All these provide a clear policy direction for the explosion-proof motor manufacturing industry.

I. Industry Overview

Explosion-proof motors are mainly used for machinery supporting power equipment in explosive dangerous places such as coal, petroleum, chemical industry, military industry, aviation, marine engineering, port light industry, textile, heavy industry, medicine and grain processing. Therefore, the development of explosion-proof motors is closely related to the development of these industries. At present, there are about 80 enterprises that manufacture explosion-proof motors nationwide. The vast majority of them are not specialized in producing explosion-proof motors, but also produce other products. According to industry statistics, in 2004, the output of explosion-proof electrical machinery industry in China was 7.181 million kilowatts, the total industrial output value was 6.056 billion yuan, and the profit was 305 million yuan. The number of employees in the industry was about 23,116, including 3,566 engineers and technicians, accounting for the total number of employees. 15.4%.

China's explosion-proof motor industry, the two basic series of motor products is YB2 series flameproof three-phase asynchronous motor and YA2 series increased safety three-phase asynchronous motor. YB series motor replacement product is YB2 series motor, YB series flameproof three-phase asynchronous motor product standard has been abolished, YB2 series flameproof three-phase asynchronous motor will fully replace YB series motor, become the leading product of explosion-proof motor industry.

Judging from the statistics of major economic indicators in recent years, due to the continuous and rapid development of the country’s macroeconomic situation, the overall economic situation of the explosion-proof motor industry is good. The total industrial output value, product output, and profits completed by the industry have been increasing year by year, and the demand in the domestic market is rising. The sales of products have increased significantly. At the same time, the foreign exchange earned through exports has also increased year by year. The amount of losses in the industry has been significantly reduced. However, the development of enterprises in the industry is unbalanced, and some enterprises have poor economic returns. What needs to be clearly pointed out here is that the situation in which the supply of explosion-proof electrical products exceeds demand in the domestic market has not changed fundamentally, but the explosion-proof electrical motor industry continues to grow unabated. With the increase in the manufacturing cost of explosion-proof electrical motors, prices have rebounded. Significantly, but some companies have been deterring prices from seizing the market from time to time. In the case of serious excess production capacity of the explosion-proof motor industry, market competition is fierce. It should be noted that the explosion-proof motor industry has a limited market capacity. If companies want to survive and thrive in fierce market competition, they must conduct investigations and studies to explore market demand trends, take targeted measures, and develop a unique development path. , The use of their own advantages to participate in market competition, in order to make the company invincible, with technological progress, the continuous development of technological innovation, for the explosion-proof motor industry to contribute to the healthy and orderly development.

Second, market demand

The country’s infrastructure and basic industrial construction are booming. In addition to the Yangtze River Three Gorges, the South-to-North Water Transfer Project, the West-East Gas Pipeline, the West-East Power Transmission, and the Qinghai-Tibet Railway, there are a large number of large-scale coal mines, oil fields, open-pit iron mines, power stations, and airports. Key projects such as ports, high-speed railways, and high-efficiency highways, as well as a large number of urban construction and residential construction projects, must be supported by the use of electrical products. The explosion-proof motor industry is an important industry in the electrical appliance industry. Explosion-proof motor products are mainly for the coal industry, petrochemical and other sectors, combined with the development of coal, petrochemical industry can predict the future development trend of the explosion-proof motor industry.

1, the coal industry

Due to the development of the national power industry and the growth of the coal industry, the state has adopted measures such as coal mines to shut down and shut down the coal industry in order to strengthen the implementation of safety production management policies. During the “Eleventh Five-Year Plan” period, China’s coal production will be maintained. In the range of 1 to 2 billion tons, for this reason, explosion-proof motors for the coal industry will be around 300 to 4 million kW/year.

Due to the structural adjustment of the coal industry and the closure and reorganization of small coal mines around the country, the demand for small-capacity explosion-proof motors will decrease.
2. Petrochemical industry

With the development of new-type industrialization in China and the increase in the number of cars, the supply of petroleum is increasing. The development of the offshore oil and natural gas, the development of the West-East Gas Pipeline, and the petrochemical industry, in addition to the construction of the West-East Gas Pipeline In addition to the project, it is reported that during the “11th Five-Year Plan” period, about 5000Km of crude oil high-pressure pipelines will be newly constructed; in addition, the demand for oil refining, ethylene and three synthetic materials (synthetic resin, synthetic rubber, synthetic fiber) will be 6% during this period. The growth rate of ~9% increases. This requires a large number of oil and gas pipeline gathering equipment and large-scale and highly efficient petrochemical equipment, focusing on the development of desert and marine large oil exploration and drilling equipment, long-distance oil and gas gathering and transportation equipment, and an annual output of over 600,000 tons of ethylene, 45 The increase in tons of synthetic ammonia, 800,000 tons of urea and chemical fiber and other large-scale complete sets of equipment, as well as the need to develop high-end petrochemical products to meet the needs of the market, will increase the demand for explosion-proof motors and predict the explosion-proof motors during the “11th Five-Year Plan” period. The annual demand will reach 170-1.8 million kilowatts.
3, other industries

In addition to the above-mentioned types of host industries, such as fertilizers, pharmaceuticals, chemical building materials, metallurgy, underground construction equipment, logistics and transportation equipment, city gas and other industries, the demand for explosion-proof motors will continue to grow. It is expected that During the first five years, the demand will reach 80 to 1 million kilowatts per year.

4, environmental protection equipment

In order to promote the coordinated development of economy, society and environmental protection, the ecological environmental pollution in China has been further controlled, and the level of comprehensive utilization of environmental quality and resources has been further improved. It is learned that the total investment in national ecological construction and environmental protection during the “Eleventh Five-Year Plan” will be greater than The "fifteen" 700 billion yuan. Therefore, environmental protection equipment will continue to develop rapidly, focusing on development; urban sewage treatment and solid waste treatment and comprehensive utilization equipment, urban and industrial noise prevention and control equipment, and air pollution control equipment, road sweeping and snow removal equipment, which is also an explosion-proof motor The industry has opened up new market space.

5. Construction of terminals and oil depots

Over the past few years, international cooperation and the development of offshore oil have strengthened the construction of oil depots in China. This is not only the need for the development of China’s national economic construction, but also a strategic consideration for adapting to the current world situation, and the construction of crude oil terminals, oil depots, pumping stations, and oil pipeline systems. It will be a new growth point for the explosion-proof motor market.
