[0002] The main function of the side sliding door of the Sifang platform EMU is to ensure the safety of passengers getting on and off the train and to ensure the air tightness of the train when running at high speed. For the side sliding door of the EMU, which is a key component, the repair is combined with the first-level repair, the second-level repair, the door repair (spring and autumn repair), and troubleshooting. The advanced repair is combined with the third-level repair, the fourth-level repair, the fifth-level repair, and troubleshooting. The new factory repair requires the measurement of various dimensions of the side sliding door, and the door fine-tuning project is carried out in conjunction with the repair group to ensure that the various dimensional data of the side sliding door meet the relevant technical standards, improve the quality of EMU door maintenance, and ensure the safety of EMU operation.
