Maintenance - Import export

Our field service teams carry out a wide variety of tests and measurements : Vibration analysis Laser alignment Dynamic balancing Oil analysis Electrical analysis Transformer analysis Thermography / Infrared Non-destructive tests (NDT – according to API RP 585, API RP 7G, ASNT SNT-TC-1A & ESC practices) Vibration Analysis Vibrations in a machine are generated by certain elements moving relatively to each other. These vibrations contain a lot of information about the condition of the machine and indicate whether there are problems or not. By performing a vibration analysis we can not only measure the severity of a particular problem, but in many cases, the exact location and cause of the problem. Vibration analysis can detect the following malfunctions: Imbalance Alignment error Eccentricity Bearing condition Condition of Gear Sets Belt and Pulley condition Mechanical looseness Electromagnetically induced forces
