Tips: Rotary union leakage causes and treatment methods
|Cause of Leakage
|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.
