ZD Type Damping Spring Damper Features:

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 with the use of valuable instruments. Moreover, the vibration itself can damage the machinery, shortening its service life. Therefore, using elastic elements to isolate vibration and prevent its transmission is an ideal method to eliminate vibration, 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 (with a higher damping ratio of 0.085). Therefore, our shock absorber combines the low-frequency characteristics of steel spring shock absorption with the high damping ratio of rubber shock absorbers, eliminating the unique resonance of steel springs, thus ensuring no excitation (amplitude A=0.01mm) during the transition from start to stop, 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 without swinging, achieving 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. It can also be mounted without the need for anchor bolts, significantly reducing the installation time. It is a simple, moderately priced, and versatile multi-functional damping spring suspension 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 Application: Suitable for all kinds of power rotating machinery such as fans, pumps, compressors, generators, air conditioning units, chilled water units, cooling towers, etc.
