ZD Type Damping Spring Damper 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 itself can damage the machinery, shortening its lifespan. 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 at low damping ratios. It can protect against a decrease in isolation efficiency when the damping ratio is increased to 0.15-0.18 (with a higher damping ratio of 0.085). Consequently, our shock absorbers, while offering the low-frequency characteristics of steel spring dampers, achieve isolation effects across high, medium, and low-frequency disturbances. They also possess the high damping ratio characteristic of rubber shock absorbers, eliminating the unique resonance of steel springs. This results in no excitation (amplitude A=0.01mm) during startup to shutdown, with a shutdown time of 1.6 seconds. After installation of the shock absorber, the equipment can quickly pass over the resonance zone during startup and shutdown without swinging, ensuring an isolation efficiency of ≥85%. This makes the shock absorber unnecessary to be anchored to large concrete bases, supporting the total weight of the equipment, and can be installed on the ground, floors, or platforms without the need for ground bolt fixation, significantly reducing installation time. It is a simple, appropriately fast, and economically reasonable multi-functional universal type of damping spring suspended shock absorber.
Our vibration dampers 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 power rotating machinery, including fans, pumps, compressors, generators, air conditioning units, chilled water units, cooling towers, etc.
Our factory offers three models of products:
Standard Vibration Damper
2: Fixed Mount Vibration Dampers
3: Low-frequency adjustable vibration dampers (operate normally in environments from -30℃ to 100℃, with natural frequencies ranging from 1.8Hz to 3.6Hz and a damping ratio of 0.04-0.066) can be selected according to individual needs (Note: The adjustable vibration dampers with height H increased by 20mm)
