25vibration diagnostic Vibration measurement Vibration analyze Balancing at siteAnalyze of blades vibration
26Grit blasting with cooper slag sand, aluminum oxide and glass pearls
27non-destructive testing Flaw detection and metallographic tests:Vibration measurementVibration analyzeCracks test in turbine casings and rotors;Magnetic particle test in UV rays of turbine blades;Ultrasonic test of shafts, couplings, casing joint surfaces, bolts and bearings;Endoscope test of hard to reach spaces;Visual examination of pipeline interiors with micro TV system (length up to 11m);Flaw examination of rotor central bores;Metallographic replicas for assessment of technical degradation of materials working in highest temperatures;Hardness measurement for assessment of material condition;
28non-destructive testing Work in high temperature with high stresses is the source of cracks of turbine parts.
29endoscope test OLIMPUS - F7mm, 1,5 m long (photo registration); SONY – F6mm, 3 m long with video registration and dimensions measuring system;TV camera – F30mm, 11 m long
31After overhaul turbine casings are ready for assembly. turbine casings overhaulAfter overhaul turbine casings are ready for assembly.
32turbine casings material structure rectify After hours of work, high temperature and stresses destroyed material structure of turbine casing.Heat treatment is the best way to rectify the material structure.Crystal grain before and after normalization of turbine casing material.
