reduction boxes to silence noise. Silencing is contradictory to air volume. The more complex the silencer structure, the smaller the air intake and exhaust volume will be, affecting the normal operation of the unit. At present, there is no standard method for direct noise reduction. Noise reduction mainly relies on the reasonable layout and structural improvement design of the generator set.
