The vertical vibration value of a cement plant’s grinding mill once increased sharply to 40.2mm/s due to a design defect in the support seat, causing the equipment to be frequently shut down for maintenance; the reactor of a chemical plant had three gear fatigue fracture accidents within half a year due to the weak foundation of the bearing seat. These seemingly accidental “shaking” phenomena all point to the “invisible killer” of the same industrial equipment – the support seat.
The support seat is not only a connecting component between the equipment and the ground, but also a key core component to ensure the smooth operation of the equipment. Its functions can be roughly summarized into the following three points:
- Shock absorption and buffering: Through springs, dampers and other structures, the impact force during the operation of the equipment is absorbed, thereby reducing the vibration amplitude. For example, after a certain electronics factory customized a shockproof support seat, the vibration of the equipment was reduced by 40%.
- Precise alignment: Ensure that the axis of the equipment is accurately aligned with the foundation to prevent axial vibration caused by “eccentric load”. In the automobile production line, if the support seat is not well aligned, it will cause a deviation in the repeat positioning accuracy of ±0.005mm.
- Extend life: High-quality support seats can reduce bearing wear and reduce maintenance costs. It is common that food machinery factories have reduced equipment failure rates by 25% by optimizing support seats.
