    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.
