The purpose of locomotive fire-free return training is to enable locomotive drivers to master skills related to fire-free return operations to improve their ability to deal with emergencies. No-fire return means that when the locomotive cannot move on its own, it is towed off-site by other locomotives or tractors and returned to the repair site for repair.
The main objectives of fire-free return training are:
1. Improve the driver's emergency handling capabilities: In actual operation, various failures may occur on the locomotive, such as engine failure, brake system failure, etc. prevent the locomotive from running normally. Through fire-free return training, drivers can learn how to properly respond to various breakdown situations to ensure a safe and smooth experience.train location.
2. Familiar with the locomotive fireless return operation process: fireless return operation is a complex task that requires the driver to master a series of return operation processes, including preparation, fault diagnosis , sending contacts and usage. trailers Devices etc. Through hands-on training, drivers can become familiar and master these operational procedures and improve the efficiency and accuracy of return operations.
3. Cultivate Driver Safety Awareness and Adaptability: During the fire-free return process, the driver must communicate and coordinate effectively with other drivers, dispatchers, and other personnel. Practical training can raise driver awareness of collaborative operations, improve adaptability in complex environments, and ensure process safety.s back.
In short, the aim of fire-free locomotive return training is to improve the driver's technical level and emergency response capabilities, to ensure that faulty locomotives can be returned for repair in a timely and orderly manner, and ensure that the safety and smooth operation of trains.
How to handle HXD3C locomotive no-fire return
1 Set the single valve handle to the “running position” and the auto-valve handle to the “reconnection” position.
2. The braking system is off.
3. Turn the fireless loopback socket door of the ERCP module to the “In” position.
4. Close the parking brake door (B40.06) and there should be ventilation.
5. Open the middle pipe cap door.
6. Connect the brake hose, slowly open the gear hose cap door and wait untile the brake pipe pressure reaches a constant pressure.
7. Check that the parking indicator is red and the brake indicator is green, manually release the parking brake unit and confirm that the clamp is loose.
8. (Close the main air cylinder cap door A10) Discharge the air from the main air cylinder and auxiliary air cylinder below 250 kPa (straight ground drain valve).
9. The main locomotive performs braking and emergency operations and confirms that the braking status of the locomotive without fire and the main locomotive are consistent.
