6.1 Observe and check during operation
Check the following during operation:

Check for centric arrangement of the rotor with reference to the roller cog. The radial deflection at the
rear area of the housing must not exceed the values in chapter 5.2 (Admissible concentricity tolerance).
Place a dial gauge from the idle machine frame onto the rotary joint housing to check.

Check the quality of the medium in the system and record the values.

Check for visible leaks at the relief connection of the rotary joint. The operating behavior of the rotating
mechanical seal installed does not change suddenly. If the seal is beginning to fail, this is indicated by
slowly increasing leakage. Regular checks allow you to acquire values concerning the operating behav-
ior of the rotary joint installed in the system.
6.2 Troubleshooting

Leakage at the hous-
ing via the relief holes Rotating mechanical seal is
damaged or worn. Install a new rotating mechanical seal. Check the quality of
the medium and the bearings.
