How to address the vibration in the mixing pipeline at the top of the polypropylene granule silo?
Thread Content
I would like to ask everyone: has anyone encountered a situation where the pipeline entering the silo after the elbow at the top of the polypropylene pellet silo experiences significant vibration? How to solve this? I climbed to the top and checked; it’s not very suitable for fixing with bolts. The vibration is significant; the vibration of the pipes at the top can be seen even at the bottom of the silo. Are there standards for the magnitude of vibration? I have never heard of any accidents caused by pipeline vibration. It’s not appropriate to propose corrections without any basis.
Is it the vibration of the pneumatic conveying pipeline? Reducing the conveying speed can minimize vibration. The method is to minimize the air volume of the fan as much as possible, without affecting the delivery volume.
Thank you, moderator. We use pneumatic conveying, but the capacity cannot be reduced.
Reinstall the large I-beam supports from the overpass and fix them with bolts; that’s how our factory handles it, and the results are quite good. Check the supports on the side of the tank; they must all be secured.
