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, 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 and 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, achieving vibration isolation for high, medium, and low interference frequencies, while also featuring a high damping ratio like rubber shock absorbers. It can eliminate the unique resonance phenomenon of 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 shock absorber, the equipment can quickly pass through the resonance zone during start-up and shutdown, maintaining balance without swaying, with 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. Additionally, it can be mounted without the need for anchor bolts, significantly reducing the equipment installation time. It is a simple, speed-appropriate, and economically reasonable multi-functional universal damping spring suspension shock absorber.
Our shock absorbers are made with 60Si2Mn spring steel, offering advantages such as fatigue resistance, high strength, large bearing capacity, and long service life.
Main Applications: 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 offers three models of products:
Standard Damper
2: Fixed Mount Dampers
3: Low-frequency adjustable shock absorber (operates normally at -30℃ to 100℃, with a natural frequency of 1.8Hz to 3.6Hz and a damping ratio of 0.04-0.066) - Users can choose according to their own requirements (Note: The height of the adjustable shock absorber 3 is increased by 20mm)
