🛠️ Product Overview: BEd301/12 Explosion-Protected Thruster
The BEd series is a variant of the standard electro-hydraulic thruster, modified with a robust flameproof enclosure to prevent internal sparks or heat from igniting the surrounding atmosphere.
Model Number: BEd301/12
Type: Explosion-Protected / Flameproof / Electro-Hydraulic Thruster
Action: Push (Extend) on Power On.
When powered, the motor drives a pump to extend the piston rod.
When power is cut, a spring returns the rod to its original position.
Key Feature: Safety Certification. Designed to contain any internal explosion and prevent it from igniting the external environment.
📋 Key Technical Specifications

| Insulation Class | F Class (Standard) |
| Power Supply | AC 380V / 660V (3-Phase, 50Hz) |
| Protection Level | IP55 / IP54 (Dust protected & sealed) |
| Work Cycle | S1 (Continuous) or S3 (Intermittent) |
✨ Key Features
Explosion-Proof Enclosure: The motor and electrical components are housed in a robust, flameproof casing (typically steel or cast iron) that can withstand an internal explosion and prevent hot gases from escaping.
Non-Oil-Immersed Motor: The electric motor is sealed and does not sit in the hydraulic oil. This prevents oil degradation and protects the motor windings.
Low Noise & Smooth Operation: Operates with less noise and smoother motion compared to electromagnetic actuators.
Multi-Angle Installation: Can be installed at various angles (0° to 180°), depending on the specific model variant.
🏭 Typical Applications
The BEd301/12 is primarily used in high-risk industrial environments:
Mining Industry: Especially in coal mines (non-excavation faces) for belt conveyors and hoists.
Chemical Plants: Where flammable chemicals or vapors are present.
Port Machinery: For handling bulk materials that generate combustible dust.
Grain Silos: To prevent dust explosions.
💡 Operational & Maintenance Tips
Cable Glands: Ensure the cable entry points are properly sealed to maintain the explosion-proof integrity. Never modify the housing.
Oil Level: Regularly check the hydraulic oil level. Use specified oils like DB-25 or YH-10 suitable for the operating temperature.
Heating Option: In sub-zero environments (< -20°C), install a heating element to prevent oil from gelling.
Inspection: Regularly inspect the piston rod coating for damage, as scratches can compromise the seals and allow hazardous substances to enter.
