YPZ2 Electric Hydraulic Disc Brake

The YPZ2 Electric Hydraulic Disc Brake is a sophisticated braking system that adheres to both German DIN15435 standards and, for certain models, the JB/T7020-2006 standard. This system is designed to provide reliable and efficient braking solutions across various industrial applications. Here, I will break down the advantages, applications, working principles, and usage instructions of the YPZ2 brake, incorporating specific details from the attached files.

Advantages

1. Compliance and Standards: The YPZ2 I, II, and III models comply with the German DIN15435 standard, while the IV, V, and VI models comply with both the DIN15435 and JB/T7020-2006 standards, ensuring high-quality performance and safety.
2. Uniform Clearance Device: The I, II, and III models feature an equal clearance device that maintains equal distances between the brake pads on both sides during use. The IV, V, and VI models include an interlock equal clearance device, preventing one-side brake pad floating issues and ensuring consistent braking performance.
3. Self-Lubricating Bearings: All major pivot points are equipped with self-lubricating bearings, resulting in high transmission efficiency and long service life without the need for additional lubrication.
4. Adjustable Brake Torque: These brakes come with a brake torque scale, allowing for direct display and easy adjustment of braking force.
5. Asbestos-Free Brake Pads: The brakes use asbestos-free pads, which are inserted for easy and quick replacement.
6. Automatic Wear Compensation: The brake pads have an automatic wear compensation device to maintain constant clearance and braking torque over time.
7. Additional Functionalities: Optional features include manual release, release and closure limit switches, and wear limit switches for precise control and feedback.
8. Delayed Closure: The Ed series actuator supports delayed closure for smoother braking.

Applications

YPZ2 brakes are ideal for environments requiring robust and reliable braking systems, such as:

• Industrial machinery
• Hoisting equipment
• Cranes
• Conveyor systems

These brakes are particularly suitable for use in environments with a temperature range of -20°C to 50°C, provided they are free from flammable, explosive, and corrosive gases, and where the relative humidity does not exceed 90%.

Working Principles

The YPZ2 brake operates using an electric hydraulic actuator, typically from the Ed series, such as the Ed23/5 or Ed30/5 models, depending on the required braking force and application. The actuator converts electrical energy into hydraulic pressure that engages the brake pads onto the disc, providing the necessary braking force. The delay valve in the actuator allows for controlled closing, ensuring smooth operation.

Usage Instructions

1. Installation: Ensure the brake is installed in a clean environment free of corrosive substances. The mounting surface must be level and sturdy to support the brake’s weight and operational forces.
2. Operational Setup: Connect the brake to a suitable 380V, 50Hz three-phase AC power supply, or specify alternative power needs at the time of ordering. Ensure that the actuator is properly lubricated with YH-10 aviation hydraulic oil if operating at temperatures below -20°C.
3. Adjustments: Use the brake torque scale to adjust the braking force as needed. Ensure that the clearance between the brake pads is uniform to maintain optimal performance.
4. Maintenance: Regularly check the wear of the brake pads and utilize the automatic wear compensation feature to adjust for any discrepancies. Replace pads promptly when they reach their wear limit.
5. Additional Features: Utilize the manual release and limit switches for enhanced control and safety monitoring. In outdoor or corrosive environments, opt for corrosion-resistant models to prolong the brake’s lifespan.
