Vibration analysis allows us to evaluate the operating condition of your rotating equipment. Using the latest analytical resources, our certified analysts are able to capture real-time data and analyze your equipment for faults.
Vibration maintenance services:
- Bearing faults
- Mechanical looseness
- Structural issues
- Bent shaft
- Cocked bearing
- Gear faults
- Lubrication issues
- Flow turbulence
- And more…
Serious damage and downtime can be avoided with early detection and root-cause analysis of failure. Our engineers work directly with your maintenance personnel to identify failures, causes, and to address preventative measures.
Lubrication and Fluid Analysis
Oil analysis typically raises a few questions.
- How often should I change my oil?
- Am I using the right oil for the job?
- How clean are my high-pressure hydraulic systems?
- Is that noisy gearbox actually damaged internally?
The answers to these riddles lie in a good oil analysis program. Our advanced oil package solves these issues by testing the viscosity, checking for water, counting wear metal particles, measuring the Total Acid Number (TAN), and determining fluid cleanliness. All of these parameters can be determined by analyzing only 3 to 4 ounces of lubricant.
Commonly sampled components include diesel engines, critical bearing housings and gearboxes, as well as hydraulic systems. Our oil analysis programs additionally address a broad spectrum of industrial environments, including CNC machining equipment, water and wastewater plants, bakeries, and chemical plants.
One of the most powerful tools maintenance groups use is thermographic analysis, also called infrared inspection. Thermographic cameras detect radiation in the infrared range of the electromagnetic spectrum and produce images of that emitted energy. Because of this, thermography makes it possible to “visualize” the environment and variations in temperature, regardless of visible illumination.
Our certified thermographers are NFPA 70E trained, and qualified to perform inspection and analysis on all your power systems:
- Plant incoming power and distribution lines
- Motor control centers
- Local electrical cabinets
- Buss systems
Thermography can also be used to troubleshoot or analyze systems where temperature gradients need to be evaluated:
- Building envelope moisture and insulation analysis
- Furnace or freezer insulation failures
- Process operations and performance analysis
- Reactor analysis
- Machine tooling stress
- Steam systems
Motor Circuit Analysis
Motor circuit analysis utilizes computer-driven analytical equipment to collect electrical data on your electric motors and motor power feed systems. Our trained engineers use this data to determine the operating condition. Our expert technicians evaluate the electrical stability of your motors and provide recommendations for corrective actions in a controlled schedule.
Our engineers and analysts rely on engineering principles to develop action plans that can maximize runtime and availability of your motor systems. These principles include:
- Resistance Phase to Phase: The analyst evaluates the electrical connection conditions by taking micro-ohm level readings between each set of phases. A high resistance reading or imbalance between phases indicates a connection problem.
- Resistance to Ground: Commonly referred to as a Megger test. Our test equipment energizes the circuit using 500VDC or 1000VDC. The data results are compared against previous results, similar motor results, and IEEE standards. This data is then used to evaluate the electrical insulation condition of the motor and the power circuit.
- Capacitance to Ground: Capacitance data allows the analyst to evaluate moisture presence or contaminate buildup in motors. An increasing trend in capacitance level indicates increasing levels of moisture or contaminant buildup on the windings. The motor should be service to avoid deterioration of the insulation.
- Inductance Phase to Phase: Measurement of inductance between phases enables the analyst to evaluate winding and insulation condition within the coils. A significant imbalance and/or increase of gradients between phase readings indicates internal shorting of the coils. Advanced notice and maintenance will significantly increase motor life.
Additional testing can be performed for acceptance testing and troubleshooting tools, including Polarization Index (PI), Dielectric Absorption Ratio (DAR), Rotor Influence Check (RIC), and fault isolation testing.
