Ed50/12 Electro-hydraulic Thruster

 

 

💡 Key Features & Characteristics

Electro-Hydraulic Operation:

Power-to-Raise, Spring/Gravity-to-Lower: When powered on, the built-in motor drives a centrifugal pump impeller. This generates hydraulic pressure that forces oil from the upper chamber to the lower chamber, pushing the piston and pushrod rapidly upward to release a brake or actuate a mechanism. When powered off, the motor stops, and the piston quickly returns to its original position under the force of an external load spring and its own gravity, applying the brake.

Smooth & Reliable: Provides a smooth, shock-free mechanical motion, making it ideal for frequent start-stop operations.

High-Performance Specifications (Ed50/12):

Rated Thrust: Delivers a consistent thrust force of 500 N.

Rated Stroke: Provides a lifting travel of 120 mm.

Power Supply: Operates on a standard industrial 3-phase AC 380V / 50Hz power supply.

Duty Cycle: Capable of continuous operation (S1) or intermittent duty (S2, typically with a 60% load duration rate), with a high maximum operating frequency (up to 2000 cycles/hour for short-stroke variants).

Robust & Maintenance-Friendly Design:

Compact Aluminum Housing: The outer casing is made of cast aluminum alloy, making it lightweight, corrosion-resistant, and aesthetically pleasing.

Non-immersed Motor Structure: The motor is isolated from the hydraulic oil, which improves heat dissipation, ensures excellent thermal stability (typically Class B or F insulation), and extends the motor's lifespan.

High Protection Rating: Features a sealed junction box with a cable gland, achieving an IP55 protection rating against dust and water jets.

Extended Seal Life: The motor shaft and pushrod are surface-hardened with hard chrome plating, which significantly reduces wear and extends the life of the sealing components.

Flexible Installation:

Multi-Directional Mounting: Thanks to a built-in balancing air chamber in the cylinder housing, the Ed50/12 can be installed at virtually any angle from 0 to 180 degrees (vertical, horizontal, or intermediate positions).

Note: Regardless of the installation position, the pushrod itself must not bear any external side loads to ensure optimal performance and longevity.

🏭 Typical Applications

The Ed50/12 is widely used as a core driving component across various heavy industries:

Braking Systems: Primarily used as the release actuator for electro-hydraulic block brakes (such as the YWZ4, YWZ5, YWZ8, and YWZ9 series) and disc brakes.

Industrial Control: Serves as a driving device for industrial valves, sluice gates, clamping mechanisms, and directional摆动 (oscillating) or rotating (<90°) devices.

Key Industries: Essential for machinery in crane and material handling, port logistics, metallurgy, mining, railway engineering, and water conservancy.

Note: The Ed50/12 is a highly standardized industrial component. When installing, ensure the voltage matches your local power grid. If operating in environments colder than -20°C, an optional internal heater should be specified to prevent the hydraulic oil from thickening. Regularly checking the hydraulic oil level and the condition of the external seals will ensure decades of reliable, maintenance-free service.
