how to maintain the strong vibration of pulverizer?
In rural areas, common to the initial installation of the hammer pulverizer at commissioning a strong vibration in the airframe. This occurs mainly in the following reasons:
(1) Maintenance hammer assembly is installed wrong. Noodles hammer for the U-turn when used to prevent the rotor out of balance weight, all the hammer noodles of pulverizer to be together for the U-turn, otherwise they will be running at a strong vibration.
(2) correspond to the two groups hammer weight difference more than 5 grams. Ways are adjusted to exclude the weight of hammer, so that the weight difference between the corresponding two groups of less than 5 grams.
(3) individual cards hammer too tightly, do not run away. Hand rotation can be observed after the shutdown, I would like to make a flexible rotating hammer.
(4) Rotor weight imbalance on the other parts, when necessary, respectively, double-check the adjustment and balance.
(5) spindle bending deformation. The solution is to align or replaced.
(6) bearing clearance over the limit or damaged. Are generally used bearings replaced with new ones in order to solve the problem.
(7) do not have a fixed angle fixed nut running loose or tight. The solution is to fastening.
