Body Sections
1. What Are Hydraulic Rotary Unions and How Do They Work?
Define hydraulic rotary unions as components that enable leak-proof fluid transfer between stationary and rotating parts of machinery.
Describe the main components:
Rotor: Transfers the fluid.
Seals: Prevent leaks.
Housing: Encases the union and provides structural integrity.
Explain the working principle:
Highlight how the rotor moves with the rotating part while maintaining the seal’s integrity to allow uninterrupted fluid transfer.
2. Types of Hydraulic Rotary Unions
Categorize hydraulic rotary unions based on pressure, speed, and media:
Pressure-Based: Low-pressure vs. high-pressure unions.
Speed-Based: Low-speed unions for precise applications (e.g., robotics), high-speed unions for turbines or drilling rigs.
Media-Based: Designed for specific fluids, like oil, air, water, or chemicals.
Include examples of typical industries or applications for each type to demonstrate real-world relevance.
3. Factors to Consider When Choosing a Hydraulic Rotary Union
1. Application Requirements
Match the union’s rotational speed and pressure limits to the machinery’s specifications.
2. Material Compatibility
Recommend materials like stainless steel for high-corrosion environments (e.g., marine equipment).
3. Seal Technologies
Discuss seals designed for extended durability and resistance to wear.
4. Maintenance and After-Sales Support
Stress the importance of choosing unions with efficient designs that minimize downtime.
Evaluate manufacturers based on customer service and technical support availability.
4. Maintenance and Troubleshooting Tips
