Air Conditioning Shock Gasket

The role of Air conditioning shock gasket

Weakening the vibration transmitted by the fan to the foundation is actually eliminating the rigid connection between them, that is, installing a vibration damping device between the vibration source and its foundation. If the fan is installed on the vibration damping pedestal, the vibration damper or vibration damping pad is installed between the pedestal and the floor or foundation to cause vibration damping. The damping pads and dampers commonly used in ventilation and air conditioning equipment include rubber damping pads, rubber dampers, spring dampers, etc.

1.The rubber vibration damping pad has good rubber elasticity, large damping ratio and convenient manufacture. It is a commonly used and ideal vibration isolation material. One or more pieces can be stacked and used, but rubber is easily eroded by temperature, oil, sunlight, and chemical solvents, and is easy to age. This type of vibration damping device is mainly made of vulcanized oil-resistant nitrile rubber. The rubber vibration isolation pad is to cut the rubber material into the required area and thickness, and pad it directly under the equipment. Generally, there is no need for pre-embedded bolts to fix, it is easy to manufacture and install, but it is easy to age and deform, reducing the vibration reduction effect.

2. Air conditioning shock gasket and rubber shock absorber are cone-shaped elastomers made of nitrile rubber, and are pasted on the inner and outer metal rings to be subjected to shearing force. It has low natural frequency and sufficient damping, good vibration reduction effect, convenient installation and replacement, and low price. Under normal circumstances, when the equipment speed n>1200r/min, rubber shock absorbers should be used. The relevant product catalogs and design manuals provide the necessary parameters to select the shock absorber when the weight and static compression of the unit are known.

3. Air conditioning shock gasket and spring shock absorber consist of a single or several springs and cast iron shields of the same size, which are used for ground installation and hoisting of the unit. The natural frequency is low, the static compression is large, the bearing capacity is large, the vibration reduction effect is good, the performance is stable, and it is widely used, but the price is relatively expensive. In addition, there is a 10mm thick rubber plate under the bottom plate of the spring shock absorber, which can also play a role in sound insulation.
