Universal crusher uses the high-speed relative motion of the movable tooth plate and the fixed tooth plate to make the object crushed by the tooth impact, because it is in the high-speed movement so it will not inevitably occur vibration phenomenon, this phenomenon of small amplitude vibration is very normal, but once a large amount of vibration will attract attention, The most common is that the universal crusher has a strong vibration in the fuselage during trial operation after maintenance. Many people do not know what causes it, can not find the key to vibration, and let it go for a long time. Such behavior is very bad, not only affects the life of the universal crusher to a large extent, but also makes the material not well crushed, so in view of this phenomenon, professionals have specifically studied the cause of large vibration. There are several reasons:
1, individual hammer card is too tight, the operation is not thrown off. Can be stopped by hand rotation observation, find a way to make the hammer flexible rotation.
2, repair assembly hammer installation error. When the hammer is used, in order to prevent the weight of the rotor from losing balance, all the hammer pieces in the crusher must be changed together, otherwise strong vibration will occur during operation.
3, the main shaft bending deformation. The solution is to straighten or replace.
4, the difference between the weight of the two groups of hammer is more than 5 grams. The method of elimination is to adjust the weight of the hammer so that the difference between the corresponding two groups of weight is less than 5 grams.
5, the grinder bottom Angle fixed nut is not fixed tight or loose in operation. The solution is to tighten.
6. Bearing clearance exceeds the limit or is damaged. Generally, the replacement of new bearings can solve the problem.
7, the weight of other parts on the rotor is not balanced, then you need to carefully check and adjust the balance.
8, the above problems can not be solved by the customer, it is recommended that the customer contact the manufacturer.
