Description

Technical Field

[0001] The utility model relates to the technical field of diesel generator sets, in particular to a super silent diesel generator set. Background Technique

[0002] A diesel generator set is a rigid whole composed of a diesel engine as the power source, a generator, a control panel, a common base and other components. A low-noise diesel generator set is a type of diesel generator set, which is widely used in power supply places with strict noise requirements such as post and telecommunications, communication, hotels, entertainment, hospitals, schools, high-rise buildings and industrial and mining enterprises.

[0003] When the diesel generator set is working, it is easy to vibrate. During the vibration process, it collides with the inner cavity of the waterproof box and generates noise. The generation of noise deteriorates the working environment quality of the device and reduces the use effect of the device. In addition, when the diesel generator set is working, it is generally cooled by a cooling fan. However, when the air inlet is admitting air, external dust or impurities are blocked outside by the filter screen. Over time, the ventilation efficiency of the filter screen is reduced, affecting the cooling effect of the diesel generator set.

[0004] Therefore, we propose a super silent diesel generator set to solve the problems mentioned above. Content of the Utility Model
