Description

The High Quality Explosion Proof Drum Brake integrates a heavy-duty, flameproof brake frame with a matched YT1 Series Explosion-Proof Thruster.
• Fail-Safe Operation: Designed with a spring-set, electro-hydraulic release mechanism.
• Energized State: The YT1 actuator activates, its push rod extends rapidly, and the lever mechanism opens the brake lining to release the drum.
• De-energized State: Upon power loss or emergency stop, the thruster push rod retracts instantly under the heavy-duty brake spring force, engaging the brake lining to achieve secure, predictable braking.

 

structure and working principle

 

The BYWZ3 series brake is composed of a brake frame and a matched YT1 series thruster. When energized, the actuator actuates and its push rod extends rapidly, opening the brake lining via lever mechanism; when de-energized, the thruster push rod retracts quickly under the force of the brake spring, engaging the brake lining to achieve braking.

FAQ

 

Q: Which hazardous area standards does it comply with?

A: The brake meets ATEX and IECEx certifications and can be supplied with ISO 9001 quality management compliance. Optional regional certifications like CE/EAC are available upon request.

Q: How is the brake actuated and controlled?

A: It uses a spring-applied, thruster-actuated mechanism. When energized, the YT1 thruster opens the brake lining; when power is cut, the brake engages immediately for fail-safe operation.

Q: Can the brake be customized for specific machinery?

A: Yes. OEM and customization options include torque rating adjustments, mounting configuration, thruster match, and explosion-proof rating to meet your unique industrial application.

Q: What documentation is provided for procurement and compliance?

A: We provide technical datasheets, dimensional drawings, certification copies (ATEX/IECEx/ISO), and testing reports to support purchasing, installation, and regulatory compliance.

Q: How are the brakes packaged and shipped for bulk orders?

A: Industrial export packaging with anti-rust protection is standard. Wooden crates or pallets can be customized based on shipment volume. Lead times are provided for standard and custom models.

Q: How can I ensure compatibility with my existing machinery?

A: Technical consultation is available. We provide CAD drawings, installation support, and thruster matching guidance to ensure seamless integration into your system.
