Shanghai Pingshen Explosion-Proof Electric Motor Co., Ltd. is a large-scale enterprise engaged in the design, research and development, manufacturing, and service of electric motors and motor control products.

Explosion-proof motors are electric motors designed for use in flammable and explosive environments, as they do not produce sparks during operation. They are primarily used in industries such as coal mining, oil and gas, petrochemicals, and the chemical industry. Additionally, they are widely employed in sectors like textiles, metallurgy, urban gas supply, transportation, grain and oil processing, papermaking, and more. As a key power source, explosion-proof motors are commonly used to drive pumps, fans, compressors, and other transmission machinery.

Explosion-proof electric motors for petrochemical systems

1. There will be an increasing demand for explosion-proof and flameless motors. Users of petrochemical systems have recognized the necessity of developing China's explosion-proof and flameless motors through practical use.

2. The reliability of explosion-proof motors is increasingly being focused on by petrochemical system users. As petrochemical enterprises develop towards larger-scale facilities and continuous operation, they require systems to run for extended periods without or with minimal maintenance. Therefore, explosion-proof motors have become the key equipment to ensure these requirements.

3. Explosion-proof and variable-frequency speed control motors have become an urgent demand for energy-saving products among petrochemical users. The energy-saving aspects of explosion-proof motors include: 1) developing explosion-proof motor products, and 2) extensively developing various types of explosion-proof variable-speed motors, particularly designing motors with variable-speed capabilities for fans, pumps, and compressors, which have significant potential for energy savings.

4. New requirements brought by the development of coastal petrochemical enterprises. A series of refineries will be built along the coastal areas of our country, all of which require imports. These imports have high sulfur content and severe corrosiveness, thus necessitating explosion-proof motors with improved corrosion resistance. Additionally, all imports are by sea, requiring explosion-proof motors with high-head large oil pumps for the storage tanks.

5. The significant development of China's western oil industry requires the development of explosion-proof electric motors suitable for desert dry and hot environments. The market demand for medium to large capacity brushless excitation synchronous motors for hydrogenation units will grow annually.

Explosion-proof motors are primarily used in coal mines, oil and gas industries, petrochemicals, and the chemical industry. Additionally, they are widely employed in sectors such as textiles, metallurgy, urban gas, transportation, grain and oil processing, papermaking, and more.

The explosion-proof motor's rated voltage, rated current, power, and speed are the same as those of a standard motor. The difference is that the explosion-proof motor features an additional explosion-proof symbol: Ex.

Mine-used explosion-proof motor

1. Develop high-power motors: The installed capacity of coal mining machines worldwide has exceeded 1200kW, with their driving motor power reaching 600kW; the corresponding scraper conveyors in mining areas have an installed capacity over 1500kW, and their driving motor power has reached 725kW. In China, the driving motor power of coal mining machines is 400kW, and the driving motor power of scraper conveyors is 315kW.

2. Develop mining motors for 3.3kV, 6kV, and 10kV voltage levels: This is due to the extension of mining areas after the widespread adoption of comprehensive mechanized coal mining equipment, which leads to voltage drop, and the use of high-power motors also requires an increase in voltage levels.

3. Development of Double-Speed Mining Motors: To meet the requirements of low-speed start and high-speed operation for coal mine conveyors, foreign mining scraper conveyors are all driven by double-speed motors. The power range, performance indicators, and performance of the matching control switches of domestic double-speed mining motors are all somewhat behind international standards.

4. Enhance the reliability of mine-use electric motors: The operating conditions for explosion-proof motors in mines are poor, with frequent heavy-load startups, significant load changes, voltage fluctuations, high environmental temperatures, and certain corrosiveness. These factors all affect the motor's reliability and lifespan.

5. Accelerate the upgrading and replacement of explosion-proof electric motors for mining use.

6. Standardize the specifications for explosion-proof electric motors used in mining.
