We are offering profile cutting machine. Planned isolationthe isolation of machinery to prevent the transmission of vibration and noise has become one of the important phases of modern building engineering. Light weight construction and locating mechanical equipment on upper floors, adjacent to quiet areas, increases the requirement for vibration control. The use of isolation is primarily for reducing the effect of the dynamic forces generated by moving parts in a machine into the surrounding structure. noisean additional benefit of machinery isolation is the associated noise reduction. Introduction of a resilient medium between the equipment and the structure acts to break the path of structural borne noise. This results in noise reduction in areas outside the machinery room and to limited extent, in the area around the machine. This is achieved by reducing the sounding board effect normally associated with machinery mounted solidly to the structure. Use of isolation does not reduce sir-borne noise if found to be above allowable levels. Air-borne noise must be treated acoustically with acoustic enclosures or other sound absorbing devices. locationin evaluating and selecting an effective isolation system, consideration must be given to identifying critical areas. In buildings where equipment is located directly over or adjacent to quiet areas, offices, libraries, studios, operating rooms, etc., a very critical condition exists, requiring extremely high isolation efficiency. Basement locations and areas with high ambient noise such as factories, warehouses, power plants, etc., are considered less critical and can tolerate larger transmitted forces. In addition, the geographic location of the building is also important. If located in a designated earthquake zone, the potential seismic forces produced will dictate the incorporation of restraints to protect the resilient isolated equipment. elastomers describes natural rubber and the various synthetic materials such as neoprene. It possesses inherent damping and sound deadening characteristics and can be molded into any shape or hardness and vulcanized to metal. The term rubber-in-shear is used to describe the deflection in shear rather than compression.
