We perform the complex investigations and expertise's of the steam and water boilers elements, distribution networks as well as another technical devices.
We perform the vibration diagnosis of the turbosets, ventilators, mills, pumps, electrical motors and another rotating machines.
The activity of the Department of Diagnosis and Control is based on the high qualifications and experience of the workers team, proved diagnostic methods and the highest class of applied instruments.
We perform the following diagnostic investigations:
• visual evaluation of the element stale
• measurements of the deflection grade, creep, ovalisation on the arches
• measurements of the wall thickness by the ultrasonic method
• identification of the materials sort by the steeloscope method on the sites
• full analysis of the chemical composition of steel by the spectral method
• detection of the cracks or another discontinuities of the surface by the magnetic or penetration method
• measurements of the fractures depth
• ultrasonic investigation of the metallurgical products
• ultrasonic investigations of the welded connections
• endoscopic investigations of chambers interiors, pipe connections, etc., - photographic documentation
• stationary and on the sites (making of replicas) metallurgical investigations
• stationary and on the sites measurements of the hardness
• determination of the operational degradation grade of the material
• determination of the margin of further durability
• strain gauge method of stresses investigations
• measurements of the boiler on the non-circularity
• estimation of the adhesion grade of bearing material to the housing
• determination of the mechanical properties of the metallurgical products and welded connections
• execution of substitute certificates of material quality
In the range of vibroacoustic diagnosis we perform:
• determination of the dynamic state of the investigated devices on the ground of the vibration measurements of the bearing housings
• periodic measurements (preventive)
• before overhaul measurements with recommendation according to the overhaul
• acceptance measurements after overhaul,
• computer analysis of vibrations
• frequency characteristics at the starting-up and stoppage of machine
• balancing of the rotors in own bearings
• laser alignment of the shafts of the machine sets with the horizontal and vertical axes
• laser control of rectilinearity and alignment of the spindles
• investigation of the technical stale of cages of electric motors by the method of the spectroscopic analysis of current
In the professional power industry we guide the systematic investigations in all plants of the Group of Thermal-Electric Power Stations in Lodz joint stock company and we cooperate with such companies as Rafako joint stock company.
