Component Details

1. Casing

• Structure: Cylindrical type.
• Inside the casing, spark-proof copper rings are arranged around the impeller rotation area to achieve explosion-proof performance.
• Functions: Collects gas, guides gas flow to improve the fan’s internal efficiency, supports the motor, and protects the impeller during operation.

2. Impeller

• Structure: Airfoil-shaped blades.
• Material: ZL104 cast aluminum alloy.
• Undergoes strict dynamic balance calibration and overspeed testing.

3. Stationary Vane Support

• Functions: Connects the motor to the casing.
• The stationary vanes adopt a twisted blade guide vane structure, which collects the gas discharged from the impeller and converts part of its kinetic energy into pressure energy.

4. Marine Explosion-Proof Motor

• Performance: Good moisture resistance, mildew resistance, and salt spray resistance; stable operation and low noise.
• Structure: Enclosed three-phase AC squirrel-cage rotor induction motor. Prevents dust, iron filings, or other debris from entering the motor interior, suitable for harsh marine environments.
• Working Principle: Alternating electric field generates an alternating magnetic field through the coil; changes in magnetic flux generate magnetic force in the rotor winding, driving the rotor to rotate and converting electrical energy into mechanical energy.
• Explosion-Proof Standard: Manufactured as flameproof type in accordance with GB3836.1-2010 Explosive Atmospheres - Part 1: General Requirements for Equipment and GB3836.2-2010 Explosive Atmospheres - Part 2: Equipment Protected by Flameproof Enclosures "d".
• Optional Accessory: Space heater (on request).
• Brand Options:
  • Domestic brands (on request): Dezhou Hengli, Jiangsu Dazhong, Yuandong, etc.
  • Imported brands (on request): ABB, Siemens, Baiwei, etc.
