23 kaplan turbine overhaul TurboCare is prepared for major and medium overhaul of hydro – turbines.Kaplan turbine rotor is dismantled for cleaning, measurement, NDT and overhaul.TurboCare can perform services of all types of hydro turbines.
24 fact finding Machine diagnose beforee overhaul Measurement of alignmentClearances measurementNon destructive testingDestructive material testingMaterial testing with replicaOil purity testingPhoto documentationVideo endoscopyFact finding protocolMachine diagnose after overhaul
25 vibration diagnostic Vibration measurement Vibration analyze Balancing at siteAnalyze of blades vibration
26 Grit blasting with cooper slag sand, aluminum oxide and glass pearls
27 non-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;
28 non-destructive testing Work in high temperature with high stresses is the source of cracks of turbine parts.
29 endoscope 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
31 After overhaul turbine casings are ready for assembly. turbine casings overhaulAfter overhaul turbine casings are ready for assembly.
32 turbine 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.
33 turbine rotors straightening Run-out before straightening – to 5,40 mmRun out after straightening – max 0,12 mm
38 Mobile boring machine WK-1 mobile machinesMobile boring machine WK-1Bore diameter – to 2600 mmRadial feed – to 200 mmAxial feed – to 200 mmMax. Length of inner part of casing – 4600 mmMachining the bore of IP 200 MW turbine casing
39 Mobile boring machine WK-2 mobile machinesMobile boring machine WK-2Bore diameter – from 1300 to 4000 mmBearings distance – 5030 mmWeight – kg
