BEd121/12 series are flameproof / explosion-protected, fully enclosed oil-immersed electro-hydraulic thrusters, used as safe actuating devices for industrial brakes in hazardous explosive gas or dust environments.
Basic Identification
Model: BEd121/12 Series
Type: Explosion-protected electro-hydraulic thruster / pusher
Protection: Explosion-proof / flameproof structure
Structure: Fully enclosed, oil-immersed wet type
Application: Actuator for electro-hydraulic brakes in hazardous areas
Key Parameters
Rated thrust: 1200 N
Working stroke: 120 mm
Suitable for explosive gas / dust hazardous locations
Working Principle
When energized, the explosion-proof submersible motor drives the impeller to generate hydraulic thrust, extending the push rod to release the brake.When de-energized, hydraulic pressure dissipates; the return spring retracts the push rod, allowing the brake to engage automatically.
