Presentation Transcript

GAS TURBINE : 

GAS TURBINE A gas turbine, also called a combustion turbine, is a Rotary engine that extracts energy from a flow of combustion gas.

MANUFACTURING FACILITIES : 

MANUFACTURING FACILITIES HYDRAULLIC LIFTING PLATFORM: USED FOR ASSEMBLY AND DISSASEMBLY OF GAS TURBINE ROTOR. CNC CREEP FEED GRINDING M/C: THIS M/C GRINDS THE HEARTH SERRATION ON ROTOR DISC FACES. EXTERNAL BROACHING M/C: USED TO MAKE GROOVES ON OUTER DIA. OF ROTOR DISCS. CNC FACING LATHE: USED FOR FACING ROTOR DISC. CNC TURNING LATHE: USED TO TURN TIE RODS OF GAS TURBINE. GAS TURBINE TEST BED: USED TO FINALLY ASSEMBLE THE GAS TURBINE.

MANUFACTURING PROCESSES : 

MANUFACTURING PROCESSES MAJOR PROCESSES INVOLVED IN MANUFACTURING GAS TURBINE ARE MACHINING: One of the most important material removal methods, is a collection of material-working processes in which power-driven machine tools, such as lathes, milling machines, and drill presses, are used with a sharp cutting tool to mechanically cut the material to achieve the desired geometry. MAIN ASSEMBLY: Final assembly is done on test bed. Parts are assembled to make sub assemblies.

Slide 4: 

ROTOR ASSEMBLY: Rotor is assembled on hydraulic lift platform and send to main assembly,where after checking clearance it is send for machining . COMBUSTION CHAMBER ASSEMBLY:It is carried out on three tier platform. After machining ,ceramic tiles are fitted in flame tubes. Burner and piping etc. is fitted in dome and combustion chamber is finally assembly. PAINTING,PRESERVATION AND PACKING: After testing, turbine is disassembled and inspected then the parts are painted and packed for final dispatch.

BLADE SHOP : 

BLADE SHOP INTRODUCTION BLADE SHOP IS BATCH PRODUCTION SHOP COMPRISING OF VARIOUS TYPES OF CNC MACHINES AND MACHINING CENTERS,BESIDES VARIOUS SPECIAL PURPOSE AND GENERAL PURPOSE MACHINES. IN BHEL (HARIDWAR) BLADE SHOP IS LOCATED IN BAY-IV OF BLOCK-III.

3D –CNC COUNTER CUTTING MACHINE : 

3D –CNC COUNTER CUTTING MACHINE

MANUFACTURING FACILITIES : 

MANUFACTURING FACILITIES PLAIN MILLING SECTION: IT PREPARES ACCURATE REFERENCE SURFACES ON THE BLADE BLANKS BY MILLING AND GRINDING OPERATIONS. COPY MILLING SECTION: THE SEMI BLANKS PREPARED FROM PLAIN MILLING SECTION ARE FURTHER MACHINED BY COPY MILLING M/C. POLISHING SECTION: BLADE CONTOURS ARE GROUND AND POLISHED TO ACHIEVE THE DESIRED SURFACE FINISH.

Slide 8: 

4. INSPECTION DEVICE: 3D COORDINATE MEASURING M/C FOR TAPER AND RHOMBOID CHECKING MAGNA SPRAY CRACK DETECTION EQUIPMENT MOMENT WEIGHING EQUIPMENTS CONTOUR PLOTTER FOR PLOTTING OF BLADE PROFILE WITH VARIOUS MAGNIFICATIONS.

Slide 9: 

MANUFACTURING PROCESS OF TURBINE BLADES DEPENDS UPON TYPE OF BLADES eg:BAR TYPE,BRAZE TYPE,GAS TURBINE BLADES MANUFACTURING PROCESSES

BAR TYPE BLADES : 

BAR TYPE BLADES PROCESSES M/C TOOLS (a)BLANKING OF AREA MATERIAL: CIRCULAR SAW/BAND SAW. (b) SIZING TO RECTANGULAR SHAPE: HOR. MILLING M/C. (c) THICKNESS GRINDING: SURFACE GRINDER. (d) RHOMBOID MILLING: DUPLEX MILLING M/C. (e)TAPER GRINDING: SURFACE GRINDER. (f) GRINDING AND POLISHING OF: ABRASIVE BELT PROFILE POLISHING M/C.

Slide 11: 

PROCESSES M/C TOOLS (a)CUTTING OF DRAWN PROFILE: HOR.MILLING M/C. (b)THICKNESS GRINDING: SURFACE GRINDER. (c)CUTTING-OFF SPACER: ABRASIVE CUTTING M/C. (d)MILLING OF WIDTH: DUPLEX MILLING M/C. (e)GRINDING AND POLISHING: ABRASIVE BELT POLISHING M/C. BRAZED TYPE BLADES

GGAAA : 

GGAAA PROCESSES M/C TOOLS (a)CERROBEND CASTING: CERROBEND CASTING EQUIPMENT. (b)ROOT MACHINING: HOR. MACHINING. CENTER (c)LENGTH CUTTING: CIRCULAR SAW. (d)TENON: HOR.MILLING M/C. (e)GRINDING AND POLISHING: ABRASIVE BELT POLISHING M/C. GAS TURBINE BLADES
