Characteristics of ZD Type Damping Spring Damper:
A variety of vibration and noise can affect the surrounding environment, harm human health, damage buildings, and reduce the accuracy of machinery and equipment, particularly causing interference to the use of valuable instruments. Moreover, the vibration itself can damage the machinery, 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 damper design incorporates the characteristics of steel spring dampers, 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 damper, with the low-frequency characteristics of steel spring dampers, provides isolation effects for high, medium, and low interference frequencies while also having the feature of a high damping ratio like rubber dampers. It can eliminate the resonance phenomenon unique to steel springs, thus ensuring no excitation (amplitude A=0.01mm) during the transition from start to stop, with a stopping time of 1.6 seconds. After installing the damper, the equipment can quickly pass through the resonance zone during start-up and shutdown without swaying, achieving an isolation effect of ≥85%. This allows the damper to bear the total weight of the equipment without the need for a large concrete foundation, and can be installed on the ground, floors, or platforms without the use of anchor bolts, significantly reducing the installation time. It is a simple, speed-appropriate, and economically reasonable multi-functional universal damping spring hanger damper.
Our vibration dampers are made with 60Si2Mn spring steel, which boasts excellent fatigue resistance, high strength, great load-bearing capacity, and long service life.
Main Applications: Suitable for various power 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 Mount Vibration Dampers
3: Low-frequency adjustable vibration dampers (operate normally in -30℃ to 100℃ environment, natural frequency range of 1.8Hz to 3.6Hz, damping ratio of 0.04-0.066) - Users can select according to their own needs (Note: The height H of the adjustable vibration dampers is increased by 20mm)
