Considering the cost, Party A will mostly use rubber cushion to reduce the vibration. The advantages of this method of shock absorption, such as low cost and easy installation, are incomparable. Some air-conditioning manufacturers will automatically take rubber cushion when their goods leave the factory (such as Trane air-conditioning).

Six Advantages of Rubber Isolator for Shock Absorption

As a shock absorber, rubber isolators have several advantages:

_1. The shape can be determined freely. The hardness can be controlled by adjusting the composition of the rubber formula, which can meet the requirements of stiffness and strength in all directions.

2. Great internal friction, good shock absorption effect, conducive to cross the resonance zone, attenuate high-frequency vibration and noise.

_3, the elastic modulus is much smaller than that of metal, which can produce larger elastic deformation.

_4. No sliding part, easy to maintain.

_5, small quality, easy to install and disassemble.

_6. The impact stiffness is higher than the static stiffness and the dynamic stiffness, which is beneficial to the impact deformation.

However, the problem of life seems to be the "dead hole" of rubber isolators. For the more thimble, Party A will require Party B to provide spring isolators. In the selection and installation, spring isolators are not dominant, especially in terms of price, which has become the main constraints. Central air-conditioning does not seem to require such a high-priced isolator, and conventional cushions can also meet operational requirements in most cases.
