90 , joined the big family of Yunnan Jianfeng after graduating from junior college in 2016 . under the influence of years of Jianfeng culture and the catalysis of the technological progress of various technological equipment in Yunnan Jianfeng, he faded from the youth who had just left the school gate and gradually grew from an ordinary electrician to the technical backbone of the new generation of Yunnan Jianfeng.

As an electrical technician in the production line, for many years, Liu Xiaojian has not only conscientiously completed the tasks related to mechanical and electrical work, but also been responsible for the electrical parts of various technological transformation projects. In his spare time, he worked hard to learn electrical knowledge, constantly improved his skills, actively participated in various training and textual research, started from his own major, and made great efforts to expand all kinds of knowledge outside his major, and achieved good results in all aspects. it has been affirmed by department leaders and colleagues. In the six years since he entered the peak of Yunnan, he has obtained a variety of vocational skills certificates, such as special equipment safety management certificate and nuclear radiation safety certificate, through his own continuous learning. While obtaining relevant certificates, he has also expanded the depth and breadth of his knowledge and improved his skill level.

, he also participated in the training of energy managers and successfully obtained the certificate. He constantly met challenges in new fields, continuously acquired new knowledge and enriched himself. 2021

, Yunnan peak investment and construction of raw meal roller press terminal grinding renovation project was successfully put into use. During the renovation, Liu Xiaojian, as the electrical person in charge of the technical renovation project, and Party B's electrical installation personnel worked overtime to catch up with the progress, from the installation of the control cabinet in the power room, the wiring of the power cord and control line, the installation of the on-site control cabinet and button box, and the wiring of the on-site equipment and control box. A lot of things, he has not been touched before, especially in the process of electrical equipment installation drawings, at the beginning, the drawings and on-site equipment can not be well matched. Through communication and study with Party B's electrical installation personnel, he will soon be able to read the drawings skillfully and know the installation requirements, installation location and control principle of the on-site equipment. During the renovation process, the high-voltage control cabinets of the three high-voltage motors were not included in the project design. The control lines of the original high-voltage cabinets needed to be optimized and adjusted according to the control requirements. After consulting a large number of drawings and actively consulting other electrical professionals, Liu Xiaojian completed the adjustment and connection of the control lines of the high-voltage cabinets on time. During the test run, the high-voltage motor was started by the water resistance cabinet and could not be started for a while. He actively consulted the technicians inside and outside the factory to find out the problem. After adjusting the water resistance cabinet program, the motor was started smoothly. In this technical transformation project, Liu Xiaojian paid a lot, but also made it grow rapidly and gained a lot of application skills and disposal methods. In order to further improve the system, in his spare time, he also searched and sorted out relevant knowledge videos on the Internet for his own weak places and the application of new equipment, and combined with the physical objects on the spot to learn, which greatly improved the learning effect and applied it to work.

In addition to the raw meal roller press project, Liu Xiaojian is also responsible for the installation and debugging of the high temperature gas analyzer in the smoke chamber at the end of the kiln, providing a pair of eyes for the operation of the kiln system. By recording the real-time changes of gas composition data such as carbon monoxide, nitrogen oxide and oxygen content, it provides strong data support for the process operation of the rotary kiln system and greatly improves the research and judgment capability.

cement packaging machine equipment is aging, with many faults and many ash spots on the equipment body. As the electrical director of the system, he participated in the upgrading and renovation of

and 3 cement packaging machines, and was responsible for the installation and debugging of the electrical control system. After the transformation, the effective operation rate of the packaging machine has been significantly improved, and all the ash spots have been solved, which greatly improves the on-site operating environment and work efficiency. 2021 , multiple magnetic levitation blowers were put into use in Yunnan Jianfeng. Compared with the old Roots blower, the new magnetic levitation blower has greatly improved its energy-saving effect and noise treatment. Compared with Roots blower, the energy-saving 20%-25% is saved, and the noise is as low as 80 decibels. During the renovation, Liu Xiaojian was responsible for communication and coordination with the factory personnel, and participated in the installation, commissioning, equipment operation, post-maintenance and other training and learning of new equipment. The original air compressor had low efficiency, many equipment failures and unstable equipment operation, which had a great impact on the normal production of Yunnan peak. Therefore,

and 5# air compressors were upgraded. He installed, debugged and trained the equipment operation under the guidance of the manufacturer's personnel. The modified air compressor is stable in operation and can automatically adjust the operating frequency according to the air pressure. Compared with the original air compressor, the power consumption can be reduced by about 15% . In addition to the above technical renovation work, due to the lack of tracking of hidden dangers of equipment, the inability to trace inspection records and other reasons, there are many electrical equipment failures. Liu Xiaojian has re-compiled the equipment inspection contents and requirements after consulting relevant materials, soliciting the opinions of leaders and predecessors and according to the actual operation of on-site equipment, thus improving the quality of equipment inspection and ensuring the smooth and reliable operation of equipment, great progress has also been made in terms of management.

With its own desire for technology and the company's full trust and support, the new generation of Yunnan Peak employees represented by Liu Xiaojian has grown rapidly. At the same time, it has also witnessed the achievements of Yunnan Peak in technological transformation and promoted the virtuous circle development of Yunnan Peak. (Song Xiaofei)
