Dongkaishuobang It is believed that spring‑type vibration isolators are designed to reduce or eliminate periodic vibrations and transient impacts caused by the equipment’s own operation or external factors such as earthquakes. They can increase the system’s natural frequency, thereby decoupling it from the forced vibration frequency induced by external disturbances and preventing resonance.

　　Dongkaishuobang believes that the HDL-type spring isolator is an adjustable spring isolator manufactured using a new technology that combines metal and rubber. This isolator employs a large‑diameter spring, enabling it to deliver superior vibration‑reduction performance—something smaller‑diameter isolators simply cannot match. It also features an adjustable bolt, allowing you to fine‑tune the height according to your needs; with a 60‑mm adjustment range, it can effectively address issues caused by uneven equipment installation. Consequently, it is ideally suited for fresh‑air handling units, packaged air handlers, and water pumps.

　　Dongkaishuobang believes that HS-type spring dampers are used for vibration isolation of small equipment such as fan coil units. In central air-conditioning installation projects, vibration-isolating mounting of fan coil units can improve their operating performance, extend their service life, and reduce noise and vibration pollution to the surrounding environment. Based on the actual installation requirements of fan coil units, a dedicated HS-type damper has been designed and manufactured. This product boasts high damping, low natural frequency, convenient installation, and low cost, making it particularly suitable for use in environments with stringent residential comfort standards.

　　 Dongkaishuobang It is believed that the narrow classification of rubber spring shock absorbers is as follows:

　　(1) Compression-type. This type of rubber vibration isolator is primarily used in the compression direction. Its advantages include high load-carrying capacity; however, the elastic modulus in the compression direction should not be set too low.

　　(2) Shear-type. This type of rubber vibration isolator is primarily used in the shear direction. It has a relatively low load-carrying capacity, but its advantage is that the elastic modulus can be designed to be very small.

　(3) The composite type is a rubber vibration isolator used in combined compression–shear directions, exhibiting intermediate characteristics of both compression and shear modes.

　　(4) Cylindrical type. Dongkaishuobang believes that this type of cylindrical rubber shock absorber can be used for vibration isolation in vertical, axial, torsional, and prying directions. The shaft used in the vertical direction is similar to a compression-type rubber vibration isolator; it generally has a relatively high load-bearing capacity, but its elastic modulus should not be set too low.

　　Dongkaishuobang believes that the advantages of rubber spring shock absorbers are:

　　 (1) Dongkaishuobang believes that the shape can be freely determined, and the hardness can be controlled by adjusting the components of the rubber formulation, thereby meeting the rigidity and strength requirements in all directions;

　　 (2) It exhibits high internal friction and excellent damping performance, which is conducive to traversing the resonance region and attenuating high-frequency vibrations and noise.

　　 (3) Its elastic modulus is much lower than that of metals, allowing for significant elastic deformation.

　　 (4) No moving parts, easy to maintain;

　　 (5) Lightweight and easy to install and dismantle.

　　 (6) Dongkaishuobang It is believed that impact stiffness, being higher than both static and dynamic stiffness, is conducive to impact deformation.
