Reduce airflow pulverizer strong vibration seven Method
When we use the airflow crusher, sometimes the body will have a strong vibration, then what is the cause of the crusher's strong vibration? Let's take a look.
1, the hammer installation error in maintenance assembly. When the hammer is turned off, in order to prevent the weight of the rotor from losing balance, all the hammers in the pulverizer must be turned out together, otherwise it will have a strong vibration in the operation.
2, the difference between the weight of the two sets of hammer exceeds 5 grams. The method of excluding is to adjust the weight of the hammer, so that the difference between the corresponding two groups is less than 5 grams.
3, individual hammer card is too tight, there is no open in operation. After the stop, turn the observation by hand, think of the way to turn the hammer flexible.
4, other parts of the rotor are unbalanced, and the adjustment balance needs to be carefully checked.
5, the spindle bending deformation. The solution is to school straight or replacement.
6, the bearing gap exceeds the limit or damage. It is generally used to replace new bearings to solve the problem.
7, the bottom angle fixing nut is not fixed or running. The solution is tightened.
