What are the common faults of vibrating screen? How to eliminate the trouble of vibrating screen?
Abnormal motion of material flowReason：1) the horizontal level of the screen box is not straight2) the support spring is too large or damaged3) the screen surface is damaged4) the feed is extremely unbalancedTroubleshooting:1) adjust the height of the support2) adjusting spring3) adjust the screen surface4) uniform operation, stable feeding
In normal operation, the rotation of the sieve machine slows down and the bearing is heatedFailure cause:1) the bearings lack lubrication oil2) bearing block3) excessive oil in the bearings or improper oil added4) bearing damage or poor installation, eccentric block on the round off, eccentricTroubleshooting:1) inject lubricating oil into the bearings2) clean the bearing, replace the sealing ring, and check the labyrinth sealing device3) check the lubrication of the bearing4) replace the bearing, install the eccentric block, adjust the round wheel
The sieving quality of vibrating screen is poorReason：1) the mesh is blocked2) the moisture of the sieve increases3) the feeding of the machine is uneven4) the screen surface is too thick5) the screen does not pull tightly and the belt is looseTroubleshooting:1) uniform operation, stable feeding2) reduce the load of vibrating screen machine and clean the screen surface3) change the angle of the screen box4) adjust the feeding of the sieving machine5) reduce the feeding of the screening machine6) tighten the screen mesh and tighten the drive belt
Common troubles and elimination methods of vibrating screen:(1) make sure the power is on and the switch is on.(2) the cable length is not enough to make the contact bad; the cable should be replaced.(3) whether the cable is broken or not; the cable should be replaced.(4) unidirectional movement causes the coil to burn off; should replace the electric machinery.(5) injecting too much lubrication; to keep it running(6) the collar ring screw is not locked; the lock nut(7) the ring is not securely fitted; locks the copper nut(8) instability of abutment; stable base(9) the spring is broken; replace the spring(10) the body is in contact with other hardware; the space is about l0 centimeters apart.(11) loosening of motor alloy steel screws; Determination of locking(12) the discharge port is in contact with it; does not touch it.(13) the running direction of the motor is wrong; the order of contact of the power line is changed.(14) the angle between the upper and lower eccentric blocks is too large; the angle is less than 90 degrees.(15) the upper and lower eccentric block device is wrong; the heavy eccentric block is on the upper light eccentric block.(16) the material directly impacts the net surface; the buffer is used.(17) not to replace the mesh tension.(18) the rough net has been damaged; replace the rough net.(19) rubber pad is worn thin; replace.(20) connecting heavy pipes or hanging weights; isolating exports.(21) the bundle ring is not uniformly locked; the locking ring is locked.
The shaker cannot start or have a smaller amplitudeReason:1) motor damage2) the electrical components in the control circuit are damaged3) lack of voltage4) the screen surface material accumulation too much5) the vibrator is out of order6) the grease inside the vibrator becomes thick and agglomerateRemoval method:1) replace the motor2) replace electrical components3) change the power supply4) cleaning screen material5) overhaul vibrator6) clean the vibrator and renew and add proper grease
