Application Scenarios
This product is designed to address the unique needs of large, low-speed rotating equipment requiring high-volume, high-throughput gas flow through the center structure. It is primarily targeted at the following heavy-duty industrial sectors:
1. Chemical and Pharmaceutical Processes
Applications: Rotating agitator shafts in large reactors/mixing tanks, and rotary dryers.
Solution: Nitrogen (N₂) is injected into sealed containers through a hollow shaft core for inert gas protection, pressurization, or purging during the process, preventing material oxidation, or controlling the reaction environment.
2. Metallurgy and Heat Treatment
Applications: Rotating mechanisms for the lid or crucible of large furnaces, and rotating components in continuous annealing lines.
Solution: During heat treatment, nitrogen is introduced to create a protective atmosphere to prevent oxidation of metal materials at high temperatures. The large aperture facilitates the passage of cables for monitoring components such as thermocouples.
3. Heavy Machinery and Large-Scale Testing Equipment
Applications: Rotating spindles in large bearing testing machines, and certain large rotating test platforms for wind turbines. Solving Needs: Providing nitrogen for cooling or sealing rotating parts. The large central aperture is also used for routing hydraulic piping, main cables, and other components, enabling complex functional integration.
4. New Energy and Materials Manufacturing
Applications: Lithium battery sintering furnaces and rotating units in large composite molding equipment.
Solving Needs: Providing a stable, clean inert gas environment during precision manufacturing processes to ensure product quality.
