- Power: 10-15 hp, 15-20 hp
Orton has a wide range of Unbalanced vibrator motors to meet the requirement of various industries wherein material handling plays a major role.
These vibrators help to empty, dose, convey, loosen, test, clean, screen, compact, distribute, feed etc., and therefore have a very wide application in Mining, Fertilizer, Chemical, Pharma & Food Industry etc.
These vibrators are suitable for mounting on bin and storage silo, vibrating feeders, tables & screens and many other applications Orton Unbalance Motor Vibrator is totally enclosed, surface cooled units operating 415/440 volts, 3 phase, 50 cycles. A. C. Supply. The vibrating frequency depends on the revolutions of the rotary unit and can be chosen from four ranges available viz., : 3000, 1500, 1000, 750 vibrations per minute. The Centrifugal force can be adjusted from Zero to Maximum by manipulating the relative positions of the eccentric weights provided on either side of the shaft. Various models are available giving a wide choice of Centrifugal force, frequency of vibration, mounting position, Insulation etc. The customer is therefore assured of getting the most suitable vibrator to meet his requirements.
When used as a single unit, they impact circular vibrations. If directional vibrations are needed, two vibrators running in the
opposite direction should be use.
Salient Features- Sturdy and robust construction.
- Totally enclosed dirt & dust proof construction.
- Amplitude of vibration can be controlled.
- Heavy duty cylindrical roller bearings for long and trouble free operation.
- Low noise as compared to Electromagnetic Vibrators.
- Centrifugal Force can be adjusted from zero to Maximum.
- Low maintenance due to absence of belts, pulleys, chains sprockets etc.
Construction :
The motor vibrator motor has removable end shields and of robust design and the made out of graded cast iron. The material for shaft is alloy steel of ample size to transmit the rated vibratory forces. The ball / roller bearings used are heavy duty to give a long trouble free performance. The design of these motors are aimed at obtained MAXIMUM VIBRATIONS WITH MINIMUM POWER.
The protection class is IP 55 {Totally enclosed construction). The windings consist of super enamelled copper wires, slot and phase insulation, varnish etc as specified for F class, as required.
Precautions
In order to be able to choose the proper sense of revolution, not only the force of vibration but also the output of the vibrator has to taken into consideration. The outward temperature of the vibrator must not exceed 80° C. If the temperature becomes higher than 80° C due overload, either the setting for Centrifugal Force should be brought down or a much powerful motor vibrator has to be used. In order to avoid overload, It is necessary to mount a thermal circuit breaker, which can be supplied at extra cost. Since the temperature sensing elements are be embedded in the winding itself, the order for this overload protection has to be given along with the vibrator.
Fixing the motor vibrator The vibrator should be fixed to a well faced plate with high tensile bolts of adequate size and secured tightly by means of nuts and lock washers. These nuts should be tightened for the first time after about four working hours of the vibrator. Further checks are to be made every week.
