BHEL
has collaboration with M/S Siemens for steam turbines and
steam turbines are under manufacture with this design. Earlier
collaboration was with M/S BRUNO AND M/S SKODA of Czechoslovakia
for which spares are manufactured and supplied.
|
|
|
Tests
carried out on steam turbine :
|
|
No
load mechanical run test is carried out as per international
standards API 612 and BHEL standard to prove:
|
|
a)
Vibrations of machine at no load .
|
b)
Oil flow to bearings.
|
c)
Bearing temperatures
|
d)
Performance of governing system.
|
e)
Tightness of oil and steam systems.
|
f)
Protections of turbine
|
|
|
4-Test
beds are available and simultaneously 4 machines can be assembled
at a time, 2- independent oil systems , common vaccum systems
and condensate system are available.
