Ultra-low frequency vibration (0.5 – 10Hz) has always been an extremely difficult and difficult-to-control industrial vibration problem in the fields of energy, heavy equipment, industrial machinery, and laboratories. It is also the core bottleneck restricting the precision and automation upgrades of high-end industries.
Due to the high natural frequency, domestic vibration isolation technology is completely ineffective in ultra-low frequency vibration isolation, making it unable to solve pain points such as resonance, accuracy drift, and poor stability.
The imported original active spacers and air springs have achieved a revolutionary breakthrough in ultra-low frequency vibration control technology.
The hazards of ultra-low frequency vibration cover the entire scene.
In energy units, the core resonance frequency is between 0.5 and 5Hz, which can easily cause equipment fatigue failure; low-frequency vibrations caused by heavy-duty impacts on heavy equipment can cause processing accuracy to drift; low-frequency coupled vibrations during industrial machinery automation can reduce production line stability; laboratory nanodevices are extremely sensitive to ultra-low-frequency environmental vibrations, and once affected, experimental data will be distorted.
However, the natural frequency of domestic vibration isolation is generally greater than 3Hz, which not only fails to isolate ultra-low-frequency vibrations, but also resonates to amplify vibration hazards, becoming a huge obstacle to high-end automation upgrades.
Imported air springs have achieved a breakthrough in ultra-low frequency passive vibration isolation technology.
It adopts a patented non-linear ultra-low frequency stiffness design that can accurately reduce the natural frequency to the extreme level of 0.5 – 1Hz, cutting off the transmission path of 0.5 – 10Hz ultra-low frequency vibration from the physical source. The ultra-low frequency vibration isolation efficiency exceeds 99%, completely solving the pain point of domestic ultra-low frequency vibration isolation failure.
In addition, it uses a three-layer composite aramid fiber capsule and a precision-sealed design, which can carry a heavy load of 50-100 tons. It also has a dynamic adaptive leveling function. Its long-term ultra-low-frequency vibration isolation performance is stable and without attenuation. Its service life can reach 15-20 years, and its durability far exceeds domestic products.
Imported active spacers realize the innovation of ultra-low frequency active vibration suppression technology.
Its six-degree-of-freedom integrated decoupling structure can fully capture ultra-low-frequency micro-vibrations starting at 0.1Hz. The imported original AI algorithm can respond extremely quickly within 30ms, actively offset ultra-low-frequency vibration interference, and control residual vibration at the nanometer level.
It can actively suppress the endogenous ultra-low frequency vibration and impact vibration of the equipment in real time, and is combined with the air spring to passively isolate the foundation vibration from ultra-low frequency, forming a full-range ultra-low-frequency vibration control system of active vibration suppression + passive isolation. The suppression rate of ultra-low-frequency vibration in the full frequency band exceeds 95%, and the operational stability and positioning accuracy have reached the top international level.
Ultra-low frequency control technology innovation directly empowers automation upgrades.
In the energy industry, it can eliminate ultra-low frequency resonance, ensure safe and stable operation of units, and facilitate smart energy automated operation and maintenance; in the field of heavy equipment, it solves the problem of low-frequency impact accuracy drift and realizes automated precision processing; in industrial machinery, it eliminates low-frequency coupled vibrations, greatly improving the accuracy and stability of automated production lines; in laboratories, it completely isolates ultra-low frequency environmental vibrations, enabling nanometer-level automated precision scientific research.
Compared with the backward domestic ultra-low frequency vibration isolation technology, imported active spacer air springs have all-round technological leadership.
With its imported high-quality and highly reliable structure, stability, precision and durability, it leads the development of high-end industrial ultra-low frequency vibration control technology and is a core vibration isolation solution necessary for high-end automation upgrades in the four major industries.
