According to incomplete statistics, the current total manufacturing explosion-proof electrical production enterprises more than 100, the explosion-proof motor association member unit 77, the vast majority of enterprises not only in the production of explosion-proof electrical products, but also the production of general electrical products, coal mine professional motor manufacturing enterprises accounted for about 15%.

The rapid development of economy the demand for energy growing, making the coal, petroleum, chemical industry business conditions improved significantly. At the same time, the coal, oil, chemical industry on the safety in production and the production efficiency is more and more attention to, the demand of the explosion-proof motor showed a growth trend.

This explosion-proof motor industry mainly user management benefit generally poor, resulting in the explosion-proof motor industry shrinking market demand, industry competition is intense, comprehensive economic efficiency continues to decline, operating pressure increased.

From 22 in survey of the industry enterprise statistics data pooled analysis point of view, in the first half of explosion-proof motor industry enterprises of explosion-proof motor output over the previous year a slight decline over the same period, order quantity and sales were down 13%, 8.7%; a substantial increase in inventories of finished goods; explosion-proof motor product quantity or price of Qi, resulting in explosion-proof motor sales value fell more, due to the decline in production scale and cost, costs continue to increase, resulting in a sharp slowdown in earnings. Industry overall economic operation quality declined year on year.

28.92 million kW in the first half of the industry total output, compared with the same period last year to reduce 261 million KW, decrease of 8.3%; explosion-proof motor output 542 million KW, representing a decrease of 120 million KW, decrease 18.1%; high-pressure explosion-proof motor output 259 million KW, representing a decrease of 45 million kW, 14.9% reduction; low voltage explosion-proof motor output 232 million KW, representing a decrease of 306 million KW, decreased by 24.3%; explosion-proof motor sales 535 million KW, representing a decrease of 137 million KW, down 20.4%; explosion-proof motor cumulative orders of 446 million KW, representing a decrease of 123 million KW, down 21.5%.

On half motor product sales revenue 52.5 billion yuan, representing a decrease of 7.7 billion yuan, reduction of 12.9%; industry enterprise 2015 half explosion-proof motor sales value 5.34 billion yuan, representing a decrease of 7.3 billion yuan, explosion-proof motor industry market performance difference in the motor industry.

At present, China's explosion-proof motor in the annual demand of about 20 million kW or so, the HV explosion-proof motor about 700 million kW or so, accounted for explosion-proof electrical demand in 28%; explosion-proof motor industry market present polarization trend, large motor market concentration degree higher, medium and small-sized motor market concentration degree is low, intense competition. Enterprises lack of R & D capability, product technology content is low, competition ability is poor, in the past two years also enterprises in production or semi shutdown state. Industry enterprises into a shuffle stage.

From the point of view of the statistics of industry products, vibration proof type low-voltage motor production occupied 86% of the explosion-proof motor market, the efficiency of its products with 3-order energy efficiency of GB18613 energy efficiency standards. Comply with the requirements of the current standards. In accordance with the provisions of national energy efficiency standards GB18613, July 2016 motor efficiency indicators to meet the requirements of two energy efficiency.

Currently, explosion-proof motor branch has organization backbone industry completed the development of YBX3 series products, and through the identification of the industry, industries and enterprises is to digest the stage production. When will replace Yb3 series of flame-proof type three-phase asynchronous motor, meet the requirements of energy saving and green environmental protection. Flameproof motor type and coal mine motor industry for the production of various types of coal special motor.

Development period

China's explosion-proof motor industry after decades of practice, from a technical design to production manufacturing process have tended to be mature, especially the technique of design level, has reached the level of similar foreign products, with the ability to develop a variety of explosion-proof motor. Products of the manufacturing process is in continuous progress.

At present, the impact on the performance of China's small and medium-sized motor product level is the main factor of raw materials not stable, especially the differences in the quality of silicon steel sheet greatly. In addition, the technological transformation of motor generally less investment, machining parts and components of general equipment proportion is larger, and the accuracy is not high also affect the quality of the motor is one of the reasons. In addition, the industry as a whole manufacturing technology level and the international advanced level there is still a gap compared. To solve these problems requires not only efforts of explosion-proof motor industry, but also other supporting industry vigorously support.

Due to China's explosion-proof electrical production enterprises pay more and more attention to product quality, strictly the quality pass, explosion-proof electrical product quality and continuously improve the level, effectively promote the coal mine, the safety situation of petroleum chemical industry the rapid improvement in. Its main achievements are, Qunsiqunshang accident substantially reduced, security situation continues to improve.

China Coal Machinery Industry Association president Zhang Yong told reporters: "in recent years, China's explosion-proof motor industry development rapidly, product output continued to expand, the national industrial policy to encourage explosion-proof motor industry to develop in the direction of high technology products, domestic enterprises new investment projects and investment gradually increased. Investors of explosion-proof motor industry attention more and more closely, 'Twelfth Five Year Plan' period of explosion-proof motor industry areas of focus and investment opportunity research become hot issues. Future during the '45' China's explosion-proof motor industry development promising."

He also said that the coal machine industry development mainly to accelerate the "Five Transition": one is to accelerate from a focus on industrial development to advanced manufacturing industry, high-tech industry and modern service industry collaborative development and transformation; the second is from the emphasis on the introduction of capital to pay attention to the introduction of advanced technology, scientific management and high quality talents transformation; the third is from focusing on the expansion of the scale to focus on the promotion of quality and benefit of transformation, the transformation from relying on preferential policies to enhance the comprehensive service functions; the fifth is transformed by the consumption of resources and the environment to environment friendly.

The explosion-proof motor industry towards high power motor tends to be low and miniaturization, efficient motors to replace the ordinary motor, motor module, environmental protection direction, which fits the 45 coal machine development planning, the future development of explosion proof motors very can be expected.
