Cause two: The machine is equipped with low accuracy (end face straightness, radial direction, large axial clearance), and large vibration. Disposal countermeasures: find out the reason, repair and install the equipment.
Cause three: Foreign matter such as slurry and dirt enters the contact surface of the friction pair. Disposal countermeasures: add a filter or a decontaminator, and change the type of the rotary joint.
Cause four: The use of pressure, temperature, speed, etc. exceeds the range of the optional rotary joint. Disposal countermeasures: Study the operating conditions, ask the research unit or manufacturer, and change the type of rotary joint.
