Viscous vibration DAMPENERS FOR Gensets
DYNEMECH Spring Isolators, isolate high dynamic vibrations generated by floor-mounted industrial equipments such as compressors, blowers, generators which are prone to frequent start up and shut down, and equipment that is slow to reach operating speed. A spring isolator gives desired natural frequency to obtain phase difference in the frequencies for a rotating machine.
In many cases viscous damping is required to limit excessive
movement which could occur as a machine operates at a speed near to, or coinciding with the resonant frequencies of the system. They provide vibration isolation of 80-95%.
VIBRATION REDUCTION PADS IN USE IN HIGH SPEED DOUBLE TWIST BUNCHING MACHINE
Bunching machines are used extensively in wire and cable industries and are used for bunching copper, steel wires for varied applications.
Our Screw Support Mounts, Series DLC and Wedge Mounts, Series DF are used by high speed double twist bunching machines OEMs to provide foundation-free flexible mounting on vibration damping elements to adhere to OSHA guidelines for machine installation.
High rotation speeds, faulty bearings, gear tooth breakage, winding force etc. at high speed give rise to vibration which needs to be damped to improve production efficiency and reduce maintenance down time. Vibration values in bunching machines should conform to the standard. It can't be too high as it may cause problems with the main axis. Wire breakage problems in case of fine wire bunching can lead to huge production losses.
To avoid problems in wire guides/ bending sections and to protect electronic controllers against damage by excessive vibration our sturdy, circular Series DLC/DL mounts come handy. Furthermore, unbalances in machine or in case of machine installation on suspended floor, our anti vibration mountings provide the ideal machinery installation solutions with precision alignment and levelling, besides of course, vibration damping.
As we know today high prices of real estate in modern cities have propelled air-tight developments and compact construction which necessitate accommodation of large number of high speed production machinery, office complexes and sensitive machinery and equipments in the same buildings. Thus, mezzanine floors and upper floors are often added as a cost-effective way to increase square footage not only for storage but also for production purposes. As a result, newer buildings often do not dampen vibrations as well as older ones.
Add to this the noise and vibrations transmitted from nearby construction, manufacturing, transportation systems or HVAC installations in the same buildings. Moreover, builders save cost on modern floor slabs by making them thinner and lighter and increasing column spacing. This tends to make modern composite floors flexible and oscillatory.
And of course, vibrations are present in all operations involving machines and motion due to inherent exciting forces. But, such excessive vibrations, may lead to structural and mechanical failures, frequent breakdown and maintenance of machines, human discomfort and noise. Hence, cost effective measures need to be taken to reduce the vibrations within acceptable limits.
DYNEMECH vibration dampeners provide lower natural frequency than the frequency of the suspended floor (generally, the natural frequency of the pads should less than half of the frequency of the suspended floor) so that resonance is avoided besides, decreasing vibration amplitudes.
Dynemech has significant experiences in such scenarios as:
1. Installed many machines on suspended floors
2. Installation of machines which produce shock and vibration on operation like punch presses, shears next to the precision machines.
3. Sensitive machinery like Coordinate measuring machines(CMM) have been installed near press shop
4. Vibration Damping of Heavy duty power presses in residential areas
5. Highly dynamic machines like rubber mixing mill are accommodated on first floor
6. HVAC Equipments like Compressors , blowers have been installed on suspended floors
ANTI VIBRATION PADS FOR INJECTION MOULDING APPLICATIONS
Injection Moulding Machine have a lots of excitation sources consisted of servo motors, link system and inertia forces of the moving plate which can make excitation sources from low to high frequencies, besides the impact of mould closing and opening. Under these situations, installation of injection moulding systems on Dynemech Vibration Dampers is preferable to avoid the resonance phenomenon due to the various excitation frequencies and also absorb the shock of the moulding process.
Tear of the machine and tools.
To avoid moulding inconsistency, cyclic fatigue and failure and achieve reduced platen deflection, less mold wear, and better part quality Dynemech machinery mounting systems provide a variety of ant vibration mounts including Wedge Mounts, Series DF/DB, Screw Support Mounts, Series DLC/DLK/DML/DLM , DYNEMECH INSULATION PLATES and Die Cushion Pads.
Unlike other competitive anti vibration pads, where machines shakes when the die closes, Dynemech insulation plates provide increased stability and vibration reduction simultaneously on die closing/opening.
