Problems solved by technology

[0007] If the air compressor does not start, there will be no compressed air in the brake system of the locomotive JZ-7, so that the locomotive will have no braking force, and at the same time, each electric control valve will not be able to operate, which will directly affect the driving safety.

Embodiment Construction

[0026] A method for troubleshooting a locomotive without auxiliary power generation, comprising the following steps:

[0027] Step 1: Count historical fault handling results, and sort fault types according to frequency from high to low;

[0028] Step 2: According to the sorting of fault types in step 1, troubleshoot in sequence.

[0029] Carrying out comprehensive, in-depth and detailed research and analysis on the auxiliary power generation circuit unit, and making statistics on the fault treatment results for many years, the inventor found that the following fault points cause the proportion of locomotives without auxiliary power generation to account for more than 90%. According to the fault point frequency from high to low, they are:

[0030] 1) The auxiliary contact QC1 of the starting contactor is faulty;

[0031] 2) Fix the failure of the auxiliary contact GFC of the power generation contactor;

[0032] 3) Diesel locomotive controller DLC failure;

[0033] 4) The co...

Abstract

The invention discloses a DF10D series locomotive non-auxiliary generating fault processing method. The method comprises the steps of 1, calculating history fault processing results, and ranking the fault types according to frequency from the high to the low; 2, according to the rank of the fault types, troubleshooting the faults in sequence. According to the DF10D series locomotive non-auxiliary generating fault processing method, in actual repair practice, a traditional method is abandoned that a circuit is comprehensively analyzed and detected point-by-point, the fault repair time is shortened, so that the locomotive is put into production rapidly, and company production loss caused by locomotive faults is lowered.

Description

technical field [0001] The invention relates to a method for processing failures of locomotives without auxiliary power generation, in particular to a method for processing failures of DF10D series locomotives without auxiliary power generation, and belongs to the technical field of internal combustion engine maintenance. Background technique [0002] The auxiliary power generation of DF10D series diesel locomotive is an important part of the electrical system. Its stability is related to the safe operation of the whole locomotive. If it fails, it will cause the locomotive to stop running and reduce the operating efficiency. To deal with the auxiliary power generation failure of diesel locomotives, it is necessary to comprehensively analyze the general circuit diagram and check all possible failure points one by one. The locomotive has no auxiliary power generation fault handling method to quickly judge and handle faults and improve maintenance efficiency. [0003] There ar...
