Study on Quick Check Solution for Causes for Brake Sticking Fault of Air Brake System of Railway Wagon
To solve the problem of difficult checking of causes for brake sticking fault of air brake system in the on-site operation of railway wagons,the article is based on the actuality of on-site operation of railway wagons,according to the characteristics and working principles of air brake system,mainly analyzes the action law of the internal key components of pressure limiting valve and sensor valve of the KZW-A automatic empty/load adjusting device in braking and release processes as well as the airflow direction of all branches of the system,summarizes a quick checking method without excessive dependence on the complex braking principle and adapted to the on-site operators,and transforms the checking of brake sticking fault of air brake system from principle deduction to practical and visualized operation so that the checking procedure is simple and practical with strong operability.There is a clear standard for the fault judgement and the requirement for professional skill of on-site operators is not high,so it's easy to be generalized.This solution has got good effect in actual operation on the site and achieved the objective of quickly handling the air brake sticking fault,better ensuring a smooth railway transportation to some extent and improving the efficiency of transportation.With the support of this solution,a checking simulation platform for causes of air brake sticking fault has been built up to lay a solid foundation for teaching,drilling and data research.
