Airlock - Walinga Ultra-Vac 6614D Operator's Manual

AIRLOCK

The airlock acts as a seal between the vacuum
and pressure sides of the machine and is located
at the bottom of the receiver tank. As the rotor
turns, a pocket is filled with material when it
points upward. As the pocket rotates, it is moved
to the bottom and is moved into the pressure side
of the system. The grain is picked up by the
stream of pressurized air and moved out the
discharge piping.
Efficient operation of the airlock requires a close
fit between the tips of the rotor and the case to
maintain a seal between vacuum and pressure
sides.
When checking or maintaining the airlock,
follow this procedure:
1. Clear the area of bystanders, especially
small children.
2. Disconnect the hydraulic lines from the
tractor to prevent airlock operation.
