14 work in situ at power plant
BBC 300 MW turbine

15 work in situ TurboCare uses own containers for site preparation.
Container city in Power Plant

16 work in situ Tool storage near turbine
Mobile lathe and mobile mill near turbine.

17 installation TurboCare is ready for:
assembling of old or new turbines on new foundation precision leveling of machine frames transport of heavy units to plants

18 instalation TurboCare installed in 2002 for Alstom – 3 skids with gas compressors system in Poland.

19 Major overhaul of 200 MW turbo – generator of LMZ design
steam turbine overhaul Major overhaul of 200 MW turbo – generator of LMZ design

20 gas turbine overhaul VANTA PP – Finland Gas turbine 80 MW

21 Diaphragm blade assembling New blades of turbine rotor
Compressor & turbine New blades of turbine rotor

22 hydro turbine overhaul

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 alignment Clearances measurement Non destructive testing Destructive material testing Material testing with replica Oil purity testing Photo documentation Video endoscopy Fact finding protocol Machine diagnose after overhaul

25 vibration diagnostic Vibration measurement Vibration analyze
Balancing at site Analyze 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 measurement Vibration analyze Cracks 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

30 turbine casings overhaul
Cleaning, NDT, cracks removing; Welding repair; Dimensions control; Machining; Bolts replacement; Assembling.

31 After overhaul turbine casings are ready for assembly.
turbine casings overhaul After 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 mm Run out after straightening – max 0,12 mm
