Dwyer BPV - Manual (Page 2)

INSTALLATION
Vibration force transmits more efficiently in a conical hopper tank as
opposed to a rectangular hopper. It is recommended that you install two
vibrators in rectangular hoppers.
1. Vibrator force can be transmitted more efficiently by using “U” shape
steel supports. It can help materials run smoother in the tank or pipe. It
also reduces tank damage accidents.
2. To avoid tank wall amplitude caused by the vibrator moving in a left or
right direction, use “U” shape steel.
3. Reinforced board is required between “U” shape steel and a thin tank
wall.
4. To increase vibration fields in a big hopper tank, criss-cross “U” shape
steel.
Attention: Vibration has to be fixed by a high tension bolt, washer, and
spring washer. Connect with a security cable if the vibrator is installed
onto a hopper.
Notes: Various tanks are based on application requirement. Customers
choose appropriate vibrator types to meet with various applicant demand
(tank shape, material, applied material, etc). Suitable vibrators will not
only prevent obstruction problems but won’t damage the tank walls.
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 BPV Pneumatic Ball Vibrator, no
routine maintenance is required. A periodic check of the system
calibration is recommended. The Series BPV 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.
