Pneumatic Linear Vibrators - NTS Series

Supplier: Vibration Systems & Solutions

Piston model are either non-impacting or impacting models, with the former being preferred for most applications.

In both types, a piston reciprocates inside a cylinder with internal ports giving the back & forth motion without the need for special valve arrangements.

In non-impacting types, a self-generated air cushion eliminates metal-to-metal impact at each end of the piston stroke, reducing noise levels and stress on the hopper wall. Most VSS models of this type are designed as non-impacting units and are not modified impact models. As with the rotary types, regulating the air inlet pressure will change the frequency and force, but the amplitude can also be reduced by throttling the exhaust (effectively increasing the internal air cushion so that the piston doesn't travel the full length of the cylinder).

Pneumatic Linear Vibrators - NTS Series

  • Linear vibration
  • Resistant against aggressive environmental conditions
  • Nominal frequency from 827 min-1 to 9,040 min-1
  • Centrifugal force 32 N to 21,808 N
  • Frequency and amplitude are adjustable separately
  • Synchronous operation possible (NTS 350 and higher)
  • Available in ATEX compliant or in stainless steel

Applications
The pneumatic linear vibratiors series NTS are especially suitable for conveying, compacting and loosening bulk material, due to the completely linear vibration. They are used to empty bins and as drives for conveyor and dosing troughs. A special feature of NTS vibrators is the possibitiy of the synchronous operation of several NTS, when using a coupling kit. Starting from NTS 350 NF to NTS 50/08 this is available as special execution and starting from NTS 50/10 to NTS 20/40 it is a standard.

Design and functioning principle
The vibration is produced by a freely vibrating, self reversing piston. This oscillation supports. expedites or enables a variety of applications. NTS linear vibrators start and stop without delay in any installed position. A built-in pressure spring provides for a reliable start-up at vibrators with aluminium housing. The noise level is below 80 dB(A). Increasing the supply pressure causes an increase in frequency, throttling the exhaust(s) reduces the amplitude.

For operation a control valve is required (not included in scope of delivery). ATEX compliant linear vibrators of the NTS series and units with a stainless steel housing are available.
