In recent years, with the rapid development of China's economy, the demand for explosion-proof motors in the petrochemical and coal industries has also increased, which has also promoted the development of China's explosion-proof motor industry. The total number of explosion-proof motor enterprises is growing.
The motor industry is a traditional industry and a basic industry of the national economy. Explosion-proof motors are special motors used in the development of China's coal and petrochemical industries in the early 1970s. They are used in the above industries, such as fans, pumps and compressors. The main power equipment in the machine tool.
In recent years, with the rapid development of China's economy, the demand for explosion-proof motors in the petrochemical and coal industries has also increased, which has also promoted the development of China's explosion-proof motor industry. The total number of explosion-proof motor enterprises is growing. According to incomplete statistics, there are currently more than 100 explosion-proof motor manufacturing enterprises and 77 member units of explosion-proof motor associations. Most of them not only produce explosion-proof motor products, but also produce ordinary motor products. Coal mine professional motor manufacturers account for 15 %about.
The rapidly growing economy has an increasing demand for energy, which has led to a marked improvement in the operating conditions of the coal, petroleum and chemical industries. At the same time, the coal, petroleum and chemical industries are paying more and more attention to safety production and production efficiency, and the demand for explosion-proof motors is increasing.
In 2016, the main users of the explosion-proof motor industry generally had poor operating results, which led to a shrinking market demand for the entire explosion-proof motor industry. The industry was fiercely competitive, the overall economic benefits continued to decline, and operating pressures increased.
According to the statistical analysis of the industry statistics of 22 participating enterprises, the output of explosion-proof motors in the first half of the year decreased slightly compared with the same period of last year. The order quantity and sales volume decreased by 13% and 8.7% respectively; the inventory of finished products increased significantly; The volume and price fell, resulting in a decline in the sales value of explosion-proof motor sales; due to the decline in the scale of production and sales, while the cost and cost continued to increase, the profit fell sharply. The overall operational quality of the industry economy declined year-on-year.
In the first half of the year, the total output of the industry was 28.92 million kW, a decrease of 2.61 million kW, a decrease of 8.3% compared with the same period of last year; the output of explosion-proof motors was 5.42 million kW, a decrease of 1.2 million kW, a decrease of 18.1%; the output of high-voltage explosion-proof motors was 2.59 million kW, a year-on-year decrease. 450,000 kW, down 14.9%; low-voltage explosion-proof motor output was 2.32 million kW, down 560,000 kW, a decrease of 24.3%; explosion-proof motor sales of 5.35 million kW, down 1.37 million kW, down 20.4%; explosion-proof motor cumulative order 4.46 million kW , a year-on-year decrease of 1.23 million kW, down 21.5%. In the first half of the year, the sales revenue of motor products was 5.25 billion yuan, a year-on-year decrease of 770 million yuan, a decrease of 12.9%. The sales value of explosion-proof motors in the first half of 2015 was 5.34 billion yuan, a year-on-year decrease of 730 million yuan. The market performance of the explosion-proof motor industry was worse than that of the motor industry.
At present, the annual demand for explosion-proof motors in China is about 20 million kW, of which about 7 million kW is high-voltage explosion-proof motors, accounting for 28% of the annual demand for explosion-proof motors. The explosion-proof motor industry market is polarized, and the large-scale motor market is concentrated. The degree is high, the concentration of small and medium-sized motors is low, and competition is fierce. Enterprises lack research and development capabilities, low technical content and poor competitiveness. In the past two years, enterprises have been in production or semi-discontinued. Industry companies enter a stage of shuffling.
In 2016, China's explosion-proof motor industry research report shows that from the industry product statistics, the output of flameproof low-voltage motors accounts for 86% of the entire explosion-proof motor market, and the efficiency of its products meets the energy efficiency of Class 3 of GB18613. Meet the requirements of current standards. According to the national energy efficiency standard GB18613, the efficiency index of the motor in July 2016 must meet the requirements of level 2 energy efficiency.
At present, the explosion-proof motor branch has organized the backbone of the industry to complete the development of YBX3 series products, and through industry identification, industry companies are digesting the production stage. The YB3 series flameproof three-phase asynchronous motor will be replaced at that time to meet the environmental protection requirements of energy saving and emission reduction. Among the explosion-proof motors, there are also various coal mine-specific motors produced by the coal mine motor industry.
After decades of production practice, China's explosion-proof motor industry has matured from technical design to manufacturing, especially at the level of technical design, which has reached the level of similar foreign products and has the ability to develop various explosion-proof motors. The manufacturing process of the products is also constantly improving.
At present, the main factor affecting the level of China's small and medium-sized motor products is the unstable performance of raw materials, especially the quality of silicon steel sheets. In addition, the motor technology transformation is generally less invested, the proportion of general equipment for parts processing is large, and the precision is not high, which is one of the reasons that affect the quality of the motor. In addition, there is still a gap between the overall manufacturing process level of the industry and the advanced level of foreign countries. To solve the above problems, not only the efforts of the explosion-proof motor industry, but also the support of other supporting industries. As China's explosion-proof electrical appliance manufacturers pay more and more attention to product quality, strict quality control, the quality level of explosion-proof electrical appliances continues to improve, effectively driving the rapid improvement of the safety situation of coal mines and petrochemical industries. The main result is that the group death and group accidents have been greatly reduced, and the security situation continues to develop in a good direction.
