Rotating parts such as shafts, rollers, and impellers will produce centrifugal force when their mass distribution is uneven. Long-term operation, partial wear, or local material adhesion will aggravate mass imbalance, generating continuous periodic vibration.
Deviated installation position, mismatched assembly clearance, and misaligned transmission components will change the running track. Fasteners and connecting structures loosened by long-term vibration will further enlarge vibration range and cause resonance.
Worn bearings, deformed connecting parts, and cracked structural components will lose original matching accuracy and rigidity. Defective parts cannot operate stably, which directly triggers obvious vibration during movement.
Long-term operation under overload, excessive running speed, or unstable frequency will exceed the designed bearing capacity of equipment. Mismatched parameters will break the stable running state and intensify vibration.
Unleveled and insufficiently reinforced installation foundations cannot absorb vibration effectively. In addition, vibration transmitted from surrounding facilities and harsh on-site environment will also cause equipment vibration to exceed the standard.
Clean attachments on the surface of rotating components and conduct dynamic balance testing and correction. Trim or adjust unbalanced parts to reduce eccentric centrifugal force and eliminate vibration sources fundamentally.
Disassemble and reposition deviated parts strictly in accordance with technical standards to correct assembly deviation. Check all fasteners one by one and reinforce loose parts. Adjust the matching clearance of transmission structures to a reasonable range.
Inspect worn, deformed, and cracked components comprehensively. Repair repairable structures and replace severely damaged parts in a timely manner to restore the overall structural rigidity and matching precision of equipment.
Adjust running speed, load, and working frequency reasonably according to equipment performance requirements. Avoid long-term overload operation and frequent operation at sensitive frequency points to prevent resonance.
Level and reinforce the equipment installation base to improve stability. Add vibration damping structures at the connection positions to weaken the conduction of external vibration and reduce the superposition of vibration amplitude.
Establish regular inspection work to monitor vibration state, operating sound, and component temperature every day. Formulate standardized operation regulations to standardize startup, load adjustment, and shutdown procedures. Carry out periodic maintenance for key components, and eliminate hidden troubles such as part looseness and minor wear in advance.
Excessive vibration is usually caused by unbalanced parts, improper assembly, component damage, unreasonable parameters, and poor foundation conditions. Targeted rectification for existing faults can effectively reduce vibration. Combined with standardized operation and regular maintenance, the equipment can maintain stable operating status for a long time and avoid safety risks brought by excessive vibration.
