Hazards of roof equipment vibration

Upload time:2025-06-04 Publisher:安立静

With the rapid development of society, science, technology, and the economy, space utilization has become increasingly important. To save space, mechanical and electrical equipment is often installed on the rooftops and floor slabs of main buildings or podium structures.

Typical rooftop and floor-mounted equipment includes:

  • Air-cooled heat pump units

  • Air energy

  • Various types of water pumps

  • Transformers

  • Chillers

  • Cooling towers

  • Fans

During operation, such equipment generates mechanical vibration and noise, which can seriously affect living and working environments.

Impacts of Vibration

1. Impact on projects and equipment

  • Vibration reduces overall project quality.

  • Continuous vibration shortens equipment service life and may cause premature damage.

  • Excessive vibration levels may lead to complaints if allowable limits are exceeded.

2. Impact on human health

  • Vibration and noise interfere with daily life and may affect human functional organs.

  • Long-term exposure to noisy environments can cause psychological stress and related health issues.

3. Impact on buildings

  • Long-term vibration can damage building structures, commonly resulting in cracks in foundations and walls, surface peeling, displacement, deformation, and foundation settlement.

  • In severe cases, structural safety may be compromised.

Requirements for Vibration Isolation

Rooftop equipment typically generates low-frequency vibration, often below 10 Hz. Conventional rubber and spring isolators have relatively high natural frequencies—approximately 12–15 Hz for rubber isolators and 7–8 Hz for standard spring isolators—resulting in limited isolation performance at low frequencies.

Therefore, effective vibration isolation requires vibration isolators with sufficiently low natural frequencies. To meet this demand, Anlijing has developed a new generation of low-frequency vibration isolators, along with corresponding selection and installation solutions to ensure optimal vibration control performance.
