Vibratory UF-Exciter Drives

    Vibratory UF-Exciter Drives

Uni – Exciters are used as vibratory drives for vibrating conveyors, screening machines, scalping and self-discharging shakeouts preferably when very big and therefore very heavy machines have to be driven. The long service life in toughest industrial use confirms the refined design concept of the Ei – Exciters.

Construction and Technical Features:

Ei Uniforce Exciters are robust in construction & have powerful drive.

  • Operation is almost Noiseless & Continuous.
  • Maintenance is minimum & easier.
  • Provides peak performance amidst the most serve conditions.
  • OPERATION OF THE EXCITER: – The drive motor drives the unbalance weights through the Cardon Shaft & connecting joints (coupling piece). The rotating centrifugal weights thus give the exciter machines to cause sinusoid ally pulsating drive force to the Vibratory Machine. The force thus exerted is perpendicular to the surface on which the exciter is (foot) mounted through the flange connection. The forces generated from this direction & deviating are however, compensated within the Gear Housing.
  • The speed of the exciter can either be a fixed speed, reverse speed or it can be controlled by a suitable “Variable Frequency Controlled Drive” with varying speed. Variable Frequency Drive is incorporated if the feed rate of the Vibratory Machine is required to be changed.

Construction and Technical Features

GENERAL:Ei Uniforce Exciters are widely used as the drive of Vibratory Feeders, Screening Machines, Vibratory Shakeouts, Vibrating Conveyors, especially when they are very big in size & for handling the material in big quantum. These drives provide to machines, to work against odd & toughest industrial use thereby the longitivity of machine’s life and service is achieved.

Advantages

  • Uniforce Exciters drives: Two shafts with centrifugal weights are operated in opposite directions via a toothed gear , this action creates linear vibrations. the drive power is generally transmitted via a card an shaft with a standard, stationery motor.
  • Heavy Duty: EMI exciters are primarily use for large and heavy vibration machine. Their long service lives and problem.-free operation , even under the most difficult industrial conditions-testifiers to the EMI technical design.
  • Long service live:Our welded designs, EMI gearbox housing, are manufactured exclusively from high quality MS. The bearing arrangement consist of heavy duty , high quality cylinder roller bearings. The centrifugal weight are also protected by particularly sturdy hoods.
  • Machine observation:Forced mechanical synchronization dispenses with the critical synchronization phase and the associated high loading during starting and stopping . The base machine construction is conservatively designed.
  • Easy maintenance: An oil splash system supplies the gear and the bearing with a constant supply of lubrication. EMI exciter can be operated in any position and are reliable in ambient temperatures of -40C to +100C when the appropriate oil is used.
  • Variable parameters:with the machine off, the oscillation amplitude can be reliably set to the particular requirements by simply adjusting the centrifugal weights. The oscillation frequency can additionally be adjusted via a frequency converter.
  • Drive:A standard hydraulic or 3-phase motor is used as the drive motor. Please note that that the highest admissible speed of the exciter may not be exceeded and that the motor’s starting torque must be 2.5-times that of the nominal torque.
  • Tip:where extremely wide or heavy machine are concerned, several exciter can be operated in series with one drive motor. The starting torque is thereby transmitted from one exciter to the next by coupling shafts.
