Strengthen your protection system with equipment isolation mounts

Vibrations can lead to a severe damage to your working systems, precision machines and your HVAC equipment. An effective deployment of hard rubber mounts and isolation mounts is needed to guard your equipment. Every machine or piece of equipment has its own natural frequency. When the induced vibrations from motors, fans, pumps etc. cause it to vibrate harmoniously at its natural frequency, resonance is created and produces a

heavy noise. The result is a loss of precision or damage to the machine. The equipment isolation mounts and hangers separate the equipment from the vibration source, thus bringing the damage under control.

Rubber anti-vibration mount: A properly installed hard rubber mount will lead to a reduction in the vibration and noise generated by the machine. The rubber anti-vibration mounts are responsible for creating a flexible connection to the machine. The energy from the

equipment is transferred to the equipment isolation mount which dampens the vibrations. The hard rubber mounts limit the level of amplification of the resonant frequency by dissipating energy in the system. The amount of damping must be kept under check, as an increase in damping tends to reduce isolation at higher frequencies.

Grommets rubber: We have sensitive instrumentation in our labs, homes and industry and it requires protection from vibration and shock. The anti-vibration grommet rubber is specially designed for these applications. These vibration absorbing grommets are made up of two parts, the insulator and the shoulder screw. The raw material used for the insulator is EPDM rubber, thus providing it with the requisite durability. The protrusions on the mating surface of the insulator provide the resilience to dampen unwanted noise and vibration. The instrument is anchored to the surface with the help of nickel plated screws.
Fan rubber mounts: Fans, like any other rotating piece of equipment, generate vibrations. Fans are like any other rotating part and generate vibrations. The fan vibrations can significantly become noisier when there is a rotor dynamic balancing problem. The fan rubber mount is quite effective in isolating the fan vibrations from the support structure. Thus, the support structure stays protected from vibration damage and noise is greatly reduced.

HVAC rubber mounts: The neoprene based HVAC rubber mount is ideal for mounting the air conditioner and HVAC equipment on the rooftop. The rubber mounting has a tapped hole in the center of the rubber mount and a flanged base plate. The whole rubber mounting is neoprene rubber based allowing for good corrosion resistance and deflection

properties. Whether it is a fan rubber mount or an HVAC rubber mount, both offer excellent noise control and vibration damping properties. The other HVAC equipment like the chillers and air handling units etc. are also mounted on the support structure with the help of rubber HVAC mounts. However, in case the HVAC equipment or the ducting is required to be suspended the HVAC rubber hangers or the spring hangers are preferred.
Cylindrical vibration mounts: The cylindrical vibration mounts are very similar to the other hard rubber mounts but only different in shape. As the name suggests the round cylindrical profile allows for easy placement and installation. There are plenty of variants of the cylindrical mounts. There is one with a threaded metallic insert bonded to it while the other has a threaded stud protruding out. The insert or the stud is used to fasten the equipment to the cylindrical vibration mount. The elastomer element remains in contact with the support structure or floor and generates enough friction to prevent the running equipment from moving. The twin-stud cylindrical vibration mounts have the threaded studs on each side with the elastomer in the center. These mounts are used to connect two pieces of equipment without the transfer of vibrations from one to the other.

Andre HVAC International Inc. made a modest beginning in 2003 and has grown from strength to strength over the years. As the name suggests the rubber mounts and isolators for HVAC equipment were the initial offerings from the company. Andre HVAC International Inc. is well known in the area of HVAC rubber mounts. The building owners work in tandem with AHI for installation of heating ventilation and air conditioning systems. The range also includes the anti-vibration fan mounts, cylindrical vibration mounts and grommets rubber. The hard rubber mounts and equipment isolation mounts are so well accepted in the market that they have spurred the growth of the company into rubber anti-vibration mounting range of products.

 

Vibration damping and isolation are the need of the hour

The rubber anti-vibration mounts and isolators have become a standard requirement as more and more people are becoming aware of the adverse effects of vibration and noise. Today, the isolation mounts are being widely used in refrigeration plants, compressors, HVAC equipment, diesel generators, fans, motors, pumps, presses and CNC machines etc. The elastomer can be natural rubber, neoprene or other compound depending on the requirement of resistance to ageing, compression set, water and oil. Let us take a look at the variety of the anti-vibration mounts and rubber hangers available.

Rubber grommets: The rubber grommet isolators provide the economical vibration isolation for light loads. The rubber bushings and rubber grommets are ideally suited for computers, disc drives, sensitive lab equipment and precision instrumentation.

Rubber bobbins: The rubber cylindrical mounts are also known as bobbin mounts and are used to curb both active and passive vibrations. The rubber dampers are effective in structure-borne noise control. A variety of combinations involving the stud and threaded hole at the two ends of the cylinder are available.

Rubber fan mounts: To prevent the transmission of vibrations from a fan motor to travel to the chassis, on which it is mounted, requires a rubber isolation mount to be put into place. The anti-vibration fan mount can be made from silicone and other rubber compounds in order to decouple the fan from the case and also attenuate the unwanted vibration.

HVAC anti-vibration mounts: The anti-vibration spring mounts that have elastomer core,

a coil spring and carbon steel bases are ideally suited for mounting of HVAC equipment like fans, AHUs, pumps, and motors. The rubber in shear isolators is also used for HVAC applications where a higher degree of stiffness is required in the horizontal plane and good isolation in the vertical plane. Thus, the rubber in shear vibration isolators provides a cost effective engineered solution for HVAC equipment mounting.

Hard rubber mounts: The hard rubber mounts are desired for high reliability and fine quality requirements. The hard rubber anti-vibration mounts are custom built and find the usage in automobiles, machinery and household electrical appliances etc.

Rubber hangers: The anti-vibration hangers are used for false ceiling suspension, HVAC ducting and piping suspension, and equipment suspension. The rubber hangers are primarily made from polymer material while the spring hangers make use of metal springs.

Anti-vibration motor mounts: The equipment like hexacopters and multi-rotors make use of the anti-vibration motor mounts to attenuate the vibration and noise from motors and props. The flight controller sensors function properly only when the rubber anti-vibration mounts significantly dampen the motor vibrations.

Andre HVAC International Inc. is a leading supplier of rubber isolation mounts, rubber bushings, and HVAC rubber mounts to name a few. AHI uses the best of material to provide a long service life and enhance the life of the equipment. Whether you are replacing a worn out mount or going in for a new application, AHI has the right anti-vibration mounting to give you the desired vibration isolation and noise reduction.
