Improve the efficiency of petrochemical pump

Release date:2015-06-15 16:11 Source:http://www.hotelsuninns.com Views:

Energy saving of petrochemical pump is the core of China energy strategy and policy. According to the introduction of energy efficiency of our country is lower than 10% of advanced countries. Energy consumption per unit of energy consumption is 20% to 80% higher than that of the developed countries, and the weighted average is about 40%. China is one of the highest energy consumption countries in the world.. According to the "five eleven" plan, the next 5 years of our energy consumption per unit GDP to reduce 20%, steel, petroleum, petrochemical, chemical and other 9 key energy consuming industries to carry out energy-saving operation of enterprises. Pump is the national energy saving mechanical and electrical products, the results of many sampling survey show that the power consumption of the pump can be about 20% of the national power generation. In our country, industrial pumps for pump a total of 55% ~ 60%, while the petrochemical pump accounted for one third of industrial pumps, because in recent years the pace of development of the petroleum and petrochemical industry faster, this ratio will be showing rising trend. Therefore, the petrochemical pump is a large energy consumption, energy saving potential is huge. The relevant data show that the actual operating efficiency of domestic petrochemical pump is generally lower than that of the developed countries by 30% ~ 10%. There are two main reasons: first, the efficiency of domestic pump than the industrial developed countries of the same type of product is 5% ~ 10%, two is not the pump selection and pump adjustment unreasonable. Improve the efficiency of the pump itself, the difficulty is great, the price is also great for the majority of users and managers of the pump, but also powerless. All adopt imported high efficiency pump, cost is too high, not reality. There is no need based on the status of domestic pump efficiency is low, improve the efficiency of the pump made in China, this is what we can do and should do. This aspect of energy-saving potential is huge, should arouse our enough attention.

The reasonable choice of pump is the main engine, it and the pipeline and its accessories constitute a system. The operating efficiency of the pump is not only related to the performance of the pump itself, but also with the performance of the whole system.. In order to improve the operation efficiency of the pump, it is necessary to stand on the point of the system, so the matching of each component of the system is the best and the most reasonable, and that is, the maximum of the selection is reasonable..
