Many organizations such as rotating machinery service companies, end users and machinery manufactures need a deep understanding of rotating machinery vibrodiagnostics. Various machine failures can occur in service and vibrodiagnostics is well established tool to identify these. RotMach Vibrostand helps to understand vibration patterns and fault specific symptoms of rotating machinery, all in one rotor kit.
Rotating machinery training
RotMach vibrostand is an excellent, cost effective and safe rotor kit that helps to gain a hands-on experience with rotating machinery vibrations. Vibrodiagnostic and machinery personnel can be trained in rotor balancing and vibrations patterns associated to various component failures. And it all takes place in home workshop, without pressure of maintenance or production time schedule and a risk of compromising the expensive machinery.
Machine learning applications
To learn effectively for machine learning algorithms like neural networks there has to be a large amounts of input data. Our rotor kits can be used to generate real world data that authentically represent the faults of large rotating machinery. Various kinds of machinery faults can be simulated and its vibration pattern generated on a compact size machine, in a controlled laboratory environment.
Vibrostand design
Special attention has been focused on user friendly design. Roller bearings are mounted on shaft via tapered adapter sleeve and locking nut. Change of roller bearing or adjustment of bearing span is a matter of minutes. Rotor speed is controlled by variable speed drive with LCD controlled unit. Upon request, customer specific motor driver can be installed.
Our vibrostands consist to a large extent of standard market available, CE approved components. Spare parts are readily and widely available. Tailor made components are manufactured under strict quality control, based in RotMach‘s long term experience in rotating machinery manufacturing.
Sensors and diagnostics
Our vibrostands can be equipped by range of third-party sensors from temperature and absolute vibration sensors up to eddy current probes monitoring the relative shaft positions. Probe mounting locations are compatible with mainstream market sensors. Upon request, we can deliver vibrostands with pre-installed sensors based on customer specification.
Customization options
High level of various customizations is possible. On customer request a specific configuration can be designed. Based on years of hands-on experience with rotating machinery, RotMach is also ready to extend the vibrostands with components like compressors, pumps etc. upon a customer specific request. Various rotating machinery phenomena can be studied or control algorithm strategies on compact models validated. All at a fraction of the cost of real size machine testing.
