The NAVCO BH 3 is a Pneumatic Piston Vibrator designed to provide reliable and effective performance, even when
exposed to sever adverse elements. The size and operating characteristics of the BH 3 make it ideally suitable for solving
medium duty bulk material flow problems.
Operation and Construction
The model BH 3 vibrator incorporates a nominal 3” piston and bore. During operation, compressed air is alternately
directed from one end of the piston to the other through a series of internal ports. The piston is the only moving part, which
makes the pneumatic piston vibrator a reliable, low maintenance device.
The vibrator housing is a one piece, ductile iron
casting. This adds to the durability and reliability of NAVCO Pneumatic Piston Vibrators.
The action of the piston in a pneumatic piston vibrator generates high amplitude vibration with unidirectional or linear force
vectors. High amplitude characteristics enable the vibrating energy to be transmitted in the capacity required to overcome
the strength of the bulk material involved in a bridge (arch) or a rathole (pipe). Other advantages of high amplitude, linear
vibrators include low utility consumption and minimum bin wall stress.
Linear Vibration offers the following advantages:
¾
The work or energy generated by the vibrator can be directed normal or perpendicular to the flow of bulk material to
address a specific material flow problem. The vibrator work is used very efficiently to reduce the sliding friction angle of
the hopper and to overcome the strength of the bulk material in the hopper. These two factors are the key to promoting
the flow of bulk solid materials.
¾
Vibrators that generate linear vibration do not develop high shearing forces at the bin wall. This allows a simple, more
direct approach to mounting these vibrators.
¾
Linear vibration is ideal for driving vibratory feeders and compaction tables.
