The ZD type damping spring shock absorber combines the dual advantages of a spring shock absorber's low frequency and a rubber shock absorber's high damping. By integrating these two strengths, it eliminates the phenomenon of amplitude surge during resonance in spring shock absorbers and also solves the problem of a higher natural frequency in rubber shock absorbers, making it an ideal product for active and passive isolation damping.
The ZD type damping spring shock absorber has a wide load range and strong adaptability. It can produce a significant effect on active, passive, and impact isolation simultaneously, making it a multi-functional general-purpose isolation product. It is suitable for working environments between -20°C and 80°C. The natural frequency within its normal working load range is between 4.5HZ and 4.9HZ, with a damping ratio of 0.065. It is an ideal shock absorption product for air conditioners, temperature control equipment, fans, cooling towers, refrigeration units, compressors, water pumps, and other equipment.
Applicable Equipment: Air Conditioners,恒温Equipment, Fans, Cooling Towers, Refrigeration Units, Compressors, Transformers, Pumps, Air Energy, etc.
