GERB-B Type Centrifuge and Press Damping Isolator
Why Are Centrifuges and Presses Suitable for GERB-B Type Damping Isolators?
The application of GERB-B type damping isolators in centrifuges and presses
When a press performs operations such as variable-speed running, slider movement, or cutting workpieces, it generates significant vibrations. These vibrations are unacceptable both for the workshop and the surrounding areas. Additionally, high-frequency components of the vibrations can induce secondary structural noise in nearby rooms.
By using the spring isolator and viscous damper vibration isolation system from Wuhan Zhonghong Precision Machinery, these vibrations and secondary noise levels can be greatly reduced. These measures are typically evaluated by vibration velocity. Compared to conventional installation methods, when a press is equipped with a spring-supported system with a vertical natural frequency of about 3Hz and a system critical damping ratio (proportional to vibration velocity) of about 30%, vibration velocity can usually be reduced by more than 90%. This system not only ensures the stable operation of the press but also allows it to return to its original position quickly after each stroke, facilitating automatic feeding.
Since the vibration isolation system significantly reduces the dynamic load transmitted from the press to the foundation, the foundation can be designed based on static load, greatly lowering construction costs.
The spring-damping vibration isolation system not only reduces the surrounding environmental vibration levels but also, through vibration measurement and long-term practical experience, helps reduce wear on the press, thus reducing maintenance frequency and extending the service life of the press, especially the molds.
Our company’s spring-damping isolator, developed based on advanced foreign technologies and expertise, consists of components like spiral steel springs, metal casings, damping materials, and fixed base plates. The isolator components use advanced surface treatment processes to ensure corrosion resistance and oxidation resistance, making it suitable for heavy loads, strong impacts, humid, dusty, and other harsh environments. The product requires no maintenance under normal use.
