Generator set driven by engine

Abstract

The invention discloses a generator set driven by an engine. The generator set comprises a sound proof box, an engine, a generator and an exhaust muffler, wherein the sound proof box is composed of an upper cover, side walls and a chassis; the engine is arranged on the chassis, and an engine cooling fan is arranged at the side inlet of the engine and guides cooling air into the engine; a cooling fan is arranged at the connection part of the generator and the engine to guide the cooling air into the generator; the exhaust muffler is arranged at the rear side of the generator and parallel to the axis of the generator; one end of the exhaust muffler is connected with the engine through an exhaust pipe; a hot air exhaust chamber is further arranged in the sound proof box, is composed of a side panel, a cover plate and an engine speed regulation base, and encircles an engine cylinder end, a cylinder body and one part of the exhaust pipe; an opening is formed in the rear side of the hot air exhaust chamber and is connected with a first ventilation hole at the side wall of the sound proof box. According to the generator set, the problems of noise and heat balance can be effectively solved, and the oil temperature of the engine can be obviously reduced beyond 30 degrees centigrade, thereby ensuring that reliable lubrication of the engine and the power level of the complete generator bring into correspondence with open-shelf products.

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...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the defects of the prior art and provide a generator set, which effectively solves the problems of noise and heat balance, and can significantly reduce the temperature of the engine oil by more than 30°C, thereby ensuring reliable lubrication and overall maintenance of the engine. The machine power level is consistent with that of open-shelf products, and can run stably for a long time
