The neoprene elastomer based anti-vibration pads and mounts have come a long way

The history: The equipment and machinery mounting pads are an important vibration control components used by the industry. Though there are a number of machine mounting pads available in the market you can make a choice depending on your requirement. They necessarily consist of a metallic portion that is bonded to the elastomer. About three-quarters of a century ago the machine pads were designed for shear loads. The shapes were circular or the parts were available in strip lengths so that they could be cut to size. However, the product failed due to overloading. The bond between the metal and elastomer gave way. As a result, the compression mountings came into existence.

Design changes and material selection: The machine mounting pads based on the compression principle can withstand overloading and have a deflection characteristic similar to the shear load mountings. Over a period of time, a lot of improvements have taken place and the machinery mounting pads are available in single and double deflection types. You can also opt for the machine pads that have the rubber bonded at the bottom of the base plate. These machine mounting pads do not require any anchoring as the friction between the floor and elastomer holds the machine in place. The choice of neoprene as the elastomer element was natural because of its resistance to oil and water. The machine pads with neoprene elastomers perform well in the harsh industrial environments. The top bolt secures the machine feet to the machine pad. The process of installation is extremely simple and all you have to do is to lift the machine and place it on top of the machine mounting pads.

A versatile product: The neoprene pad with an alternating height rib pattern is used to dampen the vibrations and noise caused by equipment that operates at medium or high rpm. Typical examples include transformers, generators, compressors, fans, pumps and air conditioners. The neoprene pads are about 10 mm thick with a load capacity of 0.05 Kgf/ mm2. The pads can offer a deflection of about 3 mm and we can use multiple pads in layers if the deflection requirements are higher. Neoprene has better environmental standing in harsh conditions as compared to natural rubber. The neoprene pads can work effectively in the industrial atmosphere involving water and oil.

The combination with a natural product: The neoprene cork pad is made from a pair of neoprene ribbed sheets with a cork center sandwiched between the two. The total thickness of the neoprene cork pad is around 25 mm. It has excellent resistance to ageing, compression set, water and oil. The loading capacity is the same as that of a neoprene only pad at around 0.05 Kgf/ mm2. However, the neoprene cork pads offer a much higher deflection at 4.5 mm. Here also multiple layers of the neoprene cork pads can be used for higher deflections. The applications include vibration isolation from compressors, generators, pool pumps, air conditioning units and a variety of other equipment.

Other anti-vibration products: For old pieces of equipment, simple vibration absorbers in the form of rubber squares and composite foam with a height of about 20mm are the most suitable. They can provide solace from the noise emanating from the vibrations shaking the whole support structure. You can slide them beneath the furnaces and they act as furnace thermal mounting pads. Care must be taken that they are not exposed to naked flame or molten metal. The furnaces are otherwise insulated and hence these products give the desired performance. The HVAC mounting pads are used for installation of the air conditioning equipment. As per the recent regulations, the HVAC equipment is to be mounted on the rooftops of the high rise buildings. Since these pads are exposed to the atmosphere, neoprene is the ideal choice of the elastomer in these vibration isolation pads.

Taking cues from the excellent properties that the neoprene elastomer exhibits, Andre HVAC International Inc. has come out with a wide variety of anti-vibration pads and mounts based on it. Neoprene alone and in combination with cork provides very effective vibration damping. Whether it is the machinery mounting pad or the HVAC mounting pad, an exclusive range is available from AHI in neoprene. You have to come with the dimensions, load and deflection requirements and make a selection from the catalogues and data sheets available online.

The significance of anti-vibration pads and sheets in your day to day life

We come across a lot of noise and vibrations in our routine daily life. The engine in the car, the washing machine in the house and the speakers of your music system are all producing vibrations when they are running. The vibrations, when transmitted to the surroundings, can cause damage to the other equipment and the support structures. This is because the transmitted vibrations cause the nearby machines and infrastructure to vibrate. Each and every structure and machine has its own natural frequency and if it is matched to the induced vibrations, it results in resonance. The vibrations can affect the accuracy of the machines and the resonance produces a cacophony which may make the working environment uncomfortable.

Pads for washing machines: The solution to the problem lies in the use of anti-vibration sheets, vibration suppression pads, and anti-vibration grommets to isolate the equipment producing vibrations and also to dampen the transmitted vibrations. You can use the anti-vibration mat or the anti-vibration pads for washing machines to get over the washing machine walking or other common vibration problems.

Mats for washing machines: The washing machine vibration dampers are made of elastomer compounds that not only reduce but also absorb the vibrations giving you a peaceful atmosphere at home. The anti-vibration mats for washing machines are made from compressed crumb rubber and very easy to install. These washing machine vibration dampers provide a durable cushioned surface that is perfect for washing machines and dryers.

Pads for speakers: In any sound system, you can invest in your mixer, mike, amplifier etc. but the most critical component to hear the recorded sound happens to be the speaker. You will not be able to get a true reproduction of your recorded sound until you use the speaker isolation pads to separate your monitors from the environment. The speaker isolation pads are designed to support virtually all sizes of bookshelf speakers and you can also use the wedge adjusters to angle your speakers.

Pads for equipment: The vibration pads for machinery help to dampen the noise levels and vibration frequency while safeguarding the fragile and sensitive components from external vibrations. The vibration absorbing pads are available in various shapes and sizes and can be custom made as per the customer requirements. The vibration pads for machines are available with ribbed, waffle, and suction cup options depending on the specific needs of the customer. While the natural rubber vibration absorbing pads suffice in most applications, you can go in for the neoprene ones where resistance to water, oil and harsh environment is required. The cork rubber pads and anti-vibration grommets are some other useful applications.

Sensing the need for the vibration dampening pads and anti-vibration isolation pads for use in homes and industrial applications Andre HVAC International Inc. came out with a wide range of such products almost 13 years ago. The anti-vibration pads home depot from AHI caters to the home requirement while you can also get a gamut of isolation products for industrial use also. These include compressor mounting pads, furnace thermal mounting pads, and anti-vibration pads for generators.

Vibration free environment helps in longer equipment life

Air compressor mounting pads: In the case of compressors the vibrations result from the unbalance of the rotating parts or from the attached piping structure. The unbalance is generated due to unequal weights on the piston pairs and is transferred onto the crankshaft. The piping structure resonates when some vibration in the system comes close to the natural frequency of the piping. The air compressor mounting pads not only dampen the vibrations but also provide for the ease of levelling and alignment.

The compressor machinery mounting pads have elastomeric elements and threaded centre bolts which offer a host of benefits:

  • Ease of installation with no requirement of anchor bolts.
  • Simple levelling and alignment leading to reduced wear and tear.
  • Reduction in vibration and shock
  • Longer running life
  • Better structural safety for the plant.

Furnace thermal mounting pad: The machine pads come are simple rectangular rubber pieces that come in several lengths and widths. They consist of an elastomeric element

and composite foam and are less than an inch high. They can be positioned below the furnace and the size and quantity are decided as per the weight and size of the furnace. The furnace thermal mounting pads are ideal for old equipment that creates a ruckus.

Anti-vibration pads for washing machines: The washing machines create a lot of vibrations due to the uneven load during rotation. The washing machines will walk during the work cycle even after the levelling has been done. The solution does not lie in anchoring the machine to the floor but to use the anti-vibration pads for washing machines. The visco-elastomeric property of the anti-vibration isolation pad ensures that the vibrations are damped and prevent the machine from sliding on the floor.

HVAC mounting pads: The waffle and ribbed anti-vibration pads are used for the mounting of the HVAC equipment. The waffle design has inbuilt suction cups and does not require any bolting. The waffle design ensures superior vibration damping. The multi-layered ribbed rubber pads offer both vibration and noise control. The waffle and ribbed HVAC mounting pads are meant for simple field installation and can be selected based on the load and deflection characteristics.

Cork and neoprene rubber pads: The cork rubber pad that has a cork core with rubber glued to both the surfaces. The arrangement of materials, forces sound to pass through zones of different density. The neoprene cork pads are especially recommended for acoustical control rather than vibration damping. The neoprene in the cork rubber pad provides it with good weather resistance. Similarly, anti-vibration grommets are used for isolating sensitive lab equipment and electronics from the supporting frames.
