PdM Specialists Services:
At its core, vibration analysis is dependent on known factors, while unknown mechanical aspects play a major role in creating or generating vibration. Our engineers and technicians will work with you to determine the criticality of your equipment, production loss if there is an equipment failure. We will then help with designing a program that fits your specific situation and budget.
Infrared Thermography (IR) has found many areas of use in the last 15 years. Through infrared thermography, PdM Specialists can measure escaping energy from electrical and mechanical equipment. By using a thermal camera, PdM Specialists can get a thorough picture of problems before they become catastrophic. The reasons for testing vary from safety issues, determining energy loss and overall equipment reliability.
While we are on-site, and performing this service, our technicians go the extra mile and record vibration data on all rotating elements associated with the component to balance. The motor is the often overlooked component, however bearings, pulley condition, electrical fluting (with VFD driven motors), often causes problems that could potentially cause more significant problems than an unbalanced rotor.
Using ODS we can visualize the movement of an entire machine, or diagnose a structural problem. ODS is a collection of vibration readings in reference to each other. The direction and placement of the sensor is critical in determining how a bearing pedestal may be moving in relation to another bearing etc. The typical results found are structural problems (which are identified) and resonance problems.
PdM Specialists has the capabilities for multi-channel (microphone) acquisition, or simple data logging of the sound at various locations and times. Our job is to define the magnitude of sound (sound velocity), and in some cases the octave band. In a few cases the exact frequency of an offending sound is needed in order to dampen or discover its source.
