Rotating machinery vibration analysis. Structures vibration analysis Stesses measurements Simulator Premium A great machine for teaching bearings faults and balancing. On rotating machinery, bearings problems are very common. Their spectrum signatures must be understood to be detected more easily. It’s the same for the unbalance: a correct balancing ensures a good operating and improves the lifetime of the machine. This speed changing simulator can generate each kind of defaults separately or combined. Characteristics : Portable and robust Do a multi-plan balancing Create and identify the bearings fault frequencies Recognize the typological fault signature Develop signal analysis technics. For specific studies, 9 options kits are available Specifications : Easy to use, configurable, ideal for learning the basics of vibration analysis General: 1/2 HP AC induction motor with variable speed drive to 4,000 RPM, 110/220 Volts, 60/50 Hz, split bracket bearing housings with features for span reconfiguration, precision machined baseplate with vibration isolators. Dimension : 70cm20cm50cm Weight : ~20kg Rotors: 2 aluminum with one row of 18 tapped holes. Safety: Clear impact resistant cover.

However, a detailed investigation of a particular phenomenon requires additional attachments and fixtures. At SpectraQuest we have thought carefully about various applications of the MFS system. This brochure describes several Option Kits to be used with an MFS for performing different in-depth studies. Each Option Kit provides you with a wealth of information to increase your knowledge of rotor dynamics and machinery fault diagnostics. It is important to note that the MFS is versatile and can be configured in many more ways than those associated with the Option Kits Eccentric Rotor Learn the effects of rotor eccentricity on vibration spectra. Determine relationships between eccentricity and unbalance. Develop techniques to locate and correct the effects of eccentricity. Learn the effect of varying the mass moment of inertia on vibration amplitude. The kit consists of one aluminum rotor with an asymmetrically located center bore and one clamp collar Cocked Rotor Learn the effects of a sheave that has not been fitted to the shaft properly. Learn vibration signature of a cocked rotor. Develop methods to correct cocked rotor problems. Learn the effect of varying the mass moment of inertia on vibration amplitude. The kit consists of a cocked aluminum rotor and one clamp collar. Centrally Bent Shaft Demonstrate the signature of a bent shaft. Observe the difficulty associated with attempting to balance a rotor with a bent shaft. Bearing Fault Kit Deliberately faulted bearings to learn waveform and spectra of classic bearing defects. Learn about signal processing issues such as averaging techniques, leakage, and spectral resolution on determining bearing faults. Determine why ultra-high resolution spectrum is needed to diagnose a bearing fault when fault frequencies are located close to multiples of RPM. Learn how a large signal can mask adjoining low amplitude signals due to spectral leakage. The kit contains: one inner race defect, one outer race defect, one with ball defect, and one combination of defects. The fault frequencies are very close to the multiples of shaft RPM.

Toute communication, reproduction, publication, même partielle, est interdite sauf autorisation écrite de la part de la société Technivib International Cocked Bearing Kit Due to improper seating, bearings are sometimes not installed uniformly in the cavity, creating a cocked situation. Recognizing the signature of a cocked bearing is beneficial in that corrective action can be taken long before failure occurs. The kits consists of one bearing housing designed to exhibit this condition. 1" Diameter Shaft Bearing Loader Demonstrate how rotor loading affects bearing vibration amplitude. Location can be adjusted axially. A radial load on bearings shows the effects of loading and enhances the spectral amplitude. Sleeve Bearing Kit Waveform and spectral recognition of worn or loose fitting bearings. Fits the standard rotor shaft with grease lubricated, babbitt lined, sleeve bearings. Bearings are split so that plastic shims may be used to open the clearance to simulate increased looseness. Shaft orbital analysis. The kit consists of two customized pillow block sleeve bearings, two bearing pedestals, and mounting hardware.
