Product Description
ZGT type damping spring shock absorber (enclosed type) is a product designed based on the low speed and large disturbance force of large-scale foreign chillers installed with unbalanced power equipment. This product has the advantages of great installation flexibility, good stability, low natural frequency, and significant vibration isolation effect. The ZGT damping spring shock absorber (closed type) is composed of multiple combined spring groups, upper and lower steel plates, and rubber anti-slip pads pasted on the outer surfaces of the steel plates. ZGT type damping spring shock absorber (closed type) is divided into ZGT-D type which is open type. ZGT-D2 type is closed type and has various specifications, or it can be designed and manufactured according to the special needs of users.
Under rated load, the corresponding vertical self-seismic frequency is 2.3Hz-4.9Hz, and the damping ratio is 0.02-0.06. It is an ideal product for active seismic isolation.
ZGT type damping spring shock absorber (enclosed type) can be placed directly under the equipment when installed. If the disturbance force of the power equipment is large, adjust the center of gravity first and fix the shock absorber base fixing holes on the foundation with bolts. ZGT type damping spring shock absorber (closed type) corresponds to the vertical natural frequency of 2.3Hz-4.9Hz under rated load, the damping ratio is 0.02-0.06, and the deflection can reach 75mm. It is an ideal product for active isolation.
Applicable equipment: chillers, diesel generators, punch presses, compressors, refrigeration units, transformers and other large equipment
Load range: 150-7000Kg
Support customization of special-shaped sizes and large loads
