AIRLOCK
The airlock acts as a seal between the vacuum and
atmosphere sides of the machine and is located at
the bottom of the collector cyclone tank.
As the airlock rotor turns, a pocket is filled with
material when it points upward. As the pocket
rotates, it is moved to the bottom where the material
drops out of the pocket into the discharge pipe.
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 atmosphere
sides.
When checking or maintaining the airlock, follow this
procedure:
1.
Clear the area of bystanders, especially small
children.
2.
Turn machine off, lock out tag out master control
panel and wait for all moving
parts to stop before starting
maintenance work.
3.
Checking Tip Clearance:
a. Use a feeler gauge to check
the clearance between the
tip and the case. Inspect
each tip over its entire width.
b. The clearance of the tips
must be maintained at 0.005
to 0.007 inches at all times.
Adjust or replace tips as
required to insure system
sealing.
c. Replace any tips that are
bent, chipped or broken.
NOTE
Blades are reversible if
not excessively damaged.
