Dongkai Shuobang believes that the spring shock absorber is to reduce or eliminate the periodic vibration or instantaneous impact of the equipment due to its own operation or external influences, such as earthquakes. The natural vibration frequency of the entire equipment can be increased to separate it from the forced vibration frequency caused by external interference, thereby avoiding the same vibration of the machine.

Dongkai Shuobang believes that the HDL type spring shock absorber is an adjustable spring shock absorber produced by a new technology combining floor metal and rubber. The shock absorber adopts a large outer diameter spring, so that the shock absorber can better exert its superior shock absorption effect. It is a spring shock absorber that some small outer diameter shock absorbers cannot match. This shock absorber is also designed with adjustable bolts, which can adjust the height according to your requirements. The height of 60mm can be greatly adjusted, which can solve the problem that the unit is not level. Therefore, it is very suitable for fresh air units, combined wind cabinets and water pumps.

Dongkai Shuobang believes that HS type spring dampers are used for vibration reduction of small equipment such as fan coil units. In the central air-conditioning installation project, the vibration reduction installation of the fan coil unit can improve the operation condition of the fan coil, prolong the service life, and reduce the pollution of noise and vibration to the surrounding environment. According to the actual installation requirements of the fan coil unit, the special damper for the HS type fan coil unit is designed and produced. The product has the advantages of large damping, low natural frequency, convenient installation and low cost, and is especially suitable for installation and use in places with high requirements for the living environment.

Dongkai Shuobang believes that the narrow classification of rubber spring shock absorbers is as follows:

(1) Compression type. This rubber shock absorber is mainly used in the compression direction. The advantage is that the bearing capacity is large, but the elastic coefficient in the compression direction cannot be selected too low.

(2) Shear type. This rubber shock absorber is mainly used in the shear direction. Its load-carrying capacity is small, but it has the advantage that the modulus of elasticity can be chosen very small.

(3) The composite type is a rubber shock absorber used in the compression-shear combination direction, and has the intermediate characteristics of the compression-shear type.

(4) Cylindrical type. Dongkaishuobang believes that this type of cylindrical rubber shock absorber can be used for vibration reduction in vertical, axial, torsion, prying and other directions. The shaft used in the vertical direction is similar to the compression rubber alkali vibrator, and its bearing capacity is generally large, but the elastic coefficient cannot be selected too small.

Dongkai Shuobang believes that the advantages of rubber spring shock absorbers:

(1) Dongkai Shuobang believes that the shape can be freely determined, and the hardness can be controlled by adjusting the composition of the rubber formula, which can meet the rigidity and strength requirements in all directions;

(2) The internal friction is large and the damping effect is good, which is conducive to crossing the resonance area and attenuating high-frequency vibration and noise;

(3) The elastic modulus is much smaller than that of metal, which can produce large elastic deformation;

(4) No sliding parts, easy to maintain;

(5) Small quality, easy installation and disassembly.

(6) Dongkai Shuobang believes that the impact stiffness is higher than the static stiffness and dynamic stiffness, which is conducive to impact deformation.
