Explosion proof motor industry development potential
Motor industry is a traditional, but also the basic industry of the national economy. In the early 21st century, 70 years, in order to meet the development of the development of China's coal, petrochemical industry and development of special motor, explosion-proof motor is used in the industry of the wind machine, water pump, compressor, machine tool main power equipment.
In recent years, with the rapid development of China's economy, demand for explosion-proof motor in petroleum chemical industry, coal industry is becoming bigger and bigger also contributes to the development of explosion-proof motor industry of our country, the explosion-proof motor, the total number of enterprises in the growth.
Rapid growth of the economy's growing demand for energy, making coal, oil, chemical industry operating conditions significantly improved. At the same time, coal, oil and chemical industry is more and more attention to the safety production and production efficiency, the demand for explosion-proof motor is also more and more big.
From the industry point of view, the output of the explosion proof motor market occupies 86% of the whole explosion-proof motor market, the efficiency of the product is in accordance with the GB18613 energy efficiency standard of 3 energy efficiency. Meet the requirements of current standards. In accordance with the provisions of the national energy efficiency standards GB18613, July 2016 motor efficiency indicators to meet the requirements of 2 energy efficiency.
There are many types of explosion-proof motor, which are usually used in explosion proof, positive pressure type, increasing safety and non spark type.
1. Flameproof and positive pressure explosion-proof motor due to the complexity of the structure, the price much higher than ordinary motor more than doubled, and maintenance requirements for a higher technical level and management level, so in addition to outside the zone 1 hazardous environment applications and other dangerous environment should be or do not have to minimize the use of this kind of motor.
2 increase in safety explosion-proof motor due to the design temperature rise than the general motor, in addition to the motor of the relay protection also has a more stringent requirements, so in general, do not use this type of motor.
3. No spark explosion-proof motor structure and general motors of roughly the same, but in shell protection grade and junction box structure require a higher also in the manufacturing process also increases the reliability measures, so the reliability is high, its price in the various types of explosion-proof electric machine lowest, only than the ordinary type motor slightly higher in maintenance also with the common motor simple, and can be widely used in zone 2 dangerous environment.
Last year, the main users of explosion-proof motor industry operating efficiency is generally poor, leading to the entire explosion-proof motor industry market demand, industry competition is fierce, the overall economic benefits continue to decline, operating pressure increased.
At present, the main factors that affect the level of small and medium-sized electrical products in our country, the performance of raw materials is not stable, especially the quality of silicon steel sheet is very different. In addition, the general investment of motor technology is less, the proportion of general equipment is larger, and the precision is not high is also one of the reasons that affect the quality of the motor. In addition, the industry's overall manufacturing process level compared with foreign advanced level there is still a gap. To solve the above problems not only needs the efforts of explosion-proof motor industry, but also need other supporting industries to 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. The main result is that deaths and injuries is greatly reduced, the security situation continues to improve the direction of development.
