Subway "physical examinationist": For the safety and coolness of passengers, they war at high temperatures

The continuous high temperature and heat have brought great tests to the operation of the city. When passengers enjoy the convenience brought by the subway and the coolness brought by the air conditioner in the carriage, there are such groups of people who sweat like rain, fight on the front line, fight the heat of the heat, fight the high temperature, and the convenience of the subway operations and the convenience of the large number of passengers. For escorting, they are the maintenancers to ensure the safe operation of rail trains.

At the Xujing base of Line 17 of the Rail Transit, the trains in the garage stopped in turn. Although the sun could not be seen here, it was still very sultry in physical feelings. In order to enable the train air conditioner to run smoothly in high temperature weather, and provide passengers with a cool travel environment, vehicle maintenance personnel need to clean and check the train air conditioners on a regular basis. The huge "baking test". Close to a row of maintenance vehicles, the maintenance personnel wearing blue workers, heads of helmet, and waist -hanging seat belts are working on their waist, open the air conditioning cover, and skillfully filter the dust with dust Take out the net from the air conditioning cover and replace it with a brand new filter. During the work, the maintenance personnel also needed to carefully check the compressors, condensed fans and other equipment and parts of the air -conditioning units to check whether there were abnormal conditions. Such actions are repeated, and their clothes are soaked in sweat, but they have no time to take care of these.

The staff told reporters that due to line reasons, Line 17 trains will frequently switch on the ground and underground, which is also a challenge for air conditioning. Before the departure of the laborer every morning, the maintenance personnel will set the first carriage to a weak cold carriage. At the same time, the No. 17 train uses variable frequency air conditioners to intelligently adjust the temperature of the carriage to ensure that passengers can feel a very balanced temperature regardless of the ground or underground.

A trip to the subway train shuttled in the context of the city and carried each passenger to arrive safely. The details of the work behind the scenes are rarely known, but their adherence has allowed thousands of citizens to enjoy the fast, accurate and efficient of rail transit.
