Locomotive cooling system leakage detection system and method

The invention provides a locomotive cooling system leakage detection system and method, and relates to the technical field of internal combustion engine cooling. One end of the exhaust pipeline is connected with the external air source, the control valve, the pressure regulating device and the pressure indicator are sequentially arranged on the exhaust pipeline in the airflow direction, and the other end of the exhaust pipeline is connected to a deflation pipe of a locomotive expansion water tank. The leakage detection method of the locomotive cooling system is implemented by using the system. According to the detection system and method, the pressure maintaining capacity of the cooling water system is verified through a hydraulic pressure test before application of the locomotive cooling water system, potential leakage points of the cooling water system are found, and fault expansion caused by cooling water leakage is prevented. 本发明提供一种机车冷却系统泄露检测系统及方法，其涉及内燃机冷却技术领域。该系统包括外部气源、在一端与外部气源连接的排气管路、以及沿气流方向依次设置在排气管路上的
