وحدة التغذية الاهتزازية الكهرومغناطيسية (نوع التعليق)

سمات:

(1) Energy saving and high efficiency, simple to use, less investment, small volume, light weight, convenient maintenance.

(2) No rotating parts. No need bearings, reducingmechanism and lubricating oil etc.

(3) Less power consumption, small startup current, low noise.

(4) The feed trough wear is small. Suitable for conveying material with big wear and tear

(5) The equipment can realize automation if equiped with electronic scale or microcomputer control.

(6) After vibrationexciter starts,  the amplitude can instantaneously achieve stable value.

(7) Vibrator start in instantaneous amplitude can achieve stable value, immediately after the same instantaneous amplitude disappears when parking, which can enhance the accuracy of automatic control, at the same time feeder can start directly in full load condition. Similarly, amplitude instantaneously disappears when stopping. In this way can enhance the accuracy of automatic control, and at the same time, the feeder can be directly started at full loading case.

مبدأ العمل:

  The current of electromagnetic coil of electromagnetic vibration feeder passes through single phase half-wave rectification. When the coil is connected, the current passes through in the positive half week, and a pulse electromagnetic force between armature and iron core attracts each other. Then the groove moves backwards, the main spring deforms and stores a certain potential energy. There is no current passing through the coil in the negative half-cycle, and the electromagnetic force disappears, and the main spring releases energy. The armature and iron core move forward from the groove in the opposite direction, so the electromagnetic vibration feeder vibrates 3000 times per minute at the frequency of AC power supply. Because the bottom plane of the groove has a certain angle with the action line of exciting force, the material in the groove moves forward continuously along the parabolic trajectory. The feeding quantity of electromagnetic vibration feeder can be controlled by adjusting the rectifying voltage. The feeder is supplied by SCR rectifier. The output voltage can be controlled by changing the conduction angle of thyristor. According to the operating conditions, different signals can be used to control the conduction angle of thyristor to achieve the purpose of automatic quantitative feeding.
