Method for cleaning train pneumatic brake tube system

Abstract

The invention relates to a method for cleaning a train pneumatic brake tube system. The method includes the steps of tube outer wall cleaning, tube inner wall cleaning, air reservoir outer wall cleaning and air reservoir inner wall cleaning. The method is characterized in that construction operations are carried out through a heating cycle cleaning system when tube outer wall cleaning and tube inner wall cleaning are carried out, the heating cycle cleaning system comprises a connection hose, a circulating pump and a heating water tank, and the main steps includes that system leakage detection is carried out, chemical cleaning is carried out, cleaning agents are added to the heating water tank and heated, the circulating pump is started for circulating cleaning, the temperature of cleaning agent solutions keeps between 40-55 DEG C, after chemical cleaning, flushing is carried out through distilled water, the solutions left in the tubes are blown out through compressed air which undergoes two-stage purification processing, the pressure of the compressed air is 0.6-1.0MPa, and finally nitrogen purging is carried out so that the tube system can be sealed after nitrogen purging. By means of the method, the train pneumatic brake tube system can be easily, conveniently and efficiently cleaned, so that the train pneumatic brake tube system can keep clean for a long time, and maintenance of the train pneumatic brake tube system is facilitated.

Description

Technical field [0001] The invention relates to the field of cleaning and maintenance of pipeline systems, in particular to a method for cleaning a train air brake pipeline system. Background technique [0002] The train air brake system consists of an air compressor, an air storage cylinder, a working pipeline, a battery valve and a brake system. The air compressor produces compressed air. The generated compressed air needs to pass through the air storage cylinder to ensure that its working pressure is stable and suitable. Then the compressed air enters the solenoid valve through the working pipeline, and the solenoid valve controls the closing of the brake system through compressed air. Since the solenoid valve is a circuit device, if the compressed air that is passed in contains moisture or oil, it will damage the solenoid valve and cause the train brake to fail. Therefore, it is necessary to clean the working pipeline and the air storage cylinder (hereinafter collectively ...

Problems solved by technology

[0003] The overhaul cycle of trains such as subways, bullet trains, and high-speed rails is about once every ten years. Generally, the train air brake pipeline system is cleaned only during the overhaul. Therefore, the dirt attached to the train air brake pipeline system lasts for a long time. , the cleaning is more difficult, the conventional pipeline cleaning method is difficult to clean the dirt deposited on the train air brake pipeline system and keep the train air brake pipeline system clean for a long time
