DYW500-1600 Explosion Protected Electro-hydraulic Drum Brakes

DYW500-1600 explosion protected Electro-hydraulic drum brakes

DYW500‑1600 is a flameproof (Exd I Mb) heavy‑duty electro‑hydraulic drum brake for explosive hazardous areas (underground coal mines, chemical plants, etc.). It's a fail‑safe, spring‑applied brake, widely used on conveyors, hoists, and mining machinery.

DYW: Explosion‑protected electro‑hydraulic drum brake series

• 500: Brake drum diameter 500 mm
• 1600: Rated braking torque 1600 N·m
• Explosion mark: Exd I Mb (coal mine, GB3836.2 compliant); Exd II CT4 (chemical zone 1/2)
• Matching thruster: BEd121/6 or BEd201/6 explosion‑proof electro‑hydraulic thruster

2. Working Principle

• Power ON: BEd thruster extends, overcomes spring force, releases brake (shoes open from drum).
• Power OFF: Thruster pressure drops, strong brake spring retracts shoes, applies brake (fail‑safe).
• Flameproof design: Enclosed explosion‑proof housing contains internal sparks, preventing ignition of external methane/coal dust or explosive gases.

3. Key Technical Parameters

4. Core Features

1. Dual certification: Mine safety mark + flameproof certificate (GB3836, MT912).
2. High torque & large drum: 1600 N·m / 500 mm drum for heavy conveyors/hoists.
3. Fail‑safe protection: Power loss = immediate brake application; critical for mining safety.
4. Easy maintenance: Snap‑in brake shoes, self‑aligning shoes, self‑lubricating bearings.
5. Interchangeable mounting: Same dimensions as YWZ5/YWZ9 series; easy replacement.

5. Typical Applications

• Underground coal mines: Belt conveyors, winches, crushers, hoists.
• Chemical/petrochemical plants: Explosive gas zones (IIA/IIB/IIC, T1–T4).
• Port & metallurgy: Explosion‑risk material handling equipment.
• Heavy machinery: Large cranes, conveyors, and mining hoists.
