ZD Type Damping Spring Damper Characteristics:
Vibration and noise can affect the surrounding environment, harm human health, damage buildings, and reduce the accuracy of machinery and equipment, especially causing interference to the use of valuable instruments. Moreover, the vibration generated can also damage the machine itself, 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 at low damping ratios. It can protect the isolation efficiency from dropping 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, achieving vibration isolation at high, medium, and low interference frequencies, while also featuring the high damping ratio of rubber shock absorbers. This allows for the elimination of the unique resonance phenomenon of steel springs, 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 over the resonance zone during start-up and shutdown, maintaining balance without swaying, with an isolation efficiency of ≥85%. This shock absorber does not require a large concrete base, can bear 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 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, offering benefits such as fatigue resistance, high strength, large load-bearing capacity, and long service life.
Main Application: Suitable for all types of dynamic rotating machinery such as fans, pumps, compressors, generators, air conditioning boxes, water-cooled units, cooling towers, etc.
Our factory produces three models of products:
Standard Vibration Absorber
2: Fixed Mount 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 select according to their specific needs (Note: The height of the adjustable vibration dampers is increased by 20mm)
