The CR400AF-A Fuxing EMU can do a third-level maintenance in Chengdu!

On July 18, the Chinese Academy of Railway Sciences officially announced the review results of the three-level maintenance qualification of the CR400AF-A Fuxing EMU, and the review results were qualified. This marks the third-level maintenance qualification of the Chengdu EMU section of 350 kilometers per hour CR400AF-A Fuxing EMU. At this point, Chengdu EMUs have also have the three-level self-maintenance qualifications of CR400AF and CR400AF-A Fuxing EMUs.

The reporter learned that before, the Chengdu vehicle section completed the CR400AF-A-2101 Fuxing EMU 39 days from April 29th to May 7th. Unlike the CR400AF type of eight car groups, the CR400AF-A type is 16 marshals. The "Revoaste" "Fuxing" has increased two power units on the basis of existing technology. The system and other adaptive expansion designs have doubled the maintenance workload. However, compared with the first CR400AF-2140 Fuxing EMU, the maintenance efficiency has been greatly improved.

In this trial work, the Chengdu EMU section takes professional management as the lead. It must be efficient to the production organization and make the top -level design in overall resources. Relying on the experience of the CR400AF EMU autonomous maintenance experience in the early stage, 152 different differences items of the CR400AF type and CR400AF-A type are combed, based on the existing maintenance process, and the three-level repair of the vehicle group "pre-inspection, disassembly, maintenance, installation, verification" In the five stages, technical and data simulation of the entire maintenance process in advance. According to the simulation results, optimize the maintenance quality card control project, combined with the actual situation, timely adjust the production rankings and human resources in a timely manner, and solid Each step is to effectively ensure the smooth development of the first CR400AF-A Fuxing EMU.

At the same time, Chengdu's vehicle section also took the opportunity of this trial repair to conduct research on the autonomous repair of the LPH190A battery storage battery. In June, the LPH190A batteries of the Fuxing EMU were obtained in June. The era of Fuxing "injects the" new engine "into the maintenance cycle and saving maintenance costs in the future.

Next, Chengdu EMU will carry out a three -level repair work of 250 kilometers per hour in the second half of this year. The construction and development of urban economic circles, Sichuan -Chongqing and Guizhou's "colorful ring line" high -speed rail brands can help.
