VIBRATION DIAGNOSTIC

We possess specialized experience in:

•           Control and diagnostic of work condition in plant and on working devices with the help of Vibscanner,

•           Centric fixing (Alignment),

•           Imbalance fixing (Balancing),

•           Fixing the condition of slide & rolling bearings.


POTENTIAL SAVINGS WITH VIBRATION DIAGNOSTIC

•           Bearing work life is increased,

•           Less losses of the El. power,

•           Less overheating of the El. motors,

•           Less number of overhauls and stoppages,

•           Predicting the stoppage with less consequences,

•           Longer working life of the El. motors, plant and working devices (pumps, reducers, ventilators, ...).

 

INSTRUMENTS CALIBRATION

•           Calibration of: manometers, regulators, indicators, recorders, transmitters (electrical and pneumatic),

•           Instrumentation erection, also as smaller repair of the instrumentation.

 

MEASURING AND TESTING OF THE EL. DEVICES

•           Testing the relay protection (planned up to 250 A, and secondary testing),

•           Testing dielectrically hardness of the transformer oil,

•           Testing the gas and thermal protection,

•           Measuring the grounding resistance spread,

•           Measuring the specific ground resistance,

•           Testing the protection out of indirect contact (loop resistance),

•           Measuring the insulation resistance on electrical installation,

•           Measuring and testing of all electrical devices (with or without raised voltage),

•           Measuring the insulation resistance and resistance at electrical device coil.

 

OUR ELECTRICAL OVERHAUL SERVICE DOES:

•           Revision/audit and erection of the electrical-installation, all types,
