"Da Wen Ren" at the plateau tuyere

At 3 o'clock on April 1, at 3300 meters above sea level, the Harbin comprehensive workshop of Xining locomotive depot was very cold, and the cold wind mixed with snowflakes roared by. Feng Xiaojun, dressed in thick clothes and holding a flashlight, walked from the duty room to the locomotive preparation yard and started another round of warming work for five diesel locomotives. Due to the low outdoor temperature, the diesel locomotive must be started to keep warm and prevent the cooling water system of the diesel locomotive from freezing. Once the cooling water system of diesel locomotive freezes and freezes, it will cause locomotive failure and unable to run on line. Therefore, it is very important and hard to warm the diesel locomotive. Khargai comprehensive workshop is located in Gangcha County, Haibei Tibetan Autonomous Prefecture, Qinghai Province. It is windy for most half of the year. Due to the long winter time in the plateau area, it is necessary to warm the locomotive for 9 months every year. The temperature of more than 20 degrees below zero made Feng Xiaojun shiver. He quickly boarded Dongfeng 8b0018 locomotive and skillfully operated it. With a roar, the locomotive started. A few minutes later, he pushed the locomotive's control handle up slightly, and let the diesel engine rotate at 600 rpm. It needs a strong sense of responsibility and dedication to hit the temperature of diesel locomotive. It is necessary to strictly implement the work system of 2-hour patrol inspection. At the same time, it is necessary to grasp the rotational speed of diesel engine. If the rotational speed is low, it can not play the effect of hit the temperature, and if the rotational speed is high, it wastes fuel. After the normal operation of the locomotive diesel engine, Feng Xiaojun began to check the interior and running parts of the locomotive carefully according to the working process. By the light of the flashlight, he bent down, repeatedly screwed the drain valve of the brake air cylinder, and measured the temperature of the brake air cylinder with the thermometer in his hand. "At this temperature, if there is no water flowing out after the drain valve is opened, it means that the brake air pipe of the locomotive works well; if there is water, it must be drained, otherwise the brake system may freeze." Feng Xiaojun said earnestly. Ten minutes later, he finished the locomotive warming up and boarded another locomotive to start warming up. Twenty six workers of Harbin Ergai comprehensive workshop of Xining locomotive depot have been stuck here all the year round, undertaking the daily servicing, maintenance and heating work of locomotives in this area. They set the temperature every 3 hours in winter and every 2 hours at night. They also need to check the main parts of the locomotive and do a good job in preventing the locomotive from slipping. "With novel coronavirus pneumonia wildly beating gongs and drums, the major enterprises are going to work hard to get back to work and the number of locomotives on the line is increasing. We need to ensure that every locomotive can run safely and safely at any time." Feng Xiaojun said as he inspected the locomotive. After a while, he had fallen a thick layer of snow.
