Vibration isolation spring aging is a common fault during the operation of vibrating fluidized bed. In order to ensure the stable and efficient operation of the equipment, sufficient attention must be paid to the aging of the vibration isolation spring. Replacement should be considered as soon as the isolation spring is found to be aging and cracking, or if its installation height is less than the recommended 105 mm.
It is important to note that if the isolation springs need to be replaced due to improper installation height or aging problems, it is recommended to replace all the isolation springs at once. This is done to ensure the overall stability and balance of the vibratory fluidized bed. At the same time, in order to ensure that the replaced vibration isolation springs can work normally, the free height error of each group of rubber springs should be controlled within the range of no more than 3 mm.
In the process of replacing rubber springs, strict operating procedures must be followed. The first principle is that all rubber springs must be replaced at the same time, and one or several cannot be replaced individually. In addition, the center of gravity of the equipment must be balanced when lifting or pushing the vibratory fluidized bed during the replacement process. To achieve this, it is advisable to use jacks for auxiliary operations and to ensure that all jacks are lifted consistently. At the same time, during the replacement process, the rotation distance should be reduced as much as possible to reduce the potential impact on other parts of the equipment.
Finally, it is crucial to carry out a rigorous inspection of the replaced rubber springs. This includes checking the height of its installation, the error of the free height, and the presence of cracks.
