Rotor middle seals
Rotor circumferential seals
Rotor circumferential seal
The rubber seals are nonwearing and can be easily adjusted by shifting.
The circumferential seals are held by spring clamps that are further secured by an additional spring steel sheet. The rubber seal is pushed gently up against the rotor with a screwdriver. The circumferential seal is pushed back slightly by the rotating rotor, thereby bringing it into optimal operational position.
Middle seal Z-plate
The middle seals are fastened to the middle seal Z-plate. The Z-plates feature slotted holes and are screwed to the middle spar of the rotor casing.
The setting of the Z-plates is done by loosening of the fastening screws and lightly adjusting within the slotted holes.
The middle seals should be pushed as close as possible to the rotor, but they should never scrape against the rotor surface.
The illustration shows an installation example with purge sector. The purge sector is adjusted just like the seal Z-plates. It is important to note the mounting situation (marking on the encasing) during the mounting of the rinse chamber.
