ZD Type Damper 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 disrupting the use of valuable instruments. Moreover, the vibration generated can also damage the machinery itself, shortening its lifespan. 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, achieving vibration isolation for high, medium, and low interference frequencies, while also having the feature of a high damping ratio like rubber shock absorbers, which can eliminate the resonance phenomenon unique to steel springs. This ensures that there is 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, remaining balanced and non-turbulent, with an isolation effect of ≥85%. This allows the shock absorber to support the total weight of the equipment without the need for a large concrete base, and can be installed on the ground, floors, or platforms. Additionally, it can 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 shock absorbers are made with 60Si2Mn spring steel, offering advantages such as fatigue resistance, high strength, great 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:
1: Standard Vibration Damper
2: Mounting-Type Vibration Absorber
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 own needs (Note: The height H of the adjustable damper is increased by 20mm)
