Here's a clear breakdown:
1. Explosion-proof design features
Explosion-proof motors & control systems
All electrical components (motor, switches, control box) are certified to prevent sparks from igniting flammable gases or dust.
Sealed enclosures
Electrical and mechanical parts are housed in flame-proof enclosures with tight seals.
Anti-static materials
Hoses, cables, and machine covers reduce static buildup.
Overheat & overload protection
Temperature sensors and automatic shutdown if the motor overheats.
2. Where it's used
Coal mine roadway lining
Oil and gas facility reinforcement
Chemical plant structures
Underground tunnels with methane or coal dust presence
3. Advantages
Safer operation in hazardous environments
Reduces need for extra external protective housings
Meets local explosion-proof certification standards (ATEX, IECEx, MA certificate in China)
4. Example specifications
Output: 20–40 m³/h (depending on model)
Spray range: 10–15 m horizontal, 8–12 m vertical
Explosion-proof motor: 37–55 kW
Control voltage: Low-voltage, safe control circuit (24 V or 36 V)
