ZD Type Damping Spring Shock Absorber Features:

Vibration and noise can affect the surrounding environment, harm human health, damage buildings, and reduce the accuracy of machinery and equipment, particularly interfering with the use of valuable instruments. Moreover, the vibration itself can damage the machine, shortening its lifespan. Therefore, isolating vibration with elastic elements and preventing its transmission is an ideal method to eliminate vibration and protect the environment, buildings, machinery, and equipment.

Our damper design incorporates the characteristics of steel spring dampers, overcoming the resonance phenomenon that occurs when the damping ratio is low. It can protect against a decrease in isolation efficiency when the damping ratio is raised to 0.15-0.18 (with a higher damping ratio of 0.085). Therefore, our damper, with the low-frequency characteristics of a steel spring damper, provides isolation for both high and low-frequency disturbances while also having the high damping ratio characteristic of rubber dampers. This allows for the elimination of the resonance phenomenon unique to steel springs, ensuring no excitation (amplitude A=0.01mm) during equipment operation from start to stop, with a stopping time of 1.6 seconds. After installing the damper, the equipment can quickly bypass the resonance zone during start-up and shutdown without swinging, achieving an isolation efficiency of ≥85%. This damper does not require a large concrete base, can support the total weight of the equipment, and can be installed on the ground, floors, or platforms. It can also be mounted without anchor bolts, significantly reducing installation time. It is a simple, moderately priced, multi-functional universal damper with damping spring suspension.

Our vibration dampers utilize 60Si2Mn spring steel springs, offering advantages such as fatigue resistance, high strength, great load-bearing capacity, and long service life.

Primary Application: Suitable for all types of power rotating machinery such as fans, pumps, compressors, generators, air conditioning boxes, chilled water units, cooling towers, etc.

Our factory offers three models of products:
