YW-K200/E23 Normally-Open Electro-Hydraulic Drum Brake

 

💡 Key Features & Characteristics

Normally-Open (Fail-Safe Open) Operation:

Power-to-Brake: The brake remains in the released (open) position when de-energized. It only applies the braking force when the electro-hydraulic thruster is powered on. This is critical for applications where the default state must be free movement.

Custom Design: This is a special-order product manufactured according to specific user requirements, distinct from standard normally-closed (power-to-release) brakes.

High-Performance Specifications:

Braking Torque: The YW200-E23 model delivers a nominal braking torque suitable for its 200 mm wheel size, typically in the range of 100 - 200 N·m (exact value depends on spring calibration).

Drive Unit: Powered by an Ed23 electro-hydraulic thruster, which provides a thrust force of 230 N.

Reliable & Maintenance-Friendly Design:

Self-Lubricating Bearings: The main hinge points are equipped with self-lubricating bearings, ensuring high transmission efficiency and a long service life without the need for regular lubrication.

Equal Clearance Mechanism: Features an interlocking device that automatically keeps the clearance between the brake shoes and the wheel perfectly even on both sides, preventing one-sided drag or floating.

Easy Maintenance: The brake pads (linings) use a quick-release, clip-on structure. They are available in various materials, including non-asbestos semi-metallic (hard/semi-hard) and soft linings, making replacement fast and convenient.

Intuitive Adjustment: The main brake spring is housed inside a spring tube, and a braking torque scale is provided, allowing for easy reading and precise adjustment of the braking force.

Optional Safety & Control Devices:

Can be equipped with manual release devices, limit switches (for open/closed status), and automatic wear compensation devices (offering up to 5 levels of automatic compensation as the pads wear down).

🏭 Typical Applications

The YW-K200/E23 is specifically designed for applications requiring a normally-open braking logic:

Emergency Braking Systems: Used as a secondary or emergency brake that only engages when a fault is detected or power is intentionally applied to stop the system.

Conveyor Systems: Ideal for belt conveyors where the default state must be free movement, and braking is only required for controlled stops.

Specialty Machinery: Custom industrial equipment where the operational sequence demands a brake that is normally disengaged.

Safety-Critical Applications: Systems where a power failure must result in the brake being released to allow for safe coasting or manual override.

Note: The YW-K200/E23 is a highly specialized safety component. Its normally-open design is critical for specific operational sequences and safety protocols. When installing, ensure the control system is configured to provide power to the thruster only when braking is required, and that the brake's default state aligns with the machinery's safety requirements.
