Performance Analysis And Improvement Measures Of Ventilation Cooling System Of Shaoshan 8 Electric Locomotive

Shaoshan 8 electric locomotive is a national key scientific and technological projects during the "Eighth Five", its successful development at the time to fill our empty of fast passenger locomotive.However, in practice, Shaoshan 8 electric locomotive appeared in such problems, particularly as a core part of electric locomotives ventilation system, when it fails, will seriously affect the locomotive driving state, the paper that is for Shaoshan 8 ventilation cooling system electric locomotive that often appear in practice few failures, thorough analysis, and on this basis, suggest improvements, and achieved good results.This total is divided into four parts.The first part makes a concise introduction to ventilation for type SSs locomotive, focusing on the detailed description of the ventilation unit of the air branch;The second part is mainly the computation, stresses in ventilator’s shaping computation, because the process of calculating the pipe network resistance is too complex, and the computed result is not very precise, this article used the experiment to test as well as profits from the former locomotive data to complete ventilator’s shaping, moreover, in this partial contents, there has also made a detailed introduction to the ventilator and its related knowledge; The third part makes a detailed description of the auxiliary circuit and control circuit,which are closely related to ventilation for type SSs locomotive, the auxiliary circuit aspect mainly stresses in introduced how the locomotive did give ventilation power supply, the control circuit aspect mainly introduced fan cooling system various ventilators’ startup procedure; The fourth part is for the SSs locomotive ventilation and cooling system is actually running three typical faults occur, through the analysis of the original circuit troubleshooting reasons, combined with the car and the locomotive pilot operating rules and other methods, put forward reasonable solutions to the problem, used in the scene actually, all the original locomotive overcome failure, and achieved good operating results.In this paper, SSs electric locomotive ventilation and cooling systems as well as various aspects of failure analysis are introduced emphasis on practicality, is built on a long-term SSs electric locomotive actual operating statistics and information, based on a thorough analysis of the conclusions, after further research on a larger reference.
