ACE solution for the decoupling of production machines ensures calm in chocolate production by reducing low-frequency vibrations to a minimumAt a renowned Belgian chocolatier, part of the production process led to vibration and oscillation in an adjacent house. Despite numerous tests, the manufacturer was unable to find a solution that could isolate vibrations below 20 Hz, until they came across ACE products. The PLM pneumatic levelling elements from the ACEolator range from ACE offer significant insulation from a frequency of 5 Hz and up. Now 14 PLM-3’s installed in the facility are reducing vibrations by 80 percent. Any remaining vibration can only be detected with measuring devices.

In an opera production a 3D HDD projector was supposed to project images onto the stage during performances. Standing as it did on a trolley, which was to be moved over a tiled floor, the projector was virtually unusable. The problem was solved by combining an increase in the projector frame to 10 kg with the assembly of pneumatic levelling mounts PLM-1 from ACE. PLM is located in the low-frequency range and is primarily used when measuring tables, test equipment and high-performance machines need to be perfectly isolated.

A university of applied sciences team optimises oil pumps to reduce the fuel consumption of combustion motors. Numerous tests are necessary for this. A test stand caused undesired vibrations. PLM air spring elements from ACE ensure damping at several points. The optimum design was achieved with the company-produced measurement case and an external measuring sensor that was connected to a tablet PC. The low-frequency elements provide a significant isolating effect from a frequency of 5 hertz and above, and prove themselves to be significantly more effective than the previously used rubber-metal isolators.

Measurements made on a glass measuring table led to unusable results because the isolator used was unable to cope with the lateral stiffness of the products used. Only the low-frequency pneumatic isolators PAL 21 from ACE with automatic level control could provide a remedy. A special feature of these membrane pneumatic isolators lies in the level control valve, which has, by virtue of its construction, an above-average longevity. Relatively large acceleration forces can lead to horizontal movements and it is particularly in such situations that the robustness and durability of the isolation system make a significant contribution.

Problem:A major problem that gas transmission and petrochemical companies are facing is piping fatigue and failure caused by vibration. High frequency (ultrasonic and hypersonic) gas pulsations that occur at natural gas transmission line compressor stations cause metal fatigue in the piping and valves. Problems also arise from "water-hammer" type shock impulses that occur. Excessive vibration therefore constitutes a great threat to the safety and reliability of gas compression and liquid pump systems.The vibrations not only cause rupture of piping, but also stud and bolt branch piping breakages, header and manifold breakages, and unwanted noise.Solution:To eliminate excessive vibration and design a safe and reliable piping system, a properly designed mechanical restraint is required.The application of Fabreeka® Preformed Fabric Pad within these mechanical restraints can provide:increased damping of piping vibrationsincreased thermal flexibility reduction of unwanted noiseIt also prevents:corrosion caused by metal-to-metal contacthigh stress pointsfrettinggalvanic actionnon-uniform clamp contact pressure.

For pristine sound, a manufacturer of hi-fi amplifiers relies on air springs from ACE. This effectively eliminates disruptive ambient vibrations that enter the demonstration room from a neighbouring workshop and disturb the listening experience. The PLM-1 air springs, which have a low natural frequency of 3 Hz, are used as a bearing in the hi-fi rack for decoupling. ACE was able to prove the effectiveness measurably with the company's own app VibroChecker PRO. In the meantime, the manufacturer offers the high-end amplifiers optionally with the air springs and the app from ACE to the end customers.
