Reducing cost and increasing efficiency are the internal needs of companies to improve resource competitiveness, improve anti-risk ability and achieve high-quality development. Hebei Xinda Group units in-depth implementation of the overall deployment of "cost reduction and efficiency" work, the establishment of cost reduction and efficiency leading group, the "cost reduction and efficiency" as a key work. At the grass-roots front-line posts, we deeply practice accounting management, "make a big deal" in the aspects of deep digging, repairing old benefits and waste, energy saving and consumption reduction, and efficiency improvement, and implement "cost reduction and efficiency improvement" into all aspects of the work.

"Reduce production costs, improve efficiency, start from me, start from their own positions, start from the slightest bit, start from the small things." This is the oxygen plant (Hebei Rongxin) all the staff often on the lips of a sentence. Under the leadership of the factory leadership, the oxygen plant does not depend on the initiative to act, reduce costs carefully, do everything possible to increase benefits, adhere to the independent implementation, repair old benefits and waste, job innovation, etc., and race against time to write a "extreme cost reduction" big article.

The research team of the oxygen general plant found that the nitrogen output of the unit accounted for 38% of the total nitrogen, the annual average operation time was 360 days, and the maintenance could not be effectively arranged, and the nitrogen was sometimes dispersed, because the unit had no small equipment, resulting in a waste of electric energy and increasing the purchase of electricity. In order to reduce the energy waste of the overall nitrogen system and save the mono-oxygen power consumption, Deputy factory director Wang Wanzhong led the team to analyze the reasons, investigate the current situation, and formulate measures to reduce the power consumption to 0.7558kwh/m³.

The research team, starting from the actual situation and solving the problem, analyzes the factors affecting high power consumption from five aspects: man, machine, material, method and environment one by one, and determines the defects of measuring tools through on-site inspection and data comparison. Errors in individual readings, high exhaust pressure of the unit, unregulated compression system, high energy consumption of the equipment, high delivery pressure, increased usage, low level of personnel operation, and no preparation of operation instructions are eight suspicious factors.

In view of these eight suspicious factors, the research team analyzed the main causes one by one, and finally determined the three main reasons. After discussion and countermeasure optimization, the team members formulated specific improvement measures. In view of the high exhaust pressure of the unit, the way to reduce nitrogen delivery by stopping the operation of the piston nitrogen press in time when the pressure rises effectively reduces the unit pressure, reduces the unit oxygen power consumption and saves energy.

In view of the problem of unregulated compression system, according to the amount of nitrogen, run the third-stage nitrogen permeator and nitrogen press, and stop the fifth-stage nitrogen permeator at the same time. In the case of unstable changes in the output, the monitor informs the operator to stop the piston nitrogen compressor in time to reduce the compressed energy. This can not only meet the use of nitrogen, but also achieve the purpose of effective regulation, according to the team's calculation, the use of this method can effectively save 800KW of compressed distribution energy.

For the problem of high energy consumption of the equipment, according to the amount of nitrogen, run the third phase of low-power nitrogen, compress the fifth phase of nitrogen, and stop the fifth phase of high-power nitrogen, and control the compression power within 5400kw, so that the operating power can be reduced by 800KW per hour, greatly reducing the compressed energy.

After the implementation of various measures, the team members counted the pressure of the spherical tank and compressed electric energy, and found that the mono-oxygen power consumption was reduced to 0.7486kwh/m³ under the condition of satisfying the user's use, and it was estimated that the annual benefit was about 3.478700 yuan.

Open source and reduce expenditure every cent, reduce costs and increase efficiency every bit. The group's companies have effectively placed cost control in the "bull 's-eye" position, started from the optimization of production technology, strengthened the repair of old benefits and waste and other details, continued to carry out "micro innovation", and effectively wrote a big article of "reducing cost and increasing efficiency". Reducing costs and increasing efficiency is the mission of responsibility. The majority of cadres and employees should continue to explore potential and increase efficiency according to the deployment of reducing costs and increasing efficiency, give full play to their own wisdom and ownership, sort out "reducing costs" and excavating "efficiency points", strive to be pioneers in improving quality and efficiency, experts in tackling indicators, and models for improving efficiency, and form a vivid situation of "everyone rowing a big ship". Help the company win the battle to reduce costs and increase efficiency!
