ZD Type Damping Spring Damper Characteristics:
A variety of 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 itself can damage the machinery, shortening its lifespan. Therefore, isolating vibration with elastic elements and preventing 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 (for higher damping ratio, 0.085). Therefore, our shock absorbers possess the low-frequency characteristics of steel spring shock absorbers, achieving vibration isolation at high, medium, and low interference frequencies while also having the high damping ratio characteristic of rubber shock absorbers. This allows for the elimination of the unique resonance phenomenon of steel springs, ensuring smooth operation from start to stop without excitation (amplitude A=0.01mm) and a stopping 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, maintaining balance, with an isolation efficiency of ≥85%. This shock absorber does not require anchoring to large concrete bases, 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 suspension shock absorber.
Our vibration dampers are equipped with springs made from 60Si2Mn spring steel, which offer excellent fatigue resistance, high strength, large load-bearing capacity, and long service life.
Main Application: Suitable for all types of power rotating machinery such as fans, pumps, compressors, generators, air conditioning units, chilled water units, cooling towers, etc.
Our factory's products are available in three models:
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)
