Study On The Type Of He Xie Locomotive’s Repair Class And Repair System

The existing He Xie type communication transmission comotive is set up for:monthly insepection,quarter insepection,halfyear repair,annual repair,two-year insepection,and six-year insepection.The monthly repair and the annual repair are in order to examine the project,it is borne by the locative railway administration（company）;Two-year repair and six-year repair are highlevel repair,the construction is two-year to two-year to six-year checkin,component disassembly test for centralized maintenance.It is necessary to optimize the existing He Xie locomotive repair system.This article through to the He Xie type locomotive operation maintenance quality research,analysis of law and compare locomotive repair class and repair system abroad,the current He Xie system of the locomotive repair class and repair system has the following main problems:the first is underutilized parts quality assurance period.Currently He Xie type locomotive repair cycle and the part of the locomotive parts design exists dislocation of the quality guarantee period,repairs to some locomotive accessories super quality guarantee period,and some of the locomotive repair parts less than the quality guarantee period,caused the locomotive parts accessories,disrepair and excessive maintenance problems in locomotive spare parts quality guarantee period underused.The second is the setting imbalance of locomotive repair and repairing structure.According to the principle of He Xie electric locomotive repairing structure set,advanced maintenance process should include low maintenance process,according to the maintenance manual accessories suppliers,the current"two yearly check-two yearly check-six yearly check"He Xie electric locomotive overhaul repairing structure,some parts according to the requirements of He Xie electric locomotive second annual maintenance update,the following six annual overhaul repairing locomotive according to the scope of maintenance requirements also need to update,locomotive parts accessories two consecutive updates,excess of locomotive parts accessories maintenance repair^[1].The third,the maintenance scope of the biannual repair of the He Xie locomotive is unreasonable.Because of He Xie ac drive locomotive technology introduced without synchronous locomotive maintenance technology,senior He Xie locomotive maintenance procedures in the groping stage,He Xie locomotive second annual repair scope provided by the manufacturing company.To solve the above problems,effectively control the harmonious locomotive maintenance costs,improve the efficiency of locomotive operation maintenance,combining with the characteristics of new type locomotive technology,according to the strategy of"going out",is in line with common international practices,recommend the classification repairing reform project that combine with running kilometer and use of time,which based on running kilometer as main line,to form a harmonious locomotive repair system reform plan,which has been proved to be good in practice.
