Wang Jiming, male, born in May 1972, joined Ningxia Qiyuan Pharmaceutical Co., Ltd. in 2004 as a maintenance electrician in the electrical instrument workshop. Since joining the work, he has been engaged in electrical maintenance work on the front line of maintenance and has been unanimously recognized and praised by leaders and colleagues. In October 2015, he participated in the Yinchuan Maintenance Electrician Skills Competition and won the "third prize". In April 2017, he was named the "Gold Medal Worker" of Yongning County. In October 2018, he participated in the Yinchuan General Electrician Skills Competition and won the "First Prize". On April 28, 2019, he was awarded the title of "Fengcheng Craftsman" by Yinchuan City in 2019.

1. Small reforms and innovations

With the upgrading of the company’s production line equipment, the automation of the company’s equipment is getting higher and higher, which brings great challenges to the electrical maintenance work. For this reason, he studies hard and constantly updates the knowledge structure to adapt to the ever-changing equipment maintenance work. . I remember once, the paste pump of the boiler slime combustion system frequently failed during operation, which brought great hidden dangers to the operation of the boiler and seriously affected the safe operation of the boiler. In the past, the limit switch was replaced every time it was repaired. The fault still appeared for a few days. In order to eliminate the hidden danger, he used his spare time at work to go to the equipment site, carefully observed the equipment operation, and asked the operator, and finally found the root cause of the fault-the improper installation position of the proximity switch of the main cylinder of the paste pump , Resulting in frequent equipment shutdowns, so he made a new detection device by himself, which ran normally after installation and debugging, and the fault was eliminated.

2. Make persistent efforts and improve skills

Wang Jiming is very passionate about work. He bought some professional books at his own expense to recharge himself. Through the accumulation of knowledge, he is more comfortable at work. He used his knowledge and combined with the status quo of field equipment to upgrade the plate and frame filter press in the workshop. The electrical control of the previous filter press was controlled by a relay, with many control elements and complicated circuits, which was time-consuming and laborious to find faults. After modification, programmable controllers were used to make the peripheral circuits simple and clear, and the faults were reduced, which can ensure the operation of the board and frame. Reliable and save maintenance costs.

3. Advance in the face of difficulties and achieve better results

The company’s starch production line with an annual output of 200,000 tons is an old production line with scattered field equipment, long battle lines, many personnel, and equipment operations on site. Various instruments are also scattered on site. There are drawbacks in the connection of the front and back processes, which gives the control of process parameters. It is very inconvenient and has a certain impact on the physical and mental health of the operators. In order to ensure the physical and mental health of employees and improve product quality and economic benefits, in early 2017, after careful organization and overall coordination, the company decided to implement automation transformation for the 200,000 tons of starch production line per year. This transformation breaks through the previous outsourcing model. The company independently designs and develops the control system. This is also an innovation and experiment in the company, which is extremely challenging. Recommended by the leader, Wang Jiming is responsible for the design of the electrical control system schematic diagram and the preparation of the production process automation control system program. For this reason, he goes deep into the production line, is familiar with the entire process of starch production, and communicates extensively with the workshop operators. After discussion, the process control points and control parameters were finally determined, and the starch process design was optimized. When compiling the control system program, he combined the actual situation of the production, and strived to be simple and practical, and used automatic adjustment program control in the key process, so that the temperature, pressure and other parameters in the production process were displayed centrally, which was convenient for the operator to monitor and adjust in real time. The production system runs more smoothly, and the process indicators remain stable. At the same time, the parameter history records can be used to trace the causes of abnormal conditions in order to achieve the purpose of adjusting process control. When designing the electrical schematic diagram, he combined his years of maintenance experience, and strived to control the schematic structure to be reasonable, so as to facilitate future maintenance personnel to read and use. After a year of hard work, he overcame numerous difficulties and finally made the transformation a complete success. This transformation has improved the level of project automation control, realized material, liquid level, flow, concentration visualization, production process valve opening data, operation and operation automation, so that the production rhythm is stable, the product quality is uniform and stable, and noise and Harmful odors harm employees and greatly improve the working environment of employees; Reduced staffing and reduced staff by 20% in the workshop; Reduced the labor intensity of employees and improved work efficiency; By-products are dried, and the exhaust gas temperature of the tube bundle is used to control the opening of the steam valve. Speed, real-time automatic adjustment of steam consumption, saving steam and reducing steam consumption.

"Although the road is not feasible, it is impossible to achieve a small thing," as an ordinary maintenance worker, Wang Jiming does not have superhuman wisdom, but he is unwilling to be mediocre and caring for the enterprise. The spirit of silent dedication realizes his own value in ordinary positions and interprets the beauty of labor. He is our pride and an example for us to learn from.
