An engine-driven generator set

Abstract

An engine-driven generator set, comprising: a soundproof box, the soundproof box is composed of an upper cover, a side wall and a chassis, and the chassis is provided with: an engine, and a cooling air guide to the engine is provided at the side inlet of the engine. Engine cooling fan; generator, the connection between the generator and the engine is provided with a cooling fan that guides the cooling air to the generator; the exhaust muffler is arranged on the rear side of the generator, parallel to the axis of the generator; the exhaust One end of the muffler is connected to the engine through an exhaust pipe; a hot air exhaust chamber is also provided in the soundproof box, and the hot air exhaust chamber is composed of a side plate, a cover plate and an engine speed control seat, and the engine cylinder head , the cylinder body and part of the exhaust pipe are enclosed inside; the rear side of the hot air exhaust chamber is provided with an opening, and the opening is connected to the first exhaust hole on the side wall of the soundproof box. The invention effectively solves the problems of noise and heat balance, can significantly reduce the temperature of the engine oil by more than 30°C, and ensures the reliable lubrication of the engine and the power level of the whole machine is consistent with that of the open-shelf product.

Description

technical field [0001] The invention relates to a generator set, in particular to an engine-driven generator set, wherein the engine and the generator are coaxially connected and installed in a sound-proof box together with an air induction casing. Background technique [0002] Generator sets are generally widely used as civil and industrial power sources to meet the power needs of many occasions such as homes, schools, hospitals, and construction sites. However, most of the products currently on the market are open-frame products. Because their engines are directly exposed to the outside, they have the disadvantage of high noise levels, which cannot meet the requirements for quiet workplaces and night work environments. [0003] In order to reduce the noise to the greatest extent, the engine and generator are enclosed by the soundproof box and the number of air inlets and outlets is greatly reduced. Due to the heat radiation generated by the operation of the engine and gene...
