This fog gun sprinkler is responsible for the company's traffic road cleaning and mine transportation road dust suppression work. During the operation, it suddenly broke down-the dashboard engine alarm light flashed, the oil pressure continued to be low, and the vehicle immediately stopped. Faced with this sudden "roadblock", everyone pinched a sweat, because this is not only a vehicle stop, but also directly related to the normal operation of limestone transportation production line, and this fog gun truck equipped with Dongfeng Cummins ISB21050 series engine belongs to a new type of EFI diesel engine, with complex structure and lack of maintenance experience. The blind area of technology has become the biggest problem in front of us. At the
critical moment, there is such a figure standing out, he is Wu Jing. In line with the principle of "resolutely not affecting production", he volunteered. If there is no way out, pressure will be turned into power. In order to accurately lock the root cause of the fault, Wu Jing incarnated as an "emergency physician", first checked the electronic control harness interface one by one according to the engine circuit diagram, checked whether there were problems such as loosening, short circuit and virtual connection, and eliminated the hidden dangers of the circuit fault one by one; Then, with the help of professional testing equipment, the engine fault code is retrieved, combined with the working principle of EFI model, the data parameters are analyzed one by one, and any abnormal value is not missed. Low oil pressure is the core crux, he also led the team to disassemble the oil pipeline, check the working condition of the oil pump, check the oil level and viscosity, from the oil circuit to the mechanical parts, disassemble and check one by one, and repeatedly compare and verify.
identifying the "focus", Wu Jing immediately formulated a maintenance plan, accurately replaced the fault sensor, reorganized and adjusted the electronic control line, and repeatedly tested the signal transmission and oil pressure value. After hours of intensive repairs, when the engine restarted, the dashboard alarm lights went out, the oil pressure returned to normal, and the vehicle ran smoothly, the hearts of all the people on the scene finally fell to the ground.
In this emergency repair, Wu Jing led the team to break through from zero and overcome difficulties, not only to eliminate the fault at the first time, but also to let the fog gun sprinkler quickly return to the post of dust suppression and road clearing, to ensure the continuous and stable operation of the limestone transportation production line, and to understand the key points of the maintenance of Dongfeng Cummins new EFI engine through actual combat exploration. It has accumulated valuable experience in the maintenance of new equipment for the team, and has built a solid line of defense for production support with hard work and research. After overcoming
this difficulty, some colleagues will jokingly say that Wu Jing is a master of "blind cultivation", but jokes aside, in fact, we all know very well that behind the success of "blind cultivation", it is not accidental luck, but from more than ten years of "hard work".

Behind the "gold medal" is the "gold" sign written by sweat. It does not belong to the past, but to the future; it is not only a personal honor, but also a clarion call to inspire every struggler around.
