Investigation and Solution Measures for Abnormal Conduction Fault of Balance Valve
Based on the abnormal conduction fault of the balance valve used in the Fuxing high-speed train unit,through methods such as fault investigation,ground testing,and flat crystal detection,confirm that the sealing surface of the check valve used for the balance valve is abnormal.Develop experimental research plans for check valves,it is found that the grease resistance test and inadequate mold cleaning can lead to poor sealing of the check valve sealing surface,ground test faults can be replicated.After developing a solution based on the cause of the malfunction,batch balance valves use well,effectively solved abnormal conduction faults.At the same time,it provides research directions for fault resolution solutions for similar products.
