APV-C SERIES

APV-I SERIES

NOTES:
Various tanks are based on application requirement. Customers choose
appropriate vibrator types to meet with various application demands
(tank shape, material, applied material, etc). Suitable vibrators will not
only prevent obstruction problems but won’t damage the tank walls.

Large amplitude and low frequency piston types fit in granule with small
S.G. applied material. It is recommended to use multiple vibrators in
serious clog situations or large tank surroundings.

According to various clog situations, required vibrations and suitable
install positions (usually 1/2 L or 1/3 L) are shown above.

VIBRATION FORCE CALCULATION

Taking the accumulated situation into consideration, the appropriate
vibrator will give 0.2~0.5 G accelerated vibration onto the target object.

F=0.2-0.4GW

F: Vibration force (N)
G: Acceleration of gravity
W: Material weight (KG)

MATERIAL WEIGHT CALCULATION

Generally speaking, the hopper portion of the tank should be taken into
consideration.

MAINTENANCE
Upon final installation of the Series APV Piston Vibrator, no routine main-
tenance is required. A periodic check of the system calibration is recom-
mended. The Series APV is not field serviceable and should be returned
if repair is needed (field repair should not be attempted and may void
warranty). Be sure to include a brief description of the problem plus any
relevant application notes. Contact customer service to receive a return
good authorization number before shipping.
