Shaker common failure analysis and troubleshooting




   1, vibrating screen can not be started or amplitude is too small, you should check with Accessible electrical motor damage, or damage to the components in the circuit,

whether voltage is insufficient, these three areas had no problems, then from mechanical check, shaker screen surface material is stacked too much, and if so, that is clear.

Exciter on the coupling bolts without loss, whether grease caking thickens, then you can wash overhaul shaker, and then adjust the eccentric shaft is heavier block or vice

eccentric position.Linear vibrating screen
   2, the surface of the vibrating sieve material flow anomalies, one screen box insufficient stiffness, there is a critical frequency of vibration coupling bolts are loose, or

shake loose the full extent that the fastening. Second, the level of the lateral sieve box did not identify, from the supporting legs of the spring bearing seat or spring itself

to find fault, for spring or modified bearing size, there may be damage caused by mesh sieve surface, as long as you can replace the screen. If you have been due to insufficient

stiffness sieve box, did not identify the horizontal level, will cause beam break, such as material flow is still running but also make an exception. There may be improper

operation, namely feeding is one of the reasons is extremely uneven.
   3, vibrating sieve of poor quality due to improper operation of responsibility, probably mesh plug into the sieve material in the fine increases and water increased, the

oversize material layer is too thick, feeding inequality and so on. Debu may pull tight mesh on both sides, if it is eccentric shaft vibration, may drag the inability belt, belt

too loose, and other mechanical problems dealt with, you can come some time reverse rotation in order to improve the quality of screening.Mobile crushing plant
   4, shaker rotating slowly, bearing heating, this situation shows that did not keep the usual maintenance, lack of grease bearings, greased if it is new, it is the oil quality

problems or overfill, inferior oil to make it Bearing labyrinth seals jam blocking, so the quality of the grease is very important.
   5, circular vibrating screen noise is too large, it may be bearing damage, loose bolts, beams breakage and damage to the spring, in addition to the bolt can be tightened, the

other three conditions required replacement parts.
   6, shaker side cracks, broken beams, structural damage, such a situation will not arise suddenly, is the critical frequency of long working hours, for example, a large number

of high-strength bolts fastening side relaxation, severe deformation of the spring so very much about the level of difference, there may be eccentric blocks each weighing error

is too large, causing structural parts are damaged, wall cracks, and even beams broken, replace the damaged parts and tighten the bolt, the wallboard patching cracks must two

hit two 6m / m holes, to prevent crack extension, do not forget to fill strengthen board, in strengthening the board to play a few vents.
