Leaking in the drum dryer
Thread Content
The mechanical seal kept dripping water; it was checked that the seal was shifted outward, and after the hex key became loose, it was pushed back into place using a crowbar and tightened. After water was supplied, it was confirmed that there was no leakage. If there is a leak, the only options are to remove and replace the O-ring and the static ring, as well as adjust the concentricity.
It is recommended to disassemble it for thorough cleaning, and then replace the seal ring. To prevent the metal parts from being damaged.
You can check the O-ring of the motion ring
