How To Reduce Vibration ????

All Industrial machines generate vibrations and these vibrations are damaging the internal parts, bearing gears and shafts of the machine. For ex. Vibrations in Generators can travel through an entire building structure and cause annoyance and constant irritation to the building inhabitants. Similarly, a large compressor mounted on a factory rooftop can create massive vibrations during intermittent start-ups and stops. While you can reduce vibrations in these machines by following proper maintenance schedules, the truth is that eventually when the machine (generator or compressor or motor or pump) gets older, the maintenance costs and maintenance downtime increases. In this case, vibrations are not totally UN-avoidable. The machines will vibrate. But what can be easily accomplished is mounting the machine on new Anti Vibration Pads. The Anti Vibration Pads are made from vibration absorbing materials like springs, rubber or air. The major advantage of these Anti Vibration Pads is that while they do not stop the actual vibrations inside the machine, they can effectively isolate all vibrations being produced by the machine. In other words, the vibrations produced by the machine are not transmitted beyond the Anti Vibration Pads

Seismosys Technologies isolators come in a big range of static deflection to offer highly efficient vibration isolation system for any application. Roof top HVAC installations require minimum static deflection of 15mm and if the equipment’s are slow speed (~500

rpm) the static deflection should be 25mm. Rubber anti vibration pad with static deflection in the range of 6 to 8mm is too stiff to provide any significant isolation. In fact, it would amplify the vibrations due to resonance with slow operating speeds. Highly flexible spring isolators are the right choice.

Roof top installations needs high static deflections and the same can vary from 10mm – 30mm leading to vertical natural frequency ranging from 5 Hz to less than 3 Hz. Low operational speeds are best isolated with high flexibility. Single spring sleeve damping isolators is used for lighter loads and multistring sleeve damping for heavier load. The larger base plate of SR type shock mounts reduces the load bearing capacity requirements of the roof slabs. Vibration & Structure borne noise transmission can be almost completely avoided using isolators directly under the chillers. Inertia mass may not be necessary. Seismosys Technologies offers Isolation for Diesel Generator Sets. DG-sets using spring support has been a great success in the world market in competition to the standard rubber support systems. Our system with very low natural frequency offers high vibration isolation efficiency in the range of 95%. Life of the mounts is high, hence no replacement or maintenance – only one time cost. The mounts do not react with the leaked oil of the DG set, whereas a rubber pad has the tendency to expand when contact with oil or any fluid. Bolting to the machine or to the foundation is not necessary.

Chillers, DG

For HVAC Applications


The blower inside the Air Handling Unit (AHU) rotating at high speeds can cause heavy vibrations, especially when they are located on steel structure or roof tops. High Static deflection spring isolators works very well especially if the support structure is flexible. Since it is difficult to predict where the AHU will be placed it is always better to go with static deflection between 15 to 25mm. There are improved designs over the open spring type isolators. The spring is enclosed in self-locking type housing

AHU

Pipework supports - Spring Hangers

Seismosys Technologies spring hangers (SSH) are designed to design to isolate suspended sources of both noise and vibration. Suspended mechanical equipment such as in-line fans, cabinet fans and piping and piping and ductworks. These are available in a wide range of load and static deflection selections. The spring deflection for the piping from the chillers and pumps has deflection equal to the rotating equipment. Pipes supported off the floating floor have deflection to provide very low natural frequency.

Centrifuges

Vibration control of centrifuges is always recommended, as they are sitting on flexible steel structures in most cases and the natural frequencies are always in the range of the centrifuge speed. To keep the response motion within limits when passing through resonances of the spring supported centrifuge especially during the operation of a centrifuge with variable speed in such a resonance, damping is of extreme importance. For these cases our spring units with integrated visco-damping fluids will provide the necessary Isolation.

Embroidery Machines Installed at upper floors can cause high vibration transmission. Isolation are multi spring mounts that can eliminate vibration transmission. Seismosys Technologies Vibration mounts work with 90% vibration efficiency, vibrations are not felt even while standing next to the machine. We have been appreciated by our clients for their increase in productivity, as our mounts help the machine run smoothly at rated speeds and less amount of thread breakage. The four corners of the machine feets are supported on multi-spring SR type isolators, and center legs(if any) on the single spring type isolators. The conventional anti vibration pads or rubbr pads mounts don`t work well on Embroidery machines due to the resonance between the rubber mounts and the operating speed range of 500 to 800 stiches per minute. In fact, the rubber feet do more harm to the Embroidery machine. Our mounts keep the machines running smoothly with lesser wear and tear, leading to better machine availability and lesser maintenance. In many a cases where rubber mounts were observed to produce high internal vibrations and high vibration transmission, replacing them anti-vibration spring mounts solved the problem completely.

Embroidery Machines

Presses

Metal working presses create shock vibration in the frequency range between 10 to 20 Hz depending on their frame construction. Taller presses are expected to create lower frequencies, whereas the shorter and sturdier press frame frames are likely to create high frequency vibration. The shock mount require under the presses needs to absorb and dissipate this energy. Impact energy is consumed by the work piece with in the press frame, however the shock frequencies get transmitted through the ground and can be felt as vibration, even at long distances from the press. These shock frequencies need to be isolated to allow vibration free neighborhood. Presses on spring isolators are expected to move in response to any imbalance/inertia forces in the machine however, such an effect can be controlled by distancing the spring units further apart. Vibration damping by the conventional rubber mounts is not very effective in case of presses and there is hardly any isolation, one can easily feel the vibrations near the presses on rubber mounts. Though the presses on rubber anti vibration pad may look stable but, the foundation experiences good amount of dynamic load. We at Seismosys have Anti Vibration mounts with controlled damping which is provided by using visco-elastic gel. The damping is such that, the energy gets dissipated and at the same time press comes to rest well within the next stroke. Typically. In a press shop there can be sensitive machines like CMM`s, Machining centers and tool room machinery. Performances of these sensitive machines can be affected by the press vibrations. Spring support of presses eliminates vibration transmission to these sensitive machines and they can be located closer to the presses. The alignment of a rigidly mounted press can change over time due to loosening of foundation bolts due to oil seepage, where as a spring supported press is an “always” aligned machine. Since the dynamic load is almost completely absorbed by the Seismosys Isolators, smaller presses i.e. weighing up to 20 tons can be easily supported directly on the shop floor without constructing a foundation. This allows flexibility to relocate the presses easily, when required.

Forging Hammer

The impact energy is consumed by work piece with in the hammer frame however, the shock frequencies get transmitted through ground and can be felt as vibrations, even at longer distances from the hammer. These shock frequencies need to be isolated to allow vibration free neighborhood. Transmission of these frequencies depends on the soil frequency. The soil frequencies vary with the type of soil like rocky, loose or hard soil condition. The soil damping varies from being very low in rocky condition to very high in loose soil condition. Vibration transmission is high when the soil damping is low.

Coal Crushers

Vibration isolation of crushers is a must as the random frequencies generated by crushing can cause resonance in steel structure and lead to failures. The safe way is to isolate using highly flexible springs with adequate damping. Conventional anti vibration mounts or nati vibrational materials do not work in these cases. Crushers’ isolation is a specialized design and involves a big inertia mass that sits on a well-designed vibration isolation system comprising of spring units and visco-elastic dampers. High imbalance/inertia forces of crusher require concrete block inertia mass to stabilize the installation. Seismosys Technologies can design & supply the complete vibration isolation system including the RC block civil engineering with static and dynamic analysis of the RC block. The spring units are pre-stressable, can be inserted or removed in compressed (locked) condition. The visco-elastic dampers can be integrated in to the spring units or can be external stand-alone dampers.

Wire rope mounts SWM

Sensitive and expensive machinery like medical equipment’s, lab equipment’s etc., need to be protected against the harsh effects of bumpy roads. Wire Rope isolators come in handy, as they can provide high flexibility combined with high lateral resistance. SWM types anti vibration mounts are made with special anti-vibration rubber to delay ageing and resistant to heat and oil. The mount is specially shaped to provide for high static deflection that would be needed to isolate the lower frequencies. With SWM anti vibration feet to the packed sensitive equipment, vehicle can cruise on rough roads, without having to worry about the cargo.

Seismosys Isolation for Building & Structures

Earthquakes are vibrational motion of the grounds on which the structures stand. Motion induced in the structures by earthquakes is closely related to the vibrational characteristics of the structures. When the natural periods of the structure are close to those of the prevailing ground motion, the motion of the structures can be destructive. This type of motion can often be controlled by means of anti-vibration technology quite commonly referred to as seismic isolation.
