application field

Spring isolators utilize the low stiffness and high elasticity characteristics of metal coil springs to provide flexible support between equipment and foundations. Its core function is to effectively isolate and attenuate the transmission of vibration energy by extending the natural period of the system, mainly solving the problem of mid low frequency vibration, and widely used in the following key fields:

Core application areas

Precision instruments and industrial equipment

Application scenarios: precision machine tools, coordinate measuring instruments, semiconductor manufacturing equipment, laser instruments, electron microscopes, etc.

Solution: Isolate environmental vibrations from the ground (such as traffic and nearby equipment operation) to ensure the measurement accuracy, processing quality, and stable operation of the equipment.

Building floor and floating floor

Application scenarios: recording studios, hospitals (MRI, CT rooms), laboratories, equipment floors in high-rise buildings, and high-end office buildings.

Solution: Build a "floating" vibration isolation system between the floor slab and the decorative ground, effectively blocking the transmission of equipment vibration to the building structure, reducing solid sound transmission, and creating a quiet and interference free environment.

Large power equipment

Application scenarios: chillers, fans, water pumps, stamping equipment, generator sets, etc.

Solution: Isolate the mid to low frequency vibrations generated by equipment operation, prevent them from being transmitted outward through foundations and pipelines, protect building structures, and reduce noise pollution.

Buildings along the rail transit line

Application scenarios: Buildings on top of subways, sensitive buildings along railways.

Solution: Install vibration isolation layers on the building foundation or specific floors to significantly reduce the sustained micro amplitude vibration caused by subway or train operation and improve building comfort.

working principle

The spring isolator forms an elastic support between the equipment and the foundation through a spiral spring. Its working principle is to utilize the low natural frequency (f ₀) of the system to make it much lower than the equipment vibration frequency (f). When the frequency ratio f/f ₀>√ 2, the vibration energy is isolated by the deformation of the spring, and most of the kinetic energy is blocked at the device end, unable to be transmitted to the basic structure, thus achieving vibration isolation. The system controls the resonance amplitude by adjusting stiffness and damping, ensuring effective isolation of mid to low frequency vibrations.
