Passive vibration isolation system
Thin film air springs have precise and adjustable damping for low-frequency thin film air springs, which can be used in sensitive measurement and testing equipment, precision machining machines, laser equipment and optical electronic instruments, as well as vehicle, engine, and gearbox test benches, and have effective vibration reduction and isolation effects.


The thin film air spring isolator consists of a cast aluminum body. The air chamber is surrounded by a thin walled flexible diaphragm. Its plunger is installed on the diaphragm and pushed into the air chamber. This design has a high isolation effect. In order to achieve the highest possible damping effect, the air position is divided into two chambers. In order to suppress resonance amplification and increase damping, the internal chambers are divided into a bearing chamber and a damping chamber, which are connected by an air hose. By adjusting the valve, the damping effect can be easily adjusted from the outside. Due to the friction phenomenon caused by air flowing through the bypass valve, up to 15% of the damping will be affected. The added safety valve will protect the roller diaphragm and prevent the spring from being damaged due to excessive inflation.

▪ Efficient vibration isolation effect
▪ Sensitive measurement and detection equipment
▪ Accurate sorting machine
▪ Laser equipment and optical and electronic instruments
▪ Vibration isolation bearings for vehicle, engine, and gearbox test benches
▪ Foundation vibration isolation

Advantages compared to traditional steel springs:
The diaphragm air spring of the horizontal control device can continuously adjust the correct level of the machine and foundation, and the horizontal adjustment and control are fully automatic. The pressure in the air spring can be adjusted appropriately by inflation or deflation according to load changes. This keeps the isolation effect constant in every situation. Unlike steel springs, air springs do not transmit structural noise.

Active vibration isolation system
This system is a vibration isolation system with extremely high requirements for isolation effect, deviation, and horizontal stability.


▪ The active electronic pneumatic control system can provide 6 degrees of freedom for control
▪ Air spring as passive actuator
▪ Efficient vibration isolation, no resonance peaks
▪ Excellent displacement accuracy control in both horizontal and vertical directions
▪ Minimum displacement and settling time in response to changes in machine load
▪ Powerful real-time control
▪ Under the management and control of the PLC control box and CAN bus, each degree of freedom is controlled by a controller and a high-speed electronic servo valve
▪ Each controller consists of a microprocessor and a set of integrated high-resolution sensors that control displacement, air pressure, and acceleration
▪ Through intelligent software WinSNI or Web Visu, the entire system can be easily and quickly optimized, adjusted, monitored, and diagnosed
▪ Implement simple switching between two modes: scanning mode (for sensitive machine equipment and instruments with high isolation requirements) bearing mode (for machine equipment and instruments with frequent load changes)
▪ No need for device to provide front feedback signal
▪ No interference heat, magnetic changes, or high power consumption caused by electromagnetic starters or motors
