What are the common faults of rotary joint
Wondering what the common faults of rotary joints are? Main failures include fluid leakage, poor rotation jamming, abnormal noise, pressure drop and seal failure caused by wear, aging and improper installation.
1: Because the concentricity between the hollow shaft of the rotary joint and the rotating body used is not equivalent.
2: The installation machine has low precision and high vibration.
3: Slurry, dirt and other foreign objects enter the contact surface of the friction pair.
4: Use pressure, temperature, speed, etc. beyond the range of optional rotary joints.
5: Failure to add lubricating grease according to the prescribed time, failure to change the lubricating grease during high-temperature use of the rotary joint, abnormal or damaged sound of the ball bearings.
6: The friction surface of the sealing friction pair of the rotary joint is deformed, and the wear of the compensating ring is relatively large.
7: The sealing ring of the rotary joint is deformed, aged, cracked, and stuck.
8: The rupture and damage of corrugated pipes.
