ZD Type Damping Spring Damper Characteristics:
Vibration and noise of various types can affect the surrounding environment, harm human health, damage buildings, and reduce the accuracy of machinery and equipment, particularly causing interference in the use of valuable instruments. Moreover, the vibration itself can damage the machinery, shortening its service life. Therefore, isolating vibration with elastic elements and preventing its transmission is an ideal method to eliminate vibration, protect the environment, buildings, and 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 ensures that the isolation rate does not decrease when the damping ratio is increased to 0.15-0.18 (for higher damping ratios, 0.085). Thus, our shock absorbers possess the low-frequency characteristics of steel spring shock absorbers, achieving isolation effects on high, medium, and low-frequency disturbances while also having the high damping ratio feature of rubber shock absorbers. This eliminates the resonance phenomenon specific to steel springs, protecting equipment from vibrations (amplitude A=0.01mm) during start-up to shutdown without excitation. The shutdown time is 1.6 seconds. After installing the shock absorber, the equipment can quickly traverse the resonance zone during start-up and shutdown, ensuring stability without oscillation, 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 without the use of anchor bolts, significantly reducing the equipment installation time. It is a simple, speed-appropriate, and cost-effective multi-functional universal shock absorber with damping spring suspension.
Our vibration dampers are equipped with springs made of 60Si2Mn spring steel, offering advantages such as 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 boxes, chilled water units, cooling towers, etc.
Our factory produces three models of products:
Standard Vibration Absorber
2: Fixed Mounting Vibration Absorber
3: Low-frequency adjustable vibration dampers (operate normally at -30℃ to 100℃, natural frequency range: 1.8Hz to 3.6Hz, damping ratio: 0.04-0.066) - Users can select according to their specific needs (Note: The height H of the adjustable vibration dampers is increased by 20mm)
