7.MANUFACTURING PROCESS

HYDRO TURBINES

The major processes involved in various Hydro Turbine Sections are as follows:

Marking and checking of blanks – manual as well as with special marking M/c.

Machining on Horizontal Boring, Vertical Boring, Lathes etc. as the case may be on CNC /Conventional Machines. Intermediate assembly operation is carried out on the respective assembly beds provided.

The sub-assemblies are further assembled for hydraulic/functional testing. Hydraulic testing is done using a power driven triple piston horizontal hydraulic pump, which can generate a pressure of 200 Kg/Cm2. It can also be carried out using a power pack.

On Governing elements / assembly and test stand, the components / sub-assemblies / assemblies are tested up to a hydraulic pressure of 200 Kg / c m2 using the piston pump. Oil testing upto 40 Kg / c m2 is carried out with oil pumping unit, which is permanently installed on this bed.

STEAM TURBINE

Processes carried out in various sections of steam turbine manufacture are based on the following main phases.

Machine section – Castings, Forgings, welded structures and other blanks are delivered to this section. The manufacturing process is based on the use of high efficiency carbide tipped tools, high speed and high feed machining techniques with maximum utilization of machine – tool capacity and quick acting jigs and fixtures.

Assembly Section – Casings and governing assemblies are hydraulically tested for leakage on special test Bed. Assembled unit of governing and steam distribution systems is tested on Governing Test Bed. General Assembly and testing of Steam Turbine is carried out on the main Test Bed in Bay-II.

OVERSPEED & BALANCING TUNNEL

Painting, Preservation and Packing – After testing the turbine, it is disassembled and inspected. Then the parts are painted, conserved and

packed for final dispatch.

GAS TURBINE

The major processes involved in manufacturing Gas Turbine in various sections of Bk-III are as

Machining

Castings, Forgings, welded structures and other blanks are received from concerned agencies in the respective sections. These are machined keeping in view optimum utilization of machine tools and toolings. Special jigs and fixtures are made available to facilitate accurate and faster machining. Proper regime and tool grades have been established to machine the materials like inconel, which have poor machinablity.

Main Assembly

Final assembly is done on test bed. Parts are assembled to make sub-assemblies. These sub-assemblies are again machined as per technological and design requirements and are made ready for final assembly. After assembly and insulation assembled Gas Turbine is sent to site.

Rotor Assembly

The rotor is assembled on Hydraulic Lifting Platform and sent to main assembly, where after checking clearances, it is sent for machining. After balancing, turbine side of rotor is disassembled, inner casing is fitted and rotor reassembled. This work is also carried out on Hydraulic Lifting Platform. Finally rotor is sent for assembly on test bed.

Combustion Chamber Assembly

This assembly is carried out on 3 tier platform installed for this purpose in Bay-I assembly. After machining of all components, ceramic tiles are fitted in flame tube. Burner and piping etc. is fitted in dome and combustion chamber is finally assembled. It is directly sent to site after insulation.
