Avmount Vibro Dampers are designed to use the isolating media, rubber in this case, both in compression and in shear. It is bonded to metal during vulcanisation such that the design makes the mounting have an equal stiffness in all directions. The mounting can be used for mobile applications also, since the base of the mounting is provided with holes for attachment to the chassis. It also has a friction pad bonded to the bottom of the base for proper fixation of the machine to the floor in case of stationary applications. Hence no bolting is necessary under these conditions.
Avmount Vibro Dampers can be used for installation and vibration isolation of COMPRESSORS, DIESEL GENERATORS, FANS AND MOTORS, AIR CONDITIONING UNITS, HYDRO EXTRACTORS AS WELL AS FOR THE PROTECTION OF MOUNTED EQUIPMENT FROM EXTERNAL VIBRATION OR SHOCK. Being of extremely robust design, their life is generally equal to that of the machinery or plant which is mounted on them.
Machinery mounted on our dampers isolates vibrations both actively and passively. The machinery is isolated actively in the sense that the machine which is a source of vibration is so isolated that the incidence of transmission of vibration to the floor upon which it rests is reduced to an extent, and passively in the sense that the machine which would be affected adversely by external sources of vibration is now insulated from them.
Applications of Vibro Dampers (Type AVM)
- Diesel Generating Sets Mounts
- Air Compressors Mounts (both Reciprocating Type and Screw Compressors)
- Fan Mounts and Motor Unit Mounts
- Centrifuges Mounts
- Air Conditioning Unit Mounts
- Combustion Engine Mounts
- Mixer Mounts
- Crusher Mounts
- Rolling Mill Mounts
Mounting Procedure for Vibro Dampers (Type AVM)
- Obtain the weight and the Centre of Gravity of the assembly to be mounted.
- If this is not readily available, obtain weights and respective Centres of Gravity of the individual units which make up the mounted mass. For instance, the engine, radiator, alternator, flywheel, base frame, etc. from a D. G. set.
- Determine the position of the Centre of Gravity of the assembly by reference to two vertical planes at right angles to each taking moments of the separate units about these datum planes and dividing the respective sum of these by the total weight of the assembly.
- Determine the disturbing frequencies which are usually primary and/or secondary orders of the slowest speed of the machine.
