Description
Pneumatic linear vibrators of the series NTK generate directed oscillations or vibration movements. These vibrators are used to empty bunkers, to drive conveyor troughs, screens and vibrating tables, inter alia, generally to loosen, convey, compact and separate bulk materials and to reduce friction.
The vibration is generated by a freely oscillating, self-reversing piston. Both masses, on one hand the piston with the oscillating weight and on the other the housing with the attached mass, are thereby counter-oscillating with the ratio of the total weights. If a higher oscillation amplitude of the vibrating mass is required, the piston is simply fitted with a bigger oscillating weight. In order to keep the weight of the mass subjected to vibration at a low level, it is also possible (on units with steel housings) to fasten the mass to the piston. In this case the housing will freely oscillate, if necessary with an additional oscillating weight.
Pressurized air is always applied to chamber A, while pressurized air in chamber B is alternately applied and discharged through the pilot bores in the piston. Since the pressurized area B is twice the size of the area A, the piston is forced outwards or in the direction of the lid respectively. When the pressure air in chamber B is exhausted the procedure is reversed. As the piston is reversed before it reaches the end stop, the only audible noise is caused by the exhausted air, which is reduced by the silencer.
The drive energy is compressed air or nitrogen with a pressure of 1 - 6 bar.
NTK vibrators may also be used for food processing applications and in explosive and wet environments.
Furthermore the frequency can be infinitely varied by means of pressure regulators or nozzles in the air supply line and the amplitude can be adjusted by installation of nozzles in the air discharge line.
The effective working moment and the amplitude can be increased by the attachment of weights to the piston or the housing. This will, however, reduce the frequency.
Depending on the type (with silencer) and an air pressure of 6 bar the noise level is 78-80 dB(A), even less at lower air pressure.
The units NTK 8 AL, NTK 15 X, NTK 18 AL, NTK 25 AL and NTK 40 AL can be operated lubrication free.
