Problems solved by technology

[0003] For large diesel generators, it is difficult for the traditional starting system to guarantee its starting performance under low temperature conditions. Therefore, auxiliary starting systems such as air starting are needed. Impurities such as oil, water, etc. can easily enter the unit through the air starting system, damage the solenoid valve and other components, and affect the normal start and operation of the generator set

Abstract

The invention discloses a high-power diesel generator compressed air starting system which comprises a black-start small generator set, an air compressor, an air storage pot and a pressure adjusting valve. The black-start small generator set is used for supplying power to the air compressor. The air compressor is communicated with the air storage pot. The pressure adjusting valve is arranged at the rear end of the air storage pot and connected with a pneumatic motor through a pipeline. An oil-water separator is connected between the air compressor and the air storage pot. A Y-shaped filter is arranged at the rear end of the pressure adjusting valve. According to the high-power diesel generator compressed air starting system, the starting performance of a diesel generator under the lower temperature is ensured, the compressed air cleanliness is high, impurities are prevented from entering the generator set, system stability is good, and running is safe.

Description

technical field [0001] The invention relates to an auxiliary starting system for a diesel generator, in particular to a compressed air starting system for a high-power diesel generator. Background technique [0002] Diesel generator is a device that uses a diesel engine to drive a generator to generate electric energy. It has the advantages of quick start, less investment, and convenient operation and maintenance. It is widely used in communications, mining, road construction, forest areas, farmland irrigation, field construction and other fields. [0003] For large diesel generators, it is difficult for the traditional starting system to guarantee its starting performance under low temperature conditions. Therefore, auxiliary starting systems such as air starting are needed. Impurities such as oil, water, etc. can easily enter the unit through the air starting system, damage the solenoid valve and other components, and affect the normal start and operation of the generator ...
