Rotary Union Installation Diagram
Tips: Rotary union leakage causes and treatment methods
Cause of Leakage | Treatment Method |
The concentricity of the hollow shaft with the rotating body is not enough. | Check size and accuracy of the slip ring and adjust the fixed connection to the rotating body. |
The accuracy of the fitting machine is low (large end face coincidence, radial, axial clearance), large vibration. | Find the reason and repair the fitting equipment. |
Foreign matter such as slurry and dirt enter the friction pair contact surface. | Add a filter or decontamination device and modify the type of rotary union. |
The pressure, temperature, speed, etc. used exceed the rated range of the selected rotary union. | Analyze the operating conditions, contact rotary union manufacturers, and change the type of rotary union. |
