Super-silent diesel generator set with small size

Abstract

The invention relates to a super-silent diesel generator set with a small size. The super-silent diesel generator set mainly comprises a diesel engine, a generator, a water-cooled muffler, a chassis and a radiator, wherein the diesel engine, the generator and the water-cooled muffler are all fixed on the set chassis and are isolated from the external environment through a mute cover; the chassis is connected with the mute cover through detachable locks, and the radiator is mounted outside the mute cover and is connected with a cooling liquid sleeve of the diesel engine through a water inlet tube and a water outlet tube to form a cooling circulation loop; a smoke outlet of the diesel engine is connected with the water-cooled muffler through a water-cooled exhaust manifold. Directed at the noise source of the diesel engine, the super-silent diesel generator set adopts the mute cover for noise control partitioning, the mute cover can play a quite good role in sound absorption and sound insulation during the operation of the set, and the size of the set is greatly reduced because the radiator is moved out.

Description

technical field [0001] The invention relates to a diesel generator set, more specifically to a small-volume ultra-quiet diesel generator set. It belongs to the manufacturing field of silent diesel generators. Background technique [0002] Diesel generator set is a kind of power generation equipment with diesel as the main fuel. The diesel engine is used as the driving force to drive the generator (ie electric ball) to generate electricity and convert kinetic energy into electrical energy and thermal energy. Diesel generator sets have the disadvantages of large vibration and high noise during operation. In order to reduce the noise of the diesel generator set, the general silent diesel generator set is equipped with a silent cover. The engine, generator, radiator and control system of the diesel generator set are all installed inside the silent cover, and the noise reduction entrance and exit are set inside the silent cover. Air duct, etc., to reduce the noise emitted by th...

AI Technical Summary

Problems solved by technology

[0003] At present, in order to achieve a certain noise reduction effect for diesel generator sets, it is usually necessary to install a relatively large silent cover, and paste a certain thickness of sound-absorbing cotton inside the silent cover, making the entire unit large in size and heavy in weight.

At the same time, the engine, generator, radiator and control system of the unit are all installed in the silent cover, which makes the installation and mobility of the diesel generator set poor.
