Electromagnetic vibrating feeder adjustment Debugging
Electromagnetic vibrating feeder adjustment, debugging mainly electromagnet core gap adjustment, dual particle spring plate connected group of adjustment, debugging.
An electromagnet core and the air gap between the armature tuning
Electromagnetic vibrating feeder air gap between the core and the armature directly affects the size of the normal operation of the feeder, such as improper adjustment of the light so that the current increase, the amplitude decreases and can not operate normally, severe collisions will produce core The resulting damage to the core and the coil. So frequent on the gas
Check and adjust gap is an important condition to ensure operation. heat exchange manufacturers
2 pairs of particles connected spring plate adjustment group
Amplitude of the trough there are two factors: First, the feeder electromagnetic exciting force size, frequency, the second is the feeder's own natural frequency. According to mechanical vibration resonance principle known only when the feeder with the natural frequency of the excitation frequency close to the electromagnet resonance when the amplitude of the trough
Dual particle method for adjusting the spring plate group: adjustment of the machine to the air gap adjustment is completed, you can start to adjust the stiffness of the spring plate group. Loosen overhaul screw, connected to control power, a gradual increase in operating current at the same time, observed in the amplitude of the electromagnetic vibrating feeder signs
The indicated value. When the current reaches its maximum, and reach maximum amplitude can be set on the top of the spring plate screws slightly loose, then as the amplitude increases, the current decline, then the spring stiffness is too large, should reduce reed the number of blocks to reduce the stiffness. Instead it should increase the number of spring air to water heat exchanger
To enhance the overall stiffness. Short as long as the adjustment can be repeated carefully tuned to achieve the best value is to determine the role of the amplitude of vibration signs point vibration amplitude, measured two lines dividing point is the value of the amplitude values.
3 Installation and adjustment
(A) assembling the feeder, you must tighten the screws exciter connection with the trough, so as not to affect the stability of electromagnetic vibrating feeder operation. To ensure safe use of the grounding screw on electromagnetic vibrating feeder should be grounded.
(2) The electromagnetic vibrating feeder suspended solid and reliable installation using rope or turnbuckle hanging in sufficient stiffness components, in order to reduce the electric vibrator slot to swing the boom can be hung in the width direction outward Zhang Open 10 ° arrangement.
(3) In order to reduce the silo material on the trough of pressure in the silo must be installed with a certain inclination chute, and not touch the chute chute.
(4) should be located at the discharge opening gates spout width B must satisfy the following formula: A - 20> B> (2-3), d where: d - maximum material size (mm) A - material slot width (mm).
(5) When the tank can downwardly inclined 10 °, if the electronic program control unit to be mounted horizontally supporting the use and check the horizontal level the tank, otherwise the material during transportation to the side shift.
(6) After installation of vibrating feeder, swimming around there should be a gap, the electric vibrator in a free state.
(7) closed tank vibration motor can be installed material inlet and outlet dust bag, suitable for applications requiring dust in the environment.
