Characteristics of ZD Type Damping Spring Shock Absorber:

A variety of vibration and noise can affect the surrounding environment, harm human health, damage buildings, and reduce the accuracy of machinery and equipment, particularly causing interference to the use of valuable instruments. Moreover, the vibration itself can damage the machine, 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 vibration dampers are designed to incorporate the characteristics of steel spring dampers, overcoming the phenomenon of resonance when the damping ratio is low. They 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). Thus, our dampers maintain the low-frequency characteristics of steel spring dampers, achieving vibration isolation for high, medium, and low-frequency disturbances while also possessing the high damping ratio characteristic of rubber dampers. This allows for the elimination of the resonance phenomenon unique to steel springs, ensuring smooth operation from start to stop without excitation (amplitude A=0.01mm) and a stop time of 1.6 seconds. After installing the damper, the equipment can quickly pass over the resonance zone during start-up and shutdown without swinging, achieving an isolation efficiency of ≥85%. This makes the damper unnecessary to be anchored to large concrete bases, capable of supporting the total weight of the equipment, and suitable for installation on the ground, floors, and platforms. It can also be mounted without anchor bolts, significantly reducing the installation time. It is a simple, speed-appropriate, and economically rational multi-functional universal damper with a damping spring suspension design.

Our vibration dampers are equipped with springs made from 60Si2Mn spring steel, which offer advantages such as fatigue resistance, high strength, great load-bearing capacity, and long service life.

Main Application: Suitable for all types of dynamic rotating machinery, including fans, water pumps, compressors, generators, air conditioning units, water-cooled chillers, cooling towers, and more.
