Electromagnetic vibration feeder common faults and solutions

       When the electromagnetic vibration feeder feeding equipment in one, in the course inevitably encounter various problems .
   
Troubleshooting
    1 power, electromagnetic vibration feeder does not shake
    (2) the noise is relatively large, tune coal production line rectifier or regulator has no effect , or a violent crash
    3 electromagnetic vibration feeder amplitude is small, and not much feeding amount
    4 . Regulator does not work, or weak shock adjustment potentiometer
    5 impulse or clearance work, work is not smooth
    6 Although the production is normal, but the current is large
Analysis of the causes of common
    1 for the first failure , possibly caused by the following reasons : ( 1 ) . Fuse is broken or open circuited ; ( 2 ) . Coil wire shorted ; ( 3 ) . Joints are decapitated ,

SCR is not conducting .
    (2) For the second failure , may have stone feeding machine the following reasons: ( 1 ) . Main springs ( spring or coil spring) fracture ; ( 2 ) . Tank connection with the exciter fork bolts

loose or broken ; ( 3 ) . Gap is too small ; ( 4 ) . Any increase in the weight of the machine
    3 for the third failure , may have the following reasons: silo discharge port design is unreasonable, excessive pressure to bear feeding trough
    4 for the fourth failure , may have the following reasons: ( 1 ) . Rectifier breakdown ; ( 2 ) . Coil wrong polarity ; ( 3 ) . Gap is expected clogged ; ( 4 ) . Plate spring

gap is blocked.
    5 for the fifth failure , may have the following reasons : a coil wire.
    6 Article for failure , may have the following reasons: ( 1 ) . Gap is too large ; ( 2 ) . Line package heat.
Solutions to common problems
    1 for the first failure , the solution is as follows: ( 1 ) . Replace the fuse and coil ; ( 2 ) . A search , replace the coil ; ( 3 ) . Connect fittings, conduction

thyristor . Should check all lines , specific treatment .
    2 for the second fault , the solution is as follows: ( 1 ) . Replace the main spring , and re- tuning ; ( 2 ) . Replace and tighten the bolts ; ( 3 ) . Adjust the air gap

large ( 4 ) Recovery
Machine normal weight.
    3 for the third failure , the solution is as follows : Improved nesting site structure , changing the discharge opening chute tilt angle , eliminating positions pressure

effect .
    4 for the fourth failure , the solution is as follows: ( 1 ) . Replace rectifier ; ( 2 ) . Grafting coil ; ( 3 ) . Clear materials to ensure the air gap ; ( 4 ) . Improve

housing sealed to prevent debris falling .
    5 for the fifth failure , the solution is as follows : Fix wires , replace the coil .
    6 For the sixth failure , the solution is as follows : Adjust the air gap size.
