Characteristics of ZD type damping spring shock absorber:
Varying vibration and noise can affect the surrounding environment, harm human health, damage buildings, and reduce the accuracy of machinery and equipment, particularly causing interference with the use of valuable instruments. Moreover, the vibration generated can also damage the machine itself, shortening its lifespan. Therefore, using elastic elements to isolate vibration and prevent its transmission is an ideal method to eliminate vibration and protect the environment, buildings, machinery, and equipment.
Our factory's shock absorber design incorporates the characteristics of steel spring shock absorbers, overcoming the phenomenon of resonance when the damping ratio is low. It can protect the isolation rate from decreasing when the damping ratio is increased to 0.15-0.18 (for higher damping ratio, 0.085). Therefore, our shock absorber combines the low-frequency characteristics of steel spring shock absorption, achieving vibration isolation for high, medium, and low interference frequencies, while also having the feature of a high damping ratio typical of rubber shock absorbers. This allows for the elimination of the unique resonance phenomenon of steel springs, ensuring no excitation (amplitude A=0.01mm) from start to stop during equipment operation, with a stop time of 1.6 seconds. After installing the shock absorber, the equipment can quickly pass through the resonance zone during start-up and shutdown, maintaining balance without swinging, with an isolation effect of ≥85%. This makes the shock absorber unnecessary to be anchored to large concrete bases, capable of supporting the total weight of the equipment, and can be installed on the ground, floors, or platforms. Additionally, it can be mounted without the need for ground bolt fastening, significantly reducing the installation time. It is a simple, speed-appropriate, and economically reasonable multi-functional universal damping spring shock absorber.
Our shock absorbers are made with 60Si2Mn spring steel, which boasts excellent fatigue resistance, high strength, large load-bearing capacity, and long service life.
Main Applications: Suitable for all types of rotating machinery such as fans, pumps, compressors, generators, air conditioning units, water-cooled chillers, cooling towers, etc.
Our factory offers three models of products:
Standard Vibration Damper
2: Fixed Mounting Vibration Dampers
3: Low-frequency adjustable vibration dampers (operate normally in -30℃ to 100℃ environment, natural frequency ranges from 1.8Hz to 3.6Hz, damping ratio is 0.04-0.066) - Users can choose according to their own needs (Note: The height of the adjustable vibration dampers is increased by 20mm)
