• Erection and overhaul of all process equipment and constructions in process chemical industry,
Execution of mentioned works is in
workshops, with total surface 1800 m2, Workshop is
equipped with crane - lifting power 100 kN spread range 14,5 m, hook high 5
m. For execution of overhaul and erection works we offer crane truck with
lifting power 400 kN and hook high up to 40 m.
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, ...).
• 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.
