Marine Variable Frequency Explosion-Proof Electric Motors Temperature Categories: T1~T6 Ignition temperature of combustible gases for electrical equipment temperature: T1 >450℃; T2 450℃>T>300℃; T3 300℃>T>200℃; T4 200℃>T>135℃; T5 135℃>T>100℃; T6 100℃>T>85℃. Development With the advancement of technology and production, areas with explosion risks are also increasing. For instance, in the past, edible oil production was done using traditional pressing methods. After the 1970s, China began to introduce foreign solvent extraction processes. However, this process requires the use of chemical solvents containing hexane, which is a flammable and explosive substance. Therefore, solvent extraction workshops have become areas of explosion risk, necessitating the use of explosion-proof electric motors and other explosion-proof electrical products. Similarly, with the rapid development of China's highways and the emergence of batch fuel stations, new markets for explosion-proof electric motors have been created.

Marine Frequency-Conversion Explosion-Proof Electric Motors Classification

1. By motor principle

They are divided into explosion-proof asynchronous motors, explosion-proof synchronous motors, and explosion-proof DC motors, etc.

2. By usage location

Available in explosion-proof electric motors for underground coal mines and for factory use.

3. Divided by explosion-proof principles

Available in explosion-proof motors, increased safety motors, positive pressure motors, non-sparking motors, and dust explosion-proof motors, etc.

4. By matching the main unit

Explosion-proof motors are available for various applications including coal mine conveyor, coal mine winch, rock loader, local fan in coal mines, valve, loud explosion-proof fan, marine, lifting and metallurgical use, and brushless excitation synchronous motors for hydrogenation unit. Additionally, they can be categorized by technical specifications such as rated voltage, efficiency, etc., like high-voltage explosion-proof motors, high-efficiency explosion-proof motors, high-slip ratio explosion-proof motors, and high-starting torque explosion-proof motors.

Marine Variable Frequency Explosion-Proof Electric Motor

1. Development of 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 coal mining areas have an installed capacity over 1500kW, and their driving motor power is up to 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 criteria, and the performance of the matching control switches of domestic double-speed mining motors are all somewhat behind the international level.

4. Enhance the reliability of mining electrical motors: The operating conditions for explosion-proof motors in mines are poor, with frequent high-load startups, significant load changes, voltage fluctuations, high environmental temperatures, and some degree of corrosiveness, all of which 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 mining motors.

Marine variable-frequency explosion-proof motors are a type of motor that can be used in flammable and explosive environments without producing sparks during operation. These explosion-proof motors 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 major power source, explosion-proof motors are commonly used to drive pumps, fans, compressors, and other conveying machinery.
