In both types, a piston reciprocates inside a cylinder with internal ports giving the back & forth motion without the need for special valve arrangements.
Impacting models have metal-to-metal contact at each end of the piston stroke, which can be noisy and increas stress on the hopper wall. Continuous impact models are also available with a small air cushion to limit the noise to some degree but this also limits the force output. These models can be adjusted for frequency but by their nature cannot be adjusted for amplitude.
Single impact models use a piston held against a spring by air pressure. On release of this pressure the spring impacts against a strike plate.
Pneumatic Piston Vibrators - P Series
- Linear vibration
- Nominal frequency 1350 min -1 to 5650 min -1
- Force output 323 N to 4758 N
- Cast iron body
- Frequency and force adjustable by air pressure
P series are ideal for moving damp and sticky material from hoppers and down chutes. They are also used for knocking concrete products from moulds.
A precision steel piston is moved by air pressure back and forth in a cast iron cylinder. The standard 'S' model impacts into a integral base plate; the 'Q' model has an air cushion to eliminate metal-to-metal contact and give quieter operation.
Operating Conditions Drive medium:
