Domestic Motor System Will Break The Barrier Of Energy Conservation

- Oct 12, 2018-

Recently, the State Council issued the "Twelfth Five-Year Comprehensive Work Plan for Energy Conservation and Emission Reduction" (Guo Fa [2011] No. 26, hereinafter referred to as the "Program"), proposed 50 policy measures, and determined the chemical oxygen demand in the 12th and 5th regions. The total amount of ammonia, nitrogen dioxide, sulfur oxides and nitrogen oxides are controlled.

The 12th Five-Year Plan outlines that the national energy consumption intensity and carbon dioxide emission intensity are reduced by 16% and 17%, and this standard is also included in the planning as a binding indicator. As the motor industry of the basic kinetic energy industry, its task of energy conservation and emission reduction is quite significant. With the introduction of relevant national subsidy policies, the high-efficiency motor market is gradually favored by the industry, but only by the development and application of high-efficiency motors. Can we achieve the energy saving and emission reduction effect we expected? What we need is a significant reduction in all emissions from processes in the entire motor production chain. Energy-intensive metal raw materials are the most basic constituent elements of motor production. The sharp increase in demand will inevitably bring huge energy consumption. According to data released by the National Development and Reform Commission, in April, the added value of industrial enterprises above designated size increased by 13.4% year-on-year. Among the high-energy-consuming products, the output of steel and non-ferrous metals has steadily increased, and the electricity consumption of these industries has risen sharply.

The energy consumption of China's steel and non-ferrous metals industry is mainly concentrated in the three major areas of mining, smelting and processing. At present, the average energy consumption per ton of metal is still compared with the international advanced level. From the perspective of different products, the average electricity consumption of domestic electrolytic aluminum is 2% higher than the international level; the average energy consumption of copper flash furnace smelting is 20% higher than the international level; the average energy consumption of zinc smelting in kiln closed blast furnace is 33.4% higher than the international advanced level; The average energy consumption of smelting is 84.2% higher than the international advanced level. According to the National Bureau of Statistics, in 2006, the domestic electrolytic aluminum DC consumption was 13506 kWh per ton, the comprehensive energy consumption of alumina was 0.894 tons of standard coal per ton, and the copper flash furnace smelting The average energy consumption is 0.606 tons of standard coal, and the average power consumption of crude copper is 823 kWh per ton. In addition to the high energy consumption of the raw materials of the products, domestic motors also have some problems in technology upgrades, and these problems lead to serious energy consumption in the operation of the motor: the energy-saving control technology of the motor system is backward, and the system operation efficiency is low. Unreasonable system matching, serious horse-drawn car phenomenon, long-term low-load operation of the equipment; motor system control to meet the process requirements as the sole target, the system adjustment mode is backward, most fans, pumps use mechanical throttling adjustment, system operating efficiency low.

China's motor system energy efficiency detection technology, system energy-saving emission reduction overall solution and energy-saving control technology, load matching matching motor and special control device matching integration technology, energy-saving effect and cost-effective to achieve the best matching system energy-saving technology, etc., basic Still in the blank.
