Description

Technical Field

[0001] The utility model belongs to the technical field of equipment technical transformation, and particularly relates to a diesel generator set. Background Art

[0002] Diesel generator set is a common power generation equipment, which is composed of a diesel engine and a generator. Diesel generator set has the advantages of high efficiency, reliability, flexibility and economy, so it is regarded as a reliable backup power source in many critical occasions.

[0003] In the prior art, a Chinese patent with a reference publication number of CN 210289922 U discloses a diesel generator set, including a base, a diesel engine is provided in the middle of the base, a cooling water tank is provided on the left side of the diesel engine, a generator is connected to the right side of the diesel engine, a start-stop control box is provided on the right side of the generator, and the diesel engine and the generator are connected through a reducer. The utility model can increase the torque through the reducer, and can drive a generator with higher power to generate electricity through the same diesel engine output, which can reduce the volume of the whole machine, facilitate assembly and transportation, reduce the purchase cost of the diesel engine, reduce the production cost, and thus improve the performance of the diesel generator set.

[0004] The comparative document provides a diesel generator set. It is well known that when the temperature of a diesel engine is above 0 degrees, 0# diesel can meet the fuel demand. However, in the cold winter, when the temperature is about to drop below 0 degrees, the diesel will condense or solidify, causing the engine to fail to start. Therefore, -10, -20 or even -35 fuel must be used in winter. However, the price of negative diesel is much higher than 0# diesel, ranging from 1,000 to 1,500 yuan higher per ton. In the northern region of my country, the cold season is relatively long, which will increase the cost of use. However, the diesel generator set in the above patent does not solve the above problem.

[0005] Therefore, a diesel generator set is proposed. Utility Model Content
