ED50/12Ex Explosion-Protected Electro-Hydraulic Thruster

 

 

💡 Key Features & Characteristics

Explosion-Proof Design:

Hazardous Area Rated: The "Ex" designation means the motor and junction box feature a flameproof enclosure. It is designed to contain any internal explosion and prevent it from igniting the surrounding atmosphere, making it safe for use in mining, chemical plants, and other high-risk zones.

Safety Compliance: Built to meet strict safety standards for hazardous environments, ensuring reliable operation without sparking risks.

Integrated Electro-Hydraulic Mechanism:

Smooth Operation: When energized, the motor drives an impeller to generate hydraulic pressure, pushing the piston rod upward smoothly and quietly. When power is cut, the rod retracts via gravity or the return spring of the connected brake.

Performance: Delivers a precise thrust of 500 N with a long stroke of 120 mm, suitable for medium-sized drum brakes or industrial valves.

Robust & Durable Construction:

Material: Features a lightweight, corrosion-resistant die-cast aluminum alloy housing.

Protection: The motor typically features Class F insulation and an IP55 protection rating, making it resistant to dust and water ingress.

Surface Treatment: The piston rod and motor shaft are usually hard chrome-plated to resist wear and corrosion in harsh conditions.

Versatile Installation:

Mounting Flexibility: The thruster can be installed at any angle from 0° to 180° (vertical, horizontal, or inclined).

Adjustability: The fixed seat and pushrod connection block can often be rotated (typically 90°), providing excellent flexibility for fitting into tight or complex machinery layouts.

Maintenance-Free Operation:

The unit is filled with high-quality hydraulic oil at the factory and features a double-seal structure to prevent leaks, requiring minimal maintenance under normal operating conditions.

🏭 Typical Applications

The ED50/12Ex is essential for safety-critical machinery in hazardous industries:

Mining: Driving brakes on underground belt conveyors, hoists, and winches.

Metallurgy & Steel: Operating heavy-duty brakes and dampers in steel mills where gas leaks are a risk.

Chemical & Petrochemical: Controlling valves and gates in refineries and chemical processing plants.

Port & Harbor: Used on cranes and material handling equipment exposed to explosive dust or fumes.
