一、前言韶山Ⅰ型电力机车自采用JZ—7型空气制动机以来,因管道清洁度差,导致制动系统及各种电空阀故障增多,直接影响了机车运行的安全。为了提高电力机车质量和运行可靠性,八一年工艺科与铆焊车间密切配合,对管道清洁度问题进行了探讨,研制出一种新的制动管道除锈、防锈工艺,经技术鉴定和生产验证表明:管道喷丸除锈、防锈新工艺具有投资少、上马快、操作简便、清洁度好、生产效率高等特点,解决了电力机车空气制动管道清洁度达不到要求的质量关键。
I. INTRODUCTION Since Shaoshan Type Ⅰ electric locomotive has adopted JZ-7 type air brake, the failure of the brake system and various electropneumatic valves has increased due to the poor cleanliness of the pipeline, which has a direct impact on the safety of locomotive operation. In order to improve the quality and operation reliability of electric locomotives, the technology department and the welding workshop closely cooperated in August 2001 to discuss the problems of pipeline cleanliness. A new brake pipe rust and rust prevention technology was developed. After technical appraisal And production verification shows that the pipeline peening and rust-proofing new technology has the advantages of less investment, quick start-up, simple operation, good cleanliness and high production efficiency, and solves the problem that the quality of the air brake pipe of an electric locomotive can not reach the required cleanliness The essential.
