2. The equipment relies on the magnetic wave of magnetic field and does not need motor, so the equipment has no rotating parts and does not need regular lubrication. It has simple structure and convenient maintenance.
3. Centralized control of process operation reduces labor consumption.
 
 Maintenance skills of electromagnetic feeder
 
The advantage of the feeding groove is that it can change the feeding trajectory at any time.
5. Because it works in the low critical near resonance state, the vibration mechanism is advanced and the energy consumption is low. Because the material flow can be changed or opened and closed instantaneously, the feeding rate has high accuracy.
6. The equipment can adopt sealed structure, so it can send materials with heavy pollution and easy to raise dust. Moreover, the trough made of alloy steel plate can be used for conveying materials with high temperature, serious wear and corrosion.

working principle

Electromagnetic vibration feeder structure is relatively simple, small size, light weight, good airtight feeding, suitable for small particle size and powder materials. The device is a tuned two particle near resonance system, which works in a low critical state. When the power supply is connected, the electromagnetic coil of the electromagnetic vibrator is supplied by single-phase half wave rectification. When the line is connected to the power supply, a voltage is applied to the electromagnetic coil within the positive half cycle. Therefore, the electromagnetic coil has current passing through. Pulse electromagnetic force is generated between the armature and the iron core, which attract each other. In the negative half cycle, the electromagnetic force disappears, and the armature is relative with the potential energy stored in the spring plate The iron core moves in the opposite direction, so that the feeding trough of the feeder moves back and forth in the direction of exciting force at the frequency of AC power supply, and drives the materials in the trough to move forward continuously and slightly along the parabola shape to achieve the feeding purpose.

Common faults

Fault 1: since it is a mechanical equipment, it must be inseparable from the power supply. Once the equipment is powered on, the equipment still does not work.
Solution: check whether the fuse of the equipment is broken, whether there is a short circuit in the circuit or whether the wiring is wrong or the circuit is broken. The best way is to use a megger or ohmmeter to check whether the resistance is short circuited or connect the outgoing line.
Fault 2: the overall vibration of the equipment is relatively weak and the current is high. Even if the amplitude of potentiometer is adjusted, it is difficult to adjust the vibration and current to the best.
Solution: there is a thyristor inside the equipment, which can adjust the current size of the equipment, check whether it is broken down or damaged, and replace it with a new one in time. Also see whether the air gap of the equipment and the gap between the leaf spring are blocked. If it is blocked, the blockage should be removed in time.
Fault 3: the equipment is noisy in operation, even if the amplitude of potentiometer is adjusted, there will be violent noise.
Solution: check whether the connecting bolts between the vibrator and the material trough are broken and loose. Tighten the bolts in place, or check whether there is collision between the iron core and the armature. If there is timely adjustment, it can be solved.
 
 Common faults of electromagnetic vibration feeder
 
Fault 4: the normal operation of the equipment is that the current is too high.
Solution: the reason is likely to be that the gap between the air gap and the thyristor is too large. Adjust the gap to about 2mm.
Fault 5: the current of the equipment is unstable, sometimes high and low, resulting in intermittent operation of the equipment.
Solution: to check whether there is short circuit in the coil layer or between turns of the equipment line, or whether there is virtual connection at the connector of the outgoing line, if the coil is repaired or replaced in time.
Fault 6: when the equipment runs normally during no-load test run, the amplitude of the loaded equipment will decrease a lot, especially abnormal.
Solution: a large part of the reason is that the design of the discharge port of the material bin of the equipment is unreasonable, which causes the material column pressure of the material trough to be too large. Therefore, it is necessary to seek professional and technical personnel to redesign the discharge port or modify the discharge port, so as to reduce the pressure of the material column.
 
 Solution of electromagnetic vibration feeder

Installation method

1. The electromagnetic vibration feeder is generally installed in suspension type, and the suspender shall be installed on the structure with enough rigidity. In order to reduce the lateral swing of the electromagnetic vibration feeder, the suspension suspender shall be arranged with an outward opening of about 10 degrees. For the large feeder, in order to maintain and replace the trough is convenient, also should set up the mobile sliding frame.
2. The electromagnetic vibration feeder should be installed as a whole. Generally, it is not allowed to dismantle or fix any rigid accessories on the machine. During installation, there should be a certain space around the equipment to avoid collision with other equipment. Generally, the minimum space in the length direction is 50 mm, and the width direction is 25 mm.
3. The trough of electromagnetic vibration feeder can be installed horizontally or tilted. Its feeding capacity is directly proportional to the downward inclination angle. However, if the downward inclination angle is too large, it is easy to cause material self flowing and it is difficult to ensure the feeding accuracy. Therefore, it is necessary to determine whether the material is inclined upward, downward or horizontally according to the nature of the material.
4. After installation, the feeder should be in horizontal state horizontally to avoid material deviation to one side when the feeder is working, and ensure that all fastening bolts are firmly fastened.
 
 Installation method of electromagnetic vibration feeder
 
Air gap adjustment
 
The air gap between the iron core and the armature of electromagnetic vibration feeder directly affects the normal operation of the electromagnetic vibration feeder. If the adjustment is improper, the light one will increase the current and reduce the amplitude, which will cause the equipment not to run normally. In serious cases, the iron core will collide and the iron core and coil will be damaged.
The gap between the iron core and the armature is generally 1.8 ~ 2.0 mm, which can be appropriately reduced or expanded according to the feeding amount. If the air gap is too small, the amplitude will be reduced and the current and power consumption will be increased; if the air gap is too small, it will cause the impact between the armature and the iron core and damage the parts. The size of air gap should be checked frequently and adjusted properly in production.
The adjustment method of air gap is as follows: firstly, adjust the position of connecting fork with maintenance screw, then adjust the size of air gap with feeler gauge, fasten reliably and add lock nut. In addition to maintaining a suitable air gap, the working faces of the iron core and the armature should be parallel to each other to ensure that the action line of the excitation force passes through the center of gravity of the feeder trough. At the same time, attention should be paid to make the center line of the electromagnetic vibrator and the center line of the tank body be in a vertical plane, otherwise the feeder will be inclined when working.
