Uphole explosion-proof motors and underground explosion-proof motors are two types of explosion-proof motors with different uses. Purpose: Inoue explosion-proof motors are mainly used in ordinary industrial places to prevent explosions caused by sparks, arcs or high temperatures caused by the motor.
Underground explosion-proof motors are used in dangerous environments such as coal mines and oil wells to prevent sparks generated by the motor from causing explosions of flammable gases. Explosion-proof level: The explosion-proof level of underground explosion-proof motors is generally Exd (d: reaches an explosive environment) or Exe (e: the motor itself does not generate a source of detonation), which is suitable for non-mine hazardous environments; while the explosion-proof level of underground explosion-proof motors is generally Exd ( d: reaches explosive environments), Exde (de: can be used in hazardous environments containing flammable gases) or Exn (n: does not easily cause explosions of combustibles), suitable for mines and other underground workplaces with flammable gas environments.
Structural features: Underground explosion-proof motors usually have more stringent design and manufacturing requirements to adapt to the harsh mine environment, such as dustproof, waterproof, wear-resistant and other characteristics. The above-ground explosion-proof motor is relatively simple and does not need to consider the complex factors of the underground environment.
Generally speaking, underground explosion-proof motors are suitable for general industrial sites, and their design and manufacturing are relatively simple; while underground explosion-proof motors are specifically designed for flammable gas environments such as mines, and have higher explosion-proof levels and stricter requirements. When choosing an explosion-proof motor, users should choose a suitable explosion-proof motor based on the specific application environment and needs.
