Discussion on the development of the pipeline of the air compressor repairing operation of Shanxi Science and Technology Locomotive Yuan Qing (Taiyuan Railway Section of Daqin Railway Co., Ltd., Taiyuan, Shanxi 030003, China) The development plan, design principle and development process of the assembly line are described. 1 Development of the locomotive air compressor maintenance work line background The rapid development of the railway system leaps and bounds led to the rapid pace and high efficiency development of the railway machine. Maintenance is the basis of each locomotive section. The new operation management mode, new technology, application of new technology and new equipment are launched. The locomotive maintenance standards and process standards have been improved, and the quality of locomotive maintenance has been greatly improved. The safety and reliability of the locomotive ensure the safety of railway transportation. The maintenance work mainly focuses on locomotives. The wind source system focuses on system services such as locomotive brakes and air lines, providing sufficient and reliable high-quality compressed air. Among them, locomotive air compressors play an important role in air compressors. The maintenance, protection, use and management of the equipment are based on the fine inspection and repair. It has become an important topic in my current section to establish a complete set of reasonable locomotive air compressor maintenance operation system and give full play to the overall management concept of maintenance work. 2 In the investigation and argumentation stage, after doing a lot of preliminary preparation work and full investigation and demonstration, we have determined the project plan, that is, developed and developed the Taiyuan Locomotive Depot of Daqin Railway Co., Ltd. (hereinafter referred to as the “locomotive compressor†Maintenance operation line". However, before developing and developing the "locomotive compressor maintenance operation line", we must first understand and analyze the current situation and shortcomings of the air compressor maintenance work in my section. At present, my main electric locomotive is 195 units of 8G and SS1. The three models of locomotive air compressors are 243VC78, NPT-5 and some BT-2.6/10A type overhead screw air compressors, totaling more than 350 units. More than 200 vehicles are released each year, and the average monthly departure is more than 10 units. It takes 2~3 working days for each major air compressor. The shortcomings in the air compressor maintenance work mainly include the following aspects: the working space is narrow, and the air compressor complete maintenance work is divided into several items or even dozens. Items, and most of the operations can not be parallel, can only be completed item by item, batch by batch. Continuously generate repeated operations, infinitely increase labor intensity and labor time, inefficient inspection, and form a malignant The second is that the cleaning and cleaning operation takes time and effort. Before the air compressor is disassembled, it must be thoroughly cleaned and cleaned. The method used in my section is to send the air compressor to an open space more than 500 meters away from the working room. Concentrated high-pressure purging and cleaning, and then pulled back to the workplace for manual dismantling and disassembly and repair. As a result, most of the working time is wasted in the loading and unloading wiping, the work effect is poor, and the work efficiency is low. The third is the cleaning and drying process. Too simplistic. The process of cleaning and drying of Spare Parts after disintegration is too simplified, especially for long, large and irregular fittings, such as radiators and side collectors. Due to equipment and site limitations, the maintenance process is simplified. Fourth, the air compressor oil pump does not have the conditions for individual performance test. The air compressor oil pump performance test is the first in the oil pump maintenance project: Chen Yidong, male, born in July 1982, graduated from the China University of Mining and Technology in 2006, assistant engineer , Dushanping Mine, Xishan Coal and Electricity Group, Taiyuan City, Shanxi Province, 0302.
